How quickly businesses move to make the data center more agile, application-oriented automation and virtualization of hardware and software infrastructure is becoming increasingly important.
Cisco Application Centric Infrastructure (ACI) provides the critical link between business-based requirements for applications and the infrastructure that supports them. The Citrix NetScaler Application Delivery Controller (ADC) combines infrastructure and applications and makes its configuration in the Cisco Application Policy Infrastructure Controller (APIC) through the integration.
Citrix NetScaler and Cisco data center enable ACI and cloud administrators holistically control L2-L7 network services in a uniform manner by the seamless insertion and automation of best-in-class NetScaler- Services built into the next generation of data centers on Cisco ACI architectures. A NetScaler ADC uses the Cisco Application Policy Infrastructure Controller (APIC) programmatically network deployment and management based on application requirements and guidelines for both data centers and enterprise environments.
conditions to apply Centric Vision
automateCisco APIC deals with the two most important requirements for achieving the application centric data center vision:
- policy-based automation framework
- Policy-based service charging technology
- Policy-based automation framework
The APIC allows application-centric as the creation of application profiles, the layer 4 to 7 services that define consumed by a particular data center-tenant application. A NetScaler ADC provides L4-L7 services such as load balancing, application acceleration and application security.
Integration between Cisco APIC controller and the NetScaler ADC is achieved through a NetScaler appliance package. Imported by APIC controller, the device package enables REST-based API integration and enables the APIC Controller detailed feature-level configuration of NetScaler perform.
ACI Enables policy-based service-insertion
Cisco APIC solution automates the steps routing of network traffic to the correct services on the basis of application policies. L4-L7 resources can be dynamically provisioned and configured on the application requirements on a per tenant basis.
Cisco APIC provides APIs or a graphical drag-and-drop interface for easy creation of L4-L7 services diagrams that indicate the network traffic routing. Each of the L4-L7 ADC functions that can be included in a service graph definition in the NetScaler appliance package, so that comprehensive NetScaler integration with the Cisco APIC. Policy-based service automates the steps inserting routing network traffic to the correct services such as application guidelines set. Automatic adding, removing and reordering of services allows administrators to quickly assign the resources for an application to change without displacing the need to program and reconfigure the network or the services.
For example, if a company decides to use the load-balancing function of a modern ADC allows administrators to easily define policies for services new to be used for the corresponding applications. The Cisco APIC can dynamically distribute new guidelines for infrastructure and service nodes in minutes without any manual changes to the network.
Once created in a data center to an application profile and contractually assigned, a service graph tenants and thus the definition of network traffic flow for each application and tenants.
benefits of using Citrix NetScaler ADCs in Cisco ACI
The unique Cisco ACI and Citrix NetScaler joint solution improves operations data center and deploy applications, the Cisco APIC as a central political control and management station directing and Cisco ACI service insertion technology traffic to the appropriate service ~~ POS = TRUNC
the main advantages are :.
The central point of the network controller with ADC service policy coordination and automation: The Cisco APIC acts as a point of configuration management and automation for NetScaler ADC (both MPX appliances and VPX virtual appliances), closely coordinated the ADC service delivery with the network automation and provides end-to-end telemetry and visibility of service-enabled applications and tenant
Scalable and resilient architecture for NetScaler ADCs. Cisco ACI defines a policy-based service insertion mechanism for both physical and virtual ADC appliances, full lifecycle service management based on workload instantiation and decommissioning provision
Investment protection: .. Cisco ACI and Cisco APIC are fully compatible with existing ADC networks to obtain models existing service operation and open standards protocols
