Performance Assurance for Cloud Applications

  1. 1. © 2016 ADVA Optical Networking. All rights reserved.1 Performance Assurance for Cloud Applications Wednesday, September 28, 2016
  2. 2. © 2016 ADVA Optical Networking. All rights reserved.2 The Cloud Is Great – How Do You Get There? … and are there any guardrails?
  3. 3. © 2016 ADVA Optical Networking. All rights reserved.3 Cloud Computing Today – YGWYG* Today, connections to the cloud are usually over the public internet Internet Cloud Datacenter Enterprise Enterprise Performance is not assured. *You get what you get!
  4. 4. © 2016 ADVA Optical Networking. All rights reserved.4 Internet Cloud Datacenter Enterprise Enterprise What Happens When There’s Trouble? Where’s the problem? Where’s the problem? Who do you call? Is it here? Maybe here? Could be here? Possibly in here?
  5. 5. © 2016 ADVA Optical Networking. All rights reserved.5 Internet Cloud Datacenter Enterprise Enterprise Assuring Access There are plenty of tools for assuring access to a data center Only the connectivity portion is assured – not the apps in the cloud EAD EAD EAD Access assurance for DIA Assurance for private line to cloud EAD
  6. 6. © 2016 ADVA Optical Networking. All rights reserved.6 What’s Missing? The Stuff Inside the DC … and there’s a lot of plumbing and machinery there AssuredOpaque EADEAD … and the cloud and connect are owned by different providers Enterprise
  7. 7. © 2016 ADVA Optical Networking. All rights reserved.7 Typical Cloud-Based Service • The path through the data center is not assured! (No guardrails) • The data center and connectivity are owned by different SPs Even if you wanted to do HW assurance in the DC, where would you place an EAD? Enterprise Data Center Per-server VMs, vSwitch and hypervisor
  8. 8. © 2016 ADVA Optical Networking. All rights reserved.8 Enterprise Data Center Per-server VMs, vSwitch and hypervisor Option 1: Add a soft probe on each server • Blue: data path • Red: test path Path is assured to a VM parallel to the user VM
  9. 9. © 2016 ADVA Optical Networking. All rights reserved.9 Enterprise Data Center Per-server VMs, vSwitch and hypervisor Option 2: Add probe to vSwitch • Blue: data path • Red: test path Path is assured to the base of the user VM
  10. 10. © 2016 ADVA Optical Networking. All rights reserved.10 Summary of Benefits Soft Probe vSwitch Probe End-to-end assurance Yes Yes Layer 2 and 3 Yes Yes Runs in existing IaaS Yes No – Requires update of vSwitch Assures all VMs on server No Yes No incremental VM No Yes
  11. 11. © 2016 ADVA Optical Networking. All rights reserved.11 Conclusions • Assured access is critical for public cloud applications – we need guardrails! • Assurance within the data center requires software-centric solutions – hardware probes won’t work • Probes and instrumented virtual switches are two viable options that are available today 11
