You cannot generalize and list principles, when the discussion revolves around migrating to cloud computing. As a company you need to assess the kind of cloud computing setup that suits your organization. And as the CIO, you want to give up the headache of managing hardware. Management costs occupy a large portion of an enterprise's IT budget and migrating to cloud computing, helps to reduce such costs. So here are a few tips to make the migration to cloud computing easier:
1. Choose the right vendor for your family jewels
Choose your cloud computing service provider carefully. You need to assess your vendor's capabilities. Go with vendors who have significant market reputation or vendors you have had long established relationships with. Preferably choose vendors you have already worked with. This way you will be able to assess their capabilities in terms of providing cloud computing services that suit your enterprise. It also makes it easier while migrating to cloud computing.
2. Understand the service level agreement (SLA) on offer, and how it impacts your existing processes
SLA flexibility depends on your vendor rather than on the technology. SLAs can impact your existing infrastructure too. SLAs for cloud computing services are basically performance centric, since all you are concerned about is whether your cloud is up and running.
3. Multiple tenancy - Not a problem!
Multi-tenancy is a concern if your vendor's cloud is not big enough to handle your load along with other tenants (who might take up a lot of resources). This could be handled by choosing large clouds while migrating to cloud computing. Further, multi-tenancy has been around since the days of the mainframe. So it is not new, and it's now possible to wall off each individual tenant because most clouds have implicit walling. This prevents data leakage and mix-ups.
4. Explore options to handle security concerns on the cloud
Data security is an area that has not been explored much when it comes to cloud computing. So the security concerns are understandable. Despite the concerns, there are some things you can check with your vendor before migrating to cloud computing. For example, it is possible to check if your vendor is certified, when it comes to providing resilient firewalls.
Today' there are many options for the Indian organization when it comes to migrating towards cloud computing. You as an organization need to assess which model fits your organization best. For example, you could choose the option of migrating to cloud computing in phases. Put the less vulnerable processes first onto the cloud. Again, the key to a successful cloud computing migration is to choose a model that suits your enterprise.
