This video provides a comparative analysis of a cloud provider's (Hetzner) newly restructured server offerings, specifically the "Cloud Cost Optimized" and "Cloud Regular Performance" tiers. The creator, confused by the provider's vague descriptions, provisions one server from each category to conduct a series of performance benchmarks and determine if the significant price difference is justified.
The investigation reveals that the "Regular Performance" server is built on newer hardware (AMD EPYC Genoa) compared to the "Cost Optimized" server (AMD EPYC Rome). Benchmark results show a modest 10-20% improvement in CPU and memory performance for the higher-priced tier. The most substantial difference lies in disk I/O, where the "Regular Performance" server demonstrates significantly faster read and write speeds, almost doubling the performance in some tests. The creator concludes that for nearly double the price, users get roughly a 30% overall performance boost (plus double the disk space), with the primary advantage being superior disk I/O. The video ends with a critique of the provider's lack of transparency regarding underlying hardware specifications.
Hetzner's New Cloud Tiers: A Performance vs. Price Analysis
0:00 Introduction to the Change: The creator expresses confusion over recent changes to the cloud server offerings, which have been split into two new categories: "Cloud Cost Optimized" and "Cloud Regular Performance," with unclear specifications.
1:10 Two Distinct Tiers: The "Cost Optimized" tier uses older hardware generations, while the "Regular Performance" tier promises newer hardware. For the "Cost Optimized" tier, it's a "dice game" whether you get an Intel or AMD processor.
3:05 Pricing and Setup: A "Cost Optimized" server is provisioned for €3.56 (2 vCPU, 4GB RAM, 40GB SSD), and a "Regular Performance" server is provisioned for €7.13 (2 vCPU, 4GB RAM, 80GB SSD), making it nearly double the price.
6:39 Hardware Revealed: A check reveals the "Cost Optimized" server is running on an AMD EPYC Rome CPU, while the "Regular Performance" server is on a newer AMD EPYC Genoa CPU.
7:24 CPU Performance Test: Using sysbench, the "Regular Performance" server shows a modest 10-20% performance increase over the "Cost Optimized" server in CPU-bound tasks.
8:46 Memory Benchmark: The memory test shows a slight advantage for the "Regular Performance" server, with its bandwidth measuring around 6400 MB/s compared to 5400 MB/s on the cheaper tier.
10:32 Disk I/O is the Key Differentiator: A simultaneous read/write benchmark highlights the most significant performance gap. The "Regular Performance" server achieves much higher disk I/O, with write speeds nearly double that of the "Cost Optimized" server (e.g., ~280 MB/s vs. ~150-200 MB/s).
13:03 Final Value Analysis: The creator concludes that for almost double the price, the "Regular Performance" tier offers roughly a 30% overall performance increase and double the storage space. The upgrade is most beneficial for applications that are sensitive to disk I/O speed.
14:55 Call for More Transparency: The creator wishes the cloud provider would be more transparent about the specific hardware used in each tier to help customers make more informed decisions without having to run their own tests.
