Twenty Indians  working for global giants like Microsoft, Oracle, Hewlett Packard, Google and Motorola, who are influencing how the global technology business will shape up in the next few years, are part of a list of "20 Indians who are making a difference."

Most of them are from the Indian Institutes of Technology.

The list of 20 Indian technology greats who are influencing the technology business globally is part of CyberMedia's flagship technology journal Dataquest - a special issue being unveiled to coincide with the Nasscom annual conference starting in Mumbai Feb 14.

The list is dominated by multiple Indians who are part of the global search giant, Google (Amit Singhal, Google fellow; Nikesh Arora, chief business officer and Sundar Pichai, Senior VP, Chrome) and Hewlett Packard (Prith Banerjee, Senior VP Research and director, HP Labs and Vyomesh Joshi, Executive VP, printing & imaging).

Also in the list are those charged with building the technology roadmaps for the world's top software companies - Vishal Sikka, Chief Technologist of SAP; Thomas Kurian, in charge of the product roadmap of Oracle (the company with broadest range of software products) and Satya Nadella, the low-profile president of Microsoft's servers and tools business.

The list also includes the US government's first federal CTO Aneesh Chopra (who stepped down Feb. 8), McKinsey consultant Dilip Wagle, and blogger Om Malik of GigaOM whose words are followed on Twitter by some of these big executives themselves.

Cisco's CTO Padmasree Warrior is the only woman on the list. The two CEOs on the list are Sanjay K Jha, chairman & CEO, Motorola Mobility, and Shantanu Narayen, CEO, Adobe. (Warrior will be addressing the Nasscom India Leadership Forum in Mumbai.)

With over a dozen in this list being in their 30s and 40s, Dataquest editors expect them to move to CEO roles in the coming few years to play an even more significant role in shaping the technology.

(In alphabetic order)

Those Indians who have contributed in the past but are no more active do not feature in the list, because their actions cannot influence the current and future trends. The only two veterans who still feature in the list--Vyomesh Joshi and Vinod Khosla--are there because they are still influencing how the technology business shapes up.

Not surprisingly, most of those on the list are engineers, with a majority from the IITs at Delhi, Madras, Kharagpur, Kanpur, Roorkee. There are people from other colleges too: IT BHU, MS University, Osmania, and Manipal.

The sole non-engineer in the list-Om Malik--comes from St Stephens,Delhi. He is the odd one out. A journalist-turned-blogger, he is actually one of the few in the list who have actually worked in India for some time. IT Trainer NIIT also lists Malik amongst its alumni.

IBM, which employs more people in India than in the U.S., does not have a single top executive who is Indian and is the only significant tech company that is missing from this list.
