This method provides peace of mind and reduces potential disruptions.
  • Reduced Learning Curve: Organizations can leverage their existing knowledge and skills in managing and maintaining applications. Since the applications are moved to the cloud without drastic changes, the learning curve for cloud-native technologies and frameworks is minimized. This reduces the training and re-skilling efforts required for IT teams, enabling faster adoption of the cloud environment.

When to choose

Let's take a look at the important factors to consider when making a decision to move:

Time constraints: It is particularly suitable when there are time constraints and a need to move to the cloud quickly. Organizations can quickly move them to the cloud without disrupting project timelines or losing critical business opportunities by avoiding drastic application modifications or redesigns. This way allows companies to reduce time to market and gain a competitive advantage.

Budget constraints: By leveraging existing investments and minimizing redevelopment efforts, companies can reduce migration costs and allocate resources more efficiently. This solution ensures a smoother transition to the cloud without profound upfront investment in application redesign or re-engineering.

Application suitability: This approach works well for less complex applications with a low dependency on the underlying infrastructure. Applications with loosely coupled components, a minimum number of integration points, and limited interdependencies can be easily migrated to the cloud. This is especially suitable for standalone applications or those built on modern modular architectures.

Legacy applications: This is an ideal choice for migrating legacy applications that are difficult to refactor or redesign due to their complexity or lack of available resources. These applications may have large code bases, legacy dependencies, or outdated technologies that make a comprehensive re-architecture impractical. By migrating such applications unchanged, organizations can capitalize on the scalability and operational efficiency of the cloud without disrupting critical business processes.

Temporary workloads or test environments: This migration can be useful for transient workloads or test environments. Organizations may need to set up rapid development, testing, or experimentation environments quickly. By moving these workloads to the cloud, companies can avoid long-term infrastructure investments and reap the rewards of cloud resiliency of the cloud to scale up or down resources as needed.

Adherence to legal and compliance standards: For industries such as healthcare or finance, which are bound by rigid data privacy and security regulations, it may be necessary for organizations to transfer their applications to the cloud while keeping their current security protocols and compliance measures intact. By doing so, they can ensure that they remain compliant with regulatory and compliance demands.

Risks of lift-and-shift migration

While lift-and-shift migration has a range of merits, it's essential to consider the potential risks associated with this approach. Here is an outline of major aspects to keep in mind when choosing this option:

  • Suboptimal Performance and Scalability: Lift-and-shift migration may not fully leverage the scalability and performance capabilities of the cloud. Since the applications are migrated without profound changes, they may not be optimized for cloud-native features such as auto-scaling or distributed architectures. This can result in suboptimal performance and scalability, limiting the ability to fully harness the benefits of the cloud environment.
  • Inefficient Resource Utilization: Since the applications are migrated without reevaluating their resource requirements, they may continue to consume resources at the same level as in the on-premises environment. This can lead to overprovisioning or underutilizing cloud resources, impacting economic performance.
  • Limited Pros of Cloud Computing: Lift-and-shift migration only partially exploits the capabilities offered by the cloud, such as microservices architecture, containerization, or serverless computing. This can limit opportunities for innovation, flexibility, and agility that come with embracing cloud-native technologies.
  • Security and Compliance Challenges: While such a migration can maintain existing security controls and compliance measures, it may not fully leverage the cloud's enhanced security features. Organizations must carefully assess and address security and compliance requirements in the new cloud environment to ensure data protection.
