The CCVPN use case allows for the orchestration of an operator’s underlying optical transport network and overlay SD-WAN in a way to support the peering of inter-operator VPN service delivery.
The competitive landscape for managed, on-premises Kubernetes services is becoming increasingly crowded with the likes of Cisco and even Google itself jumping in.
We’ve just added a new ISC2 course, The Systems Security Certified Practitioner.
The broad spectrum of topics included in the SSCP Common Body of Knowledge ensure its relevancy across all disciplines in the field of information security. Successful candidates are competent in the following 7 domains:
The Systems Security Certified Practitioner (SSCP) is the ideal certification for those with proven technical skills and practical, hands-on security knowledge in operational IT roles. It provides confirmation of a practitioner’s ability to implement, monitor and administer IT infrastructure in accordance with information security policies and procedures that ensure data confidentiality, integrity and availability.
Today's Full Stack Journey explores the evolution of networking technology and how it affects engineers. Guest Andrew Hrycaj discuss where the industry is going, personal skill development, getting team members on board with new networking technologies and learning requirements, and more.

A handful of groups in New York City are bypassing large ISPs and building their own community networks, as a way to provide cheaper, and in many cases faster and more reliable service.
NYC Mesh and Silicon Harlem, both about five years old, are among a handful of community-based network providers that are working to provide Internet connection alternatives in New York City. The projects seek to fill in coverage gaps – in terms of both geography and reliability – plaguing incumbent broadband providers.
The nonprofit NYC Mesh, with about a dozen core volunteers and no full-time employees, provides and combination of fiber and wireless Internet access in downtown Manhattan, a large chunk of Brooklyn, and corners of the Bronx and Queens, says organizer Brian Hall.
A monthly payment for service – with average speeds of 80 Mpbs and up to 200 Mbps for some users – is voluntary. Many residential members choose to pay $20 a month, while many businesses pay between $50 and $100, but it’s not required.
Volunteers were inspired to launch the service for a number of reasons, Hall says. They wanted to close the digital divide by providing inexpensive broadband service, and Continue reading
So, you’ve created a compute instance (ie, a virtual machine) on Amazon EC2. Next question: does the instance require access to and/or from the Internet?
Protip: just because you created the instance in the public cloud, i.e. the cloud that you get to over the Internet, it doesn’t mean that your instances all need to sit on the Internet. They can have direct inbound and outbound Internet access, no Internet access, or something in between (which I’ll explain).
The basic building block for networking on AWS is the VPC (Virtual Private Cloud). Within a VPC, you define your IP space, gateways, ACLs, DHCP options, and more. Gateways will be the focus of this article.
Today Cloudflare opened the door on our beta deployment of QUIC with the announcement of our test site: cloudflare-quic.com. It supports the latest draft of the IETF Working Group’s draft standard for QUIC, which at this time is at: draft 14.
The Cloudflare Systems Engineering Team has a long history of investing time and effort to trial new technologies, often before these technologies are standardised or adopted elsewhere. We deployed early experiments in standards such as: HTTP/2,
TLS1.3, DNSSEC, DNS over HTTP, Encrypted SNI, when they were still in incubation. We committed to these technologies in their very early stages because we believed that they made for a safer, faster, better internet. And now we’re excited to do the same with QUIC.
In this blog post, we will show you how you can unlock the cloudflare-quic.com achievement and be some of the first people in the world to perform a HTTP transaction over the global internet using QUIC. This will be a moment that you can tell your grandkids about - if they can stop laughing at your stories of cars with wheels and use of antiquated words like: “meme” and Continue reading
The two vendors are offering connectivity and SD-WAN over Ericsson’s private network. The offering looks similar to Aryaka’s.
Six o’clock already, I was just in the middle of a dream, now I’m up, awake, looking at my Twitter stream. As I do that the Twitter app is making multiple API calls over HTTPS to Twitter’s servers somewhere on the Internet.
Those HTTPS connections are running over TCP via my home WiFi and broadband connection. All’s well inside the house, the WiFi connection is interference free thanks to my eero system, the broadband connection is stable and so there’s no packet loss, and my broadband provider’s connection to Twitter’s servers is also loss free.
Those are the perfect conditions for HTTPS running over TCP. Not a packet dropped, not a bit of jitter, no congestion. It’s even the perfect conditions for HTTP/2 where multiple streams of requests and responses are being sent from my phone to websites and APIs as I boot my morning. Unlike HTTP/1.1, HTTP/2 is able to use a single TCP connection for multiple, simultaneously in flight requests. That has a significant speed advantage over the old way (one request after another per TCP connection) when conditions are good.
But I have to catch an early train, got to be to work by nine, so Continue reading
Today’s hybrid architectures require a combination of monitoring techniques to create a modern, full-stack, hybrid cloud monitoring capability.
In 2018, why are we still talking about legacy Windows applications? Why are we holding onto Windows Servers that are a decade old? The simple answer — the applications on those servers still work, and they still serve a business purpose. But they can become a significant liability.
Many of our customers are containerizing legacy Windows 2003 and 2008 applications today with Docker Enterprise, making them portable to new Windows Server platforms and the cloud with no code changes. These three examples — Jabil Circuit, a bank, and GE Digital, showcase the depth of what you can do with Docker Enterprise to modernize legacy Windows applications.
Jabil, one of world’s most technologically advanced manufacturing solution providers with over 100 sites in 29 countries, has embarked on a digital journey to modernize their technology infrastructure. They have a “cloud-first” strategy that requires modernizing over 100 legacy .NET and Java applications, many of which are running on Windows 2008 and 2012.
They’ve deployed Docker Enterprise and windows containers to successfully migrate the applications from legacy Windows servers to Windows Server 2016 on Microsoft Azure cloud. Now that the first phase is complete, Jabil has Continue reading
The fast pace of webinars continues in October 2018:
There are no on-site events planned until early December:
You can attend all upcoming webinars with an ipSpace.net webinar subscription. Online courses and on-site events require separate registration.
