Citrix ADC overview
The Citrix ADC product line optimizes delivery of applications over the Internet and private networks. Citrix ADC is an application delivery controller (ADC) that accelerates application performance, enhances application availability with advanced L4-7 load balancing, secures mission-critical apps from attacks and lowers server expenses by offloading computationally intensive tasks. All these capabilities are combined into a single, integrated appliance for increased productivity, with lower overall total cost of ownership.
Citrix ADC is deployed in front of web, application and database servers. It combines high-speed L4-7 load balancing and content switching with application acceleration, data compression, static and dynamic content caching, SSL acceleration, network optimization, application performance monitoring application visibility and robust application security via an application firewall.
Citrix ADC appliances are installed in the data center and route all connections to back-end servers. The Citrix ADC features are enabled and the policies configured are then applied to incoming and outgoing traffic. Citrix ADC requires no additional client or server-side software, and can be configured using the Citrix ADC web-based GUI, RESTful API (“Nitro”) and CLI configuration utilities.
Citrix ADC is available as a high-performance network appliance and a virtual appliance for maximum deployment flexibility. The hardware based MPX appliances with multi-core processor designs are available with a wide range of appliance availability; from sub gigabit throughput to 50 Gbps. Each leverages a fully hardened and secure operating system.
Citrix ADC appliances provide multi-dimensional scalability for a superior ROI. Pay-As-You-Grow and Burst Pack upgrade licenses enable specific models to be upgraded to higher-end models within a particular platform via a software license. Citrix Networking SDX models allow up to 40 fully independently managed Citrix ADC instances to run on a single platform. Citrix ADC with TriScale clustering allows up to 32 Citrix ADC appliances (of the same platform, model and edition) to be aggregated into a single group to increase aggregate app delivery capacity.
