This ensures that the migration project stays on track, achieves its objectives, and delivers value to the business.

Step 2 – Choose a cloud migration strategy

Choosing the right cloud migration strategy is crucial for optimizing the benefits of moving to the cloud while minimizing risks and disruptions to business operations and making a clear cloud migration project plan. Here are some common cloud migration strategies to consider:

• Rehost (Lift and Shift): This strategy involves lifting existing applications and workloads from on-premises infrastructure and shifting them to the cloud without making any significant changes to the application architecture.
• Replatform (Lift, Tinker, and Shift): Replatforming involves making minor modifications to applications or infrastructure components to optimize them for cloud environments while preserving core functionality.
• Refactor (Re-architect): Refactoring involves redesigning and rearchitecting applications to leverage cloud-native technologies and services fully. This may include breaking monolithic applications into microservices, adopting serverless architectures, or integrating with cloud-native databases.
• Repurchase (Drop and Shop): Repurchasing involves replacing existing applications or software with cloud-based alternatives or Software-as-a-Service (SaaS) solutions.
• Retain (Keep as Is): This strategy involves maintaining certain applications or workloads on-premises while selectively migrating others to the cloud.

When choosing a cloud migration strategy roadmap, organizations should consider factors such as the complexity of their existing infrastructure, application dependencies, security requirements, performance objectives, and long-term business goals. It’s also essential to involve stakeholders from across the organization and seek expert cloud migration project plan from specialists to ensure the smooth and successful execution of cloud migration steps.

Step 3 – Define cloud migration success

Defining success for a cloud migration project involves setting clear objectives, benchmarks, and key performance indicators (KPIs) to measure the effectiveness and impact of the migration effort.

Key performance indicators (KPIs) for cloud migration help assess the effectiveness, efficiency, and impact of the migration project. Once these have been identified, you should also bring them into your project plan for cloud migration. Here are some common KPIs to consider:

Cost Savings/ROI: Measure the cost savings achieved through the migration compared to the previous on-premises or legacy infrastructure. This could include reduced infrastructure costs, operational expenses, or licensing fees. KPIs include:

• Total cost of ownership (TCO) reduction
• Return on investment (ROI) from the migration

Resource Utilization and Efficiency: Evaluate the utilization of cloud resources (e.g., compute, storage, networking) to ensure optimal allocation and cost-effectiveness. KPIs include:
