Currently, most companies see many advantages in virtualization. But not everyone can get you the most, and in some cases, is not the right solution. Or at least, not yet. Virtualization applications and evolve together, but still a long and exciting road left. Hence, the popularity of cloud computing should not in any way overshadow the real needs of a company.
The cloud hosting allows you to pay only for the resources used, and for this it is necessary to take continuous management thereof and to control so efficiently, spending. Virtualization is still implemented on the physical resources of a server intelligently configured to maximize performance, dynamic provisioning times and use virtual machines only for a few hours. The most illustrative example is a website that at peak times increases its views on a number much higher than usual such as Christmas, summer, one night … and you need twice the front to support all requests. Manage virtualized resources can lift machines much faster and for a particular use. So far, so good.
WHAT SHOULD NOT BE IN THE CLOUD
Thanks to a robust, configuring virtual machines cloud hosting can be adjusted fully to the needs of the client, but at all? If a customer has developed software that makes intensive use of CPU, as might be research applications requiring a lot of that resource, does not it make more sense to use a physical server, hosting traditional, for what was used before it came virtualization? Probably yes. Ie not set a hypervisor and use all the resources of that device for a particular application. Does this mean loss of scalability? Not necessarily: if management policies capacity are designed with the hosting provider, you can grow in a sustainable manner even with a physical server traditional hosting. The important thing is not to fall into the trap of wanting to virtualize the invirtualizable and pay the consequences malfunctions when in fact, every part of the solution needs something different.
The key is in mixed solutions with a part and a non-virtualized, cloud hosting and traditional hosting. There are ideal for virtualized services such as web front or development environments and integration, and there are also services that are more likely to require all the resources of a dedicated server, such as databases or remote access platforms. This does not mean you can not virtualized all or a dedicated server is the solution when standards are exceeded resources, it is necessary to know what each option today that best fits your application of business.
