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
