What Does Containers as a Service Mean?
Containers as a service (CaaS) is a cloud service model that allows users to manage and deploy containers, applications and clusters through container-based virtualization. CaaS is highly useful to IT departments and developers in building secure and scalable containerized applications. With CaaS, this can be achieved using on-premises data centers or over the cloud.
Techopedia Explains Containers as a Service
Simply speaking, CaaS provides an easy way to set up a container cluster. Orchestration, which essentially automates key IT functions, is an essential quality of CaaS technology. Google Kubernetes, Docker Swarm, Rackspace Carina and Apache Mesos are all examples of CaaS orchestration platforms. Some public cloud CaaS providers include Google, Amazon Web Services (AWS), Rackspace and IBM.
CaaS is often considered to be a subset of IaaS (infrastructure as a service), but includes containers as its fundamental resource, as opposed to bare metal systems and virtual machines.
