In my experience, cloud-to-cloud migration has not been an easy task. I have attempted to do that twice and it was a hair-raising experience each time. I once had a big challenge with collocation when one of the cloud providers decided to close shop. They gave us a 60-day notice after which our datacenter would no longer be in operation. They had worked with us for four or five years and then they just decided as a group that they no longer want to be in that business. It was a serious problem trying to separate the servers from the cloud in their infrastructure to make sure we can migrate and collocate them into different premises. It created a serious amount of logistical issues, downtime and unhappy customers — it was not a good place to be in.

Unless you have 100% containerized your applications, it's not a migration — it's a rebuild.

That’s true. And I don't think anyone has reached 100% containerization, at least no one that I know of.

For enterprises, cloud-to-cloud migration is not possible. It's only possible for some small companies who were started recently, like startups. Enterprises will stay where they are, but they might move some background processes to a cheaper solution on the same platform. For instance, instead of using easy tools to run certain things, they might go for the containerized solution; then they can control it and don't have to pay the extra price.

In my experience, cloud-to-cloud migration is one of the most complicated tasks. Even with rising costs, I do not want to get myself involved in that. You get to a point where you have to look for your own support, which takes a lot of time. And the users, whether they are clients or colleagues, don’t have the patience to wait long enough for that transition to happen. I wouldn't encourage moving from cloud to cloud. If you are using Google, Azure, etc., you’d better stay there.

Would love to hear from anyone who has successfully taken a more proactive approach to cloud cost-savings versus a reactive approach? What strategies or tactics have been key in your success?

How much does Anthropoic (or another high profile company like it) announcing that their primary cloud provider will be AWS, impact your own views on cloud vendor selection? Does it change them or is it a non event?
