Resistance and non-resistance to deploying cloud computing

In a tough economic climate, the most common phrase that C-level executives mention about it is "I'm already planning the cloud, so why don't we use the cloud instead of buying so many servers?" "The idea has become more common, but is the cloud really ready?" Usually a good engineer would say "look at the situation".

Not knowing when to start, the cloud has become recognized as an option to meet the advantages of Internet sites, hosted email, scalable storage and on-demand computing needs. Users who are already using the cloud to achieve these purposes say that when they need it, the cloud provides the computing power they need at a reasonable price. Cloud can help to complete projects faster, better deploy it for unpredictable network traffic, and better handle emergency emergencies. But while the advantages and achievements of cloud-based hosting services are so satisfying, the deployment of the cloud remains fraught with resistance and irresistible factors.

The cloud's resistance was initially from two aspects: IT managers accustomed to managing their own hardware devices and executives who feared that the cloud, the unknown, would cause insecurity to user data.

Both have the tacit belief that it would be safer if their servers were controlled or operated under their supervision. With the economy looking for a way out in a slump, compressed budgets and limited resources will force many it and business professionals to start experiencing the cloud for the first time and changing their traditional managed hosting patterns.

The question starts with the mixed cloud: is cloud computing really ready for everything? The answer is: maybe not, but everyone is ready.

Today, the cloud needs to meet your application and IT infrastructure. One important thing to keep in mind is that cloud computing is not an all-or-nothing concept. The cloud can be part of a large IT infrastructure strategy that includes internal data centers, collaborative positioning, or managed hosting.

In fact, hybrid cloud plus traditional infrastructure may be the best choice for most enterprise users. A hybrid approach can provide you with cost savings, scalable on-demand infrastructure, and the security you need.

When planning a hybrid cloud strategy, it is helpful to place applications in three areas: areas that require dedicated infrastructure, can be fully adapted to cloud applications, and the mix of cloud and dedicated infrastructure is a good idea.

Start by compiling your application list and try to divide them into three categories. Remember: This is not an all-or-nothing concept; a single application can cover both a dedicated and a cloud infrastructure.

Services that require a high level of security or a large capacity database should now remain on the dedicated infrastructure. Common or up-scaling and down-scaling have unpredictable applications that are the object of choice for the cloud. Then the application software in both. Here are some application software and their possible classifications:

Applications that can now be hosted on the cloud:

-Corporate blogs and Support Wiki
-Instant Messaging or email
-Brochure site containing company products and brands
-Test/Development server frequently used by developers every day
-For e-mail archiving, backup, log data storage
-Minimal remote disaster recovery capability
-The latest applications that are still in the research and development phase or ready for testing

Application software that may require dedicated infrastructure:

-erp
-Enterprise Database
-Credit card processing services
-source code of the National Atomic Arsenal
-Storage of latest clandestine research and development projects
-Need to use the specified hardware or operating system software that is not available on the cloud

Here we ignore the hybrid classification, because it is most difficult to generalize this classification. Also realize that this classification may be the most flexible. In each it enterprise, there may be dozens of or even hundreds of applications benefiting from the traditional infrastructure and cloud blending patterns.

So how do you use the cloud to build these hybrid solutions? It's difficult when the cloud is 2000 miles away, and you're trying to solve a physical problem. If your cloud is too far away, a hybrid strategy may be constrained by application software that uses the cloud for batch processing. You can also use cloud storage, which is not sensitive to latency, or you can do a local cache of data.

But there is already a better mix of solutions available on the market. Providers that provide the cloud and complement the traditional infrastructure within the same datacenter can open up more choices for users than simple cloud providers. Imagine how cloud is connected to your physical server through Gigabit Ethernet instead of the Internet. The flexibility of this type of hybrid solution is greatest, and as a promising approach, a hybrid solution can take full advantage of computing power as a service.

Without other factors, the current financial pressures are stimulating innovation, and companies are suddenly happy to try new things. If you are making changes to your infrastructure strategy, consider this hybrid cloud solution. It can solve a lot of financial problems and help you keep growing in a depressed economy.

Most companies still manage their data in a traditional way. No one will move all the business to the cloud. But with the change of corporate climate, we will see more enterprises and IT professionals to accept the cloud, overcome difficulties, to a more solid start cloud forward.
