It has been a few years now since I moved into the role of Software Engineering Management. While there may be various reasons for one to move to this role, it is a change that comes with very little training and no guidebook. In this blog, I will go over a few areas that I felt are areas to keep an eye on when in this role (a lot of it is relevant to non-manager lead roles too).

Take2 — Setting up k8s Cluster with k3s on Raspberry Pi 3 & Pi 4
Back to a teach-myself-something type of project, with setting up K8s Cluster on Raspberry Pi devices. I had a couple of older Raspberry Pi 3s and a recently purchased Pi 4 available for this. My old Pi3 devices had Docker Swarm (yes that one) from a couple of years back. This time around I want to get k8s on the 3 Pi devices.
The steps are fairly simple but it can be a bit of work. You should find blogs out there with decent enough directions. So here goes me adding to that library of blogs to make it easier for the next person trying to set this up.
This is an upgrade from my previous similar blog installing Docker Swarm on a two node Pi-3 cluster https://54.210.73.122/running-docker-swarm-raspberry-pi-3/
Get started with AWS SAM
I am going to point you to a few resources to help you standup a hello world serverless app using AWS Lambda using AWS Serverless Application Model (SAM).
Setting up your own VPN server for personal use on AWS
I have used (still use) a commercial VPN service (for those few occasions I am outside and need some extra security). But I have always wanted to standup my own VPN server to have a bit more confidence that my activity logs are not being watched (worse sold or hacked) by a 3rd party VPN provider. Punted this for a long time, but found the perfect opportunity to do that today while waiting for some car repairs at an auto service center.
Legacy Modernization – Eyes Open Please !
My random thoughts on two things to keep in mind before you get into a legacy modernization effort. One is to “know what you are getting into” and the other is “have patience”.
Metrics with Spring Boot, Prometheus and Grafana
Capturing metrics from your system is critical to understanding its internal behavior and to tune its performance. Without this you are operating in the blind. In this post we will go through how you can gather metrics from a Spring Boot application using Prometheus, Grafana and Micrometer.

Running Istio on Minikube to implement traffic routing
There are multiple strategies you could use to introduce new service versions to an existing product. In this article I will go over how you can implement Canary deployments using Istio in a k82 cluster. The same approach can be used to implement Blue/Green deployments too.
Mono’s Journey from monolith to microservices
Once upon a time there lived a monolith application named Mono (creative ah!).

Digital Transformation
You probably have heard leadership talk about Digital Transformation in meetings, town halls and blogs. Industry pundits seem to talk/write about it; often using it to rank which companies are competing at the topmost level in their industry. Often though there isĀ confusion among the rank and file employees about this whole “Digital” thing. Is it the latest buzzword that executives are in love with (probably true to some extent)? Is there anything behind it or just a lot of hot air? Who are all those high priced management consultants that show up to tell us about Digital Transformation, without explaining what it is?
Container Native Serverless platform – fnProject
On a mission to run as many open source serverless/FaaS frameworks. Looking for ease of use on a local development machine (no cloud). Starting with fnproject first.
