  • Cacheable Content Acceleration Commonly referred as CDN, is the core service that brings cacheable content closer to the end-users either geographically or logically by caching content on CDN pops or edges so that is scalable, available and fast to deliver.
  • Non-Cacheable Content Acceleration CDN provider creates a persistent connection between customer origin and the closest CDN edge location to eliminate the tcp 3 way handshake and tcp slow start. then applies a series of tcp optimisations (multIPlexing, etc) between CDN edge locations to deliver non-cacheable content as fast and efficiently as possible to the end-users.
  • Shared CDN Domain SSL CDN provider generates a hostname that is used by customer to HTTPs. domain and SSL certificate belongs to CDN provider.
  • Shared IP SSL Hosting Commonly called SNI, your SSL certificate is hosted in each CDN pop/edge location on a shared IP among other certificates. SNI SSL it’s not supported by some older browsers like IE6 and it’s not as secure as dedicated IP.
  • Dedicated IP SSL Hosting your SSL certificate is hosted in each CDN pop/edge location on a dedicated IP and dedicated resources.
  • RTMP to RTMP Streaming customer origin publishes RTMP format and CDN provider delivers in RTMP format.
  • RTMP to HTTP Streaming customer origin publishes RTMP format and CDN provider transcode to HTTP and delivers in HTTP format.
  • HTTP to HTTP Streaming customer origin publishes HTTP format and CDN provider delivers in HTTP format .
  • Image Optimization CDN transforms customer images on demand at the edge. it can dynamically resize, convert, adjust quality, crop / trim, change orientations and image background colors, and much more.
  • DDoS Mitigation DDoS mitigation is a set of techniques or tools for resisting or mitigating the impact of distributed denial-of-service (DDoS) attacks on networks attached to the internet by protecting the target and relay networks.
  • WAF A web application firewall (or WAF) filters, monitors, and blocks HTTP traffic to and from a web application. a WAF is differentiated from a regular firewall in that a WAF is able to filter the content of specific web applications while regular firewalls serve as a safety gate between servers.
  • Bot Mitigation Bot Mitigation is a set of techniques or tools for resisting or mitigating the impact of bots attacks.
