Capitalizing On Hybrid Cloud In HPC

Cloud computing became an essential infrastructure strategy for nearly every business. Last year Gartner predicted that demand for infrastructure as a service would increase by 36.8 percent. A 2018 McAfee survey found that 97 percent of organizations are using cloud services from public, private or both. Similarly, Rightscale’s 2018 cloud survey showed that 95 percent of enteprises have a cloud strategy, including 51 percent with a hybrid cloud strategy.

Yet, despite the cloud’s ubiquity, and the fact that HPC in the cloud has been possible for more than a decade – Univa commissioned the very first HPC cluster in AWS …

The State of Broadband Connectivity in Canada’s Rural and Remote Regions

In April, the Canadian Standing Committee on Industry, Science, and Technology presented the “Broadband Connectivity in Rural Canada: Overcoming the Digital Divide” to the House of Commons in order to make public their findings and recommendations from a study on broadband connectivity. (In May 2016, the committee adopted a motion to do a study on broadband connectivity, with the primary purpose of developing a plan to improve rural broadband and demonstrate the Internet’s effect on rural economies.) To create the report, the committee used information and conversations from seven meetings, as well as 50 oral and written submissions. Participants in this process represented businesses, small and large service providers, experts, and on-the-ground rural providers. The Internet Society applauds the committee’s use of a consultative process and its effort to provide concrete recommendations to the House of Commons to connect Canada’s rural and remote citizens.

In 2016, the Canadian Radio-television and Telecommunications (CRTC) declared Internet access an essential service and set the minimum performance standard at 50 Mbps download and 10 Mbps upload. At the same time, it estimated that it will take between 10 and 15 years for the remaining 18% of Canadians to reach those Continue reading

Startup RStor promises a new type of distributed compute fabric

Stretching NSX From The Datacenter To The Edge And Cloud

VMware’s $1.26 billion acquisition of network virtualization startup Nicira in 2012 sent ripples through the tech world. Through the deal, VMware, which had made its name as a pioneer of server virtualization technology, planted a flag in the burgeoning software-defined networking (SDN) space that was roiling the traditionally staid networking market.

The deal also put the company at odds with partners like Cisco Systems, which itself was developing a strategy to address SDN and which threatened to upend the business of selling networking switches and routers that had made Cisco a very rich and high-profile tech vendor. It put VMware …

Customizing your text colors on the Linux command line

If you spend much time on the Linux command line (and you probably wouldn't be reading this if you didn't), you've undoubtedly noticed that the ls command displays your files in a number of different colors. You've probably also come to recognize some of the distinctions — directories appearing in one color, executable files in another, etc.How that all happens and what options are available for you to change the color assignments might not be so obvious.[ Also read: Unix tip: Coloring your world with LS_COLORS | Get regularly scheduled insights by signing up for Network World newsletters. ] One way to get a big dose of data showing how these colors are assigned is to run the dircolors command. It will show you something like this:To read this article in full, please click here

Andromeda: performance, isolation, and velocity at scale in cloud network virtualization

Andromeda: performance, isolation, and velocity at scale in cloud network virtualization Dalton et al., NSDI’18

Yesterday we took a look at the Microsoft Azure networking stack, today it’s the turn of the Google Cloud Platform. (It’s a very handy coincidence to have two such experience and system design report papers appearing side by side so that we can compare). Andromeda has similar design goals to AccelNet: performance close to hardware, serviceability, and the flexibility and velocity of a software-based architecture. The Google team solve those challenges in a very different way though, being prepared to make use of host cores (which you’ll recall the Azure team wanted to avoid).

We opted for a high-performance software-based architecture instead of a hardware-only solution like SR-IOV because software enables flexible, high-velocity feature deployment… Andromeda consumes a few percent of the CPU and memory on-host. One physical CPU core is reserved for the Andromeda dataplane… In the future, we plan to increase the dataplane CPU reservation to two physical cores on newer hosts with faster physical NICs and more CPU cores in order to improve VM network throughput.

High-level design

Both the control plane and data plane use a hierarchical structure. The control Continue reading

IDG Contributor Network: Protecting data in a hybrid cloud environment

The past few months have been incredibly instructive on the critical importance of keeping one’s data safe, be it customer data or your own intellectual property.  Data protection itself covers a broad span: Physical data protection Protection from device failure Protection from data loss and breach Not only is data security important to the success and reputation of your company, it can be IT that goes “under the bus” when a security event occurs. This means that your career is literally on the line. As a result, your storage architecture better be up to the task of maintaining the integrity of your data store.To read this article in full, please click here
