After a long selection process and a myriad of rumors on who would take the helm at Microsoft, Satya Nadella, former executive VP of Microsoft's Cloud and Enterprise group, is stepping up to replace Steve Ballmer. Nadella is a Microsoft veteran having joined the company 22 years ago and moving forward he'll be responsible for driving the tech icon that is as successful as it is troubled today.

On the consumer side, Microsoft has long been at the receiving end of criticism for the slow evolution of its Windows and Office products. Nonetheless, those continue to lead in the traditional PC market and contribute handsomely to the software giant's bottom line. Entertainment (Xbox) and cloud divisions are among the most successful future-looking endeavors for the company, while mobile computing (Windows/Mobile) and web (Bing) have been elusive targets where the company has often been too late to the party.

Microsoft has been on a late shift to a "devices and services" company as touted by former CEO Steve Ballmer, yet the continued pressure for radical change is what pushed the company to look elsewhere for a new leader. Satya Nadella will be only the third CEO in the company's history. Along with the new CEO announcement, Bill Gates is effectively stepping down as chairman and will become a technology advisor to the company. John Thompson, who was heading Microsoft's CEO search committee, is taking Gates' former position as Chairman of the Board.

Indian-born Nadella, 46, studied electrical engineering when he attended Mangalore University. Later on, he moved to the US to earn a master's degree in computer science from the University of Wisconsin and a master's degree in business administration from the University of Chicago. He was working for Sun Microsystems before he joined Microsoft in 1992. Nadella was part of the team that built the first Windows NT operating system as he was familiar with UNIX and 32-bit operating systems.

His tenure at Microsoft continued as senior VP of R&D for the Online Services Divisions, vice president of the Microsoft Business Division and most recently as president of Microsoft's Server and Tools Business where he led a transformation and major shift to cloud infrastructure and services.

On his first day at the job, Satya Nadella has written an open email to Microsoft employees, which we've reproduced below:

Today is a very humbling day for me. It reminds me of my very first day at Microsoft, 22 years ago. Like you, I had a choice about where to come to work. I came here because I believed Microsoft was the best company in the world. I saw then how clearly we empower people to do magical things with our creations and ultimately make the world a better place. I knew there was no better company to join if I wanted to make a difference. This is the very same inspiration that continues to drive me today.

It is an incredible honor for me to lead and serve this great company of ours. Steve and Bill have taken it from an idea to one of the greatest and most universally admired companies in the world. I've been fortunate to work closely with both Bill and Steve in my different roles at Microsoft, and as I step in as CEO, I've asked Bill to devote additional time to the company, focused on technology and products. I'm also looking forward to working with John Thompson as our new Chairman of the Board.

While we have seen great success, we are hungry to do more. Our industry does not respect tradition --- it only respects innovation. This is a critical time for the industry and for Microsoft. Make no mistake, we are headed for greater places --- as technology evolves and we evolve with and ahead of it. Our job is to ensure that Microsoft thrives in a mobile and cloud-first world.

As we start a new phase of our journey together, I wanted to share some background on myself and what inspires and motivates me.

Who am I?

I am 46. I've been married for 22 years and we have 3 kids. And like anyone else, a lot of what I do and how I think has been shaped by my family and my overall life experiences. Many who know me say I am also defined by my curiosity and thirst for learning. I buy more books than I can finish. I sign up for more online courses than I can complete. I fundamentally believe that if you are not learning new things, you stop doing great and useful things. So family, curiosity and hunger for knowledge all define me.

Why am I here?

I am here for the same reason I think most people join Microsoft --- to change the world through technology that empowers people to do amazing things. I know it can sound hyperbolic --- and yet it's true. We have done it, we're doing it today, and we are the team that will do it again.

I believe over the next decade computing will become even more ubiquitous and intelligence will become ambient. The coevolution of software and new hardware form factors will intermediate and digitize --- many of the things we do and experience in business, life and our world. This will be made possible by an ever-growing network of connected devices, incredible computing capacity from the cloud, insights from big data, and intelligence from machine learning.

This is a software-powered world.

It will better connect us to our friends and families and help us see, express, and share our world in ways never before possible. It will enable businesses to engage customers in more meaningful ways.

I am here because we have unparalleled capability to make an impact.

Why are we here?

In our early history, our mission was about the PC on every desk and home, a goal we have mostly achieved in the developed world. Today we're focused on a broader range of devices. While the deal is not yet complete, we will welcome to our family Nokia devices and services and the new mobile capabilities they bring us.

As we look forward, we must zero in on what Microsoft can uniquely contribute to the world. The opportunity ahead will require us to reimagine a lot of what we have done in the past for a mobile and cloud-first world, and do new things.

We are the only ones who can harness the power of software and deliver it through devices and services that truly empower every individual and every organization. We are the only company with history and continued focus in building platforms and ecosystems that create broad opportunity.

Qi Lu captured it well in a recent meeting when he said that Microsoft uniquely empowers people to "do more." This doesn't mean that we need to do more things, but that the work we do empowers the world to do more of what they care about --- get stuff done, have fun, communicate and accomplish great things. This is the core of who we are, and driving this core value in all that we do --- be it the cloud or device experiences --- is why we are here.

What do we do next?

To paraphrase a quote from Oscar Wilde --- we need to believe in the impossible and remove the improbable.

This starts with clarity of purpose and sense of mission that will lead us to imagine the impossible and deliver it. We need to prioritize innovation that is centered on our core value of empowering users and organizations to "do more." We have picked a set of high-value activities as part of our One Microsoft strategy. And with every service and device launch going forward we need to bring more innovation to bear around these scenarios.

Next, every one of us needs to do our best work, lead and help drive cultural change. We sometimes underestimate what we each can do to make things happen and overestimate what others need to do to move us forward. We must change this.

Finally, I truly believe that each of us must find meaning in our work. The best work happens when you know that it's not just work, but something that will improve other people's lives. This is the opportunity that drives each of us at this company.

Many companies aspire to change the world. But very few have all the elements required: talent, resources, and perseverance. Microsoft has proven that it has all three in abundance. And as the new CEO, I can't ask for a better foundation.

Let's build on this foundation together.
