Communication is a technology category published by Microsoft under the name Azure Communication Services, providing APIs to embed voice, video, chat, SMS, and email capabilities into applications. It solves the challenge of building secure, scalable, real-time communication experiences without managing underlying infrastructure, and sits within the Microsoft Azure cloud platform as a set of programmable services for developers. The technology includes Voice and Video Calling, enabling real-time interactions in browsers or native apps; Chat, for rich text messaging; SMS, to send and receive text messages globally; Email, for transactional email delivery; Phone Numbers, to provision and manage telephony resources; and Call Automation, for building server-driven call workflows. Additional capabilities include UI Library, offering prebuilt user interface components, and integration with Microsoft Teams for hybrid communication scenarios. This technology is for software developers, full-stack engineers, and cloud architects who need to integrate secure, compliant, and scalable communication features into custom applications, particularly in healthcare, customer service, and collaboration platforms where real-time engagement is essential.
