Cloud computing or disguised Application Service Provider?

use of computing resources delivered as a Service over a network

33


Infrastructure as a Service (IaaS)


34

¨  …to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software…

¨  …consumer DOES NOT manage or control the underlying cloud infrastructure but has control over [it]…

¨  … possibly limited control of select networking components (e.g., host firewalls)

35

¨  …to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider

¨  … The consumer DOES NOT manage or control the underlying cloud infrastructure…

¨  … [but consumer] but has control over the deployed applications and possibly application hosting environment configurations

Software-as-a-Service (SaaS)


36

¨  …to use the provider’s applications running on a cloud infrastructure…

¨  The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail)

¨  The consumer DOES NOT manage or control the underlying cloud infrastructure … with the possible exception of limited user-specific application configuration settings

¤  safaribooksonline.com ¤  books24x7.com ¤  getabstract.com

Tips


61

¨  Develop a mindset, adapt to change, work in team ¨  Speak like a business man, code like a geek ¨  Put in place an Escrow, Backup strategy & Source

Control first ¨  Do not set the “automatic updates” ¨  Document briefly your code but extensively your

architecture and processes ¨  Focus on innovation and how to bring value to the

business using your IT knowledge

Tips


62

¨  Integration projects are key ¨  Be bold in technologies applicable in multiple

domains ¨  Don’t try to become a project manager nor a

business analyst (it’s boring) ¨  Facilitate the life of your users, they are always

right!

Project manager


63

¨  Run Forest, Run! (after the others) ¨  Value and report on Risk, EAC, ETC, Actuals, delays,

changes ¨  Learn what is important for the business (P&L)
