Experts: Enterprise IoT enters the mass-adoption phase

IoT in general has taken off quickly over the past few years, but experts at the recent IoT World highlighted that the enterprise part of the market has been particularly robust of late – it’s not just an explosion of connected home gadgets anymore.Donna Moore, chairwoman of the LoRa Alliance, an industry group that works to develop and scale low-power WAN technology for mass usage, said on a panel that she’s never seen growth this fast in the sector. “I’d say we’re now in the early mass adopters [stage],” she said.

3 Customer Perspectives on Using Docker Enterprise with Kubernetes

We’ve talked a lot about how Docker Enterprise supports and simplifies Kubernetes. But how are organizations actually running Kubernetes on Docker Enterprise? What have they learned from their experiences?

Here are three of their stories:

McKesson Corporation

When you visit the doctor’s office or hospital, there’s a very good chance McKesson’s solutions and systems are helping make quality healthcare possible. The company ranks number 6 in the Fortune 100 with $208 billion in revenue, and provides information systems, medical equipment and supplies to healthcare providers.

The technology team built the McKesson Kubernetes Platform (MKP) on Docker Enterprise to give its developers a consistent ecosystem to build, share and run software in a secure and resilient fashion. The multi-tenant, multi-cloud platform runs across Microsoft Azure, Google Cloud Platform and on-premise systems supporting several use cases:

  • Monolithic applications. The team is containerizing an existing SAP e-commerce application that supports over 400,000 customers. The application platform needs to be scalable, support multi-tenancy and meet U.S. and Canadian compliance standards, including HIPAA, PCI and PIPEDA.
  • Microservices. Pharmaceutical analytics teams are doing a POC of blockchain applications on the platform.
  • CI/CD. Developer teams are containerizing the entire software pipeline based on Atlassian Bamboo.
  • Batch Continue reading

The future of HCI

You may have noticed already but HCI has been on our minds lately. We’ve talked about it in-depth in our recent white paper and JR Rivers, Cumulus Networks co-founder & CTO, has shared more about it in relation to a network of pods in his on-demand webinar. JR will share more about his take in an upcoming Kernel of Truth podcast episode but in the meantime, we’ll get Naveen Chhabra’s, a senior industry analyst at Forrester, opinion on the future of HCI.

We sat down with him recently to discuss this and here’s what he had to say.

Question: Why is the network such a critical consideration in any hyperconverged infrastructure (HCI) deployment?

Let’s look at the major transformational projects the organizations globally are working on. One project that spans all organizations, verticals, and geographies is digital transformation. IT leaders upgrade or acquire new technologies to support these projects. One pertinent issue across a large percentage of projects is that these are still focused on technology silos.

Specific to HCI, organizations have successfully collapsed the compute and storage silo. Network infrastructure is still not integrated to the extent that it could and should be. Firms have the capability, via HCI, Continue reading

NGINX structural enhancements for HTTP/2 performance

NGINX structural enhancements for HTTP/2 performance
NGINX structural enhancements for HTTP/2 performance

Introduction

My team: the Cloudflare PROTOCOLS team is responsible for termination of HTTP traffic at the edge of the Cloudflare network. We deal with features related to: TCP, QUIC, TLS and Secure Certificate management, HTTP/1 and HTTP/2. Over Q1, we were responsible for implementing the Enhanced HTTP/2 Prioritization product that Cloudflare announced during Speed Week.

This is a very exciting project to be part of, and doubly exciting to see the results of, but during the course of the project, we had a number of interesting realisations about NGINX: the HTTP oriented server onto which Cloudflare currently deploys its software infrastructure. We quickly became certain that our Enhanced HTTP/2 Prioritization project could not achieve even moderate success if the internal workings of NGINX were not changed.

Due to these realisations we embarked upon a number of significant changes to the internal structure of NGINX in parallel to the work on the core prioritization product. This blog post describes the motivation behind the structural changes, how we approached them, and what impact they had. We also identify additional changes that we plan to add to our roadmap, which we hope will improve performance further.

Background

Enhanced HTTP/2 Prioritization aims to do Continue reading

meeting madness, ONUG, and software defined

The Traffic Jam Whopper project may be the coolest/dumbest IoT idea ever

People love to eat in their cars. That’s why we invented the drive-in and the drive-thru.But despite a fast-food outlet on the corner of every major intersection, it turns out we were only scratching the surface of this idea. Burger King is taking this concept to the next logical step with its new IoT-powered Traffic Jam Whopper project.I have to admit, when I first heard about this, I thought it was a joke, but apparently the Traffic Jam Whopper project is totally real and has already passed a month-long test in Mexico City. While the company hasn’t specified a timeline, it plans to roll out the Traffic Jam Whopper project in Los Angeles (where else?) and other traffic-plagued megacities such as São Paulo and Shanghai.To read this article in full, please click here

Improving Routing Security: Microsoft Joins MANRS

In November, a routing incident in Nigeria caused Internet traffic to be rerouted through Russia and China. It lasted for just over an hour, but during that time, it significantly affected some cloud and search services globally, including Spotify and Google’s Search. It was one of more than 10,000 incidents, such as route hijacking and leaks, that occurred in 2018. Past events have led to large-scale Denial of Service attacks, stolen data, and financial losses.

The global routing system is the backbone of the Internet. It determines how everything – from email messages to videoconferences to website content – moves from network to network. The November event, caused by a configuration mistake with a small ISP in Nigeria, shows that routing incidents can have significant global effects – impacting the security of the Internet itself.

A number of network operators around the world – including Oracle, GÉANT, and Comcast – have joined MANRS to address these types of routing threats. The Mutually Agreed Norms for Routing Security (MANRS) initiative, supported by the Internet Society, does this through technical and collaborative action across the Internet. Those who join agree to take meaningful action to keep the Internet safe for everyone – Continue reading

Don’t Base Your Design on Vendor Marketing

Remember how Arista promoted VXLAN coupled with deep buffer switches as the perfect DCI solution a few years ago? Someone took Arista’s marketing too literally, ran with the idea and combined VXLAN-based DCI with traditional MLAG+STP data center fabric.

While I love that they wrote a blog post documenting their experience (if only more people would do that), it doesn’t change the fact that the design contains the worst of both worlds.

Here are just a few things that went wrong:

Software-defined far memory in warehouse scale computers

Software-defined far memory in warehouse-scale computers Lagar-Cavilla et al., ASPLOS’19

Memory (DRAM) remains comparatively expensive, while in-memory computing demands are growing rapidly. This makes memory a critical factor in the total cost of ownership (TCO) of large compute clusters, or as Google like to call them “Warehouse-scale computers (WSCs).”

This paper describes a “far memory” system that has been in production deployment at Google since 2016. Far memory sits in-between DRAM and flash and colder in-memory data can be migrated to it:

Our software-defined far memory is significantly cheaper (67% or higher memory cost reduction) at relatively good access speeds (6µs) and allows us to store a significant fraction of infrequently accessed data (on average, 20%), translating to significant TCO savings at warehouse scale.

With a far memory tier in place operators can choose between packing more jobs onto each machine, or reducing the DRAM capacity, both of which lead to TCO reductions. Google were able to bring about a 4-5% reduction in memory TCO (worth millions of dollars!) while having negligible impact on applications.

In introducing far memory Google faced a number of challenges: workloads are very diverse and change all the time, both in job Continue reading
