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. …

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
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.

It’s not all rainbows and flowers at Google. Hundreds of employees are planning a walkout following a report that the cloud giant rewarded a top exec accused of sexual misconduct.
MEF aims for its SD-WAN service standardization to accelerate sales of SD-WAN products and services like MEF accomplished with Carrier Ethernet service standardization.
Mobile broadband is expected to be the first use case for 5G in Russia. Specifically, operators are looking at ways to ease network congestion in urban areas.
Once you have containers in production certain security measures must be put in place to cover network filtering, container inspection, and host security.
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 company’s got about a year to turn around its Oracle cloud business if it’s going to meet its lofty goals.
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.
A Distributed Denial of Service or DDoS attack is when a number of different computer systems attack a server, website, network resource or a cloud hosting unit. A DDoS attack can be executed by an individual as well as a federal government.
