MOTIVATION
01

¢ Fast time to market is becoming more and more important
¢ Classic software development shows how it's done
¢ CI/CD, Containerization, high degree of automation
¢ Departments are often unhappy because the BI-Team
cannot keep up with the implementation
¢ Departments want self-service offers
¢ Important to avoid „shadow IT“
¢ Faster time to market through decentralization of systems
¢ Data Platform vs. Integration Platform
¢ Grows together more and more
NEW WORLD PROBLEMS
ANALYTICS
MODERN

¢ Decentralization requires more governance
¢ Metrics & Logging
¢ Access permissions & policies
¢ Metadata
¢ API-Management can help to implement these solutions
¢ Creates standardization
¢ Avoids duplicate development efforts
¢ A high degree of automation can help to control decentralized
systems
¢ Self service platform & ready to use components
¢ Development templetes for recurring tasks
SECURITY & OBERSERVABILITY
SECURITY
OBSERVABILITY

WHY DO INTEGRATION AND
ANALYTICS BELONG TOGETHER?
02

INTERFACES IN ANALYTICS
Analytics meets Integration – Modern Development mit Data APIs
¢ Classic „API“ in the form of
direct database access
¢ Database Link, Views, etc.
¢ Database authentication and
authorization is used
¢ Missing standardization and
documentation
¢ Consumer usually has to
deal with the JDBC protocol
7

TRADITIONAL VS. CLOUD-NATIVE SYSTEMS
¢ Single Deployment unit
¢ 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
UI
Business
Logic
Persistence

ACHIEVE LOOSE COUPLING THROUGH API DESIGN-FIRST APPROACH
¢ Synchronous APIs (it’s not just REST!)
¢ REST (OpenAPI)
¢ GraphQL
¢ gRPC
¢ Asynchronous APIs (preferred)
¢ Async API
¢ Data description with
¢ Protobuf
¢ Avro
¢ JSON Schema

APIS SHOULD DELIVER BUSINESS VALUE!
¢ Focus on potential consumers
¢ How will a consumer use my API?
¢ What kind of resources and operations are
needed by the consumers?
¢ …
¢ APIs should be consumer-centric and thus
be consumable
¢ Well-designed, secured and compliant
¢ Documented, discoverable and accessible
¢ Performant, reliable and scalable
Source: https://konghq.com/blog/what-is-apiops/
Compliant
Functional Findable
The intersection of the three
characteristics defines
consumable APIs!

BUSINESS DOMAINS
¢ Domain Driven Design (DDD) as a basis
¢ Loose coupling between systems
¢ Changes to modules should have as little
impact as possible on other modules
¢ Puts domain at the center of modeling /
architectural work
¢ Often in the microservice environment -
classic software development
¢ Domain
¢ Depicts the technicality / technical logic
of a business area
¢ HR department, CRM department, SCM, etc.

MODERNIZATION WITH DATA APIS
¢ Existing interfaces are expanded with "real" API services
¢ Contract defined in API-Specification
¢ Overview of the available APIs in central developer portal
¢ Other services can reuse the new API
¢ Flexible platforms such as Kubernetes can be used

CUSTOMER SCENARIO: SDLC

DEMO

DEMO: ARCHITECTURE & DATA MODEL

DEMO PLATFORM: ORACLE CONTAINER ENGINE FOR KUBERNETES
(OKE)
Based on IaaS Oracle
Compute Cloud Service
Worker Nodes: VM
Master Node:
•Managed and maintained by Oracle
•Not visible for the end user
•Master nodes are free of charge
Auto-scaling capabilities
using Worker-Node Pools
Can be provisioned using
OCI Cloud Console
OCI Cloud Shell
OCI CLI
Terraform (OCI Resource Manager)

DEMO PLATFORM: CONTAINER REGISTRY
¢ Open standards-based, Oracle-managed Docker registry service for securely storing and
sharing container images (Docker v2 compliant)
¢ Data protection through integration with OCI object storage
¢ Automatic clean up old docker images (Retention policies)
¢ Integrates with different OCI services and 3rd party DevOps and dev tools (Jenkins, Gitlab)
¢ Container Engine for Kubernetes (OKE)
¢ Identity and Access Management (IAM)
¢ Visual Builder Studio
¢ Docker containers can be pushed/pulled by Docker CLI and API

DEMO PLATFORM: DEVOPS
¢ End-to-end, continuous integration and continuous delivery (CI/CD) platform
¢ Service provides:
¢ Private Git repositories (allows connections to external code repos)
¢ Build pipelines
¢ Deployment pipelines

DEMO PLATFORM: RESOURCE MANAGER
¢ Automate the process of provisioning Oracle Cloud Infrastructure resources
¢ Infrastructure as Code (IaC) with HashiCorp Terraform using specific OCI Terraform provider
¢ Managing OCI resources in a declarative way
¢ Ensure consistent infrastructure management by supporting
¢ Immutable infrastructure approach
¢ GitOps

DATA APIS AS THE BASIS FOR DATA
MESH

DATA PRODUCTS
¢ In direct connection with microservices from the classic SD environment
¢ Operational Applications vs. Analytical Applications

CROSS-DOMAIN DATA PRODUCT USAGE

KEY TAKEAWAYS
¢ Software development practises are making their way in the world of Analytics
¢ Data API and DDD are essential for implementing Data Mesh
¢ Data APIs help you to
¢ Decouple data stores, structures and technologies
¢ Gain insights into data usage (Observability)
¢ Control data access consistently (AuthN & AuthZ)
¢ APIs must be compliant, functional & findable (Consumable APIs)
¢ APIs != REST
