keepAlikeepAliveTimeout

The keepAliveTimeout in a NestJS application (or any Node.js application) is a crucial configuration setting that controls how long an idle connection is kept open before it is closed. Understanding keepAliveTimeout and its implications can help you configure your server for better performance and stability, especially when dealing with long-running requests or integrations with load balancers.

1. What is keepAliveTimeout?

  • Definition: The keepAliveTimeout is a setting on the HTTP server that specifies how long to keep an idle connection open before closing it.
  • Idle Connection: An idle connection is one where no data is being transferred between the client and the server after the initial request has been fulfilled.

Virtual Machines vs. Containers

Virtualization Level

Virtual Machines (VMs)

  • Utilize hardware virtualization.
  • Rely on a hypervisor to virtualize physical hardware resources (processors, RAM, storage, network cards).

Containers

  • Use operating system-level virtualization.
  • Built upon the host OS's kernel, allowing multiple containers to run on a single OS instance.
