Aligning cloud migration efforts with your business goals is crucial for ensuring the success and sustainability of the migration. Cloud migration is more than an IT project. It's a strategic move that can significantly impact your business operations, efficiency, and bottom line. When cloud migration is in sync with your business objectives, it maximises return on investment (ROI), enhances agility, and supports long-term growth.
Conducting a comprehensive assessment of your current IT landscape is a critical step in preparing for cloud migration. This process involves evaluating all aspects of your IT infrastructure, applications, and data to determine their readiness for the cloud. A thorough assessment ensures that you identify potential challenges and make informed decisions about what to migrate, modernise, or retire.
Designing a detailed migration plan is essential for ensuring a smooth transition to the cloud. A well-structured plan should address timelines, resource allocation, and risk management, setting the foundation for a successful migration.
Selecting the appropriate cloud model—public, private, or hybrid—is crucial for meeting the specific needs of your enterprise. Each model offers distinct advantages and should be evaluated based on business requirements, regulatory constraints, and technical considerations.
For a deeper understanding of cloud models and their benefits, read the National Institute of Standards and Technology (NIST) definition of cloud computing.
Choosing the correct migration strategy is crucial to ensuring a successful cloud migration. Different strategies suit various business needs, application requirements, and organisational goals. Here is an overview of the most common migration strategies and how they can be applied:
Rehosting involves moving applications to the cloud without making significant changes to their architecture. This strategy is often referred to as "lift and shift." It allows organisations to quickly migrate to the cloud, as it involves minimal adjustments.
Benefits:
Applications:
Replatforming involves making slight modifications to applications to optimise them for the cloud environment. This might include using cloud-based services for databases or storage, which can improve performance and reduce costs.
Benefits:
Applications:
Refactoring involves re-architecting applications to fully leverage cloud-native features and services. This strategy often requires significant changes to the application code and architecture.
Benefits:
Applications:
Reprovisioning involves rebuilding applications from scratch in the cloud. This approach utilises modern architectures and technologies to maximise the benefits of the cloud.
Benefits:
Applications:
Repurchasing involves moving to a new cloud-native solution or SaaS product, replacing existing applications. This strategy is particularly useful when the current application does not justify the effort or cost of migration.
Benefits:
Applications:
Relocating involves moving physical workloads, such as virtual machines or storage, directly to a cloud provider without changes. This approach often involves physical or digital transfer of data and workloads.
Benefits:
Applications:
Cold migration refers to moving applications and data to the cloud during planned downtime. This approach is typically used for applications that can tolerate extended periods of downtime.
Benefits:
Applications:
Live migration involves moving applications and data to the cloud with minimal downtime. This strategy is essential for mission-critical applications that must remain operational during the migration process.
Benefits:
Applications:
The execution phase of cloud migration is where the detailed plans and strategies come to life. Ensuring a smooth transition to the cloud requires a well-coordinated effort and adherence to best practices. Following the migration, optimisation is essential to fully leverage the benefits of the cloud in terms of cost, performance, and security.
