Show 388: The Future Of Networking With Kyle Mestery

The Future of Networking series continues with guest Kyle Mestery.

Kyle is well known to many corners of the networking community including the open source community. He recently re-joined Cisco as a Distinguished Engineer.

We talk with Kyle to get his take on where the packets are flowing over the next several years, including the tech conference scene, open-source networking, the proliferation of open-source networking OSs, what’s inside Open Network Linux (ONL), and cloud-native network functions virtualization.

VMware and VeloCloud announce their networking and security strategy

It’s been a few months since VMware closed its acquisition of VeloCloud, a prominent SD-WAN provider. In that time, the two companies have worked to integrate their products, and recently they announced a unified strategy called the Virtual Cloud Network.The strategy fully supports the migration of applications and data out of the enterprise data center to the cloud and to branches — and with IoT, pretty much anything can be considered a branch today, as VeloCloud claims to have a customer with ocean-going ships as branches. The result is that many enterprises are in a position where their applications are everywhere, and their data is everywhere. This has profound implications on the network that needs to support all of this.To read this article in full, please click here

Dogfooding Cloudflare Workers

Dogfooding Cloudflare Workers

On the WWW team, we’re responsible for Cloudflare’s REST APIs, account management services and the dashboard experience. We take security and PCI compliance seriously, which means we move quickly to stay up to date with regulations and relevant laws.

A recent compliance project had a requirement of detecting certain end user request data at the edge, and reacting to it both in API responses as well as visually in the dashboard. We realized that this was an excellent opportunity to dogfood Cloudflare Workers.

Deploying workers to www.cloudflare.com and api.cloudflare.com

In this blog post, we’ll break down the problem we solved using a single worker that we shipped to multiple hosts, share the annotated source code of our worker, and share some best practices and tips and tricks we discovered along the way.

Since being deployed, our worker has served over 400 million requests for both calls to api.cloudflare.com and the www.cloudflare.com dashboard.

The task

First, we needed to detect when a client was connecting to our services using an outdated TLS protocol. Next, we wanted to pass this information deeper into our application stack so that we could act upon it and Continue reading

European Agenda on Digital for Development: Can the Multistakeholder Approach Help?

The year 2017 was an important milestone in moving forward the European agenda for Digital for Development (D4D). The European Commission (EC) paper on mainstreaming digital technologies into EU development policy and the European Council conclusions on Digital for Development have activated the European development community to share opinions and ideas on how to help bridge the global digital divide.

In the past month, we have had a couple of open events in Brussels to discuss this important issue. The European Parliament’s EPP group hosted a public hearing on Digitalisation for Development to collect ideas and to push for more progress. Two weeks later, the EC held the first multistakeholder meeting for Digital4Development with a focus on Africa.

Building a Balanced Agenda

There are a number of pillars of activities that most stakeholders agree on. These include Internet access with a focus on last mile; Internet as an enabler across different sectors; skills; and entrepreneurship. During the recent meetings, the EC, the national development agencies and the private sector showcased impressive and innovative digitalisation programmes.

However, several stakeholders pointed out that while it is important to continue to invest in Internet access, this is no longer enough. We need Continue reading

Network Automation with Brigade on Software Gone Wild

David Barroso was sick-and-tired of using ZX Spectrum of Network Automation and decided to create an alternative with similar functionality but a proper programming language instead of YAML dictionaries masquerading as one. The result: Brigade, an interesting network automation tool we discussed in Episode 90 of Software Gone Wild.

Cisco embraces Kubernetes, pushing container software into mainstream

Cisco this week took big steps toward helping customers deploy, monitor and manage on-premises and public-cloud production-ready Kubernetes-based container applications.Kubernetes, originally designed by Google, is an open-source-based system for developing and orchestrating containerized applications. Containers can be deployed across multiple server hosts and Kubernetes orchestration lets customers build application services that span multiple containers, schedule those containers across a cluster, scale those containers and manage the container health. [ Check out What is hybrid cloud computing and learn what you need to know about multi-cloud. | Get regularly scheduled insights by signing up for Network World newsletters. ] Because the technology is still relatively new, Cisco says organizations are still challenged to efficiently and confidently utilize Kubernetes as they modernize legacy applications and develop new cloud applications.To read this article in full, please click here

NetQ + Kubernetes: bringing container visibility with the leading container orchestrator

Businesses today have to get applications to market faster than ever, but with the same or less budget. Because of this requirement, modern data centers are evolving to support a change in application delivery. In order to get applications to market faster and increase revenue, applications that were once built as one monolithic entity are becoming segmented and deployed separately, communicating amongst themselves. The pieces of applications, sometimes referred to as microservices, are often deployed as containers. This results in much faster deployment and a quicker update cycle. However, the network teams operating the infrastructure supporting the applications often have no visibility into how their networks are being utilized, and thus are making design, operations and troubleshooting decisions blindly. Now, Cumulus NetQ provides this visibility from container deployments all the way to the spine switches and beyond — accelerating operations and providing the crucial information to efficiently design and operate the networks running containers.

Understanding the challenges of container management

Traditionally, the new application design and deployment method using containers makes operating and managing the infrastructure to support them very challenging. The containers often have to talk with each other within or across data centers or to the outside world. An Continue reading
