The diversity of devices from Cloud to the Edge has proliferated the number of languages, tools and technologies, each of which bring specialized advantages to the context. For instance, increased capability of client-side computing brought in front-end frameworks such as single-page/progressive web applications and the trend to increasingly opt for Microservices has led to emergence of lighter application frameworks. Similarly, better container management tools on the server-side make it easier to build cloud-agnostic solutions and ensure easier management of containers. Along with this, No-SQL databases increasingly contribute to the server-side architecture transformation.

More recent areas of expansion are the low-code/no-code platforms, and AI being used as part of the Dev-Ops cycle.

Due to the sheer number of technologies under the umbrella of Software Engineering, we are covering the tools that are more popular or have gained more traction in 2021. Many tools that emerged during 2020 and covered by the previous version of Tech Beacon are still around.
