• why is the cloud the future for most organizations 
    • the cloud 
      • elastic leasing of pooled computer resources over the Internet 
    • elastic 
      • leased computing resources increased or decreased dynamically, programmatically, in a short span of time and organizations only pay for resources used 
    • flexibility to meet unpredictable demand while limiting financial risks 
  • pooled 
    • cloud resources are pooled 
      • many different organizations share same physical hardware through virtualization 
      • benefit from economics of scale 
        • average cost production decreases as size of operation increases 
      • major cloud vendors 
  • why is the cloud preferred to in-house hosting 
    • control of data location 
    • small capital requirements 
    • in depth viability of security and disaster procedures 
    • in depth viability of security and disaster preparedness
    • no obsolescence
    • industry-wide economics of scale;hence cheaper 
    • known cost structure 
    • its cheaper and less hassle
    • control over your data   
  • why now?
    • been around since 1960's 
      • time sharing vendors provided slices of computer time on a use-fee basis. 
    • factors that made cloud-based hosting advantagous 
      • cheap processors, data communication, and data storage are nearly free 
      • virtualization technology enables near instantaneous creation of a new virtual machine 
  • when does the cloud not make sense 
    • when by law or by standard industry practice 
  • how do organizations use the cloud 
    • SaaS ( software as a service) - salesforce.com,google grid,  
    • Paas ( platform as a service) 
    • IaaS ( infrastructure as a service) 
  • using a private cloud 
    • private cloud 
      • owned and operated by an organization for its own benefit 
      • creates private internet and designs applications using web services standards 
  • what does the cloud mean for your future 
    • fewer organizations will set up their own computing infrastructure 
    • readily obtain elastic resources at very low cost 
    • more small tech startup business
    • new categories of work 
      • remote action systems, telediagnosis, telesurgery, telelaw enforcment 
    • value of top notch performers increase
