Cloud computing: Battle of the clouds

From the Economist Battle of the clouds:

The idea is that computing will increasingly be delivered as a service, over the internet, from vast warehouses of shared machines. Documents, e-mails and other data will be stored online, or “in the cloud”, making them accessible from any PC or mobile device. Many things work this way already, from e-mail and photo albums to calendars and shared documents.

This represents a big shift. If you store more and more things online, and access more and more software through an ordinary web browser, it suddenly matters much less what sort of computer you have, and what kind of software it is running.

By switching to cloud-based e-mail, accounting and customer-tracking systems, firms can reduce complexity and maintenance costs, because everything runs inside a web browser. Providers of cloud services, meanwhile, can benefit from economies of scale. Why should every company or university set up and maintain its own mail server, when Google or Microsoft can do it more efficiently? Companies are already happy to rely on utilities to provide electrical power, after all. Cloud computing will do the same for computing power.

The ability to summon computing capacity from the cloud when needed will also give the software industry a shot in the arm. During the dotcom boom, the first thing a start-up had to do was raise the money to buy a room full of servers. If a website experienced a sudden surge in popularity, more servers were needed to meet demand. Today a capacity can be rented as needed, allowing cloud services to scale up smoothly. This lowers barriers to entry and promotes innovation and competition.

From the Economist Clash of the clouds:

Windows 7 is not just a sizeable step for Microsoft. It is also likely to mark the end of one era in information technology and the start of another. Much of computing will no longer be done on personal computers in homes and offices, but in the “cloud”: huge data centres housing vast storage systems and hundreds of thousands of servers, the powerful machines that dish up data over the internet. Web-based e-mail, social networking and online games are all examples of what are increasingly called cloud services, and are accessible through browsers, smart-phones or other “client” devices.

The rise of cloud computing is not just shifting Microsoft’s centre of gravity. It is changing the nature of competition within the computer industry. Technological developments have hitherto pushed computing power away from central hubs: first from mainframes to minicomputers, and then to PCs. Now a combination of ever cheaper and more powerful processors, and ever faster and more ubiquitous networks, is pushing power back to the centre in some respects, and even further away in others. The cloud’s data centres are, in effect, outsize public mainframes. At the same time, the PC is being pushed aside by a host of smaller, often wireless devices, such as smart-phones, netbooks (small laptops) and, perhaps soon, tablets (touch-screen computers the size of books).

Apple is also secretive about the way it conducts its internal R&D. Mr Jobs clearly calls most of the shots. But insiders say that there is a system of teams that pitch projects to him.
