Containers-as-a-Service (CaaS) is an emerging services offering for container-based virtualization in which providers offer a complete framework to customers for deploying and managing containers, applications and clusters.
The Containers-as-a-Service model is designed to help both developers and IT departments develop, run and manage containerized applications. In a CaaS model, containers and clusters are provided as a service that can be deployed in on-premises data centers or over the cloud.
CaaS offers flexibility and expandability that small and medium-sized business might not otherwise afford, allowing for the addition of devices, modes or coverage on demand. The network capacity and feature set can be changed from day to day if necessary so that functionality keeps pace with demand and resources are not wasted. There is no risk of the system becoming obsolete and requiring periodic major upgrades or replacement.
For developers, a CaaS model streamlines the process of building a scaled-out container and applications deployment. For IT departments, Containers-as-a-Service offers a completely enabled container deployment service with security and governance control for IT management.
