Earlier we discussed about the cloud computing and why we need cloud computing. Here we will talk about service and deployment models for cloud computing.
There are below three cloud computing service models:
IaaS – Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. IaaS quickly scales up and down with demand, letting you pay only for what you use.
PaaS – Platform as a service (PaaS) is a complete development and deployment environment in the cloud. Pricing is based on pay-as-you-go basis and access them over a secure Internet connection. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing and updating.
SaaS – Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools (such as Microsoft Office 365).
Managing Different Service Models:
Cloud Computing Deployment Models:
We have four deployment models – Public Cloud, Private Cloud, Hybrid Cloud and Community. There are below diagram that explain all four deployment models.
We can see that most of the companies use the Public cloud for the business.
