Introduction

To understand cloud platforms, it is useful to start by looking at cloud services in general.
Services in the cloud can be grouped into three broad categories. Those categories are:
Software as a service (SaaS): A SaaS application, also referred to as “on-demand software”
supplied by ISVs or “Application-Service-Providers” (ASPs), is a software delivery model in
which software and associated data are centrally hosted on the cloud. SaaS is typically accessed
by users using a thin client via a web browser. SaaS has become a common delivery model for
many business applications, including Office & Messaging software, DBMS software, Management
software, CAD software.
Attached services: Every on-premises application provides useful functions on its own. To enable
an event subscription to respond to events from your Enterprise Content Management server,
you need to create an attached service that can be used to invoke a Content UCA.
Cloud platform: It is a system where software applications may be run in an environment
composed of utility cloud services in a logically abstract environment. Platform as a Service is
a Cloud Platform offered by a service provider as a hosted service which facilitates the deployment
of software applications without the cost and complexity of acquiring and managing the
underlying hardware and software layers.

Example: Google AppEngine and Force.com.

7.1 Collaborating on Calendars Schedules and Task Management

As anyone in a large office knows, scheduling a meeting can be a frustrating experience.
Not only do you have to clear time from all the attendees’ individual schedules, you also have
to make sure that the right-sized meeting room is available at the designated time.
An online scheduling application is a solution to all your scheduling and task management
problems. This web-based application takes care of scheduling your meetings, for both large
and small groups. The typical application requires all users to enter their individual calendars
beforehand. When you schedule a meeting, this application checks attendees’ schedules for the
first available free time for all. The app then generates automated email messages to inform
attendees of the meeting request and the designated time, followed by automatic confirmation
emails when attendees accept the invitation.
