Observability requires efficient tools and configurations for log shipping, metrics collection, performance monitoring, event management, tracing, and visualization. Applications with good observability receives quality feedback, iterates and matures faster.
In the DevOps landscape, there are many observability tools. These tools usually requires comprehensive configuration to integrate with your software solution.
In the open-source ecosystem there are well-known technologies such as Java-based ELK (Elasticsearch, Logstash and Kibana) stack and the PLG stack (Prometheus, Loki and Grafana). Each Cloud vendor also have their native tools such as CloudWatch, CloudTrail, Azure Monitor, etc.

- From Ingress to CRD: why my solution needs Istio Gateways on Kubernetes platforms - In my Korthweb project I was researching for the best ingress mechanism for HTTP and TCP workload, both of which need to be secured. I started with Kubernetes Ingress but eventually decided to go with Istio Gateway. This blog post is about the justification. In this essay, I will make… ...

- From Microservice to Service Mesh - We all know what microservice is now but how does service mesh assist with microservice development. Microservice Microservice as an architecture was firstly conceptualized in this article by Martin Fowler in 2014. It covers the pros (strong module boundaries, independent deployment, technology diversity) and cons (dealing with distributed system, eventual… ... Read moreFrom Microservice to Service Mesh
- Istio Lab – Ingress and Egress - Istio is a popular open-source service mesh implementation using Envoy proxy. One of the benefit of using Istio is the ingress and egress it brings to native Kubernetes platform. This article is a hands-on guide to test Istio ingress and egress gateways on Minikube. It was tested on my MacBook.… ... Read moreIstio Lab – Ingress and Egress
- Logging and Monitoring in Kubernetes with PLG stack - We've checked out the the actors in PLG stack (Promtail, Loki, Node Exporter, Prometheus, Grafana) and whipped up a quick pipeline on MacOS. Now I'm going a little further to implement the same PLG stack (Prometheus Loki and Grafana) in a Kubernetes cluster. This setup is for demo only, therefore… ...

- Intro to PLG stack -Prometheus, Loki and Grafana - Last month we discussed log shipping with EFK. This week I spent sometime checking out its alternative Loki. Having been exposed to the ELK stack extensively, I am also interested in exploring the counterparts in this new stack, such as Prometheus, Loki and Grafana. So I need to address the… ...
