Pilvilähestymistavat

Pilvilähestymistavat refer to the various strategies and models organizations employ to migrate their applications, data, and IT infrastructure to cloud computing environments. These approaches are designed to manage the complexity and risks associated with cloud adoption, ensuring a smooth transition that aligns with business objectives.

A common approach is the "lift and shift" method, also known as rehosting. This involves moving existing applications to the cloud with minimal or no changes to their underlying architecture. It is often the fastest way to get to the cloud but may not fully leverage its benefits.

Another strategy is re-platforming, where applications are modified to take advantage of cloud-native services, such as managed databases or serverless computing, without changing their core architecture. This offers a balance between speed and optimization.

Re-architecting, or refactoring, involves fundamentally redesigning applications to be cloud-native, often breaking them down into microservices. This approach maximizes the benefits of the cloud, such as scalability, resilience, and agility, but requires significant time and resources.

The "replace" strategy involves discarding existing applications and adopting new, cloud-based solutions, such as Software-as-a-Service (SaaS) offerings. This can be effective for commoditized functions where off-the-shelf solutions meet business needs.

Finally, some organizations may choose to retire applications that are no longer needed or retain them on-premises if cloud migration is not feasible or cost-effective. The choice of pilvilähestymistapa depends on factors like application complexity, business requirements, budget, and technical expertise. Organizations often use a combination of these approaches to manage their diverse application portfolios.
