7 Tips for a Smooth Migration to the Cloud
The recent hurricanes, flooding and power failures in Texas, Louisiana, Florida, and Puerto Rico, the wildfires in California, and the earthquake in Mexico remind us that natural disasters are indiscriminate and can strike at any time. Even the best-laid plans for disaster recovery and contingency operations can be overwhelmed by the catastrophic scale of these events.
Nature has served up an effective sales pitch for moving to the Cloud.
Beyond water, wind and fire, there are other compelling reasons to move to the Cloud:
- Elasticity to flex in response to changing needs
- Pay-as-you-go pricing, frequently at a discount
- Accelerated time-to-readiness of the Cloud platform
- Exit from the tech refresh treadmill
- Reduced need for power consumption and cooling at a data center
Migration to the Cloud from on-premise servers or data centers requires careful consideration to minimize disruption and downtime. Migration of data and applications is inherently risky. Here are seven tips to a smooth migration:
- Do your research and plan thoroughly, including information security aspects, and backup and recovery methods.
- Perform a rigorous discovery of which legacy servers, applications, or services might not make a clean transition to the Cloud. This is also be a good time to evaluate whether to eliminate the technical debt in legacy systems. Old, monolithic applications aren’t getting any easier to support. Examine whether to switch to a modernized, microservices-oriented architecture that is loosely coupled and easier to manage and scale.
- Identify a good test case — low-hanging fruit to test assumptions and work through potential roadblocks. Start with the easiest server or the one with the fewest dependencies. Development and test servers are prime candidates.
- Execute a phased approach and build on your achievements. There is no need to migrate all data, servers or services at once. Tackle the more complicated cases after gaining experience.
- Adopt DevOps practices and serverless computing to take full advantage of the virtual platform and automation. Experiment with new technologies that would not be feasible to prototype in a data center.
- Study lessons learned to refine the process.
- Don’t do it alone! Many Cloud service providers can help, providing everything from white papers and demos to full professional services.
Don’t wait for a natural calamity to safeguard your operations. A move to the cloud now can protect your assets and avoid mishaps caused by unintentional oversights and human error, as well as the unpredictability of nature.
Microservices: the development of an application based on breaking a system into small, granular, modular, and independent services and then assembling them into a larger suite
Serverless: a set of functions already ingrained in Cloud services that are useful for quickly parsing events and data streams.
