NGINX Unit is a new, lightweight, open source application server built to meet the demands of today’s dynamic and distributed applications. Deploy configuration changes with no service disruptions. Run code in multiple languages. Build the foundation of your service mesh.
In this session we will cover the technical challenges and reasons why we created Unit:
- Modern applications are changing all the time, and they require software that allows fast reconfiguration.
- Every complex application has multiple software stacks in place. It is always a mix of languages and technologies. Inconsistency in technology interaction can be fatal to the application.
- Inter-service communication is a topic that is becoming more interesting today, and service meshes are one of the available solution approaches.
In Unit, we addressed these challenges, and kept the software light and quick, in spirit of the rest of NGINX products:
- It’s open source under Apache 2.0 license.
- Unit runs PHP, Python, Perl, Ruby, Go apps.
- It runs various versions of the same language on the same server.
- Unit reconfigures in real time, and it’s done via a simple REST API.
- A reconfiguration does not create a reload workflow. Changes are done in-memory, instantly, as frequently as you want.
We will show the details on the implementation, and display a technical demo on how to use Unit with a variety of dynamic applications.
