Cisco goes deep into AWS hybrid cloud with SD-WAN, security, Outposts data center support

Cisco is taking its integration with Amazon Web Services to a new level, announcing plans to integrate its SD-WAN, network services and security wares with the cloud giant's hybrid cloud environment, including its new Outposts offering. Outposts offers AWS-designed hardware that lets customers run compute and storage on premises, while connecting to AWS’s cloud services. Each Outpost has a pair of networking devices, each with 400 Gbps of connectivity and support for 1 GigE, 10 GigE, 40 GigE, and 100 Gigabit fiber connections. AWS announced the general availability of Outposts at its annual AWS re:Invent symposium, held this week in Las Vegas. To read this article in full, please click here

Amazon joins the quantum computing crowd with Braket testbed

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.To read this article in full, please click here

Ampere preps an 80-core Arm processor for the cloud

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.Jeff Wittich, Ampere’s senior vice president of products, said that was by design, to avoid some of the CPU vulnerabilities that crept into x86 chips but also to avoid the “noisy neighbor” problem in cloud service-provider networks.To read this article in full, please click here

BrandPost: Branch Office SD-WAN Availability: Last-Mile Considerations

MPLS is showing its age in the era of digital transformation. SD-WAN’s agility, low cost, and direct branch office cloud access increasingly make more sense for global, cloud-enabled organizations. The big question for many IT leaders is: Can  SD-WANs and their Internet last-mile connections match MPLS’s availability to serve as an MPLS alternative?The short answer? Yes.  Here’s why.MPLS’s Last-Mile Availability Problem MPLS has long been known for its uptime. As managed services that’s no surprise; the telcos do a very good job keeping an eye on the core of their networks. But what’s often a surprise to outsiders is the problem MPLS services have with the last mile. The high cost of MPLS services makes it impractical to equip branch offices with redundant last-mile MPLS connections, and without redundancy delivering on uptime is challenging. And even with Internet backup, failover is often manual or slow enough to disrupt the user experience.To read this article in full, please click here

Displaying dates and times your way

The date command on Linux systems is very straightforward. You type “date” and the date and time are displayed in a useful way. It includes the day-of-the-week, calendar date, time and time zone:$ date Tue 26 Nov 2019 11:45:11 AM EST As long as your system is configured properly, you’ll see the date and current time along with your time zone.[Get regularly scheduled insights by signing up for Network World newsletters.] The command, however, also offers a lot of options to display date and time information differently. For example, if you want to display dates in the most useful format for sorting, you might want to use a command like this:To read this article in full, please click here

How cloud providers’ performance differs

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

IDG Contributor Network: SASE: Redefining the network and security architecture

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

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

Fortinet CEO: Network and security technologies give rise to security-driven networking

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.] In this post, ZK Research had a chance to sit down with the co-founder and CEO of Fortinet Ken Xie to discuss the future of networking and security. To read this article in full, please click here

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

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

BrandPost: Addressing Scalability Challenges with SD-WANs

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
