Introduction to Containers on AWS
AWS has many great technologies for application deployment, including serverless computing and containers. They allow DevOps teams deploy applications more quickly due to their cost-effectiveness. In some ways, the features of containers and serverless architectures can be compared. Serverless architectures are better for certain use cases. In these cases, containers work well.
The control plane is the entry point to running your container deployment on AWS. It is used to launch, check the status, or shut down an application. There are two control planes available to AWS:
Amazon Elastic Container Service, (ECS).
Amazon Elastic Kubernetes Service (EKS)
Let’s take a look at each one.
Amazon Elastic Container Service, (ECS).
AWS Elastic Container Service by AWS is a container orchestration platform that can scale. It is used for managing containers in a cluster. ECS is a fully managed, highly accessible, and highly scalable container control plan.
ECS can be used with EC2 instances, or AWS Fargate. AWS Fargate can be used as a serverless architecture.
Amazon Elastic Kubernetes Service (EKS):
EKS is an AWS service which provides and manages Kubernetes control aircrafts. It is more accessible with three masters in three availability zones.
EKS creates the Kubernetes API and control plane in your AWS infrastructure to run the application.
EKS allows workloads to be deployed using Kubernetes native tools like Kubernetes Dashboard and Kubectl.
EKS eliminates the need to operate, maintain, and install the Kubernetes control aircraft.
EKS can use plugins and tools developed by Kubernetes.
EKS automates parallel processing and load distribution.
FARGATE(serverless):
AWS Fargate allows you to run containers without having to manage the infrastructure. Fargate will be commanded by control-plane to run a container. Fargate handles all details. These tasks can be run on demand, according to a schedule, and without the need for an EC2 instance. Fargate allows you to pay only when the task runs.
AWS Fargate makes it easier for users to manage EC2 instances. Actually. Fargate will be the compute engine. Fargate allows users to focus on the elements of designing and building the application, rather than managing the infrastructure. Fargate lets you package your application in containers and specify the memory and CPU requirements. You can also define IAM policies and launch your application.
Similarities between ECS & EKS
ECS & EKS share the same layer functionality
EKS and ECS both have a layer of container concept called deployments (EKS), or tasks (ECS), and have similar features. ECS and EKS both have a concept called cluster, which is a combination all the components.
ECS & EKS both use AWS’s same compute platform
There are many options for computing in AWS to run containers with ECS or EKS.
A. EC2 instances – these are virtual servers in Elastic Cloud compute service from Amazon web service. This gives you more computing options. AWS Fargate: This service is available from AWS and can be used to run serverless applications.
Both services do not require monitoring or operating.
These services make it easier to manage services and allow users the freedom to concentrate on their applications. They are reliable and readily available. The control plane and other components will be available at all times for updating to the latest releases. There will be no downtime.
ECS & EKS share the same security options
All container services in AWS have the same security services, such as having appropriate IAM roles and policies. These services can only be used by a specific user and a group with the necessary permissions. This will not affect applications in the control plan from unknown users. You can grant access to a user in ECS & EKS for specific tasks or workloads.
