AWS EKS vs ECS: Comparing Two Best Container Solutions

Cloud computing and storage containerization help companies manage their applications and services competently and efficiently. They are the foundations of agile and scalable solutions in modern application development and deployment.

Implementing a container orchestration platform is critical to ensuring high operational efficiency and agility while implementing cloud-based application and service management.

Amazon Web Services (AWS) is a leading cloud-based solution firm. It gives two well-known container orchestration solutions: Amazon Elastic Kubernetes Service (EKS) and Amazon Elastic Container Service (ECS).

These services handle companies’ complicated requirements, giving stable foundations for running containerized applications. This article compares AWS EKS and ECS, the popular container orchestration solutions today.

What is AWS EKS?

Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service provided by Amazon Web Services (AWS). It offers the same automation and optimization benefits as other AWS-managed services.

AWS’s wholly managed EKS cluster solution aims explicitly to reduce the complexity of cluster deployment, management, and scaling of Kubernetes. It provides an entire control plane stack, eliminating the need for Kubernetes’s underlying infrastructure.

In short, using AWS EKS allows the user to run Kubernetes without worrying about stressing bits like configuring or maintaining the control plane nodes. Such an approach guarantees the availability of the Kubernetes control plane, the installation of security patches, and updates.

This leaves users with purely administrative responsibilities and allows them as much time as they need to tune their applications and achieve goals strictly related to application development. Users still manage their worker nodes, where their containerized applications run, but EKS connects to the AWS services easily.

Users follow features like load balancers, auto-scaling groups, and security groups to optimize and improve the usability of their Kubernetes applications. If organizations need to use the power of Kubernetes to ease the complications caused by acquiring and managing infrastructure, then the AWS EKS would be a fascinating solution.

By simplifying the cloud-native journey and making developers and innovators the heroes, EKS improves their productivity and user experience through a fully managed Kubernetes control plane and ease of integration with AWS services.

What is AWS ECS?

Amazon Elastic Container Service (ECS) is a fully managed container orchestration service that Amazon Web Services (AWS) delivers. Its primary purpose is to simplify the deployment of Docker containers and management strategies.

With ECS, the user can integrate the container applications without bothering with the underlying infrastructure.

ECS provides developers without knowledge of server administration with a high level of abstraction, freeing them from complicated server management details and allowing them to focus on application delivery and development.

AWS ECS has several notable features, including the ability to specify the needed task configurations, create clusters for managing tasks or instances, establish services for maintaining a specified number of task instances running, and easily integrate with other AWS services such as load balancers and autoscaling. 

ECS’s main specialization seems to be container orchestration, not only Kubernetes, which AWS EKS provides. On the other hand, ECS makes it easier for the containers to communicate and share information, which is how the microservices structures are deployed and managed.

Differences: ECS vs EKS AWS

One must be aware of the critical differences between AWS ECS and EKS (the container orchestration systems offered by AWS). While both share similar goals, the differences mentioned earlier should be considered when managing a containerized workload.

Let’s delve into the differences between Amazon EKS vs ECS:

Platform Integration

• AWS ECS: Because ECS is an intrinsic AWS service, it can integrate with the AWS load balancer, AWS Fargate, and AWS RDS via ECS. The operator’s surroundings do this and reduce the deployment processes and management tasks.

• EKS: Given Kubernetes, EKS allows flexible application management by running both on-premises and in the cloud. So, unlike ECS services provided by AWS and ready to use, open-source services require more effort.

Scalability

• AWS ECS: ECS is outstanding in terms of scalability and handles the scaling of apps automatically, depending on the level of demand. Whether pay-for-usage mode (AWS Fargate) or instance-based mode (EC2), it enables them to have scalability options.

• EKS: EKS is scalable, but it requires a more hands-on approach. Running online campaigns for a brand in a competitive market is much more dynamic than traditional marketing, requiring a proactive and adaptable approach. Manually configuring and activating autoscaling groups and the Horizontal Pod Autoscaler of Kubernetes is obligatory, which may complicate and add to the difficulty of using ECS.

Security

• AWS ECS: ECS utilizes the security features incorporated into the AWS platform, keeping in mind IAM(Identity and Access Management) roles that allow you to perform tasks, security groups, and VPC network isolation.

• AWS EKS: EKS heavily relies on Kubernetes’ unmined native security capabilities, such as RBAC, Network Policies, Secret Management, etc. However, integrating the additional resources is a complex task that may create issues, as the learning curve can get steep for other teams.

Pricing Models

• AWS ECS: Pricing is based on resource consumption such as vCPU and memory without additional charges for ECS.

• EKS: EKS charges a flat fee for each EKS cluster alongside resource consumption costs. While cost-effective for smaller projects with fewer clusters, it might be pricier for larger organizations with multiple clusters.

Complexity

• AWS ECS: As a native AWS service, ECS is generally easier to set up and manage. It integrates well with AWS management tools and reduces operational complexity.

• EKS: Based on Kubernetes, EKS requires a deeper understanding of Kubernetes. It adds complexity to managing and operating applications. While providing more control and flexibility, it entails a steeper learning curve.

Container Orchestration Approach

• AWS ECS: ECS is built on a task-based hierarchy, which manages containers grouped into tasks as whole entities. This allows containerized application deployment and management to be streamlined as container clustering complexity is hidden.

• EKS: Similarly, EKS reflects the pod-sourced container orchestration of its Kubernetes parent. These containers are grouped inside pods, the base units of deployments. Instead of images, they use containers for application scheduling and networking, provided by part control but sometimes add complexity.

Community Support and Ecosystem

• AWS ECS: Being very tightly coupled, it is advantageous for ECS to integrate AWS services, but the Kubernetes community and ecosystem may be more significant in comparison. Meanwhile, ECS users can still rely on the support of a wide range of Docker ecosystems and toolings.

• EKS: EKS utilizes its extensive and dynamic nature through a rich Kubernetes community and ecosystem. This encompasses many third-party projects, tools, plugins, and communities, providing vast options to widen and customize Kubernetes deployment functionality.

Portability and Vendor Lock-in

• AWS ECS: ECS may lock vendors in because it can be used with a few AWS services. While it provides a smooth experience inside the AWS ecosystem, migrating ECS workloads from other cloud providers or on-premises to AWS may involve much work.

• EKS: EKS yields additional portability since it is built on Kubernetes, an open-source platform backed up and supported by different cloud vendors and on-premises environments. This results in a process that can be run anywhere with Kubernetes without any lock-in concerns on any vendor.

AWS EKS vs ECS Performance Comparison

When evaluating AWS EKS and ECS performance, the distinction lies in the trade-offs between managed services and self-managed infrastructure. EKS brings about convenience and simplicity with the assistance of ineffectiveness.

It is taking away complexities that lead to doing away with issues of infrastructure management that ultimately simplifies the operations and reduces the workload.

Nevertheless, ECS offers a broader range of control and customization settings, allowing users to fine-tune their infrastructure and find the best performance according to their specifications.

Fully Managed Cluster (AWS EKS):

The AWS EKS is a managed service, so users fully comprehend the underlying infrastructure. This approach has profound advantages, which can be easily noticed in businesses that lack the expertise or resources to manage their clusters perfectly.

Through AWS’s role as the infrastructure management authority, developers can concentrate on their applications and innovation while operational challenges can be operated in the background.

One of the principal advantages of EKS is operation automation, which is concerned with cluster management and efficiency.

Automatic scaling features empower the cluster to be ready for edge traffic, automatically scaling the resources needed based on demand without manual intervention.

Furthermore, node auto-discovery and cluster health checking support reliability and availability, minimize downtime, and reduce the operation burden.

Self-Managed Cluster (AWS ECS):

Unlike ECS, which is a self-managed service and the user is solely responsible for infrastructure maintenance, AWS ECS works on a self-managed basis.

Such a task sounds intimidating for organizations lacking the technical knowledge or experience to implement the whole system. At the same time, doing everything by yourself gives you the lever of control that you might not have with fully managed solutions like EKS.

ECS focuses on self-management, which lets users handle the procedures for personalizing their cluster regarding performance and operation understanding.

In contrast to EKS, ECS users are in charge of the version of Kubernetes they want. Thus, they can make their k8s versions compatible with a particular application dependency or feature.

Moreover, users can use their infrastructure on-premise or in the cloud. This allows them to have more customization options at a lower operating cost.
