—You have to install this software yourself, and you are responsible for all maintenance operations for this software. You have root privilege, so you can load and run software in the compute environment. You have full administrative privileges for the Oracle database.a compute environment with pre-installed virtual machine images that include all software needed to create and run an Oracle Database. You connect to the virtual machine and run the Oracle Database Configuration Assistant (DBCA) to create your database. All subsequent maintenance operations, including backup, patching and upgrades, are performed by you.

This level also includes Oracle Database and supporting software. However, the software is installed for you, an Oracle database is created using values you provide when creating the database deployment, and the database is started. Additionally, you can direct Database Cloud Service to set up automatic backups. Finally, the deployment includes cloud tooling that simplifies backup, recovery, patching and upgrade operations. You have root privilege, so you can load and run software in the compute environment.You have full administrative privileges for the Oracle database. You are for making any changes to the automated maintenance setup, and you are responsible for recovery operations in the event of a failure.
When creating a database deployment on Oracle Database Cloud Service, you choose one of the following metering frequencies:
—Pay only for the number of hours used during your billing period.You cannot switch a deployment from hourly to monthly metering frequency after it is created.
—Pay one price for the full month irrespective of the number of hours used.For deployments that are started in the middle of a month, the price is pro-rated;
you pay only for the partial month from the start date
When creating a database deployment on Oracle Database Cloud Service, you choose the computing power for the associated compute node or nodes from a list of supported OCPU (Oracle CPU) and processor RAM combinations. The combinations you can choose from depends on the infrastructure you are creating the deployment in:
– VM.Standard1.1 – 1.0 OCPU, 7.0 GB RAM
– VM.Standard1.2 – 2.0 OCPU, 14.0 GB RAM
– VM.Standard1.4 – 4.0 OCPU, 28.0 GB RAM
– VM.Standard1.8 – 8.0 OCPU, 56.0 GB RAM
– VM.Standard1.16 – 16.0 OCPU, 112.0 GB RAM
– BM.Standard1.32 – 36.0 OCPU, 256.0 GB RAM
Types and combinations of memory type
OC3 to OC7 denotes General purpose computing power.
OC1m to OC5m denotes High memory computing power.
Here is various features in each of these Database Cloud options
A) Standard Edition (SE) —Oracle Database Standard Edition, which delivers database for department-level, and Web applications. It includes all the RDBMS features necessary to build business-critical applications.
B) Enterprise Edition (EE) —Oracle Database Enterprise Edition, includes everything in SE + Database for online transaction processing (OLTP) applications, query-intensive data warehouses, and demanding Internet applications. In simple Terms better then Standard Edition .
C) Enterprise Edition – High Performance (EE-HP) — includes everything in EE all the features of Enterprise Edition, plus partitioning , multi-tenancy, advanced compression, real application testing, advanced Security, Label Security, Database Vault, Spatial & Graph, Data Masking, and management packs.
D)Enterprise Edition – Extreme Performance-provides all the features of Enterprise Edition High Performance, plus In-Memory, Active Data Guard and RAC .
So If you need RAC Database or Active Data Guard features then select Enterprise Edition Extreme Performance (EE-EP) option.
