Bringing Mission and Performance Critical Applications to CloudStack
Sam Bercovici, Director Cloud Integration
What we want to discuss
• Load Balancing Models in the Cloud
• Radware’s LBaaS Solution Architecture and Workflow
• LBaaS Solution Comparison
• Operations Capabilities
Leadership in Application Delivery
Radware is one of the ADC market leaders and the most innovative vendor:• Cloud• Virtualization• SDN• NFV

Tenant Operated load balancing
• Tenant, insatiate a new load balancer VMs– Public Catalog / Market Place– Image uploading into the cloud
• The VM license can be bought directly from ADC vendor (BYOL) or cloud provider
• Billing / Licensing models– Perpetual– Periodic
• VM is managed by tenant.
Slide 5
Virtual Application Delivery Infrastructure (VADI)
• Unprecedented Consolidation
• Rapid & flexible Application Rollout
• Anywhere & everywhere HA
• Operational Simplicity

Slide 6
Load balancing as a Service
• Tenant, configures/operates logical load balancer capabilities via UI / API – Application driven
• Billing / Licensing models– Per-use– Periodic
• Back-end solution managed by cloud operator / service provider

Load balancing in Cloud Stack
• Are you using/providing load balancing capabilities in/with cloud stack hosted applications?
• Are you using/providing Cloud Stack LBaaS?
• Are you or your tenant using self-managed load balancing?
• What are the use cases (ex: dev&test, production, etc.)?

Radware’s LBaaS Solution Architecture and Workflow
Our customers tell us they want:
Service Level Assurance for applications
provide guaranteed SLA and isolation
Migrate existing applications to cloud
be feature compliant (SSL, L7, etc.) with legacy enterprise Load Balancers
Use network virtualization
interoperate with overlay networks and bypass its inherit performance bottlenecks
Multi site application deployments
provide GSLB and hybrid-cloud interoperability
