What Are Cloud Computing Applications?

Cloud computing applications are software solutions delivered over the internet from centralized data centers managed by third-party providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Unlike traditional software installed on local machines, cloud applications:

• Run on remote infrastructure (servers, storage, networks) maintained by cloud providers.
• Scale dynamically based on demand without manual hardware provisioning.
• Enable multi-device access from anywhere with an internet connection.
• Receive automatic updates without requiring user intervention.

Cloud-Native vs Cloud-Enabled Applications

• Cloud-native applications are built specifically for cloud environments using microservices, containers, and serverless architectures (e.g., Netflix, Uber).
• Cloud-enabled applications are traditional software adapted to run in the cloud, often retaining legacy architecture (e.g., migrated ERP systems).

Understanding this distinction matters for performance optimization, scalability, and cost management—cloud-native apps leverage cloud benefits more fully.
