The Basics

What are Containers?

00:05:26

Lesson Description:

Let's get started by talking about what containers are. This lesson covers the basics of what containers are and how they relate to virtual machines.

What are Containers Used For?

00:03:36

Lesson Description:

Now that you have a better understand of what containers and orchestration are, let's talk a little more about how containers can be used. This lesson will provide a clearer idea of the kinds of things containers can be used to accomplish. This will prepare you for more detailed discussion leater on about real-world use cases for containers and orchestration.

Advantages and Limitations of Containers

00:03:42

Lesson Description:

Now that we have talked about the basics of containers and orchestration, let's summarize some of the advantages of containers. In this lesson, we will also talk briefly about some the limitations and challenges associated with containers to give you a better understanding of what they can (and cannot) do. After completing this lesson, you will be ready to begin exploring some of the tools that can help you do containers and orchestration.

Container and Orchestration Technologies

What is Docker?

00:02:15

Lesson Description:

One of the tools that comes upmost often in discussions about containers is Docker. Docker offers a powerful implementation of container technology, and is currently the most popular container runtime. In this lesson, we will talk about what Docker is and its relationship to the concept of containers. After completing this lesson, you will have a basic knowledge of what Docker is and what it does. You can find more information about Docker at the offical Docker site: https://www.docker.com/

What About Other Container Runtimes?

00:03:44

Lesson Description:

Docker is not the only option for running containers. In this lesson, we will talk about some popular Docker alternatives, including rkt and containerd. After completing this lesson, you will have a general understand of the veriety of tools that is available in the container space, and you will be aware of some of Docker's main competitors. You can find more information on the container runtimes discussed in this lesson here:rkt - https://coreos.com/rkt/containerd - https://containerd.io/

What is Kubernetes?

00:01:45

Lesson Description:

The benefits of containers really shine when containers are paired with orchestration tool. Orchestration tools help you manage your containers, and they make it easy to implement the kinds of automation that can help you get the most out of containers. The industry leader in container orchestration tools is Kubernetes. In this lesson, we will talk about what what Kubernetes is and how it relates to containers. After completing this lesson, you will have a general idea of what Kubernetes is and how it can help you. Check out the official Kubernetes site for more info: https://kubernetes.io/

What About Other Orchestration Solutions?

00:04:06

Lesson Description:

There are plenty of orchestration tools besides plain Kubernetes that are available to help you manage your container infrastructure. In this lesson, we will talk about a few of these tools. We will also talk about some of the out-of-the-box orchestration functionality offered by cloud providers when you are running containers in the cloud. After completing this lesson, you will have a general knowledge of the wide range of container orchestration solutions that are available. Check out these links for more information on the orchestration solutions discussed in this lesson. Orchestration Tools: Docker Swarm: https://docs.docker.com/engine/swarm/Marathon: https://mesosphere.github.io/marathon/Nomad: https://www.nomadproject.io/ Cloud Orchestration Solutions: Amazon Elastic Container Service: https://aws.amazon.com/ecs/Amazon ECS for Kubernetes: https://aws.amazon.com/eks/Azure Kubernetes Service: https://azure.microsoft.com/en-us/services/kubernetes-service/Google Kubernetes Engine: https://cloud.google.com/kubernetes-engine/IBM Cloud Kubernetes Service: https://www.ibm.com/cloud/container-serviceRed Hat OpenShift: https://www.openshift.com/

Use Cases

Microservices

In this lesson, we will talk about what continuous deployment is and how containers can help you implement continuous deployment.

Self-Healing Applications

00:02:49

Lesson Description:

One way to provide applications with greater resiliency and reliability for customers is to implement self-healing functionality. Self-healing allows systems to detect and correct problems in real time, often before those problems are noticed by users. In this lesson, we will discuss what self-healing applications involve, as well as how containers and orchestration tools can help you more easily implement self-healing functionality.

Developer Visibility

00:03:38

Lesson Description:

One of the problems that has plagued IT organizations in the past is lack of developer visibility. When code does not work properly in a production environment, developers are unable to see how the code is truly behaving in production since they cannot access the system. This hinders the ability of the organization as a whole to quickly dignose and fix issues. In this lesson, we will discuss the problem of developer visibility and how containers can help overcome that problem by increasing developer visibility.

Containers in the Cloud

Doing Containers in the Cloud
