Case Study: InMobi achieves 5ms real-time ad serving for 1.5B users with Aerospike

How InMobi serves 1.5 billion mobile consumers with a personal touch

InMobi, a leading independent mobile ad network, powers the Miip discovery platform that ingests terabytes of data to deliver highly personalized mobile ads in real time. As usage scaled globally, the company needed a database with extreme low latency, high availability and easy operations to support billions of daily discovery sessions—requirements that outpaced HBase and made Cassandra impractical due to heavy tuning and operational risk.

InMobi chose Aerospike for its out‑of‑the‑box performance, cross‑datacenter replication and minimal operational overhead. The deployment enabled global synchronization across four data centers, shaved three months off launch, and delivered measurable results: 1.5 billion active users, 138 billion ad impressions per month, peak loads of 150,000 requests/second, consistent ~5 ms lookups within a 20 ms SLA and zero downtime.
