Oracle Exadata Cloud Service: The Best OCI Database Option
Oracle provides various database services that help customers to use the database in an efficient way and meet their requirements. One of the best options is Oracle Exadata Cloud Service, which is part of Oracle Cloud Infrastructure (OCI).
Overview of Oracle Exadata Cloud Service
Oracle Exadata Cloud Service is a cloud database service providing high performance, mission-critical data resilience, and modern cloud-based architecture. It is the only cloud platform that can consolidate all your data management workloads into a single cloud platform and it can handle up to 368 CPUs, 5.62 terabytes of RAM, over 150 TB of Flash, and 340 TB of database file storage. It also features state-of-the-art PCI Flash for complete isolation of tenants with no overprovisioning.
Benefits of Oracle Exadata Cloud Service
Oracle Exadata Cloud Service provides several benefits, such as:
Elastic Web-driven Provisioning: Oracle experts manage all back-end infrastructure on behalf of customers, reducing human resources and IT administration costs, allowing IT to focus on improving business results.
Expandability: Customers can run larger databases and multiple workloads separately, allowing them to fulfill their requirements.
Easy to Use: The deep learning algorithms used by Oracle allow developers to make better performance applications with no integration with other services outside the database.
Low Costs: Customers can run analytics workloads at low cost, meeting their desired requirements with few resources.
Flexible Licensing and Scaling: Customers can fix OCPU (Oracle Cloud Processing Units) usage in order to match workload demands while keeping costs low.
Conclusion
Oracle Exadata Cloud Service provides high performance, mission-critical data resilience, and modern cloud-based architecture. It features elastic web-driven provisioning, expandability, ease of use, low costs, and flexible licensing and scaling of resources. This makes it an ideal choice for customers looking for a cloud database service.

Oracle Exadata Cloud Service is the perfect option for customers who need an efficient and secure database solution. It provides a reliable, secure, and user-friendly interface for managing databases.
#Exadata Cloud Service Instance
##Computer Node Configuration
A Virtual Machine is used to configure each computer node in an Exadata Cloud Service instance. As the root user, you have full control over the computer node virtual machines and can download and run additional software.
Administrative Access
You do not have administrative access to the underlying Exadata infrastructure components like the physical computer node hardware, the network switch, the power distribution unit (PDU), the integrated light-off management interface (ILOM), or the Exadata Host.
Database Privileges
You have full administrative privileges over your database, and can connect to it using Oracle Net Services from outside the Oracle Cloud Infrastructure. You can the default automatic maintenance settings and control the recovery process in the event of a database failure.
Exadata System Configuration
Exadata Cloud Service configurations offer a range of processing power, memory, storage, and network resources that can be scaled to meet your workload demands. There are three Exadata Cloud Service configurations available – Quarter Rack, Half Rack, and Full Rack – each offering an increasing number of compute and storage nodes.
Quarter Rack Configuration
This configuration offers two compute nodes and three storage servers. Each compute node should include an equal number of valid CPU cores.
Half Rack Configuration
This configuration offers four compute nodes and six storage servers. Each compute node should include an equal number of valid CPU cores.
Full Rack Configuration
This configuration offers eight compute nodes and 12 storage servers. Each compute node should include an equal number of valid CPU cores.
Exadata Storage Configuration Overview
Exadata Cloud Service in Oracle Cloud Infrastructure provides a unique set of features that ensure high performance, availability, and simplified cloud integration. With Exadata, users can access a secure and private network, as well as a highly available data center with a multi-layered security system. Each data center comes with three availability domains for local failover and cross-regional peering.
Oracle Exadata X6 & X5 Hardware Disk Groups
In cases based on Oracle Exadata X6 and X5 hardware, additional disk groups are used to support different operations. The DBFS disk group is typically used to store Oracle Clusterware files such as the Oracle Cluster Registry and voting disks. The ACFS disk group is used to store shared file systems, which contain software binaries and files related to cloud tools installed on Exadata Cloud Service nodes. It is important to note that data files and backups should not be stored in disk system groups or ACFS file systems.
Oracle Exadata X7 Hardware
In Oracle Exadata X7 hardware cases, no other system disk groups are available. Instead, a limited space is allocated to the INFO disk group to support shared file systems that store software binaries, patches, and files related to cloud tools. As with X6 and X5 hardware, it is important to ensure that data files and backups are not stored in the ACFS system-related systems.
Storage Space Management
The storage space in Exadata Storage Servers is managed by Oracle Automatic Storage Management (ASM). When configured, the following disk groups are created:
• DATA disk group – used for storing database data files
• RECO disk group – used for storing the Fast Recovery Area
Database Administration Control:
Full Control for Database Administrators
What They Can Do
Database administrators have full control over the database structure. They can create, delete, and modify the database structure as needed. They can also restore the database or backup the database in the cloud. Furthermore, database administrators are responsible for monitoring and controlling the services used in the cloud. This includes managing users, setting up security, and ensuring performance is optimized.
Security Features of Oracle Exadata Cloud Service
Always-On Encryption:
Oracle Exadata Cloud Service provides always-on encryption to protect customer information from unauthorized access. It also includes advanced security features such as privileged access controls, monitoring, and limiting access to databases.
Audit Vault:
The Audit Vault continuously monitors database traffic for threats and helps customers mitigate risks.
Data Safe:
Data Safe enables customers to identify, store, and disable important data for other uses.
Certifications:
Oracle Exadata Cloud Service is certified as a commercial, dedicated region, allowing customers to further secure their database environment.
Data Guard:
Oracle Database Service provides mission-critical systems such as RAC, Bare Metal, and VMs to meet customer needs. It also offers Data Guard, a robust system that supports other Oracle database options and maintains synchronization between the primary and standby databases. It features two modes of operation – Switchover (planned migration with no data loss) and Failover (unplanned migration with minimal data loss).
BYOL Model:
Oracle Database Service also supports Bring Your Own License (BYOL) model for customers looking for complete provisioning, patching, backup, and other features.
