Adam Onishi walks you through the project from design to deployment, covering design considerations, font choices, frontend optimization, and performance testing before exploring how service workers can improve performance.
Kubernetes and Prometheus are still pretty young, but somehow they immediately fell in love when they first met early last year. And now Prometheus has moved into the shiny new CNCF building that Kubernetes has called home for a while. Björn Rabenstein explores how the first two projects hosted by the Cloud Native Computing Foundation work together.
Everything changes at scale. Launching products at a scale of 1+ billion users requires a massive cross-team, cross-functional, coordinated effort, and business, engineering, and cultural challenges must be overcome. Kishore Jalleda and Gopal Mor explain how they have applied DevOps best practices at scale to successfully launch several high-profile products at Yahoo.
The elephant in the room that every developer ignores is that all automated tests (except unit) are too slow for today’s fast-paced, first-to-market environment. With slow automated tests, you’re just shipping problems faster to production. Emanuil Slavov explains how the team at Komfo made automated tests run 60x faster using containers, hermetic servers, and improved architecture.
New Direction - Velocity & Fluent
Successful DevOps means empowering teams. But you still have things you want all teams to do, and you need to balance the benefits of the right technologies against the costs of running multiple data stores, deployment platforms, languages, etc. Sarah Wells offers a brief overview of nudge theory and explores its possibilities for influencing disparate teams to do things for the common good.
Loading all the resources a web page needs is a complex process. Some resources can cause the browser's parser to block, preventing other resources' discovery. In other cases, resources can be hidden from the parser altogether. Yoav Weiss discusses how browsers discover and load resources and explores preload, a new link relation enabling early resource discovery.
There's more to microservices than just being small. Modern service-oriented architectures typically reside in more volatile environments, and the lifespan of a single service instance is much shorter than it used to be. Rick Fast explores how to design services and their infrastructure to allow for dynamic placement, resiliency, monitoring, and discovery.
Who do you trust? What do you control? What are your dependencies? Reliability on the Internet is an adrenaline-fueled adventure, but we all want a good night sleep and working service sometimes. Adam Surák takes a closer look at some reliability nightmares and explains how they could be dealt with.
Several APIs are available on modern browsers to help performance, including Service Worker, Push Notifications, NetInfo API, the Cache Storage API, and the older Application Cache. Through hands-on labs, Maximiliano Firtman walks you through using these APIs to create a progressive web app and improve performance and perception on a website.
New performance bottlenecks become apparent as web browsers and servers start using HTTP/2. Kazuho Oku explains the issues, their mitigation, and how the developers of the HTTP protocol are trying to make the Web even faster, covering the reality of HTTP/2 prioritization, cache-aware server push, the impact of load balancers for HTTP/2, mobile optimization, and HTTP caching.
