HN discussionBeing part of a team who is designing and running a globally distributed system has been the best 5 years of my 20 year tech career. Things go wrong sure, and it’s hard, but is crazy rewarding and intellectually challenging in all the right ways. I never quite got that when I was a full stack web dev. I wrote a post on what a distributed system engineer is, at least from our perspective at Ably Realtime. See https:/…

HN discussionHi - Matt's tied up atm, but I'll try and reply. (I'm also at Ably). > For the rest of us (think young startups, smaller shops) your costs may be prohibitive ( almost 6K / year) I'm afraid I don't follow that. We have a generous free tier (a lot of startups are fine just on that), and self service packages starting at $20/month. And very cheap overage pricing - $1.25 per million messages + $12.50 per 1000 peak concu…

HN discussionHey Sean, Matt here, co-founder of Ably. I have been meaning to write a blog post on this in fact, like I did some time back for ActionCable, see https://blog.ably.io/rails-5-actioncable-the-good-and-bad-pa... . I've not done an in-depth review yet, but from what I can tell SignalR has the following shortfalls: - It relies on a single message bus for message passing between nodes. If your rate of messages exceeds wh…

HN discussionFascinating and brilliant article! We have a similar approach to health in our distributed messaging platform in that during situations where there are capacity problems, we ensure existing connections and requests continue to get serviced, yet new requests are rejected triggering a fail over to other regions. We effectively put the affected nodes into an “under siege mode” until the load subsides. Interestingly, in…
