Users tell what you need to know about SD-WAN

Harrison Lewis wasn’t looking for SD-WAN, but he’s glad he found it.Northgate Gonzalez, which operates 40 specialty grocery stores throughout Southern California, had distributed its compute power for years. Each store individually supported applications with servers and other key infrastructure and relied on batch processing to deal with nightly backups and storage, according to Lewis, the privately held company’s CIO. More about enterprise SD-WAN: 10 hot SD-WAN startups to watch How SD-WAN saves $1.2M over 5 years for a radiology firm SD-WAN deployment options: DIY vs. cloud managed SD-WAN: What is it and why you’ll use it one day How to choose the right SD-WAN transport and why it matters Over time, the company’s needs changed, and it began centralizing more services, including HR and buying systems, as well as Microsoft Office, in the cloud or at the company’s two data centers. With this shift came a heavier burden on the single T-1 lines running MPLS into each store and the 3G wireless backup. Complicating matters, Lewis says, rainy weather in the region would flood the wiring, taking down terrestrial-network connectivity.To read this article in full, please click here

Cray Slingshots Back Into HPC Interconnects With Shasta Systems

While processors and now GPUs tend to get all of the glory when it comes to high performance computing, for the past three decades as distributed computing architectures became the norm in supercomputing, it has been the interconnects that made all the difference in how well – or poorly – these systems perform. …

Worth Reading: SIGPIPE

There is a spectre haunting the Internet — the spectre of SIGPIPE errors. It’s a bug in the original design of Unix networking from 1981 that is perpetuated by college textbooks, which teach students to ignore it. @Errata Security

Flexible deployment options for NSX-T Data Center Edge VM

Each datacenter is unique and is designed to serve the specific business needs. To serve these business needs, you could have a small or a large ESXi/KVM footprint. NSX-T Data Center can be leveraged to provide networking and security benefits regardless of the size of your datacenter. This blog focusses on a critical infrastructure component of the NSX-T Data Center i.e. NSX-T Edge node. Refer to my previous blogs, where I have discussed how the centralized components of a logical router are hosted on Edge nodes and also, provide centralized services like N-S routing, NAT, DHCP, Load balancing, VPN etc. To consume these services, traffic from compute nodes must go to the Edge node.  

These NSX-T Edge nodes could be hosted in a dedicated Edge cluster or a collapsed Management and Edge cluster as discussed in the NSX-T Reference design guide. NSX-T Edge nodes could also be hosted in Compute Cluster in small Datacenter topologies, making it a Collapsed Compute and Edge Cluster design. Please refer to NSX-T Reference design guide to understand the pros/cons of using a dedicated cluster vs a shared cluster. 

In this blog, I will cover various deployment options of NSX-T VM form factor Continue reading

What is a firewall? How they work and all about next-generation firewalls

A firewall is a network device that monitors packets going in and out of networks and blocks or allows them according to rules that have been set up to define what traffic is permissible and what traffic isn’t.There are several types of firewalls that have developed over the years, becoming progressively more complex over time and taking more parameters into consideration when determining whether traffic should or should not be allowed to pass. The most modern are commonly known as next-generation firewalls (NGF) and incorporate many other technologies beyond packet filtering.[ Also see What to consider when deploying a next generation firewall. | Get regularly scheduled insights by signing up for Network World newsletters. ] Initially placed at the boundaries between trusted and untrusted networks, firewalls are now also deployed to protect internal segments of networks, such as data centers, from other segments of organizations’ networks.To read this article in full, please click here

How Telemedicine Is Impacting Healthcare in Rural Nepal

Lack of an affordable and accessible community healthcare is a challenge in rural communities across the globe, and an obstacle in ensuring a healthy population in remote indigenous communities across rural Nepal. Broadband connectivity is opening the door to more accessible and cost-effective patient care by speeding up electronic health records and digital images and increasing mobility with wireless monitoring devices.

This story takes place in Dullu, a place extremely difficult to reach, located in the Dailekh District in mid-western Nepal. In order to reach the area, you need to fly from Kathmandu to Surkhet via a domestic flight and then take an off-road, four-wheel drive across approximately 80 kilometers, many of which are through a mountainous dirt road that remains challenging for both visitors and locals. Despite being fertile land filled with culture and history, Dullu is far behind in the development process and it is still struggling in terms of infrastructure development, including road access, robust communication, and proper health and education services.

The town’s solitary hospital is perpetually understaffed. Budget cuts, inhospitable winters, and lack of medical resources have perennially plagued medical service deliveries to the approximately 45,000 residents who depend on a distant health center.

Berkeley Lab First In Line for Cray “Shasta” Supercomputers

For the past five years, supercomputer maker Cray has been diligently at work not only creating a new system architecture that allows for a mix of different interconnects and compute for its future “Shasta” systems, but has also brought long-time Cray chief technology officer, Steve Scott, back into the company after two stints spent at Nvidia and Google to create a new interconnect, called “Slingshot,” that is the beating heart of the Shasta system and that signals a return of the Cray that we know and love. …

The Benefits of Flexible Multi-Cloud and Multi-Region Networking

A report recently published by 451 Research shows that almost 70% of all enterprises will be using a multi-cloud or hybrid IT infrastructure in a year’s time. As more and more enterprises are swayed into the cloud, companies who have already adopted the cloud are now choosing to go with multi-cloud infrastructure or hybrid architecture for their IT requirements.

The report also showcased that about 60% of all workloads are expected to run using a form of hosted cloud service by 2019. This is an increase of about 45% from 2017. This marks an impressive change from DIY owned and operated services to a cloud or third-party hosted IT services. Therefore, the future of IT services is clearly hybrid and multi-cloud.

Here we explore some of the reasons multi-cloud is a fantastic idea for enterprises when they consider security, flexibility, reliability, and cost-effectiveness.
