Is there an exhaustive list of azure services classified into IaaS, PaaS or SaaS?

Currently, there isn't a comprehensive, officially sanctioned list from Microsoft that categorizes all Azure services into IaaS, PaaS, or SaaS. However, I can help classify the services you mentioned based on common understanding:

• Azure Load Balancer: IaaS
• Azure VNet (Virtual Network): IaaS
• Azure UDR (User Defined Routes): IaaS
• Azure Role-Based Access Control (RBAC): IaaS (but can be seen as part of management for PaaS)
• Azure Key Vault: PaaS
• Azure Monitor: PaaS
• Azure Backup: PaaS
• Azure DDoS Protection: PaaS
• Azure WAF (Web Application Firewall): PaaS
• Log Analytics: PaaS
• Defender for Cloud: PaaS
• Defender Scan (Pipeline): PaaS
• Sentinel: PaaS
• Azure AD (Entra ID): SaaS
• Microsoft Entra MFA: SaaS
• Azure PIM (Privileged Identity Management): SaaS

These classifications are based on the typical usage and service models in Azure. For specific security standards and controls, it’s best to refer to Azure's shared responsibility model and the documentation for each service to understand the security implications.

Hello @Wathanachai Kaewwilai ,

Cloud computing makes it possible to access computing resources over the internet instead of maintaining physical hardware. These resources include servers, storage, networking, databases, and applications. The three most common service models Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) provide different ways to use and manage those resources.

While IaaS, PaaS, and SaaS all deliver cloud resources, each model puts a unique spin on how much control you have, where responsibilities lie, and how much is managed by the cloud provider. Whether you want hands-on access or a hassle-free experience, understanding these differences helps you choose the right fit for your needs.

Level of control and management responsibilities

IaaS offers the most control, with management of operating systems, applications, and data remaining with the customer, while the provider manages the underlying hardware.

PaaS focuses on application development, with infrastructure and runtime managed by the provider, leaving applications and data under the customer’s oversight.

• SaaS is fully managed, delivering ready-to-use applications where infrastructure, updates, and maintenance are handled by the provider.While IaaS, PaaS, and SaaS all deliver cloud resources, each model puts a unique spin on how much control you have, where responsibilities lie, and how much is managed by the cloud provider.
