Redis and Memcached Benchmark on Amazon Cloud
Garantia Data, providers of Redis and Memcached as-a-Service-in-the-Amazon-Cloud, published the results of a throughput and latency benchmark for different AWS deployment models:
The first thing we looked at when putting together our benchmark was the various architectural alternatives we wanted to compare. Users typically choose the most economical AWS instance based on the initial size estimate of their dataset, however, it’s crucial to also keep in mind that other AWS users might share the same physical server that runs your data (as nicely explained by Adrian Cockcroft here). This is especially true if you have a small-to-medium dataset, because instances between m1.small and m1.large are much more likely to be shared on a physical server than large instances like m2.2xlarge and m2.4.xlarge, which typically run on a dedicated physical server. Your “neighbours” may become “noisy” once they start consuming excess I/O and CPU resources from your physical server. In addition, small-to-medium instances are by nature weaker in processing power than large instances.
Only two comments:
- it’s not clear if there were multiple instances of Redis used per machine when the chosen instances had multi-cores
- I would have really liked to also have a pricing comparison in the conclusion section
