Question

What are the common pitfalls in migrating DevOps services across cloud providers, and how can they be avoided?

Moving DevOps services to a new cloud provider introduces challenges like reconfiguring infrastructure, ensuring service compatibility, and managing downtime. This question focuses on identifying common pitfalls and strategies to mitigate risks, ensuring a seamless transition with minimal impact on operations.

Answer 1

Risks may arise while moving DevOps services between cloud providers. Typical problems and fixes consist of:

Configurations Particular to a Platform:

AWS Lambda and Azure Functions are examples of cloud-native services that might need to migrate better to other platforms.

Solution: Standardize setups using infrastructure-as-code technologies (Plumi, Terraform).

Data Loss and Downtime:

Service outages during migration are a potential hazard.

Solution: Use backup/restore procedures and schedule incremental migrations.

Incompatibilities between services:

Risk: Disparities in networking setups or APIs.

Solution: Prior to a complete migration, test services should be provided in the new environment.

Overspending on costs:

Risk: Unexpected expenses as a result of using both providers at the same time during the move.

Solution: Plan and use resources as efficiently as possible.

Configurations for security:

Risk: Inaccurately set up security groups or IAM roles in the new cloud.

Solution: During migration, audit and test security setups.
