Container use is growing fast across a wide range of design use cases, but it is not a simple plug-and-play solution. Adopting containers becomes quite challenging, especially when it comes to executing them at scale because most businesses have very limited resources.
Top businesses choose K8s because they believe they will help break down container adoption barriers. Kubernetes is the first step in creating scalable contemporary apps, according to several leading businesses. As per the research, 83% of enterprises use Kubernetes as their container orchestration solution, compared to 24% who use ECS, according to a study.
Spotify has seen considerable cost savings thanks to Kubernetes, as this case study shows. The orchestration capabilities of K8s have resulted in 2-3x higher CPU usage, which has improved expenditure optimization.
The Google-developed and Cloud-hosted Kubernetes container orchestration solution also makes use of Docker to run. The fact that Kubernetes has a significant community deserves attention.
On the other side, scaling up apps is made possible via Amazon ECS, a container orchestration platform. As demand grows, it continuously adds more containers to run the application operations.
Both technologies have good and bad points when used, making it crucial to study them before selecting one based on your company's needs.
What Is Kubernetes?
Kubernetes is an open-source platform for container orchestration, a container workload management system that was created by Google, and is widely used by businesses. One of the main advantages of Kubernetes is its ability to automate rollbacks for containerized apps, as well as cluster self-healing, secrets, and configuration management.
The above diagram describes, that there are several components associated with a Kubernetes cluster. The master node places container workloads in user pods on worker nodes or itself. The other components include:
- etcd: Using a simple HTTP or JSON API, the Kubernetes master's API Server may retrieve the configuration data that is stored in this component.
- API Server: The Kubernetes master node's management hub is defined by this component. It makes communication between the various parts faster, ensuring the cluster's health.
- Controller Manager: By scaling workloads up and down, this component makes ensuring that the clusters' desired state matches their existing state.
- Scheduler: The task is assigned to the proper node by the scheduler.
- Kubelet: The API Server sends these component pod specifications, and it manages the pods that are currently running on the host.
Further, Kubernetes-related terms are included in the list below:
- Pods: Containers are deployed and scheduled by Kubernetes in groupings known as pods. A pod is a collection of containers that operate on a single node and share IP addresses, filesystems, and kernel namespaces.
- Deployments: You can design and control a collection of pods using these building elements. To scale horizontally or to guarantee availability, deployments can be utilized with a service tier.
- Services: Kubernetes will automatically round-robin requests to and from services. These are endpoints that can be addressed by name and can be connected to pods using label selectors. Services are the "external face" of your container workloads in Kubernetes.
- Labels: These are object-attached key-value pairs. They may be used to update and search a collection of related things.
What Is ECS (Amazon Elastic Container Service)?
A container orchestration service called Amazon Elastic Container Service (ECS) is used to scale, deploy, and manage containerized applications. Through API calls and task definitions, ECS enables developers to install and manage scalable applications that are operating on a collection of machines known as Clusters.
As per the above diagram described, the tasks that run in Docker containers and container instances are just two of the many components that make up an ECS cluster. Some AWS services that frequently work with ECS are listed below:
- Elastic Load Balancer: Traffic may be directed to containers via this component. There are two types of load balancing: application and classic.
- Elastic Block Store: For ECS tasks, this service offers persistent block storage (workloads running in containers).
- CloudWatch: Metrics from ECS are gathered by this service. Scaling up or down ECS services is possible based on CloudWatch measurements.
- Virtual Private Cloud: Within a VPC, an ECS cluster functions. There may be one or more subnets in a VPC.
- CloudTrail: ECS API calls can be recorded by this service. The type of request made to Amazon ECS, the originating IP address, the user's information, and other facts are collected
- State Engine:: The state engine is made to keep track of running containers, available hosts, and other cluster managers' duties. Many EC2 container instances and containers may be found in a container environment. It is vital to monitor the availability of instances to fulfill new requests depending on CPU, memory, load balancing, etc.
- State Engine: To deploy containers in the best EC2 container instances, these components leverage data from the state engine. For jobs that run for a brief period of time, the batch job scheduler is employed. Long-running applications take advantage of the service scheduler. It has the ability to automatically add new tasks to an ELB.
- Cluster: An AWS region's logical placement border for a group of EC2 container instances is represented by this. A cluster may scale up and down dynamically and span several availability zones (AZs). There may be two clusters in a dev/test environment: one for production and one for testing.
- Tasks: Work is divided up into tasks. Container locations are specified in task specifications that are expressed in JSON (on an EC2 container instance). Despite the fact that jobs typically only comprise one container, they occasionally do.
- Services: The number of tasks that should be active simultaneously throughout a cluster is specified by this component. The service scheduler may be used to put tasks and you can communicate with services via their API.
ECS - an Amazon service, is made up of multiple integrated parts that let administrators build tasks, services, and clusters:
Due to vendor lock-in, it should be noted that ECS exclusively controls ECS container workloads. Running containers on infrastructure other than EC2 is not supported, including physical hardware and alternative clouds like Google Cloud Platform and Microsoft Azure. Of course, the benefit is having access to all of the other AWS services, like Elastic Load Balancers, CloudTrail, CloudWatch, etc.
