Cloud computing's destiny: operating as a single global computer, enabled by serverless

By Joe McKendrick

"We are well down the road of executing our vision of making the world's cloud resources as easy to use as a single computer. When we do, we will finally realize the full revolutionary potential of the cloud. The ability to get what we need when we need it down to the millisecond with the click of a button."

That's the word from Priya Nagpurkar, director of hybrid cloud platform for IBM Research. In a recent interview with SVP and Director of IBM Research Dario Gil. Nagpurkar explained how IBM Research is pioneering a serverless computing architecture that will transform the cloud into the world's largest computer. Serverless computing will make this all possible opening access without the complications of backend provisioning and security management. 

There are data centers for the world's top public clouds in hundreds of locations that span nearly every continent. "However, this only paints a portion of the picture," says Gil. There are also a "massive number of private computing environments that exist in silos across the globe. The cloud has dramatically evolved over many years to what it is today, a massively distributed network of public and private data centers comprising zettabytes of computing power and data storage." For all the progress of what's happening on cloud, we have to "get to the point where we get the cloud to work as if it was a single infinitely powerful computer," says Nagpurkar. Right now, there are too many obstacles in the way, she adds. "Think about the simplicity of just working on your laptop. You have a common operating system tools you you're familiar with. And, most importantly, you're spending most of your time working on code. Developing on the cloud is far from that. You have to understand the nuances of all the cloud providers -- there's AWS, Azure, GCP, IBM, and private clouds. You have to provision cloud resources that might take a while to get online. And you have to worry about things like security, compliance, resiliency, scalability, and cost efficiency. It's just a lot of complexity."

Proprietary software stacks from different vendors "not only add to all this complexity but they stifle innovation," she says.  "Key software abstractions start with the operating system. Linux as the operating system for the data center era unleashed this proliferation of software, including virtualization technologies like containers. That ushered in the cloud era."
