Today the cloud has become one of the most appropriate places to store and manage sensitive databases and the COVID-19 pandemic has accelerated the adoption of the cloud at every level. The cloud not just makes a secure environment to monitor the data but also allows to access your crucial information from anywhere through any device. Flexibility,
scalability,
ease-of-configuration,
savings and security, this is all that cloud services offers.
IaaS vs PaaS vs SaaS: 3 Core Service Models In this write up, we will delve into three
IaaS Infrastructure as a Service
PaaS Platform as a Service
different cloud service models IaaS, PaaS, and SaaS along with their examples.
Saas Software as a Service
IaaS (Infrastructure as a Service) IaaS is a cloud computing solution that offers provisioning, managing, and computing service resources over the Internet, like servers, storage, devices, and virtualization devices. Infrastructure as a Service (IaaS) offers the technologies and capabilities of quality data centers even without any significant capital investment of IT infrastructure.
IaaS Best Examples
WHY IAAS?
All the resources are available and ready to -use No need to invest in physical devices and software Pay as you use: Pay only for the resources in use No need to worry about physical data centre's security Access the information and resources from anywhere
