How to Create a Network Proxy Using Stream Processor Pipy
In this article we are going to introduce Pipy, an open-source cloud-native network stream processor. After describing its modular design, we will see how to rapidly build a high-performance network proxy to serve our specific needs. Pipy has been battle-tested and is already in use by multiple commercial clients.

Why Change Intelligence is Necessary to Effectively Troubleshoot Modern Applications
Change Intelligence is often a missing component in incident management. Successfully correlating monitoring and observability data to arrive allows engineers to arrive at the root cause more rapidly. Telemetry provides the building blocks that enable change intelligence to identify and map the root cause, based on changes in the system and their broader impact.

Lightweight External Business Rules
Complex enterprise applications usually come with varying business logic. Such conditions and subsequent system actions, known as rules, are ever varying and demand involvement of domain specific knowledge more than technology and programming. The rules must reside outside the codebase, authored by people with core domain expertise with minimal tech knowledge.

Implementing Pipeline Microservicilities with Tekton
Microservicilities is a list of cross-cutting concerns that a service must implement apart from the business logic. These concerns include invocation, elasticity and resiliency, among others. This article describes how a service mesh such as Istio may be used to implement these concerns.
