Dynamic Tenant Provisioning and Service Orchestration in Hybrid Cloud

The advent of container orchestration and cloud computing, as well as associated security and compliance complexities, make it challenging for the enterprises to develop robust, secure, manageable and extendable architectures which would be applicable to the public and private cloud. The main challenges stem from the fact that on-premises, private cloud and third-party, public cloud services often have seemingly different and sometimes conflicting requirements to tenant provisioning, service deployment, security and compliance and that can lead to rather different architectures which still have a lot of commonalities but evolve independently. Understanding and bridging the functionality gaps between such architectures is highly desirable in terms of common approaches, API/SPI as well as maintainability and extendibility. The authors discuss and propose common architectural approaches to the dynamic tenant provisioning and service orchestration in public, private and hybrid clouds focusing on deployment, security, compliance, scalability and extendibility of stateful Kubernetes runtimes.
