Conference Packing – The Little Things

It seems like conference season never really ends. Between RSA, Cisco Live, Black Hat, and VMworld, I’m always running around to something. I enjoy being able to meet new people and talk to companies at these events but I also find that a little bit of planning ahead helps immensely.

There’s always a lot of discussion from people about what to pack for a conference. There have been some great posts written about it, like this one from Bob McCouch in 2014. He definitely covers all the important stuff that people would want to know, such as comfortable shoes and a bag big enough to carry extra things just in case you come back with enough fidget spinners to sink an aircraft carrier.

However, I’ve found in recent years that the difference between just surviving a conference and really being prepared involves a few extra items I never thought I’d need to bring back when I first started doing this in 2006. Maybe it’s the Scoutmaster in me, but being prepared has gone from being a suggestion to a necessity. And here are a few of those little necessities that I have found I can’t live without.

First? Aid.

Xilinx closes SolarFlare purchase, promises high-performance networking

Network acceleration appears to be all the rage these days, what with Nvidia acquiring Mellanox, the advent of High Bandwidth Memory 2E targeting networking chips, and now Xilinx closing of its acquisition of low-latency network provider SolarFlare.SolarFlare makes a high-speed network interface card (NIC) using field-programmable gate arrays (FPGAs) to build SmartNICs sold under the X2 brand. These PCI Express network interface cards run network, storage, and compute acceleration, offloading that work from the CPU. SolarFlare also develops application acceleration software to fully utilize the cards.To read this article in full, please click here

Connection Restored

I was embarrassed to realize recently that it’s been well over two years since my last blog post. Life has a way of getting away from you, I suppose. But I’ve decided to try and reboot the blog, and hopefully get back to writing regularly. Let me kick things off my sharing what I’ve been up to recently.

Goodbye, DigitalOcean!

After nearly five years working at DigitalOcean, I made the difficult decision to part ways with the company. In my time there, I was fortunate to work with an amazing team, and witness the truly amazing evolution of a startup company from niche player to major cloud provider. Most of all, I’m thankful to DigitalOcean for the opportunity my role provided in extending from traditional network engineering into development and automation. I’ll miss working with my DO team, but I’m excited to see where the future will take them.

Securing BGP on the host with the RPKI

An increasingly popular design for a data-center network is BGP on the host: each host ships with a BGP daemon to advertise the IPs it handles and receives the routes to its fellow servers. Compared to a L2-based design, it is very scalable, resilient, cross-vendor and safe to operate.¹ Take a look at “L3 routing to the hypervisor with BGP” for a usage example.

While routing on the host eliminates the security problems related to Ethernet networks, a server may announce any IP prefix. In the above picture, two of them are announcing 2001:db8:cc::/64. This could be a legit use of anycast or a prefix hijack. BGP offers several solutions to improve this aspect and one of them is to leverage the features around the RPKI infrastructure.

Short introduction to the RPKI​

On the Internet, BGP is mostly relying on trust. This contributes to various incidents due to operator errors, like the one that affected Cloudflare a few months ago, or to malicious attackers, like the hijack of Amazon Continue reading

Self-organizing micro robots may soon swarm the industrial IoT

Miniscule robots that can jump and crawl could soon be added to the industrial internet of things’ arsenal. The devices, a kind of printed circuit board with leg-like appendages, wouldn’t need wide networks to function but would self-organize and communicate efficiently, mainly with one another.Breakthrough inventions announced recently make the likelihood of these ant-like helpers a real possibility.[ Also see: What is edge computing? and How edge networking and IoT will reshape data centers ] Vibration-powered micro robots The first invention is the ability to harness vibration from ultrasound and other sources, such as piezoelectric actuators, to get micro robots to respond to commands. The piezoelectric effect is when some kinds of materials generate an electrical charge in response to mechanical stresses.To read this article in full, please click here

Extend CI/CD with CR for Continuous App Resilience

This is a guest post written by Govind Rangasamy, CEO and Founder, Appranix.

The radical shift towards DevOps and the continuous everything movement have changed how organizations develop and deploy software. As the consolidation and standardization of continuous integration and continuous delivery (CI/CD) processes and tools occur in the enterprise, a standardized DevOps model helps organizations deliver faster software functionality at a large scale. However, newer cyber threats, evolving regulatory requirements, and the need to protect brand reputation are putting tremendous pressure on IT leaders to effectively protect their customer and business-critical data.

Conceptually, DevOps pipeline approach makes a lot of sense, however, in practice, Site Reliability Engineering (SRE) and Ops teams optimize systems for service reliability and robustness at the cost of delivering new features. The need for software reliability inherently decreases Continuous Delivery (CD) throughput. This conundrum is the biggest challenge for any organization adopting DevOps practices at a large scale today. By integrating and extending CI/CD with Continuous Resilience (CR) to provide protection against multitudes of software reliability disruptions, DevOps teams can confidently deploy new software and not affect resiliency of the systems. In other words, Continuous Resilience is the radical new enabler that gives confidence for Continue reading
