I recently moved a smallish business application from two bare-metal servers onto Azure VMs. It's a standard PHP 7.4 application, MySQL, Redis, nginx. Despite the VMs costing more and having twice the spec of the bare-metal servers, it has consistently performed slower and less reliably throughout the stack. The client's budget is too small to spend much time looking into it. Instead, they upped the spec even further, and what used to cost £600 per month now costs £2000.
