Lessons Learned From a Cloud Migration

It’s hard to go anywhere today and not be inundated with the cloud. I see billboards on highway 101 between San Jose and San Francisco, there are cloud signs in airports, and it seems every TV show has some kind of cloud commercial embedded in it. This has put tremendous pressure on IT leaders to […]

Hot Air Hype or a New Route to The Hybrid Cloud?

Claiming to have a unique ‘hybrid cloud’ delivery strategy, HP has now released its Helion hybrid cloud portfolio for cloud builders, service providers, ISVs and enterprise customers.

Speeding up Network Provisioning

You probably know the problem already. The business is opening up a new office; has acquired a new company or wants to move a group of people from Place A to Place B. They have finally got around to letting IT know that it will happen – and they want you to wave your magic […]

Operational Challenges Continue To Plague Legacy WANs

This site, like many others, has focused on the need to evolve the WAN. Much of the value proposition for the shift to a hybrid WAN is to improve application performance, which is often poor over WAN.
