Why Segment Went Back to a Monolith
Are there any case studies where microservices went well?<p>From an end user perspective, Netflix runs in “constantly degraded” mod.<p>From an engineering perspective, they track “number of successful stream starts”, instead of percentage of the time 100% of their services are working.  That’s a huge red flag.<p>As a researcher, the monitoring and fault-propagation &#x2F; modeling work they’ve done to get it to stay up at all is impressive, but it’s not clear all of that tooling would be necessary if they didn’t have to reason about N^2 fault tolerance scenarios, where N = 100’s of microservices.  That’s on the order of one fault tolerance scenario for each atom in the universe.
