Cloud Service Models: IaaS, PaaS, SaaS 🏢🛠️
Understanding the primary cloud service models is crucial:
IaaS (Infrastructure as a Service): Provides virtualized hardware resources like servers, storage, and networking. Users manage OS and applications. Example: Amazon EC2, Google Cloud Compute.
PaaS (Platform as a Service): Offers development platforms—operating systems, runtime, and middleware—letting developers focus on code. Example: Google App Engine, Heroku.
SaaS (Software as a Service): Delivers software applications via the internet on a subscription basis. Users access apps through browsers. Example: Google Workspace, Salesforce.
