Microsoft and Salesforce are reportedly looking to form a cloud partnership

Microsoft Corp. (MSFT) and Salesforce.com Inc. (CRM) are planning to announce an agreement as soon as today that will enable customers of Microsoft’s cloud-computing service to use Salesforce’s enterprise software, said people familiar with the talks, signaling a thaw between two longtime rivals. The partnership will make Salesforce’s customer-management programs available on Microsoft’s Azure service, said the people, who asked not to be identified because the discussions are confidential. Salesforce will also commit to using Azure to host some of its own applications and will integrate data from Salesforce products into Microsoft’s Office programs, the people said. An agreement would mark a shift in what has sometimes been a fractious relationship between the two companies. In 2010, Microsoft sued Salesforce for patent infringement, setting off a countersuit before the companies settled later that year. Microsoft in 2005 also announced plans to “give Salesforce a very effective run for their money” with a competing product and in 2010 ran an anti-Salesforce ad campaign with the tagline “Don’t Get Forced.”
