As edge computing evolves, the cloud’s role changes

The notion of edge computing typically conjures an image of a device in a factory someplace, providing rudimentary computing and data collection to support a piece of manufacturing equipment. Perhaps it keeps the factory temperature and humidity optimized for the manufacturing process.

Those who deal with edge computing these days understand that what was considered “edge” just a few years ago has morphed into something a bit more involved. Here are the emerging edge computing architecture patterns that I’m seeing:

The new edge hierarchy. No longer are edge devices connected directly to some centralized system, such as one residing in

Using OPA to safeguard Kubernetes

As more and more organizations move containerized applications into production, Kubernetes has become the de facto approach for managing those applications in private, public and hybrid cloud settings. In fact, at least 84% of organizations already use containers in production, and 78% leverage Kubernetes to deploy them, according to the Cloud Native Computing Foundation.

Part of the power and allure of Kubernetes is that, unlike most modern APIs, the Kubernetes API is intent-based, meaning that people using it only need to think about what they want Kubernetes to do — specifying the “desired state” of the Kubernetes object — not

What is quantum computing? Solutions to impossible problems

There’s no lack of hype in the computer industry, although even I have to admit that sometimes the technology does catch up to the promises. Machine learning is a good example. Machine learning has been hyped since the 1950s, and has finally become generally useful in the last decade.

Quantum computing was proposed in the 1980s, but still isn’t practical, although that hasn’t dampened the hype. There are experimental quantum computers at a small number of research labs, and a few commercial quantum computers and quantum simulators produced by IBM and others, but even the commercial quantum computers still have

Some observations on cloud computing observability

The term and the concept of observability aren’t new at all. Observability first appeared in the world of engineering and control theory. Although the definition depends on whom you’re asking, some common patterns and understandings are emerging. Mostly it’s a new buzzword by the AIops providers and some thought leaders in the cloudops space (meaning me). 

At its essence, observability is the measure of how well internal system states can be inferred from knowledge of all external data and states. It’s a bit different than monitoring which is something you do (a verb); observability is an attribute of a system

Amazon Braket: Get started with quantum computing

While IBM, Microsoft, and Google have made major commitments and investments in quantum computing, Amazon has, until recently, been fairly quiet about the field. That changed with the introduction of Amazon Braket.

Amazon still isn’t trying to build its own quantum computers, but with Braket it is making other companies’ quantum computers available to cloud users via AWS. Braket currently supports three quantum computing services, from D-Wave, IonQ, and Rigetti.

Higher ed needs a course in cloud computing

Four-year colleges may face up to a 20 percent reduction in fall enrollment, according to SimpsonScarborough, a higher education research and marketing company. Its findings are based on surveys of more than 2,000 college-bound high school seniors and current college students. 

According to the Chronicle of Higher Education, nine percent of institutions plan to operate only online during the fall semester. The remainder will take a hybrid approach, with some classes offered online, while other classes will operate both online and in-person. 

Some of the realities that colleges and universities now face include:

  • A large percentage of students who
