![]() ![]() A Docker Cluster is made up of different instances called Nodes. This helps with your application’s load balancing and also improves its availability. Swarm ArchitectureĪs you study for your exam, you should develop a high level of familiarity with the structure and architecture of Docker Swarm.ĭocker Swarm lets you integrate different Docker machines onto a single cluster. Let’s explore some of these areas in detail. Service in Swarm- placements, global, parallelism, and replicated.Rolling Updates, Rollbacks, and Scaling.Swarm High Availability and the Importance of Quorum.With Docker Swarm, you can always monitor the state, health, and performance of your containers and the hosts that run your applications.Īs you prepare for the DCA exam, some of the topics of Docker Swarm that you’ll need an in-depth understanding of include: Docker Swarmĭocker Swarm helps you run applications on the Docker Engine seamlessly through multiple nodes that reside in the same containers. Kubernetes is a popular container orchestration solution that offers plenty of customization options and unmatched auto-scaling capabilities.įor this part of the study guide series, we shall cover Docker Swarm.MESOS is challenging to use, and is only recommended for advanced Cloud developers.Docker Swarm is hugely popular and easy to set up, yet has a few drawbacks when it comes to autoscaling and customizations.Three of the most popular Container Orchestration tools are Docker Swarm, Kubernetes, and MESOS. With container orchestration tools, you can also provide advanced networking between various containers. Container orchestration tools also help scale your application’s instances up or down in response to fluctuations in demand. Container orchestration will help you set up a large number of application instances using a single command. Container Orchestration requires a set of tools and scripts that you can use to host, configure, and manage containers in a production environment.ĭeploying in Docker typically involves running various applications on different hosts. An essential part of preparing for the Docker Certified Associate (DCA) exam is to familiarize yourself with Container Orchestration. ![]()
