Oracle Cloud Infrastructure (OCI) offers a range of integration services that help organizations connect, manage, and automate workflows between different applications and services. These integration services facilitate data transfer, communication, and coordination across the cloud infrastructure. Here are some key OCI integration services:

1. Oracle Integration Cloud (OIC): Oracle Integration Cloud is a comprehensive integration platform that enables organizations to integrate cloud and on-premises applications, automate business processes, and create customized integrations. It supports various integration styles, including application integration, process automation, and mobile application development.
2. Oracle Cloud Integration Adapters: OCI provides a set of pre-built integration adapters that simplify the connectivity between Oracle Cloud services and third-party applications and systems. These adapters cover a wide range of services, databases, and protocols.
3. Oracle Data Integration Services: OCI offers data integration services that help organizations move, transform, and analyze data across different data sources and targets. This includes services for data replication, data migration, and data transformation.
4. Oracle Messaging Service (OMS): OMS is a managed messaging service that allows applications and microservices to communicate asynchronously. It supports publish-subscribe and point-to-point messaging patterns and can be used to build event-driven architectures.
5. Oracle Event Hub (Streaming): Oracle Event Hub is a fully managed streaming service based on Apache Kafka. It enables real-time data streaming and event processing, making it suitable for applications that require low-latency data ingestion and analysis.
6. Oracle API Gateway: Oracle API Gateway provides security and management features for APIs, allowing organizations to expose and protect their APIs to internal and external consumers. It includes features like authentication, authorization, rate limiting, and API analytics.
7. Oracle Functions: Oracle Functions is a serverless compute service that enables the deployment of event-driven, serverless functions in response to events and triggers. It can be used for building serverless applications and automating tasks.
8. Oracle Cloud Events: Oracle Cloud Events is a service that allows you to create and manage events and triggers for serverless functions and other event-driven workflows. It provides a way to react to changes and events in your OCI environment.
9. Oracle Data Flow: Oracle Data Flow is a serverless Apache Spark service that enables data processing and analytics at scale. It can be used to analyze large datasets and run data processing jobs.
10. Oracle Functions and Application Development: OCI provides tools and services for developing, deploying, and managing applications, including serverless functions, containers, and traditional applications. This includes support for popular development languages and frameworks.
