From its humble origins in the 1950s, Artificial Intelligence (or AI) has grown in scope and impact; capturing the imaginations of many from Hollywood to Wall Street. We already know how AI can help us park our cars or order online but is there any way that it can help software engineers improve the quality…

EKS vs GKE
by glenn •
Here I compare and contrast Kubernetes as it runs on both Amazon’s and Google’s respective clouds in terms of ease of provisioning, cost, and performance under load of a nine component system for a simple news feed application. I also share with you a secret that I learned about AWS during the research that went…

Revisiting Scala
by glenn •
Have you ever been involved in a microservice rewrite effort? Come with me as I take you through a Scala microservice coding adventure that was a complete rewrite of an existing Scala microservice. We shifted paradigms in the hope of making Scala more desirable. Was the new service a real improvement over the old one?…

Python Flask vs Node.js
by glenn •
Disillusioned with Java, many small startups are considering either Python or Node.js for their micro-services. This blog can help you decide which is right for you. I will explore what it is like to develop a rudimentary news feed micro-service written in version 3 of Python on Flask by comparing that experience with developing the…

Clouds Compared
by glenn •
We all know that, in the world of cloud computing, Amazon Web Services is the leader by far. Network intelligence group, Synergy Research, recently released a report revealing that cloud vendors Microsoft, IBM, and Google had increased their market share by 5% (combined). I thought that perhaps it was time to see if there really…

ElasticSearch vs Solr
by glenn •
It’s relatively easy to add advanced, scalable search capabilities to almost any application these days. All you have to do is sprinkle in a few calls to a popular open source search service in your code. That is what I did to the rudimentary news feed micro-service that I have implemented many times. In this…

Node.js vs DropWizard
by glenn •
I have been evaluating various Java based technologies by writing a news feed micro-service in those technologies and blogging about the Developer eXperience. In this blog, I will turn my attention to the first of many non-Java based technologies where I wrote yet another news feed micro-service implementation, this time in the Node.js programming language.…

DropWizard vs Ring
by glenn •
I have been blogging here a lot about the new kids on the JVM block, namely Clojure and Scala. I wanted to see how they compared against the more established Java frameworks. When version 1 of DropWizard was released, I decided that was the time to write another news feed micro-service implementation. This blog is…

MySql vs PostGreSql vs Docker
by glenn •
In my last blog, I compared two functionally identical micro-services, one written in Scala and the other in Clojure, in terms of performance under load in AWS. In this blog, I compare the performance of the Scala micro-service under load in AWS running with MySql, running with PostGreSql, and running both with and without Docker.…

Micro-Services: Scala vs Clojure
by glenn •
In my last blog, I compared Clojure to Scala when it came to coding micro-services. In this blog, I compare those same micro-services in terms of performance under load in AWS. Here are some answers to questions about the document below. In my next blog, I will share the outcome when comparing performance metrics for…
