Dell’Oro Group’s Application Delivery, Security & Edge Services research tracks how applications are delivered, distributed, protected, and increasingly executed across data centers, clouds, and provider-operated edge platforms. The service analyzes technology transitions, vendor positioning, customer-vertical trends, and regional market dynamics across Application Delivery Controllers (ADC), Content Delivery Networks (CDN), DDoS Protection, Web Application and API Protection (WAAP), and Application Edge Compute.
Applications are no longer delivered through a single data-center front door. Traffic increasingly traverses distributed delivery networks, application security services, load-balancing infrastructure, and provider-operated edge platforms before reaching application infrastructure. At the same time, programmable edge platforms are moving selected application logic closer to users, devices, APIs, and application ingress.
The research separates these adjacent functions according to their primary purchase driver and first-order value proposition. Application Delivery and Distribution covers ADC and CDN. Application Security & Resilience covers DDoS Protection and WAAP, with WAAP further segmented into API Protection, Botnet and Abuse Management, and Core Web Application Firewall (WAF). Application Edge Services covers Application Edge Compute, including qualifying AI inference workloads delivered through distributed provider-operated edge platforms.
The research also analyzes form-factor transitions across physical, virtual, and SaaS delivery models where applicable. Worldwide customer-vertical segmentation for CDN and WAAP provides an additional view of how demand differs across industries and customer types.
Convergence at the application edge is making traditional market boundaries harder to interpret. CDN providers are adding security and programmable execution. WAAP platforms are expanding beyond traditional WAFs to include API protection and bot and abuse management. ADC platforms increasingly integrate adjacent security functions, while application-edge platforms can support distributed application processing and AI inference.
These adjacencies do not make the underlying markets interchangeable. Separating application delivery, security, resilience, and edge execution helps vendors, service providers, and investors analyze where spending is moving without double-counting bundled capabilities or assuming that every new feature represents a new revenue pool.
AI adds another dimension. Inference can benefit from execution closer to users and application ingress, but AI infrastructure does not automatically qualify as Application Edge Compute. The architecture, operating model, and primary purchase objective remain central to market classification. Customer-vertical segmentation similarly helps distinguish broad market growth from industries where application delivery and application protection requirements are changing most rapidly.
