5G in 2020: Still just a private party

To hear the major mobile carriers talk about it, 5G is here. They’ve deployed it, it works, and it’s ready to start changing the world just about right away, with ultra-fast connectivity, low latency and a dramatically improved ability to handle huge numbers of different connections at once.Eventually, that will all be true – but, according to experts in the field, it isn’t yet, and most of it won’t take place within the coming calendar year. The 3GPP standards that will underpin all new-radio 5G technology are still not yet finalized, although that is expected to happen in early 2020, which means the much-touted 5G deployments in the U.S. are based partially on pre-standard technology.To read this article in full, please click here

Data centers in 2020: Automation, cheaper memory

It’s that time of year again when those of us in the press make our annual prognostications for the coming year. Some things we saw coming; the rise of the cloud and the advance of SSD. Others, like the return of many cloud migrations to on-premises or the roaring comeback of AMD, went right by us. We do our best but occasionally there are surprises.So with that, let’s take a peek into the always cloudy (no pun intended) crystal ball and make 10 data-center-oriented predictions.IoT spawns data-center growth in urban areas This isn’t a hard prediction to make since it’s already happening. For the longest time, data centers were placed in the middle of nowhere near renewable energy (usually hydro), but need is going to force more expansion in major metro areas. IoT will be one driver but so will the increasing use of data center providers like Equinix and DRT as interconnection providers.To read this article in full, please click here

What’s big in IT tech for the coming year

As the year winds down it's a good time to take a quick look ahead at what the new year might bring in order to be better prepared to make smart decisions.Nowhere is that more important than in IT, where the choices enterprise leaders make will have implications not only for themselves and their customers, but also for the overall economy, which depends more and more on corporate networks delivering business-critical services reliably.Here, we take a look how some of the most critical technologies will fare in 2020.What’s hot for Cisco in 2020 IDG Cisco is expected to continue its cloud, security, and SD-WANefforts in 2020, but there are hurdles to overcome. “Overall, I think it’s clear that Cisco needs to get into the cloud in a more effective way," said analyst Tom Nolle, president of CIMI Corp. "I think their recent reorg shows they understand that. Cloud Interconnect is a sideshow. What’s needed is infrastructure-independent development and deployment, which would relegate Cloud Interconnect to nothing but a network gateway.” (Read more.)To read this article in full, please click here

Counting down the days using bash

With some pretty important holidays right around the corner, you might need to be reminded how much longer you have to prepare.Fortunately, you can get a lot of help from the date command. In this post, we’ll look at ways that date and bash scripts can tell you how many days there are between today and some event that you’re anticipating.[Get regularly scheduled insights by signing up for Network World newsletters.] First a couple hints at how this is going to work. The date command’s %j option is going to show you today’s date as a number between 1 and 366. January 1st, as you’d expect, will be displayed as 1 and December 31st will be 365 or 366 depending on whether it’s leap year. Go ahead and try it. You should see something like this:To read this article in full, please click here

What’s hot for Cisco in 2020

As the industry gets ready to gear up for 2020 things have been a  little disquieting in networking land.That’s because some key players – Arista and Juniper in particular – have been reporting business slowdowns as new deals have been smaller than expected and cloud providers haven’t been as free-spending as in the past.[Get regularly scheduled insights by signing up for Network World newsletters.] Worldwide IT spending has been on the slow side, Gartner said in October that worldwide IT spending is projected to total $3.7 trillion in 2019, an increase of 0.4% from 2018, the lowest growth forecast so far in 2019. The good news: global IT spending is expected to rebound in 2020 with forecast growth of 3.7%, primarily due to enterprise software spending, Gartner stated.To read this article in full, please click here

Google Cloud bare-metal initiative targets migrating legacy apps from on-prem

In the cloud-services market, bare metal offerings have lagged behind virtualized ones, mostly because the use of the cloud for things like elastic apps and developer environments are better suited to instances with a native operating system.The term “bare metal” simply means no software of any kind, not even a hypervisor. Customers provide their own operating environments, and the provider offers nothing more than CPUs, memory, and storage. Up to now, IBM has led the charge with bare-metal services because SoftLayer, the major data-center provider it acquired in 2014, was heavily involved in that business.To read this article in full, please click here

SD-WAN Squares and Perplexing Planes

The latest arcane polygon is out in the SD-WAN space. Normally, my fortune telling skills don’t involve geometry. I like to talk to real people about their concerns and their successes. Yes, I know that the gardening people do that too. It’s just that no one really bothers to read their reports and instead makes all their decisions based on boring wall art.

Speaking of which, I’m going to summarize that particular piece of art here. Note this isn’t the same for copyright reasons but close enough for you to get the point:

So, if you can’t tell by the colors here, the big news is that Cisco has slipped out of the top Good part of the polygon and is now in the bottom Bad part (denoted by the red) and is in danger of going out of business and being the laughing stock of the networking community. Well, no, not so much that last part. But their implementation has slipped into the lower part of the quadrant where first-stage startups and cash-strapped companies live and wish they could build something.

Cisco released a report rebutting those claims and it talks about how Viptela is a huge part of Continue reading

Update: Using pyATS in Network Automation

A month ago I described how Paddy Kelly used pyATS to get VRF data from a Cisco router to create per-VRF connectivity graphs.

Recently he also wrote a short article describing how to get started with pyATS and Ansible. Thank you, Paddy!

Heavy Networking 492: Using Streaming Telemetry To Inform And Enhance Automation (Sponsored)

Streaming telemetry is an essential element in a network automation framework. On today's Heavy Networking, sponsor Juniper Networks joins the podcast to discuss how telemetry differs from traditional monitoring such as SNMP, how telemetry informs and enhances automation, and how to consume telemetry to make it actionable without overwhelming network operators (or your collectors). Our guest is Javier Antich from Juniper's Automation Software team.

Why Open Source Matters More for Bare Metal

IFX2019. Developers tend to pay less attention to the underlying bare metal infrastructure supporting their open stack deployments. This is understandable amid the explosion of available open source tools and platforms on the cloud. But as the dust settles and organizations seek more ways to improve application performance, bare metal servers and devices are emerging as a key differentiator among DevOps teams looking for any way to improve application performance, and ultimately, the user experience. The issue, for many developer teams, is thus how to have control over the entire stack which, again, covers the bare metal infrastructure as well. Packet has built its business around provisioning infrastructure for on-premises and the cloud, software that boosts server and overall ecosystem performance is critical as well — and for a number of reasons, open source alternatives play an obvious key role in what Packet does. While Packet has contributed the open source community largely by providing servers and infrastructure for development purposes to projects such as the CNCF and CI/CD platform Nathan Goulding, chief architect for Continue reading
