Setup Availability Sets: Understand how to configure Availability Sets to ensure your VMs are highly available and resilient to failures. Update Domains and Fault Domains: Discover the role of Update and Fault Domains in maintaining VM availability during planned maintenance or hardware failures. Availability Zones: Explore Azure Availability Zones and how they help improve the availability and redundancy of your Virtual Machines. Vertical and Horizontal Scaling: Learn the difference between vertical and horizontal scaling, and how to apply them to your Azure VM infrastructure to meet performance demands. Create and Manage VM Scale Sets: Understand how to create and manage VM Scale Sets to automatically scale your applications based on demand. Demo: Create and Manage VM Scale Set: Watch a hands-on demonstration where we create and manage a VM Scale Set to manage VM instances dynamically. This video is packed with practical insights to help you optimize the performance and availability of your Azure Virtual Machines while preparing for the AZ-104 certification exam.
