CDN

CDN - Content Delivery Network CDN refers to a geographically distributed group of servers which work together to provide fast delivery of Internet content CDN is a service that caches your website and serves the website from geographically the nearest server which in turn increases the loading speed of the website. A properly configured CDN may also help protect websites against some common malicious attacks, such as Distributed Denial of Service (DDOS) attacks. It does help cache content at the network edge, which improves website performance Edge Location - Location where content will be cached; separate to an AWS Region/AZ Origin- Origin of all the files that the CDN will distribute. This can be an S3 Bucket, EC2 Instance, Elastic Load Balancer, or Route53, or not with AWS Web Distribution - Typically used for websites RTMP- Used for media streaming (adobe flash) Edge Locations are not just read only, you can write to them, too Objects are cached for life of TTL Akamai vs Cloudflare Edge & Origin server Data center Internet exchange point Proxy and Reverse proxy Round-trip time TTL- Time To Live Cache Control - Static and Dynamic GSLB DDoS attack Web Application Firewall (WAF)

• Zipkin is a distributed tracing system. 
• It helps gather timing data needed to troubleshoot latency problems in service architectures. 
• If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration.
