Simple Service for Managing Pools of 10s or 100s of Virtual Machines With Provisionr we want to solve the problem of cloud portability by hiding completely the API and only focusing on building a cluster that matches the same set of assumptions on all clouds, assumptions like: running a specific operating system (e.g. Ubuntu LTS), having the same set of pre-installed packages and binaries, sane dns settings (forward & reverse ip resolution - as needed for Hadoop), ntp settings, networking settings, ssh admin access, vpn access etc.

2. What?
• A service that can create and manage
pools of 10s or 100s of virtual machines
• A pool should match the same set of
assumptions on all clouds (os, dns,
packages, networking, ssh, vpn etc.)

3. Why?
• To create clusters with 50+ nodes for
Hadoop with pre-installed binaries
• ... and use tools like Cloudera Manager or
Ambari for configuration (leverage API)
• Why? Environment normalisation. Template
caching (auto-ami). Hidden behind an API.
Persistence. Traceability. Easy to restart.
