Cloud Native Applications inherently take advantage of continuous integration and continuous delivery (CI/CD) to ensure rapid development, testing, and deployment cycles. This approach allows for faster iteration, scaling, and maintenance of the application, which is a fundamental characteristic of Cloud Native applications.

NoSQL databases provide flexible schemas for the storage and retrieval of data beyond the traditional table structures used in relational databases. Unlike relational databases, which use fixed schemas and structured query language (SQL) for defining and manipulating data, NoSQL databases can store unstructured or semi-structured data, making them an ideal choice for applications that require flexibility and scalability.

IBM Cloud Backup is the automated agent-based backup system available in IBM Cloud. It provides robust, scalable, and secure data protection offering within the IBM Cloud infrastructure, ensuring that data is backed up and recoverable across various IBM Cloud data centers worldwide.

The General Data Protection Regulation (GDPR) is a comprehensive data privacy regulation implemented in the European Union.
