Medianova provides content delivery, performance optimization, storage, and security services for websites, applications, APIs, and media workloads. This page introduces the core concepts and services referenced throughout the Medianova documentation. ### Key Services and Concepts #### CDN (Content Delivery Network) A Content Delivery Network (CDN) is a distributed network of edge servers that delivers content from locations closer to users. By serving content from a nearby Point of Presence (PoP), a CDN can reduce latency, improve response times, and reduce traffic to the origin server. #### Static Content Delivery Static Content Delivery accelerates cacheable assets such as images, CSS files, JavaScript, fonts, downloadable files, and other static resources. Medianova provides **Small CDN** and **Large CDN** resource types for static content delivery. These resource types support different content delivery workloads while reducing requests to the origin. **Related concepts** * [Small CDN](/products/performance-cdn/static-content-delivery/create-small-cdn-resource.md) * [Large CDN](/products/performance-cdn/static-content-delivery/create-large-cdn-resource.md) * [Static Content Delivery](/products/performance-cdn/static-content-delivery.md) #### Dynamic Content Caching Dynamic Content Caching accelerates websites, applications, and APIs whose responses are generated by the origin application. Medianova's **Dynamic CDN** optimizes request delivery and supports configurable caching policies for eligible dynamic responses. Caching eligible responses at the edge can reduce latency and origin load. **Related concepts** * [Dynamic CDN](/products/performance-cdn/dynamic-content-acceleration/create-dynamic-resource.md) * [API Caching](/products/performance-cdn/api-caching.md) * [Dynamic Content Acceleration](/products/performance-cdn/dynamic-content-acceleration.md) #### Video on Demand (VOD) Video on Demand (VOD) enables users to access pre-recorded video content on demand. Medianova supports VOD delivery using adaptive streaming technologies such as HLS and MPEG-DASH. Compatible video players can select an appropriate stream based on available bandwidth and playback conditions. **Related concepts** * [Video on Demand](/products/performance-cdn/static-content-delivery/create-vod-resource.md) #### Private CDN Private CDN provides dedicated content delivery infrastructure for organizations that require control over network architecture, security, capacity, or compliance requirements. Unlike shared CDN infrastructure, a Private CDN is deployed for a specific organization and can be configured according to its delivery requirements. **Related concepts** * [Private CDN](/products/performance-cdn/private-cdn.md) #### Image Optimization Image Optimization transforms JPG and PNG images delivered through Medianova CDN without modifying the source image at the origin. Supported URL-based processing operations include resizing, padding, cropping, rotation, watermarking, and custom cropping. Each transformed image URL is cached as a separate object. WebP and AVIF optimization are documented separately for deployments that use modern image formats. **Related concepts** * [Image Optimization](/products/performance-cdn/image-optimization-and-webp/image-optimization.md) * [WebP](/products/performance-cdn/image-optimization-and-webp/webp.md) * [WebP+](/products/performance-cdn/image-optimization-and-webp/webp+.md) * [AVIF](/products/performance-cdn/image-optimization-and-webp/avif-optimization.md) #### Stook Cloud Object Storage Stook is Medianova's S3-compatible cloud object storage service for storing and retrieving unstructured data. Stook can be used as an object storage platform or as the origin for supported CDN Resources. **Related concepts** * [Stook Object Storage](/products/object-storage-stook/stook-cloud-object-storage.md) #### SSL/TLS Encryption SSL/TLS protects data transmitted between clients and servers. Although the term SSL remains widely used, modern HTTPS connections use TLS. Medianova CDN uses SSL/TLS certificates to secure HTTPS connections between clients and CDN edge servers. Depending on the deployment, you can use a shared certificate, upload your own certificate, or request a Free SSL certificate. Communication between the CDN and the origin can also use HTTPS when origin SSL is enabled. **Related concepts** * [SSL Certificates](/products/security/ssl-tls-encryption.md) * [TLS/SSL](/products/security/ssl-tls-encryption.md) #### Web Application Firewall (WAF) A Web Application Firewall (WAF) inspects HTTP and HTTPS requests to identify and block malicious traffic before it reaches the origin application. Medianova WAF provides managed rule sets and configurable security policies for protecting web applications against application-layer threats, including SQL injection and cross-site scripting (XSS). **Related concepts** * [Web Application Firewall (WAF)](/products/security/web-application-firewall-waf.md) * [Page Rules](/products/performance-cdn/static-content-delivery/advanced-configuration/page-rules.md) * [Security](/products/security.md) #### DDoS Protection DDoS Protection mitigates distributed denial-of-service attacks by filtering malicious traffic before it reaches the protected origin. It can be used with other security controls, including Rate Limiting, WAF, IP filtering, and geoblocking. **Related concepts** * [DDoS Protection](/products/security/ddos-protection.md) * [Rate Limiting](/products/security/rate-limiting.md) * [Security](/products/security.md) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://clients.medianova.com/getting-started/concepts.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
