Study Notes
Azure 900 Study Course
- The Azure 900 study course is designed to help users prepare for the Microsoft Azure Fundamentals exam (AZ-900).
- The course covers fundamental concepts of cloud computing, Azure services, and how to manage and deploy applications on Azure.
Azure 900 Exam & Benefits
- The AZ-900 exam leads to the Microsoft Azure Fundamentals certification.
- The certification demonstrates a basic understanding of cloud concepts and Azure services.
Cloud Service Principles
- A key principle of a cloud service is the concept of shared responsibility.
- High availability in a cloud service refers to the ability of the service to remain operational even if some components fail.
Cloud Service Types
- Public clouds are typically multi-tenant & externally hosted.
- Private clouds are dedicated to a single organization.
Cloud Service Locations
- The main benefit of a cloud service with multiple locations is disaster recovery, ensuring service continuity in case of failures.
- Brazil replicates to the US South region.
- Each Azure region has three availability zones.
- Availability zones physically separate infrastructure for improved resilience.
Cloud Service Resources
- Azure offers resources with both zone-redundant and zonal options.
- The zone-redundant option replicates data across multiple availability zones, while the zonal option keeps data within a single zone.
Cloud Service Expenditure
- Capital expenditure (CapEx) refers to investments in hardware and infrastructure.
- Operational expenditure (OpEx) covers the ongoing costs of using the cloud service.
Cloud Service Responsibilities
- The shared responsibility model between customer and provider focuses on security.
Cloud Service Workloads
- Public clouds are well-suited for general-purpose workloads.
- Azure's China cloud is unique as it is managed by a Chinese company.
Azure Regions
- Azure regions are geographically dispersed locations that house resources and offer cloud services.
- Regions are designed to provide disaster recovery and high availability.
Cloud Service Levels
- Infrastructure as a Service (IaaS) provides the most flexibility with full OS access.
- Platform as a Service (PaaS) offers higher abstraction, focusing on application and data management.
- Software as a Service (SaaS) is responsible for business functions, requiring the least customer involvement.
Cloud Service Benefits
- PaaS benefits over IaaS include simplified management and reduced operational burden.
Cloud Service Redundancy
- Storage accounts do not offer a zone-redundant option.
- For a service to survive data center failure, the recommended solution is to use availability zones.
- When choosing a service with availability zones, understand whether the service is zone-redundant or zonal.
