Final answer:
PaaS provides platforms for app development without managing infrastructure, with examples including Azure App Service, GApp Engine, and AWS Elastic Beanstalk. It's scalable and eases app creation for developers.
Step-by-step explanation:
Platform as a Service (PaaS) is a cloud computing offering that provides users with a platform allowing them to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Cloud providers deliver a range of computing platforms in PaaS, which can include web servers, development tools, database management systems, analytics services, and more.
These platforms enable developers to focus on the creative side of app development, leaving the hardware, software patches, and other infrastructure concerns to the cloud provider. The services offered under PaaS are scalable and highly available, which is critical for business continuity and handling varying loads. Examples of PaaS offerings include Microsoft Azure's App Service, G App Engine, and Amazon Web Services Elastic Beanstalk. By using PaaS, businesses can reduce costs, streamline workflows, and accelerate development cycles for various applications.
