I recently came across a book which I got from LISA conference last November. It was written by Jake Sorofman who is VP, Product/Marketing at rPath. I thought it’s just another typical book from a vendor, therefore I didn’t read it until two weeks ago while sorting my bags. It’s not. After reading it, I found this 75 page booklet pretty easy to read and very insightful.
Here are 6 musts Jake discussed in his book:
Bothered by SLOW Web UI to manage vSphere? Want to manage ALL your VMware vCenters, AWS, Azure, Openstack, container behind a SINGLE pane of glass? Want to search, analyze, report, visualize VMs, hosts, networks, datastores, events as easily as Google the Web? Find out more about vSearch 3.0: the search engine for all your private and public clouds.
- Get your platforms under control
- Get your applications under control
- Version control everything
- Control changes through the lifecycle
- Update surgically
- Become metrics driven [Note: validated by Twitter admin team and others.]
I think the core of the 6 musts is the system model – how you describe your systems, including platforms and applications, with well designed meta data or/and scripts. You can then apply techniques like version control and become metrics driven.
By reading his book, I am more convinced that the future of system administration is automation. You cannot afford running cloud without system automation.
I googled the book title, and found you can get a free ebook or hardcopy after registration at rPath website.
