Hadoop is often viewed as needing racks of dedicated boxes -despite the fact that in sheer number terms, the majority of Hadoop clusters ever created have been brought up on public cloud infrastructures -particularly Amazon`s. Yet the rest of datacenter computing is moving towards virtualization -be it in-cloud startups or in-enterprise IT departments. Some organizations are standing up private clouds: a rack or two of servers with an API for VM creation. Hadoop can live there -it just needs to integrate better. At the same time, OpenStack is emerging as the de-facto standard open source cloud platform for private use, and is available publicly from a number of cloud infrastructure service providers. This talk looks at what we`ve done -and are doing- to integrate Hadoop with OpenStack. This is taking it beyond Hadoop`s current support for Amazon`s infrastructure, making a combined Hadoop + OpenStack cluster something to consider in-house -and in-cloud. This work is being done in collaboration with members of the OpenStack community, showing how cloud and big data projects can not only co-exist, we can co-develop our platforms.
