Hi Pavan,

What is Community Cloud?

Salesforce Community Cloud is an online collaboration and business process platform that connects employees, customers, partners, suppliers, and distributors. Organizations can create fully branded public or private communities that connect members directly with one another — and with relevant content, data, and business processes. Community Cloud is the only community platform that combines the power of social with mobile participation, trusted security, fast deployment, and a direct connection to business processes.

Why did we create Community Cloud?

Today’s customer expects to interact with their vendors, share experiences with other customers, and find the information they need from any mobile device. To meet these expectations, companies need to deepen customer and brand relationships, understand rapidly changing customer needs, and connect customers directly to their business processes. Community Cloud was built to address all of these needs.

Community Cloud goes beyond portals by adding social collaboration, extensive branding, customization, and mobile access, while retaining enterprise security and tight integration with business processes.

What types of communities does Salesforce support?

Salesforce provides three types of communities that can be used for a broad variety of purposes; from customer service to marketing or engagement of resellers, suppliers, agencies, and partners.

Customer Communities deliver rich collaboration, mobile access, and consistent branding for even the largest groups. For example, a service community enables customers to answer questions for other customers, quickly find the information they need, or work with service reps to resolve issues — decreasing time to resolution while increasing engagement and loyalty.

Partner Communities provide even greater ties to business processes along with the added power of role-based security to segment the data that’s been shared with different members. For example, partner communities enable companies
to manage reseller relationships by keeping some lead and funding information private, but enabling collaborative selling between partners, leading to more engaged partners and increased deal flow. Great for agency, vendor, and extended sales team effectiveness.

Employee Communities deliver on the promise of doing business from anywhere and any device. Employees can collaborate, share files, get information that is most relevant to them, and is connected to business process for improved productivity.

What are the key features of Community Cloud?

No other community platform offers the same combination of capabilities along with deep integration into business processes.

Key Community Cloud features include:

• Business Process Integration. Members can create and collaborate on support cases, sales opportunities, or campaigns from within the community.

• Social Collaboration. Members can interact, collaborate on goals, and form groups to support their interests.
