Deploying a Full PaaS Architecture in Azure with Just a Bash Script

Deploying a Full PaaS Architecture in Azure with Just a Bash Script

In modern cloud development, time is of the essence. Whether you're launching APIs, scaling SaaS platforms, or building microservices, Platform as a Service (PaaS) simplifies the infrastructure layer so you can focus on what matters most—your application.

In this post, we’ll walk through a real-world Azure PaaS use case using just a few lines of Azure CLI and Bash scripting. We'll provision a resource group, a Cosmos DB instance, a SQL Server, and deploy a Web App—all automated and production-ready.

Real-World Use Case: Rapid Prototyping for Multi-Tier Cloud Apps

Imagine a full-stack developer is building a modern app with a NoSQL document store (Cosmos DB), a relational backend (SQL Server), and a front-end running on Azure Web Apps. The goal: set it up in under 5 minutes using PaaS building blocks.

The Azure CLI Automation Script

#!/bin/bash

# Create a resource group
az group create -l eastus2 -n GrupoRecursosPaaS

# Create a Cosmos DB instance
az cosmosdb create --name cosmospaas123 --resource-group GrupoRecursosPaaS

# Deploy an Azure SQL Server
az sql server create -l eastus2 -g GrupoRecursosPaaS -n serverPaas006 -u aminespinoza -p Am0_Apr3nd3r$

# Create an App Service Plan
az appservice plan create -g GrupoRecursosPaaS -n aminWebPlan --sku B1 --is-linux

# Deploy a Web App
az webapp create -g GrupoRecursosPaaS -p aminWebPlan -n aminespinozaweb --runtime "NODE|18-lts"

# Optional Cleanup
az group delete -n GrupoRecursosPaaS

Key Components Explained

Benefits of Using PaaS

✅ No server management

✅ Auto-scaling & high availability

✅ Built-in security & patching

✅ Easy integration with Azure DevOps/GitHub

✅ Cost-effective for prototypes and microservices

Extend This Use Case

Take your automation to the next level:

• Deploy from GitHub: Add az webapp deployment source config
• Secure with Managed Identities
• Use Bicep for declarative deployments
• Integrate Azure Cognitive Search or OpenAI

Final Thoughts

This script turns you from cloud operator to cloud orchestrator. With just a few CLI commands, you've built a scalable, modular, production-aligned architecture using Azure PaaS services. No infrastructure headaches. No over-engineering.
