You’ll gain a solid grasp of the primary services within Azure, such as compute services (e.g., Virtual Machines, Kubernetes), storage (Blob Storage, Disk Storage), databases (SQL Database, Cosmos DB), and networking (VNets, Load Balancer, Application Gateway). This knowledge is crucial when working with Azure in real-world scenarios, as these services form the backbone of most Azure deployments. - Security and Compliance Awareness:
Security is a top priority in the cloud, and AZ-900 ensures you’re aware of Azure’s security offerings, such as Azure Active Directory, Azure Security Center, and compliance certifications. Understanding how to secure and manage identities and data in the cloud is key to successfully working with Azure. - Optimization and Cost Management:
The exam also highlights cost management, a critical aspect of using cloud services efficiently. Azure’s Cost Management + Billing, Pricing Calculator, and Autoscale help you plan your resources wisely and avoid overspending—an essential skill for cloud administrators and architects. - Hands-On Experience:
While studying for the AZ-900, hands-on experience is invaluable. Utilize Azure’s free trial to explore services, set up virtual machines, and interact with cloud resources to solidify your theoretical knowledge. Practical experience is key to understanding how Azure works in real scenarios. - Exam Strategy:
- Focus on understanding concepts over memorizing specifics.
- Leverage Microsoft Learn modules, Azure documentation, and practice exams to familiarize yourself with exam patterns.
- Don’t be overwhelmed by the vastness of the Azure platform. The AZ-900 is a high-level overview, and while it covers many topics, it doesn’t expect deep technical expertise.
- Focus on understanding concepts over memorizing specifics.
- Certification as a Gateway:
The AZ-900 certification can be a stepping stone to further Azure certifications, such as AZ-104 (Azure Administrator) or AZ-204 (Azure Developer), which delve deeper into specific areas of cloud infrastructure and development. Once you have the AZ-900, you’ll be well-positioned to continue expanding your Azure knowledge and skillset, which will increase your marketability in the cloud industry.
