How to Build QA at Scale Through Device Architecture

Let’s start with some absolutes. Maintaining a steady CI/CD pipeline is crucial to modern software development. Testing and quality engineering principles that drive solid deliverables should be flexible and agile. QA teams need hundreds of device and O/S combinations. With those non-negotiables in mind, how would you implement a flexible device architecture to support ongoing and evolving needs to assess mobile and web applications?

Beyond Data-Driven: How Today's Leading Retailers Are Leveraging Insights to Sell Better

Supply chain disruption continues to affect retailers, consumer packaged goods companies (CPGs), and customers. Constraints on the ability to produce goods have limited the availability of in-demand products, leading to inflation. Not only are manufacturers not making enough products in line with demand in industries such as automotive and electronics, at the same time, those products have become much more expensive.

Top 5 QR Code Generation Platforms

QR codes have entirely transformed how businesses connect with their customer base. These intriguing square-shaped codes house embedded information that can be effortlessly scanned using smartphones, directing users to specific websites, enticing landing pages, or irresistible promotional offers. The versatility of QR codes knows no bounds as they seamlessly integrate into many marketing campaigns, ranging from product packaging and print advertisements to innovative business cards and beyond.

A Deep Dive into Subscriptions with Absinthe

In this series, we've seen how to create GraphQL APIs in Elixir using Absinthe. So far, we have only discussed a one-way communication channel where the client makes the queries or mutations, and the server responds. GraphQL also supports a long-running subscription between the client and the server where the server can notify the client of events. This can be very useful in multi-user scenarios where many users might interact with the same resource at the same time.

Unlocking the Power of Programmable Data Planes in Kubernetes with eBPF #WordsUnplugged

In a recent article, Lakmal Warusawithana, Senior Director for Cloud Architecture at WSO2, wrote how programmable data planes offer dynamic control for cloud native applications and how technologies like the extended Berkeley Packet Filter (eBPF) and Kubernetes provide an abstraction to improve flexibility, scalability, and performance. In this WordsUnplugged episode, Lakmal, and Kanchana Wickremasinghe, VP and GM for Choreo at WSO2, sit down to talk about eBPF and its role in creating effective programmable data planes in Kubernetes. They also discuss benefits, challenges, best practices, as well as future trends and opportunities.

How to scale WebSockets to millions of connections

WebSockets are hard to scale, it's true. The stateful connection that makes them so powerful for two-way realtime communication also makes them tricky to load balance efficiently, but that isn't to say it can't be done. In this video, Alex Booker (@CodeCast) from Ably runs you through the technical challenges scaling WebSockets before outlining the patterns used to scale WebSockets to thousands of concurrent connections and beyond. Theoretically, the approach to system design outlined in this video can scale to millions of concurrent WebSocket connections in a production environment.
