Worked on a Project Infrastructure architecture application for multiple clients. , Architected and deployed a 3-tier infrastructure using Azure, ensuring secure and scalable separation of the web, application, and database layers. • Configured Azure Virtual Network (VNet) and multiple Subnets to isolate services and enforce security between the tiers. • Implemented Azure Firewall and VPN Gateway to ensure secure access to the infrastructure, protecting both internal and external traffic. • Utilized Azure Bastion Service for secure remote management of virtual machines without exposing public IPs. • Configured Private Load Balancer to manage internal traffic across the application tier, ensuring optimal distribution and redundancy. • Integrated Azure Active Directory (Azure AD) for identity management and role-based access control (RBAC) across the entire architecture. • • Configured Azure Scale Sets to ensure horizontal scaling of application resources, optimizing performance and reducing downtime. • Leveraged Azure Web App, Azure SQL, and Traffic Manager to enable high availability, load balancing, and global routing of traffic to web applications and databases. Streamlined deployment and management processes using Infrastructure-as-Code (IaC) tools and automated the continuous integration
