Rainy Days ahead: Is the Cloud Ready for Cloud?

744 Aufrufe

Veröffentlicht am

All cloud computing initiatives have one thing in common – data is centralized, while users are distributed. This places an increased emphasis on the network, making cloud computing susceptible to the same WAN bandwidth, latency, and quality challenges that impact other enterprise applications. This session will discuss how WAN challenges impact the performance of critical cloud applications, and how they can be overcome using common WAN optimization techniques.

Rainy Days ahead: Is the Cloud Ready for Cloud?

  1. 1. Is the Cloud Ready for Cloud? Joe Bombagi Technical Director EMEAStrictly Confidential jbombagi@silver-peak.comDo Not Distributeor Reproduce
  2. 2. Big Plans in IT = Increased Network Dependency• Disaster recovery  Protect more data across longer distances over converged networks• Data center consolidation / cloud  Data and server placement impacted by WAN performance• Server and storage centralization  Users farther from resources• Real-time collaboration  Improve quality of unified communications (voice/video)• Virtualization  Multisite VDI and VM migration impacted by poor WAN quality Strictly Confidential © 2011 Silver Peak Systems Inc 1
  3. 3. All Cloud Services Have Same Challenges…• Users farther away from centralized resources• Mix of protocols (TCP, UDP, HTTP(s), …)• Encryption is a “must”• Data migration challenges• Who owns the link? (private vs. public) Source: Forrester (October 2009) Strictly Confidential © 2010 Silver Peak Systems Inc. 2
  4. 4. Let’s Not Forget the Network!!!Trends: WAN Capacity WAN Quality• Data volumes exploding • MPLS and cloud are shared• Bandwidth becoming cheaper • Convergence of voice, video, data and storage onto one network
  5. 5. Don’t let the network be the weak link in your cloud strategy
  6. 6. Network Optimization is Required for SuccessfulCloud DeploymentGlobal Management Latency  Loss  Bandwidth  System (GMS) VRX MPLS Internet Cloud NX Appliance VX Network Acceleration Network Integrity Network Memory™ Overcome Latency and - Traffic shaping / QoS Real-time deduplication protocol chattiness - Forward Error Correction (FEC) of ALL IP WAN traffic - Packet Order correction (POC) Strictly Confidential © 2011 Silver Peak Systems Inc 5
  7. 7. Best Practice Recommendations forDeploying WAN Optimization with Cloud• WAN optimisation must scale to support the cloud • LAN throughput, WAN throughout, and flows• Virtual appliances are critical … • Hardware independence – must work on all hypervisors; no hardware acceleration or encryption• Network Integrity features are a “must have” • Remember – we are talking about sending business critical traffic over the Internet!
  8. 8. Case Study:Google Optimizes Google Apps for EmployeesNetwork Background:•170 locations•Two 100 Mbps WAN connections to each location;•Network quality and security concerns (IP VPN and MPLS)•Heavy packet loss and latency (10 to 400 ms) on international locationsBusiness Challenges•Developers’ appetite for bandwidth resulting in runaway telco expenditures•Real-time collaboration – world’s largest user of videoconferencing•Network quality adversely impacting Google mail and other cloud services.Results:•WAN utilization reduced by 65% on average•Optimizing hundreds of thousands of simultaneous flows•Reduced packet loss; Eliminated out-of-order packet delivery•Secure transport using IPsec 7
  9. 9. Case Study: Autodesk Optimizes Hosted Email with 70 Critical ApplicationsNetwork Background•100 sites worldwide; 70 mission critical applications• Microsoft Exchange deployed as a 3rd party hosted cloud service•Packet loss on MPLS and IP VPNS•High latency to international offices•Bandwidth saturated every “build season”Business Challenges•Poor WAN performance routinely delayed product development•Internal network a “proving ground” for performance of company’s own applications•High cost of WAN bandwidthResults•Streamlined product development process•Reduced WAN bandwidth by 75 percent•Eliminated packet loss•Optimized all applications, including file, email (cloud), web, Aspera and AutoCAD
  10. 10. Case Study: Global Telco reduces Costs withOffsite Data ReplicationTechnical Challenges:•Very large OC-48 WAN links between data centers•20 ms to 100 ms latency between locations•Effective throughput limited to 22 Mbps when performing replication to hosted sites.Business Challenges•Missing Recovery Point Objectives (RPO)•Took several weeks to recover from major outageResults:•27x improvement in effective throughput•16x faster data transfer times•Data migrated to cloud in 3 days (instead of 3 weeks)
