What are Cloud Computing Services [IaaS, CaaS, PaaS, FaaS, SaaS]
Difference between IaaS SaaS PaaS CaaS FaaS!!
Today, everyone are moving towards Cloud World (AWS/GCP/Azure/PCF/VMC). It might be a public cloud, a private cloud or a hybrid cloud.
But are you aware of what are Services Cloud Computing provides to us ????
Majorly there are three categories of Cloud Computing Services:
a) Infrastructure as a Service (IaaS) : It provides only a base infrastructure (Virtual machine, Software Define Network, Storage attached). End user have to configure and manage platform and environment, deploy applications on it.
AWS (EC2), GCP (CE), Microsoft Azure (VM) are examples of Iaas.
b) Software as a Service (SaaS) : It is sometimes called to as “on-demand software”. Typically accessed by users using a thin client via a web browser. In SaaS everything can be managed by vendors: applications, runtime, data, middleware, OSes, virtualization, servers, storage and networking, End users have to use it.
GMAIL is Best example of SaaS. Google team managing everything just we have to use the application through any of client or in browsers. Other examples SAP, Salesforce .
c) Platform as a Service (PaaS): It provides a platform allowing end user to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
Google App Engine, CloudFoundry, Heroku, AWS (Beanstalk) are some examples of PaaS.
Below fig 1.0 while give you more idea on it.
d) Container as a Service (CaaS): Is a form of container-based virtualization in which container engines, orchestration and the underlying compute resources are delivered to users as a service from a cloud provider.
Google Container Engine(GKE), AWS (ECS), Azure (ACS) and Pivotal (PKS) are some examples of CaaS.
e) Function as a Service (FaaS): It provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure.
AWS (Lamda), Google Cloud Function are some examples of Faas
Hope this gives you clear idea on what are Cloud Computing Services provided in market!!!!!!
