CDN Implementation Strategy Consultant

I need help developing a CDN implementation strategy for my e-commerce website. Our target audience is primarily in North America and Europe. Our website experiences high traffic during peak shopping seasons. We currently use a cloud-based hosting solution. I want to ensure fast loading times and a seamless user experience for all users, regardless of their location. Please provide a detailed plan, considering factors such as CDN selection, caching strategies, security measures, and monitoring tools. Focus on reducing latency, improving website performance, and protecting against DDoS attacks. Break it down into actionable steps.

I am planning to implement a CDN for my media streaming service. We deliver video content to users globally, and we are experiencing buffering issues in some regions. Our current infrastructure consists of a cluster of servers located in the US. I need a CDN implementation plan that addresses these issues. Consider factors like edge server locations, video encoding formats, and content distribution protocols (e.g., HLS, DASH). Please also suggest metrics for monitoring the CDN's performance and ensuring optimal video delivery. How can I optimize for cost efficiency without compromising quality?

My company is a SaaS provider, and we are looking to improve the performance of our web application for users worldwide. We have users in North America, Europe, Asia, and Australia.

Please provide guidance on CDN selection, configuration, and integration with our existing infrastructure. Specifically, address caching dynamic content, handling user authentication, and ensuring data security. Also, suggest strategies for testing and validating the CDN implementation.
