In this blog article, we will go into the notion of Lift and Shift, investigate its process, describe the benefits it provides, assess its limitations, and finally reveal the promise it holds for enterprises venturing into the cloud.
What is Lift and Shift?
Lift and Shift, commonly known as “Rehosting,” is a cloud migration method that involves migrating existing applications and infrastructure from on-premises to the cloud without requiring significant adjustments or architectural changes. It effectively lifts the old system and moves it to a cloud infrastructure. This method enables enterprises to shift to the cloud swiftly while minimizing disturbance to their operations.
Lift and Shift Process
Lift and Shift cloud migration provides a streamlined way for enterprises to migrate their apps and infrastructure from on-premises to the cloud. In this section, we will explore the step-by-step process involved in Lift and Shift migration, ensuring a smooth and efficient transition.
Step 1: Application Assessment
The first critical stage in the Lift and Shift cloud migration process is to undertake a thorough application assessment. This evaluation entails determining which applications and workloads are acceptable for migration, taking into account aspects such as dependencies, compatibility with the target cloud environment, and any necessary adjustments or upgrades.
Step 2: Cloud Environment Setup
Once the applications to be migrated have been identified, the target cloud environment must be configured. This includes deciding on the best cloud platform (such as Amazon Web Services, Microsoft Azure, or Google Cloud Platform) and setting up the necessary infrastructure, such as virtual machines, storage, and networking.
Step 3: Data Migration
The migration of data is a vital component of the Lift and Shift process. It entails moving application-related data from the on-premises environment to the cloud infrastructure. Databases, files, configurations, and other pertinent data may be included. To ensure the integrity and completeness of the data during the migration, efficient and secure data transfer technologies such as data replication or bulk data upload should be used.
Step 4: Application Migration
This step involves the actual migration of applications. It entails cloning the application stack into the cloud environment, which includes the operating system, middleware, and application code. Application migration can be accomplished through a variety of means, including the creation of virtual machine images, containerization, and the use of migration tools offered by the cloud platform.
Step 5: Testing and Validation
To achieve a successful Lift and Shift migration, thorough testing and validation are required. Businesses should test the migrated apps thoroughly in this step to detect and correct any compatibility issues, performance bottlenecks, or configuration errors. To imitate real-world cases, test environments should be set up to closely mirror the production environment.
Step 6: Cut-Over and Go-Live
After the testing and validation phases are completed, the cut-over and go-live phases can begin. This entails moving real traffic and users from the on-premises infrastructure to the cloud environment. It is critical to have a well-defined plan for the cutover process, including rollback processes in the event of any unexpected issues.
Transitioning to the cloud through the Lift and Shift approach requires careful planning, meticulous execution, and continuous monitoring. Throughout the entire process, businesses should prioritize data security, scalability, and performance optimization.
