Security architecture shields infrastructure but dashboard needs enhancement
The Azure DDoS Protection plan is essential for environments like ours that are highly exposed to potential attacks, especially since DDoS attacks have become common. The security architecture with Azure DDoS Protection is critical for safeguarding our financial organization's infrastructure. Although implementing it is pricier, it is worth using since our applications are entirely in Azure.
Pranay Jain - PeerSpot reviewer
Senior software engineer at Simplifyvms
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.
