Server teams ensure reliability ,availability and serviceability for servers such that these SAAS/PAAS platform run on the servers with absolutely no downtime or 99.9999 up time.
This talk provides an overview of
What does such an architecture look like ?
What are key engineering challenges in building server platforms?
What does the H/W look like in those servers?
What are open sources around it ?
