🌌 Azure Fleet

🔹 Core Concept
Azure Virtual Machine Fleet allows you to manage and orchestrate a large set of virtual machines as a single entity, providing centralized management, scaling, and operational efficiency across multiple VMs.

🔹 Purpose
Designed for large-scale, high-performance workloads where managing individual VMs is inefficient. Ideal for mission-critical applications, batch processing, and compute-intensive scenarios.

🔹 Automatic Scaling
Supports horizontal scaling by automatically adding or removing VMs based on workload demands, metrics, or schedules defined in Azure Monitor.

🔹 Flexible Orchestration
VM Fleet provides centralized configuration and deployment, allowing uniform updates and operational consistency across all VMs in the fleet.

🔹 Integration with Load Balancing
Seamlessly integrates with Azure Load Balancer and Application Gateway to distribute traffic evenly across VMs, improving availability and performance.

🔹 High Availability
VMs in a fleet can be distributed across fault domains and update domains, reducing the impact of hardware failures or maintenance events.

🔹 Integration with Availability Zones
Fleets can span multiple Availability Zones within a region, providing zone-level redundancy and ensuring high uptime for critical applications.

🔹 Support for Custom Images
Allows deployment using Azure Marketplace images, custom images, or Shared Image Gallery, ensuring consistent environments across all VMs.

🔹 Security & Compliance
Integrates with Azure Policy, Managed Identities, and Microsoft Defender for Cloud, maintaining a secure and compliant fleet infrastructure.

🔹 Automation & Management
Supports ARM templates, Bicep, Terraform, and Azure CLI for automated provisioning, configuration, and updates of all fleet VMs.

🔹 Monitoring & Insights
Fully integrated with Azure Monitor, Log Analytics, and Metrics to track VM performance, scaling events, health, and utilization across the fleet.
