Looking back: 20 years of DC
• Network architecture: from campus architectures to leaf/spine and SDN
• Compute hardware: from dedicated HW to virtualized environments
• Storage (and Backup): from direct attached to SAN and SSD innovation
• Technical infrastructure
• Power: from <1 to 3.5kW+ per rack
• Cooling: airflow models, alternative cooling
• Structured cabling: copper is dead, all fibre ?
• Product & service offerings: from colo to managed IT solutions
• Operating models: from manual physical setup and in-life changes to spin-up within minutes and scale-out/in
• Next: Open Compute ?

Cloud Centric Networking (CCN) project
Current DC network challenges
• Logical Scale (VLANs, Tenant Networks)
• Stranded Capacity (Link waste, STP)
• Flexibility, Elasticity (complex dynamic connectivity)
• Port Density – limited 10Gbe
• Automation complexity
• TCO
Scalability (physical / logical)
Efficient resource utilisation
APIs
Gateway functionality Fabric integration
QoS
Multi tenancy
WAN integration
CMS/CRM integration
Redundancy
Security
Energy efficiency Open architecture

Compute HW, CRM, hypervisors and portals
• Web 2.0 companies vs Service Providers
• Compute hardware: which approach (e.g. blade server + fabric) ?
• Cloud Resource Managers
• Which one to pick ? How deeply interconnected is it with the external service offering ?
• How many make sense ?
• Hypervisors
• As above...
• Portals
• Customer experience (global or per go-to-market) ?

What’s next ?
• Closer linkage between the technical infrastructure and the cloud platforms
• Platform economics
• Start of a consolidation cycle ?
• Evolution of the operating model
• Where does devops work ?
• How much innovation can one absord each year ?
