Basic concepts

Key Features

• Low Latency, Quick and Stable Content Delivery through massive distribution: CDN utilizes the power of the internet consisting of a network of strategically positioned servers distributed worldwide located. This ensures low latency and overall quick and stable content delivery regardless of the geographic location of a user consuming a service utilizing a CDN, by transferring content closer to end-users, we mitigate latency and withstand traffic peaks.
• Security Enhancements: CDN comes with robust security features by nature like DDoS attack mitigation. In addition, features like bot protection, Web Application Firewall and geo-IP-based features are possible to secure against threats and unauthorized access. By proactively defending against cyber-attacks we strengthen the security of our customers as well as increase their overall availability, building up confidence in their online operations on STACKIT.
• User-Friendly Management: Manage and monitor CDN distributions via the STACKIT Portal, STACKIT API, STACKIT SDK or through the STACKIT Terraform provider.

Functionalities

Caching

A Content Delivery Network (‘CDN’) stores static website content on various servers in its network.
It works as follows:

• A geographically distant website visitor calls your CDN URL. Our DNS will return a CDN node close to the visitor
• The visitor will request the content from our STACK CDN node
• The CDN node will, if present, return the cached content. If no cached content is available, it will call your origin server and fetch the needed resources. The STACKIT CDN node will cache the result and return the newly fetched resource to the visitor
• The next time this visitor or another visitor at this location makes the same request, the STACKIT CDN node, to the origin server, sends the response

Usage

You can use the CDN for:

• Improving Website Performance: by caching static content such as images, stylesheets, and scripts. Allowing web content to be delivered quickly from the nearest edge server. This results in faster page load times and a better user experience.
• Securing Content Delivery: by offering security features
• Scaling Global Content Distribution: by enabling businesses to scale their content delivery globally, handling high volumes of traffic and providing consistent performance regardless of user location.
• Reducing Server Load: by distributing content requests across multiple servers, reducing the load on the origin server and preventing server overload during traffic spikes.
