Not all public cloud service providers are the same when it comes to network performance.Each one’s connectivity approach varies, which causes geographical discrepancies in network performance and predictability. As businesses consider moving to the cloud, especially software-defined wide-area networks (SD-WAN) and multi-cloud, it’s important to understand what each public cloud service provider brings to the table and how they compare.To read this article in full, please click here
In a cloud-centric world, users and devices require access to services everywhere. The focal point has changed. Now it is the identity of the user and device as opposed to the traditional model that focused solely on the data center. As a result, these environmental changes have created a new landscape that we need to protect and connect.This new landscape is challenged by many common problems. The enterprises are loaded with complexity and overhead due to deployed appliances for different technology stacks. The legacy network and security designs increase latency. In addition, the world is encrypted; this dimension needs to be inspected carefully, without degrading the application performance.To read this article in full, please click here

Did you ever wonder who is logged into a Linux system but not know how to find out? This two-minute tip can solve the problem with an introduction to the who command in this 2-minute Linux Tip by Network World blogger Sandra Henry-Stocker.The who command can tell you who is logged in to the network, count them and give a list of them on a single line. It can also show when a system was last booted as well as the run state that the system is in.For those who don’t want to use the formal commands for the various who functions, it’s possible to create aliases that are more intuitive than the commands as written for Linux.To read this article in full, please click here
The network and security industries both continue to evolve at a rate never seen before. Historically, security and network operation teams have worked in parallel with one another, sometimes being at odds with each other's goals.However, that is changing as businesses rely on their networks to operate. It’s fair to say that today, for many companies, the network is the business. As this happens, network and security technologies need to be more closely aligned giving rise to the concept of security-driven networking.[Get regularly scheduled insights by signing up for Network World newsletters.]

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.To read this Continue reading
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.To read this article in full, please click here

Cray will also bring its Cray Programming Environment (CPE) for Arm processors over to the A64FX to optimize applications and take full advantage of SVE and HBM2.To read this article in full, please click here
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.To read this article in full, please click here
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-proofingNetwork 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.To read this article in full, please click here
The promise of SD-Branch is that by collapsing network functionality in branch offices to a unified platform, enterprises can reap benefits in speed of deployment, ease of operation and cost. Since Wi-Fi is a critical piece of local area communications for many branch sites, improved integration, security and management of Wi-Fi is becoming increasingly important to evaluating the benefits of SD-Branch solutions.In branch offices, connected LAN devices and applications must be linked to the Internet via SD-WAN services. By integrating LAN and WAN connectivity, SD-WAN helps to simplify network management with a unified platform as compared to each function having its own unique management console.To read this article in full, please click here
