Business is booming at IgnitionOne, as companies increasingly shift their advertising budgets from traditional outlets to digital media. IgnitionOne provides a cloud‑based digital marketing suite that brings together the most important pieces of a marketing campaign on a single platform. Its customers rely on the company to help them manage and optimize digital marketing across multiple channels, including search, social media, website interactions, and more.

A key component of IgnitionOne’s marketing platform supports real‑time bidding (RTB) for digital advertising. RTB requires a lot of technologies, applications, and data centers working behind the scenes to process the huge amounts of data required to execute the right bids at the right time. There’s a constant, very high volume of user data streaming to IgnitionOne from sources like Google, Facebook, and Microsoft.

Until recently, IgnitionOne had relied on F5 BIG‑IP hardware load balancers to handle incoming data. But rapid growth in digital marketing and the amount of traffic that comes with it quickly made F5 BIG‑IP too costly.

Because we are dealing with a firehose of data from sources like Microsoft, Facebook, and Google, we needed to come up with a different solution in order to process that amount of traffic. Traditional hardware load balancers, such as F5 BIG‑IP are expensive, and they lacked the flexibility and scale we needed.
– AJ Wilson, Vice President of Operations at IgnitionOne


The team at IgnitionOne looked at different ways of processing the high volume of traffic. One option was to build their own load balancer, but developing it would require a significant time commitment. F5 BIG‑IP had already been ruled out for real‑time ad bidding traffic because of their high cost. Some potential software‑based load balancers were ruled out because they couldn’t scale to handle the amount and bursts of traffic that would be coming in. IgnitionOne needed a new solution that could load balance SSL/TLS traffic, deliver ultra‑fast speed, incur sub‑millisecond latency, and be highly cost‑effective. IgnitionOne didn’t want to have to continuously add hardware to keep pace with growth.

“We found our answer in NGINX Plus,” says AJ Wilson, Vice President of Operations at IgnitionOne. “When we tested NGINX Plus, we were testing a very high volume of traffic and our servers barely even noticed the load. That gave us confidence that we’d be able to deliver with NGINX Plus. We’ve been using it for over a year, and it’s been successful. Ultimately NGINX Plus won on price, performance, and being able to scale enough to handle the load we’re talking about.”

NGINX powers half of the world’s busiest websites, delivering sites and applications with performance, reliability, security, and scale. NGINX Plus provides a complete, software‑based application delivery platform at a fraction of the cost of F5 BIG‑IP. NGINX Plus has the load‑balancing features, performance, and control IgnitionOne needs to manage high volumes of incoming data.

IgnitionOne uses NGINX Plus to load balance traffic for its RTB application, which is built with Java, memcached, and Aerospike. The team has deployed NGINX Plus instances in redundant pairs in both of its U.S. data centers. There are two clusters in each data center, each with an active and passive instance running on bare metal, for a total of eight NGINX Plus instances. IgnitionOne is also in the process of rolling out the same NGINX Plus setup in its Amsterdam and Hong Kong data centers.

High‑Speed Load Balancing With Low Latency

Load‑balancing speed is paramount at IgnitionOne. For RTB, reducing latency at every point in the process is critical. NGINX Plus enables IgnitionOne to process data as quickly as possible.

“Facebook and others have rules that state each transaction is only allowed 100 milliseconds end‑to‑end to process the data and deliver the bid,” explains Wilson. “The faster we can bid, the more bids we can process, the more users we can win, and therefore create better outcomes for our customers. Because every step along the way – the network, DNS, operating systems, load balancers – adds latency, our job on the infrastructure side is to optimize as much as we can so that the application has time to do the lookups and calculations that it needs to do behind the scenes. With NGINX Plus, we get minimal latency for maximum analysis time.”

Scaling with Confidence to Half a Million Requests Per Second

The recognized leader in high‑performance application delivery, NGINX Plus is easily handling IgnitionOne’s “firehose” of incoming, real‑time data, which can reach 500,000 user requests per second over HTTP and HTTPS connections. IgnitionOne uses NGINX Plus to spread the load across 1000 web servers running the open source NGINX software, with each server processing 300 to 600 requests per second.

We selected NGINX Plus because it can scale enough to handle the load that we’re talking about, giving us confidence that we can deliver with the solution. With NGINX Plus, we’re able to process four to five times the volume that we were processing in the past with our F5 BIG‑IP. Although 500,000 requests per second is what we’re handling with NGINX Plus today, and we’re looking to triple that in 2016. We’re confident we can continue to scale easily with NGINX Plus.
– AJ Wilson, Vice President of Operations at IgnitionOne

Just A Fraction of Previous Costs

As a complete software solution, the cost of NGINX Plus is far lower than legacy hardware load balancers and application delivery appliances. In the past, IgnitionOne had to keep adding more and larger F5 BIG‑IP load balancers, which came with numerous features and capabilities that the company had to pay for but didn’t need or use.

“With NGINX Plus, we’re getting massive scale and performance, while also containing costs,” says Wilson. “We’re currently processing four to five times the volume that we were processing in the past, and we’re able to do that for 1/20th or even 1/100th of the cost of F5 BIG‑IP.”

And because NGINX Plus is a software load balancer, IgnitionOne can install it on its own commodity hardware. The IgnitionOne team runs NGINX Plus on bare‑metal HP servers with Intel processors and 10 Gbps network cards, with none of the limitations on throughput or connections imposed by hardware load balancer licenses. Using existing hardware and off‑the‑shelf commodity hardware, IgnitionOne is greatly reducing capital costs.

Expert Advice Leads to Quick and Impressive Results

IgnitionOne got up and running with NGINX Plus in just a few weeks, and used NGINX Professional Services to help. Experts from NGINX Professional Services helped IgnitionOne install NGINX Plus and customize its configuration for exactly their traffic profile. Taking advantage of the award‑winning technical support that comes with an NGINX Plus subscription, IgnitionOne has worked with the NGINX Plus support team over the past year to make even more optimizations.

“With the expert advice from the NGINX team, we are able to reduce load on our servers and improve latency at same time. It has been really nice to have the NGINX team’s rubber stamp on our configuration and setup, and to have access to experts throughout the process,” says Wilson. “We’re happy with our choice of NGINX Plus and how it performs for us.”
