Celery worker is a simple, flexible, and reliable distributed system to process vast amounts of messages while providing operations with the tools required to maintain such a system. In this tutorial, we will learn how to implement Celery with Flask and Redis. Before we deep dive into the tutorial, let’s have a brief overview of Celery workers.

OpenMetrics and OpenTelemetry are popular standards for instrumenting cloud-native applications. Both projects are part of the Cloud Native Computing Foundation (CNCF) and aim to simplify how we generate, collect and monitor services in a modern cloud-native distributed application environment. Let's have a look at how both the standards are aiming to help solve the observability conundrum.

GraphQL is a query language and server-side runtime for APIs developed by Facebook in 2012. In this guide, we will implement an Angular Apollo GraphQL client with the help of a sample To-Do app. Before we demonstrate how to implement the Angular GraphQL client, let’s have a brief overview of the Angular framework and GraphQL.

Ruby on Rails is a popular MVC framework for creating web applications. It is necessary to monitor your Ruby applications for performance issues. In today’s cloud-native and microservices-based architecture, it is difficult for engineering teams to troubleshoot performance issues. Tracing your application can give the much needed context required to troubleshoot performance issues.

OpenTelemetry can be used to trace Rust applications for performance issues and bugs. OpenTelemetry is an open-source project under the Cloud Native Computing Foundation (CNCF) that aims to standardize the generation and collection of telemetry data. Telemetry data includes logs, metrics, and traces. Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency.

OpenTelemetry can be used to instrument your Elixir applications to generate telemetry data. The telemetry data can then be visualized using an observability tool to monitor your Elixir application performance. In this tutorial, we will use OpenTelemetry Elixir libraries to instrument an Elixir application and then visualize it using SigNoz. Somewhere during the lifetime of an application, it's inevitable that it will have some performance issues.

This is our 12th monthly product newsletter, and every month our team has shipped code to make SigNoz better for our users. Our latest release is special! It is not only packed with much-awaited user-requested features, but it is also the first time our team met in person to ship a release together. Yes, after 12 months of seeing each other on Zoom, we finally got a chance to see each other in person during our week-long workation.
