Expectations within Enterprise Cloud

“Always On” expectation – costs of downtime has

skyrocketed and business SLAs has had to rise to keep

pace

Rise in data center “Operational Complexity” – with

virtualization, multi-tier applications, and heterogeneous

platform environments i.e. IT managers are struggling to

get arms around the problem!

“Do more with Less” – tight resource constraints that

hold IT budgets and headcount flat

Self-Service ‘Cloud Computing’ where resources are

provisioned and available almost instantly

Existing Enterprise Network Is Too

Expensive to Scale

“OpenFlow has helped us improve backbone performance and reduce backbone complexity and

cost.” Urs Hoelzle, Google (Google Fellow, SVP Technical Infrastructure)

<1 year: 3x more ports in 3x less space and 2.5x less power (absolute terms: 9x density & 7.5x power)

2 years: 3x less space 2.5x less power same density

Cap Ex savings

‣ No need for proprietary protocols or network elements/management tools to provide automated device provisioning

Op Ex savings

‣ Provisioning a new rack simply involves racking/stacking the devices and cabling them up, no network configuration necessary – saves hours/money on network provisioning

‣ Device failure doesn’t require on-site network-admin skill/time (money) to reconfigure failed network element / serial console cable – improved MTTR, cost savings

Zero Touch Provisioning (ZTP) & Recovery (ZTR)

‣ Auto-provision switch on first and every start-up

‣ Full customization using open standard tools

‣ Graceful insertion of new hardware

‣ Automation and parallelization of repetitive tasks

‣ Greatly reduce chances of human error

‣ Reduce maintenance window duration

‣ Enables Zero Touch Replacement

‣ Reduces on-site skill requirement

‣ Especially useful in secure DC facilities

Microsoft Rollouts a Datacenter in Minutes http://www.nanog.org/meetings/nanog55/presentations/Monday/Lapukhov.pdf

Microsoft used SDN to simplify their

data center networking at the heart of

their online services (Bing, Azure, ..)

significantly improving the size/scope/flexibility

while reducing capex & opex.

Facebook: 1 technician for 15,000 servers http://www.wired.com/wiredenterprise/2012/06/facebook-nc-data-center/

“[..] the company is running its

entire network at 10 gigabits per

second. At the same time,

Facebook has overhauled the

topology of the network. Previously,

the company used what’s called a

‘layer 2’ network [..] This needed to

change when it realized that traffic

between its servers was growing so

quickly.”

“[..] the company still needs only a

single data center technician for

every 15,000 servers.”
