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…

Micro-Services: Clojure vs Scala
by glenn •
In a previous post, I compared Scala and Clojure when it came to processing big data. In this post, I am comparing Scala and Clojure in the world of micro-services. Earlier, I had written a rudimentary news feed service in Clojure. Recently, I re-implemented the same news feed service in Scala. Given the same task,…

Distributed Computing and Functional Programming
by glenn •
In a previous blog on some big data open source projects covered at OSCON 2014, I reviewed three distributed computing functional programming technologies by using them to write a simple aggregation report. In that blog, I mentioned reproducing the news feed performance map reduce job from a Clojure news feed service that I test ran…

Functional Programming and Big Data for the Impatient Learn about the future of Functional Programming and Big Data by reading this evaluation of three relevant open source technologies; PigPen, Cascalog, and Apache Spark. A small report is written, that reports on the per minute count of post actions from a two hour test run of…

Building a Scalable News Feed Web Service in Clojure
by glenn • • 0 Comments
The company where I currently work pays for each engineer to go to the conference of their choice once a year. One of my co-workers decided to go to Java One. When he came back, he shared with us the theme for that year which was Functional Programming. I decided that it was time to…
