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…

Taming the Single Writer Principle: Mule vs Camel
by glenn • • 0 Comments
In the following article, you will find my write up of a weekend project exploring two implementations of a shard aware proxy that follows the content based router Enterprise Integration Pattern in order to enforce the single writer principle. One implementation uses the open source project Mule and the other integrates with Apache Camel. Here…

Ten things I learned while writing a Model Driven Software Development system for Google Closure
by glenn •
If you are considering the development of a MDSD system, then avoid making some costly mistakes by learning these ten lessons that I learned when I wrote a MDSD system that generates web 2.0 apps based on Google Closure and XMPP. If you can keep it simple, keep it useful, provide an editor, provide importers, generate clean code, automate the entire build process, and decouple both GUI and data store, then you’ll have a really cool tool.
