In this blog, I have covered a High-level Overview of Exadata Cloud Service (ExaCS).
Not every company can own and staff a data center; there is a lot involved. So where can you turn if you need the highest-performing and most available infrastructure for running Oracle Database? There is a Service Exadata Cloud Service that gives a solution to the problem.
Topics that we’ll cover in this blog:
- Exadata Cloud Service(ExaCS)
- ExaCS Supported Database Edition & Versions
- Lifecycle Management(ExaCS)
- Why choose Exadata Cloud Service?
- Exadata Cloud Service Typical Deployment Flow
- Best Practices for Exadata Cloud Service Instances
Exadata Cloud Service(ExaCS)
Oracle Exadata Cloud Service is the best place for customers to run Oracle Database workloads in the cloud. Dedicated X8M infrastructure is isolated from other users, allowing database teams to improve security, performance, and uptime for customer databases.
Scalable architecture with up to 1,600 OCPUs and 2.5 PB uncompressed databases enables customers to run any type and size of enterprise database workload in Oracle Cloud Infrastructure. Flexible licensing options and non-disruptive up-and-down scaling of compute resources allow customers to quickly adjust OCPU consumption to match workload demands, lowering costs with pay-per-use economics.

Why choose Exadata Cloud Service?
- Exadata within Oracle Cloud Service provides a set of unique values around Availability, Performance, and ease of cloud integration.
- Exadata offering private and secure networking a dedicated network with multi-layered security to ensure data safety.
- Exadata provides a highly available data center, each data center has three Availablity domains for local failover as well as the ability to peer across regions.
- Best-in-class Compute instances combine the Exadata Cloud Service with Bare Metal compute servers for the high-performance application layer.
- Exadata Cloud Service provides secure and high-performance access from on-premises systems using fastconnect & VPN also from within OCI to other oracle cloud services using fast 23 Gb per second connectivity for backing up the database and disaster recovery.
Exadata Cloud Service Typical Deployment Flow
The below points indicate what is the deployment flow of ExaCS.
- Creating a VCN
- Creating Gateways- NAT/IGWand Service Gateway.
- Creating Routing Tables.
- Creating Security Lists
- Creating DHCP Options.
- Creating Subnets.
- Modifying Security Rules.
- Launching Exadata DB System.
Note:– SG can handle all the internal communication including backups, patching within the OCI region. For deploying Exadata Cloud Service in OCI you must have an IAM policy allowing the operation, E.g: Allow group DBAdmins to manage database-family in tenancy.
Best Practices for Exadata Cloud Service Instances
Oracle recommends that you follow these best practice guidelines to ensure the manageability of your Exadata Cloud Service instance:
- Wherever possible, use the Oracle-supplied cloud interfaces such as the Oracle Cloud Infrastructure Console, API, or CLI, or cloud-specific tools such as
dbaasclianddbaasapito perform lifecycle management and administrative operations on your Exadata Cloud Service instance. - Do not change the compute node OS users or manually manipulate SSH key settings associated with your Exadata DB system.
- Apply only patches that are available through the Database service. Do not apply patches from any other source unless you are directed to do so by Oracle Support.
- Apply the quarterly patches regularly, every quarter if possible.
- Do not change the ports for Oracle Net Listener.
