We can represent our network within the cloud using VNet. VNet logically isolates our instances launched in the cloud, from the rest of our resources. The various power state of a Virtual Machine is: Running, Starting, Stopping, Deallocating, etc.
- Why we use VNet?
Virtual Network (VNet) in Microsoft Azure is used to create private, isolated networks in the cloud. The primary reasons for using VNet include:
- Isolation: VNet allows you to isolate resources within your Azure environment. This isolation helps in maintaining network security by controlling inbound and outbound traffic.
- Connectivity: VNet enables you to connect and extend your on-premises network to the Azure cloud securely. You can establish site-to-site VPNs or use Azure ExpressRoute for a dedicated, private connection.
- Segmentation: VNet allows you to segment your resources into subnets, providing a way to organize and manage your virtual machines, services, and other resources effectively.
- Security: By implementing Network Security Groups (NSG) and other security features within a VNet, you can control and monitor traffic flow to and from resources, enhancing overall security.
- Scaling: VNet supports the scalability of your applications by providing the flexibility to scale resources within the virtual network based on demand.
- Name the power states of a Virtual Machine:
Virtual Machines (VMs) in Microsoft Azure have several power states, representing different states of operation. The common power states include:
- Starting: The VM is being initiated and is in the process of starting up.
- Running: The VM is fully operational and running the configured operating system and applications.
- Stopping: The VM is in the process of shutting down, allowing the operating system and applications to gracefully stop.
- Stopped: The VM is fully stopped, and no resources are allocated to it. This is a deallocated state, and you are not billed for compute resources.
- Deallocating: The VM is being deallocated, meaning it is fully stopped and no longer consuming compute resources. This state is often used to minimize costs when the VM is not needed.
- Rebooting: The VM is being restarted, typically to apply changes or updates without a full shutdown and start-up process.
Understanding and managing these power states is crucial for effective resource utilization, cost management, and maintenance of virtual machines in Azure.
