A data contract is a formal agreement between an upstream component and a downstream component on the structure and semantics of data that’s in motion. In a previous post, I showed how Confluent Schema Registry supports data contracts. By combining data contracts and encryption on streaming workloads, you can shift left the responsibility of data consistency, quality, and security to the producer, allowing the consumer to depend on a trustworthy stream of data.

When it comes to data-driven applications, developers and data engineers are always trying to balance factors such as scalability, speed, flexibility, latency, and availability. In other words, databases and infrastructure are the foundations for well-structured applications: just like bricks are for houses. This article explores Redis' data store features and includes use cases. We'll learn how to use Redis in Python with a step-by-step tutorial. Let's get started!

Today, we're thrilled to announce the public preview of Light Sleep. Waking up from Scale-to-Zero is now imperceptible for CPU workloads with sub-200ms cold starts. A few months ago, we announced the first iteration of Scale-to-Zero on the platform to reduce idling costs. With Scale-to-Zero and Autoscaling, apps sleep and wake up automatically on demand based on requests, and scale out horizontally according to your criteria.

How to make your enterprise data accessible, usable, and insightful.

Automation testing is now the default for modern QA teams. Instead of spending hours manually clicking buttons, filling out forms, and triple-checking for bugs (only to miss one in production), testers can write a script once, and the machine takes over. It can mimic the user’s actions, flags issues, and gives teams back hours that they can use for more strategic tasks. When done right, automation testing is a game-changer.

APIs are the backbone of modern applications. They connect services, share data, and power almost every feature you see in a web or mobile app. As software becomes more complex, QA teams rely on web service testing tools to make sure APIs work as intended. These tools help you validate functionality, performance, and security while speeding up test creation and execution. With so many API testing tools available today, choosing the right one can feel overwhelming.

Today, we're going to have a little history lesson for those of you who haven't been around since forever, but for those of you who have been around since forever, hopefully this will be a nostalgia fest. We can enjoy some good memories together. From FTP to Kamal, an oral history of deploying Rails apps. Watch the video for the full story!

Record sessions in the background: Multiplayer saves recordings the moment bugs or anomalies occur, making it effortless to capture elusive, hard-to-reproduce problems. Most session recording tools force you into a tradeoff.

Chatbots have quickly moved from novelty to necessity. With over 987 million users and platforms like ChatGPT receiving more than 4.6 billion monthly visits, chatbots are now core to how people interact with digital products.

Solo.io Gloo Gateway gives teams a reliable way to secure, route, and monitor API traffic in real time. With its high-performance Envoy core and Kubernetes-native design, it meets the demands of distributed applications and modern service architectures. However, performance metrics alone don’t reveal how developers engage with your APIs or why adoption stalls.
