Azure Fundamentals
What is Azure?
- Azure is a cloud computing platform offered by Microsoft, providing a wide range of services for computing, storage, networking, databases, and more.
What are the key benefits of using Azure?
- Scalability: Easily scale resources up or down based on demand.
- Cost-effectiveness: Pay-as-you-go pricing, eliminating upfront costs.
- Reliability: Highly reliable and available infrastructure with multiple availability zones.
- Flexibility: Wide range of services to choose from, allowing you to build any type of application.

Explain the concept of IaaS, PaaS, and SaaS.
- IaaS (Infrastructure as a Service): Provides fundamental computing resources like servers, storage, and networking (e.g., Virtual Machines, Virtual Networks).
- PaaS (Platform as a Service): Provides a platform for developing, running, and managing applications without worrying about the underlying infrastructure
1 (e.g., App Service, Functions). - SaaS (Software as a Service): Provides applications accessible over the internet (e.g., Office 365, Dynamics 365).
What are the different Azure regions and availability zones?
- Regions: Geographical locations where Azure data centers are located.
- Availability Zones: Separate, isolated locations within a region, providing high availability.
What is the Azure Management Console?
- A web-based interface for managing Azure services.
