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.

Cloud Migration Consulting and Strategy

As your cloud migration service provider, we help you answer pertinent questions and effect a successful transition to the cloud. Our cloud consultants will work with you to identify:

  • What to migratePrioritize the applications, processes, and infrastructure to be migrated.
  • How to migrateFormulate a migration strategy that aligns with needs and addresses potential risks.
  • Where to migrateChoose a reliable platform—private, public, or hybrid—as appropriate for the business.

Make periodic enhancements to take advantage of new functionalities introduced by the cloud provider.

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.

Cloud Readiness Assessment

Cloud Readiness Assessment

  • Prepare an inventory of the existing infrastructure
  • Assess the dependencies and risks involved
  • Identify the most suited cloud service provider
  • Suggest suitable cloud tools to replace/improve the existing environment
  • Plan and prepare final architecture diagram with DR and fault-tolerance options
  • Estimate the time and cost involved
Beta Environment Setup

Beta Environment Setup

  • Set up a beta environment of the existing environment
  • Test/fine tune application using test data and test database
  • Test scalability after loading production equivalent test data
Migration Strategy

Migration Strategy

  • Plan phased migration of the application and database
  • Estimate the required migration time and notify downtime if necessary
Migration

Migration

  • Build a new automated/non-automated production environment
  • Move production data and set up storage, DR, and fault tolerance
  • Update DNS records and other configurations
Continuous Monitoring

Continuous Monitoring

  • Set up monitoring tools
  • Keep watching logs, performance, response time, and load
