Cisco Live 2019 – Rededicating Community

The 2019 Cisco Live Sign Photo

Another Cisco Live is in the books for me. I was a bit shocked to realize this was my 14th event in a row. I’ve been going to Cisco Live half of the time it’s been around! This year was back in San Diego, which has good and bad points. I’d like to discuss a few of them there and get the thoughts of the community.

Good: The Social Media Hub Has Been Freed! – After last year’s issues with the Social Media Hub being locked behind the World of Solutions, someone at Cisco woke up and realized that social people don’t keep the same hours as the show floor people. So, the Hub was located in a breezeway between the Sails Pavilion and the rest of the convention center. And it was great. People congregated. Couches were used. Discussions were had. And the community was able to come together again. Not during the hours when it was convenient. But a long time. This picture of the big meeting on Thursday just solidifies in my mind why the Social Media Hub has to be in a common area:

Introducing time.cloudflare.com

This is a guest post by Aanchal Malhotra, a Graduate Research Assistant at Boston University and former Cloudflare intern on the Cryptography team.

Cloudflare has always been a leader in deploying secure versions of insecure Internet protocols and making them available for free for anyone to use. In 2014, we launched one of the world’s first free, secure HTTPS service (Universal SSL) to go along with our existing free HTTP plan. When we launched the 1.1.1.1 DNS resolver, we also supported the new secure versions of DNS (DNS over HTTPS and DNS over TLS). Today, as part of Crypto Week 2019, we are doing the same thing for the Network Time Protocol (NTP), the dominant protocol for obtaining time over the Internet.

This announcement is personal for me. I've spent the last four years identifying and fixing vulnerabilities in time protocols. Today I’m proud to help introduce a service that would have made my life from 2015 through 2019 a whole lot harder: time.cloudflare.com, a free time service that supports both NTP and the emerging Network Time Security (NTS) protocol for securing NTP. Now, anyone can get Continue reading

Technology Short Take 115

Welcome to Technology Short Take #115! I’m back from my much-needed vacation in Bali, and getting settled back into work and my daily routine (which, for the last few weeks, was mostly swimming in the pool and sitting on the beach). Here’s a fresh new collection of links and articles from the around the web to propel myself back into blogging. I hope you find something useful here!

Networking

• Mohamad Alhussein shares information on how to add a floating static route to an NSX edge via the NSX REST API.
• Mircea Ulinic shows readers how to use salt-sproxy to take a different approach to network automation using Salt. Normally this would require the use of Proxy Minions, but Ulinic’s post on salt-sproxy shows how this can be done without any Proxy Minions.
• Michael Kashin has published a couple of posts on a project of his called NaaS (Network-as-a-Service). Part 1 is here, and part 2 is here. These two articles are interesting (to me) because they combine both network automation and Kubernetes. Nifty! I’m looking forward to seeing how NaaS evolves.
• David Holder walks through removing unused load balancer IP allocations in NSX-T when used with PKS. Although I Continue reading

Device Configuration Synthesis with NetComplete on Software Gone Wild

When I was still at university the fourth-generation programming languages were all the hype, prompting us to make jokes along the lines “fifth generation will implement do what I don’t know how”

The research team working in Networked Systems Group at ETH Zurich headed by prof. Laurent Vanbever got pretty close. The description of their tool says:

What bugs cause cloud production incidents?

What bugs cause production cloud incidents? Liu et al., HotOS’19

Last time out we looked at SLOs for cloud platforms, today we’re looking at what causes them to be broken! This is a study of every high severity production incident at Microsoft Azure services over a span of six months, where the root cause of that incident was a software bug. In total, there were 112 such incidents over the period March – September 2018 (not all of them affecting external customers). Software bugs are the most common cause of incidents during this period, accounting for around 40% of all incidents (so we can infer there were around 280 incidents total in the pool).

The 112 incidents caused by software bugs are further broken down into categories, with data-format bugs, fault-related bugs, timing bugs, and constant_value bugs being the largest categories. Interestingly, outages caused by configuration errors represented only a small number of incidents in this study. This could be an artefact of that data set in some way, or it might be due to the tool chain that Microsoft uses:

The types of bugs we observed in production are biased by the fact that Microsoft uses effective Continue reading

Carrier services help expand healthcare, with 5G in the offing

There are connectivity options aplenty for most types of IoT deployment, but the idea of simply handing the networking part of the equation off to a national licensed wireless carrier could be the best one for certain kinds of deployments in the medical field.Telehealth systems, for example, are still a relatively new facet of modern medicine, but they’re already among the most important applications that use carrier networks to deliver care. One such system is operated by the University of Mississippi Medical Center, for the treatment and education of diabetes patients.To read this article in full, please click here

Several deals solidify the hybrid cloud’s status as the cloud of choice

The hybrid cloud market is expected to grow from $38.27 billion in 2017 to $97.64 billion by 2023, at a Compound Annual Growth Rate (CAGR) of 17.0% during the forecast period, according to Markets and Markets.The research firm said the hybrid cloud is rapidly becoming a leading cloud solution, as it provides various benefits, such as cost, efficiency, agility, mobility, and elasticity. One of the many reasons is the need for interoperability standards between cloud services and existing systems.Unless you are a startup company and can be born in the cloud, you have legacy data systems that need to be bridged, which is where the hybrid cloud comes in.To read this article in full, please click here

Composability Melts Into Rack Servers

For enterprises that want to take their compute, storage and networking, create fluid pools of datacenter resources and then use software to deploy and use them as needed, Hewlett Packard Enterprise for the past few years have offered them its Synergy composable appliances that include all that hardware capabilities as well as software like OneView for IT management. …

Helium – Venture Capital Con Job or Viable Business ?

The company 'Helium' appears to be attempting to build a national Low Power WAN (LPWAN) carrier network by asking normal people to buy and operate network nodes for them. The hotspot may be purchased directly or bundled with 3rd party IOT products and become nodes in a proprietary LPWAN that mines tokens in a blockchain.

Disposable $100 IoT satellites could swarm Earth’s orbit

Tiny cheap satellites, self-organizing and communicating as a group, could shift the internet of things (IoT) to space. The postage-stamp-sized devices, acting as sensors, just like the ones we see in traditional IoT networks could perform tasks such as mapping or studying Earth, say scientists involved in a recent successful launch of the disposable nanosatellites.The test satellites, essentially just sensors, were deployed in a batch in March. They captured data, communicated with one another, and then after a couple of days in orbit, as was planned, burned up as they reentered the atmosphere.[ IoT in the enterprise: Download a PDF bundle of five essential articles about IoT in the enterprise ] “This is like the PC revolution for space,” says Zac Manchester, an assistant professor at Stanford University, in an article on the school’s website. Manchester invented the ChipSats 10 years ago. It has taken until now, and after a failed attempt in 2014, to get the constellation operational—if just for those few days.To read this article in full, please click here
