IV. Examples: Amazon Web Services (AWS) EC2, Microsoft Azure Virtual Machines, Google Compute Engine.
Platform as a Service (PaaS):
There are some key point are as follow -:
v Provides a platform for developing, testing, and deploying applications.
v Provides platforms for developing, deploying and managing apps without building infrastructure. Example: AWS Elastic Beanstalk.
v Customers can build and deploy applications without managing the underlying infrastructure.
v Examples: AWS Elastic Beanstalk, Google App Engine, Microsoft Azure Web Apps.
