Container technology derives its name from the shipping industry. As opposed to transporting goods as individual units with various packed sizes, goods are placed into steel containers, which are a standardized size, allowing for easier storage and more seamless transportation. The container can be moved as a unit, which saves time and money.<\/span><\/p>\n

In the tech world, containerization is a method used to package an application allowing the software, and its dependencies (including libraries, binaries and configuration files) to run together, isolated from other processes. By packaging them into a container, they can migrate as a unit, avoiding the differences between machines such as underlying hardware or OS differences, which can cause incompatibilities and critical errors. Containers also help enable smoother deployment of software to a server or network of servers.<\/span><\/p>\n

Container technology gathered momentum in the 2000s with the introduction of Free BSD Jails. However, it wasn\u2019t until the introduction of the container management systems Docker Swarm and Apache Mesos that containerization really began to take hold within the wider industry. When Kubernetes was released in 2017, it quickly became the de-facto standard for container management systems because it made container orchestration significantly easier to manage and more efficient.<\/span><\/p>\n

Containers as a Service (CaaS)<\/b><\/h3>\n

In 2020, a <\/span>survey conducted by the Cloud Native Computing Foundation (CNCF)<\/span><\/a> found that 84% of respondents were running containers in production. With containers now widely considered a standard unit of deployment, many organizations have adopted Containers as a Service (CaaS) solutions to streamline their container orchestration (i.e. Kubernetes) operations.<\/span><\/p>\n

What is CaaS? It is a service model that enables users to manage and scale containers, applications and clusters. It does this through a container-based virtualization, API, or a web portal interface. While there are different types of implementations available, all CaaS offerings essentially do the same thing. That is, they help organizations manage their containerized applications in a safe, scalable manner, whether on the cloud, on-prem or (as we\u2019ll go into more) at the Edge.<\/span><\/p>\n
