Microservice is now the architecture of choice for many developers when crafting cloud-native applications. A microservices application is a collection of loosely coupled services that communicate with each other, enhancing collaboration, maintainability, scalability, and deployment. There are several options for enabling this communication between microservices. REST is the most popular among developers, sometimes used synonymously with APIs. However, gRPC can be a better alternative to REST.

In this article, we will explore the main metrics of a GitHub repository and why it is important to monitor them. We will learn how to get GitHub data in a convenient format, process, then visualize it for further analysis. Finally, we will analyze the main advantages of using data monitoring tools such as Hosted Graphite and Grafana by MetricFire.

Welcome to the 7th edition of Open Source Matters: our regular publication about the latest happenings in open source! Let’s dive into the news.

You can accomplish so by simply downloading Linux and making the necessary adjustments. In essence, we can distinguish them as different Linux versions.

When you think of who uses feature flags, your mind most likely goes to developers. In general, feature flags are closely associated with software engineering. But Site Reliability Engineers, too, can benefit from feature flags. SREs may not be the ones to create feature flags, but they should work closely with developers to ensure that the applications their teams support include feature flags.

2021 was quite a year. Some things changed, and some things very much stayed the same. The world of cyber security was not immune to this zeitgeist, with some aspects of the threat landscape persisting and some rapidly changing and evolving.

We know the old adage: All data is security-relevant. But at what cost? Many organizations are still trying to get their arms around existing data flows and tooling to say nothing of new apps and data sources coming into play as we continue to migrate to the cloud. Working to get a complete picture of their security environments, many CISOs are forced to make painful decisions between staying within budget and getting complete security event visibility.
