Migrate to the Cloud with Confidence

At QBurst, we focus on identifying business and IT drivers, assessing the existing setup, and defining a cloud migration roadmap that will also accommodate future business needs. We follow an iterative approach to migration that ensures minimum disruption to your operations. First in our cloud migration service is the migration consulting and discovery phase.

Stages in Cloud Migration

Executing the Migration

During cloud migration, applications need to be ported and tested in a streamlined manner. We set up beta environments and fine-tune applications using test data. Once the new cloud environment is ready, production data is moved to the cloud.

Production switchover can be done either all at once or in phases. We can move the entire application to the cloud and verify it works there while consumers continue to access the on-premises database. With one-way synchronization to the cloud-based database, we just need to switch the traffic from on-premises stack to the cloud stack when it is ready.

A phased approach is when we move consumers of the data in batches with bi-directional syncing between on-premise and cloud databases. Cloud and on-premises environments operate in parallel, allowing data, applications, and users to move in phases without disrupting normal operations. Post migration of each phase, we test, verify, and move the next batch. Once all the customers are moved to the cloud-based application, we remove the on-premises version.

Post migration and verification, we start the monitor-optimize cycle. We move the application to its steady state where our managed services practice can run and maintain it. Our runbooks will make sure everyone has the information necessary to keep your apps running and supported through the rest of their lifecycle. Learnings from the initial migration are used to improve and tweak the migration plan of the next set of applications or services.
