IT Architecture and Techonology

1. Cloud Computing

   • Disruptive technological change
     • Changes in systems'
       • Design
       • Implementation
       • Maintenance
       • Operation
   • New capabilities
     • Traditional IT processes will run with new tools
   • Cloud containers can help architecting solutions

2. Organizations moving to the cloud

   • Different approaches
     • Greenfield
       • Building from scratch
     • Brownfield
       • Rearchitecture
     • Lift and shift
       • Unchanging and maintaning original design
   • Alternative
     • IBM Bluemix Local Platform
       • Uses a PaaS, allows the data to remain within the installation and with protection from firewalls

3. Attributes of an application based on the cloud

   • Horizontal and vertical scalability, upwards and also downwards
   • Oriented to temporary and non-fixed resources
   • Extensively automating processes
   • Achieve a loose coupling of services
   • Stop guessing the capacity required for the applications
   • Testing applications the most approximate to their actual scale of production
   • Evolutionary system architectures

4. XaaS environments

   • Evolving
     • New services will appear to improve existing ones
       • Identify functionality that can improve or restructure current solutions
         • Cognizant Cloud360 and CSC Agility Platform
           • Helps managing the complex environment generated by heterogeneous environments integrating it
