How can enterprises successfully complete cloud migration?

Cloud migration , Mainly data migration , It involves moving data from one system to another . Server migration means moving data between two servers . therefore , Cloud migration usually requires moving data between two clouds or between your local server and the cloud . Although small migrations are relatively simple , However, large-scale migration requires thorough preparation and precise configuration of the target server , Whether they are local or in the cloud .

Cloud migration has many benefits , From reducing costs to improving performance and scalability , To diversified backup solutions . But all of this depends on the correct execution of your migration . below , We have collected 10 Two ways of practice , They can help you migrate servers to the cloud as seamlessly as possible .

1. Plan your migration strategy

The first thing for successful cloud migration is to clarify its reasons and business motives . You don't have to move all your infrastructure at once . It may be a good idea to start a phased migration with unimportant workloads , Especially if you don't have much experience in mobile servers .

2. Analyze your infrastructure

Before starting to migrate files , It is important to examine all elements of the infrastructure . Mapping all dependencies between various parts of the application will reduce the possibility of destroying something during the migration . Ask yourself which systems are easy to migrate to the new environment . also , Consider how each step in the migration will affect the entire enterprise architecture .

3. Improve your data

If your cloud migration is not in a hurry , Another practice is to plan enough time to review the data you plan to migrate . Think about all the redundancy in your database instance 、 Outdated or trivial (ROT) The content of . Why spend time and resources moving it ? Designing a way to clean up data will help you reorganize content 、 Improve security and delete sensitive information . for example , Old installed software updates 、 Backup and log files are usually areas where data is cleaned up before moving . Just make sure you keep them on a separate server at least 60 God , For a rainy day .

4. Cross business and IT Coordinate stakeholders

Due to business and IT The team didn't communicate their goals with each other in the whole process , Therefore, there will be many post migration problems . Make sure your practice checklist includes gathering a clear understanding of business objectives and technical challenges before starting cloud migration , To avoid delays and incomplete data transmission . Involve other stakeholders , They can help determine which applications should be moved first , Which applications are less relevant . Make sure they know of any interruptions in the migration process , If this will affect their work .

5. Isolate migration from normal operations

The first priority in any migration process is to ensure that no daily operations are interrupted . Use staging servers and configure them as close to production as possible , So that when everything is ready, the data can be migrated with small interruption .

6. Check all application stack requirements

Migrating the actual code base is only part of the problem . In order to successfully migrate to the cloud , Another practical way is to consider the current running environment and the situation on the target server .

7. Optimize accuracy , Then there's speed

Most companies migrate their servers to make everything work faster . But the important thing in the migration process is that everything continues to work as it should . Being fast and incorrect will make you accomplish nothing . therefore , If you are doing any code optimization , Make sure it runs on the new system first . You can optimize the speed at any time in the future .

8. Don't migrate applications in active development

Move applications that are not running or have errors between servers ( Or part of the application ) It can be very difficult , Because it is difficult to find the errors introduced in the migration process . The general idea of code synchronization is to first freeze and migrate the basis of the code base . Then test it , Then migrate only any code changes .

9. Test everything

Just like the overall plan of cloud migration itself , Your practice checklist should include a detailed plan for testing all systems in the new environment . After completing all tests , It can be considered that your migration has been completed , You can start optimizing the code or continue any previous development .

10. Backup and recovery strategies

Develop backup and recovery strategies , This includes all necessary steps to remove any and all migration steps . This includes keeping your previous infrastructure online and running for at least a week after the migration .
