Michael Zhang Web Services (MZWS)

Welcome to MZWS!

Design Principles

• Onboarding should be simple. Download a binary / run a script, then add more servers / storage / as necessary. Configuration should be incremental, in that a basic setup will work and more features can be added with more configuration.

Requirements for setup

• Just a single machine: host services locally
• With an internal IP: serve to that IP
• With a public IP: automatic ACME certificates
• With more nodes: automatic consensus across the cluster
• With more storage: automatic CRUSH for S3

Features

Services:

• Object storage
  • Managed static websites
• Managed DB

Features:

• Manage collections of services
• ^Programmatically

Technical docs

Raft docs

• A node initially has no raft startup

Overall state consists of:

• A list of nodes, along with their UUIDs
• Which nodes are exit nodes, i.e hooked up to which public ports
  • The exit nodes will receive requests and forward them to others
  • TODO: For now, just a single load balancer. In the future, have others?
• Which nodes are available to run Docker services, and which services are running on which hosts

Assumptions

• All nodes can reach each other directly. This is either via public internet or a private net like Tailscale. Bastion systems are not supported.
