Part 1 | Part 2
Until recently, all custom BOSH CPIs were forks of the BOSH project. They were hard to maintain and had to be implemented in Ruby. In August 2014, the BOSH team introduced the new external CPI mechanism that has removed these constraints. The second part of our blog series on adding BOSH support to custom clouds will be dedicated to external BOSH CPIs, how they are used, and what it takes to build one.
