Internet of Things: Thinking services

Internet of Things brings tremendous promise to integrate every smart “thing” in this world. Having been an integration practitioner for more than decade, I find it hard to resist drawing a parallel between these 2 worlds: the world of integration & the world of Internet of Things.

- IoT market is Wild Wild West - fragmented, full of competing standards & proprietary solutions - exactly where integration was in 90s before SOA, webServices & XML redefined the landscape. ETSI is doing significant work to unify different standardization efforts and Oracle is actively contributing to this effort. But, there is lot of ground to be covered.

- Smart things i.e. sensing devices, medium powered gateways represent the IoT endpoints. This is akin to B2B integration scenario where cloud apps, B2B apps etc are communicating with the integration platform. Of course, we are now talking about hundreds to even millions of devices sending data to an enterprise versus a handful of apps in a traditional integration project

- There are wide range of devices supporting different interfaces, communication protocols and lack interoperability. It’s virtually impossible for any vendor to provide connectivity solution to entire breed of current and emerging devices. Before enterprise applications started becoming service enabled, we all grappled with the challenge of dealing with myriad of applications exposing their functionality through proprietary interfaces.

List could go on and on. But, it makes one think whether a service oriented approach could be considered when building an IoT application. Before we apply service oriented principles to IoT architecture, we should acknowledge the fact that IoT does bring its unique set of challenges

-   Security: How do I ensure that data in motion (traveling between devices, gateways, network to enterprise apps/cloud) or data at rest is secured?

  - Identity – Device is the new data source. But, there is no human associated with a M2M device unlike an enterprise app or a mobile. This makes it challenging for enterprises to manage the device lifecycle - onboard/off board new devices and manage their identity

  - Device Management: How do I remotely manage and monitor a device throughout its lifecycle (diagnostics, troubleshooting, configuration)?

  - Analytics: IoT will lead to data deluge. Enterprises would need to think beyond traditional business intelligence tools. How do I analyze IoT data at real-time (i.e. is there a medical emergency based on data received from blood pressure monitor?) to how data is analyzed for historical & predictive analytics (How do I improve patient care based on medical trends from patients over past 6 months)?

      In a typical SOA Composite application, we have collection of business processes, business services, data services with each layer building on top of the other to enable loosely coupled integration. Data services expose application interfaces as services which could in turn be orchestrated together to create a business service. E.g. “Create Employee Record” Data Service is responsible for creating a new record in Fusion HCM application, while “Onboard Employee” business service would orchestrate several steps (read data services) needed to on-board a new employee (create employee record, provision new email account etc).


">Figure 1: Layered SOA Architecture

IoT architecture could essentially be modeled in a similar layered format. Device layer, at the bottom, is the main source of data. It includes sensing/edge devices which sense the surrounding environment and transmit data in regular intervals. These sensors, in turn, may interact with an intelligent gateway. Gateway provides data aggregator and in few cases device level data processing capabilities. Data is funneled through a communication service provider network. CSP could either play the role of the network provider or it could move up the value chain to offer IoT infrastructure services. This layer would enable seamless connectivity with different M2M devices (akin to data services in SOA) and offer the ability to remotely monitor and manage them for device connectivity.

IOT services layer is completed agnostic of underlying devices, communication protocols and connectivity semantics. This layer would include core set of services to build IoT applications (i.e. composite applications)
- Analyze data at real-time (event processing)
- Act on M2M data & events (integration service)
- Enable historical, real-time and predictive analytics (Analytics Services)
- Visualize operational and analytical data through mobile/desktop (UI Services)

- Manage data security & identity of devices/apps (Security & Identity Management Service)

Why Fusion Middleware matters to Oracle Applications and Fusion Applications customers?

Did you miss this general session on Monday morning presented by Amit Zavery, VP of Oracle Fusion Middleware Product Management? There will be a recording made available shortly and in the meanwhile, here is a recap. Amit presented 5 strategies customers can leverage today to extend their applications.


Figure 1: 5 Oracle Fusion Middleware strategies to extend Oracle Applications & Oracle Fusion Apps

1. Engage Everyone – Provide intuitive and social experience for application users using Oracle WebCenter

2. Extend Enterprise – Extend Oracle Applications to mobile devices using Oracle ADF Mobile

3. Orchestrate Processes – Automate key organization processes across on-premise & cloud applications using Oracle BPM Suite & Oracle SOA Suite

4. Secure the core – Provide single sign-on and self-service provisioning across multiple apps using Oracle Identity Management

5. Optimize Performance – Leverage Exalogic stack to consolidate multiple instance and improve performance of Oracle Applications

Session included 3 demonstrations to illustrate these strategies.

1. First demo highlighted significance of mobile applications for unlocking existing investment in Applications such as EBS. Using a native iPhone application interacting with e-Business Suite, demo showed how expense approval can be mobile enabled with enhanced visibility using BI dashboards.

2. Second demo showed how you can extend a banking process in Siebel and Oracle Policy Automation with Oracle BPM Suite.Process starts in Siebel with a customer requesting a loan, and then jumps to OPA for loan recommendations and decision making and loan processing with approvals in handled in BPM Suite. Once approvals are completed Siebel is updated to complete the process.

3. Final demo showcased FMW components inside Fusion Applications, specifically WebCenter.

Boeing, Underwriter Laboratories and Electronic Arts joined this quest and discussed 3 different approaches of leveraging Fusion Middleware stack to maximize their investment in Oracle Applications and/or Fusion Applications technology. Let’s briefly review what these customers shared during the session:

1. Extend Fusion Applications

We know that Oracle Fusion Middleware is the underlying technology infrastructure for Oracle Fusion Applications. Architecturally, Oracle Fusion Apps leverages several components of Oracle Fusion Middleware from Oracle WebCenter for rich collaborative interface, Oracle SOA Suite & Oracle BPM Suite for orchestrating key underlying processes to Oracle BIEE for dash boarding and analytics. Boeing talked about how they are using Oracle BPM Suite 11g, a key component of Oracle Fusion Middleware with Oracle Fusion Apps to transform their supply chain.

Tim Murnin, Director of Supply Chain talked about Boeing’s 5 year supply chain transformation journey. Boeing’s Integrated and Information Management division began with automation of critical RFQ process using Oracle BPM Suite. This 1st phase resulted in 38% reduction in labor costs for RFP. As a next step in this effort, Boeing is now creating a platform to enable electronic Order Management. Fusion Apps are playing a significant role in this phase. Boeing has gone live with Oracle Fusion Product Hub and efforts are underway with Oracle Fusion Distributed Order Orchestration (DOO). So, where does Oracle BPM Suite 11g fit in this equation? Let me explain. Business processes within Fusion Apps are designed using 2 standards: Business Process Execution Language (BPEL) and Business Process Modeling Notation (BPMN). These processes can be easily configured using declarative set of tools. Boeing leverages Oracle BPM Suite 11g (which supports BPMN 2.0) and Oracle SOA Suite (which supports BPEL) to “extend” these applications. Traditionally, customizations are done within an app using native technologies. But, instead of making process changes within Fusion Apps, Boeing has taken an approach of building “extensions” layer on top of the application.

2. Maximize Oracle Applications investment

Fusion Middleware appeals not only to Fusion Apps customers, but is also leveraged by Oracle E-Business Suite, PeopleSoft, Siebel and JD Edwards customers
significantly. Using Oracle BPM Suite and Oracle SOA Suite is the recommended extension strategy for Oracle Fusion Apps and Oracle Applications Unlimited
customers. Electronic Arts, E-Business Suite customer, spoke about their strategy to transform their order-to-cash process using Oracle SOA Suite,
Oracle Foundation Packs and Oracle BAM. 

Udesh Naicker, Sr Director of IT at Elecronic Arts (EA), discussed how growth of social and digital gaming had started to put tremendous pressure on EA’s existing IT infrastructure. He discussed the challenge with millions of micro-transactions coming from several sources – Microsoft Xbox, Paypal, several service providers. EA found Order-2-Cash processes stretched to their limits. They lacked visibility into these transactions across the entire value chain.

EA began by consolidating their E-Business Suite R11 instances into single E-Business Suite R12. EA needed to cater to a variety of service requirements, connectivity methods, file formats, and information latency. Their integration strategy was tactical, i.e., using file uploads, TIBCO, SQL scripts. After consolidating E-Business suite, EA standardized their integration approach with Oracle SOA Suite and Oracle AIA Foundation Pack. Oracle SOA Suite is the platform used to extend E-Business Suite R12 and standardize 60+ interfaces across several heterogeneous systems including PeopleSoft, Demantra, SF.com, Workday, and Managed EDI services spanning on-premise, hosted and cloud applications.

EA believes that Oracle SOA Suite 11g based extension strategy has helped significantly in the followings ways:

- It helped them keep customizations out of E-Business Suite, thereby keeping EBS R12 vanilla and upgrade safe

- Developers are now proficient in technology which is also leveraged by Fusion Apps. This has helped them prepare for adoption of Fusion Apps in the future

3. Consolidate apps and improve scalability

Exalogic is an optimal platform for customers to consolidate their application deployments and enhance performance. Underwriter Laboratories talked about their strategy to run their mission critical applications including e-Business Suite on Exalogic.

Christian Anschuetz, CIO of Underwriter Laboratories (UL) shared how UL is on a growth path - $1B to $2.5B in 5 years- and planning a significant business transformation from a not-for-profit to a for-profit business. To support this growth, UL is planning to simplify its IT environment and the deployment complexity associated with ERP applications and technology it runs on.

Their current applications were deployed on variety of hardware platforms and lacked comprehensive disaster recovery architecture. UL embarked on a mission to deploy E-Business Suite on Exalogic. UL’s solution is unique because it is one of the first to deploy a large number of Oracle applications and related Fusion Middleware technologies (SOA, BI, Analytical Applications AIA Foundation Pack and AIA EBS to Siebel UCM prebuilt integration) on the combined Exalogic and Exadata environment. UL is planning to move to a virtualized architecture toward the end of 2012 to securely host external facing applications like iStore

Key takeaways are:

- Fusion Middleware platform is certified with major Oracle Applications Unlimited offerings. Fusion Middleware is the underlying technological infrastructure for Fusion Apps

- Customers choose Oracle Fusion Middleware to extend their applications (Apps Unlimited or Fusion Apps) to keep applications upgrade safe and prepare for Fusion Apps

- Exalogic is an optimum platform to consolidate applications deployments and enhance performance
