Study Notes

Azure Infrastructure Design

Azure infrastructure design involves planning and implementing cloud-based solutions.
Considerations include network topology, resource grouping, virtual machines (VMs), storage options, and security.
Virtual Networks (VNETs) provide isolated networks within Azure, enabling segmentation and control.
Azure Resource Manager (ARM) templates automate deployment and management of resources.
Deployment models include resource groups for organization, and various deployment methods like template-based deployment from Azure portal, Azure CLI, PowerShell, and ARM templates.
Key deployment strategies focus on high availability, scalability, and resilience.
Considerations for design include choosing the right compute resources (e.g., VMs, serverless functions).
Storage options like Blob storage, Queue storage, Table storage, and File storage should be chosen to meet application needs.
Load balancing and scaling strategies are crucially important for high availability and performance, particularly in dynamically scaling workloads.

Migration Strategies

Migrating on-premises infrastructure to Azure involves careful planning and execution, considering business requirements and technical aspects.
Approaches include lift-and-shift, rehosting, refactoring, and re-platforming.
Lift-and-shift involves moving applications and data to Azure without significant code changes, suitable for applications with stable architectures.
Rehosting requires minimal modification for existing applications or services to suit Azure infrastructure.
Refactoring involves redesigning applications to leverage Azure-specific services, improving scalability and performance.
Re-platforming, also known as rearchitecting, involves significant code changes or modernization to take advantage of Azure platforms.
Azure Migration Center is a powerful tool for automated assessment and migration planning.
Data migration strategies are crucial, encompassing different tools and methods based on data volume and types.
Key stages of a migration usually include assessment, planning, migration, testing, and validation.
Data migration can be performed either in parallel with application migration or afterward.

Security Considerations

Azure security focuses on various layers, encompassing network, data, and identity management.
Implement strong access controls, using role-based access control (RBAC) to limit access to sensitive resources.
Encryption at rest and in transit protect data confidentiality.
Robust network security including firewalls and virtual networks (VNETs) are crucial.
Threat detection and response mechanisms, such as Azure Security Center, play a key security role.
Maintaining up-to-date security patches and configurations is critical for preventing vulnerabilities.
Identity management, using Azure Active Directory (Azure AD), is essential for secure access management and authorization.
Secure coding practices enhance the overall security posture of applications.

Operational Governance

Operational governance encompasses policies, processes, and procedures for managing Azure resources effectively.
Resource tagging helps in organizing and tracking resources.
Implementing appropriate service level agreements (SLAs) fosters better collaboration and clear expectations among teams involved.
Monitoring and logging proactively identify and resolve issues, reducing downtime.
Key metrics and KPIs should be established for effective performance tracking and improvement.
Policy as Code using Azure Policy defines and enforces policies across Azure resources.
Automation through Azure DevOps assists in achieving significant efficiency by automating infrastructure tasks.
This ensures consistency, compliance, and cost optimization.

Cost Management

Cost management in Azure involves strategies to optimize spending and track resource utilization.
Resource tagging helps in grouping and identifying resources for cost allocation.
Implementing cost optimization tactics, like rightsizing virtual machines, leveraging serverless options, and using reserved instances accordingly will significantly impact operational costs.
Using Azure Cost Management provides insights into cost trends and usage patterns.
The Azure portal provides insights into billing, consumption, and costs on a regular basis, creating an excellent basis for understanding and optimizing expenses.
Cost alerts help in proactive identification of potential spending problems and timely interventions.
Implementing accurate costing strategies is crucial for controlling expenditure.
Careful selection of services based on their cost-effectiveness is also key.
