Salesforce began as a customer relationship management software and has grown into a cloud computing platform. It provides software as a service and platform as a service, including applications like Sales Cloud, Service Cloud, and Force.com for building custom applications. Salesforce uses a multi-tenant architecture allowing multiple customers to use a single instance of the software. It includes tools like Visualforce for customizing interfaces and Apex for adding business logic through code.

2. Introduction
•Salesforce is originally a Customer Relationship
Management (CRM) software.
•CRM is originally software for managing customer
interaction, such as scheduling tasks, emailing,
texting, and many more tasks.
•Salesforce grew into a cloud software solution and
acquired several other companies for Paas and
Saas.

4. Platform as a Service
Platform as a service (PaaS) is a category of cloud
computing services that provides a computing
platform and a solution stack as a service. The
provider provides the networks, servers, storage,
and other services that are required to host the
consumer's application

5. Software as a Service
Software as a service (SaaS) is a software
distribution model in which applications are hosted
by a vendor or service provider and made available
to customers over a network, typically the Internet.

6. Subscription

7. Introducing Force.com
lForce.com is a cloud computing platform as a
service system from Salesforce.com,that
developers use to build multitenant applications
hosted on their servers as a service.
lSalesforce.com is the Sales Cloud for ready-to-use
products for CRM.
lForce.com does not expose the underlying
infrastructure.

8. Multi-tenancy
Multi-tenancy refers to a principle in software
architecture where a single instance of the
software runs on a server, serving multiple client-
organizations (tenants). Multitenancy contrasts
with multi-instance architectures where separate
software instances (or hardware systems) operate
on behalf of different client organizations.

9. SalesForce Pieces

10. Chatter
Chatter is a brand-new way to collaborate at work.
Because status information about people and
important projects is automatically pushed to you,
Chatter makes it easy to connect with the people
and information you care about most.

12. Typical 3-tier Architecture
(Microsoft)

13. Salesforce
Salesforce is also 3-tier, but many of the internals are
handled through abstraction. There are:
1) Out-of-box interfaces, which include security,
dashboards, workflow, and user interfaces. Coding is
optional.
2) VisualForce is an editor for customization of User
Interfaces if not out-of-box.
3) Apex, using the developer console, is for writing code to
the Salesforce API, for example a SOAP or batch
application for importing custom data.

14. VisualForce
Visualforce is a framework that allows developers
to build sophisticated, custom user interfaces that
can be hosted natively on the Force.com platform.
The Visualforce framework includes a tag-based
markup language, similar to HTML, and a set of
server-side “standard controllers” that make basic
database operations, such as queries and saves,
very simple to perform.

15. VisualForce -MVC
The Model-View-Controller is the most common
design in Software Architecture.

16. VisualForce - Example

17. Apex
Apex is a strongly typed, object-oriented
programming language that allows developers to
execute flow and transaction control statements on
the Force.com platform server in conjunction with
calls to the Force.com API. Using syntax that looks
like Java and acts like database stored procedures,
Apex enables developers to add business logic.

19. AppExchange
Launched in 2005, AppExchange is a marketplace
for cloud computing Web application built for the
Salesforce.com community.
Some modules are free and some require a license
fee.
Examples of modules are Google Mail and Android
connectors.
