Why AppNexus Uses Aerospike

null

Meet New York’s billion dollar ad tech company, AppNexus. AppNexus is the world’s largest, independent, real-time ad technology platform powering the most innovative trading solutions and marketplaces for Internet advertising.

This powerhouse recently announced a late stage, funding round valuation at $1.2 billion, nearly doubling their funding round in 2013. Flash back over four years ago when Aerospike built their flash optimized, NoSQL database and key-value store based on AppNexus’ need to achieve speed at scale with no downtime and simple scaling leveraging SSDs. In fact, both companies joke about Aerospike being debugged in AppNexus’ offices. That said, we at Aerospike are proud to be a key part of this wildly successful business for over four years.

Why AppNexus choose Aerospike over other databases

“We run Aerospike heavily, peaking at 3 Million reads per second and well over 1 1/2 million writes a second in a very cost effective way. I don’t think there’s any technology we’ve run into that even comes close.”

– Geir Magnusson, CTO of AppNexus

What does AppNexus mean by scale?

2.5 million impressions a second at peak, although we can go much higher, and we see north of 90 Billion impressions per day and this is a 24×7 business with 100% uptime with Aerospike.”

– Geir Magnusson, CTO of AppNexus
