Deployment platforms are environments where software applications are hosted and run. They provide the necessary infrastructure, tools, and services to manage the deployment process, ensuring that applications are accessible to users. Common examples of deployment platforms include cloud services like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. These platforms support various programming languages and frameworks, allowing developers to deploy applications quickly and efficiently. They often include features such as scalability, security, and monitoring, which help maintain application performance and reliability. By using deployment platforms, organizations can streamline their development processes and reduce operational costs.
