Containers

• VMs do not make best use of space and Apps are not isolated which could cause config conflicts, security problems and resource hogging.
• Containers allow you to run multiple apps which are virtually isolated from each other.
• Monolithic Architecture is where one app which is responsible for everything and functionality is tightly coupled.
• Microservices Architecture is where multiple apps which are each responsible for one thing and function is isolate and stateless.
• Kubernetes is an open-source container orchestration system for automating deployment, scaling and management of containers.
• Kubernetes is called "K8".
• A unique component of Kubernetes is called a "Pod".
• Docker is a set of Platform as a Service (PaaS) products that use OS-Level virtualization to deliver software in packages called "containers".
• Open Container Initiative is an open governance structure for creating open industry standards around container formats and runtime.
