Access Container Applications Privately on Amazon ECS

Using Amazon ECS, AWS Fargate, PrivateLink, and a Network Load Balancer (NLB), this professionally created template shows a private, containerized application architecture. Direct exposure to the public internet is avoided by ensuring that all traffic remains within AWS's private network.

From ECS service discovery to VPC endpoint setups, this template offers a strong foundation for running safe, serverless apps. Companies emphasising security, compliance, and internal network integrity will find it perfect.

Why Is This Template A Game Changer?

The reasons behind this template's game-changing are as follows:- 

• No more public internet exposure: Traffic is routed exclusively through VPC endpoints and private subnets, reducing the attack surface significantly.

• Built-in compliance: Suitable for regulated industries that require private connectivity (e.g., finance, healthcare, government).

• Serverless flexibility: Uses AWS Fargate, so you can run containers without managing servers.

• Seamless scalability: Integrated Auto Scaling Policies ensure optimal performance without human involvement.

• Plug-and-play security: Includes IAM roles, security groups, and CloudWatch monitoring out of the box.

With this template, you can confidently deploy and manage Amazon ECS private access, ensuring both performance and peace of mind.

Who Needs This Template—and When To Use It?

This template is perfect for: 

• Enterprises creating secure microservices in AWS.

• Startups developing internal tools or backend services that shouldn’t interact with the public internet.

• DevOps teams want to use container security best practices.

• Compliance-focused teams use a private connection for sensitive workloads.

• Anyone using ECS but is uncertain how to properly set up PrivateLink, NLB, or Fargate for private deployment.

Use it when: 

• You're launching internal programs that don’t need public access.

• Your legacy workloads are being moved to a containerized setup.

• You need a fast, visual way to model a secure ECS deployment using Cloudairy.

What Are The Main Components of The Template? 

Every component has been selected with great care to provide safe, scalable, and private application delivery:

• VPC Endpoint – Allows private connections to AWS services.

• Amazon ECS – Organising your containerized apps.

• AWS Fargate – Offers serverless computing for containers.

• Network Load Balancer (NLB) – Manages high-performance, low-latency internal routing.

• Private Subnet – Separates workloads from the public internet.

• Internet Gateway – Optional; only used when external access is expressly necessary.

• VPC Security Groups – Enforce traffic rules and network security.

• AWS PrivateLink – Sets private, secure communication between systems.

• Route Tables – Directs network traffic within your VPC.

• IAM Roles and Policies – Define permissions and access controls.

• CloudWatch Metrics – Offers real-time information into performance and reliability.

• ECS Task Definitions – Blueprint for how containers are deployed.

• Application Load Balancer (ALB) – Distributes internal application traffic efficiently.

• Elastic Container Registry (ECR) – Offers a safe repository for container images.

• Auto Scaling Policies – Dynamically scale your services to meet demand.

Combining these elements produces a very safe and effective design for Amazon ECS private access.
