If Integration wasn’t complex already

Cloud introduces a new dimension of complexity…

Cloud Integration: Problem Overview

• Different styles of integration in SaaS apps • High-Security (risk) systems running on-premise• Varied integration protocols - file, events, WS, APIs, jobs

• Tribal mapping knowledge• Inconsistent exception handling • Functionality gaps across the end-to-end stack

e.g. message ordering/sequencing

• White-box handling of routing (using Naming Service or endpoint URLs) between various Oracle cloud services, for both sync (HTTP) or async (JMS) messages

5

Oracle Integration Cloud Overview

• Integrates applications across clouds and on-premises– Platform for pre-built flows, customizations and new custom

integrations – Supports event-driven messages (through Messaging Cloud)

and file-based payloads – Rich Connectivity with Cloud & On-premise Connectors – Automatically provisioned and associated with SaaS Apps

• Simplified design time and runtime console – Simplified: Web based, Point & Click integration experience– Highly Visible: Rich monitoring & error management– Lifecycle : Support both on-premise, cloud lifecycle tools– Rapid Mapping using Recommendations– REST APIs & Embeddable UIs

Salesforce

OracleSOA Cloud Service


OracleSOA Suite

• SOA Suite in the Cloud– Platform for Orchestration, application integration, API

management, virtualization, orchestration, streaming analytics, B2B, MFT, connectivity, business monitoring dashboards

– Fully portable, lift and shift from/to on-premise– Identical components to Oracle SOA Suite for faster

deployment portability

• Complete access to product surface area – Access to Weblogic console, Enterprise Manager & Filesystem– Rapid and fully automated provisioning– Secure, Highly Available with Clustering– Fully Managed i.e. easy patching– Build anywhere, deploy anywhere

Cloud to On-Premise Integration Patterns

Integration Patterns• Messaging (Async) - Hybrid Cloud

• Use On-Premise SOA to poll Messaging Service• On-Premise SOA hosts the adapter

• Proxy (Sync or Async) – Hybrid Cloud• Use On-Premise SOA with a web-Proxy in DMZ• ICS/SOACS sends message through Proxy• On-Premise SOA hosts adapter

• Agent (Sync or Async)• Agent is started on the customer’s internal network• Agent establishes a communications tunnel• SOACS or ICS send msgs through tunnel to the Agent• Agent hosts adapter to communicate to the App

When should you consider Integration Cloud Service

Legacy

ON-PREMISE


Salesforce



Best When– Most integrations are between cloud-based applications

– Low to no need for integration to on-premise, or between on-premise applications

– Integrations are less complex

– In-house integration skills are limited

– Focus is on rapid integration

17

When should you consider SOA Suite Cloud Service


ON-PREMISES


Salesforce



OracleSOA Suite

Best When– Want to balance quick delivery projects with a systematic

approach to integration

– Need to handle combinations of

• Cloud to On-premise

• On-premise to on-premise

• Mobile, IoT, B2B, API Management

– Want to extend an established on-premise integration platform

• Quickly attach to existing on-premise integration flows whilst leveraging the ease of use of the Cloud

• Want to move existing integration flows to the public cloud

Cloud 2 GroundMessage Exchange Patterns

• Synchronous request from cloud to on-premise to retrieve data– Getting the status of an order from EBS at real-time

• Events in cloud triggering Async message exchange with on-premise– Creation of an incident in RightNow causes creation of service request in EBS

• Events in on-premise triggering Async message exchange with the cloud– Service request update event result in Async message based synchronization with RightNow

• Synchonized data extracts from on-premise applications with SaaS applications– EBS based customer data synchronized with CRM

20

21

Cloud 2 GroundAgent Architecture Guidelines

• Not required to open inbound ports to communicate with on-premise applications

• Not required to expose any private SOAP based web services

• Not required to host on-premise assets on DMZ

• Not required to have an existing J2EE container to deploy Agent on

• Not required to have IT personnel monitor on-premise component

22

Cloud 2 GroundAgent Architecture

• Two components, Cloud Agent installed on ICS & Ground Agent installed at on-premise.

• Agent uses Messaging Cloud for message exchange.

• Agent only allows connections established to Oracle Cloud. It dis-allows explicit inbound connections.

• Uses JCA adapter framework to invoke on-premise endpoints.

Cloud 2 GroundAgent Features

• Perform silent installation of Agent through Installer

• Register Agent instances with Integration Cloud Service

• Test on-premise applications / data source connections from ICS through ping

• Fetch on-premise EIS metadata when designing ICS flow

• Transfer artifacts to on-premise location using activation redirection

• Allow execution at on-premise location using runtime redirection

24

Cloud 2 GroundAgent Features

• Supports multiple agents for load distribution & high availability

• Group agents on functional / process or organization level

• Supports multiple message exchange patterns (Cloud <-> Ground)– Synchronous Request / Reponse– Fire-and-Forget

25

Cloud 2 GroundWhat is included with the Agent?

• Agent can be downloaded (from ICS) & installed on demand• Included binaries with Agent:

– WebLogic Server– Java Required Files (JRF)– Agent & Messaging Cloud Service (OMCS) client– On-premise adapters (JCA based)

• Easy connect Agent with ICS– Supply username & password via Agent Installation UI or command line prompts

for authentication against ICS.– Need active OMSC subscriber

26

Cloud 2 GroundAgent Registration Flow

Define Agent in ICS

Download Agent from ICS

Install Agent On-Premise

Create connection in ICS for on-premise endpoint

Associate Connection with an Agent

27

Cloud 2 GroundAgent Installation Flow

• Installer performs pre-installation checks– Version check, fetches OMCS credentials and registers Agent instance

• Installs WebLogic Server• Executes RCU for OPSS (on JavaDB)• Creates WebLogic domain including JRF• Configures Agent

– Setup home and classpath with shared libraries• Starts the Agent

28

Cloud 2 GroundAgent OMCS authentication

• Additional AppID created during ICS instance creation– Used by all agents for authentication

• Agent installer will retrieve AppID and OMCS password from ICS– Agent fetches credentials to on-premise via REST interface over SSL– AppID and password is stored in the on-premise WebLogic CSF store (OPSS)

• Agent uses HTTP Basic Auth over SSL to authenticate with OMCS and ICS
