Conclusions

– Standardization at the IaaS level will be a long hard road

– Public cloud offerings are improving wrt Security and Private Public interconnect

– Put compute close to the data

9

– Put compute close to the data• Networking can help

– SaaS + SLA’s at the service level may well be the easier path for hybrid cloud

Thank You.
