In microservices architectures, apps are broken down into small, independent services that communicate with each other using APIs in a synchronous or asynchronous way.

Mobile device users care about three things when it comes to good app performance: We’re going to look at how modern concurrency APIs can help with some of these. We recently shipped a new profiling feature to help you find the sources of main thread contention; specifically detecting issues with image and JSON decoding or regex matching. These point you to spots where you can immediately make improvements to your app’s UI performance.

We are always trying to lower the barrier to entry when it comes to monitoring and observability and one place we have consistently witnessed some pain from users is around adopting and approaching configuration management tools and practices as your infrastructure grows and becomes more complex. To that end, we have begun recently publishing our own little example ansible project used to maintain and manage the servers used in our public Machine Learning Demo room.
