Key Operational Priorities

  • 01

    24×365 Continuous Availability

    • Always-on operation of internet and mobile banking

    • High-availability requirements for MTS and HTS

    • Non-stop service for insurance cores

    • Even a few minutes of downtime translates directly into financial and reputational risk

  • 02

    Peak Transaction Control

    • Traffic surges during IPO subscriptions

    • Increased concurrent access at moments of interest-rate or exchange-rate changes

    • The limits of designing around average traffic

    • The need for concurrency control based on active users

  • 03

    Regulation & Audit Readiness

    • Compliance with electronic-financial supervisory regulations

    • Response to ISMS and personal-data protection

    • Management of log, access, and change history

    • An operations-documentation framework that supports audits

  • 04

    Legacy + Cloud Hybrid Complexity

    • A mix of mainframe, UNIX, Linux, and cloud

    • Expansion of AI, AICC, and data-analytics technologies

    • Technologies multiply, but operational integration lags


  • 05

    Accountability-Driven Governance

    • Unclear ownership of operational responsibility

    • Decisions dependent on individual staff

    • A lack of recurrence-prevention frameworks for incidents

    • The need for an SLA-based management structure

Industry Challenges

24×365 Non-Stop Requirements

  • Internet and mobile banking, securities MTS/HTS, insurance-core systems, etc.

  • Even a few minutes of downtime translates directly into eroded trust and financial loss

  • A service outage is not merely an IT issue but a brand risk

Large-Scale Transaction Processing and
Surge Response

  • Traffic spikes during IPO subscriptions, events, and interest-rate changes

  • It is essential to maintain system stability amid surging
    concurrent users

  • A structure that controls for peak moments, not average traffic,
    is needed

Explosion of Unstructured Data and RDBMS Limitations

  • Growth of unstructured data such as news, terms, electronic subscriptions, and user-behavior logs

  • Exposure of existing RDBMSs' schema rigidity and scalability limits

  • Licensing-cost pressure from commercial DBs such as Oracle
    (a case where 3-year TCO went from KRW 2.0B to KRW 0.6B)

Regulatory, Security, and Audit Response

  • Compliance with regulations such as electronic-financial supervisory rules, ISMS, and the Personal Information Protection Act

  • Mandatory log retention, recording retention, access control, and change-history management

  • A requirement to document operational standards for audits

An Environment Mixing Legacy and New Technology

  • A mixed structure of mainframe, UNIX, Linux, and cloud

  • Expanding adoption of new technologies such as AICC, AI, and data analytics

  • Adding technology is easy, but integrating operations is difficult

Ambiguity in the Operational-Accountability Structure
