What are the 4 layers of cloud architecture?

The four key layers of cloud architecture are:

1. Infrastructure Layer – Includes virtual machines, storage, and networking resources.
   
2. Platform Layer – Offers middleware and development tools like databases and serverless computing.
   
3. Application Layer – Contains end-user applications, including SaaS tools and APIs.
   
4. Security and Management Layer – Covers identity access management, compliance, and monitoring tools.
   
   

For effective data engineering services, these layers must work in harmony to support secure, scalable data operations. A specialized data engineering company ensures your architecture is built with cloud best practices, allowing for high availability and resilience.
