About Java Cloud Service Instances in Oracle Cloud Infrastructure

You can create Oracle Java Cloud Service instances in Oracle Cloud Infrastructure and in Oracle Cloud Infrastructure Classic.

Workflow for Creating an Instance in Oracle Cloud Infrastructure

Task More Information
Task 1: Understand the differences between instances created in Oracle Cloud Infrastructure and in Oracle Cloud Infrastructure Classic. Differences Between Instances in Oracle Cloud Infrastructure and Oracle Cloud Infrastructure Classic
Task 2: Create the required network, storage, and security resources in Oracle Cloud Infrastructure.
Task 3: Create an Oracle Database Cloud Service deployment.

Note: The Oracle Database Cloud Service deployment that you intend to associate with your Oracle Java Cloud Service instance can be on a different subnet, but it must be in the same region and VCN.

Task 4: Create the Oracle Java Cloud Service instance.

Differences Between Instances in Oracle Cloud Infrastructure and Oracle Cloud Infrastructure Classic

The Oracle WebLogic Server environment that your Oracle Java Cloud Service instance provides in either type of infrastructure is substantially the same. A few differences exist in the underlying infrastructure components and in the supported capabilities. Knowing these differences will help you select an appropriate region while creating your Oracle Java Cloud Service instance.

Feature Oracle Cloud Infrastructure Classic Oracle Cloud Infrastructure
Availability domains Not applicable Each region has multiple isolated availability domains, with separate power and cooling. The availability domains within a region are interconnected using a low-latency network. When creating an instance, you can select the availability domain that the instance should be placed in.

Compute shapes Standard and high memory shapes

Note: The list of available shapes may vary by region.

VM.Standard and BM.Standard shapes

Note: The list of available shapes may vary by region.

Networking You can attach instances to IP networks defined in Oracle Cloud Infrastructure Compute Classic. You must attach each instance to a subnet, in a virtual cloud network created in Oracle Cloud Infrastructure.

Reserving public IP addresses Supported Not supported

Scaling the shape of a node Supported Not supported

Autoscaling a cluster Supported Not supported

Adding block storage You can perform the add-storage operation up to 6 times for a node. In each operation, you can add from 1 to 2048 GB. You can perform the add-storage operation up to 29 times for a node. In each operation, you can add 50 GB or a multiple of 50.

Creating snapshots and clones Supported Not supported

Managing access rules Use the Oracle Java Cloud Service interfaces to configure access rules. Configure security rules in the Oracle Cloud Infrastructure interfaces.

Using Oracle Identity Cloud Service to control access to applications deployed on the instance In accounts that use Oracle Identity Cloud Service, while creating an instance, you can enable Oracle Identity Cloud Service as the identity provider for applications deployed on the instance.

Not supported
Load balancer options While creating an instance, if you enable Oracle Identity Cloud Service as the identity provider, an Oracle-managed load balancer is created and configured automatically for the instance.

If you don’t enable Oracle Identity Cloud Service, then you can use Oracle Traffic Director.

Oracle Traffic Director
Object storage for backups You can create the object storage container either before or during instance creation. You must create the object storage bucket in Oracle Cloud Infrastructure before creating the instance.

Virtual Image service level

Supported Not supported
Associating an instance with a RAC database deployment of Oracle Database Cloud Service

Supported Not supported
Changing the database association for an instance After creating an instance, you can change the infrastructure database (Oracle Database Cloud Service deployment) that the instance is associated with. Not supported
