Data-driven development with Cloudflare Mobile SDK

Data-driven development with Cloudflare Mobile SDK

Data-driven development with Cloudflare Mobile SDK
If your app loads critical resources over the network, it's relying on your user's mobile network connection to deliver an engaging experience. Network errors occur in 3 to 12% of app sessions depending on infrastructure reliability and user geography.

How much engagement are you losing in your app to network errors? Chances are, you don't know.

We didn't either, until we built a free tool that helps Android and iOS developers visualize and understand their mobile app's network utilization.

Introducing Cloudflare Mobile SDK

Our SDK helps you identify slowdowns caused by balky or too frequent network calls, so you can focus your development effort on optimizing the lowest-hanging fruit.

Modern app developers already heavily instrument their apps to identify UX impacting events: they measure and collect launch time, session length, crash rates, conversion events, and lots more, using a multitude of different metrics packages and services.

Web developers look at similar data. They also pay tons of attention to their resource waterfall, mapping their critical rendering path, and understanding which resource loads are synchronous, which are not, and which block rendering. JavaScript even exposes an API to collect waterfalls in the browser programmatically.

It's time to bring the same visibility Continue reading

How Do We Connect Everyone to the Internet? An IETF 101 Technical Plenary

How do we connect everyone, everywhere, to the Internet? What role do “community networks” play in helping connect more people? How can we best use wireless spectrum and what are the issues with that? How can satellites fit into the picture? And what is the state of satellite technology? And what about the role of “space lasers”?

All that and more was the subject of yesterday’s featured panel at the Technical Plenary at IETF 101 in London.

Interested to learn more? Watch/listen to the Global Access to the Internet for All (GAIA) session TODAY (22 March) at 1:30pm UTC:

Comment connecter tout le monde à Internet? Une réunion plénière technique de l’IETF 101

Comment connecter tout le monde, partout, à Internet? Quel rôle jouent les «réseaux communautaires» pour aider à connecter plus de gens? Comment pouvons-nous utiliser au mieux le spectre sans fil et quels sont les problèmes avec cela? Comment les satellites peuvent-ils s’intégrer dans l’image? Et quel est l’état de la technologie par satellite? Et qu’en est-il du rôle des “lasers spatiaux”?

What would a regulated-IoT world look like?

The wildfire growth of IoT is arguably the most important trend happening in technology today, but the ease with which bad actors can exploit its manifold security vulnerabilities has been demonstrated many times in just the past couple of years.Despite the generally laissez-faire stance the U.S. takes toward regulating technology companies, the severity of the threat – IoT security issues affect healthcare, infrastructure, transportation and many other crucial parts of society – has some calling for regulation of the IoT.The hands-off approachGiven the speed at which technology, particularly around IoT, develops these days, from drawing board to prototype to production, plenty of people would argue that it’s impossible for a regulatory regime to keep pace.To read this article in full, please click here

Top 6 Features in Windows Server 2019

Because Microsoft has shifted to a more gradual upgrade of Windows Server, many of the features that will become available with Windows Server 2019 have already been in use in live corporate networks, and here are half a dozen of the best.[ Check out REVIEW: VMware’s vSAN 6.6 and hear IDC’s top 10 data center predictions . | Get regularly scheduled insights by signing up for Network World newsletters. ] Enterprise-grade hyperconverged infrastructure (HCI) With the release of Windows Server 2019, Microsoft rolls up three years of updates for its HCI platform. That’s because the gradual upgrade schedule Microsoft now uses includes what it calls Semi-Annual Channel releases – incremental upgrades as they become available. Then every couple of years it creates a major release called the Long-Term Servicing Channel (LTSC) version that includes the upgrades from the preceding Semi-Annual Channel releases.To read this article in full, please click here

Is MLAG an Alternative to Stackable Switches?

Alex was trying to figure out how to use Catalyst 3850 switches and sent me this question:

Is MLAG an alternative to use rather than physically creating a switch stack?

Let’s start with some terminology.

Link Aggregation Group (LAG) is the ability to bond multiple Ethernet links into a single virtual link. LAG (as defined in 802.1ax standard) can be used between a pair of adjacent nodes. While that’s good enough if you need more bandwidth it doesn’t help if you want to increase redundancy of your solution by connecting your edge device to two switches while using all uplinks and avoiding the shortcomings of STP. Sounds a bit like trying to keep the cake while eating it.

VSS Recovery mode

Dual-active Detection (DAD) is designed to prevent a split-brain scenario where both VSS supervisors become active in the event of a VSL link failure. It uses a separate (from the VSL link) secondary communication link to communicate the devices state.
When the VSL link fails the standby switch becomes active and the current active switch is informed of this over the DAD links and goes into recovery mode to stop a split-brain situation occurring.

BrandPost: The Cloud Payoff: Ensuring Hybrid Works for Your Enterprise

As more and more enterprises move to hybrid cloud, there are some interesting relationships among enterprises, Internet and cloud exchanges, and colocation providers to satisfy IT strategies through hybrid clouds.  In its Strategic Roadmap for Data Center Infrastructure, Gartner notes that “by 2019, 80% of enterprises will have an IT strategy that includes multiple Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) providers.” This is up from only 10% in 2015, while “by the end of 2018, 10% of enterprises will close their on-premises data centers entirely.”To read this article in full, please click here

Li-Fi gets office-install at Philips lighting

Broadband data-over-light, sent through lighting fixtures commonly seen in commercial buildings, moves a step closer to possible mass adoption through an apparently functioning smart-office installation in Paris.Li-Fi uses light waves for data communications, as opposed to Wi-Fi, which uses microwave radio. Li-Fi has 10,000 times Wi-Fi radio’s RF spectrum, experts say. The pilot installation by Philips is at a French real-estate company’s office.Philips Lighting, the giant lighting-system maker, says it is now offering Li-Fi modems installed within its existing LED luminaires, such as its downlighters. A luminaire is the building-industry term for a complete lighting fixture.To read this article in full, please click here
