Azure Container Service vs OpenStack: 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, OpenStack is detailed as "Open source software for building private and public clouds". OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.
Azure Container Service belongs to "Containers as a Service" category of the tech stack, while OpenStack can be primarily classified under "Open Source Cloud".
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, OpenStack provides the following key features:
- Compute
- Storage
- Networking
"Easy to setup, very agnostic" is the primary reason why developers consider Azure Container Service over the competitors, whereas "Private cloud" was stated as the key factor in picking OpenStack.
PayPal, HubSpot, and Wikipedia are some of the popular companies that use OpenStack, whereas Azure Container Service is used by QwikSense, Veris, and Sensewaves. OpenStack has a broader approval, being mentioned in 67 company stacks & 50 developers stacks; compared to Azure Container Service, which is listed in 8 company stacks and 7 developer stacks.
