------------------------------------
Planning and Managing Azure Cost:
-Azure purchases
--Enterprise agreement
-Resellers
--Partners
--Pay As you go

Factor affecting cost:
  • -Usage meters
  • -Resource Type
  • -Subscription Type
  • -Location

Use TCO Calculator
-Define your workload
-Adjust assumption

Minimizing your Cost:
  • -Monitor usage
  • -Use spending limit

Cloud Computing in simple

-
Cloud Computing =   Infrastructure as a Service (IaaS) + Platform as a Service (PaaS) + Software as a Service (SaaS) Cloud computing, also known as Cloud Technology, Cloud Applications or Cloud-based services. Cloud Computing is the practice of using a network of remote servers hosted on the internet to store, manage and process data, rather than a local server or a personal computer. Examples of cloud-based services include customer self-scheduling, data storage, online payment, and accounting software Different Type of Clouds Infrastructure as a Service (IaaS)  – Allows users with the services like Virtual servers, Virtual storage, Physical Database, Virtual Network, Physical Network. E.g. Google Storage ,  IBM Cloud Computing ,  Nimbus Platform as a Service (PaaS)  – Provides computational resources via a platform upon which applications and services can be developed and hosted. E.g. Databases, Data Stores,  Force.com ,  Google App Engine ,...
