BrandPost: How best to secure applications in any cloud
» ‎ Network World

Tags: [edit]

Organizations worldwide are digitizing their products, services, and operations and moving applications to the cloud as quickly as possible. This forced—though often not well-planned— acceleration to the cloud is happening for a number of reasons, both internally and externally driven.

IT leaders within organizations are pushing the “go digital” movement because they know it can lead to improvements in product innovation, customer experience, and operational efficiency.

As for external drivers of this digital push, the recent past has the COVID-19 pandemic with the hybrid workforce as the most obvious one. However, there have also been dynamic business issues such as responding to board-of-directors directives or the specter of increased competition that have compelled organizations to ratchet up the use of the cloud to better defend and acquire market share.

Microsoft details its ChatGPT hardware investments
» ‎ Network World

Tags: [edit]

Microsoft investment in ChatGPT doesn’t just involve money sunk into its maker, OpenAI, but a massive hardware investment in data centers as well which shows that for now, AI solutions are just for the very top tier companies.

The partnership between Microsoft and OpenAI dates back to 2019, when Microsoft invested $1 billion in the AI developer. It upped the ante in January with the investment of an additional $10 billion.

But ChatGPT has to run on something, and that is Azure hardware in Microsoft data centers. How much has not been disclosed, but according to a report by Bloomberg, Microsoft had already spent “several hundred million dollars” in hardware used to train ChatGPT.

BrandPost: Extending cybersecurity to employees no matter where they’re working
» ‎ Network World

Tags: [edit]

For many employees, the traditional workplace has evolved over the past 20+ years into today’s work-from-anywhere (WFA) environment. And recently, this evolution—with a boost from 2020’s global pandemic shutdowns—has accelerated at breakneck speed. Currently, many organizations and their IT cybersecurity teams are struggling to keep up with the pace of change.

While IT leadership is desperately trying to provide consistent support and protection for their WFA people, there’s never been a more opportune time for cybercriminals to take advantage of the new challenges, vulnerabilities, and expansion of the attack surface. Evidence of the increase in cyberattacks can be found in a recent global survey commissioned by Fortinet for a WFA study.

Dell offers bare metal cloud via colocation
» ‎ Network World

Tags: [edit]

A new deal between Dell and colocation services provider Cyxtera will enable enterprises to access Dell’s PowerEdge infrastructure for bare-metal deployments in Cyxtera facilities.

“Bare metal” cloud services means you get the hardware with no software loaded. Typically, a cloud services provider offers an operating system, usually Linux, and accompanying infrastructure. With bare metal, you just get CPU cores, memory, networking and storage but no OS. You provide your own environment.

Under the deal, enterprises will be able to deploy Dell hardware through Cyxtera’s enterprise bare-metal service, an on-demand offering that connects an enterprise’s existing on-premises infrastructure with the colocation environment.

Using the at command to schedule tasks on Linux
» ‎ Network World

Tags: [edit]

To schedule a command or script to run at some particular time, the at command is perfect and provides many options for specifying the time you want it to run. It will set the task up to be run whenever you specify, and you can view the scheduled tasks or even change your mind and cancel one of them as you see fit.

The at command differs from cron in that it sets up a command or script to run only once, while cron allows you to set up commands or scripts to be run on a specified schedule – whether every day, once a week, a couple times a month or even just once a year.
at command syntax
Using the at command is relatively easy, though it has a lot of options, particularly on how you specify the time a task should be run. If you specify a time like shown below, the task will be set up to be run the next time you reach 15:27 (3:27 PM), whether that's today or tomorrow.

How network pros can fight being squeezed out of cloud decisions
» ‎ Network World

Tags: [edit]

There's a rumbling in the cloud as network professionals increasingly seek to reclaim what they believe is their rightful place in the enterprise management hierarchy.

Network knowledge is now widespread within many other IT disciplines. "This means it's now sometimes easy for other teams to assume that they know all they need to know about networking, so they don't need to bother the network team," observes Josh Stephens, CTO of multi-cloud network automation provider BackBox.
Network pros have unique perspectives.
When it comes to multicloud decision-making, IT, cloud, cybersecurity, and network professionals all bring different perspectives and talents to the table. "IT teams have a deep understanding of the organization's overall technology, while cloud teams have expertise in cloud-based technology solutions, and cybersecurity teams have a thorough understanding of [cloud] security risks," says Dan Dulac, vice president of solutions strategy at network infrastructure provider Extreme Networks. Combining the insights of these experts, along with network professionals, is the best way for organizations to make informed decisions about their multicloud strategy, he says.

HPE Aruba, Microsoft Azure, and reelyActive speed streaming of IoT data to the cloud
» ‎ Network World

Tags: [edit]
Aruba Networks, Microsoft Azure and open-source vendor reelyActive have teamed-up to make it easier to bring IoT device data to cloud applications.

The package, Aruba IoT Transport for Azure, brings together three separate components to make it work:
- Aruba Access points that incorporate both Wi-Fi and IoT radios to serve mobile connectivity, connect to IoT devices, and function as embedded IT-to-IoT gateways simultaneously and securely.
- HPE Aruba Networking IoT Transport for Azure service that encodes IoT-device data streamed through the access points into a format compatible with Microsoft Azure IoT Hub, which centrally ingests, provisions, and manages device data.
- reelyActive Pareto Anywhere for Microsoft Azure a new free open-source converter that reformats IoT data and units of measurement such as temperature and power into a universal format compatible with Microsoft analytics, Power BI and other Azure applications. The tool abstracts the original data format so that the data seen by applications are intelligible, consistent streams of immediately consumable data in recognizable units of measurement. Azure applications can directly consume data from a heterogeneous mix of BLE, 800MHz and 900MHz EnOcean specialized IoT devices that plug into the USB port on HPE Aruba Networking access points without a dedicated on-premises gateway.
In a nutshell, reelyActive’s open-source data converter lets IoT device data stream securely from Aruba Wi-Fi access points to the Microsoft Azure cloud where Microsoft applications such as Power BI and third-party applications can utilize the data.

Best-of-breed networking: There’s an opportunity for white boxes in the WAN
» ‎ Network World

Tags: [edit]

Everyone wants the best network, so they say, but as usual with “bestness” goals, there’s not much agreement on how to achieve it. Do you go for best-of-breed in your equipment, or maybe for three vendors per product area, or maybe open white-box networks? A bit over three-quarters of enterprises said in 2020 that open networks and white boxes would give them best of breed options, but what’s happened since then seems like a blast from the past, vendor-wise.

Let’s start with an interesting truth. Well over 95% of established enterprises who can look back to the origins of their networks say that they started off with a single-vendor network. Enterprises who launched within the last five years (which are very few) account for almost all those who didn’t start off with one vendor. If you think about it, this is logical, because starting off with networking is daunting enough without adding in the complication of network integration and the management of multiple sources of technology.

When does SD-WAN make sense?
» ‎ Network World

Tags: [edit]

This is an important question, with a simple answer: it depends. And the main thing it depends on is, why an organization wants an SD-WAN in the first place. Answering that goes a long way to answering the size question.

The baseline assumption is that the IT department sees a need for the organization to have a iprivate WAN, rather than every site communicating solely over the public internet.

This is not a trivial assumption any more. As little as a decade ago, it was standard to have a private WAN for even two or three locations, since they would most likely be sharing back-end services of some sort from a common data center. Today, no such assumption can be made. Many companies grow to have many sites without needing private connectivity among them because everything they do is hosted in one or another external cloud. And, as some organizations migrate services out of data centers, they find that they need private WAN links at fewer sites or only at their data centers.

What is power over Ethernet (PoE)?
» ‎ Network World

Tags: [edit]

Power over Ethernet (or PoE) is the delivery of electrical power to networked devices over the same Ethernet cabling that connects them to the LAN. This simplifies the devices themselves by eliminating the need for an electric plug and power converter, and makes it unnecessary to have separate AC electric wiring and sockets installed near each device.

Many enterprises have come to rely on PoE to bring electricity over existing data cables to Wi-Fi access points, firewalls, IP phones, and other infrastructure throughout their networks.

With the public release of ChatGPT and Microsoft’s $10-billion investment into OpenAI, artificial intelligence (AI) is quickly gaining mainstream acceptance. For enterprise networking professionals, this means there is a very real possibility that AI traffic will affect their networks in major ways, both positive and negative.

As AI becomes a core feature in mission-critical software, how should network teams and networking professionals adjust to stay ahead of the trend?

Andrew Coward, GM of Software Defined Networking at IBM, argues that the enterprise has already lost control of its networks. The shift to the cloud has left the traditional enterprise network stranded, and AI and automation are required if enterprises hope to regain control.

What is Multicloud?
» ‎ Network World

Tags: [edit]

An organization takes a multicloud approach when it uses cloud services from more than one provider. That might seem obvious from the name—it's multiple clouds, after all—but the reasons for choosing a multicloud approach can be as varied as the cloud platforms themselves.

Because "cloud" has become such a broad and all-encompassing category, a multicloud environment might include, say, Microsoft 365 SaaS for productivity apps, Google Drive for storage, and Amazon AWS for compute services.

On the other hand, organizations might have a reason to turn to multiple cloud providers for the same function or purpose. And public cloud services are so cheap and easy to get started with that large organizations (or organizations that don't have tight centralized control over IT) might find themselves in a multicloud situation without ever intending to.

MWC analysis: Conditions are ripe for cloud providers to drive faster network services.
» ‎ Network World

Tags: [edit]
Big challenges don’t usually suddenly explode on the scene. There are little symptoms, warning signs that signal developing issues. One place to look for them is a trade show, because there are a lot of buyers and sellers collected in one place. The Mobile World Congress (MWC) that just ended is a good example, because it validated some little signals that networking might be facing a big challenge.
- Back in 2007, Australia created a National Broadband Network (NBN) as a national infrastructure project because access infrastructure was too expensive to support competition and reasonable consumer prices. At MWC, Telecom Italia said that retail pricing pressure and exploding data consumption meant it was “facing a perfect storm.” Ericsson said that the 200 operators in Europe need to consolidate significantly in order to be financially efficient and stable.
- Last year, because consumer willingness to pay for broadband hasn’t grown and their appetite for bandwidth has exploded, European Union operators have asked the union to approve subsidies to them from big tech. Stories spread through MWC that the EU favored the subsidies, called the fair share. An EU regulator suggested that fair-share policies were essential to assure gigabit connectivity by 2030.
- Mobile operators, long the profit stars of carrier services, are looking for a revenue boost or cost reduction. At MWC, Telefonica announced a partnership with Microsoft to support an API program called Open Gateway that the GSMA announced as a means of raising new revenues and perhaps avoid subsidies.
- Equipment vendors’ earnings from service provides have been dropping. At MWC, Nokia’s announced rebranding created a buzz, because it includes less emphasis on service provider networks and more on enterprise networks. But over the last 20 years, the portion of enterprise network budgets that represent new spending to achieve new benefits has dipped from almost half to about 10%.
These are not the signs of a healthy industry. Remember the story of the little Dutch boy who stuck his finger in a hole in the dike and saved the country from a flood? Well, we’re seeing, in all these data points, the signs of a real problem in networking, a lot of leaks in the dike of its business model. Where are the fingers?

It’s a deal to make its DGX systems available through multiple cloud providers, rather than installing the the necessary hardware on premises.

Nvidia sells GPU-based compute systems called DGX Pods. The same processors, networking, and Nvidia’s comprehensive AI Enterprise software stack from the Pods will be available through your browser, rather than sinking six or seven figures into hardware for your data center.

Cisco simplifies cloud-management licensing
» ‎ Network World

Tags: [edit]

Looking to simplify the way enterprises buy its software, Cisco has streamlined the licensing scheme for its Intersight cloud-operations management platform.

The SaaS-delivered Intersight package manages a variety of systems from Kubernetes containers to applications, servers, and hyperconverged environments from a single location.

Cisco said this week it was moving from a four-tiered licensing menu to one with two tiers named Essentials and Advantage.

Under Essentials, Cisco provides full lifecycle operations with proactive support and service for use cases including managing server profiles/policies, managing firmware updates, and proactive health monitoring and security advisories, Mahesh Natarajan, senior director of product management with Cisco’s Compute group, wrote in a blog.

Tags: [edit]

Wi-Fi HaLow, the marketing term the Wi-Fi Alliance has chosen for the IEEE 802.11ah standard, is a long- range, low-power, low-speed version of traditional Wi-Fi. It shows promise with deployment of Internet of Things (IoT) devices such as sensors, wearables, machine-to-machine (M2M) applications, smart buildings, and smart cities.

With the ability to connect low-bandwidth devices to IP networks including the internet, it supports enough bandwidth to handle HD-quality video and can even be used for rural communications and offloading cell phone tower traffic.

Cisco, Intel collaborate to build private 5G services
» ‎ Network World

Tags: [edit]

Cisco and Intel have teamed up on private 5G for enterprise and IOT use cases.

During the Mobile World Conference (MWC) this week, Cisco also made other 5G announcements including its Meraki 5G cellular gateways for fixed-wireless access and linking up with NTT, NEC, and Qualcomm to offer 5G services.

Many enterprises are still kicking the tires on private 5G service, and many will continue to use 4G LTE for a long time, but 5G is definitely drawing interest, according to Patrick Filkins, research manager, with the IoT and Telecom Network Infrastructure group at IDC. “We expect that by 2026, roughly 80% to 90% of enterprises will have incorporated private 5G as part of their network. Some will benefit from the enhanced mobile-broadband aspect, but many will dig into the advanced features yet to come.”

3 things network pros need to tell developers about why the network matters
» ‎ Network World

Tags: [edit]

Of the 47 enterprises I chatted with in December, guess how many were NOT users of hybrid cloud. Zero.

Guess how many ever used another cloud model. Zero.

Guess how many believe they will "move everything to the cloud". Zero.

OK, I realize that you may not have read this sort of thing very often or at all, but I think it demonstrates just how important hybrid cloud is and how little we really know about it. That’s bad in that it’s always a bad thing when something critical is hardly understood, but it could be a good thing for network professionals looking to engage again with their company IT planning process.

BrandPost: The Evolution of Zero Trust Network Access
» ‎ Network World

Tags: [edit]

When cellular phones first came out, all you could do with it was make a call. Over time, as more features were added, such as cameras and internet connectivity, those capabilities became an expected part of the phone itself. Today, even the cheapest $20 retro flip phone includes a camera, texting capabilities, GPS, music, and even the ability to (still) make a phone call.

I think a similar transition is going to happen to zero trust network access (ZTNA). Right now, many ZTNA solutions are offered as an extra service, so that organizations pay per user to access applications in addition to their existing security solutions. But over time, ZTNA will become expected, much like you expect your phone to have a built-in camera. Going forward, ZTNA will simply become a standard part of cybersecurity.

What is a virtual network
» ‎ Network World

Tags: [edit]

A computer network as we usually visualize it involves various cables (Ethernet, fiber optic, coaxial) connecting to appliances like routers and switches, which direct data packets where they need to go.

The rise of Wi-Fi and cellular data networks have replaced some of those wires with wireless signals, but even radio waves are in the realm of the physical, and they connect back to cell towers or Wi-Fi access points.

In the seven-layer OSI network reference model, all of that network equipment, processing, and communication occupies the lowest three layers: Level 3 (the network), Level 2 (the data link), and Level 1 (the physical layer).

Enterprises turn to single-vendor SASE for ease of manageability
» ‎ Network World

Tags: [edit]

Before the start of the Covid epidemic, a traditional WAN architecture with centralized security worked well for Village Roadshow. "Advanced security inspection services can be applied, firewalls can provide separation, and a demilitarized zone can be implemented," said Michael Fagan, chief transformation officer at Village Roadshow, the largest theme park owner in Australia.

But it required backhauling traffic from remote sites to a data center or hub for security inspection, which can hurt application performance, create a poor user experience, and cost the company in productivity, he said.

When the pandemic led the company to transition to a hybrid workforce, with most people working from home or from a remote site, it prompted Village Roadshow to rethink its network and security approach.

AMD issues firmware fixes for Epyc, Ryzen processors
» ‎ Network World

Earlier this month AMD quietly disclosed 31 new CPU vulnerabilities affecting both its Ryzen desktop chips and EPYC data center processors. AMD disclosed the flaws in coordination with several researchers, including teams from Google, Apple, and Oracle.

AMD typically releases vulnerability findings twice a year, in May and November, but decided to release the fixes early due to the relatively large number of new vulnerabilities and the timing of the mitigations.

Despite the severity and number of flaws, AMD posted the lists to its security page. The flaws include BIOS/UEFI revisions that AMD has distributed to its OEMs. Since every OEM has a different BIOS/UEFI, it’s best to check with your motherboard maker or system vendor to see if you need the updates.

What is hybrid cloud computing? The benefits of mixing private and public cloud services
» ‎ Network World

Tags: [edit]

A hybrid cloud is a computing platform built from both private and public cloud components. A public cloud is what usually comes to mind when we talk about cloud computing: storage and compute resources offered by a vendor to customers who pay on a metered basis and don't have to worry about provisioning and managing the underlying infrastructure.

One drawback to using public cloud resources is that they often run in virtualized environments, and customers share hardware and other resources. As an alternative, a customer could set up a private cloud themselves on their own infrastructure, offering the same sort of flexible access to compute resources to internal users.

Global Microsoft cloud-service outage traced to rapid BGP router updates
» ‎ Network World

Tags: [edit]

Outages that made Microsoft Azure and multiple Microsoft cloud services widely unavailable for 90 minutes on Jan. 25 can be traced to the cascading effects of repeated, rapid readvertising of BGP router prefixes, according to a ThousandEyes analysis of the incident.

The Cisco-owned network intelligence company traced the Microsoft outage to an external BGP change by Microsoft that affected service providers. (Read more about network and infrastructure outages in our top 10 outages of 2022 recap.)

Multiple Microsoft BGP prefixes were withdrawn completely and then almost immediately readvertised, ThousandEyes said. Border gateway protocol (BGP) tells Internet traffic what route to take, and the BGP best-path selection algorithm determines the optimal routes to use for traffic forwarding.

Linux systems support a number of file editors – like vi, vim, neovim, ne, GNU Emacs etc. But you can also install an editor that allows you to view the contents of and make changes to binary files--hexedit.

With hexedit, you can edit images, executables and other binaries, though you have to know a lot about the format of the file you’re editing to make valid changes that don't disrupt the file's format. After all, you'll be editing one byte at a time. This is not meant to imply that you can't use this command for viewing or editing text files. There's just little or no reason to do that.

Your network is the heartbeat of the user experience. When it goes down, employees and customers get frustrated, which can lead to reduced productivity, abandoned sales, and other unwelcome business results. And there’s further frustration if users must call or submit a support ticket to IT. This extra step slows resolution. How can an organization avoid this scenario?

The answer is experience-first networking, which includes a strong network infrastructure with visibility into how it’s performing. This approach provides the best possible experience for network operators who must keep the network heartbeat thrumming, as well as end users who keep the business moving.

» ‎ Network World

Tags: [edit]

By: Gabriel Gomane, Senior Product Marketing Manager, Aruba, a Hewlett Packard Enterprise company.

Environment, social, and governance, or ESG, has become a hot topic in corporate strategy as a key component to driving shareholder value and interest. Sustainability, in particular, is often considered the main focus to attain ESG goals due to growing climate change concerns. That strategy, however, must look beyond traditional methods and expand to encompass IT and corporate computing practices, which in turn can drive a significant chunk of an organization’s carbon footprint through its vast energy needs.

In a recent Gartner survey, CEOs considered environmental sustainability as a key differentiator and placed environmental sustainability in the top 10 strategic business priorities. Additionally, 74% of CEOs agreed that increasing Environmental, Social and Governance (ESG) efforts attract investors toward their companies[1].

IDC: With possible recession looming, IT pros plan spending adjustments

Tags: [edit]

Facing what they perceive as an inevitable recession, IT planners are moving ahead with infrastructure investment but also calculating how to shift priorities if spending cuts become unavoidable, according to monthly surveys by IDC.

Roughly 81% of respondents expect their spending to stay the same or increase for 2023, despite anticipating economic “storms of disruption." The results are based on surveys conducted in November and December 2022 of more than 800 IT decision makers in North America, Asia/Pacific, and Europe.

Cloud spending is increasing, and an IDC Quick poll of 69 CIOs from its global CIO Executive Council conducted in December found two-thirds of them are already spending more on cloud services than they budgeted. The two studies are cited in the IDC report “Early 2023 Cloud Budget Outlook: Aligning IT Spending with the Business Conditions” published this month.

Working with image files on the Linux command line
» ‎ Network World

Tags: [edit]
While the best way to view or manipulate image files on Linux is to open them on your desktop for viewing or manipulating with tools like Gimp, there are quite a few ways to get important details on the command line.
Identifying image type by file extension
In general, image files can be identified on the command line by listing their names. Clearly ".jpg" represents a jpeg file, ".png" a portable network graphics file, ".gif" a graphics interchange format file, ".tiff" a tagged image file and so on.
```
$ ls -l images 
-rw-rw-r--. 1 shs shs  256093 Jul 15  2018 mycats.jpg
-rw-r-----. 1 shs shs  784238 Jul 15  2018 mycats.png

-rw-r-----. 1 shs shs    8853 Jul 15  2018 arrow.png
```
Nearly all of the time you can rely on file extensions accurately reporting the file type, but there's more you can do with additional commands.
