App Engine (Platform as a Service)

Imagine you built a web app

Now you want to launch it online… but you get stuck in:

• Server setup
• Scaling issues
• Maintenance headaches

Instead of managing all this, you simply upload your code…

And it runs automatically
Scales when users increase
No server management needed

That’s the magic of App Engine

What is App Engine?

App Engine is a Platform as a Service (PaaS) in Google Cloud that allows you to:

• Build and deploy applications
• Without managing servers

You focus only on code, GCP handles the rest

Key Features of App Engine

• No Server Management → Fully managed platform
• Automatic Scaling → Handles traffic automatically
• Built-in Security → Secure by default
• Multiple Languages Support → Python, Java, Node.js, etc.
• Version Control → Deploy different versions easily

App Engine vs Compute Engine
