AZ-900 Microsoft Azure Fundamentals | Azure Certification

Maximize app uptime with Azure high availability through multi-data center redundancy, automated failover, and load balancing, and scale cost-efficiently via manual, automatic, and scheduled options—vertical and horizontal.

Explore Azure service-level agreements and how uptime guarantees apply to virtual machines (99.99%) and App Service (99.95%). Learn the compensation credits (10%, 25%, 100%) when uptime falls short.

Explore high-availability options for Azure virtual machines, including availability zones, VM scale sets, and availability sets, demonstrated through the Azure portal, the Virtual Machine Management page, and the creation wizard.

Explore software as a service, a cloud computing model delivering developed applications online with minimal technical effort, ideal for scalable, ready-to-use tools like Office 365, where Azure handles shared responsibility.

Explore how Azure regions and region pairs provide resilience by locating data centers. Learn to choose a region during resource creation, and note bidirectional and unidirectional pairs and failover behavior.

Explore Azure Functions, the serverless offering, by creating a function app in a resource group, selecting .NET, and adding an HTTP-triggered function tested via code and URL.

Explore how Azure App Service offers a versatile, comprehensive solution that supports web apps, api apps, web jobs, and mobile apps with automatic scaling, language support, and Docker image deployment.

Explore Azure authentication methods, from standard passwords to single sign-on, multi-factor and passwordless options, including Windows Hello, Microsoft Authenticator, and FIDO2 keys, highlighting security strengths and weaknesses.

Learn how Azure conditional access regulates resource access by identity signals such as location, device, and application, and enforce granular multi-factor authentication or access decisions.

Adopt defense-in-depth and zero-trust models in Azure to enforce least-privileged access by authenticating and authorizing every request, while layered security protects data, networks, and applications.

Estimate costs for provisioned Azure resources using the pricing calculator. Explore analytics, CICD, and machine learning scenarios, save estimates, and share them with your team after signing in.

Use the total cost of ownership calculator to compare on-premises infrastructure with Azure cloud, estimating five-year costs across servers, databases, storage, network, power, and IT labor.

Azure blueprints enable standardized, secure deployments by defining resources that meet organizational standards, enforcing policies across subscriptions, and supporting artifacts like role assignments, policies, templates, and resource groups.

Master governance in Azure by using Azure Policy and Azure Blueprint to define policy definitions and initiatives, then apply artifacts such as templates, role assignments, and policies across scopes.

Apply resource locks to protect Azure resources from accidental edits or deletions, including delete and read-only types. Bypass role-based access control with these locks and require removal to update resources.

Discover the service trust portal and how Microsoft implements security, privacy, and compliance practices. Learn to save and pin documents, receive update notifications, and navigate My Library and All Documents.
