Data protection overlooked in race for digital transformation - IDC

Nearly half of respondents (49%) from the Asia Pacific (APAC) region suffered an unrecoverable data event in the last three years with 40% of these respondents experiencing a greater direct loss of revenue from tech-related disruptions, according to the findings of an IDC whitepaper commissioned by Zerto, State of IT Resilience.   The IDC research surveyed 500 senior-level IT and business managers from over 10 unique industries and companies of all sizes and geographies about the challenges to achieve IT resiliency and its importance to digital transformation and included respondents from Australia and Singapore.   While the majority of businesses surveyed have a cloud, digital transformation or modernisation project already planned for the next two years, these same businesses rate themselves as immature on resilience objectives.   This gap highlights the current demands on IT teams who are being tasked with cloud and modernisation projects even as they struggle to keep

The restructuring of the networking division of System Integrators

In the past the networking division of a System Integrator sold hardware first and software second. The majority of network switches at layer two were developed using FPGAs with proprietary hardware with CPUs used to develop layer three solutions. Any bundled software was poorly architectured and typically served either as element management or some type of network management. The basis of how it all works has been around since the seventies . All the has happened is that networking has become more complex and simplicity is required . Read the article over at LinkedIn here .

451 Report: The Impact of Cloud and the Internet of Things on Data Centre Demand

  With the growing adoption of public cloud services by enterprises and ever-evolving IT options and priorities – including the growth of mobility and IoT – demand drivers for leased data center space have changed, and will continue to do so.  To better understand enterprises plans and challenges, Vertiv and 451 Research polled more than 700 IT decision makers from various sized companies across the US, Western Europe, China, and India.  The result quantifies the continued shift in IT workloads from on-premise facilities to cloud and colocation and also provides insight into how organizations are making decisions regarding moving capacity off premises. In addition, it reveals surprising insights into the impact IoT is already having, and is expected to have, on IT resources. Access the report at Vertiv over here .

6 Things I Wish I’d Known When I Started in IT Service Management

I’ve been working in IT service management (ITSM) for many years now, and I’ve made my share of mistakes along the way. So I thought it’d be nice to share some of the things that I’ve learned from my mistakes in the hope that they’ll help others avoid them. Here are the top 6 things that Stuart Rance wish he’d known when he started in ITSM:

Spider Mythology and Folklore

Depending on where you live, you probably see spiders starting to emerge from their hiding spots at some point in the summer. By fall, they tend to be fairly active because they’re seeking warmth – which is why you may find yourself suddenly face to face with an eight-legged visitor some night when you get up to use the bathroom. Don’t panic, though – most spiders are harmless, and people have learned to co-exist with them for thousands of years. Read the article over at ThoughCo here .

Nokia's Nuage Takes On Cisco & VMware With 'SD-WAN 2.0'

Like other modern SD-WAN technologies -- including Cisco and VMware -- Nuage goes beyond first-generation SD-WAN, which connected the branch to the central data center. That resulted in a phenomenon sometimes called "tromboning," where traffic from the branch intended for the public cloud has to go to the data center and back to the branch to be secured and managed through network policies. With modern SD-WAN, the branch, data center and public cloud platforms can connect directly as needed, without wasteful side-trips in the middle.  Read the article over at Light Reading here .

5 reasons the IoT needs its own networks

Carriers are rolling out new low-power, narrow-band networks for the Internet of Things. Here are 5 reasons why, and one big potential issue with this strategy.

Hybrid IoT communications could be the best option

In fact, the company, which provides Low Power Wide Area (LPWA) networks, says one could use a hybrid that includes an unlicensed LPWA network along with a licensed, cellular LTE narrowband IoT (NB-IoT) or LTE Cat M1 network solution instead. That way you can support cheap, unlicensed IoT short messaging close up, as is offered by Sigfox and others, and then offload the sensor traffic to more expensive, licensed LTE cellular mobile networks as the devices move off home base, such as what happens in asset tracking, Sigfox says.

5 Ways SD-WAN Outscores Traditional WAN

SD-WAN, short for Software-Defined Wide Area Network, is a cloud-based system that allows businesses a highly improved WAN experience through changes in the configuration at which WAN routers work.   To simplify, SD-WAN is a simple, cost-effective and highly flexible technology that’s fast replacing conventional WAN solutions by enhancing the performance of applications based in the office premises and in the cloud. Here are 5 reasons why businesses globally are opening up to SD-WAN, which is rapidly redefining the way branch offices connect with the head office and with each other.

The Top 4 SD-WAN Myths

Software-defined WAN is hot, but there are misconceptions about the technology. We cut through the hype.   Software-defined WAN has received a lot of buzz of late, for good reason: After all, its slogan is essentially “No more MPLS."  That's enough to catch most IT pros' attention. However, one should look beyond slogans to see what the technology can actually deliver.   I've spent a lot of time talking with different SD-WAN vendors to know more about the technology, their products and capabilities. I do see a lot of benefits of this technology, but at the same time I see a lot of marketing mixed with the technical stuff, promising the moon to customers.   This blog, therefore, aims to clear up some misconceptions and myths about SD-WAN.   But before we dig deeper, let's define what SD-WAN is. SD-WAN makes it possible to bond multiple WAN connections -- Internet, MPLS or any other transport pipe --  effectively making the best use of bandwidth and reduc

The neat little trick SD-WAN uses to make a last mile link faster

Way before anyone else had a 64 bit browser, a little known derivative of Firefox, known as Waterfox was available that had been compiled in 64 bits. It supports all the Firefox addons, of which one of my staple ones in DownThemAll . What is neat about the Addon is its ability to adjust the number of segments for a download. So instead of a single segment, a person is able to adjust to using multiple segments and this dramatically improves download speeds! An example is the Intel WiFi driver for Windows at well over 120MB. Slow as a normal download but chop-chop using the DownThemAll Addon in Waterfox. Read the article over at LinkedIn here .

Combining SD-WAN and the throttling technology used in ISPs

In my days at iBurst we using a number of Cisco P-cubes to prevent congestion on the wireless towers. The iBurst connection was able to squeeze approximately a measly 1 Mb/s out of a modem and any excessive use of P2P, especially bittorrent , on the towers would kill the user experience. The solution was manged by someone we called the ninja, so called because one moment he would be at his desk and the next gone. We always thought he has secret routes through the air conditioning ducts of the building. Like many Cisco products the P-cubes have been flushed into the abyss of Cisco acquisition discards with the current market leader in the sector being Sandvine .

5 important things you need to know about your SD-WAN hood

I wrote about SDWAN and genchi genbutsu a while ago. This is what I wrote: Here is where the Japanese concept of genchi genbutsu plays a role. It's the concept of you need to go and see. I have previously written about it here . You need to develop and design products based on being at the coalface and actually seeing the problems, not hearing about them secondhand. You need your own eyeballs and not a report given to you by an intermediary. Only then do you provide added value and actually solve the real problems. Here I was referring to the people designing SDWAN products but the actual products should actually also subscribe to the same methodology.  Let me explain over at LinkedIn here .

Azure Outage Proves the Hard Way that Availability Zones are a Good Idea

Microsoft Azure started patching a glaring hole in its availability strategy last September, when it started previewing in-region Availability Zones. Its rivals Amazon Web Services and Google Cloud had already been using the multi-zone strategy for some time.   Earlier this month – almost exactly one year later – came a confirmation that multi-zone cloud regions were a good idea that couldn’t be stronger. Lightning during a powerful storm caused a voltage swell in the utility feeds powering one of the Azure data centers in San Antonio, Texas, that overwhelmed the facility’s surge suppressors, knocking out its cooling systems. The “load-dependent thermal buffer” baked into the cooling system for such occasions was eventually depleted. Air temperature inside rose, triggering automatic shutdown of hardware.

Five Forces Driving SD-WAN Migration

Legacy WANs are unfit for the digital era. The public Internet continues to be plagued by congestion and reliability problems caused by exponential traffic growth, bandwidth-intensive applications, and expanding network complexities. MPLS was designed before the cloud and brings along with it high costs, inflexibility, and long deployment times. These deficiencies have given rise to a technology known as SD-WAN.

The business of SD-WAN - from the top down

Why would any one want to change from legacy wide area networking to software defined wide area networking (SDWAN)? See the above infographic for more details about the technology. There needs to be a business reason for it and not a technical one. Techies, the type who don't create documentation , tend to solve problems bottom up. The technology is chosen first, then there is a retrofit of underlying processes to fit with that technology, and finally the business is coerced to wave the wand at the newly acquired widgets. This engagement model is the reason why so many projects around technology fail to deliver on the business value. Simply put the problem that is being solved is not one underpinning business.
