That’s what a paradox: on the one hand, is widely understood that the Indian IT market peak calls (“hype“) about the clouds came in the last year and since then the issue is clearly slowed down, but on the other hand, experts are not less confident, they note that the actual process of practical development of cloud models in our country is at a very early stage, the real things and really serious discussion has actually come.
Indeed, in recent years, VMware has not only retained the leading position in the field of virtualization (and many analysts have openly expressed their doubts as to whether it will succeed, when the field is left by whole team of IT giants led to Microsoft), but also led the movement toward the clouds.
IT world is now experiencing a phase of its global transformation in the direction of the widespread use of cloud computing, which takes place at three main levels – infrastructure, dedicated server applications and client solutions. However, this process takes place in the world is uneven: in front with a noticeable margin are the U.S. and Europe but particularly Asian countries (including India) lags behind.
The idea of cloud computing at the time (in the second half of “zero” years), first appeared in the form of public service, and only then began to spread on the implementation of internal IT infrastructure of enterprise private cloud model. Most IT vendors have long understood that this particular model of cloud technologies in the short historical perspective will dominate the IT market, and thus build their business development strategy and sets of proposals. Market surveys show overall correctness of such predictions: most cloud solutions implemented in the particular embodiment of the cloud (54%), 24% – in public, 22% in the hybrid (mixed).
It also noted the importance of “education” on the market: a noticeable obstacle to the introduction of cloud computing solutions are still existing on the market, the association of clouds with the use of public services, lack of understanding of the importance and possibilities of private cloud infrastructures.
But progress cannot be stopped, and more and more Indian companies like ESDS are beginning to look closely and has already innovated solutions like eNlight Cloud today. In this case we are talking about the “communal” model of cloud computing, where IT resources are extensive, but still limited the composition of consumers and at the same rates for services to a large extent governed by the lead authority.
In times when even small companies have produced a large volume of data, a new focus on enterprise storage systems: where and how to provide data on safety, without spending lots of money and without having to maintain a huge data center ?
Who relies on storing information to see your business evolve knows the importance of a high-performance database which is prepared for disaster recovery in the center of critical operations of the company. After all, the intelligent management of ever-increasing amounts of information has proven to be increasingly important for IT managers.
One of the most popular storage architectures is the Storage Area Network (SAN). In short, it shares the data on servers that are on a network data storage. But there is one major impediment: the cost.
Much has been said about virtualization storage and has become fashionable, and for many, is the great “savior.” However, in the midst of all the guesses on the subject, it is common to see entrepreneurs out there who feel somewhat lost amid the concepts and proposals that are often complicated and time-consuming and perhaps provide unreliable solutions.
Join the possibility of storage virtualization and a reduced cost is something that has been highly sought. Virtualized environment has total control, and you can add or reduce resources according to demand. And several companies have already been involved in providing solutions such as HP, which has the P4000, among others.
The P4000 is a storage solution with network architecture based on Grid Storage, that is, the more equipment is acquired, the greater the performance and availability of the environment. Uses existing infrastructure on the client, avoid costly networking. It is ideal for environments with virtualization of servers and customers seeking the first SAN storage.
In short: A great idea. Because it’s possible to start small and grow as needed, making upgrades to increase capacity – you can get, for example, with 2.4TB and nodes (modules) of storage may be included on demand and increase effective immediately.
In addition, it supports many operating systems:
Windows Dedicated Server 2003 and 2008 (Hyper-V as well), Red Hat, Fedora, HP-UX (obvious), VMware, XenServer, and X Leopard OS.
So instead of worrying about the latent need storage of your company and how much it will cost, how it is done and what size job you have from there, you focus on managing data and enjoy the consequences with a single change in its strategy: reduction of administrative costs, increase employee productivity and access to accurate information in real time.
Cloud Computing today is very reminiscent to the real natural situation. We live on land with long-established IT infrastructure. And in the sky above us there is a cloud, which offer many benefits (which we confidently assure suppliers). But how to get up there, to enjoy all these benefits is not very clear. And it is not clear what to do with established infrastructure in the land: to pull it in some way to heaven or to leave where there is.
Indeed: as in practice to shift to Cloud, What approaches can be applied here ? The revolutionary (to tear down the old are not required, but the clouds is just a new move, specially made for them) or evolutionary (gradually moving back everything that is used today)? IT vendors give different answers to these questions, each with its own view of business strategy and existing portfolio of offerings. We dare say that most robust and versatile version of the company now offers a VMware.
It is worth recalling that the intention to develop its technology is towards the realization of the cloud concept is widely VMware announced in September last year. Since then, the word Cloud was constantly present in the company’s corporate materials. VMware representatives are almost exclusively conducted in the subject of virtualization. And it was clear: the domestic enterprises are, by and large, still only the first stage of development of these resources (phase of server consolidation). In this situation, “Cloud gave” a not very clear advantages, and most importantly – with an unknown road traffic to them could only confuse the audience.
But now, apparently, it’s time to start promoting the ideas of cloud in India. Even from the most superficial analysis of publications shows that the term “cloud” and “virtualization” relates closely related. But still need to keep in mind that these are two qualitatively different concepts: the first belongs to the category of the concept (the methodological approach to IT infrastructure) and the second – a particular technology, implementing specific IT projects in practice. It should be stressed that virtualization – this is not the only way of formation of cloud systems. In today’s theoretical understanding the prospects of Cloud Web Hosting is associated with the transition to the use in applications architecture (multitenancy), which actually requires a fairly radical alteration of the application software being used today, based on the model of “each holder of – your own copy of the program.”
The use of virtualization allows you to make the evolutionary transition from traditional circuit implementation of IT infrastructure (within the enterprise) to the Cloud by creating a environment-based model that is based on common hardware “(shared hardware multitenancy), when the tenants have their own copies of the application that while working in a common technical infrastructure. Fundamentally with the fact that the existing applications in this virtual environment are functioning without any of their changes.
But at the same time it is important to note that virtualization – is not just a way to use legacy software in solving the problem of building a more efficient IT infrastructure. The question of what kind of market share in the future will be cloudy model is open, but we can confidently say that about any 100% can not be considered. Likewise, you can ensure that a full transition of software developers use software architecture that does not happen even in the distant future. And if so, then it will be a key virtualization technology implementation of cloud model for applications.
The overall logic of the movement of customers in the virtual cloud is quite obvious and is implemented in two stages: first, the consolidation of hardware resources is performed by replacing physical servers to virtual, and then made the transition from virtual servers to the dynamic virtual IT infrastructure. Actually that’s the system, formed in the second stage, is already quite possible to consider the cloud: virtualization layer separating the application software from the physical environment, virtual machines can be moved in the hardware space, including external cloud (although, of course, everything is not so simple because you need to solve many issues, not so much technical as organizational and legal).
But the fact is that, the second stage of (which has fully implemented the system of vSphere 4) VMware is not going to stop.
In the context of this approach, it becomes clear that the VMware is one of the most promising players on the field of cloud application server.
The general approach to the construction of “happy cloud” is clear, and it must be said that VMware already has a representative set of technologies and solutions for implementing these ideas.
