Deployment of a Three-Tier Application on Azure Platform

This project involved deploying a three-tier web application on the Azure cloud platform, encompassing a web tier, application tier, and database tier. The web tier handled client requests, the application tier processed business logic, and the database tier stored and managed data. The entire infrastructure was automated using Terraform, while PowerShell and Python scripts were employed for various configurations. The application was containerized using Docker and orchestrated with Azure Kubernetes Service (AKS), while Azure DevOps enabled CI/CD. Azure SQL served as the backend database.

• Azure Kubernetes Service (AKS): For orchestrating the application tier's containerized microservices.

• Azure App Service (Web Tier): Hosted the web tier of the application for handling HTTP requests and static content.

• Terraform: Automated the provisioning of Azure infrastructure.

• PowerShell & Python: For scripting and automation tasks across the environment.

• Docker: Containerized the web and application tiers for consistent and scalable deployments.

• Azure SQL: Managed database service for storing and managing application data.

• Azure DevOps: Enabled CI/CD pipelines for continuous integration and deployment.

• Azure Virtual Network (VNet): For secure networking and communication across tiers.

• Architecture Design and Implementation: Designed a robust three-tier architecture on Azure that included a web tier (Azure App Service), application tier (AKS), and database tier (Azure SQL), ensuring scalability, security, and high availability.

• Web Tier Setup on Azure App Service: Deployed the web tier on Azure App Service, hosting static content and handling incoming HTTP traffic with built-in scaling and load balancing.

• Container Orchestration with AKS: Deployed containerized services in the application tier using AKS for seamless scaling and management of microservices.

• Infrastructure Automation with Terraform: Automated the provisioning of the entire Azure infrastructure, including Azure App Service, AKS, and Azure SQL, using Terraform for repeatable and consistent deployments.

• CI/CD Pipeline with Azure DevOps: Configured Azure DevOps pipelines to automate application builds, tests, and deployments for both the web and application tiers.

• Database Management with Azure SQL: Managed and configured Azure SQL for the backend, ensuring secure, scalable, and high-performance data management.

• Scripting with PowerShell and Python: Developed PowerShell and Python scripts for automating configurations and backend processes.

• Network Security and Configuration: Set up and managed Azure Virtual Network (VNet) to ensure secure communication between the web, application, and database tiers.

• Fully Deployed Three-Tier Architecture: Deployed a fully functional three-tier architecture on Azure, with a responsive web tier, scalable application tier, and a secure, performant database tier.

• Scalable Web Tier: The web tier, hosted on Azure App Service, automatically scaled based on traffic, ensuring high availability and performance for end users.

• Efficient Container Orchestration: Used AKS to manage the application tier, enabling automatic scaling and seamless management of microservices.

• Infrastructure as Code (IaC): Leveraged Terraform to automate the infrastructure setup, significantly reducing deployment time and ensuring consistency across environments.

• Automated CI/CD: The Azure DevOps pipelines streamlined the deployment process, enabling fast, reliable updates to both the web and application tiers.

• Secure and Optimized Network: Implemented secure communication between the tiers through Azure VNet and configured best practices for security and performance across the application stack.
