Want to solve overmonitoring and alert fatigue? Create the right incentives

January 15, 2020

Keeping your signal-to-noise ratio high is a nontrivial problem. Modern tools make it easy to overmonitor (which leads to noise). The result? Missed alarms and unhappy customers. Filtering the noise is not the answer. Kishore Jalleda explains how Yahoo reduced the alert volume from ~200K a month to a few hundred by creating the right incentives and culture.

Watch out! The nanoservices are comIng.

January 15, 2020

Welcome to the world of nanoservices: smaller than a microservice, bigger than a function, they are the perfect unit of software. Nanoservices are flexible, manageable, and scalable and a great way to do serverless computing. Matthew Clark explains how to get nanoservices right, drawing on his experience at the BBC, which now has over a thousand in production.

Why an (interactive) picture is worth a thousand numbers

January 15, 2020

Feeling overwhelmed by huge amounts of data has become the norm. Creating effective visual representations of data offloads some of the work of quickly finding interesting patterns to our powerful perceptual system. Miriah Meyer explores the role that interactive visualizations can play in helping us find meaning in mounds of data and discusses the limitations of this approach.

Adventures in accidental human architecture

January 14, 2020

Are you vigilantly keeping watch on your system in anticipation of altering some setting or system state? When parts of your system fail, do you perform manual cleanup? If so, humans have been injected into your architecture. Michelle Brush explores the factors that lead to systems that run on human intervention and shares best practices for detecting and removing humans from the machine.

Apache Spark and machine learning on microservices

January 14, 2020

Architect as storyteller

January 14, 2020

Nathaniel Schutta explains why an architect's job is to be a storyteller. Architects are essentially the Rosetta Stone of an organization, providing translation services (or, as some would call it, the "elevator" between the executive suite and the development floors). The challenge lies in not only crafting a compelling message but doing so for wildly disparate audiences.
