Understanding What is AWS Docker and Related Concepts

AWS Containers

Docker provides simple commands to help build, start and run the containers. It can be run and managed at scale using the various available services.

The services include :

1. ECS or Elastic Container Service
2. EB or Elastic Beanstalk

The degree of control regarding scheduling, capacity, and scaling of applications mark the distinction between these services. Now let’s discuss the benefits of using Elastic Container Service or ECS with AWS or Amazon Web Services Fargate.

Using Elastic Container Service or ECS With AWS

We are allowed to run AWS Docker containers without any EC2 instances, which is possible for AWS Fargate.

Without provisioning, clustering, or managing the cluster of virtual machines, the containers can be run by us as it acts as a sole compute engine for workloads.

Let us now look at the process of running Docker containers.

Running AWS Docker Containers

Running Docker containers includes:

• Building the container images.
• Defining the computer resources and the memory required.
• Running and managing applications.

By removing the need to run and manage the compute infrastructure, AWS Fargate allows it to focus on the application entirely.

Now let’s discuss how to use AWS EB or Elastic Beanstalk with the single container Docker.

Using AWS EB or Elastic Beanstalk With Single Container Docker

Elastic Beanstalk helps in deploying, managing, and scaling web services and applications. It also helps in many other processes like deploying, load balancing, patching, and scaling.

Docker containers in the Elastic Beanstalk can run in three specific ways, namely:

1. Using the Dockerrun.aws.json file.
2. Creating a docker file and then uploading it to Elastic Beanstalk.
3. Creating a zip file with docker file and uploading it to Elastic Beanstalk.

There is another feature where the applications can be started or stopped by us as a unit, through the console of Elastic Beanstalk.

Now let us discuss some important facts about using this docker.

Use of Docker

Docker technology provides multiple benefits to developers such as a robust ecosystem of tools and off-the-shelf applications that are ready to use with Docker to name a few. Other benefits include:

• Faster Shipping  

The software can be shipped seven times faster than the users who do not use Docker. Our containers can be run in different environments using Docker.

• Save Money

One of the best ways to run workloads in AWS is Amazon ECS with Spot Instances. We can utilize the unused compute capacity in AWS using spot instances and run containerized workloads at a fraction of the cost. Docker containers also  improve server utilization thus helping in cost saving.

• Standardize Operations

By using Docker, issues can be identified, rolled back and remediated effectively and the applications can be developed without having any errors in the code.

Conclusion

Applications can be quickly deployed and scaled into any environment using Docker. If the developers run Docker on AWS, then they and the admins are provided a highly reliable and low-cost way to build, ship, and run distributed applications at any time. This docker lets us build, test, and deploy our applications quickly. So using Docker with AWS is very efficient.
