How To Implement Azure Hybrid Cloud Architecture: A Step-By-Step Guide

The following are the steps of implementations as follows:

Assessment and Planning: To implement Azure Hybrid Cloud Architecture, the first two steps are to assess your infrastructure, applications, and business requirement to migrate or run in the cloud. One of the tasks in this step is to select the workload which can be migrated to cloud or running on cloud as required and which deployment model suits your organization .
Connectivity Setup: To maintain integration between on-premises and Azure cloud services require connectivity. Azure Virtual Network for network isolation, ExpressRoute for private connections, or VPN Gateway for secure VPN connections using the internet is mainly used for the following network configuration setup;
Identity Integration: Identity integration: Integrating your on-premises Active Directory with Azure Active Directory makes possible more efficient single sign-on, multi-factor authentication as well as seamless access to resources across hybrid environments. This can be done via Azure AD Connect, which synchronizes identities between on-premises and cloud environments.
Resource Deployment: Deploying Azure Stack can bring Azure services to your on-premises environment, providing a consistent experience of development and operation. This will enable you to install infrastructure for Azure Stack, configure resource providers and then deploy services like virtual machines, containers and Azure App Service.
Management and Governance: Azure Arc enables centralized management, governance and compliance across hybrid environments. This means registering on–premises servers, Kubernetes clusters and other resources with Azure Arc, giving features such as Azure Policy.

On discussing indetail the implementation guide will looks as follows:

Step 1: Azure Virtual Network setup and configuration

Azure Portal: first, access the Azure portal (https://portal.azure.com) and follow the subsequent steps listed below.
Create Virtual Network: press on “Create a resource” browsing the categories “Networking” then “Virtual Network.” Afterward, fill the prompted columns related to the network’s name, address space, and subnet configuration.
Subnets configuration: define the subnets that your virtual network should utilize. If necessary, create one for on-site connectivity as well.
