Communication service providers must transform support systems to realize 5G’s true potential

5G-tower

Until now, each transition to the next generation of wireless networks, most recently 3G to 4G, has been incremental and relatively seamless. But the jump from 4G networks to 5G is expected to be monumental and fundamentally disruptive. 5G is more than just a faster, lower-latency version of 4G; it represents the first generation wireless […]

CoreDNS: The DNS for cloud-native computing

DNS

I have a t-shirt which reads, from top to bottom: “It’s not DNS. There’s no way it’s DNS. It was DNS!” As every sysadmin knows, all too many network problems boil down to a Domain Name System (DNS) blunder. That’s already annoying, but when you have to deal with a DNS headache with fast-moving containers […]

The Calico cloud

You know what’s one of the real pains of cloud and container based computing? Networking. Workloads on a cloud come and go faster than you can read this story. Connecting those workloads, especially when they become even more ephemeral containers, is not easy. That’s where the open-source Software Defined Network (SDN) Calico comes in. SDN […]

Time to scale network virtualization

The telecommunications industry is a mature sector that is being revitalized and challenged by its customers and new competition. Subscribers seeking digital life styles and enterprise customers seeking to be agile digital businesses all depend on the communication networks more than ever before. Carriers have a tremendous opportunity to service these highly desirable customer segments; […]

Will AI destroy IT jobs?

broken-glass

One thing that’s become clear as artificial intelligence (AI), machine learning, neural networks and other “smart” technologies invade the workplace is that enterprises will be more reliant than ever on IT professionals to ensure that networks, applications and data are constantly ready and available. After all, replacing a low-skilled call center rep with a chatbot […]

How Venmo and other payment sharing apps change culture

Venmo-screenshot

If you ask a group of 20-somethings how to split a dinner tab, you’ll get a totally different answer than you would from their boomer parents. This became readily evident in a graduate class I teach on cross-cultural communications made up mostly of international students between 21-26 years old. Just three years ago when I […]

La W de wearable

Ya sea un reloj inteligente o una pulsera fitness, nuestras muñecas llevan hoy en día muchos de los wearables más populares, y este campo está en constante expansión, con nuevas formas de conectar sensores y datos a nuestra vida diaria. En general, la “ropa inteligente” comprende casi cualquier artículo que podamos llevar puesto y que […]

When your IT users are on Mars

Mars-surface

Both Elon Musk’s SpaceX program and Mars One are racing to colonize Mars. Meanwhile, the U.S. government wants to use the moon to “build the foundation we need to send Americans to Mars and beyond,” as Vice President Mike Pence recently explained. Who will be first to establish a permanent human presence on the moon, […]

SD-WAN: Building a network of networks

The stage is now set for a significant transformation in networking due to our ever-increasing expectation to connect anywhere and at any time. The move of applications — in particular more data hungry and time sensitive applications like video and voice — to cloud environments is driving this transformation. The combination of these factors means […]

The unintended effects of mobile apps

aerial-view-of-neighborhood

We wonder every day what we would do without certain mobile apps. Two that come up often are Google Maps and Waze (now owned by Google). Every day, drivers put their faith in these apps to provide the most direct, traffic-minimized route to their final destination. In many cases the routing is counterintuitive, but for […]
