# Use Cases

IONOS Cloud DBaaS MariaDB is a flexible database engine that is a perfect fit for facilitating enterprise-level analytics and solutions to drive online web applications for both individual use and business purposes. Due to its open-source nature, improved performance and MySQL compatibility, it is liked by developers and companies alike.

## Scenario 1: Data warehousing and analytics

### Precondition

The price and overhead of managing voluminous data for businesses and individuals rise as the data increases.

### Solution

MariaDB can be recommended for various instances where extensive data is stored and analyzed. Its high-availability environment ensures minimized downtime and continuous availability of data. Here are some scenarios where it can be implemented:

* **Web Applications:** MariaDB is highly scalable, provides fast and reliable data retrieval, and can support sudden spikes in traffic. Hence, it can be used for web applications as a backend database, because it can handle the data storage needs of a dynamic website or web application.
* **Healthcare Systems:** It is ideally suited for the secure and scalable storage and management of healthcare information, medical records, and patient data.
* **E-commerce Organizations:** With its ability to manage user accounts, transactional data, and product catalogs, it is an ideal match for e-commerce platforms. Its ACID compliance ensures integrity and data consistency.

## Scenario 2: Corrupted data cluster

### Precondition

Restoring data to its previous state manually can become a tedious and time-consuming task.

### Solution

The self-restore feature for MariaDB in IONOS Cloud DBaaS can be beneficial in various use cases where data recovery or restoration to a specific point in time is necessary. You can restore a MariaDB cluster from the backup via the [<mark style="color:blue;">DCD</mark>](https://docs.ionos.com/sections-test/guides/databases/mariadb/dcd-how-tos/restore-mariadb-cluster-from-backup) or using the [<mark style="color:blue;">APIs</mark>](https://docs.ionos.com/sections-test/guides/databases/mariadb/api-howtos/restore-mariadb-cluster-from-backup).\
Here are some common use cases:

* **Accidental Data Deletion:** In situations where critical data is accidentally deleted from the MariaDB cluster, the self-restore feature enables you to roll back the cluster to a point before the deletion occurs, helping to recover lost data effectively.
* **Data Corruption:** If the MariaDB cluster experiences data corruption due to software issues or hardware failures, the self-restore feature allows you to restore the cluster to a consistent state before the corruption, ensuring data integrity and minimizing the impact of the corruption.
* **Human Errors:** Mistakes made during operations such as incorrect updates or changes can be resolved by using the self-restore feature to revert the cluster to a state where the errors did not exist, preventing potential data inconsistencies.
* **Security Incidents:** In the event of a security breach or unauthorized access that compromises the MariaDB cluster, the self-restore feature can be used to restore the cluster to a secure state before the security incident occurred, protecting sensitive data.
* **Testing and Development:** The self-restore feature can also be useful for testing and development purposes. Developers can create snapshots of the database at different points in time and use the self-restore feature to easily revert to specific states for testing new features or debugging code.
* **Compliance and Auditing:** For regulatory compliance requirements or auditing purposes, the self-restore feature allows users to demonstrate the ability to restore data to a specific point in time, ensuring data retention policies and compliance standards are met.
