  • Best alternatives to Heroku in 2026
    Fly.io opens up two things Heroku keeps at arm's length: real multi-region deployment and full control over the runtime. Heroku's Common Runtime offers two regions (US and EU), and Private Spaces gets you one region at a time from a wider list. Fly runs Firecracker microVMs across eighteen regions on six continents, and replicas can be pinned to specific cities. If your Heroku app has global users and you've been... - Source: dev.to / about 1 month ago

  • From Netdata Inspiration to SaaS MVP: Server Monitoring with Bun + Claude Code Opus 4.6
    If you've ever set up Netdata, you know that feeling โ€” hundreds of real-time charts, per-second granularity, metrics you didn't even know your kernel exposed. It's a wonderful piece of software, genuinely one of the best open-source monitoring tools out there. - Source: dev.to / 4 months ago
  • Trying to decide best practices for production environment
    Pros are instant HA and Migration. Cons are huge bandwidth hits. With your 4x1gbe you would be maxed out on replicating those 25 VMs. You wouldn't have anything for users. I have a test lab with 4 nodes, 22cpu 100gbram and 30tb space, using low end stuff, 12hdds. Proxmox, ceph dashboard, (the native ceph dashboard you can turn on), and a netdata.cloud account. So I watch it like a hawk and like to load test. Source: over 3 years ago
