7/14/2000TWIST 2000 ClearNet: Centralized Control in a Decentralized Architecture for Online Financial Services Nasser Barghouti ONEWORLD Software Solutions San Diego, CA

7/14/2000TWIST 2000 ClearNet Infrastructure for online financial applications at Bear Stearns & Co. Heterogeneous platforms (NT, Sun Solaris, IBM AS400, IBM mainframe). High level of security. Replicated infrastructure for disaster recovery and load balancing.

7/14/2000TWIST 2000 ClearNet Applications Suite of 30+ applications. Portfolio management. Online order entry. Broker applications. Online statements and account management. Securities research.

7/14/2000TWIST 2000 ClearNet History Mainframe applications…direct connectivity between clients (brokerages) and Bear Stearns Clearance organization. Client-Server applications replaced mainframe apps in late eighties. Browser-based applications replaced client- server ones starting in HTML (thin) and Java (thick) clients.

7/14/2000TWIST 2000 Logical Architecture Presentation layer Java applet HTML C++ servlets Server Java ASP/ COM Business logic layer Semi-permanent data layer Permanent data layer Tables Stored procs Gateway objects Mainframe regions Market data feeds

7/14/2000TWIST 2000 Internet Private access Tier 2Tier 3Tier 4Tier 1 Physical Architecture of ClearNet

7/14/2000TWIST 2000 What is Centralized? Centralized authentication: single sign-on, unified entitlements system, re-usable software components/interfaces. Centralized market data feeds. Centralized billing. Centralized connectivity to legacy systems (books & records; trade settlement). Centralized mainframe operations organization.

7/14/2000TWIST 2000 What is Decentralized? Decentralized application development. Decentralized testing. Decentralized application execution. Decentralized data access and manipulation. Decentralized software distribution model. Decentralized business decision making. Decentralized profit centers.

7/14/2000TWIST 2000 Tensions Centralized control over data vs. decentralized access/manipulation by various applications. Diverging business needs vs. centralized infrastructure (CIO vs. Business leadership). Centralized security monitoring vs. flexible, decentralized access. Disaster recovery: centralized control for a decentralized infrastructure.

7/14/2000TWIST 2000 Examples of tension (I) Application X has a need to add a field to the centralized mainframe database but is unable to effect the change…developer decides to keep data in an alternative database (diverge). Need to synchronize alternate database with mainframe database (nightly batch job)…soon BIG MESS.

7/14/2000TWIST 2000 Examples of tension (II) Application Y needs a specific authentication structure that is not provided by centralized single sign on system. Developer of centralized single sign on system codes “additional features” and produces a specialized build for App Y. Centralized SSO system must support standard plus specialized feature. SUPPORT HEADACHE…Multiple streams.

7/14/2000TWIST 2000 Examples of tension (III) Company has a centralized Market Data infrastructure. Application Z needs market feed from Thailand market, which is not yet supported by centralized system Developer contracts with another market data feed to get needed data. Company pays for and supports competing infrastructures...

7/14/2000TWIST 2000 Examples of tension (IV) Disaster recovery setup in geographically distributed locations. Persistence of online customer information. Data replication and manipulation. Transaction management (online order entry; online trade entry).

7/14/2000TWIST 2000 Conclusions Cannot resolve many of the tensions without restructuring organization. Transition from centralized to decentralized may not be worth it…replace the whole thing (spin off?) Transition cannot be done with the software development organization that produced the centralized solution.

7/14/2000TWIST 2000 ONEWORLD Software Solutions Global company: software lifecycle support (definition to deployment) Partner with software product companies (e.g., IBM, HP, Cisco, Endeavors Technology) to help them meet time-to-market and increase capacity. 300 people in 5 centers (SV, SoCal, Boston, Beijing, Amman)
