PaaS stands for "Platform as a Service" in cloud services. This model provides developers with a cloud-based platform to build, deploy, and manage applications without the complexity of maintaining underlying infrastructure. PaaS solutions offer a range of tools and services, such as middleware, development frameworks, and database management, facilitating faster application development and deployment. Examples of PaaS providers include Heroku, Google App Engine, and AWS Elastic Beanstalk. By leveraging PaaS, organizations can focus on innovation and application development while minimizing operational burdens associated with hardware and software management.
