Azure Container Service vs rkt: What are the differences?
Developers describe Azure Container Service as "Deploy and manage containers using the tools you choose". Azure Container Service optimizes the configuration of popular open source tools and technologies specifically for Azure. You get an open solution that offers portability for both your containers and your application configuration. You select the size, the number of hosts, and choice of orchestrator tools, and Container Service handles everything else. On the other hand, rkt is detailed as "App Container runtime". Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.
Azure Container Service belongs to "Containers as a Service" category of the tech stack, while rkt can be primarily classified under "Virtual Machine Platforms & Containers".
Some of the features offered by Azure Container Service are:
- Create a container hosting solution optimized for Azure
- Scale and orchestrate applications using Apache Mesos or Docker Swarm
- Use popular open source, client-side tooling
On the other hand, rkt provides the following key features:
- Composable. All tools for downloading, installing, and running containers should be well integrated, but independent and composable.
- Security. Isolation should be pluggable, and the crypto primitives for strong trust, image auditing and application identity should exist from day one.
- Image distribution. Discovery of container images should be simple and facilitate a federated namespace, and distributed retrieval. This opens the possibility of alternative protocols, such as BitTorrent, and deployments to private environments without the requirement of a registry.
"Easy to setup, very agnostic" is the top reason why over 3 developers like Azure Container Service, while over 3 developers mention "Security" as the leading cause for choosing rkt.
rkt is an open source tool with 8.71K GitHub stars and 832 GitHub forks. Here's a link to rkt's open source repository on GitHub.
