Azure Container Service provides orchestration tools beyond just Docker. It supports Docker Swarm for container orchestration across multiple hosts using the Docker API. It also supports Kubernetes for grouping containers into pods for management across hosts. Additionally, it supports DC/OS which offers container orchestration and was built by Mesosphere offering container grouping, scheduling, and management. The document discusses the advantages of containers over VMs and various container orchestration tools available in Azure Container Service beyond just Docker.

- 2. Agenda Scaling and Orchestration Containers Advantages Containers vs VMs Introduction to Containers Demo 1 2 3 4 5 Questions6
- 3. Containers vs Virtual Machines Pack many more containers on a host machine than you can virtual machines Each VM is a self-contained system in its own right, with its own operating system and virtualized hardware and its own unique resources. …result is significantly faster deployment, much less overhead, easier migration, faster restart
- 4. Containers Advantages Secure Containers isolate applications from each other and the underlying infrastructure while providing an added layer of protection for the application. Open Docker containers are based on open standards allowing containers to run on all major Linux distributions and Microsoft OS with support for every infrastructure. Lightweight Containers running on a single machine all share the same operating system kernel so they start instantly and make more efficient use of RAM.
- 5. Orchestration Enables the definition of simple multi-container applications Docker Compose Manages and organizes Docker containers across multiple hosts via the same API used by a single Docker host Docker Swarm Orchestration and management solution that actually predates Docker, but has recently added support for Docker into its built-in application framework Marathon. Mesos – DC/OS Deis Open source PaaS platform to deploy and manage applications integrated with Docker Open-source solution built by Google offering container grouping into “Pods” for management across multiple hosts, also supported on Azure Kubernetes

- 11. Azure Container Service – DC/OS 1. Proven scalability 2. Fault-tolerant replicated master and slaves using Apache ZooKeeper 3. Support for Docker-formatted containers 4. Native isolation between tasks with Linux containers 5. Multiresource scheduling (memory, CPU, disk, and ports) 6. Java, Python, and C++ APIs for developing new parallel applications 7. A web UI for viewing cluster state
