Oracle Databases for Containers and Kubernetes
Oracle offers convenient, containerized images (Podman and Docker) for a single instance, sharded, and Oracle Real Application Clusters (Oracle RAC) databases running on single or multiple hosts, reducing deployment and management work. Oracle’s database operator on Kubernetes automates the lifecycle management of Oracle Databases by extending Kubernetes APIs.
Oracle introduces integrated vector database to augment generative AI and dramatically increase developer productivity
New AI vector similarity search in Oracle Database 23c allows the combination of search in semantic and business data to provide highly accurate answers quickly and securely.
Oracle Databases for Containers and Kubernetes features
Containerized Databases on Kubernetes
Kubernetes provides orchestration for rapid provisioning of containerized Oracle Databases. Kubernetes supports faster deployments through prebuilt configurations, self-monitoring, and elasticity.
Containerized Databases
Containerized images can be consumed with minimal effort and deployed in the cloud and on-premises environments.
Oracle Database Operator for Kubernetes
Oracle Database offers the Kubernetes API software extensions with custom resource definitions and controllers for automating operations and lifecycle management of databases deployed within and outside Kubernetes clusters.
Accelerate development and testing
Quickly provision databases for development and testing using prebuilt images, accelerating delivery of cloud or on-premises applications.
Consolidate databases
Reduce infrastructure costs and complexity by running more database containers on fewer servers.
Portability
Run containerized Oracle Databases across on-premises and cloud quickly and consistently.
Scalability
Add multiple containers to efficiently create more instances of Oracle Database, running only the number of containers required to support database workloads.
Runtime environments for Docker and Podman
| Container images | Docker (OL7) | Podman (OL8) |
|---|---|---|
| Single instance database (includes SE, EE, XE and Oracle Database 23c Free) | 19.16c, 21.3c | 19.3c, 21.3c |
| Sharded Database | 19.16c, 21.3c | 19.3c, 21.3c |
| Real Application Clusters (RAC) | 19.16c, 21.3c | 19.16c, 21.7c |
Orchestration of infrastructure for database deployment
Leverage Oracle Database containerized images to automate deployment and integration with your IT infrastructure.
Monitoring of infrastructure resources
Monitor resources to maintain the high availability of application states and scale or descale database pods based on your workload requirements.
Runtime environments for Kubernetes
| Container images | Oracle Container Engine for Kubernetes and Oracle Cloud Native Environment |
|---|---|
| Single instance Database (includes XE, SE, and EE) | 19.3c, 21.3c |
| Sharded Database | 19.3c, 21.3c |
Automation of database management
Oracle Database Operator for Kubernetes (OraOperator) helps developers, DBAs, DevOps, and GitOps teams reduce the time and complexity of deploying and managing Oracle Databases. It eliminates the dependency on a human operator or administrator for most database operations.
Kubernetes APIs extended for database lifecycle management and deployment
Oracle Database is natively part of the Kubernetes infrastructure to start, stop, monitor, patch, upgrade, and perform other lifecycle management operations from Kubernetes. It provides these capabilities whether your Oracle Database is in the cloud, on-premises, or in Kubernetes.
