How Workers VPC Services connects to your regional private networks from anywhere in the world
In April, we shared our vision for a global virtual private cloud on Cloudflare, a way to unlock your applications from regionally constrained clouds and on-premise networks, enabling you to build truly cross-cloud applications.
Today, we’re announcing the first milestone of our Workers VPC initiative: VPC Services. VPC Services allow you to connect to your APIs, containers, virtual machines, serverless functions, databases and other services in regional private networks via Cloudflare Tunnels from your Workers running anywhere in the world.
Once you set up a Tunnel in your desired network, you can register each service that you want to expose to Workers by configuring its host or IP address. Then, you can access the VPC Service as you would any other Workers service binding — Cloudflare’s network will automatically route to the VPC Service over Cloudflare’s network, regardless of where your Worker is executing:
export default {
async fetch(request, env, ctx) {
// Perform application logic in Workers here
// Call an external API running in a ECS in AWS when needed using the binding
const response = await env.AWS_VPC_ECS_API.fetch("http://internal-host.com");
// Additional application logic in Workers
return new Response();
},
};Workers VPC is now Continue reading
