We spoke to engineers at LinkedIn, Slack, and Box who'd already built realtime infrastructure themselves. They told us it would take non-trivial upfront engineering with significant operating costs. Building on Ably was the only logical choice: we bypassed a hefty DevOps debt and rapidly shipped our new feature flag streaming capabilities while keeping our architecture simple and reliable.
