Optimizing Environment Setup in Ansible Playbooks

Have you ever seen an Ansible playbook where 90% of the code prepares the environment, and then all the work is done in a few template and assemble modules? Here’s an alternative way of getting that done. Is it better? You tell me ;)

Xilinx unveils open source FPGA platform

The Vitis unified software platform from FPGA vendor Xilinx is the result of five-year project to create software development tools using familiar languages like C++ and Python to develop a wide range of applications for its reprogrammable chip.The beauty of FPGAs (Field Programmable Gate Arrays) is their configurable, adaptable nature. That's also what makes programming them a king-sized challenge. They're difficult to work with for an unskilled programmer who is not well versed in hardware, and they often require esoteric languages.Vitis supports heterogeneous architectures including Xilinx’s Zynq SoCs, MPSoCs, and Versal ACAPs. Vitis is designed to enable highly optimized, domain-specific acceleration to a wide array of applications, from cloud deployments, to machine learning and AI, to IoT and desktop applications. Think of it as being for Xilinx what CUDA is to Nvidia.To read this article in full, please click here

Site-to-Site OpenVPN on VyOS

The tutorial discusses configuration of site-to-site VPN on VyOS using preshared-key. Static key configuration offers the simplest setup, and is ideal for point-to-point VPNs or proof-of-concept testing. The advantages of using static key are simple setup and no X509 PKI (Public Key Infrastructure) to maintain. The disadvantages are limited scalability - one client, one server setup and the lack of perfect forward secrecy - key compromise results in a total disclosure of previous sessions. Also, a secret key must exist in plain-text form on each VPN peer and it must be exchanged using a pre-existing secure channel.

Our lab consists of two remote sites (Picture 1). The router running network OS - VyOS is presented on each side, connecting computers PC and PC2 to to a particular LAN network. The both VyOS routers are configured forOpenVPN site-to-site mode and the routers also perform NAT (PAT) and firewall services.

Worth Reading: Anycast DNS in Enterprise Networks

Anycast (advertising the same IP address from multiple servers/locations) has long been used to implement scale-out public DNS services (the whole root DNS system runs on massive anycast), but it’s not as common in enterprise networks.

The blog posts written by Tom Bowles should get you there. He started with the idea and described his implementation using Infoblox DNS.

Want to know even more? I covered numerous load balancing mechanisms including anycast in Data Centers Infrastructure for Networking Engineers webinar.

High performance computing: Do you need it?

In today's data-driven world, high performance computing (HPC) is emerging as the go-to platform for enterprises looking to gain deep insights into areas as diverse as genomics, computational chemistry, financial risk modeling and seismic imaging. Initially embraced by research scientists who needed to perform complex mathematical calculations, HPC is now gaining the attention of a wider number of enterprises spanning an array of fields."Environments that thrive on the collection, analysis and distribution of data – and depend on reliable systems to support streamlined workflow with immense computational power – need HPC," says Dale Brantly, director of systems engineering at Panasas, an HPC data-storage-systems provider.To read this article in full, please click here

Fast Friday Thoughts – Networking Field Day 21

This week has been completely full at Networking Field Day 21 with lots of great presentations. As usual, I wanted to throw out some quick thoughts that fit more with some observations and also to set up some topics for deeper discussion at a later time.

• SD-WAN isn’t just a thing for branches. It’s an application-focused solution now. We’ve moved past the technical reasons for implementation and finally moved the needle on “getting rid of MPLS” and instead realized that the quality of service and other aspects of the software allow us to do more. That’s especially true for cloud initiatives. If you can guarantee QoS through your SD-WAN setup you’re already light years ahead of where we’ve been already.
• Automation isn’t just figuring out how to make hardware and software do things really fast. It’s also about helping humans understand which things need to be done fast and automatically and which things don’t. For all the amazing stuff that you can do with scripting and orchestration there are still tasks that should be done manually. And there are plenty of people problems in the process. Really smart companies that want to solve these issues should stop focusing on using Continue reading

Network Operators in Latin America and the Caribbean Take Steps to Strengthen Routing Security

2019 has been a very good year for the Internet in Latin America and the Caribbean. In May, during the 31st meeting of LACNIC, several operators pledged to take steps to make routing security, and the Internet itself, stronger. They joined the MANRS initiative, which includes four simple and concrete steps to improve the Internet’s security and reliability. In August, NIC Mexico convened the second meeting of network operators in the country, during which routing security stood out as one of the main issues on the agenda.

The Internet Society also made progress on collaboration with National Research and Education Networks (NRENs) and higher education institutions. During the TICAL 2019 meeting, we offered a workshop on MANRS in collaboration with RedClara, LACNIC, the University of Guadalajara, ANUIES, and the Autonomous University of Yucatán. This workshop was part of a series of virtual sessions started in April, which ended on October 2 during the ANUIES-TIC meeting with a long-term practical workshop.

As we head to the final stretch of the year, the 32nd meeting of LACNIC will be a new opportunity to work with network operators to improve the security of the Internet. From Panama we will advise anyone interested in Continue reading
