ADC in the Virtualized Data Center
Slide 45Slide 45
Virtual Data Center Requirements from an ADC
1. Flexibility to support new virtualized network topologies
2. Align ADC with data center ‘moving parts’ changes
3. Instant provisioning of ADC
4. Ensure complete ADC privacy and segregation
5. Accommodate applications with different SLA, performance predictability and resilience needs
6. Simple ADC manageability
7. Participate in orchestration ecosystem

Integration to Ecosystem
VADI Services
V A D I ™
• Reduce ADC CAPEX and OPEX through real ADC consolidation and virtualization
• Full DC virtualization agility across the application delivery layer• Accommodate any application: SLA, performance predictability and
resilience needs• Reduce P2V risks and enable smooth migration• Enable integration of ADC services into the virtual DC through open API
• In the virtual data center Application Delivery Controllers are transformed into virtual ADC instances (vADCs)
• Each vADC can run on top of a specialized and general purpose computing resource
• Each vADC provides a consistent set of basic and advanced application delivery features and services, regardless of the computing resources it utilizes:
• SLB
• Global SLB
• Application acceleration
• Integrated security
• BWM• Etc.
Transforming the ADCs into application delivery services
Virtual ADC Instances (vADC)
Slide 48Slide 48
ADC Computing Resources in the Virtualized Data Center
Dedicated ADC
• Dedicated physical ADC device running a single vADC - “Siloed” data center architecture
- Hybrid (virtualized and physical) data center
- Applications requiring high performance predictability
Radware ADC-VX
• ADC hypervisor running multiple vADCs on a specialized ADC hardware
- ADC consolidation projects
- Virtualized data center requiring high ADC agility
- Applications requiring high performance predictability
Radware Soft ADC
• vADC on a general server virtualization infrastructure- Cloud providers & virtualized data center requiring high ADC agility- Development, testing and QA environments- Applications requiring only best-effort performance
Slide 49
Why are 3 form factors required?
• Application SLA requirements
• Number of required vADC instances
• Throughput capacity each vADC requires
• Cost savings objectives
• Data center footprint limitations
• Application deployment model
Integration to Virtual Data Center Ecosystem
Orchestration System Integration
• Orchestration systems provide - End-to-end management of mission-critical applications and services - Work flows which can provision a new service based on business events
• All 3 ADC form factors are fully integrated with the virtual data center ecosystem’s orchestration system through dedicated plug-ins and APIs
• Allows IT manager to incorporate Radware’s ADCs into the virtual data center workflow automation
• Enables integration to both standard and home grown virtual data center automation and provisioning systems
• First orchestration system to be integrated is VMware vCenter Orchestrator
Unleashing the full agility of complete application services
and end-to-end service creation Slide 50
Unique VADI Services
Provisioning and Decommissioning
• vADCs are instantly provisioned and/or decommissioned through ADC management system or orchestration systems’ API
- Eliminates the need for manual provisioning and reduces IT OPEX- Improves IT responsiveness to business needs
• Dynamic resource allocation - Automatically allocate more resources to a vADC, when vADC resources are maximized
- Improves service levels for all applications- Ensures each vADC has sufficient resources at any point in time- Ensures the correct distribution of resources across VADI
• vADC Migration - easily move a vADC instance between different form factors
- Simplifies ADC P2V migration- Streamlines the deployment of new applications and services through
simple migration of a vADC instance from testing to production- Enables scheduling ADC maintenance with zero downtime
