To recap, adopting a microservices architecture has allowed us to regain team autonomy by breaking up our monolithic backend into dozens of decoupled services, each encapsulating a well defined portion of our product domain. Every service is built and deployed individually, communicating with other services over the network via light-weight data interchange formats such as JSON or Thrift. What we haven&#39;t touched on so far is how a microservice at SoundCloud looks backstage.</p> <p><a href="/blog/inside-a-soundcloud-microservice" class="readmore">Read more...</a></p> Fri, 28 Jul 2017 00:00:00 +0000 https://developers.soundcloud.com/blog/inside-a-soundcloud-microservice https://developers.soundcloud.com/blog/inside-a-soundcloud-microservice.rss Lessons in resilience at SoundCloud <p>Building and operating services distributed across a network is hard. Failures are inevitable. The way forward is having resiliency as a key part of design decisions.</p> <p>This post talks about two key aspects of resiliency when doing RPC at scale - the circuit breaker pattern, and its power combined with client-side load balancing.</p> <p><a href="/blog/lessons-in-resilience-at-SoundCloud" class="readmore">Read more...</a></p> Wed, 07 Dec 2016 00:00:00 +0000 https://developers.soundcloud.com/blog/lessons-in-resilience-at-SoundCloud https://developers.soundcloud.com/blog/lessons-in-resilience-at-SoundCloud.rss Microservices and the monolith <p><a href="https://developers.soundcloud.com/blog/building-products-at-soundcloud-part-1-dealing-with-the-monolith">In a previous series of blog posts</a>, we covered our decision to move away from a monolithic architecture, replacing it with microservices, interacting synchronously with each other over HTTP, and asynchronously using events. In this post, we review our progress toward this goal, and talk about the conditions and strategy required to decommission our monolith.</p> <p><a href="/blog/microservices-and-the-monolith" class="readmore">Read more...</a></p> Fri, 26 Aug 2016 00:00:00 +0000 https://developers.soundcloud.com/blog/microservices-and-the-monolith https://developers.soundcloud.com/blog/microservices-and-the-monolith.rss
