Five Big Reasons to Run Oracle Database on Oracle Cloud Infrastructure

Oracle built its reputation on the power of the world's first commercially available relational database technology. Today, Oracle Database technologies are the number-one choice for enterprise database workloads—and Oracle Cloud Infrastructure is the best public cloud for running Oracle Database offerings.

That's partly because the underlying architecture of Oracle Cloud Infrastructure was designed with the optimal performance of Oracle Database in mind. But it also has to do with the powerful capabilities built directly into our database technology.

Here are five important reasons why Oracle Cloud Infrastructure is the right choice for companies that want to run Oracle Database technologies in the cloud.

Superior Database and Application Performance

The networking architecture of Oracle Cloud Infrastructure is designed to support optimal performance of Oracle Database and the applications that depend on it. We accomplish this by using direct, point-to-point connections between compute and database instances running within Oracle Cloud Infrastructure. These point-to-point connections translate to low latency and superior application performance.

In addition to superior performance, users of Oracle Database on Oracle Cloud Infrastructure also benefit from predictable performance. They get dedicated servers with a defined shape and networking architecture, so they always know what they're getting in terms of performance. This approach also ensures that "noisy neighbors" don't negatively impact performance.

Tight Security, Private Networking

Oracle Database technologies on Oracle Cloud Infrastructure provide unmatched levels of privacy and security because database systems are deployed into a virtual cloud network (VCN) by default.

A VCN is a customizable and completely private network that gives users full control over the networking environment. Users can assign their own private IP address space, create subnets, create route tables, and configure stateful firewalls. Users can also configure inbound and outbound security lists to protect against malicious users accessing DB systems. A single tenant can have multiple VCNs, and databases can be deployed into private subnets with no public IP address, said Sebastian Solbach, an Oracle Database expert and technical consultant with Oracle Cloud Infrastructure.

"When you spin up a database instance in most clouds today, it will take a maximum of five minutes before the first hacker tries to access your system if it has a public IP address," Solbach said. "Oracle Cloud Infrastructure allows databases to run in a totally private subnet without any public networking access to these database instances."

Real Application Clusters

Oracle is the only cloud provider that offers the power of Oracle Real Application Clusters (RAC).

Oracle RAC gives users the highest level of database availability by removing individual database servers as a single point of failure. In a clustered environment, the database itself is shared across a pool of servers, which means that if any server in the pool fails, the database continues to run on surviving servers. In Oracle Cloud Infrastructure, users run Oracle RAC on virtual machines (VMs) within a VCN.

"Oracle RAC requires two things, and the first thing is shared storage. Oracle is the only cloud provider that officially offers shared block storage between instances in the cloud," Solbach said. "Oracle RAC also has networking requirements that can only be met by Oracle Cloud Infrastructure today."


Oracle Database Exadata Cloud Service combines the best database with the best cloud platform. Exadata has proven itself at thousands of mission-critical deployments at leading banks, airlines, telecommunications companies, stock exchanges, government agencies, and ecommerce sites.

Oracle Database Exadata Cloud Machines are optimized for performance and run in the same VCN as your VMs and bare metal server instances. Exadata supports Oracle RAC for highly available databases. Users can also configure Exadata in multiple availability domains with Oracle Active Data Guard for even higher availability. Oracle Active Data Guard eliminates single points of failure by maintaining synchronized physical replicas of production databases at a remote location.

"Oracle Exadata is our most powerful database server offering," Solbach said. "Oracle Exadata is the place to run data warehouse workloads. It's also a very robust platform for running (Online Transaction Processing) workloads."

One Point of Contact

Fewer phone calls. Less hassle. Top-notch support. Users who run Oracle Database technologies in Oracle Cloud Infrastructure save time and increase efficiency by having a single point of contact for support when questions or problems arise.

“If you're running in another cloud provider and you experience an issue with Oracle Database, you have to contact Oracle. If you have a problem with the underlying infrastructure, you have to contact that cloud provider,” Solbach said. "With Oracle Database on Oracle Cloud Infrastructure, you get a single point of contact who understands Oracle technologies better than anyone else."
