Cloud Spectator: Benchmarks of Bare-Metal and Virtual Cloud

To quantify the performance differential of running Aerospike’s in-memory NoSQL database on bare-metal and virtual cloud infrastructure, Cloud Spectator conducted throughput speed and latency benchmark tests for three different types of workloads on Internap’s bare-metal servers and AWS EC2 I2 class and Rackspace Performance Cloud Servers virtual instances.

Key findings include:

  • Loading Data Workload – This analysis tested “write” speed when loading data into the database, similar to new users populating their account information into a website. Internap outperformed Rackspace by 5x and Amazon by 51 percent on throughput speed. Internap had 77 percent less latency than Rackspace and 56 percent less latency than Amazon.
  • Balanced Workload – This analysis tested a balance of 50 percent database “reads” and 50 percent updates, simulating the activity of an active ecommerce user and corresponding personalization of digital advertising based on that activity. On throughput speed, Internap outperformed Rackspace by 2.7x and Amazon by 50 percent. Internap had 59 percent less latency than Amazon and 32 percent less latency than Rackspace.
  • Read-Heavy Workload – The read-intensive workload, which is associated with applications like content tagging, featured 95 percent “reads” and 5 percent updates. On throughput speed, Internap outperformed Rackspace by 2.5x and Amazon by 61 percent. Internap had 51 percent less latency than Amazon and 48 percent less latency than Rackspace
