Abstract: 

Docker's Containers by packaging applications into portable, hardware-isolated containers are breathing fresh life into a lightweight and portable approach to virtualization architecture. A container-based approach, in which applications can run in isolation, without relying on a separate operating system per application, could save huge amounts of hardware resources. In effect, containers will act as the new generation of OS Hypervisor. containers will open the door to an additional level of virtualization to maximize consolidation. They even have the potential to provide a transformative catalyst to adoption of open-source software in Software Defined Data Centers [SDDC]. One of Docker's appeal has been in helping developers quickly get their applications from concept to production. This architecture is starting to see an explosive growth with adoption being promised by several leading virtualization vendors and Cloud Service Providers.But there are a few barriers and technical limitations to overcome for containers - such as container's inability to provide a virtual instance of windows on a Linux server - before they have an expanded universal adoption.

Learning Objectives

What are containers? How do they function? Where do they fit in the SDDC Stack?
What are their pros and cons versus existing data center virtualization architectures? What impact will they have on the existing VM based architecture in the SDDC stack
