Background
Apache Traffic Control is a Content Delivery Network (CDN) control plane for large scale content distribution.

Traffic Control currently requires Apache Traffic Server as the underlying cache. Help us expand the scope by integrating with the very popular Varnish Cache.

There are multiple aspects to this project:

• Configuration Generation: Write software to build Varnish configuration files (VCL). This code will be implemented in our Traffic Ops and cache client side utilities, both written in Go.

• Health Monitoring: Implement monitoring of the Varnish cache health and performance. This code will run both in the Traffic Monitor component and within Varnish. Traffic Monitor is written in Go and Varnish is written in C.

• Testing: Adding automated tests for new code

Skills:

• Proficiency in Go is required
• A basic knowledge of HTTP and caching is preferred, but not required for this project.

Apache APISIX is a dynamic, real-time, high-performance API gateway.

It provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

Background: Elasticsearch is a widespread search engine based on Apache Lucene. It allows users to index, store, and search for data via a REST API. Data going through APISIX are good candidates to be transferred to Elasticsearch for later analysis.

Task: The intern should evaluate different possible designs, analyze their pros and cons, and implement at least one in agreement with the mentor.

In particular, the intern should investigate ES requirements for writing data (amount of data, frequency, etc.) prior to any development.

Project title:

Multiple programming languages client SDK support with OpenAPI generator.

Apache APISIX is a dynamic, real-time, high-performance API gateway.

It provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

Background:

OpenAPI Generator allows the generation of API client libraries (SDK generation), server stubs, documentation, and configuration automatically given an OpenAPI Spec.

We can use it to provide Apache APISIX Admin and Control API SDKs in multiple programming languages. In the future, we may potentially integrate Java SDK into Spring framework and the starter of Spring boot or even make integration with ASP .Net

Task:

Generate a multilingual SDK through the definition files of the OpenAPI specification and use the OpenAPI Generator tool to generate client SDKs for Admin and Control APIs.

Difficulty: Normal
Project size: ~350 hours.
