c* summit 2013: stepping through the lifecycle of a service offering with cassandra by chris mceniry...
DESCRIPTION
It's a fine line to walk for incorporating new technologies in an organization with 15+ years of legacy software. In this presentation, we'll look at the lifecycle and adoption of Cassandra from a skunkworks project to a full fledged service in a legacy organization.TRANSCRIPT

Ops Concerns

* How do we keep it from blowing up? * How do we keep it cared for for its lifetime? * How do we keep from being a bottleneck? * How do we keep from being woken up at 4AM? * How do we keep up with “gimme!gimme!gimme?"
Ops Concerns

* Marketing features vs. real features − What is on the outside of the box? − What does actually work?
* C* is young − our understanding of it is young
* Does it solve our problem adequately? − POCPOCPOC − We analyzed lots of in-memory data grids
-‐ Some had marketing feature problems -‐ Some were too young -‐ Some were too expensive -‐ None of them addressed partitioning very well -‐ If for nothing else, the cold startup time is a killer
* Adoption − Can we implement C* in our organization?
Dev Concerns

* Dev – you're not running production. * Ops – you’re not writing the code. * Work with someone
− Who sees the same problem − Is excited about the technology − Agrees on the direc0on − Does not have an inherent conflict of interest
Can’t do it by yourself

* Not a problem that can be solved by slapping a cache in front of existing technology
* Need distributed storage * Global distribution helps with both latency and disaster recovery
− Data replica0on and synchroniza0on are built-‐in − Par00on events are handled out of the box
* Continuous delivery is part of the C* philosophy
Why Does C* Fit Here?
