The ins and outs of cloud portability
Summary
The true lock-in points are the services, such as database, abstraction and automation, queuing, and monitoring, and templates that make your workloads more meaningful.Portability from one provider to another is a common demand of early cloud adopters and is very achievable with current tooling and template conversions.Each cloud provider uses its own format and tooling to create application and infrastructure templates, many of which have different versions for their own public and private offerings.For average use, an enterprise can pay for persistent usage in its own VM environment, and it can use public cloud resources for additional capacity in its time of need.The first tools are only now emerging, and the use cases are limited, especially because costs for public clouds simply don’t vary enough to drive significant brokerage demand.
