Amazon EC2 USA East (N. Virginia) - Climate Details
This page shows the detailed monitoring results for a "m1.small" instance running in the US East zone of Amazon EC2. We measure the performance of the system itself (using short load tests for cpu, memory and disks) as well as inbound and outbound HTTP requests. The last graph shows PING times for this server from probes around the world.

How To Read The Graphs
System Performance: To measure the performance of the virtual servers we run three load tests (for CPU, memory and disk) every 5 minutes. The graphs on this page show the runtimes for these tests. For an ideal server these values would be constant and the graphs would display a horizontal line (more fluctuations mean less performance quality). The intention of this test is to monitor the consistency of the performance: how reliable are the run times of the service over time? Although the three load tests programs use the same binaries for all sites monitored by CloudClimate.com they are not well suited to actually compare the different cloud hosting vendors (the virtual systems' specs are all different). To compare cloud hosting vendors you should always run load tests (that are as close to your own applications as possible) on the vendors' systems.
Inter-Cloud HTTP Requests: We measure the performance of the Internet network connectivity for the cloud servers by performing HTTP requests between all cloud systems. The graphs show the request times for inbound requests. For an ideal server and network environment the measured times should be constant over time. Spikes in the graph are caused by network latencies or connectivity problems.
