Among the many new features introduced in Grafana 7.0, one of the most exciting ones is transformations. The concept of data transformation is not new to Grafana, but prior to Grafana 7, it was fairly rigid and available only in the Table panel.
Lambda is an AWS service that allows you to run your code completely in the cloud without the need for on-prem servers. As the world has shifted away from on-prem and toward serverless computing, Lambda has grown in popularity: 1700 companies report using Lambda as part of their data infrastructure in StackShare.
Developers make fun of legacy systems because we're scared of them. We're afraid that the tiniest change will cause the app to break in unexpected ways. We're afraid we won't realize it until a customer complains. One way to combat this fear is through testing. In this article, José Manuel shows us how to retrofit legacy systems with acceptance test suites so we can maintain them with less fear and more confidence.
Marc Andreessen famously said, “Software is eating the world.” Dr. Steve Willmott subsequently retorted, “APIs are eating software.” This is because API based architectures are enabling companies to get away from monolithic architectures and move to microservices. Innovative, disruptive companies like Netflix, Airbnb, Uber, Square, and Slack all build their infrastructure and technology using APIs.
In High-Performance Computing (HPC) uptime and performance are very important. HPC is an area of computing that often focuses on research and development, supporting teams with extremely complex problems they need to solve, and heavy computation mathematical problems, such as protein folding for vaccine development. To achieve this, HPC systems rely on high performance, the equipment is expensive, and the average customer has very high demands.
