Heterogeneous deployment

The ability of Microservices to be executed as an isolated process decouples it from the constraints around a specific hosting environment. For instance, services can be deployed across multiple cloud stacks such as IaaS and PaaS and across different operating systems such as Windows and Linux hosted on private data centers or on cloud. This decouples the technology limitations from the business requirements.

Most of the mid and large sized companies are now going through a cloud transformation. These companies have already invested significant resources on their on-premises data centers. This forces cloud vendors to support hybrid computing models where the IT infrastructure can coexist across cloud and on-premises data centers. In this case, the infrastructure configuration available on-premises may not match the one provisioned on cloud. The magnitude of application tiers in a monolithic architecture may prevent it from being deployed on less capable server machines, making efficient resource utilization a challenge. Microservices, on the other hand, being smaller, decoupled deployment units, can easily be deployed on heterogeneous environments.
