1. Comparing a Few Common Gateways Nginx, a reverse proxy with a modular design, written in C OpenResty, a web development platform built around Nginx that can parse and execute Lua scripts Kong, an application on top of OpenResty, an API gateway with API management and request proxying, using PostgreSQL for storage APISIX, which replaces Kong’s PostgreSQL with Etcd and is built on Nginx’s core libraries APISIX’s advantage lies in the API management and extensibility it provides, so the gateway no longer merely forwards traffic to services but can be configured and customized.

1. Where Serverless Fits If cloud computing is meant to make resources flow like tap water — turn it on and use it, turn it off and it stops — then Serverless is one of the future directions of cloud computing. Compared with runtimes such as IaaS and Kubernetes, Serverless

1. Background 1.1 Problems with the Current Use of Jenkins The orchestration engine is unstable Jenkins is an orchestration engine written in Java, and it stops the world (STW) during a full GC. Under large-scale builds, STW can prevent Jenkins from handling new requests. Heavy builds stall Jenkins stores data in disk files; every pipeline and every build occupies a file directory, producing a huge number of files.

1. The Advantages of Multi-Cluster Tekton Builds Thanks to Kubernetes, Tekton already has good elasticity and can support large-scale builds. At the same time, developing Tasks mainly uses Yaml and Shell, which widens the range of scenarios Tekton can adapt to. The figure above is a sketch of Tekton across multiple clusters.

1. Basic Features of a CICD Platform A common CICD engine is not suitable to hand directly to the business side. The main reasons are the high learning cost for users, the lack of necessary authentication, and the difficulty of maintenance and upgrades. We usually build on top of a process engine, adapting it to the business to improve usability and encapsulating it for specific scenarios to reduce complexity.
