MORE NETWORKS PUBLIC OR PRIVATE OR WHAT?

•  2 NIC •  Private network (does not have to be addressable) •  Public network (API/ management network, addressable)

•  Make interface decisions early on. •  VLAN considerations

•  How many VMs? How many users?


IN THE END NETWORK AND LAYOUT PLANNING


2 DBA CENTOS INSTALL

•  Why CentOS? •  The docs say you can do a minimal install… don’t. •  Versioning is worth a second look (dnsmasq, Python) •  Storage decisions: cinder-volume (block storage), glance (object storage)

•  Ephemeral vs permanent •  Understand your storage scenarios early on


OPENSTACK DECODER RING UNDERSTANDING THE VARIOUS PROJECTS


INSTALLING & CONFIGURE POST-INFRASTRUCTURE

•  Read the manual, but don’t take a manual approach •  Know the OpenStack release schedule •  CLI vs Horizon Configuration •  Consider automatic deployment solutions


PACKSTACK NIRVANA YOU’LL BARELY EVEN REMEMBER INSTALLING

•  Automating your deployment •  Answers file •  Puppet

•  Options for all-in-one or multi-node •  Easily add new nodes

YET ANOTHER PROJECT? WILL SAVANNA BE OUR HEROINE?

•  Open source hadoop cluster management tool backed by: •  RedHat •  Mirantis •  Hortonworks •  Others….

•  Allows for one click cluster deployment. •  Neutron not support (yet)
