Agenda

3. From IDC, July 2013
The Cloud Opportunity: Global
Momentum Takes Hold
Public IT cloud services spending will reach $98 billion in
2016, with a compound annual growth rate (CAGR 2011-
2016) five (5) times the growth of the IT industry
overall.
Early-stage companies (less than five years in business) are the
most eager buyers of cloud, concerned with start-up capital
costs and less likely to build and staff a conventional
datacenter, and plan to increase their spend on public cloud by
24% over the next few years.

datacenters
Basic Azure Terminology
Platform as a Service (PaaS)
Services platform for applications with low infrastructure
maintenance. Lowers administration and provides easily
scalable environment for websites and services. No need
to worry about patching, backing up, HA, etc.
Infrastructure as a Service (IaaS)
VMs on demand created from available images and
requiring same administration as on premise virtual
infrastructure. Gives greater flexibility.
