Amazon EC2 High Memory Instances: Helping Digital Data Architectures?

Amazon's EC2 High Memory instances for 6 TB, 9TB, and 12 TB of memory are designed to run large in-memory databases within the same Amazon Virtual Private Cloud as connected business applications. This move is aimed at reducing management overhead and ensuring predictable performance. While Amazon's approach involves co-location within a VPC, Aerospike achieves similar results through its hybrid-memory architecture™. The Amazon High Memory Instances cater to in-memory databases in the cloud to serve up hot data, which aligns with both Aerospike and Edge Computing goals of putting data closer to applications for speed. However, Aerospike believes that databases need to play in the entire spectrum of the storage hierarchy, ranging from in-memory to hybrid-memory, flash storage, or even HDD, depending on latency sensitivity and data movement needs between clusters.
