A reliable multicast network that preserves global order even during maintenance and doesn’t drop packets is not something you will find off the shelf.
A reliable multi-tenant multicast network also appears to be a rare beast. I’ve only heard of it in finance, and that’s only because it’s private and expensive and all the participants need to be generally nice to each other because it’s a repeated game and the operator can literally pull the plug if the rules are broken.
- pclmulqdq 3y agoDo you regularly allow untrusted machines onto your private pub/sub instances? I'm not sure the "operator pulling the plug" part is unique to the finance industry. Also, yeah, you have to do some engineering around your multicast distribution to make a pub/sub system, but multicast pretty much solves the data rate scaling problem - you are now basically O(1) in the number of connected subscribers.
- hinkley 3y agoThere was a time in the 00’s where a lot of server hardware had 3 NICs and you could use those for redundancy but a better use was to create three networks: inbound, service and database calls, and administrative. You had more control over your services talking to each other and control plane tech, thus could make some more guarantees than with inbound data. Don’t cross the streams.
