In the daily operations of any organization, typically the end users are responsible for a wide range of actions that compromise the safety and / or network performance.
However, even the pros have their bad habits: ignore users, do backups, not having defined procedures and other sins that undermine the image of the area.
To remind them that even the gurus are human, see below the 11 differences between a GOOD and an EXCELLENT IT engineer:
1. Acquisition Of Resources
When you want additional features, the network professional need to justify the request. A good engineer sends emails to the boss asking for more budget. A great engineer uses its monitoring systems to create a complete list of the use of each device and show how additional investment in hardware or bandwidth will improve the use of resources and increase business efficiency.
2. Identification Of Critical Alerts
Too many alerts means that network administrators will not be able to see the most critical alarms. A great engineer creates schedules and alerts that warn of more serious problems and ensure that the right person with the right skills, receive an alert.
A good engineer monitors the network. A great engineer develops panels that are able to submit all the necessary data to find problems before they cause real problems for users, such as problems related to storage or overloaded access points (wireless). Never wait for the phone to ring with news of an outage on the network – one great engineer must make sure that he will be the first to become aware of a problem.
4. Sharing Knowledge
How IT is an essential part of any business, one great engineer must use their understanding of the system to management and key users informed about the performance of its features and what it can do to help improve a difficult situation.
5. “I will document later”
A good engineer can add, remove or distribute assets, or assign or change IP addresses, but when lunchtime arrives, he leave the document to update later … and often forgets! A great engineer records the changes immediately. Even a basic change in management system that facilitates the registration of change is better than none. An incomplete or outdated documentation is source of problems.
IT is such an essential business to ask if there is a crash or hardware failure – on an individual computer or a major systems – A great engineer will set deadlines for responses and notifications to the team. The help desk should confirm receipt of a ticket at the time he arrives, with clear feedback about response times, and routing options if they are not satisfactory.
7. Don’t Leave The Updates To Check Tomorrow
Such as virtualization, cloud or BYOD – - When new technologies emerge one great engineer does not leave them for the next day or expect someone else to try to learn about them. New technologies are inevitable and always worth learning something new.
8. Formula For Disaster
Do not let huge flaw trigger and create a disaster recovery plan: Develop and test the plan in advance. A great engineer ensures the implementation of a contingency plan, data backup and proof of successful restorations. Review the plan and schedule regular simulations of disasters, even if only once a year or when new administrators assume functions related to recovery.
9. Password – Approve or Reject
Many network administrators tend to use the same password on multiple servers, applications and network devices. If a user does not get approved access to a less critical one system is extremely easy to compromise the core of critical systems using the master password.
10. Police Administrators
You have access policies and auditing deployed to users, but you also police the administrators? We often think that procedures add workload to the administrators and overload, preventing to resolve an emergency situation. However, the excuse of “doing things faster” should not mean no supervision, even the older managers. A great engineer implements a simple mechanism for auditing and reviewing occasional access. For larger teams with different levels, implement role-based, appropriate to the responsibilities of each controls.
11. Ignore The Capacity Planning
Many IT administrators expect the shortage of assets (network equipment, PCs, servers, mobile devices, wireless networking, storage etc.) to request additional equipment. A great engineer is ready for unexpected situations such as a high volume or simultaneous failures, especially when the supplier takes time to provide the equipment.
Despite all the risks that are reported on the cloud computing, the cloud business solutions have proven to be beneficial for companies to generate competitive value compared to its competitors who are not in the cloud.
Though the answers to the question “My business should adopt the cloud” are always “it depends”, there are reasons to be considered by businesses of all sizes to make the cloud your “vehicle” toward higher productivity, lower IT costs and greater growth. Here are 3 reasons why you should consider migrating your business – or at least many of its functions and processes – to the cloud:
Reason # 1: Optimizing Workforce
Reason # 2: The Cloud Helps Leverage Resources of your Business and Implement the rule of 80/20
The cloud can help you leverage your business, since it is linked to increased productivity – time, energy, money. An example is the possibility of increasing the capacity of entrepreneurship, to enable the owners of organizations do more with less: You can manage multiple companies with cloud.
Piyush Somani, Managing Director and CEO of ESDS says, the biggest advantage is being able to access the cloud completely from anywhere in the world using any Internet connected device, which can mean a savings of hundreds of thousands of dollars per year. According to the law 80/20, he explains that the cloud solutions enable companies to manage 80% of the business processes, which include the basic needs: sales, payroll, costs, services, etc.
Reason # 3: Migrating to the Cloud is a Business that is Low Risk Investment and can Generate ROI
With regard to investments, the adoption of the cloud is a low-risk move, which can generate a high return on investment (ROI) in terms of money saved. The operating costs of the cloud decreased 40% in energy costs, and increase business efficiency.
If your company does not use cloud computing as part of daily operations, there is a good chance to break into the model in the coming time.
One of the main benefits of the cloud is its ability to outsource the infrastructure and management of complex applications and data services, allowing data center managers to purchase computing cycles and storage capacity in a more granular fashion, on demand. Instead of spending capital in bulk for large servers and storage solutions, you can buy time based computer on actual usage of CPU cycles and the amount of gigabytes or terabytes in storage used.
Migrating critical data and applications to the cloud can be significantly more cost effective than maintaining the hardware at the company. As your data is stored on the service provider’s infrastructure, there is no need to invest in the purchase of equipment, maintenance or upgrade the web hosting server.
In addition, as data and software are under the responsibility of a provider, the contracting company can reduce the number of IT employees or contractors needed to keep the hardware running on premise, directing them to more strategic activities that add value to the business.
When migrating data from the company to a company that specializes in providing cloud computing solutions, the organization is not only investing in a solution of off-site storage, but also buying a little tranquility. This is because providers of cloud solutions as Amazon, IBM, Cisco, Microsoft and ESDS have trained staff which is ready to respond to emergencies, frustrations and failures 24 hours a day, 365 days a year, ensuring that the company and employees have access to files and business applications. Furthermore, they give the necessary assistance when requested. By default, cloud computing offers a backup solution instant off site that is running. In cases of disasters in the office, for example, business continuity is assured, thanks to the fact that information is replicated to another location.
Having a solution of cloud computing means to grow rapidly and meet the demands of employees and customers. As businesses grow, the cloud-based solution can quickly be scaled to meet the growing needs. Such movement may be especially important for businesses that rely on web sales as a significant representation of the recipe. The lack of server capacity can quickly result in lost sales.
In essence, the cloud changes its cost structure and managing IT from the purchase of equipment, hiring professionals and operation of internal data centers to service-oriented paradigm on which you buy just what you need when you need. Becomes someone else’s problem to make sure everything is secure, available and reliable.
However, there are always advantages and disadvantages to surrender control of IT to another person. You need to make sure it is worth it, and it works.
Here are ten points to consider before adopting the cloud:
All these factors are important and must be considered when you evaluate whether cloud computing makes sense for your organization or not!!
The cloud as a concept has become ubiquitous in all technological news blogs, newspapers, etc.. So much so that we tend to lump it services or functionality we use for years or even decades. Most people ask but do you really what is this cloud? or what do you have again? If the end is all easier …
The cloud is basically flexible, they have the ability to increase and decrease in resources based on the needs you have for a project at all times. Traditional servers are limited to the hardware installed and of course, any extension of RAM, disk space or processor involves turning off the server and manually replacing parts. On the other hand, create an additional VPS to meet peak demand is a matter of seconds, while always ready to maintain a physical server these cases is costly.
How have ESDS focused on Cloud?
The first is developed its own eNlight Cloud Hosting Solution to ensure our independence when going to implement new features and improvements. In fact we are the only company in India using a solution developed in house and certainly in ESDS, we prefer to maintain control over the platform without relying on third parties.
Another point is the problem of storage. First Cloud (and many today), lacked stability and performance for virtualization was performed on conventional storage structures. Moreover, as it is not possible to virtualize on demand access to disk solutions like Amazon tarifican the number of requests to cabins with high capacity storage.
In that sense we have been clear that the utility of Cloud had to rely on the speed of response and processing power and network. Why we use the highest quality hardware servers, faster Gigabit connections … and drives: SAS in RAID in compact and efficient cabins, otherwise it would not be possible to offer a useful tool!
Whether you realize it is a classic consumer computing lifetime and not much different from a mail service for IMAP or file repository. The hosting companies offer this service since they exist, for example in ESDS we developed eNlight Platform. With the proliferation of the first laptops and mobile devices then, has been imposed demand to centralize photos, music, documents, etc..
Another classic converted, but this time very common in the 90 companies and universities: networked applications. The jobs are simple terminals, “stupid computers” that are connected to a centralized software, eg. a project manager or an office suite … has been and still is a good way to lower licensing costs.
For our part we think it’s not worth giving up the power that gives you any conventional PC or laptop to run desktop software connected to a central server. In fact, offering more specific applications is gaining licenses cheapest room in the market … For this segment, we have chosen to focus on giving a good infrastructure to develop your own solutions based on your specific needs.
The Disaster Recovery represents the set of technological measures that promote the recovery of data in times of emergency; thanks to a good disaster recovery plan that are able to ensure the protection of IT resources.
The moments of inactivity can be harmful without proper recovery plan. According to some studies, only 6% of companies lacking a plan of this kind will be able to maintain a certain balance and survive long-term. Without an adequate system of protection the consequences can be very unpleasant.
There are several causes that lead to data loss (UPS system failure, cyber attacks, IT equipment failure, human error), and many cannot be avoided.
In order to always ensure the maximum protection of your work and data, as well as the continuity of service for your online business, the company should implement a disaster recovery plan by making a risk analysis and by implementing specific solutions to manage any uncomfortable situation. In particular, we have identified five measures:
Considering these aspects becomes appropriate for the company that wants to implement a Disaster Recovery Service plan, contact our Sales Team for highly customizable Cloud Hosting DR solutions that can respond to different levels of criticality of the business.
More and more people are talk about this phenomenon that was even considered in the universities and then founded the CeFIRST, Centre for Educational Innovation and Social Research and Technological University Foundation INUIT which analyzes the so-called Big Data stating ‘IOT.
The Internet of Things represents a kind of neologism that refers to the extension of the Internet to the world of ordinary objects and places concrete essentially end up acquiring a kind of artificial intelligence using the software and network connection.
From some investigations conducted by companies such as Gartner and Cisco, it has emerged that individuals agree that within the next five years, all the everyday objects connected to the network, are destined to become a true reality.
The data show that by 2020, connected devices will reach to touch the figure of 26 billion, a number significantly is higher than the current of tablets, smartphones and laptops. The Internet of Things will affect many aspects of our daily lives and many, over time, will change.
Among them if they can identify some of them:
According to recent studies conducted by Cisco, seems to assert the idea that the phenomenon of the Internet of Things will have an impact that will be much more impressive and higher than what the internet was decades ago. This phenomenon will completely transform the world of things around us and the way in which humans interact with technology, once again we can re-confirm that the technology can be considered as a kind of extension of the body.
In this case it is natural to expect that the popular smartphone, with a simple command, will make even the coffee in the future!
Virtualized servers are not yet a Software Defined Data Center (SDDC). But shows where the journey is going: full decoupling of the applications from their physical basis at all infrastructure levels – with the aim of a comprehensive automation in the data center. But is still open, in what way from the SDDC vision to become a reality.
Reduced to a simple formula, the Software Defined Data Center expands the idea of server virtualization that will affect all layers of infrastructure in the data center service providers: Similar to virtual machines advance in SDDC network, storage and security to pure services that are largely independent from the underlying hardware.
The consistent service orientation provides a logical separation of operational from the physical infrastructure level – and so lays the foundation for a complete automation of the entire IT operation. In addition, to cost and flexibility advantages of SDDC can develop only if the IT organization a change is taking place: away from siloorientierten roles, towards a task distribution which is more closely aligned with continuous service processes.
Good reasons for SDDC
An obvious advantage of the SDDC-vision arises from the speed, can be provided with the new services. The deployment process is itself through self-service portals with stored templates that can be fully automated to billing of all services used.
For companies, this means two things: Firstly, new applications can be implemented within the shortest possible time – just as fast are business processes to new customizable requirements.
Second, the adaptability of IT is associated with substantial cost transparency: In SDDC IT costs of each individual business process is an accurate picture. The future capacity requirements can be planned ahead – IT investments thus obtain a more informed basis for decision.
Cost effects across the data center
Cost effects, as they are known from virtual server farms forth, extend SDDC on the entire data center. The abstraction of the hardware layer has, in particular, means that there is no single component, exclusively serving only one service.
Whether dedicated hosting servers, storage, network or firewall – the infrastructure sectors in SDDC form across pools of resources available to each service in the same manner. Is thus correspondingly high rate of utilization of the physical components, which in turn pulls a sustainable reduced hardware investment needs.
Moreover, going capacity expansion without costly migration projects. Long overtime for the copying of various databases with subsequent adjustment of application configurations belong to SDDC in the past.
The IT staff can instead deal with substantial improvements in the IT landscape. Finally, the hardware independence of applications and databases always implies, of course, vendor independence – this should not remain without influence on pricing in future procurements.
What is a software defined network?
Currently can essentially distinguish five different tendencies: The first, classic SDN approach separates the application from the transport plane by an interlayered control layer. From here, the communication is carried upwards in the direction of the application of a so-called northbound interface, and downwardly to the transport layer of a corresponding southbound interface.
The classic SDN model is currently used mostly only in special environments – are characterized by an application monoculture – such as Google’s data centers.
The advantage: SDN-like services can be relatively quickly implemented, and existing LAN infrastructures are largely re-used. However, the question remains whether with manufacturer APIs centralized control is indeed possible – especially as the control still remains in the transport layer.
The third, hybrid SDN approach combines the first two versions and is currently favored by most major manufacturers. The transport layer retains this while their own intelligence, but can also be controlled by a central controller. In the fourth approach, which is called virtual overlay, provides a virtual controller all network functions – where the data from the controller to a tunnel passes.
Rethinking of the IT department
Recommended instead are virtual teams whose members come from various infrastructure sectors and are firmly integrated into the daily business. The only way is to ensure a close practical relevance. Virtual teamwork also promotes communication skills – the skills that made wins an essential role in the service delivery to departments in the SDDC.
What technological SDDC approaches in individual cases are useful – this can only be determined on the basis of a detailed survey of existing IT infrastructure and a subsequent foot ends evaluation of their technological development prospects. Parallel to this SDN and in turn highly differentiated market trends in the area of SDDS are considered.
Although there may be at the present time no general recipes can be derived nevertheless the general council with a view to SDN that every now procured via network component manufacturer API or controller interface should be accessible. Besides: The SDDC transform fundamentally changed the way how IT is deployed and used in the company. The new On-Demand IT brings to IT departments in this respect entirely new organizational challenges.
Companies that think about moving their websites or applications to cloud computing, think about the most important part and that is security issue. But not everyone knows that selection of cloud services can improve the level of protection of their data. As it turns out in practice, the provider offers a higher security level than the one that you can provide within your own infrastructure. The fact is that, the solution of problems is related to security and the service providers. Serving businesses with a turnover of billions of dollars, cloud providers are doing their utmost to ensure the safest possible environment. Nevertheless, cloud computing are a host of new risks to potential users.
Before you trust cloud hosting service providers in India, you should make sure that you really ensure a level of reliability required for the safe handling of applications and data storage in the cloud. Fortunately, the increasing competition in the market of cloud computing services has improved the level of service for the users that is more flexible and provides organizations with the best security for cloud computing services.
But before we dive into cloud computing, the client must define a complete list of requirements for the computing platform, including the level of security. In this case, you can ask your question, and ask for the platform that meets your requirements. In order to not make the wrong choice, it is important to decide the questions and ask for the satisfactory answers that you are looking from the provider.
Who is on your side?
To date, the best experts in the field of security is cloud computing security Alliance (CSA). This organization has produced a guidance, including a description of hundreds of recommendations that should be taken into account when assessing the risks of cloud computing. The manual includes 76 pages, but you don’t need to read this document because we have selected the most important recommendations and tried to make a series of questions that a potential provider of cloud computing services should be asked in the first place.
Cloud computing: Questions and Answers
The following points are key questions that you need to ask the cloud computing service provider whose services you plan to use.
Each issue is one of six specific areas, as shown in Figure.
Before addressing the issues you must understand the benefits of using the solutions that are based on standards. And this applies to all areas of security. Proprietary systems are less trustworthy than systems based on standards, as the market players, government agencies, and standards bodies agree with this. That is why the widespread Advanced Encryption Standard (AES) and Transport Layer Security (TLS) have implemented such standards. They have undergone years of analysis and improvement. Moreover, using standards-based security system, the customer receives an additional advantage – if necessary, the customer will be able to change the service provider, as most service providers support the standardized solution.
Another thing that stands clear: how to make sure that the provider performs the data they promise? This will help you to conclude the Service Level Agreement (SLA), or contract on a written document, which will be clearly stated commitment by the cloud service provider. Thus, a series of questions from general to specific, that you need to ask potential providers of cloud computing services, begins here.
1. Preservation of stored data.
Does the service provider ensure the safety of stored data?
The best measure of protection located in the data warehouse is the use of encryption technology. The provider should always encrypt the customer information stored on their servers for preventing unauthorized access. The provider must also permanently delete the data when they are no longer needed and not required in the future.
2. Protecting data in transit.
How a cloud service provider ensures data integrity during transmission (within the clouds and on the way from / to the cloud)?
Transmitted data must always be encrypted and available for the user after authentication. This approach ensures that data is not changed or read by any person, even if it is accessible to them through unreliable nodes in the network. Mentioned technologies were developed during the “thousand person-years led to the establishment of reliable protocols and algorithms (such as TLS, IPsec and AES). Providers should use these protocols, rather than inventing their own.
Does a provider know the authenticity of the client?
The most common method of authentication is password protected. However, service providers offer higher reliability, more powerful tools, such as certificates and tokens to their customers. Along with the use of more reliable means to breaking the authentication, providers must be able to work with standards like LDAP and SAML. This is to ensure interaction with the system provider’s user identification and authorization of the client in determining the powers that are granted to the user.
Worst-case scenario – when a customer of the ISP is in the concrete list of authorized users. Typically, in this case, when an employee leaves or is moved to another position may be difficult.
4. Isolation of users.
How data and applications are separated from one customer data and applications from other clients?
Best option: when each client uses an individual Virtual Machine (VM) and virtual network. Separation between the VM and, consequently, between the users, provides a hypervisor. Virtual networks, in turn, are deployed by using standard technologies such as VLAN (Virtual Local Area Network), VPLS (Virtual Private LAN Service) and VPN (Virtual Private Network).
Some providers put data from all clients into a single software environment and due to changes in its code, it try to isolate the customer data from each other. This approach is reckless and unreliable. First, an attacker could find a breach in a non-standard code that will allow him to gain access to data that should not be seen. Second, the error in the code can lead to what one customer accidentally “see” in others data. Therefore, to distinguish between user data, use different virtual machines and virtual networks for a smart move.
5. Legal and regulatory matters.
How the providers apply laws and regulations that are applicable to cloud computing?
Depending on the jurisdiction, laws, rules, and any special provisions may vary. For example, they may prohibit the export of data, require the use of well-defined measures of protection, the availability of compatibility with certain standards and the availability of auditing capabilities. Ultimately, they may require, if necessary, it could be access to government agencies and the courts information. Negligent treatment from the provider to these points may cause its customers a significant costs arising from legal consequences.
The provider is obliged to follow strict rules and stick to a single strategy in the legal and regulatory sectors. This concerns the security of user data, export compliance, auditing, retention, and deletion of data, as well as disclosure of information (this is especially true when a single physical server can store multiple clients). To find out, customers are urged to seek help from professionals, who will study the matter thoroughly.
6. The reaction to the incident.
How provider does responds to the incident, and how much is the involvement in the incident of clients?
Sometimes, not everything goes according to plan. Therefore, service providers are required to adhere to specific rules of conduct in the event of unforeseen circumstances. These rules should be documented. Providers must focus on identifying incidents and minimize their consequences, informing users about the current situation. Ideally, they should regularly provide users with information from the highest level of detail on the issue. In addition, clients themselves must assess the likelihood of problems related to safety and take appropriate action.
The Future of cloud computing security
Despite the fact that today we have a much broader set of tools for security than ever before, the work is far from over. In some cases, to bring to market a technology that helps to solve a new task takes time, even though it had already developed. Here are some of the latest technologies: the data with built-in (Intrinsically Safe Data) and trusted monitors.
Intrinsically Safe Data (self-protected data) – it’s encrypted data, which is integrated with security mechanism. Such mechanism includes a set of rules which may or may not meet the environment in which there is intrinsically safe data. When you try to access the data, the mechanism checks on for safety and disclose them only if the environment is safe.
Trusted Monitor – this software is installed on the provider’s cloud server hosting. It allows you to observe the actions of the provider and send the results to the user who can make sure that the company operates in accordance with the regulations.
When all the research and development of new technologies will be completed, the next step is to implement the service provider. When this happens, customers will be with great confidence that refers to the concept of cloud computing.
SAP (System Application Programming) – A type of programming that is to develop applications that interact with the system software (operating system), or computer hardware. The main difference between system programming compared to application programming is that, application software is designed for end users (eg, word processors, graphic editors), while the resulting system programming are programs that cater to the hardware or operating system (such as defragmenting the disk) which causes a significant dependence of this type of software from hardware. It should be noted that the “normal” applications can be used in the work code fragments characteristic of system software, and vice versa; so there is no clear boundary between application and system programming. Since different operating systems differ both interior architecture and ways to interact with the hardware and software, the principles of system software for different operating systems are different. Therefore, the development of applications that carry out the same actions on different operating systems may differ.
In general, system programming has following characteristics (one or more):
Programmer must take into account the peculiarities of the operating system and / or hardware, which is supposed to run the program, and use these features (for example, using optimized algorithms for a particular architecture).
Commonly used low-level programming languages or dialects are:
Adjustment can be tricky if you cannot run the program in debug mode due to limitations in resources. The program in the simulated environment can reduce this problem.
System programming is significantly different from application programming, forcing programmers to specialize in one of these areas.
For system programming, it is often available only to a limited number of tools. Establishing sometimes has a high complexity. Library of the implementation period, if not available, are much less likely, and make fewer checks for errors. Because of these limitations, often used monitoring and data logging, operating systems must be equipped with very high-quality data recording subsystems.
First, the system programmers were certainly used as a assembler. Experiments with support for hardware in high-level programming languages done in the late 60′s led to the emergence of languages like BLISS and BCPL, but C, which has helped the growth of Unix, become widespread in the 1980s. Recently found some use for Embedded C + + , for example, in the I / O drivers in Mac OS X system.
Examples of software developed as a result of system programming is to implement major parts of the operating system, servers and applications for networking. For example, the development of virtual memory or drivers for the operating system.
