Cloud Basic Notes

Cloud Basics

IaaS

IaaS (infrastructure as a service) means that Azure/AWS can/will provide you with things such as those listed below as a service:

• Routers and Switches
• Firewall
• Security
• Physical Infrastructure
• Load Balancers
• Clustering
• Storage
• Resiliency and Backup

It also means Azure/AWS are responsible for that infrastructure.

The user will then be responsible for installation, configuration and management of the software running on that infrastructure provided by the cloud provider.

PaaS

PaaS (Platform as a Service), provides an environment for building, testing and deploying software applications. It is a complete development and deployment environment in the cloud.

With PaaS in place the developer can focus on development only and there is no need to spend time on learning how to configure or to maintain such environments. The cloud provider is responsible for operation system management, and network and service configuration.

SaaS

SaaS (Software as a Service) allows data to be accessed from any device. It is centrally hosted and managed and you can scale it to different locations in order to ensure best performance.
