Types of Cloud Computing Services
Cloud computing services are typically categorised based on the level of control and responsibility shared between the cloud provider and the customer. Understanding these service models helps organisations choose solutions that best match their technical requirements, resources, and business objectives.
Infrastructure as a Service (IaaS)
Infrastructure as a Service provides fundamental computing resources such as virtual machines, storage, networking, and servers through the cloud. Organisations manage their applications and operating systems while the provider maintains the underlying infrastructure.
IaaS is suitable for businesses requiring flexibility and customisation. Examples include Amazon EC2, Microsoft Azure Virtual Machines, and Google Compute Engine.
Platform as a Service (PaaS)
Platform as a Service offers a complete development and deployment environment in the cloud. Developers can build, test, and deploy applications without managing servers or infrastructure.
PaaS is particularly useful for software development teams seeking to accelerate application delivery. Examples include Google App Engine, Microsoft Azure App Service, and Heroku.
Software as a Service (SaaS)
Software as a Service delivers ready-to-use applications through a web browser or internet connection. Users access software without installing or maintaining it locally.
SaaS is ideal for organisations seeking convenience, accessibility, and lower maintenance requirements. Examples include Microsoft 365, Salesforce, Zoom, and Google Workspace.
Additional Cloud Categories
- Function as a Service (FaaS): Allows developers to run specific functions or code without managing servers, commonly used in serverless computing
- Database as a Service (DBaaS): Provides cloud-hosted databases that eliminate the need for organisations to manage database infrastructure
- Disaster Recovery as a Service (DRaaS): Enables businesses to back up and recover systems quickly during disruptions or emergencies
