Reaching for Cloud Ethernet -

Boon or Bane for Cloud OperatorsSanta Clara, CA USAForum 1B: Ethernet in Data Centers - on Wednesday, April 30, 2014 from 8:30 to 10:50 am - Jathin Ullal, Marketing Manager, HP

Why Cloud Ethernet Adoption?

Santa Clara, CA USAApril 30, 2014 2

• Ethernet – primary building block for cloud networks

• Virtualization• Automation• Scalability• Programmability• Analytics:

BENEFITS:• Cost effectiveness• Interoperability• Automation• Programmability

CHALLENGES• Measurement• Relationship• Multi-vendors• Availability

Network Automation Challenge #1 Measurement

Santa Clara, CA USAApril 30,2014 3

You cannot manage what you cannot measure

• Are you able to provide overview reports by specific business units, customers, departments, or sites?

• Can you provide business visibility with high-level executive reports?• Do you have visibility into traffic-flow utilization by application type and availability?• Do you have the forecasting and trending data needed to proactively identify

problems?• Can you measure utilization of your network infrastructure across your users to

drive efficiency?

Network Automation Challenge #2 Relationships


Relationship between applications and their underlying components

• Can you maintain an up-to-date network topology?

• Can you view the impact of the cloud on your existing network topology maps?

• Can you capture and report historical topology and event changes for forensics?

Network Automation Challenge #3 Multivendor


Hardware, Software, Services from multiple vendors

• Can you manage physical and virtual network devices using one console?

• Can you manage multiple vendors using one console?

• Do you have visibility into the network of your SaaS provider?

Network Automation Challenge #4 Availability


Network reachability, availability and performance guarantee

• Are you able to proactively simulate and model effects on network due to network problems, outages?

• Can you guarantee network performance?

• Are you able to monitor application traffic to and from consumers of cloud services, even as devices are dynamically provisioned or retired?

• Can you guarantee service delivery levels by proactively managingand fixing network performance degradation?

Benefits & Challenges for the Enterprise

Disaster recovery

Benefits & Challenges for Providers

Santa Clara, CA USAApril-May 2014 8

BENEFITS:• Increased resiliency, assurance• Ease of scalability• Affordable price-point• Wide availability• Ubiquitous• Increased flexibility

CHALLENGES:• Consistent security and policy enforcement• Security breaches and privacy• L2 scale, VM migration• Compatibility, complexity• Slow network provisioning• Rigid billing models• No bandwidth guarantees

Network Functions Virtualization (NFV)


BENEFITS:• High-touch network appliances: fw, lb turned to VMs• Consolidates on industry standard x86 HW• Allows service chaining and elasticity• NFV complements SDN but not dependent• Allows lower cost usage based business models• Improves agility and provisioning

CHALLENGES:• HW & SW tuning affects performance• Scalability and performance varies• Difficult to benchmark performance and protect QoS, QoE and SLA

Software Defined Networking (SDN)


BENEFITS:• Enables faster configuration as well as automated reconfiguration of the network• More granular control over bandwidth-on-demand, QoS, traffic/path engineering• Enables pay-per-use network features• Consolidates control of multi-vendor environments• Faster implementation of reliability and security policies • Tomorrow’s elastic networks

CHALLENGES:• Centralization• Packet punting to controller• Security and scalability due to central controller• Forwarding protocol

Openflow


BENEFITS:• Protocol designed to manage multi-network vendors• Faster implementation of security & reliability policies• Granular control on QoS & traffic engineering

CHALLENGES:• Security & scalability• Forwarding protocol• Centralization• Packet forwarding

Cloud Orchestration Framework


End-to-end provisioning provided across virtual & physical infrastructure of data centers.

BENEFITS:• Self-service• Rapid provisioning• Optimize virtual resource usage

CHALLENGES:• Complex• Deployment challenging• Coordination on protocol neutral models and APIs

Cloud service provisioning use cases


• Enterprise - automated workflows and easier provisioning• Cloud operators for multi-tenant environments• Amazon - sell physical & digital goods• Big Data analytics• On-demand storage• Web billing services• Service chaining: Configuring L4-7 chain of NFV functions dynamically• Traffic engineering for global WAN interconnecting data centers• Dynamic exchanges: Create instant exchanges between peering networks• Big Data cut-through: Allow large data flows to bypass bottlenecks• Bandwidth on demand: Programmatic interface for end-user to request instant BW• End-to-end service provisioning: SP datacenter all the way to mobile handsets with QoS,

SLA
