Title: VP of development for the data platform group in Microsoft’s Server and Tools Business
Previous Company And Role: He spent the past three years at SAP overseeing business analytics and HANA, SAP's in-memory database, a type of super-fast database that can store data and analytics on it at the same time.

Title: VP of product management for consumer PCs
Previous Company And Role: He spent most of the past three years as a VP in Amazon's Kindle unit. Before that he worked at Microsoft for more than 18 years, and was corporate VP of Windows Platform Strategy when he left.
Game Changing Skills: He's got a diverse background: He was the first product manager on the Windows NT marketing team, and he also headed up Microsoft's security tech unit. Nash was also in charge of Windows during the Vista debacle, so he's used to operating under pressure. And with the consumer PC market tanking, he'll face no shortage of it at HP.

Previous Company And Role: He came to EMC from Huawei, where he's spent the previous four years in R&D roles. He's also held CTO roles at Nortel, Broadcom and Enterasys.
Game Changing Skills: EMC told us his experience in tech innovation and incubation made him an attractive hire. EMC spends about 11% of its annual revenue on internal R&D and about the same amount on acquiring tech, so it needed a CTO who's good at identifying promising tech.

"This is not some little project. This is the culmination of literally 50 years of my focus on artificial intelligence," he told Forbes' Robert Hof in an April interview. "I’ve always had in mind working on the ultimate challenge, which I believe is being able to really model and understand natural language and using that to do practical things."

Title: VP and chief architect of AMD's microprocessor cores

Title: VP of engineering
Previous Company And Role: He was VP of Engineering at Red Hat and led development of cloud computing software.

Title: EVP Corporate Services and Chief Information Officer

Tom Lane, Salesforce
Joined: May 2013
Title: None at this time

Game Changing Skills: He's an expert in PostgresSQL, an open source database. His hiring is said to be part of Salesforce's ongoing effort to lessen its dependence on Oracle databases.
"Tom’s move is part of a significant pattern of investment by large corporations in the future of Postgres," Selena Deckelmann, a Postgres contributor, said last month in a blog post.
Lisa Jackson, Apple
Joined: May 2013
Title: VP of environmental initiatives
Previous Company And Role: She spent the past four years as head of the U.S. Environmental Protection Agency.
Game Changing Skills: Apple doesn't have the best reputation for making environmentally friendly products. It'll be Jackson's job to scrub Apple's image, and she'll also be driving Apple's efforts to use more renewable energy in its data centers. Apple CEO Tim Cook announced her hiring at the D11 conference last week.
Lang Wang, IBM
Joined: 2012
Title: Strategy & Transformation Consultant, IBM Global Business Services
Previous Company And Role: He joined IBM last August after graduating from Princeton with a degree in East Asian Studies. He has studied the impact of social media in China and has written papers on how people use it in that country.
Game Changing Skills: He doesn't have a tech background, but that's precisely why IBM hired him. He'll bring a completely new perspective to IBM's business, using the knowledge he's gathered about social media and applying it to help the company solve business challenges.
Mike Bell, Intel
Joined: May 2013
Title: Vice President and GM of New Devices
Previous Company And Role: He's been with Intel since 2010, and prior to that spent 3 years at Palm and 16 years at Apple.
Game Changing Skills: Brian Krzanich tapped Bell to lead Intel's new mobile devices unit. While he's not a new employee, that fact that Intel is placing a great deal of emphasis on mobility right now makes him a key hire for an important role.
He's got lots of experience leading big product groups: One of his former colleagues at Apple, in a recommendation on LinkedIn, describes Bell as having a "phenomenal touch for managing a large technical organization".
Radhesh Balakrishnan, Red Hat
Joined: December 2012
Title: GM of Red Hat's virtualization business unit
Previous Company And Role: Balakrishnan joined Microsoft in 1999 and held a variety of cloud computing related positions during his time there. He helped put together Microsoft's $250 million cloud partnership with Hewlett-Packard in 2010.
Game Changing Skills: He's good at partnerships, and it'll be his job to get Red Hat more involved with OpenStack, a set of open source cloud computing tools that many enterprise vendors are building businesses around.
