Steps to consider before you plan your Cloud Migration
Unless you’ve been living under a rock for the better part of the last decade, you probably already know what a cloud is. Physical data storage for an organization in hard drives and similar devices are cumbersome and redundant. Coupled with this, is the ever-increasing demand for data storage. We now have a situation where a lot of capital and human resources are spent on this menial task. So, it is not really rocket-science that more and more companies are planning their cloud migration day by day.
Gartner tells us that virtual machines, in the form of IaaS and PaaS, will dominate the industry by 2020. And, the revenue for the same is expected to exceed $55 billion. Cloud computing is set to become the leading IT sector, and so it’s imperative that you migrate to the cloud, if you haven’t already.
This usually means migrating to a cloud service provider like AWS, Azure or KCloud. Here are some of the factors that you’ve got to consider.
Check if your SAP system is compatible.
Systems tend to differ in their compatibility with the various cloud services available. It’s really important to check this compatibility and choose accordingly.
Is the cloud big enough?
The cost of the cloud services depends on the size of the data. Therefore, make sure you analyse the requirements your organization might have, and pick the right size.
How far away from the cloud are you?
Cloud is present in almost every continent – the Americas, Asia and Europe. Therefore, pick a cloud keeping in mind the geographic diversity as well.
Choose a service that’s applicable to you.
Entry level services provide just a basic framework for the migration. Development services provide support from the beginning of the process until the moment it goes live. On the other hand, full services provide constant support and offer the best system management.
Plan and budget the migration.
Spend some resources to map out a well-thought plan. Make sure that the migration strategy makes the transition as smooth as possible.
Test and cleanse the data.
Sometimes the existing processes run on platforms incompatible with the cloud. Test the entire database out to identify these processes and change them. Also, cleanse the data. Weed out any irrelevant or corrupted data that would interfere with the migration. This goes a long way in simplifying the actual process.
The actual migration usually takes place in 6 steps, which are as follows.
- Analyse – A comprehensive breakdown of the current situation and the requirements of the system.
- Design – Design the migration accordingly, because proper system design greatly increases the scope of the migration.
- Build – Build a proper infrastructure and a foundation upon which the migration takes place.
- Migration of non-PRD – Files other than PRD (Program Requirement Document) are migrated first to the cloud.
- Migration of PRD – After moving the non-PRD files, move the Program Requirement Document files to the cloud
- Run – The actual runtime of the cloud services. Constant support and maintenance should be provided to ensure smooth operation.
