 What is Vnet Peering in azure?

 

·       Virtual Network (VNet) peering in Azure is a mechanism that allows connecting two Azure virtual networks.

 

·       When we peer two VNets, they appear as one network to the resources connecting to them.

 

·       VNet peering enables resources in one VNet to communicate with resources in another VNet securely, without the need for a gateway or additional configuration.

 

Regional VNet peering :- connects Azure virtual networks in the same region.

Global VNet peering :-  connects Azure virtual networks in different regions.

 

Key points about VNet peering in Azure:

 

Global Reach: VNet peering can be set up across different Azure regions, making it a global solution.

 

Transitive Routing: If VNet A is peered with VNet B, and VNet B is peered with VNet C, then traffic can flow between VNets A and C through the peering connection with VNet B. This is known as transitive routing.

 

Secure Connectivity: Communication between peered VNets stays within the Azure backbone network, ensuring security and low-latency connectivity.

 

No Gateway Required: Unlike VPN or ExpressRoute connections, VNet peering doesn't require a gateway. It's a direct connection between VNets.

 

Resource Isolation: Each VNet remains independent and maintains its own address space. Peering does not result in the merging of address spaces.

Landing Zone

What is Azure landing zone   An Azure Landing Zone is a set of best practices and guidelines provided by Microsoft to help organizations establish a well-structured and standardized foundation for deploying workloads and applications in the Microsoft Azure cloud environment. It is essentially a framework that assists organizations in setting up their Azure environment with a focus on key areas such as security, governance, compliance, and operational efficiency. Here are the main aspects and objectives of an Azure Landing Zone: 1. ** Security **: Implementing robust security measures to protect data and resources in Azure, including network security, identity and access management, and compliance with security standards. 2. ** Governance **: Defining and enforcing policies and standards for resource provisioning, naming conventions, and compliance requirements. This ensures that Azure resources are created and managed consistently across the organization. 3. ** Networking **: ...

Migration

  Prepare a machine for the replication appliance The Migration and modernization tool uses a replication appliance to replicate machines to Azure. The replication appliance runs the following components. Configuration server : The configuration server coordinates communications between on-premises and Azure, and manages data replication. Process server : The process server acts as a replication gateway. It receives replication data; optimizes it with caching, compression, and encryption, and sends it to a cache storage account in Azure. Run a test migration When delta replication begins, you can run a test migration for the VMs, before running a full migration to Azure. We highly recommend that you do this at least once for each machine, before you migrate it. Running a test migration checks that migration will work as expected, without impacting the on-premises machines, which remain operational, and continue replicating. Test migration simulates the migration by creating an Azur...
