Top challenges impeding enterprise cloud migration journey
Wednesday December 27, 2017, by Vijay Somanchi
If the business benefits of moving to the cloud are so real and outweigh the risks, why isn’t everyone doing it?
Enterprises in the race to modernize their infrastructure many find it difficult to reduce capital expenses and streamline operations while using on-premise SAP solutions. While migration to the public cloud provider like Azure may be a solution, many enterprises are holding back from the decision. As of late 2016, about a quarter of the organizations had not even begun the transition to the cloud. In this blog I’d like to go decode the way IT leaders across enterprises are looking at the transition, and make a case for how they should look towards the cloud.
The data security risks while migrating to the cloud
In my experience many traditional enterprise IT organizations are still concerned about storing production data in the public cloud due to lack of control on multiple disparate data repositories across different environments. 55% of respondents to a survey question on this said they were unconfident or only somewhat confident that they had mitigated their data security risks in the cloud. Despite this lack of assuredness, only around half the organizations work with a third party to protect these critical programs. To address this, ensuring third party support and strong internal protocols is the first step towards mitigating the primary risk associated with cloud migration. The partner can proactively prevent malicious attacks at all stages: processing, networking, transmission, storage, application security, and user access.
Handling Complexity of Architecture
I have seen that the chances of a failed cloud migration increase in proportion to the complexity or intricacy of the architecture. Failing to assess the complexity involved in the migration can lead to an unachievable migration plan that continuously gets pushed out. To avoid these risks, invest in effort estimation. For example at Brillio we apply the OptiMigrate framework which includes Cloud readiness assessment toolkit. It will help you plan for some of the easier migrations first to recognize early benefits and build confidence. It sets the right expectations with the business up front and saves you a lot of time, money and frustration.
The Insecurity of Data Gravity
Data Gravity is the situation where it becomes difficult to test if an application and its data work properly in the cloud, because most replication-based migration tools require data to be moved first, and then the application. If data becomes large enough it can become virtually impossible to move. To mitigate this, only use live migration approaches and tools that stream the whole instance. Live migration eliminates the need for complex system synchronization and thus avoids consistency issues.
Migrating to the cloud has many potential benefits, if you go in with open eyes and armed with knowledge and caution. There exist strategies to address these risks and unlock the true business potential of a migration from on-premise SAP to the Azure Public Cloud. It is simply a matter of careful planning and execution in collaboration with a responsive, capable partner.
