Gateway Attachments for High Throughput EC2 Inference Endpoints

Question

Pulumi · Accepted Answer

To create Gateway Attachments for High Throughput EC2 Inference Endpoints using Pulumi, there are few steps we need to take. The 'gateway attachment' refers to the process of hooking up a VPC with a component that allows traffic to flow in or out of it. Below are the components we might need to set up:

1. **Internet Gateway**: To allow communication between instances in your VPC and the internet.
2. **Virtual Private Gateway**: To establish a VPN connection between your VPC and your own networks.
3. **Transit Gateway**: To connect VPCs and on-premises networks through a central hub.

The inference endpoints, which you might be setting up using AWS EC2, will require a VPC with potentially an internet gateway for access to internet-based resources and services. The high throughput requirement suggests that you might consider ensuring your network configurations (like route tables and Network ACLs) are optimized for high bandwidth.

We will use `aws.ec2.Vpc` to create a new VPC, `aws.ec2.InternetGateway` to create an internet gateway, and `aws.ec2.VpcGatewayAttachment` to attach the internet gateway to the VPC:

Here's a program that sets up a VPC with an Internet Gateway attachment for high throughput EC2 inference endpoints:

```python
import pulumi
import pulumi_aws as aws

# Create a new VPC for your inference endpoints
vpc = aws.ec2.Vpc("high-throughput-vpc",
    cidr_block="10.0.0.0/16",  # Change to your preferred CIDR block
)

# Create an Internet Gateway
igw = aws.ec2.InternetGateway("high-throughput-igw",
    vpc_id=vpc.id
)

# Attach the Internet Gateway to the VPC
igw_attachment = aws.ec2.VpcGatewayAttachment("high-throughput-igw-attachment",
    internet_gateway_id=igw.id,
    vpc_id=vpc.id
)

# Output the VPC and Internet Gateway IDs
pulumi.export('vpc_id', vpc.id)
pulumi.export('igw_id', igw.id)
```

In this program, we're accomplishing the following:
- We create a new VPC where your EC2 instances for inference will reside, using a CIDR block that you can configure according to your network design.
- Next, we create an Internet Gateway. This is necessary if you want instances in your VPC to communicate with the internet, which could be useful if you're downloading models or data from the internet onto your EC2 instances.
- Finally, we attach the Internet Gateway to your VPC. This attachment is what enables the traffic to flow between your VPC and the larger internet.

This setup would be the minimum for creating an environment where you could deploy high throughput EC2 inference endpoints that can access the internet. If you need connectivity to other VPCs or on-premises networks, you'd likely add in a Transit Gateway setup here as well. For High Throughput specifically, you might need to consider AWS's Enhanced Networking features and ensure the EC2 instance sizes you choose support the bandwidth you require.

Remember to replace the 'cidr_block' with your desired IP range, and configure additional settings like subnetting and route tables as required for high throughput.
