  1. Migration: The migration phase is where your plans are put into action. Data and applications are moved from the on-premises infrastructure to the cloud. Minimizing disruptions to your operations during this phase is crucial, which requires diligent monitoring and management. You can adopt different migration strategies, such as rehosting (lift-and-shift), replatforming, repurchasing, refactoring, retiring, or retaining, each with its own benefits and challenges.
  1. Post-migration: Once the migration is completed, the work doesn’t stop. It’s essential to validate the success of the migration and ensure everything is working as expected. This phase falls under regular monitoring, performance optimization, cost management, and ensuring security and compliance.

Each phase of the cloud migration process presents its unique challenges and requires different skills and expertise. That’s where cloud computing courses come into play. A well-rounded program will cover all aspects of the migration process, providing you with the knowledge and tools to tackle any hurdles you may encounter during your cloud migration journey.

Strategies for Successful Cloud Migration

Just as there’s no one-size-fits-all solution in business, cloud migration also requires a tailored approach. Your chosen strategy largely depends on your business needs, resources, and objectives.

Here, we’ll explore some common cloud migration strategies and provide tips on how to choose the one that best suits your organization:

  1. Rehosting (Lift-and-Shift): This strategy involves moving applications and data from your existing environment to the cloud without making changes. It’s often the quickest and least expensive strategy, but it may not fully leverage the cloud’s capabilities.
  1. Replatforming: Replatforming means making a few cloud-optimized adjustments to your applications during the migration process, offering a good balance between cost, speed, and leveraging cloud benefits.
  1. Refactoring (Re-Architecting): Refactoring involves re-architecting your applications to take full advantage of the cloud’s capabilities. It’s the most time-consuming and costly strategy, but it can yield significant long-term benefits, especially for businesses looking to boost agility and speed.
  1. Repurchasing: This strategy involves moving from a traditional license to a cloud-based model. For instance, transitioning from a conventional customer relationship management (CRM) system to a cloud-based one like Salesforce.
  1. Retiring: After an assessment, you might find some of your applications are no longer needed. In such cases, you can eliminate them to save costs.
  1. Retaining: Some applications may need more time to be ready or suitable for cloud migration. It’s okay to retain these applications in your current environment until later.
