Cloud Databases

A cloud database is a database that has been optimized or built for a virtualized environment, deployed in a hybrid cloud, public cloud, or private cloud. Cloud databases offer the ability to pay for storage capacity and bandwidth on a per-user basis, provide scalability on demand, and deliver high availability. They also give enterprises the opportunity to support business applications in a software-as-a-service (SaaS) deployment.

Types of Cloud Database Deployments

• Public Cloud − Database services hosted on public platforms like AWS, Azure, or Google Cloud.
• Private Cloud − Dedicated cloud infrastructure for a single organization.
• Hybrid Cloud − Combination of public and private cloud environments.

Key Characteristics

• Elastic scaling − Resources adjust automatically based on demand.
• Pay-as-you-go − Organizations only pay for resources they actually use.
• High availability − Built-in redundancy and failover across regions.
• Managed services − Cloud provider handles patching, backups, and maintenance.
