Industry Analysis Overviews



Pricing Overview

On a bi-monthly basis, Cloud Spectator analyzes the price of 20 different cloud providers. The calculations are based on selection of CPU cores, RAM, and hard disk, as well as a look into the data transfer costs. The pricing analysis takes into account purchases on an hourly, monthly, and yearly basis, and the discounts associated with each purchase duration. A summary of the results can be found here. For a full copy of the report, please visit our Industry Reports page.


Performance Overview

Leveraging open-source benchmark tests, Cloud Spectator tests a variety of cloud providers 4 times a day, 365 days a week, to understand their true cloud IaaS performance over time. The tests compare and analyze various aspects of the server, from overall performance to a deep dive into CPU, RAM, Disk, and Internal Network performance. This ensures both a general idea of server performance and performance relative to specific applications run on the cloud. To view a summary of the findings, please click here.
