The Super Secret Cloudflare Master Plan, or why we acquired Neumob

We announced today that Cloudflare has acquired Neumob. Neumob’s team built exceptional technology to speed up mobile apps, reduce errors on challenging mobile networks, and increase conversions. Cloudflare will integrate the Neumob technology with our global network to give Neumob truly global reach.

It’s tempting to think of the Neumob acquisition as a point product added to the Cloudflare portfolio. But it actually represents a key part of a long term “Super Secret Cloudflare Master Plan”.

Over the last few years Cloudflare has been building a large network of data centers across the world to help fulfill our mission of helping to build a better Internet. These data centers all run an identical software stack that implements Cloudflare’s cache, DNS, DDoS, WAF, load balancing, rate limiting, etc.

We’re now at 118 data centers in 58 countries and are continuing to expand with a goal of being as close to end users as possible worldwide.

The data centers are tied together by secure connections which are optimized using our Argo smart routing capability. Our Quicksilver technology enables us to update and modify the settings and software running across this vast network in seconds.

Deploy360 at IETF 100, Day 3: SIDR, TLS & Crypto

This week is IETF 100 in Singapore, and we’re bringing you daily blog posts highlighting some of the topics that Deploy360 is interested in. After the focus on IPv6 & IoT during the first couple of days, we’re switching tack today with a focus on routing and crypto matters.

We’re having to wait until after lunch, but then there’s a choice of UTA, SIDROPS or ROLL at 13.30 SGT/UTC+8.

UTA will be focusing on resolving the final IESG comments on the use of TLS for email submission and access which outlines current recommendations for using TLS to provide confidentiality of email traffic between a mail user agent and a mail access server. Next up for discussion are the open issues on a draft related to Strict Transport Security (STS) for mail (SMTP) transfer agents and mail user agents, before consideration of  a draft on an option to require TLS for SMTP.

NOTE: If you are unable to attend IETF 100 in person, there are multiple ways to participate remotely.

Over in SIDROPS, there will be a review of the status of BGP Origin Validation deployment in RENATA: the Columbia National Research and Education Network. This represents the first wide-scale deployment Continue reading

IDG Contributor Network: The benefits of multi-cloud computing

Its application might be a tough concept to grasp, but the idea of multi-cloud computing is a simple one. It’s the choice of a business to distribute its assets, redundancies, software, applications and anything it deems worthy not on one cloud-hosting environment, but rather across several. At its surface, this concept might seem to be rubbing against the grain a bit. For security purposes alone, having all your company’s proverbial eggs in one basket appears the best way to keep your information from suffering leakage. Plus, many cloud-hosting companies will offer perks and discounts when your company use their services in totality.   However, the model of using multiple cloud services to house your business’s functions and features has an impressive list of advantages that can provide security, flexibility, cost-effectiveness and more to increase your business’s efficiency and ensure it stays up and running 24 hours a day. To read this article in full, please click here

Your online freedoms are under threat – 2017 Freedom on the Net Report

As more people get online everyday, Internet Freedom is facing a global decline for the 7th year in a row.

Today, Freedom House released their 2017 Freedom on the Net report, one of the most comprehensive assessments of countries’ performance regarding online freedoms. The Internet Society is one of the supporters of this report. We think it brings solid and needed evidence-based data in an area that fundamentally impacts user trust.

Looking across 65 countries, the report highlights several worrying trends, including:

• manipulation of social media in democratic processes
• restrictions of virtual private networks (VPNs)
• censoring of mobile connectivity
• attacks against netizens and online journalists

Elections prove to be particular tension points for online freedoms (see also Freedom House’s new Internet Freedom Election Monitor). Beyond the reported trend towards more sophisticated government attempts to control online discussions, the other side of the coin is an increase in restrictions to Internet access, whether through shutting down networks entirely, or blocking specific communication platforms and services.

These Internet shutdowns are at the risk of becoming the new normal. In addition to their impact on freedom of expression and peaceful assembly, shutdowns generate severe economic costs, affecting entire economies [1] and Continue reading

Another Reason to Run Linux on Your Data Center Switches

Arista’s OpenFlow implementation doesn’t support TLS encryption. Usually that’s not a big deal, as there aren’t that many customers using OpenFlow anyway, and those that do hopefully do it over a well-protected management network.

However, lack of OpenFlow TLS encryption might become an RFP showstopper… not because the customer would really need it but because the customer is in CYA mode (we don’t know what this feature is or why we’d use it, but it might be handy in a decade, so we must have it now) or because someone wants to eliminate certain vendors based on some obscure missing feature.

Cloud Managed Wireless Solution : Cisco Meraki MR52

Cloud Managed Wireless Systems : Cisco Meraki MR52

Today I am going to talk about the Cisco Meraki solution which is totally a cloud based managed system and the product name is Cisco Meraki MR52. It is based on the next generation wireless systems that can be deployed in various departments like Education systems, Manufacturing units, Offices, Enterprise networks and so on. The way Cisco Meraki works is totally a next generation revolution where all management can be done via cloud and you just need to deploy the hardware in your network to work.

What is the purpose to deploy and how much time it takes to configure Cisco Meraki MR52 ?
Well if you have the requirement to have the wireless network with various SSIDs you should go with the site surveys and on the basis of it you should go with the suitable model of the wireless WLCs. If I talk about the Cisco Meraki cloud managed MR52, It is simple to deploy and self configured via cloud. So you need not to require any resource for the configuration of the Meraki MR52 at the remote sites.

Manage user performance, not the network, with machine learning-based tools

Over the past decade, network management tools have evolved from being fault based to performance based. This has become a critical element in running infrastructure because faults don’t matter as much.That might seem like a strange thing to say, but consider the fact that critical infrastructure such as switches, routers, Wi-Fi access points and servers are deployed in a way to protect against outages. Infrastructure is built so redundantly today that any hardware device can go down and its likely no one will notice.Also on Network World: 7 must-have network tools A bigger problem is managing user performance. Often users calling about a certain application not working well, but when the engineer looks at the dashboard, everything is green. Performance problems are much harder to diagnose and can kill employee productivity. To read this article in full, please click here
