We've open sourced our new block storage benchmark suite. This is based on the SNIA SSS (Solid State Storage) PTS (Performance Test Specification) Enterprise v1.1. Specification is documented here: http://www.snia.org/tech_activities/standards/curr_standards/pts

The test suite currently supports 5 of the 8 tests described in the specification. These include IOPS, throughput, latency, write saturation (WSAT) and host idle recover (HIR).

The test suite uses fio to run the tests per the specification. When the tests are finished, it generates PDF and HTML formatted reports similar to those shown in the SNIA specification. Additionally, the test suite includes a save.sh script that allows you to store fio and test results to CSV, MySQL, PostgreSQL or BigQuery, and to store the PDF and HTML test reports to S3, Google Cloud Storage or Azure Blog Storage.

The github repository includes extensive documentation related to how to setup and run the test suite. Check it out here: https://github.com/cloudharmony/block-storage

We've published a new version of the State of the Cloud DNS report which includes a new comparison matrix for primary/secondary DNS XFR support (AXFR, IXFR, TSIG), adds NSONE to the comparison lists, and uses a more robust marketshare analysis technique (using both CNAME and ASN correlations). https://cloudharmony.com/reports/state-of-the-cloud-dns-0714-report

We've spent some time putting this post and companion report together. It covers how to approach comparing cloud compute services and includes performance comparisons of Amazon EC2, DigitalOcean, Google Compute Engine, Microsoft Azure, Rackspace Cloud and SoftLayer.

transparency for the cloud
Introduction
We aim to provide greater transparency to cloud computing using objective and unbiased analysis techniques. We measure the performance of cloud computing services using standard benchmarks and fair and open test methods. We believe in letting the numbers speak for themselves, and do not engage in "bench-marketing".
