Congress fights for additional Wi-Fi spectrum

A Congressional committee is weighing in on a spat between the FCC and parts of the automotive industry over a plan to appropriate a piece of wireless spectrum set aside for connected cars and instead designate it for Wi-Fi.The dispute centers on Dedicated Short Range Communications or DSRC, a point-to-point communication standard designated to let vehicles close to each other on roadways share information to improve safety. The go-to example is using it to warn a driver near-instantly if the car ahead suddenly slams on its brakes.[Get regularly scheduled insights by signing up for Network World newsletters.] DSR and its 75MHz of spectrum in the 5.9GHz band has been a relatively obscure technology until late last year when the FCC started considering that 45MHz of that spectrum should be made available for unlicensed wireless use such as Wi-FiTo read this article in full, please click here

Survey: Digital transformation can reveal network weaknesses

Digital transformation is a catch-all phrase that describes the process of using technology to modernize or even revolutionize how services are delivered to customers. Not only technology but also people and processes commonly undergo fundamental changes for the ultimate goal of significantly improving business performance.Such transformations have become so mainstream that IDC estimated that 40% of all technology spending now goes toward digital transformation projects, with enterprises spending in excess of $2 trillion on their efforts through 2019.To read this article in full, please click here

How to back up Kubernetes and Docker

Yes, your container infrastructure needs some type of backup.  Kubernetes and Docker will not magically build themselves after a disaster. As discussed in a separate article, you don’t need to back up the running state of each container, but you will need to back up the configuration used to run and manage your containers.Here’s a quick reminder of what you’ll need to back up.[Get regularly scheduled insights by signing up for Network World newsletters.] Configuration and desired-state information The Dockerfiles used to build your images and all versions of those files The images created from the Dockerfile and used to run each container Kubernetes etcd & other - K8s databases that info on cluster state Deployments - YAML files describing each deployment Persistent data created or changed by containers Persistent volumes Databases Dockerfiles Docker containers are run from images, and images are built from Dockerfiles. A proper Docker configuration would first use some kind of repository such as GitHub as a version-control system for all Dockerfiles. Do not create ad hoc containers using ad hoc images built from ad hoc Dockerfiles. All Dockerfiles should be stored in a repository that allows you to pull historical Continue reading

It’s the end for Windows Server 2008 support

This week's Patch Tuesday marked the end of the line for both Windows 7 and Windows Server 2008 (and 2008 R2). No more fixes will be issued for the two aged operating systems, unless you purchase a pricey extended service license.On the Windows 7 front, Microsoft has done a good job getting Windows 10 deployed through its aggressive (perhaps too aggressive) upgrade program. According to StatCounter, Windows 10 now accounts for 65% of the worldwide desktop Windows market share, and Windows 7 is down to 27%.

Google Cloud launches Archive cold storage service

Google Cloud announced the general availability of Archive, a long-term data retention service intended as an alternative to on-premises tape backup.Google pitches it as cold storage, meaning it is for data which is accessed less than once a year and has been stored for many years. Cold storage data is usually consigned to tape backup, which remains a surprisingly successful market despite repeated predictions of its demise.Of course, Google's competition has their own products. Amazon Web Services has Glacier, Microsoft has Cool Blob Storage, and IBM has Cloud Storage. Google also offers its own Coldline and Nearline cloud storage offerings; Coldline is designed for data a business expects to touch less than once a quarter, while Nearline is aimed at data that requires access less than once a month.To read this article in full, please click here

Enterprises spend more on cloud IaaS than on-premises data-center gear

Enterprise tech crossed a significant line as the decade ended. For the first time, enterprises spent more annually on cloud infrastructure services than on data-center hardware and software, according to Synergy Research Group.Synergy reports that total spending on cloud infrastructure services in 2019 will reach $97 billion, a 38% increase over the prior year. Ten years ago, that spending was near zero. Total spending on data center hardware and software, on the other hand, is expected to hit $93 billion in 2019, an increase of only 1% when compared to 2018.To read this article in full, please click here

How to deal with the impact of digital transformation on networks

Digital transformation has increased the importance of the network, particularly the edge, where customers, employees, cloud applications and IoT devices connect to the enterprise. The legacy static and non-differentiated network edge of years past is no longer sufficient for many reasons, so as companies embark on digital-transformation plans, their networks must evolve.Networking pros should be looking at, among other things, improving security and embracing software-defined networking (SDN) that supports propagating changes quickly across the network in order to accommodate the many challenges digital transformation creates.To read this article in full, please click here

BrandPost: How to Deliver Affordable and Optimized Application Access Worldwide with SASE

Global expansion is a common goal for many enterprises. In some verticals, like manufacturing, running production lines globally is an established practice. However, deploying international sales, service, and engineering teams is becoming the norm for many other sectors including high tech, finance, retail, and more.A global enterprise footprint creates a unique set of challenges that do not occur in regional businesses. Users in a remote office will need to securely access data-center applications, cloud applications, or both. Depending on the distance between the remote location and the application—and the sensitivity of the application to high latency, packet loss, and jitter—an expensive set of technologies and capabilities will be needed to optimize the user experience.To read this article in full, please click here

Wi-Fi 6 will slowly gather steam in 2020

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.The crux of the matter is that, while access points with 802.11ax’s Wi-Fi 6 branding will steadily move into enterprise deployments in, the broader Wi-Fi ecosystem will not be dominated by the new standard for several years, according to Farpoint Group principal Craig Mathias.To read this article in full, please click here

A new spin on interconnects for colocation data centers

It has been almost a year since I first wrote about Stateless, Inc., a startup devoted to bringing software-defined interconnects (SD-IX) to colocation data centers. At that time, the company was just announcing its plans to reinvent the means to connect workloads across data centers, hyperscale clouds and on-premises footprints using SD-IX. The intent was to give colo service providers a simpler way to quickly deploy network services for their tenants. Those plans have come to fruition and the company has announced the general availability (GA) of its Luxon SD-IX platform.To read this article in full, please click here

What to know before upgrading to Windows Server 2019

IT generally requires a good reason to disrupt a smooth working environment, which is why some hardware sits deployed for decades. Even though Windows Server 2016 is relatively young, there’s a decent argument to be made for upgrading a Server 2016 environment to Server 2019, the most recent release.There’s a longer span between Windows Server releases than the desktop version of the software because of slower migration habits on the server side, and this means bigger changes between releases. Windows Server 2016 was the first server OS built on the Windows 10 kernel, and some of the changes were rather rough. Windows Server 2019 is markedly faster, and it has a number of changes under the hood, from security to hybrid cloud integration. Here’s a rundown of what’s new and what are the most compelling arguments for upgrade.To read this article in full, please click here
