Office 365 is complex and the decision to move to Office 365 requires careful consideration of licensing, infrastructure, and your use of key applications.
- SharePoint and Exchange are the key value applications within the Office 365 suite. The need for upgrades to these applications should guide your Office 365 decision.
- The long-term cost savings are based on reduced server licences and storage. Most organizations will need to rationalize their infrastructure roadmap prior to Office 365.
- Concerns over security on the Office 365 platform are largely over-blown; Microsoft complies with EU safe harbor, FISMA, and HIPAA legislation.
Your Office 365 roadmap should be decided based on the Office productivity suite. Define your content usage by department to minimize unnecessary spend on bloated licensing.
