In my last blog, we saw various definitions of Cloud computing, along with conclusive definition as per me. This content will give you a broader perspective of Cloud computing.
Cloud computing as briefed is a computing paradigm with virtual network of remote servers allowing users to store, process and access data; providing on-demand computational services with features like elasticity, scalability, security and redundancy.
Cloud symbol is used to represent an Internet in diagrams and flowcharts. Symbol represents a set of varied devices that are networked together. This is how originated a symbol of Cloud.
Cloud computing is an old concept, although its origin is still a stuff of dispute. Research says, this concept was first implemented in 90’s but its practice as an Elastic cloud started in 2006. Now it is a trend, invading other technologies and rapidly catering many businesses. ESDS Software Solutions Pvt. Ltd. One of the top cloud service providers in India launched cloud services in India in 2010.
Cloud, according to services offered is classified as Infrastructure as a service (IaaS), Platform as a service (PaaS), Software as a service (SaaS).
Types of Cloud services depending upon the application of it are Private, public, community and Hybrid Cloud.
Cloud computing is trending in numerous businesses like IT, Telecom, Health care sectors, Hospitality, Entertainment, eCommerce, Universities, etc. and it has many more areas to sprout in.
Many SMBs are adopting cloud due to its varied and efficient features like Universal access, Cost savings, Flexibility, productivity, choice of customization, environmental and economic benefits.
With the growing popularity of Cloud Computing Solutions - Computing as a Service – business costs to launch new products, services or online platforms have been falling. Instead of large upfront investments in infrastructure, initiatives can begin modest and grow as needed. Thus, investment in personnel for the installation and support of this infrastructure also tends to fall. This means a decrease in the number of jobs IT ? Not necessarily.
Cloud Computing And The Labor Market
Unlike traditional IT architecture, which is based on number of servers (real or virtualized) running in data center infrastructure, Cloud Computing provides an abstract implementation platform, providing processing power, storage and transfer in accordance with the instant need. Many of installing, configuring, tuning and maintenance of servers are disappearing with the migration of applications to the cloud. As a result, some functions tend to be less sought after by companies, while others should gain space.
The Ups And Downs In Functions
Infrastructure specialists are the big losers with the migration of applications to the cloud. The ability to scale machines, configure settings, take care of the network and keep all this running is not worth much when it comes to cloud, as the focus shifts from hardware to software and data. Thus, the demand for these professionals should decrease, accentuating the trend that has already forming since when companies began to migrate internal infrastructure for outsourced data centers.
Other IT professional profiles, on the other hand, tend to gain space. According to Mashable, functions related to data analysis tend to suffer an increase in demand, as with the migration to the cloud undertakings switch sizing efforts, construction and infrastructure maintenance for areas related to its core business. Data mining, Web Analytics and Business Intelligence are the buzzwords of time in this area.
Specialists in software architecture and security must also gain space. Applications running in the cloud can have high availability, but this does not come for free: software architects play a crucial role in the design of new applications to take advantage of that. Also the security experts now have greater responsibility, because much of the data that were once comfortably behind firewalls in private networks, is now in the cloud. Work to secure data increases and, consequently, the importance of these experts to the organization.
Rearrangement In The Market
Like any change, migration of applications to the cloud will cause others in the IT job market, but hardly mean decrease in the total number of jobs in the area. What should happen is an internal rearrangement, with some functions gaining importance and jobs and other losing importance and space. It is for the IT professional be aware of these changes and acquire the necessary knowledge to keep your valued pass in the market, since computing as a service is a concept that is here to stay.
Cloud computing as a definition remains very controversial. When asked define cloud computing, definition is stated liable to a particular application with no unanimous definition, making it altogether vague. Let’s see below few definitions of Cloud computing to get a hint of it:
1) The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. This is an internet definition of Cloud computing.
2) Cloud computing is a computing term or metaphor that evolved in the late 2000s, based on utility and consumption of computing resources. Cloud computing involves deploying groups of remote servers and software networks that allow centralized data storage and online access to computer services or resources; says Wikipedia!
3) Whatis says Cloud computing a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).
4) Gartner group ‘A forecaster of Information technology’ defines cloud computing as a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using Internet technologies.
5) National Institute of Standards and Technology (NIST), which defines the standard, defines cloud computing as, a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.
6) The IEEE Standards Association (IEEE-SA) defines cloud computing in two working drafts. The P2301 (Cloud Profiles) draft highlights different ecosystem of cloud such as cloud vendors, service providers, and users. P2302 (Intercloud) draft provides definition on topology, functions, and governance for cloud-to-cloud interoperability and federation.
7) Short and snappy definition of Cloud computing from all the above definitions, concluded as per me is: A computing paradigm with virtual network of remote servers allowing users to store, process and access data, providing on-demand computational services with features like elasticity, scalability, security and redundancy is Cloud computing.

Pitch of cloud has been lately evolved to peaks. In coming years, cloud will acquire entirely new aspect. According to the Google trends, searches for ‘CLOUD’ are growing. Even though, in some business environments, comprehensive awareness about Cloud computing is mislaid.
Cloud can be adopted by any size of businesses. Although, it has certain challenges to bloom effectively, to fit in all sorts. Today’s challenges are tomorrow’s opportunities, as we say. Few important factors involved in cloud computing to make it more effective can be as below:
Availability is the key feature for selection of any cloud hosting service. It is degree of ability of a system to operate, i.e. to generate timely responses for the respective requests. It replicates the need of storage and servers. High availability is an important factor for modern cloud based applications and devices. It is a challenge for maintaining availability of a system by balancing the offset between other system parameters.
Scalability along with high availability is key factor in cloud hosting services;cloud should be auto scalable is the requirement of the day. However, this does not help in improving availability of the system. It’s important to maintain the tradeoff between availability and scalability in cloud computing.
Elasticity is the art of balancing load with cloud computing in real time. When the load is increasing, it must have ability to grow and with decreasing load, ability to shrink. It is important to maintain offset between scalability and elasticity.
For advancements in Cloud computing, different approaches are taken by cloud companies to stand out. This brings new challenges in catering valued services for clients. With latest research, cloud is adopted by varied sectors. It has catered sectors like Health care, Hospitality, Communications, Entertainment, eCommerce, Universities, etc.
Below are few extents where Cloud is budding with virtuous opportunities.
Heaps of data with lots of inequalities exists, in order to process and store this data first it must be organized, this prompts to data analysis, and then arises data processing and storage. In order to provide efficient data management as a service, system must be scalable and elastic.
Health Care organizations are widely adopting Cloud computing services providing with a significant level of comfort in organizational operations. This prompts to effective monitoring of sections with optimum resource utilization. Health care sectors need to carry large data, to which cloud computing provides very cost and resource efficient means of storage, process and access. Security threat is a vital challenge as Health care organizations carry very sensitive
Cloud has stepped in Hospitality fields these days. Hotels have to cart managing of the complete systems efficiently with lots of data as a result, to which management tries to fetch much secured, efficient and cost effective way for management. Cloud provides with very elastic and scalable utilization of resources in Hospitalization.
This just not ends up an opportunities and challenges associated with Cloud, It has raged so immensely in varied of application fields that one cannot cover up the whole stuff altogether. This is just tint of it; things are predicted to be much more colossal in coming days.
We can say, the day is not far when the earth will be covered with clouds.
There won’t be any soul in IT zone, which has not caught up anything allied with clouds. What is cloud? I am sure all of us, who heard very first about clouds (not the one, which we get, showers from) would have asked this question, isn’t it? Let me brief you about cloud/ cloud technology/ cloud computing. Cloud computing is a virtual network where one can store data, process data, and access data as in hard disks, it includes Infrastructure as a service, Platform as a service, Application as a service.
Cloud technology has lately touched altitudes in terms of providing cloud services in various business sectors and it is going to headway more in upcoming years. Clouds are classified as Private, Public and (mixture of both) Hybrid Clouds; and this does not put to an end in its range, many cloud service providers are heading towards customization of clouds for Business integration.
More or the less every cloud service providing company, delivers public and private cloud services also cloud customization with accords to the necessity of businesses. Private cloud is a cloud infrastructure functioned exclusively for one organization. Public cloud is a network with services that is open for public use, it can be free. Hybrid cloud is a composition of two or more clouds (Private or Public).
Its phase of ‘pay per’, we see pay per second in mobile services, pay per click in online advertising, pay per hour in cyber cafes, pay per dish, ride, movie, etc. and now ‘pay per consume’ in cloud computing, isn’t it sound good? Yes! Why to pay extra if you are consuming very less than what you are paying for it? Many cloud providers in India like Google, eNlight from ESDS, etc. are providing pay per consume service, which is a service efficient innovation in cloud services providing elastic cloud service. eNlight cloud provides scalability, pay per consume, cloud management, flexibility for clients very efficiently along with Exuberant Support.
Briefing all advantages, you get a complete customized solution provider for your cloud. You can save your unnecessary expenses spent on unused span of services and gain significant productivity in your Business!
More and more companies migrate to the cloud computing model. For the most part, seek to generate savings for organizations. In part, too, are concerned to have more efficient processes.
Just so, the different models of cloud, need to be evaluated carefully. When defining the cloud model to be adopted, the organization must be familiar with the differences and similarities between them, especially with regard to security aspect.
For example, the model SaaS (Software as a Service), designed to provide access to applications, groups and user policies which can only be used to ensure that certain users have access to selected information on organization’s CRM database.
In relation to the PaaS (Platform as a Service), whose main objective is data protection, is magnified when used in conjunction with virtual data storage, and in cases of unavailability of other cloud, it plans and calculate safety for balanced distribution of services for the platform at the time of any outages, and study of the appropriate encryption mode for account safety.
In the case of IaaS (Infrastructure as a Service) model, the CSO (Chief Security Officer) have to worry about arranging a corporate governance framework within which the transactions occur.
To assist CSOs to how to deal with different models, the following list enumerates challenges linked to each form of work in the cloud:
Challenge # 1: Protect personal information before transmitting them to the cloud. There are many laws and many policies that prevent sensitive data which is transmitted to third-party systems – such as the cloud case. So the very cloud providers suggest that packages with sensitive information is sent in encrypted form or is removed. At that time, the question arises on how to perform encryption or deletion of data before sending them to the provider.
It is known that the encryption process is an operation that consumes valuable CPU resources. An alternative for this is to hire a broker to do the encryption of data between workstations and the provider. Optimize confidential data identification process at the time of shipment.
Challenge # 2: No need to create hundreds of mirrors of sites in the cloud. There is no need to duplicate the data unnecessarily, large companies with thousands of employees all over the place have a dilemma that they need to create hundreds of mirrors of sites in the cloud.
The ability to allow access is based only on local platforms logins to ensure connection to the cloud-hosted services, eliminates this need. The problem increases when there are multiple credentials / passwords for each user. This situation generates significant costs and risks for companies and can thwart the organization. Just calculate the work involved in managing passwords for ten thousand different employees and anticipate that each of them forget the password at least once a year.
Enable single sign for local systems and the cloud platform can help you to mitigate associated risks and costs. After all, it is easier to remember just one password. It also generates less work for IT in time to stop a user from access – an operation will only make it impossible to login with such credentials in local platform and cloud.
Challenge # 3: Conduct audits and take cloud platform with on-demand contracts (pay as the cloud platform is used) means to deliver financial executives a form of control of investments. This tool is usually provided by the provider itself, but in cases of external audits or disputes with service providers, it is worth keeping monitoring indoors.
To account monitoring, companies can hire an intermediary, as proposed in the matter of data encryption (above). The service should actively monitor the allocation of resources and aid organizations to stay within the rules and regulations of governance.
Few technologies have had throughout history such a rapid acceptance among enterprises, including small and medium-sized (SMEs), as cloud computing. This model, which allows the use of different kinds of software as a service, is increasingly adopting facilitating innovation in companies and at the same time, enabling them to be more agile.
Cloud computing drives innovative attitudes within a company and, in some cases, can be considered as a first step to be a beneficial organizational culture of innovation. Companies of all sizes are increasingly taking business processes to the cloud.
This is because the new generation of business applications that run on cloud brings with it not only the flexibility needed by business lines (purchasing, HR, marketing, sales, etc.) to operate and turn, but also the integration that is necessary to automate and connect all the organization’s processes with each other. The cloud solutions boost efficiency, reduce costs and accelerate the adoption of technology trends such as mobility, data analysis (including real time) and big data.
Investing in a cloud solution adds new values to companies that can operate in real time, sharing information efficiently and securely between company employees. The agility and the ability to access real-time information are not just that cloud computing can provide.
Working in conjunction with other strategies, the use of cloud software brings the short and long term benefits such as greater analytical potential and agility in business application databases to add, compare and evaluate several possible scenarios and information within the company; access via mobile devices to detect changes, and share information with employees without thinking about their location.
The cost is also an important benefit that the cloud offers to the companies. Cloud computing allows companies to incorporate the latest innovations in the field of information technology without having to bear the extremely high software license acquisition costs and not to the implementation of an infrastructure (systems and hardware) specific to rotate applications. In this software acquisition system, are only subject to payment of a monthly fee for the specific applications being used and that are hosted on the cloud server.
Other Advantages: The solutions running in the cloud tend to be flexible enough to be configured according to the demands of each company in a very reasonable time. In addition, the cloud software interfaces are often similar to applications that people use every day on their smartphones or tablets. Therefore, no need to train staff to use the tool.
Finally, I highlight the cloud breaks a paradigm related to consumption by SMEs technology. The technology allows these companies to really focus on the conduct of its business and not worry about the acquisition and management of IT. It is also a pioneer in giving access to the latest innovations without having to fiercely consume budgets. So now that the market is more competitive than ever, SMBs can better compete with large companies.
You just have to add cloud in your business. What was once trend now shows a key tool for the growth of any organization.
What you’ll do? Wait a little longer and run the risk of leaving your competitors in front or anticipate them to be more agile, innovative and competitive?
Moving email in the cloud is one of the most crucial tasks businesses need to think about. Since, cloud computing services are new to most of the businesses, its necessary for them to understand the term “cloud computing”, services and its benefits to compete with their rivals using cloud services.
Often people describe the term “cloud computing” in many different ways. In simple words, cloud is a computing model which offers applications, software’s, storage and resources over a network (typically the Internet). Comparing virtualization and cloud, you will find that cloud expects world without barriers. It offers various benefits to all sized businesses, despite these facts businesses still have high concerns in regards to the security and privacy of data as well as the possible unavailability of the services offered by the providers that prevents access to the data.
In the market, there are four deployment models of cloud available that are private cloud, public cloud, hybrid cloud & community cloud. Each have its own characteristics and applicable to a different requirements.
Basically, a private cloud is used by an organization that requires more security and privacy. The organization has to bear the costs of control, support and building the private cloud infrastructure in their organization.
Public cloud is an ideal solution for SMBs, as it is cost-effective and most of the services and web-based applications rely on it such as voicemail, free email services, free social networks, and more.
The hybrid cloud is a model where the organization can make use of both private and public as per their requirements. Whereas, the community cloud is a deployment model which contains a number of companies that are known to each other and shares the cost of the infrastructure. The community is quite common in some market, where companies are of same group.
Market Share of Cloud Computing Technology
The cloud computing based cloud hosting services are considered as the best IT solutions of the 21st Century. In order to save green, reduce energy consumption, carbon emission, and to minimize the investments on the IT resources, most of the U.S. companies are are planning to adopt the cloud-based services. It is revealed from the study by Carbon Disclosure Project that the adoption rate will accelerate from 10% to 69% by 2020. It is also clear that Latin America is leading the adoption of cloud computing.
Despite the benefits, all the legal aspects like risks posed by cloud technology and the country where the data will be stored must be taken into account before implementing the cloud services.
One of the important reason for moving email in the cloud environment is the notable efficiency attained by this computational model. Many of the corporations doesn’t have users in hundreds and thousands nowadays. However, a cloud service provider has an ability to offer these services to millions of users at cost-effective rates. Furthermore, due to limited budgets it is common to have limited internal email storage, however, an email in the cloud doesn’t have such limits. Since, the cost is minimal and is determined per usage, even small and medium companies can afford greater storage capacity in much lower costs.
However, when it comes to migration of your corporate emails in the cloud, you need to be more careful as most of the businesses depends on their data, be it emails or any other kind of data. Considering the legal aspects, the cloud model which you are going to implement must be in legal compliance, adhering to the rules of the country where your data would be stored by the provider. The territorial issue is much much more important as you can easily take required actions against the company in an event of data loss.
Therefore, it is vital to give attention towards the small print of “Terms & Conditions” and “Service Level Agreement” before deciding to opt for the email in the cloud solution. Also, its customers responsibility to make sure that the cloud provider offers everything required and provide necessary guarantees and systems for security control. When moving email in the cloud various things like hidden costs, legal issues, security aspects must be considered and ensure that all the legal aspects are included in the terms and agreement print.
It seems that all organizations are analyzing what can be moved – or should be moved – to the cloud. However, the cloud is clearly not the answer for all; As with any technology, there are advantages and disadvantages. Thus, it is important that all professionals understand how and when the cloud is advantageous for their applications.
In the assessment and planning of migrating applications to the cloud process, the databases are usually the most difficult element to understand. Of course the data is the heart of every application, so it is essential to know how databases can function reliably in the cloud.
Here are some ideas and recommendations to keep in mind when thinking about moving databases to the cloud:
1. It All Starts With The Performance
If I had a penny every time you hear “the cloud is very slow for databases”, sure I would have enough to buy a double cappuccino. The uncertainty of the performance is the main concern that prevent traders to move their databases to cloud or virtualized environments. However, concern is often unjustified, since many applications have performance requirements which are easy to fit in a number of different architectures of cloud. The cloud technology evolved over the past three years and today already offers several deployment options for databases, some of them with very high performance capabilities.
2. Visibility Can Help
The easiest way to solve performance problems is putting a lot of hardware to run, but obviously this is not a good practice and it is not very profitable. A monitoring tool for database can help you understand the true requirements of the database and resources of your application. We can think about things like CPU, storage, memory, latency and throughput of storage (IOPS can deceive); planned growth requirements and backup storage; oscillation of resources based on peak usage or application in batch processes; dependency and connection data – beyond connectivity applications, there may be other requirements for data exchange between applications, backups or data stream input.
One advantage of the cloud is the ability to dynamically scale resources vertically or horizontally. So, instead of being a source of uncertainty concerns of the performance, it can really give you the peace of mind because the right amount of resources can be allocated to your applications to ensure proper performance. The key, however, is to know what those requirements are.
3. Take a Test Drive
One of the obvious benefits of the cloud is the low cost and accessibility. Even if you are not already developing a migration plan is a good idea to play with cloud databases to familiarize yourself, test and learn. In an hour of your time, you can put a database running in the cloud. Set it up, play a little and then throw away. The cost is minimal. With a little more time and a few rupees more, you can even move a copy of a production database to the cloud, testing, deployment options and learn how your application and the database will work in cloud.
4. Carefully Plan Your Deployment Model
The cloud offers several deployment options that should be considered. For example, the Database as a Service (DBaaS) offers simplicity in deployment, automation and a managed service. Leverage Infrastructure as a Service (IaaS) is an alternative to running instances of the database in cloud servers, which provides more control and that looks like a traditional physical deployment. There are also multiple storage options, including storage block units SSD , IOPS guaranteed, dedicated connections and optimized instances of databases. Cloud is primarily a shared environment, it is also important to understand and test the uniformity and variability of performance, not just the theoretical peak performance.
5. Take The Step
There is not a single migration plan covering all use cases. Instead of trying to use a formula to make the move to the cloud, I recommend talking to your cloud provider, explaining your environment and getting the proper guidance. In general, it is also a good idea to create a duplicate environment in the cloud and make sure it works well before changing the production application. And, beyond the requirements of recovery and data backup, is also important to consider the replication servers or waiting in a different region from which its major servers are.
6. Monitor And Optimize
As with deployments in place, it is important to monitor and optimize your cloud environment, then it is working. Optimization tools for database provide analysis of the waiting time, and the correlation of features can speed up database operations significantly, alert you when there are problems (before they become big problems), increase application performance and monitor resources to help with planning. The database administrators, developers and IT operations can benefit from a tool for performance analysis that enables them to write good code and identify the root cause of everything that might be leaving slow the database, as queries, event storage, server resources etc.
The cloud is evolving rapidly. It’s getting better, more reliable and more flexible all the time. As occurred five years ago, when most people could not imagine the transformation that would promote the cloud today, we should expect that technology continues to evolve at the same pace over the next five years. This is one more reason to start experiencing the cloud today. It is not just a journey that requires to break some paradigms and change your way of seeing things, but also a journey that can provide meaning to the applications and benefit at work.
The expression “Being in the Clouds” brings us comfort and a sense of superiority. Cloud computing – cloud hosting – is moving increasingly to a destination with no return: the consolidation as an essential tool for the future existence of the internet world.
According to a report recently published: “The cloud will be more important than the internet”. The perceptions we had about the internet in the 90s were minimal compared to what is available to us today. We believe that same will happen with cloud computing.
Cloud computing is already a reality
In a few years cloud computing will be essential for the continuity of the Internet itself as a whole.
The need for physical space, high energy costs and especially the ideology that we can have a better economy and technological harnessing idle resources to work with, will – and already do – that cloud computing is a global reality.
A survey conducted found that only 10% of the people interviewed were using cloud computing solutions, while in July this year the same question was asked and the number surprising: 66% of people interviewed already use cloud computing solutions. These numbers represent the power of evolution and impact of cloud computing for individuals and corporations around the globe.
Arguments in favor of the use of Cloud Computing
There are several lines of argumentative reasoning in defense of Cloud Computing, but all are consolidated on a few points:
Elasticity Demand: Unlike physical servers hiring, as there are already a pool of machines, ie, a structure of computers ready for use, cloud computing allows you to increase or decrease the resources of your server in seconds. Compared to dedicated servers, for example, this type of change could take hours, maybe even days;
Cost Savings: There is a better use of server resources, which, once working together, allow the full use of memory, processing, disk space, etc.
Speed: The more we enter the digital world, the more we realize that speed is critical for decision making, whether positive or negative. Everything in cloud computing is connected and allows immediate interaction, changes are applied at the time sent and a better use of time is also felt.
Basically cloud computing consolidates three major needs of our century technology: Autonomy with high agility and cost reduction, a phrase that everyone likes to hear!
