Amazon Web Services dominates the market for cloud server and storage services and has made inroads in other enterprise technologies like databases. Now it wants to become a more potent competitor in productivity apps, where Microsoft and Google are well established.

AWS is working on upgrades to its WorkMail email-calendar app and its WorkDocs file storage-collaboration app to make them more attractive to corporate customers, according to two people who do business with the company. AWS has also told some large corporate customers it’s considering bundling these apps with its recently launched Chime video conferencing apps into a new productivity app suite that will compete with Google G Suite and Microsoft Office 365, according to a person who’s been briefed on the cloud unit’s plans.
