Cloud migration

What is software testing for cloud migration?

When migrating applications to the cloud, huge volumes of data must be moved from one system to another, introducing a great deal of risk into the process. Any small mistake during migration can cause data to be corrupted or go missing. Application components may be migrated to the wrong location, causing applications to break. After migration, software in the cloud may not be compatible with other applications, and integrations with third-party solutions may not function. As a result, servers may fail, systems may go down, and database errors may cause business disruption.

To ensure a smooth cloud migration, software testing is essential to ensure that the applications that have been moved to the cloud are in the right place and that they work as intended.

Essential tests for cloud migration

After a cloud migration, the following tests can help ensure a functional, stable, and secure environment.

• Functional testing determines the production-readiness of apps that have been migrated to the cloud. Testing verifies that key aspects of the migrated applications still perform as intended or that they meet performance levels specified in SLAs. Functional validation can show whether valid inputs generate expected results, whether object references and page layouts work as intended, and whether applications are compatible and integrate with other software, systems, and services.
• Integration testing evaluates whether third-party integrations are still intact and whether applications can communicate seamlessly with other services.
• Security testing is designed to eliminate the risks of running software systems in the cloud. Types of testing includes business process security testing, application transaction security testing, user privacy security testing, data privacy testing, and data security testing.
• Performance testing validates how well an application can scale in this cloud and how cloud migration has affected response time.
• Load testing ensures that migrated applications will continue to operate smoothly during spikes in traffic and at times when user volume is higher than anticipated.

Benefits of automated testing for cloud migration

Testing after a cloud migration offers several significant benefits.

• Ensure business continuity. Testing can help ensure that business-critical processes are not disrupted and that every word, number, and bit of data has been moved to the right location.
• Prevent data loss. Testing can help to validate the integrity of legacy databases.
• Protect productivity. Automated testing can help to find and fix mistakes that are the result of migration, ensuring data and content are migrated to the correct destination.
• Reduce costs. Automated testing allows testers to accomplish more with less time, minimizing the total cost of migration.
• Increase security. Testing can help to pinpoint missing security controls or identify compliance configurations that may have been lost, damaged, or destroyed during cloud migration.
