Performance Evaluation and Cost‑Effectiveness of Major Cloud Object Storage Providers

Cloud storage has become one of the hottest products in the cloud computing field, with many providers offering on‑demand, pay‑as‑you‑go services that eliminate the need for extra hardware or dedicated maintenance staff. Because of the abundance of options, an objective performance evaluation is needed to help users choose the right provider.

The test includes six cloud vendors—AWS, Azure, Qiniu, Huawei Cloud, Alibaba Cloud, and Kingsoft Cloud—using the same region (Beijing or Oregon) and a test machine with a 10 Mb bandwidth, CPU utilization below 50 %, bandwidth usage under 70 %, and disk I/O below 60 Mb/s. Apache JMeter 2.13 drives the tests, invoking each vendor’s latest Java SDK to upload and download objects of sizes 1 KB, 10 KB, 100 KB, 1 MB, 10 MB, and 1 GB. The metrics collected are Response Time (RT, 50th percentile) and Transactions Per Second (TPS) for both GET (download) and PUT (upload) operations.

Download (GET) results show that Huawei Cloud excels for small files (1 KB, 10 KB), while AWS, Alibaba Cloud, and Azure perform best for larger files (1 MB, 10 MB). Qiniu and Huawei rank lowest for large‑file downloads.

Upload (PUT) results indicate Huawei Cloud again leads for small files, whereas AWS demonstrates superior performance for larger files (1 MB, 10 MB, 1 GB). Kingsoft Cloud, Qiniu, and Azure perform poorly, with Azure and Qiniu timing out on 1 GB uploads.

Price data were calculated for a typical mid‑size customer (10 TB storage, 100 GB/day egress, 500 k GET/PUT requests per day) using November 2015 public pricing. Azure is the most expensive, while Qiniu is the cheapest, roughly 2.5 times cheaper than Azure.

Cost‑effectiveness is defined as performance relative value divided by price relative value. Performance relative value combines RT (smaller is better) and TPS (larger is better) ratios, while price relative value uses the vendor’s price compared to Alibaba Cloud. The resulting ranking is: Alibaba Cloud > AWS > Huawei Cloud > Kingsoft Cloud > Azure > Qiniu.

In conclusion, for startups and enterprises transitioning to the internet, selecting the right cloud storage provider is crucial. Users should balance performance, price, ease of use, service quality, security, and regional coverage rather than relying solely on vendor marketing claims.
