An example of an event-triggered process might be to […]

Example Big Data dev cluster topology

Below is an example dev cluster topology for a Big Data development cluster as I’ve actually used for some customers.  It’s composed of 6 Amazon Web Service (AWS) servers, each with a particular purpose.  We have been able to perform full lambda using this topology along with Teiid (for data abstraction) on terabytes of data.

I’ve been mind-numbingly fortunate to enjoy an exciting career and have been able to pick my customers, employers, and problems I’d like to solve.  I left my career as an engineering geologist in the late 90s moving to modeling and simulation, robotics, finance, healthcare, government, and currently internet technologies.  Today I focus on strategy and tactics for big data and machine learning architecture, practice building, process, and the development of intellectual property.

I hope you find value in the templates, processes, and tools I have built and provided here.  If you’d like to discuss any of these please feel free to contact me through the information at the link below.

I’ve been fortunate to help write some of the early architectural standards on big data and to build a portfolio of intellectual property for myself and my employers.  Here are a few highlights.
