INTEGRATION? IT’S JUST ABOUT BOXES AND LINES!
Goals:
¢ Enabling systems to talk to each other
¢ Ensure that data is where it is needed when it is needed in the form in which it is needed

¢ Single execution process
¢ Shared database
¢ Local, app-internal communication only
¢ Multiple Deployment units
¢ Exclusive execution process per service
¢ Database per Service (usually)
¢ Remote, inter-service communication

SERVICE INTEGRATION
DILEMMA
• Amount of traffic
• Number of services
• Teams autonomity
Reliability
¢ Traffic connectivity & reliability
¢ Zero-trust security
¢ Observability

ARCHITECTURE

Öffentlich
HOW WE BUILT INTEGRATION SO FAR
¢ Monolithic architecture
¢ Often classic JEE deployments
¢ Integrations share single execution process
¢ Limited freedom of technology choice
¢ Core component:
¢ ESB Platform (Oracle Service Bus, Sonic ESB)
¢ Reverse Proxy for handling external traffic
¢ Focus on horizontal integration challenges

Öffentlich
HOW WE CAN BUILD INTEGRATION TODAY
¢ Cloud-native architecture, by using e.g.
¢ Containerization
¢ Kubernetes as Core runtime platform
¢ Single execution process per integration
¢ Core components:
¢ Distributed, lightweight ESB
¢ Event Hub for async integration
¢ API Gateway for sync integration
¢ Focus on horizontal as well as vertical
integration challenges

ORACLE INTEGRATION CLOUD (OIC)
¢ Low/No-Code Integration Platform as a Service (iPaaS) offering, providing
¢ Adapters to SaaS, On-prem Enterprise applications and wiede range of further adapters (e.g. RPA)
¢ Process Automation capabilities (Dynamic / Static Processes)
¢ Integration Insights
¢ Visual Builder for web and mobile applications
¢ Offers pre-built integrations to accelarate integration development
¢ Don’t need to care on the underlying platform, just focus on integrating your applications
¢ Main focus: Application-centric and Process-centric integration

Öffentlich
OCI DATA INTEGRATION (OCIDI)
¢ No-code solution for designing data flows
¢ Ingest data from various data sources
¢ Transform and load data into a data lake or data warehouse
¢ Reusable templates and dataflows
¢ Hybrid data execution to provide most efficient way to extract, transform and load data
¢ Automatic ETL or E-LT method selection
¢ Pushdown E-LT to eliminate performance degradation on data sources
¢ PAYG pricing allows to deal with data integration scenarios cost efficient way

Öffentlich
OCI GOLDENGATE
¢ Real-time data mesh solution
¢ Uses data replication
¢ E2E Monitoring
¢ Provides transactional integrity and secure data delivery (SSL & encryption)
¢ Dynamic scaling as needed (no need to allocate explicit Compute resources)
¢ Supports a variety of data sources and sinks including Multi-Cloud and Big Data support
¢ Allows for real-time streaming and analysis

INTEGRATION PLATFORM WITH OCI CLOUD-NATIVE SERVICES
¢ Industry standards-based approach
¢ Open API
¢ Kafka (OCI Streaming)
¢ Container / Kubernetes
¢ Open Tracing / Open Metrics
¢ Development Platform also provided by OCI
¢ OCI Container Registry / Artifact Registry
¢ OCI DevOps
¢ Monitoring can be done with OCI Monitoring,
OCI Logging and OCI APM (needs to be
explicitly setup!)

Öffentlich
CHARACTERISTICS OF OCI CLOUD-NATIVE APPROACH
¢ Developer-centric, Cloud-agnostic approach
¢ Supports Hybrid, On-prem and Cloud-only deployment scenario
¢ No specific Know-How - Toolset, technologies and processes developers are familiar with
¢ Operational and management responsibility for Platform team
¢ Integration scenarios covered:
¢ SaaS integration

Öffentlich
INTEGRATION PLATFORM BASED ON OIC
¢ iPaaS-based solution
¢ No-/Low-Code solution
¢ Pre-built Adpater Services allow easy access
¢ Development platform provided by OIC
(Cloud-based Drag ‘n Drop)
¢ Easy and secure On-prem integration using
OIC Connectivity agents
¢ Monitoring of infrastructure is done by Oracle
¢ (Business) Monitoring of integration flows can
be done using Integration Insights

Öffentlich
CHARACTERISTICS OF OIC APPROACH
¢ Less Development, more Business-centric approach
¢ Vendor lock-in (which is not bad by default, but people should be aware of it)
¢ Supports Cloud-only deployment scenario (iPaaS approach)
¢ Specific Know-How, Toolset and Processes needed
¢ Less operational and management responsibility for Platform team
¢ SaaS integration

Öffentlich
COMBINED APPROACH IS ALSO AN OPTION

Öffentlich
CHARACTERISTICS OF OIC APPROACH
¢ Best of the the two worlds
¢ OIC particularly used for SaaS connectivity
¢ SaaS integration
¢ Note: To also cover Data ingestion Use cases more efficiently, OCI GoldenGate or OICDI can be
used

¢ There’s no one size fits all recipe!
¢ Questions you should ask (of course there are
more):
¢ What is the integration focus?
¢ What are the integration scenarios?
¢ Which architectural requirements do I have?
¢ What about NFR?
¢ Which skills do my team(s) have?
¢ Answering these questions will give you hints
which tools to choose from your toolbox
WHEN TO USE WHICH SERVICES?
