The Cloud Is Great – How Do You Get There?

… and are there any guardrails?

Cloud Computing Today – YGWYG*

Today, connections to the cloud are usually over the public internet

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?

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

What’s Missing? The Stuff Inside the DC

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

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

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

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

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
