In a direct challenge to primary cloud services rivals Microsoft Azure and Google Cloud Platform, the new product will offer all the usual business e-mail and calendaring functionalities and will even let users work with existing providers, such as Microsoft Outlook, Web-based services or mobile apps running on iOS or Android.
"Today, businesses face a difficult choice when it comes to e-mail," AWS said in a statement. "Hosting e-mail on-premises requires expensive hardware, complex software licensing and ongoing maintenance work. Existing cloud e-mail services may help with some of these problems, but they either don't offer the security features businesses require (like strong encryption key management and full control over data location), don't integrate with existing corporate directories, or don't support popular Microsoft Outlook features like shared calendaring. Now, Amazon WorkMail delivers the simplicity and on-demand access of a managed cloud service that works with popular e-mail clients and also has the security controls enterprises need."
