Microcontainers vs DevSpace Cloud: What are the differences?
What is Microcontainers? Tiny, Portable Docker Containers. A Microcontainer contains only the OS libraries and language dependencies required to run an application and the application itself. Nothing more. Rather than starting with everything but the kitchen sink, start with the bare minimum and add dependencies on an as needed basis.
What is DevSpace Cloud? Secure Multi-Tenancy and On-Demand Namespace Provisioning for Kubernetes. It lets IT teams create an internal Kubernetes offering that enables their developer teams to create isolated namespaces in shared development clusters. The goal is to allow engineers to get access to Kubernetes in a self-service fashion. It restricts developers to their own namespaces allowing secure cluster sharing while handling all the admistrative overhead such as the management of the kube-context on an engineers machine.
Microcontainers and DevSpace Cloud can be categorized as "Container" tools.
Some of the features offered by Microcontainers are:
- Size — MicroContainers are small. As shown above, without changing any code the image is 22 times smaller than a typical image.
- Fast/Easy Distribution — Because the size is so much smaller, it’s much quicker to download the image from a Docker registry (eg: Docker Hub) and therefore it can be distributed to different machines much quicker.
- Improved Security — Less code/less programs in the container means less attack surface. And, the base OS can be more secure (more below).
On the other hand, DevSpace Cloud provides the following key features:
- Strict Namespace Isolation and Secure Multi-Tenancy
- Admin UI for Managing Users & Permissions
- Optimized for Self-Service & Great Developer Experience
