Despite what many cloud service providers (CSPs) advertise, moving to a public cloud isn’t quite as simple as swiping your credit card and clicking on a few buttons. While every customer’s situation will be different, the actual data migration can be time-consuming, labor-intensive, and disruptive. With the right preparation, however, it doesn’t have to be.
The following information can help you build your cloud migration plan — and ensure the success of the migration.
If you’ve done a cloud migration before and have sufficient resources for carrying one out, you’re ready to move ahead. Check back on your “lessons learned” from the previous migration and get your plan and resources in place.
If you’re a first-timer and/or are short on resources or are facing a complex move, don’t hesitate to enlist the help of a cloud services provider (CSP) or a cloud consultant. Many CSPs offer professional services specifically for handling cloud migrations.
Do your due diligence before committing to a CSP or other partner. Check references. Make sure any company you choose to work with can deliver what you need.
Whether you’re handling the move to the cloud internally or going with a partner, clear, concise, and frequent communication will be key. Make sure all participants in the migration understand their roles and responsibilities, the schedule, and the plan.
Make sure your applications are appropriate to move and ready to move. Assess them by asking these and any other pertinent questions:
For this last question, there are two important factors to consider: recovery time objective (RTO) and recovery point objective (RPO). RTO is the amount of time that it takes your business to recover from failure with acceptable losses. RPO is how long your business can operate without its data, respectively. The RTO and RPO for mission-critical applications will likely need to be close to or at zero.
You’ll also need to prioritize which applications move first. Their criticality and usage patterns will play key roles in this. It’s typically recommended that you start with non-critical applications to test both the migration method you use and the new infrastructure.
Common migration methods include:
When choosing a migration method, you’ll need to consider numerous variables such as:
Distance: How far are you from your designated cloud infrastructure?
Transport: Will you be migrating data over the Internet or Ethernet, or physically transporting it?
Cost: Will the migration process require you to pay for a courier service, Internet bandwidth, software, experienced labor or possibly conversion or migration tools? Have you built-in contingencies into your budget to cover unexpected issues that may arise? Risks: Will the number of servers increase the complexity of the job? Do you have enough bandwidth? Do you have a long enough window for completing the task? How will you protect your data while it is in transit? Will latency be an issue? Do you have the internal IT resources?
Size: How large is your server infrastructure? What migration methodologies are most appropriate based on the size of your workloads?
While there are numerous other components that go into a cloud migration plan, the information discussed in this blog will give you a good start. You’ll find more helpful tips in our blog Cloud Migration: Basic Considerations and our free eBook: Ready. Set. Migrate.
