Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.
