ESC Road to SOAHow did ESC get started?

– Prior experience developing Web Services• E-travel• USBank Interface

– SOA hype – Needed to understand how this applies to us

• We need more than the sales hype!• Researched application of technology and the “problem” it

is attempting to solve.• Developed a white paper that described the application to

our environment and our challenges.

– OMB Architecture direction described for e-government and LOB initiatives

• Described in “Services and Component Based Architecture (SBCA), A Strategic Guide for Implementing Distributed and Reusable Components in Federal Government”

ESC road to SOA• Need to support multiple solutions for

multiple customers – Support 2 different payroll interfaces (NFC,

NBC)– Support multiple acquisition interfaces for

different customers

• Need to support integration to external e-government solutions– E-travel – USBank– E-payroll

• Need to leverage prior integration efforts

Our road to SOA

Buy-in from managementPurchased Oracle SOA Suite

(version?)Benefits Sought (PRISM Integration)• Early Success• Build out SOA Infrastructure• Promote Reuse• Enterprise Architecture

SOA Maturity Model

ESC road to SOA Maturity Level 1 (Opportunistic)

– PRISM Integration w/ GAO (Quick Win)• Services developed in phases• Dedicated resources

– Get experience building, deploying and consuming services

Maturity Level 2 (Systematic)– Apply SOA to Simple Integration

Projects• GAO PRISM – go understanding of

integration points

– Initial SOA Planning

ESC road to SOA

Identified Best Project Candidates would have following characteristics:– Event driven project/initiative

• Did not want to apply to batch driven processes since ROI would be minimized

– Initiative that included:• Lookups • Transactional processing

– Initiative that an iterative approach could be applied

• So lessons learned from prior iterations could be applied rapidly

– Initiative that involved the Delphi financial system

ESC First SOA Project

• Oracle Federal Financial (Delphi) integration with Compusearch PRISM– Currently tightly integrated using OCI

• Redeveloping OCI calls into Web Services• Focus is on reuse with Delphi/PRISM as the

first consumer of services• First implementation is for GAO

SOA Project Selection Criteria

• OCI intrusive to Delphi environment– Bypasses Oracle business rule enforcements– Data issues– Many hours expended by Delphi staff to

support

• OCI supported by expensive consultants• PRISM system availability impacted by

Financial system down time• Not reusable by other acquisition solutions

or other environments

Initial SOA Objectives

• Install SOA Infrastructure– Configure Middle Tier

• Develop experience implementing and using tools

• Ensure reusability • Develop standards• Loose Integration

– Less dependency on system availability– Tight data integration

Project Timeline

Project Challenges

Resources – Resources not provided for a “build it and they

will come” type initiative– Financial centric project team too focused on

financials and not focused enough on enterprise

Lessons Learned– ESC needed an initiative to allocate resources

to embark on a SOA initiative (Delphi/PRISM Integration)

– Project team includes expertise from other ESC enterprise systems

Project ChallengesTechnical

– Product Learning Curve– Interoperability (XML standards)– Product Maturity

• Suite incompatibilities• Software bugs

– Existing Oracle packages for interfaces are not very reusable

Lessons Learned– Having expertise in other development environments

(ie. Microsoft Developer)– Spend time upfront developing design, approach, and

standards– Keep services simple and “pure” to maximize reusability

SO-A What’s Next?

• Complete Delphi / PRISM integration effort for GAO

• Implement other DOT agencies on integrated solution

• Replace FAA OCI interface• Re-engineer original e-travel and

USBank web services• Leverage services on new integration
