Amazon EKS gRPC Application Deployment with Application Load Balancer

This example shows how to run a gRPC-based application on Amazon EKS (a managed Kubernetes service) and expose it using an Application Load Balancer (ALB). Amazon EKS hosts your Kubernetes applications without having to host servers. The Application Load Balancer is in front of your applications and accepts incoming requests and sends them to the appropriate location.

In this setup, your backend services are in private subnets, so they're not directly exposed to the internet. Public subnets handle incoming traffic, and a NAT Gateway gives your backend managed access to the internet when it requires updates or outside connections.

It's all built to interact and operate together to enable a reliable and safe environment for your gRPC services.

Why is the template a game changer? 

It takes a lot of effort and time to implement gRPC services on the cloud from the ground up. You have to implement networking, scalability, load balancing, and security yourself. If you do it incorrectly, your system might turn out to be slow, expensive, or even insecure. This template spares you all that trial and error.

•  It is scalable. Your system removes or adds resources automatically with an Auto Scaling Group depending on traffic.

• It is safe. Your service operates within private subnets and encrypts data using SSL/TLS encryption.
• It is efficient. The Application Load Balancer understands gRPC over HTTP/2, so it forwards requests smoothly.

Rather than wasting days creating the architecture, you can begin with this pre-existing template and work on your application.

Who can use this template and when? 

This template will be useful to anybody who would prefer to run gRPC-based applications on Amazon EKS.

• If you are developing microservices requiring secure, high-speed communication, this is for you.
• When you are migrating your application from on‑premises servers to the cloud, this provides you with a ready template.
• If you are embarking on a new cloud-native project and wouldn't prefer to make errors, this will save you time.

When you would use this template is at the start of your project when you are planning or in the act of configuring your infrastructure. It can also be helpful down the line if you want to upgrade your existing setup to comply with best practices.

What are the main components of the template? 

Below is a summary of every section:

• Amazon EKS: A managed service to execute Kubernetes without having to operate servers yourself.
   
• Kubernetes Nodes: The servers that your gRPC app is hosted on.
   
• gRPC Server Pod: The deployed gRPC application in Kubernetes.
   
• Application Service: A Kubernetes service to manage the gRPC traffic within the cluster.
   
• Application Load Balancer (ALB): A load balancer that sits in front of your backend services and accepts requests from end-users.
   
• Target Group: A collection of backend pods to which traffic is routed by the ALB.
   
• Auto Scaling Group: Automatically scales up or down the nodes depending on traffic.
   
• Internet Gateway: Allows your public subnets to access the internet.
   
• NAT Gateway: Provides your private subnets with an internet connection without exposing them.
   
• Public Subnet: Manages incoming and outgoing internet traffic.
   
• Private Subnet: Protects your backend services, beyond direct reach.
   
• SSL/TLS Encryption: Encrypts data as it travels over the network.
   
• Monitoring and Logging: Monitors requests and provides performance information.
   
• Route 53 DNS: Resolves domain names and enables services to query one another.
   
• Security Groups: Define which traffic can come in or go out.

All these components come together to form a system that is secure, reliable, and scalable.
