Then came March, and the first wave of the Covid-19 pandemic hit U.S. shores. In the course of one weekend, Dell pivoted to having more than 90% of its workforce working from home.

Essential things to know about container networking

Article | March 8, 2020

Containers have emerged over the past several years to provide an efficient method of storing and delivering applications reliably across different computing environments. By containerizing an application platform and its dependencies, differences in OS distributions and underlying infrastructures are abstracted away. Networking has emerged as a critical element within the container ecosystem, providing connectivity between containers running on the same host as well as on different hosts, says Michael Letourneau, an IT architect at Liberty Mutual Insurance. "Putting an application into a container automatically drives the need for network connectivity for that container," says Letourneau, whose primary focus is on building and operating Liberty Mutual's container platform.

How 5G and edge computing can enhance virtual reality

Article | April 8, 2020

For some time now, 5G has been associated with the promise of new digital applications and services that come with a hyper-connected life. We have seen that this new technology, which provides “perfect” connectivity, creates new value for both us as individuals and to industries and enterprises. The current global pandemic is drastically impacting our daily lives, and as a result, the relevance of such digital applications and services is accelerating. For example, we suddenly see an increased need for communication services, tools for remote collaboration, and fast and reliable access to data – whether it’s from the office, the home or somewhere in between. Augmented and virtual reality (AR and VR) are two technology concepts providing significant benefits in this new digital reality. These technologies open new ways of working in areas such as manufacturing, gaming, media, automotive and healthcare, allowing for both increased productivity and completely new user experiences. In the Ericsson ConsumerLab merged reality report, 7 out of 10 early adopters expect VR and AR to change everyday life fundamentally.
