In fact, there are three main approaches to virtualization:
Server Consolidation – Have To Build A Cluster
From the point of view of server consolidation, we want to reduce our infrastructure costs, energy consumption, the system administrator in banks. Collect a bunch of unnecessary resources, release it, move applications to a virtual environment, and they’re great. In principle, it is most commonly found in my practice approach when collecting applications, virtualize and it is wonderful with this when goes live. The only drawback approach, not a disadvantage, but, well, the one thing that we need to consider is reliability. If we are virtualizing the dedicated servers, you have to put more than one machine, and cluster. For the simple reason that we have not hosted one application in this virtual environment, but they are a few dozen. And, if the machine we have dies, not just one service goes down, but a whole group. Therefore it is necessary to provide disaster recovery, because the business does not forgive unexpected downtime.
Cloud Computing Solutions Can Reduce Downtime
The Main Task: To provide a large pool of resources. It’s no secret that there are complex, resource-intensive applications, servers, databases, and they are constantly demanding for resources. Continually buy more servers and migrate to them, business is not always ready to go at it. The more we obtain, the higher is the cost of migration from one equipment to another. It is much easier to build a hardware stack, which will allow you to add to the application or database resources as much as necessary. It may be noted that despite the implementation of this idea “resources as long as necessary”, we get an incomplete use of resources, for the simple reason that any application in its life cycle has a peak load. As applied to the banking industry, the end of the year – it’s just devouring huge resources, because of the annual reports to shareholders, the regulator, the calculation of financial results, it eats up a lot of resources. And, despite the wonderful possibilities of balancing resources, usually in practice, if we gave someone a particular application resources, then we back them and not take away, because that really is not necessary. Yet another aspect that there can be, which is present in server consolidation – is moving from one set of hardware to another. Heavy set of applications, this problem is more relevant than in the case of consolidation.
I can give you a practical example: We needed to upgrade the equipment for one of our databases, in principle, except for the time spent by administrators to deploy infrastructure for testing, some test runs, the transition itself took a backup and restore all only in 6 hours. There was only one problem: on this basis, we had tied a customer service that we provide 24 x 7. And 6 hours of downtime is not small enough for the loss of business and despite the fact that we did it and put in the estimated time, went smoothly. In the case of GRID-computing, in our down time, it would amount to a maximum of 10 minutes. And it would take this time to shut down a virtual machine on the same equipment and transfer-switch on the other. Agree that the time is not comparable.
The third area, which is interesting and important – is desktop virtualization. On the one hand, in terms of infrastructure support, the decision itself is wonderful. Unhappy support specialists workstations stop constantly that are running around in the office, deal with applications in the field, with the problems and go in the console. Again, gathering in a virtual environment workstations, we reduce the risks of information leakage. It’s no secret that there are many ways to carry out a local station. Here, we can more clearly and more tightly control the resources available, to restrict the user’s ability to put a device in the workstation and something to try to merge… and so on and so forth. Here, one of the limitations is that the cost of server resources allocated for virtualization, while more expensive than buying the workstation. In my opinion, the price difference is still not large enough to interest the business. Because we still do a miscalculation of the project, and that is what comes out, unfortunately.
Limitations Of Virtualization – Licensing
I also want to address the issue of the limitations of virtualization, because it is actually having a lot of solutions and solutions are great, but they do have some of the shortcomings in my mind. In one of the projects we faced with the fact that since the beginning of something we virtualized, and then carefully re-read the license agreement with the vendor had to just buy the equipment, software and put back to use. Although there are various partnerships that avoid such conflicts. The next thing that we faced in their practice, this means all sorts of application security: hardware tokens and so on. Have to buy new hardware, additional software licenses that it was supported in a virtual environment, and this should be taken into account in the calculation of the project.
Pay Attention To The Order To Launch Applications
Pre-loaded application, I have already said, it is the another aspect that also need to pay attention – IT infrastructure services. The first urge: administrators sometimes put them in first place in a virtual environment, but then it turns out that it is not always a good thing. In case of any outages, failure make the things out of order and we have to start again to start our infrastructure.
According to studies conducted by research team, India is the country that has more interest in cloud computing when compared with other countries. Currently, 18% of medium and large companies already use some applications on cloud computing.
By the end of 2013, this share should jump 30% to 35%, that number is about 60% larger than the current base. Elsewhere in foreign countires, 14.5% of companies have or plan to have some kind of application.
“Cloud is no longer a hype” said Mr. Piyush Somani, MD and CEO of ESDS Software Solution Pvt. Ltd. “About 98% of companies consulted believe that this technology is here to stay, although there are many concerns about security and pricing”, he said. In India, between 45% and 55% of medium and large companies already use some cloud service.
In some foreign countries, the number is between 35% and 40%.
Analyzing the global market, the research team estimates that companies are spending $ 10 billion in Private Cloud applications such as servers, storage and networking, for example.
The global spending on servers, networks and storage systems dedicated to Cloud market should reach $ 15 billion, a figure that represents 5% of total spending on technologies, which proves that this percentage will represent 25% of spending on technology by 2015 – ie a 5% increase per year over the next 4 years.
In India, 80% of investments will be directed to the implementation of environments that will be blend with the Public and Private Cloud Solutions.
The research also talks about cost reduction, the ability to pay for use and elasticity systems are among the attributes most valued by IT areas in India when asked about the expected benefits of a Cloud environment.
The lack of governance practices and metrics that reveal the actual costs of IT environments is the main point to be evaluated in the Cloud market.
Few companies have, in fact, the tools and indicators needed to know in depth cost and criticality of each application or IT service.
In a scenario where the hardware is increasingly inexpensive and licensing models changing rapidly, it is imperative that new components are added to the equations of IT value, to take into account more components linked to business (such as service levels, capacity response and opportunity cost) and not only those related to IT assets (such as the cost of hardware and software) and the old practice of calculating income versus expenses.
The research analyzes the evolution of cloud computing and cloud hosting market since the beginning of business and follows the main challenges faced by CEOs. Currently 85% are investing in the operation of resources and only 15% on innovation. The ideal would be to have at least 30% to the area of innovation.
Cloud-based PaaS has been on the crest of a wave lately and will probably start to see vertical PaaS offers as soon as companies realize the potential impact in accelerating the development of applications. So to continue to expand this idea why not talk about Big Data PaaS?
How many agree that Big Data was originally driven by the need for discovery, rather than a real request of the companies. Ok, there are many practical examples of the use of Hadoop framework in operational applications, but many of these applications were born because of initiatives and to discover hidden underground.
If we are going to support the scientists and their counterparts in the data, it consists of application developers in an even more experimental enterprise environment, data-driven, rather we should put attention to the root of the Hadoop framework. Provide companies a way to build their internal applications using Hadoop building blocks that will require the talent of a well-oiled team. Ideally, the existing staff need to be trained and equipped with simple application development environments that support the use of unstructured data technologies.
With a deployment inside of a Big Data PaaS, the organization has a full stack which is not too dissimilar from Cloud Era, but perhaps with an interesting difference.
Sellers Based On Hadoop
The first could be compared to IaaS providers in the world of Cloud Hosting. The vendors were more focused on infrastructure and less on development of applications. Difference with a PaaS is that, it includes a comprehensive suite of services for the development team and a robust API that can be extended when services are developed and added to the platform. May include a number of other services centered on the application, such as:
The ultimate goal? Abstracted infrastructure, and increase time-to-market new business applications.
This Knowledgebase will provide you some tips about the factors you should consider when hiring a Cloud computing service, notes and draw the best out of them so they do not waste your time or money in hiring the web services that are inadequate.
Why Is It important to use Cloud Servers ?
Perhaps you’re thinking of accessing Cloud Servers services to deploy your applications in the cloud, then we will let you through a brief review of the implications of the use of a cloud service like hosting , before you can choose a specific service.
Using the cloud does not mean having a high knowledge in system administration, but must take the practice of some of the following tasks into account.
Items To Keep In Mind To Use Cloud Servers
The Autoscaling Of Resources
One of the main advantages of cloud services is that we can scale our virtual machines as needed. We have no need for an initial outlay of a number of machines.
As you increase demand and traffic start to increase, in this same way we gradually increase the resources we need, the most important thing is to take into account how they have autoscaling systems on the service platform you choose, there are alternatives that develop autoscaling transparently while others need to define a number of configurations to allocate the necessary resources.
You Pay Only For The Resources You Use
When you try Cloud Servers, all you pay your bills are for the resources you consume, ie you only pay for the use you give to machines, obviously payment are included for different types resource you use, from small machines or micro instance, to large or extra large instance machines, which have the added processing power and storage.
The value will also vary depending on the time during which process has been consumed, the memory used, the number of requests that have been conducted, among others, in order, a number of variables that must be controlled.
Additional Services Of a Cloud Infrastructure
Cloud services include not only services of web hosting, there are some hosting companies that offer additional services such as servers, email, databases already installed, among others. You must take into account the need for a complete solution as an important factor in choosing a web service or another.
Management Tools And Monitoring
All virtual machines are managed remotely, why, the more usable the tool is available, much better, many hosting services offer panels that monitor the operation of our machines and thus reveal when it’s time to increase our number of resources.
Now you know, you can choose Cloud Servers or any other service that suits your needs, Successes!
