- Basic public-facing website.
Additional features with Office 365 Dedicated Subscription Plans:
- Microsoft data center equipment that is dedicated to your company or organization and not shared with any other organization.
- Each customer environment resides in a physically separate network.
- Client communication across an IPSec-secured VPN or customer-owned private connection. Two-factor authentication is optional.
- ITAR-support plans.
- Ensure user workstations meet Office 365 client prerequisites.
- Implement the directory integration plan.
- Plan and implement internal and external DNS records and routing.

- Implement customizations, solutions, and apps for SharePoint Online.
- Monitor network availability and identify possible bottlenecks.
- Plan and design directory integration. Two options (either option can be deployed on premises or in Windows Azure): ＃Password sync (requires one 64-bit server). ＃ Single sign-on (requires ADFS and multiple servers).
- Ensure network capacity and availability through firewalls, proxy servers, gateways, and across WAN links.
- Acquire third-party SSL certificates to provide enterprise-security for Office 365 service offerings.
- Plan the tenant name, design site. collection architecture and governance.

Hybrid with Office 365 ( Combination of Office 365 + on-premise)
- 好处是有SharePoint Search , Business Connectivity, Duet Enterprise Online
- Users can see search results from both environments. Extranet users can log in remotely with an on-premises Active Directory account and use all available hybrid functionality

- From SharePoint Online: Users can perform read and write operations against an on-premises SAP system.
- Use Office 365 for external sharing and collaboration instead of setting up an extranet environment
- Move My Sites (Sky Drive Pro) to the cloud to make it easier for users to access their files remotely.
- Start new team sites in Office 365.
- Integrate an Office 365 site with on-premises BCS SharePoint environment.
