Regulations that prevent moving data into the public cloud and putting data in the cloud would break data residency rules are two typical reasons why customers cannot move their database into the public cloud. Some organizations may have legal, compliance, or business policy requirements that restrict where their data can be stored or processed. For example, some regulations may require that data be stored within a certain country or region, or that data be encrypted or anonymized before being transferred to the cloud. Moving data to the public cloud may violate these regulations or introduce additional risks or costs for the customers.

Security and support compliance are two important reasons to upgrade and patch your Oracle Database. According to the Oracle blog3, "Security is one of the most important reasons to patch your database. Every quarter Oracle releases security patches as part of the Critical Patch Update (CPU) program. These patches fix vulnerabilities in the database software that could be exploited by malicious attackers." Additionally, according to the Oracle blog4, "Support compliance is another reason to patch your database. Oracle provides different levels of support for different versions of the database software. To be eligible for certain support services, such as Extended Support or Sustaining Support, you need to apply the latest patches available for your version."

These are three options that can be selected when using the console to create an autonomous database on an Autonomous Exadata Cloud@Customer. According to the Oracle documentation1, "When you create an Autonomous Database on Autonomous Exadata Cloud@Customer, you specify the following information: Database name, Database display name, Workload type, Admin password, License type, Number of OCPUs, Storage (TB), and Tags (optional)." The workload type can be either transaction processing or data warehouse.

This statement is true about how the Converged Database helps to access data using an API. According to the Oracle documentation5, "Oracle REST Data Services (ORDS) makes it easy to develop modern REST interfaces for relational data in the Oracle Database and the Oracle Database 18c JSON Document Store. A mid-tier Java application, ORDS maps HTTP(S) verbs (GET, POST, PUT, DELETE, etc.) to database transactions and returns any results formatted using JSON." ORDS can automatically generate RESTful services for tables and views in the database or expose custom REST APIs using SQL or PL/SQL.
