If you do a quick Google search of “cloud migration best practices” you will find pages upon pages of articles and blogs that outline reasons to migrate from physical infrastructure to the cloud and the standard best practices to do so. Although these are important concepts for SMEs to understand, there aren’t nearly as many resources for those who are considering cloud-to-cloud (C2C) migration. If you’re already in the cloud but are looking to make a change due to cost, performance or another business-critical reason, this blog is for you.
C2C migration is a delicate process that requires a very detailed execution plan to ensure your mission-critical functions never skip a beat and your end users’ service remains uninterrupted. Below we highlight some of the top C2C migration best practices to keep in mind:
Cloud Provider Evaluation
The first, and likely most important factor to C2C, is determining who your new cloud provider will be. Beyond the standard questions about pricing and reliability, make sure you evaluate the following:
Flexibility: Cloud computing is not a one-size-fits-all proposition. You’ll want to ensure your new cloud provider has the flexibility and know-how to evaluate your specific business needs and craft a solution that is tailor-made to meet them.
Security: These days, there are few factors more important than security. IT personnel are focused on preventing and detecting cyberattacks at all costs. Be sure to ask your cloud provider about their security protocols and auditing processes. Ensuring security is a full-time job that calls for constant monitoring, adjustment and maintenance. You need a provider that takes security as seriously as you do.
Plan, Plan, Plan!
The pre-migration portion of your C2C migration plan is critical. You’ll need to work with your cloud service provider to determine the type of migration, overall timeline and the lowest traffic window for end-users in which to enact the migration. Below are options to consider in your plan:
New Cloud Environment: With this approach, the cloud provider creates an entirely new cloud environment for customer applications. Once the cloud environment is constructed to the customer’s liking, the old cloud environment is replaced in favor of the new environment. This option is particularly attractive to companies that are looking to make major changes to the way their cloud is configured.
Shutdown and Copy Virtual Machines (VMs): In this situation the cloud provider and customer strategically choose a period of time that has low traffic (such as a weekend or late night/early morning) to shut down the existing VMs, copy the cloud environment as is and reinstate the environment within the new provider’s VMs.
Flip and Switch: This option is similar to the above, but instead of copying VMs after they have been shut down, the cloud provider copies the live VMs to its environment for an instantaneous “flip and switch.”
Another crucial portion of the planning phase is determining your monitoring strategy. You’ll want a well thought out strategy in place, so that once the migration is complete the monitoring process can begin immediately.
