Notes de l'éditeur
- Why is this transformation important? Let’s take a look at the next few years before us… In 2020, 1 million new devices are expected to come online every hour. The connectivity between people and data is creating billions of new relationships that are driven not only by data but by algorithms that keep customers engaged and buying.* In 2020, the average age of a S&P 500 corporation is expected to be 12 years old. Compare that to the S&P 500 in 1960 when the average age was 60 years old.** By the year 2025, at least 60 percent of computing will be cloud-based, due to “everything-as-a-service” shifting fundamental changes in the IT industry.*** For digital transformation, mobility is the universal catalyst and cloud is the great enabler. How are you planning for digital transformation? Do you have the right people and the right technology in place to build your digital vision? How can you use technology to shape your future? *http://www.gartner.com/newsroom/id/3142917 **http://upstart.bizjournals.com/resources/author/2015/06/04/fortune-500-must-disrupt-or-die-writes-r-ray-wang.html?page=all ***http://www.emersonnetworkpower.com/en-US/Latest-Thinking/Data-Center-2025/Documents/002401_DataCenter2025Report_HR_INTERACTIVE.PDF
- Here’s what we hear from dev Want to be able to move fast Things to run smooth on their machine and production – dev / prod parity Don’t want to be blocked on IT / ops team
- IT - wants to minimize risk don’t really understand applications or what it takes to be a dev Unable to do both infrastructure stuff and handle the application operations
- There have been various computer-driven revolutions in the past: the widespread introduction of the personal computer (PC) was one, the invention of the graphical browser was another, and the Internet yet another. There have also been computer eras where one type of computer has dominated, having straightforward implications for whether the computers were shared or personal, and for whether they were specialized commodities or not (see diagram below). But the ways computers have altered our lives, all aspects of our lives, is more comprehensive than, at first blush, recollections of these technological revolutions or eras might suggest. Computers affect how we undertake the most prosaic of activities – from buying food to paying our bills – and they do so in ways we might not have imagined when the first personal computers arrived on our desks. They have also created wholly new experiences, for example, allowing us to inhabit virtual worlds with people from many different parts of the globe. In between these extremes, from the prosaic to the wholly new, computers have taken over from older technologies in ways that looked merely like substitution at first but which have ended up creating radical change. Computers have played a massive role in changing the way we live over the last couple of decades. They are no longer possessions of the privileged but are rapidly becoming inexpensive, everyday commodities. They have evolved from being isolated machines to globally interconnected devices. Not only has access to computers vastly increased, but the ways we interact with them and materials used for computer devices have changed too. All of this means that computers can now be interwoven with almost every aspect of our lives. As we move towards 2020, so the extent of these changes will increase. By 2020, it may not be possible to realize all of our goals, ambitions and aspirations without using a computer or computing in one way or another. This binding of computing to our daily activities will in turn affect our values, goals and aspirations.
- Traditional model - Empathize, land the case for change based on change in business context Take empathizing tone (don’t want to make this sound negative). We want them to realize that what customers have done may have worked in the past but they need to recognize the need for change as the business is changing rapidly. Most companies are running custom apps that are stitched together, they have purpose-built hardware to think about, and have specialized teams, and everything has been carefully customized (over many years in some cases!). Now as an enterprise, you did all this for all the right reasons, but you might consider that it might be holding our customers (and their business) back in many ways given that the business context has changed fundamentally. In this new age of apps, the old way of doing this is causing friction because IT isn’t moving as fast as business wants it to. This is manifested in developers not getting the speed and freedom they need to create the best end-user experiences. That leads to lost productivity on their side, which results in ‘Shadow IT’. In 2015, 42% of the technology budget resides outside IT; this will grow to 50% by 2020 (Gartner). So this is real. And we all know that while Shadow IT behaviors provide immediate gratification, it comes with risk. Slide 8: Cloud model (Mark) – Empathize, ask customers to be change agents, land cloud principles. Now let’s look at the cloud. Everyone knows that the cloud offers agility and innovation. It’s proving itself to be the way forward for the modern enterprise and we’ll talk more about that in a bit. But for some of our IT customers, the cloud might seem a little daunting. They might be asking, “Is this something I want to lead the charge on? How does it help my career?” The tension some of them experience is because you’re not sure if things are consistent with what you’re doing on-premises and it seems like it will be hard to manage. There’s also a tension between developers who want speed and freedom (represented by business demands), and the IT folks who have to worry about things like security and compliance. Bridge to our POV while bringing them along. Implore them to be change agents in their orgs. But make no mistake about it – the cloud is the natural way forward for the rapidly evolving enterprise. Let’s all embrace it. In this context, we’re already seeing some leading indicators around “bi-modal“ IT among you: 45% of CIOs have a second, fast, mode of service delivery that complements their rock solid operations” (Gartner Symposium, Oct 2014). So there’s already some great progress that a lot of you seem to be driving. This is do-able. And we want our customers to be change agents in driving cloud adoption in your orgs. Our POV We believe that cloud is a model/architecture, not a location. (Cloud-first principles as in the slide) Turns out that Microsoft has been on its own cloud-first journey for many years and we have fully operationalized cloud-first in our hyper-scale datacenters. We’d like to share some of that next to help customers shortcut their journey.
- Context, motivation and vision come from the top, but there are still barriers to overcome all the way down. Another example: in a recent company meeting, Satya said that improving our engineering systems is more important than adding new features. (Can we get the exact quote?)
