Cloud Computing in Fintech - Scalability and Security in the Digital Era

1. What is Cloud Computing in Fintech?

Cloud computing involves using remote servers hosted on the internet to store, manage, and process data instead of relying on local servers or physical infrastructure. It enables fintech firms to deploy applications, process transactions, and store sensitive data securely in the cloud.

Key Cloud Computing Models:

1. Infrastructure-as-a-Service (IaaS): Provides scalable computing resources like virtual servers and storage.
2. Platform-as-a-Service (PaaS): Offers development tools for building applications without managing infrastructure.
3. Software-as-a-Service (SaaS): Delivers cloud-based applications accessible via web browsers.
