What is a cloud migration?
Cloud migration involves transferring your digital assets, such as data, applications and IT resources, from on-premises infrastructure to a cloud-based environment. This transformation gives you the advantage of cloud computing’s scalability, flexibility and cost-efficiency.
In many enterprise environments, cloud migration is performed incrementally and may result in hybrid architectures rather than a full cloud-only footprint. Depending on your needs, cloud migration can include shifting data to a single cloud provider, multiple cloud providers or a hybrid cloud environment.

Types of cloud migration
Understanding the different types of cloud migration strategies will help you successfully execute your project. You can use various methodologies that offer unique benefits and challenges.
Rehosting (lift and shift)
Rehosting, commonly called “lift and shift,” means moving applications directly to the cloud without altering their architecture. This straightforward method minimizes disruption, making it perfect for a quick move to the cloud.
While rehosting enables rapid migration, it may not deliver cost or performance benefits without post-migration optimization.
Replatforming
Replatforming is when you make optimizations during the migration to take better advantage of cloud capabilities without changing the core architecture. This can include updating databases or modifying middleware, balancing the need for speed with cloud efficiencies.
Refactoring/re-architecting
Refactoring or re-architecting involves redesigning applications to be cloud-native, leveraging features like microservices and serverless computing. Though more complex and time-consuming, this provides substantial benefits in performance, scalability, and cost savings.
Retiring
During the migration process, some applications may become redundant. Retiring these applications means decommissioning them, simplifying your environment and reducing costs.
Retaining
Certain applications might need to stay on-premises due to regulatory, compliance or operational reasons. Retaining these applications enables them to continue to operate effectively while the rest of your IT environment transitions to the cloud.
Overview of cloud migration strategies
Executing an efficient and cost-effective migration to the cloud requires a well-thought-out strategy that minimizes risk. To facilitate a successful transition consider these five key strategies:
- Evaluate assets: Assess infrastructure, applications, data, and interdependencies for cloud suitability, including network, identity, and integration dependencies.
- Define objectives: Establish migration goals like cost reduction or improved performance. Use these to guide the process and align stakeholders.
- Choose a cloud model: Select from public (scalable, cost-effective), private (controlled, secure), or hybrid (combined benefits) based on your needs.
- Develop a roadmap: Create a detailed plan outlining migration phases, timelines, resources, and milestones to smooth out your execution.
- Execute and monitor: Follow the roadmap, adjusting as needed. Continuously monitor your progress to quickly identify and resolve issues so the migration stays on track.
Benefits of cloud migration
Migrating to the cloud offers numerous advantages that can significantly enhance your operations and competitive edge.
- Cost efficiency: Reduce or eliminate the need for on-premises hardware for significant savings on maintenance and operational costs. The pay-as-you-go pricing model allows you to only pay for the resources you use, optimizing cost management.
- Scalability: Scale resources up or down based on demand, a valuable option for businesses with fluctuating workloads or seasonal peaks. Quickly adding or removing resources allows applications to handle varying levels of demand without compromising performance.
- Flexibility and accessibility: Cloud-based applications and data can be accessed from anywhere, facilitating remote work and collaboration. Employees can work from different locations while accessing the same tools and information, boosting productivity and efficiency.
- Enhanced security: While cloud providers invest heavily in security controls and compliance certifications, customers remain responsible for secure configuration, identity management, and data protection under the shared responsibility model.
- Innovation: Freeing up IT resources from managing on-premises infrastructure lets you focus on strategic initiatives and innovative projects. The cloud provides access to technologies like artificial intelligence, machine learning and big data analytics to drive growth and stay competitive.

Steps to ensure long-term success post-migration
Following a well-thought-out framework and using the best cloud migration tools and strategies will give you a successful and sustainable cloud migration, unlocking the full potential of cloud computing.
Step 1: Proactive planning
Start with proactive planning. Regularly review your cloud usage and resource allocation to find areas for cost savings and performance improvements. Use tools from cloud vendors to monitor usage patterns and recommend optimizations for better efficiency.
