Salesforce provides: Sales Cloud (lead management, opportunity tracking, forecasting), Service Cloud (case management, omnichannel, knowledge base), Marketing Cloud (email, journeys, personalization), and the Salesforce Platform (custom applications built on the metadata-driven architecture with Apex code, Lightning Web Components, and Flow automation). AppExchange provides 5,000+ pre-built solutions.
Enterprise Salesforce requires: multi-cloud architecture (Sales + Service + Marketing + MuleSoft integration), data model design (object relationships, record types, sharing rules), governor limit strategy (SOQL limits, CPU time, callout limits), and the DevOps practices (Salesforce DX, scratch orgs, CI/CD) that prevent org sprawl.
