How to back up Kubernetes and Docker
» ‎ Network World

Tags: [edit]
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 versions of that Dockerfile should there be a problem with the current build.

Locking and unlocking accounts on Linux systems
» ‎ Network World

Tags: [edit]

If you are administering a Linux system, there will likely be times that you need to lock an account. Maybe someone is changing positions and their continued need for the account is under question; maybe there’s reason to believe that access to the account has been compromised. In any event, knowing how to lock an account and how to unlock it should it be needed again is something you need to be able to do.

One important thing to keep in mind is that there are multiple ways to lock an account, and they don't all have the same effect. If the account user is accessing an account using public/private keys instead of a password, some commands you might use to block access to an account will not be effective.

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
» ‎ Network World

Tags: [edit]

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.

Serverless computing: Ready or not?
» ‎ Network World

Tags: [edit]

Until a few years ago, physical servers were a bedrock technology, the beating digital heart of every data center. Then the cloud materialized. Today, as organizations continue to shovel an ever-growing number of services toward cloud providers, on-premises servers seem to be on the verge of becoming an endangered species.

Serverless computing is doing its share to accelerate the demise of on-premises servers. The concept of turning to a cloud provider to dynamically manage the allocation of machine resources and bill users only for the actual amount of resources consumed by applications is gaining increasing acceptance. A late 2019 survey conducted by technical media and training firm O'Reilly found that four out of 10 enterprises, spanning a wide range of locations and industries, have already adopted serverless technologies.

Instant, secure ‘teleportation’ of data in the works
» ‎ Network World

Tags: [edit]

Sending information instantly between two computer chips using quantum teleportation has been accomplished reliably for the first time, according to scientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU). Data was exchanged without any electrical or physical connection – a transmission method that may influence the next generation of ultra-secure data networks.

Teleportation involves the moving of information instantaneously and securely. In the “Star Trek” series, fictional people move immediately from one place to another via teleportation. In the University of Bristol experiment, data is passed instantly via a single quantum state across two chips using light particles, or photons. Importantly, each of the two chips knows the characteristics of the other, because they’re entangled through quantum physics, meaning they therefore share a single physics-based state.

BrandPost: SD-WAN Enables Large-Scale Enterprise Deployments Including Mobile & IoT
» ‎ Network World

Tags: [edit]

As global enterprises continue to adopt and deploy SD-WAN as a key enabler of cloud and digital transformation initiatives, they must also consider the importance of infrastructure scalability to accommodate the dynamic nature of connecting users to business applications and services regardless of where they are physically located. This is driving an increased focus on ease-of-use, automation, and orchestration, which industry analyst firm Futuriom cites as one of the top features of SD-WAN functionality.

Why is this becoming increasingly important? Many large-scale global enterprises have multiple divisions, business units or subsidiaries that may each require a dedicated SD-WAN fabric to comply with company financial policies, geography, business jurisdiction or regulatory requirements or simply to create independent administrative domains. Each fabric can be individually orchestrated and managed yet still provides centralized network-wide visibility and control, including aggregated observability of the entire network.

How to deal with the impact of digital transformation on networks
» ‎ Network World

Tags: [edit]

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.

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.

Sources in Asian memory chipmakers are projecting that NAND flash contract prices will rise by 40% in 2020 due to product ramps and increased demand, according to the Taiwanese publication DigiTimes.

The article, now locked behind a subscription wall, cited sources at Taiwanese memory makers. However, the biggest makers of NAND flash are not Taiwanese, like Samsung, Toshiba, and Micron. This would impact memory cards, USB flash drives, and solid-state drives. It noted the contract price of SSDs had been falling for a few years and only started to rise after production issues reduced NAND output in the second quarter of 2019.

Generating numeric sequences with the Linux seq command
» ‎ Network World

Tags: [edit]
One of the easiest ways to generate a list of numbers in Linux is to use the seq (sequence) command. In its simplest form, seq will take a single number and then list all the numbers from 1 to that number. For example:
```
$ seq 5
1
2
3
4
5
```
Unless directed otherwise, seq always starts with 1. You can start a sequence with a different number by inserting it before the final number.
```
$ seq 3 5
3
4
5
```
Specifying an increment
You can also specify an increment. Say you want to list multiples of 3. Specify your starting point (first 3 in this example), increment (second 3) and end point (18).

Researchers aim for transistors that compute and store in one component
» ‎ Network World

Tags: [edit]

Researchers at Purdue University have made progress towards an elusive goal: building a transistor that can both process and store information. In the future, a single on-chip component could integrate the processing functions of transistors with the storage capabilities of ferroelectric RAM, potentially creating a process-memory combo that enables faster computing and is just atoms thick.

The ability to cram more functions onto a chip, allowing for greater speed and power without increasing the footprint, is a core goal of electronics design. To get where they are today, engineers at Purdue had to overcome incompatibilities between transistors – the switching and amplification mechanisms used in almost all electronics – and ferroelectric RAM. Ferroelectric RAM is higher-performing memory technology; the material introduces non-volatility, which means it retains information when power is lost, unlike traditional dielectric-layer-constructed DRAM.

What to know before upgrading to Windows Server 2019
» ‎ Network World

Tags: [edit]

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.

BrandPost: Rethink Data Centers with Data @ the Center
» ‎ Network World

Tags: [edit]

Mention the data center and, to most, images of machine rooms filled to the brim with equipment and the sounds of IT whirring away are what come to mind. For decades, businesses have equipped data centers with silo upon silo of servers, applications, networking, and storage in their insatiable quest to deliver business insight to line-of-business (LOB) leaders, their management, and the C-suite. Even the name data center was given based on the theory that most business-critical data would be found there, centralized, and ready for the business to derive competitive insights to bolster its marketplace advantage.

However, the data center, as we have traditionally known it, often falls short in its mission to deliver business advantage. The premise is sound, but the execution has been limited by the technology at hand. For many, the problem is the data center is not a centralized repository of data; rather it is a centralized collection of applications, each with its dedicated compute and storage resources (physical or virtual, it doesn’t matter), surrounded by edge computing facilities driven by LOB concerns.

7 ways to remember Linux commands
» ‎ Network World

Tags: [edit]

Some Linux commands are very easy to remember. The names may have only a couple letters and they often relate directly to what you want to do – like cd for changing directories or pwd for displaying the present working directory. Others can be very difficult to remember, especially if what you want to do relies on using a series of options.

So, let’s look at some commands and tricks that can help you remember commands that do just what you need them to do and that make issuing those commands so much easier.
Use aliases
The best way to nail down a complicated command is to turn it into an alias. Just take a command that works for you and assign it an easy name. In fact, there is nothing wrong with using the name of the command itself as the alias as long as this doesn’t interfere with other ways you might want to use that command. For example, grep and egrep are often aliased to include using color to highlight your search term.

The concept of using passive optical LANs in enterprise campuses has been around for years, but hasn’t taken off because most businesses consider all-fiber networks to be overkill for their needs. I’ve followed this market for the better part of two decades, and now I believe we’re on the cusp of seeing POL go mainstream, starting in certain verticals.

The primary driver of change from copper to optical is that the demands on the network have evolved. Every company now considers its network to be business critical where just a few years ago, it was considered best effort in nature. Downtime or a congested network meant inconvenienced users, but today they mean the business is likely losing big money.

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:

Data centers in 2020: Automation, cheaper memory
» ‎ Network World

Tags: [edit]

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.

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

Tags: [edit]

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.

Seagate doubles HDD performance with multi-actuator technology
» ‎ Network World

Tags: [edit]

Seagate has taken the wraps off its Exos 2X14 enterprise hard drive. It's the first to integrate Seagate's MACH.2 multi-actuator technology, which is a method of turning one hard disk into two and doubling performance.

The technology is pretty straightforward. Say you have four platters in a disk drive. The actuator controls the drive heads and moves them all in unison over all four platters. Seagate's multi-actuator makes two independent actuators out of one, so in a six-platter drive, the two actuators cover three platters each.

Researchers experiment with glass-based storage that doesn't require electronics cooling
» ‎ Network World

Tags: [edit]

Hard drives aren’t going to be capacious enough for future data archiving and retrieval requirements, scientists believe, as applications such as artificial intelligence, wide-scale Internet of Things connectivity, and virtual and augmented reality take hold. Glass could be the answer.

Encoding in glass would have advantages over hard drives and other mediums, experts suggest. Holding capacity is greater, and the slivers of quartz being experimented with don’t need cooling or dehumidifying environments.

Microsoft Research, working in the UK along with the University of Southampton, announced that it has been able to store an entire movie on a quartz, glass-based storage medium. The team stored and retrieved a full-length Superman film on a small slab of the special material that measures about 3 inches square and less than a tenth of an inch thick.

The VPN is dying, long live zero trust
» ‎ Network World

Tags: [edit]

The venerable VPN, which has for decades provided remote workers with a secure tunnel into the enterprise network, is facing extinction as enterprises migrate to a more agile, granular security framework called zero trust, which is better adapted to today’s world of digital business.

VPNs are part of a security strategy based on the notion of a network perimeter; trusted employees are on the inside and untrusted employees are on the outside. But that model no longer works in a modern business environment where mobile employees access the network from a variety of inside or outside locations, and where corporate assets reside not behind the walls of an enterprise data center, but in multi-cloud environments.

Verizon, Amazon team to offer 5G edge cloud computing via AWS Wavelength
» ‎ Network World

Tags: [edit]

Amazon and Verizon will offer the ability to run AWS-based applications with ultra-low latency via the former’s new Wavelength edge service, the companies announced this week at AWS re:Invent, letting organizations realize the benefits of edge computing without having to roll their own edge devices.

The idea is a pretty simple one: Place small data centers running AWS’ software next to Verizon’s 5G points of presence. What this means is that applications running in that 5G coverage area can send their data to those remote edge data centers for rapid processing, as opposed to traveling across Verizon’s network, to the Internet at large, to AWS, and all the way back down the chain.

Tags: [edit]

Amazon’s initial foray into the heavily hyped world of quantum computing is a virtual sandbox in which companies can test potential quantum-enabled applications and generally get to grips with the new technology, the company announced Monday.

The product is named Braket, after a system of notation used in quantum physics. The idea, according to Amazon, is to democratize access to quantum computing in a small way. Most organizations aren’t going to own their own quantum computers for the foreseeable future; they’re impractically expensive and require a huge amount of infrastructure even for the limited proof-of-concept models at the current cutting-edge.

Ampere Computing, the semiconductor startup led by former Intel president Renee James that designs Arm-based server processors, is preparing to launch its next-generation CPU by mid-2020.

The upcoming chip will have 80 cores, much more than the 32-core processor the company shipped last year and vastly more than x86 CPUs by Intel and AMD. Ampere’s design is different. Instead of multiple threads per core, each core is single threaded.

Much of the hyperbole around the Internet of Things isn’t really hyperbole anymore – the instrumentation of everything from cars to combine harvesters to factories is just a fact of life these days. IoT’s here to stay.

Yet despite the explosive growth – one widely cited prediction from Gartner says that the number of enterprise and automotive IoT endpoints will reach 5.8 billion in 2020 – the IoT market’s ability to address its known flaws and complications has progressed at a far more pedestrian pace. That means ongoing security woes and a lack of complete solutions are most of what can be safely predicted for the coming year.

IDG Contributor Network: Dell Tech’s PowerOne approach to hybrid cloud
» ‎ Network World

Tags: [edit]

Hyper Converged Infrastructure is going through a period of dynamic shifts and disruption, hybrid and multi cloud architectures are also transforming how people think about infrastructure. And with this I am watching the vendor landscape go through a period of significant transformation.

For most traditional IT vendors, established norms and product roadmaps are in a state of flux as product lifecycles are being compressed. And new mega trends – AI, ML, containers and 5G, to name a few – are disrupting how IT is provisioned, managed and consumed.

We are also entering a market cycle of increased “coopetition,” where traditional on-premises vendors such as IBM, Dell Tech, HPE and Cisco (among others) are having product roadmaps and revenue projections upended by hyperscale cloud providers such as AWS, Microsoft with Azure and Google Cloud Platform. While these companies are continuing to work together strategically, it’s also easy to recognize that market conditions are yielding an increased level of competition among these same organizations. These shifts are driving the incumbent infrastructure vendors to make bold moves to stay relevant and continue to drive the growth so craved by shareholders and the innovation desired by their largest customers and users.

DXC Technology, the massive service provider formed in the 2017 merger of HPE Enterprise Services (formerly EDS) and Computer Sciences Corp., has a new CEO who is focused on shedding distraction businesses and focusing on core businesses of IT outsourcing.

That means looking at "strategic alternatives," including the possible divesture of three of its businesses it feels are a distraction and slowing the company’s growth. The company feels most IT apps and services will remain on-premises and will focus on supporting that business.

Last week’s conference call with financial analysts to discuss Q2 earnings was the first for new CEO Mike Salvino, who joined the company in September after 22 years at Accenture. DXC did not have a good quarter. The company reported non-GAAP earnings of $1.38 per share, which fell short of the consensus estimate of $1.44 and way down from EPS of $2.02 from the same quarter a year ago. Revenue of $4.85 billion fell short of the analyst estimate of $4.92 billion.

Tags: [edit]

It’s always difficult to tell how fast your business will grow, and hence how quickly you’ll need to scale your network and other IT infrastructure. When it comes to software-defined wide-area networks (SD-WAN), the scalability issue is particularly thorny because of the myriad factors that play into the equation.

Some will tell you scaling an SD-WAN is a simple matter of adding appliances, but that is far from the case, says David Greenfield, Secure Networking Evangelist with Cato Networks. Cato provides a cloud-based SD-WAN service, so Greenfield is well-versed in the factors that make SD-WAN scalability so challenging. In this post, we’ll examine a handful of them.

BrandPost: SD-WAN as MPLS Replacement: Why the Internet Isn’t Enough
» ‎ Network World

Tags: [edit]

As companies turn to SD-WAN services, they’re often looking to migrate away from expensive MPLS services at the same time and employ Internet services instead. But the public Internet doesn’t provide the kind of predictable performance that enterprises need, and it can introduce unacceptable security risks.

A sound alternative is a global, privately managed cloud-based network that can provide the consistent performance and low latency that enterprises demand, but at a fraction of the cost of MPLS – and with security built in. To get a sense for the requirements companies should look for in a managed cloud backbone to make for a successful SD-WAN migration, I spoke with Dave Greenfield, Secure Networking Evangelist with Cato Networks, which has built just such a backbone.

Tags: [edit]

As interest in software-defined wide-area networks (SD-WAN) continues to rise, enterprises are coming face to face with the challenge of planning an SD-WAN migration that will serve the company today and into the future, forcing them to deal with a number of unknowns.

The uncertainties include how fast the company will grow, whether new sites will be required, and what revenue and cash flow will look like. Existing and emerging security threats must be considered as well. About the only certainty is that cloud services will continually factor into the equation.

Challenges inherent in network future-proofing

Network planning in this kind of environment requires a degree of future-proofing, meaning implementing a network that is comprehensive and agile enough to accommodate new requirements without compromising on service quality or total cost of ownership. But doing so comes with considerable challenges.
