The EDOS program is ideal for large enterprises and government organizations with more than 5,000 users. An EA allows customers to subscribe to Microsoft online services such as Microsoft Exchange Online, SharePoint Online, and Lync Online. The services do not have to be licensed throughout the company, but can be reserved in addition for each user. The licensed customer is either the Standard Edition or the Enterprise Edition of each service. The duration of EDOS is three years and is linked to an EA. When signing the contract, the customer must define and communicate the number of desktop computers or qualified users and the desired Microsoft Enterprise or Enterprise Online Services products. This information is the first purchase. EA and EAP customers with active agreements on this date may continue to acquire new licenses until the end of their current term. Alternatively, the customer can sign an enterprise online service agreement with Microsoft. This option does not require enterprise-wide standardization. The customer must acquire at least 500 licenses of enterprise online services. Can`t this EA customer just use their SQL Server Enterprise Server CAL licenses? That`s a good question! Let`s see what the SQL Server 2012 licensing rules indicate for this customer: the annual cost of participating in the Microsoft Enterprise Agreement program per 1 PC is the basis for forecasting the cost of Office software technologies for the next 3 years, given that the cost of a Microsoft license for 1 PC is set at the time of signing the contract.
