Achieving Concurren­cy On A Massive Scale

Achieving Concurren­cy On A Massive Scale

Tuesday, January 21, 2014

Where do you turn when the performance requirements of your application exceed what your 8­CPU Opteron server or homegrown Linux cluster can provide? What if the communication bandwidth of your cloud service is insufficient for your interprocessor communication needs? Your neighborhood BitCoin miner may already have the solution! The parallel processing technologies once reserved for government research labs are now within the reach of small companies. This seminar with review the history of multiprocessing and parallel processing and describe how modern computer hardware, languages, and frameworks can be utilized to achieve concurrency on a massive scale.

Building and Deploying 12 Factor Apps in Scala and Java

April 18, 2017

The twelve-factor app is a modern methodology for building software-as-a-service apps:

• Use declarative formats for setup automation, to minimise time and cost for new developers joining the project.

• Have a clean contract with the underlying operating system, offering maximum portability between execution environments.

• Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration.

• Minimise divergence between development and production, enabling continuous deployment for maximum agility.

• And can scale up without significant changes to tooling, architecture, or development practices.

We will build a RESTful web service in Java and deploy the app to CloudFoundry. We will go over how to build a cloud manifest, how to keep our database credentials and application configuration outside of our code by using user-provided services and go over what it takes to build a 12 Factor application in the cloud. This presentation will be heavy on code and light on slides!
