GraphQL adoption patterns

Wed, 15 Feb 2023 02:31:56 +0000

GraphQL is a query language and runtime designed by Facebook in 2012 and publicly released in 2015. It has gained widespread popularity in recent years, with many companies adopting it as their primary API architecture. It is a query language and runtime that allows clients to request data from servers using a unified interface. One of the reasons for its popularity is its flexibility, which allows developers to implement it in different ways depending on their use cases. In this blog post, we will explore four common GraphQL adoption patterns: client only, backend for frontend, the monolith, and multiple overlapping graphs.

GitOps and ArgoCD

Fri, 09 Dec 2022 03:31:56 +0000

What is GitOps?

GitOps is a modern approach to software delivery that streamlines the process of deploying and managing applications by leveraging the power of Git and automation tools. At the heart of GitOps is the concept of “declarative infrastructure,” which means that the desired state of the infrastructure is defined in a declarative way, and the system automatically ensures that the actual state matches the desired state.
