In our last post, we discussed how growing workload demands in enterprise data centers requires a new approach to application delivery controllers (ADCs). Traditional appliance-based ADCs are slow and costly to implement, difficult to manage, and lack the flexibility and scalability needed in today’s dynamic data center environment. Software-based ADCs are less expensive because they can be deployed on commodity hardware but otherwise have the same drawbacks as the appliance-based approach.
Software-defined ADCs overcome these limitations. A centralized controller provides automated, policy-based management of a pool of ADCs that can be distributed across multiple environments. This not only streamlines administration, but makes it possible to scale ADC services up or down according to traffic levels.
The controller receives and analyzes a continuous stream of application telemetry data sent by the distributed ADCs. This enables the controller to automatically decide on service placement, autoscaling and high availability for each application. The control plane also monitors the “health” of the system and reacts to data plane component failures or any application changes.
Because the data plane elements are deployed on commodity hardware, they can be spun up or down dynamically wherever services are needed. Active-active high availability configurations can be set up at a fraction of the cost of traditional ADCs.
Software-defined ADCs can also provide advanced functionality, including:
The Avi Vantage software-defined ADC platform from Avi Networks provides software load balancing and an intelligent web application firewall in a centrally managed, elastic services fabric. It consists of three components:
The platform adapts to dynamic environments, empowering IT administrators with next-generation tools for multi-cloud traffic management. The Avi Controller auto-scales load balancing resources based upon thresholds, and the Avi Service Engine scales out horizontally on demand. Based upon REST APIs, Avi Vantage provides end-to-end visibility and integrates seamlessly with the continuous integration/continuous delivery pipeline for rapid application rollouts.
