Aerospike's patented Hybrid Memory Architecture (HMA) offers superior performance, scalability, and sustainability compared to Redis. Aerospike reduces operational and environmental costs by using fewer, "fatter" cluster nodes that combine DRAM and SSDs/flash storage, eliminating the need for more servers, energy-intensive operations, and cooling requirements. This results in lower infrastructure costs, reduced carbon footprint, and improved performance with predictable sub-millisecond latencies. With Aerospike, businesses can scale vertically without sacrificing performance, use storage efficiently, simplify persistence and storage, and enjoy a sustainable solution for real-time database needs, outperforming Redis in key areas such as node efficiency, TCO savings, energy savings, and reduced cooling requirements. Real-world examples demonstrate the benefits of switching to Aerospike, including Adjust's 85% infrastructure savings, ironSource's improved performance and sustainability with fewer servers, TomTom's 93% reduction in operational costs and 86% reduction in carbon footprint, and AppsFlyer's scalability challenge overcome by migrating to Aerospike.
