Improving our CDN: Four new POP locations – and more on the way

cdn graphGood coverage of our Content Delivery Network (CDN) is key to our customers. The more Points of Presence (PoPs) our CDN has, the better you will be able to serve your end users. As part of our continuous CDN upgrade program, I’m proud to announce that we have opened a further four new PoP locations during the last couple of months.

We have prioritized the following strategic locations:

LeaseWeb Application Security introduction

DDoS attacks and other forms of cybercrime are becoming more and more frequent. That’s why we recently launched a new service called LeaseWeb Application Security. Here’s a quick video-tour of the easy-to-use dashboard from which you can adjusts your security situations, monitor suspicious traffic, respond to threats and more.

LeaseWeb Application Security is further augmented by a 24/7 Security Operation Center that reacts to every incoming attack. With the help of the Security Operation Center, you can constantly analyze your vulnerability and mitigate threats with a high degree of customization. For real-time mitigation of spammers, data breaches and DDoS attacks, application security experts are available 24/7.

LeaseWeb CDN Tutorial: Analytics Introduction

LeaseWeb introduces third generation CDN: multi carrier rack

cdn graphAs a CDN operator, we are continually pioneering new technologies in order to improve performance and lower our cost base.

In this context, we have launched several generations of CDN PoPs. The first generation connected the CDN servers to several carriers via LeaseWeb’s routers. The router ports found the best and fastest route available. In September 2014, we introduced a second generation of PoPs, which complemented the first. The second generation connected the CDN directly to one carrier. This saves costs because the LeaseWeb routers are no longer in between. Unfortunately, in this scenario there is no redundancy advantage since we connected to one carrier only. So even though the CDN PoPs complemented our platform and performed well, they did not allow us to grow at the pace we needed to.


CDN-PoP_2Finally, we can now proudly present our third generation multi-carrier PoP combining the best of both worlds. Using smart, pioneering SDN technologies that we developed in-house, we are exploiting switches that are actually performing routing tasks without the need of using expensive routers.

The multi-carrier PoP routes traffic to either the LeaseWeb network infrastructure (from which we use the peering destinations) or directly to a variety of other carriers available according to their performance. This way, the multi-carrier rack boosts content speed delivery to end users, while at the same time reducing infrastructure and network costs to the bone.
Furthermore, the cherry on top of the cake is that the new multi-carrier PoPs will host our dynamic Anycast DNS platform. The combination of both actions shows improvement by a factor 3 of our content delivery performance both in throughput and latency.

The multi-carrier rack will first be deployed in Miami this August. The rest of the CDN platform will be fully migrated in the following months. By the end of the year, all of LeaseWeb’s customers worldwide will be able to reap the benefits and get more speed and offload than ever before!

LeaseWeb CDN First Anniversary: We’ve only just begun!

What a year! Successfully launching a brand new CDN service from scratch in such a competitive environment has been a tremendous achievement. And now the LeaseWeb CDN team is looking forward to presenting you with yet more new features next year as we continuously improve it. We’re really excited to see how much we’ve accomplished in such a short period of time and it’s been a thrilling experience to be part the team that made it happen.

Here are just a few of the things we’ve achieved:

Four trends straight from the IBC 2014 convention floor

IBC 2014From 12-16 September, the annual International Broadcasting Conference (IBC) was held in the RAI (conference center) in Amsterdam.

LeaseWeb was present and it was a great opportunity to meet many of our customers in person, as most of them usually purchase their cloud, bare metal or CDN services from us online. Gathering their feedback, hearing directly about their growth and their projects and the traditional canal boat ride was really great. It was so encouraging for all our teams that we feel full of energy to innovate again and again. So thank you for the great time and for the trust placed in our CDN solution.

What does next-generation CDN really mean?

For IT teams tasked with managing web applications, optimizing performance often comes to mind. Consequently, the solution of using a CDN imposes itself naturally. A CDN is dedicated to optimize performance and offload the origin site, being deployed on global locations and overcoming inefficient internet protocol.

But the next question is: how does a CDN optimize its own performance and ensure it makes the best out of its hardware?

At LeaseWeb, our cloud hosting experience allowed us to build a strong expertise in complex hardware and network management. We’ve come across all kinds of systems and we extracted all this knowledge to select and build the best possible platform, exclusively dedicated on accelerating each byte that goes through our platform. All of these efforts combined resulted in our CDN offering:

  • Faster web experience for a great end-user experience
  • High availability, balancing resources within PoPs
  • Scalability in order to handle peaks
  • Security of the content on the origin site safeguarded 24/7

We employ the best Linux System Engineers money can buy, and these experts are able to do magic with Linux on commodity hardware. Well … its commodity hardware for us, but probably not for anyone else, as LeaseWeb is able to buy large quantities of cutting-edge servers specially built to order. We work closely with manufacturers, so we even request special firmware’s to be loaded into the hardware. Moreover, we use cutting-edge network equipment that we buy in enormous quantities, as we operate our own 4.0 Tbps network, and carefully select them based on their price/performance ratio.

Our load balancer technology is a typical example of our technical excellence. These Linux boxes are equipped with 40 Gbit network capacities, provided by two dual 10GE cards. With these cards, the server can easily handle over 3.5 million packets per second (PPS) and a throughput of over 18.5 Gbit per second. This effectively utilizes the network cards for more than 90 percent, at an average packet size of less than 1500 bytes.

Each load balancer is capable of forwarding HTTP (layer 7) traffic, while doing deep packet inspection (DPI) without slowing down the traffic. The load balancers look at the HTTP URL and the headers to decide where to forward the request. These machines have one CPU per dual interface network controller, and by adjusting the interrupt strategy and assignment to the various cores, we optimize the throughput, while making sure the latency is not affected.

To conclude, we are glad to say that we are currently operating the smartest CDN platform in the world, which is able to offer lightning-fast throughput at a fraction of the cost of other CDNs, with all the standard features included.
You should benefit from this as well. Visit our website now, and request a trial account so you can get started immediately. My developer colleagues in the CDN team and me are looking forward to be challenged, and can’t wait to hear your story.
