Google, an early convert to Puppet, uses its products to rapidly update the software running servers and employee PCs. So does music-streaming service Spotify. On servers or PCs, “it would have been impossible to grow and manage the Spotify infrastructure without a configuration management tool like Puppet,” says company engineer Johan Haals. GE Capital uses Chef to manage its servers and network switches, and chief engineer Justin Arbuckle says he can use it to distribute a new app across a network in a couple of hours. “In the past, it would have literally taken weeks and weeks,” he says.
"We have brought the storage into the cluster, and we have
commoditized it," says Ting, and this is why the US government,
financial services firms, healthcare companies, and educational
institutions are running a lot of proofs of concepts with the NX-3000
series of appliances.
About 25 per cent of the iron is going to Uncle Sam, which is in many
cases putting server clusters into vehicles to get image and signal
processing at command posts or into the field in Humvees, in some cases.
Virtual desktop infrastructure was the obvious early-use case for
Nutanix machines, and it is still driving a lot of deals, but Ting says
the company is seeing companies dump Microsoft workloads such as
Exchange Server and SQL Server on the boxes, and has just closed a deal
this month with a Global 2000-class company for 1,500 server nodes to
run an analytics workload."
"Google threw out the book on data centers and went back to basic heat
transfer and electrical theory, he explained, eliminating everything
not strictly necessary and coming up with a minimalist design."
"The first supercomputer capable of crunching through a thousand
trillion mathematical operations every second has been announced by
IBM. This is roughly equivalent to the combined processing power of a
2.4-kilometre-high pile of laptop computers."
