Slack has scored another major win, as Amazon Web Services (AWS) has adopted the messaging platform for all its employees.

The deal is part of a collaboration between the two companies, with Slack continuing to use AWS as its preferred cloud provider. Meanwhile, AWS will deploy Slack to all its employees to help teams communicate more efficiently.

As part of Slack’s ongoing reliance on AWS, the platform will migrate to Amazon’s Chime voice and video calling service to power Slack Calls. The company assures customers they will not notice any difference in the short-term. In the long-term, using Amazon Chime to power Slack Calls will enable the company to add more features and advanced capabilities.

“The future of enterprise software will be driven by the combination of cloud services and workstream collaboration tools,” says Stewart Butterfield, the co-founder and CEO of Slack. “Strategically partnering with AWS allows both companies to scale to meet demand and deliver enterprise-grade offerings to our customers. By integrating AWS services with Slack’s channel-based messaging platform, we’re helping teams easily and seamlessly manage their cloud infrastructure projects and launch cloud-based services without ever leaving Slack.”

The partnership will likely benefit both companies, with Slack’s customers standing the most to gain.
