How to pick an off-site data-backup method

Everyone agrees that backups should be sent off site, but not everyone agrees on how that should be accomplished. The decision about which method to use will affect your recovery-time objective (RTO), recovery-point objective (RPO), risk level, and cost – so it’s rather important.To read this article in full, please click here(Insider Story)

The Importance of Container Visibility

Containers are unlike any other compute infrastructure. Prior to containers, compute infrastructure was composed of a set of brittle technologies that often took weeks to deploy. Containers made the automation of workload deployment mainstream, and brought workload deployment down to minutes, if not seconds.

Now, to be perfectly clear, containers themselves aren’t some sort of magical automation sauce that changed everything. Containers are something of a totem for IT operations automation, for a few different reasons.

Unlike the Virtual Machines (VMs) that preceded them, containers don’t require a full operating system for every workload. A single operating system can host hundreds or even thousands of containers, moving the necessary per-workload RAM requirement from several gigabytes to a few dozen megabytes. Similarly, containerized workloads share certain basic functions – libraries, for instance – from the host operating system, which can make maintaining key aspects of the container operating environment easier. When you update the underlying host, you update all the containers running on it.

Unlike VMs, however, containers are feature poor. For example, they have no resiliency: traditional vMotion-like workload migration doesn’t exist, and we’re only just now – several years after containers went mainstream – starting to get decent persistent Continue reading

On the ‘net: ATM

Asynchronous Transfer Mode, or ATM, was widely seen as a compromise technology that would provide the best circuit and packet switching in a single technology. Data would be input into the network in the form of either packets or circuits. The data would then be broken up into fixed sized cells, which would then be switched based on a fixed label-based header. This would allow hardware to switch the cells in a way that is like circuit switching, while retaining many of the advantages of a circuit switched network. In fact, ATM allowed for both circuit- and packet-switched paths to be both be used in the same network. @ECI’s LighTALK

IDG Contributor Network: Enterprise systems to monetize and bill for new IoT services

Enterprises adopt IoT solutions for two primary reasons. First, they want to lower their companies’ operating and capital costs. These types of IoT solutions including factory automation, remote asset monitoring, fleet management, and smart metering help enterprises improve their bottom lines by focusing on all sorts of cost reduction.Second, enterprises want to add IoT to the products they sell to their customers. This allows enterprises to bundle new connectivity-based services with their core products, thereby increasing revenue and differentiating their offerings. Examples of these types of IoT solutions include in-vehicle infotainment, connected welding equipment, connected commercial-grade power tools, and many more.To read this article in full, please click here

Open Source Containers in 2019

Open source containers are moving in a direction that many of us never anticipated. Long recognized as providing an effective way to package applications with all of their required components, some are also tackling one of the most challenging areas in the compute world today -- high performance computing or "HPC". And while containers can bring a new level of efficiency to the world of HPC, they're also presenting new ways of working for enterprise IT organizations that are running HPC-like jobs.How containers work Containers offer many advantages to organizations seeking to distribute applications. By incorporating an application's many dependencies (libraries, etc.) into self-sustainable images, they avoid a lot of installation problems. The differences in OS distributions have no impact, so separate versions of applications don't have to be prepared and maintained, thus making developers' work considerably easier.To read this article in full, please click here

Space data backbone gets U.S. approval

Soon we may have a space-based optical backbone capable of transferring data 1.5 times faster than Earth-based terrestrial fiber, now that the Federal Communications Commission (FCC) has given LeoSat the go-ahead to start its build-out.Moving “large quantities of data quickly and securely around the world, is fast outpacing the infrastructure in place to carry it,” says LeoSat in a press release announcing its FCC market-access grant last month. Upcoming LeoSat, will be a “a backbone in space for global business,” the company says.To read this article in full, please click here
