From SoundCloud's shift to Prometheus, a scalable, self-contained monitoring system built around a multi-dimensional time series data model, a flexible query language, dashboards via PromDash, and unified alerting with Alertmanager.

This blogpost discusses how SoundCloud implemented Prometheus as their monitoring system to overcome the limitations of their previous set-up and achieve a multi-dimensional data model, operational simplicity, scalable data collection, and a powerful query language.

SoundCloud teams with Concurrent Inc. to showcase how Scalding and Cascading accelerate data-driven pipelines, enabling rapid iteration and testing, with loose coupling and a nod to Spark.

SoundCloud's case study with Concurrent Inc. demonstrates using Scalding and Cascading to rapidly iterate data pipelines, test easily, and loosely couple data-processing workflows, with a nod to Spark.

SoundCloud's API transitions from XML to JSON with a phased deprecation plan and migration guidance for developers.

SoundCloud is deprecating XML responses in its API in favor of JSON, with JSON becoming the default on December 1, 2014 and explicit XML requests supported only until December 15, 2014, plus guidance on migrating to JSON and a JSON-to-XML proxy option for legacy apps.

The blogpost discusses the deprecation of XML responses in the SoundCloud API and provides details about the schedule.

Performance-driven refactor of SoundCloud's iOS waveform renderer, moving from CPU-heavy CoreGraphics drawing to GPU-accelerated, pixel-aligned animations and view-based masking to sustain 60fps playback.

Optimizes iOS waveform rendering by profiling and refactoring from CPU-bound CoreGraphics to GPU-accelerated CoreAnimation, using pixel-aligned masking and keyframe animations to achieve 60 FPS.
