Subscribing to the Cloud and setting up your Cloud account is simple. You may even find using the service a pleasurable exercise. But, there are a number of issues you must address before you actually migrate your applications to the Cloud and sit back with a smile of satisfaction.

Remember Cloud interoperability is not just about application programming interfaces and virtual machine image format conversion protocols. It is all about moving your applications from private to public Clouds or vice versa.  You need to select the best of the breed Cloud technology and avoid the possibility of getting locked in with any one vendor system. You need tools that will facilitate communication between vendor systems and Cloud types.

First, Cloud vendors do not distinguish themselves on price alone. They decide upon the kind of hypervisors, storage and network models and tools they will use to optimize their Cloud and attract groups of customers.  They define the environment of operation and consequently limit the options available to the customer.

Secondly, application dependencies will determine whether or not the application can be migrated to the Cloud. Application migration will require reproduction or replacement of application dependencies in the Cloud including directory infrastructure, identity management, and database management. So, it may be possible only to migrate simple applications to the Cloud.

The good news is that a number of new solutions are emerging for application migration to the Cloud. These tools also promote interoperability between Clouds.

One approach to Cloud migration decouples the application and the underlying infrastructure to feed the virtual machine just what it wants to see. The process isolates the customer environment and protects it from any problems created by the vendor’s infrastructure. The customer does not have to modify anything.

Another approach is to recreate the customer environment in the target environment. However, the source and target machines must be binary compatible and the target machine must be configured with necessary drivers for the operating system that will run on the target server.

A third solution to the problem of migration creates Cloud bridges. The solution creates a bridge between the source and target machines and the applications running from the target machine appear to run from the source machine in a hybrid Cloud environment with no loss of security.
