Harvard Business Publishing learns some lessons about work in the cloud

When Ken Griffin, the director of IT operations for Harvard Business Publishing, warned his staff, 12 months from now, those servers are being switched off, his message was crystal cleartheres no going back, learn the cloud or step aside.

Top management at Harvard Business Publishing, a nonprofit subsidiary of Harvard University that publishes management learning materials, decided in 2012 to go all-in on the cloud. We dont want to replace hardware anymore, Griffin said.

The company is now two years into a three-year plan to move all of its operations, consisting of more than 70 applications used by about 650 employees and contributors, to the cloud. Griffin shared some of the lessons he and his team learned on the journey at the Interop New York conference this week.

Moving to the cloud is more complicated than a simple lift-and-shift approach of copying software and data over to the hosted service, Griffin said. Organizations should be open to change, he said. The most efficient way to do something in the cloud may involve a radically different approach than doing it in-house.

Some of the migrations were fairly easy, such as moving mail services to Office365. Griffin was surprised how many cloud services employees were already using before the official decision to move operations. Employees were using Jive, Jira, Dropbox and a variety of commercial consumer and enterprise services.

The base infrastructure, built on Amazon Web Services (AWS), required more planning, though. Initially, Harvard Business Publishing had planned to replicate AWS infrastructure services in the on-premises systems and not make any architectural changes. This approach quickly proved to be inefficient.

Today, there are no Web servers in Harvard Business Publishings cloud operations. Content is served directly from Amazons Simple Storage Service (S3), and delivery can be auto-scaled as demand waxes and wanes.

With AWS architecture is key, Griffin said. Poor cloud-system design means that you will be in a world of pain, Griffin warned.

AWS can provide organizations a fair bit of help to transition to the cloud. Griffin advised getting a professional support subscription and then letting AWS know how much your organization plans to spend. Once Griffin indicated that Harvard Business Publishing could spend up to US$50,000 a year running operations on AWS, Amazon made sure its questions were answered.

While the technology may need rethinking, Griffin found the biggest challenge was getting existing IT staff to move to a cloud mindset.
