European supercomputing centers are known for deploying innovative architectures and working on cutting-edge applications, but the sheer number of these systems lags rather far behind the U.S. …

Whenever you get into a conversation about exotic travel or ponder visiting the four corners of the globe, inevitably you end up discussing Ulaanbaatar in Mongolia. Travelers want to experience the rich culture and vivid blue skies of Mongolia; a feature which gives the country its nickname of “Land of the Eternal Blue Sky”.
Ulaanbaatar (or Ulan Bator; but shortened to UB by many) is the capital of Mongolia and located nearly a mile above sea level just outside the Gobi Desert - a desert that spans a good percentage of Central Asia’s Mongolia. (The rest of the Gobi Desert extends into China). The country is nestled squarely between Russia to the north and China to the south. It’s also home to some of the richest and ancient customs and festivals around. It’s those festivals that successfully draw in the tourists who want to experience something quite unique. Luckily, even with all the tourists, Mongolia has managed to keep its local customs; both in the cities and within its nomadic tribes.

History also has drawn explorers and conquerors to and from the region; but more on that later.

David Ulevitch, who was once in charge of Cisco’s security business, is leaving to become a general partner at Andreesson Horowitz.
Three companies opened the OCP Experience Center for testing new and proposed OCP technologies and for conducting demonstrations of open OCP hardware designs.
The new facility plays into the data center provider’s plan to pull hyperscale cloud deals away from competitors including Equinix.
eBay ditches OpenStack in favor of Kubernetes and Docker; AT&T awards 5G contracts; Arista makes second acquisition.
What is SDN ? SDN Definition varies from Vendor to vendor ,commonly the architecture of SDN defined by each vendor includes use of different technology to make network automate, flexible, agile, dynamic ,scalable and most importantly cost effective.
I was going through Network automation article and found the different technology/trends which are some or other way often thought of a SDN, or are important part of SDN discussion .It’s good to go through it :-
OpenFlow : Its low level protocol used to decouple the control plane from the data plane.
NFV Network function Virtualization: It refers to taking functions that have traditionally have been deployed as hardware ,instead deploy them as software.
Virtual Switching :They are software based switches VDS(VMware Distributed switch ) ,AVS(cisco application virtual switch ),VSS(VMware Std. switch) etc. that resides in hypervisor kernel providing local network connectivity b/w virtual machines.
Network Virtualization: It refers to software-only overlay-based solution. A key characteristic of these solutions is that an overlay-based protocol such as Virtual eXtensible LAN (VxLAN) is used to build connectivity between hypervisor-based virtual switches. This connectivity and tunneling approach provides Layer 2 adjacency between virtual machines that exist on different physical hosts independent of Continue reading
Here at Cloudflare, we rely on a set of productivity tools built by Atlassian, including Jira and Confluence. We secure them with Cloudflare Access. In the past, when our team members wanted to reach those applications, they first logged in with our identity provider credentials to pass Access. They then broke out a second set of credentials, specific to Atlassian tools, to reach Jira. The flow is inconvenient on a desktop and downright painful on a mobile device.
While Access can determine who should be able to reach an application, the product alone cannot decide what the user should be able to do once they arrive at the destination. The application sets those specific permissions, typically by requiring another set of user credentials. The extra step slows down and frustrates end users. Access saves time by replacing a cumbersome VPN login. However, we wanted to also solve the SSO problem for our team.
We created a plugin, specific to Atlassian, that could take identity data from the token generated by Access and map it to a user account. Our team members log in with our identity provider to pass Access, and then Access could set their user permissions in Jira Continue reading
The etcdadm tool automates the configuration, deployment, and management of etcd clusters used by Kubernetes to store control plane information.
GTT is also working with another recent acquisition, Interoute, to move its SD-WAN to a universal CPE approach with an integrated firewall.
The software-defined platform runs on top of Cohesity, Cisco, HPE, or Dell EMC hyperconverged secondary storage appliances.
The former Sprint executive says that there are too many SD-WAN competitors in the market muddying the message to enterprises.
In the rush to capitalize on NFV many operators have focused purely on the NFV orchestration, but as they move from trials to production, one key piece is missing — management.
Technologies often start out in one place and then find themselves in another. …
