Cloud hosting services: cloud computing means many things, but most definitions include several basic value propositions such as scalable resources on demand, a pay per use billing model, controlled through Internet access and infrastructure management and optimization better than most traditional data centers.
At a conceptual level, cloud computing abstraction relegates all the computing tasks undifferentiated. Most companies do not offer any added value to customers or create any competitive advantage when they buy, create, configure and manage servers and storage. This can be seen even more clearly in the case of computer data recovery and data centers.
Conversely, poor performance on these tasks may involve a loss of value and competitive advantage. While these tasks do not involve any benefit, but is priced them wrong. It is like the opposite of a call option on the stock market: there is a high risk of damage, but there is potential for profit.
For companies planning to create its first data center for emergency recovery, with decision making that entails, the creation and maintenance tasks for servers, storage and networking tasks, cloud computing seems a clear choice. They can transform the capital expenditure that serves not to acquire any added value for operating cost without compromise that will probably get some best practices in this regard of which they could carry them.
Solutions are beginning to emerge around this idea of recovering data in the cloud or you can say Disaster Recovery in the Cloud or DR as a Service. The name is somewhat optimistic, because most of the products currently offered are solutions of traditional backup, with little or no ability to actually recover data in the cloud. Although many industry suppliers of backups are announcing their cloud computing offering, mainly just are offering users to store backups in the cloud. To earn the designation in the industry in the industry for data recovery in the cloud, the solution should have the following features.
The possibility of recovering workloads in the cloud
The cloud can offer more than a place to leave our backup files. It may offer the necessary IT systems to run our records retrieved, and, after the failure of a production system, the ability to quickly restart a complete replacement to data, applications and complete configuration in the cloud.
Real unlimited scalability with reduced or zero initial provisioning
A few providers can offer a quick recovery from a distance but really cannot be named “in the cloud” unless offered a large reserve capacity, without limitation or initial configuration. Although it seems a lot to ask, this is the premise of cloud computing.
Pay per use model
One of the defining characteristics of cloud computing is that you only pay for what you use. Use a bit this week and pay a little, if you use a lot next week, you pay more, but only for that specific week only.
The infrastructure will be safer and more reliable than you could create yourselves
When you decided to outsource any part of your activities, you are concerned about the safety and reliability of your supplier. The best cloud provider not only has the largest scale equipment, but also experienced in a large scale data handling. This means they can offer you much better security and reliability than any of its rivals, and their data center is better than you could create yourselves.
Comprehensive, automated recovery
Non expert users should be able to recover everything they need. This is the extra icing on the cake because it makes everything so easy, nobody wants to have to go through “manual execution” of full data recovery procedure and bring in experts can be insufficient, and the manual implementation is probably outdated. Why not turn the book into a part of the automated system? Instead, we would simply press a button that said “retrieve now”; wait for the files being copied, and then log on to the system that is fully up and running directly into the cloud. .
In short, the problem of backup solutions is that they are really traditional centric and leaves the data on tape or disk (and now in cloud storage) and perhaps restore back to the original hardware. If you need to recover to dissimilar hardware or to a different Virtualization platform, this usually does not help much with the inevitable incompatibilities. As relevant to equipment failures, you really need to have backup hardware.
So while “Cloud computing” means many things, you can say that any client that does not get the above five essential features in the cloud based disaster recovery solution will be disappointed and it is not worth it.
