Containers are all the rage in the DevOps world, and for a good reason. They offer an efficient way to package code and dependencies for deployment. But once your containers are up and running, you need a way to manage and orchestrate them. This blog post will explore what AWS services you can use to manage and orchestrate your containers. By the end of this post, you should understand how various services support containers in AWS and how you can benefit from this. So let’s get started!

What are containers?
Containers are a type of virtualization that allows you to isolate an application or process from the underlying operating system. This isolation provides several benefits, including improved security, portability, and application performance. Containers are typically used to run web applications or microservices.
Docker is the most popular container platform, and it enables you to package an application or process with all of its dependencies into a single “container.” This makes it easy to deploy and run your application on any compatible host, regardless of the underlying operating system. Containers can also be used for serverless applications, which are event-driven and only run when needed.
Why use containers on AWS?
AWS container services provide a way to package and deploy applications with all of their dependencies, making them easy to move between environments. Containers offer many benefits over traditional virtual machines, including improved security, faster deployment times, and reduced operational costs.
Operational security is one of the key advantages of containers. By isolating applications in containers, you can limit the damage caused by a security breach. Containers also make it easier to deploy security updates, as you can update the base image and redeploy the updated container. This contrasts with traditional virtual machines, which can require significant downtime for security patching.
Containers also offer faster deployment times than virtual machines. This is because containers are typically much smaller than virtual machines, which can be deployed and started up much more quickly. In addition, containers are typically deployed on top of a lightweight operating system, such as Alpine Linux, which further reduces startup times.
Finally, containers can help reduce operational costs. AWS provides a range of services to help you start using containers. For example, Amazon Elastic Container Service (ECS) is a fully managed service that makes it easy to deploy, scale, and manage your container-based applications. ECS handles all the heavy liftings for you, so you don’t have to worry about provisioning servers or to configure networking and security settings.
Containers benefits in AWS
Containers are popular for developing and deploying microservices because they offer several benefits, including improved security, easier management, and portability. In addition, containers can be used to build scalable batch-processing applications and to standardize hybrid application code. They also offer an easy way to migrate applications to the cloud and can improve developers’ productivity. Let’s review all these benefits in more detail.
Build secure microservices
AWS allows you to build and deploy secure, fast, and scalable microservices. With containers, you can break your applications and run them as independent components (microservices). Every microservice package stores your application code and dependencies in a single image, making it easy to move them between environments. In addition, containers isolate your application from other applications on the same host, providing strong security isolation and performance. Finally, containers make it easy to scale your application by adding additional container instances as needed. Using containers, you can build secure, fast, and scalable microservices.
Batch processing is common in many applications, such as image processing, data mining, and log analysis. Batch jobs are typically long-running and resource-intensive, making them well-suited for containers. Containers offer several benefits for batch jobs, including isolation, portability, and scalability:
- Isolation is important for batch jobs because they can often be quite resource-intensive. By isolating batch jobs in containers, you can ensure that they do not impact the performance of other parts of your application.
- Portability is another key benefit of using containers for batch jobs. Packaging up the job and all its dependencies in a container allows you to move it to different platforms or environments. This can be helpful when you need to move a job to a different provider or want to run it on-premises.
- Finally, containers offer scalability for batch jobs. You can easily scale up or down the number of containers you are using based on the needs of the job. This can help you to cost-effectively provide the resources you need to get the job done quickly.
Scale Machine Learning (ML) models
There are many benefits to using containers when working with AWS. One of the primary benefits is that containers can help you scale your Machine Learning (ML) models more effectively. Using containers, you can launch multiple copies of your training data on different machines. This allows you to train your models faster and with greater accuracy. In addition, containers allow you to deploy your models more efficiently. You can launch multiple copies of your model on different machines, reducing the time and resources required for deployment.
Standardize hybrid application code
Containers help you standardize your hybrid application code and improve resource utilization by allowing you to package your application code with only its dependencies rather than making assumptions about the underlying operating system or hardware. This enables you to run the same code, unmodified, on multiple platforms, including Amazon EC2, Amazon ECS, Amazon EKS, AWS Lambda, and your on-premises servers. In addition, containers can improve the density of your applications by sharing a single kernel and isolating processes.
Migration to the cloud
Migrating applications to the cloud is a major undertaking for any organization, and it can be difficult to know where to start. One way to simplify the process is to use containers. Containers allow you to package application code and dependencies together without code changes, making it easy to move applications between environments. In addition, containers are isolated from each other so they can be run on the same host without conflict. This can help to reduce the cost of running applications in the cloud, as you can use fewer resources overall. As a result, containers can provide some benefits for organizations migrating to the cloud.
Developers are always looking for ways to be more innovative and efficient. One way developers have found to do this is through using containers. Containers allow developers to package their code and all its dependencies into a single, self-contained unit. This makes it much easier to move code from one environment to another and simplifies managing dependencies. Developers can also use containers to run multiple copies of their code in parallel on a single machine. This can lead to significant gains in performance and efficiency. As a result, containers have become an essential tool for many developers working in AWS.
