The encrypted messaging app Signal faced criticism after being affected by a recent Amazon Web Services (AWS) outage. Signal’s president, Meredith Whittaker, defended the company’s choice to use AWS, pointing out the lack of alternative options due to the concentrated power in the cloud infrastructure industry. Whittaker emphasized that running a global, real-time communication platform like Signal requires the robust capabilities offered by major cloud providers like AWS, Microsoft Azure, and Google Cloud. Building a similar infrastructure independently would be cost-prohibitive. Signal’s use of encryption ensures user privacy, even though it partially relies on AWS for its operations.
