The challenge of Cloud-to-Cloud Migration

There are many reasons to change the cloud provider or the cloud model. But migration is not an easy task. There are different migration options based on the underlying data.

  • For different reasons, it may be necessary to change the cloud model or provider.
  • There are different migration methods depending on the nature of the application being migrated.
  • The use of open source products such as Docker and Kubernetes allows faster migration and vendor independence.

Mastering the Migration

Before a company decides on a suitable cloud for its data and applications, it should be clear what the implications of the choice are. How can the use of open source in a company avoid vendor lock-in in the cloud? Which locations can the cloud provider offer? Is the preferred location included? Does the cloud provider offer all the technologies that are important? How big and reliable is the provider? And what happens if the provider no longer operates the cloud? Will the company be able to access its data without much effort?
When it comes to selecting a public or private cloud, it is usually the case that a public cloud offers more flexibility in terms of greater scalability, more functions and a larger selection of peripheral systems. Going private cloud is interesting for industries with high security requirements where environments need to be physically separated. But a private cloud can also be the cheaper alternative to the public cloud in the long term, especially if the required resources are more or less precisely determined in advance and no major performance peaks are to be expected as with the Christmas business.

For this reason, many large companies today use a multi-cloud strategy: depending on requirements, budget and long-term perspective, a public and/or private cloud is used.

The motives for choosing a cloud provider are different. Many users can access AWS, Google Cloud or Microsoft Azure via inexpensive offers or test accesses. Others choose an alternative or regional provider because they value a nearby location and personal contact. Whatever the original decision, whether it was price, reliability, ease of access, security requirements or compatibility, the starting point may have changed in the meantime. Perhaps the architecture of the application or business requirements has changed in such a way that a change of vendor is necessary. Or the cloud provider’s decision requires it to look for alternatives.
