Online Application System – Education Broadcasting System

Altibase’s hybrid architecture allows EBS to effortlessly handle the increased capacity while also providing stability during peak transaction times.

Education Broadcasting System (EBS) is the sole public television and radio network in South Korea. With national reach, EBS promotes continuing, supplemental education for all South Koreans. EBS, through its online channel, EBSi, offers further educational ubiquity through its e-learning and online application systems.


  • EBS focused on implementing a CRM platform that integrated Single-Sign-On (SSO) login features with uninterrupted connectivity and deeper educational solutions. With its lofty goals, EBS quickly realized that the existing multiple data-heavy systems could not meet its needs. EBS could not deploy the first step of its CRM as its systems could not cope with the demands of 10 million core subscribers utilizing the SSO property.
  • EBS’s initiatives required continuous up-time for 100,000 simultaneous and active user sessions.
  • A critical, feature-rich application was “EBS Apply”, an online admissions process designed to help high school seniors with college admissions. With the recent memory of a similar substandard launch in the private sector, fail-safe preparation was top-of-mind.
  • The new portal’s prerequisite was the elimination of social security numbers for logon. Although this satisfied EBS’s “clean site” requirements, it placed a heavy burden on the system.


EBS has adopted Altibase since 2014. Altibase’s hybrid architecture with HA and replication features has allowed EBS to effortlessly handle the increased capacity while also providing stability during peak transaction times. Specifically, even with widespread system demands during high-use periods (college application season), its system proceeds glitch-free.


  • EBS now has a robust CRM platform that provides a wealth of e-learning, personalized web services and continuing education for all of South Korea.
  • EBS, without issue, handles its primary 10 million subscribers with SSO features.
  • EBS processes 100,000 parallel sessions with ease, doubling its capacity.
  • Leveraging Altibase’s hybrid architecture, all account information, past and present, resides harmoniously for optimal use either in-memory or on-disk.
  • Readily available personal, proprietary and data-driven information permits EBS to process vast college applications through its ‘EBS Apply’ service. This gives students invaluable utility, assisting them with the growing demands of college admissions.

EBS ReplicationTechnical Details – Online Application System


EBS had a new project initiative to build a CRM system infrastructure for subscribers of both the primary EBS and EBSi websites. EBS is the broadcaster’s flagship site with 8 million subscribers, and EBSi is the website geared toward high school students with 2 million subscribers.

One of the technical challenges of this project was to implement an integrated SSO identification management system for both websites that could support and enhance the performance for the high number of concurrent users. The company also wanted to abandon the use of associating a social security number with each account. The primary technical concerns were the system stability, the performance and the flexibility to maintain historical data.

Altibase has enabled EBS to architect an ultimate system that could satisfy all technical goals of the project in terms of performance, HA, scalability and storage flexibility.

In this architecture, using the out-of-the-box replication feature to maintain the integrated account data, EBS deploys Altibase on two separate nodes with a dynamic HA and scalability concept, making use of both active-active and active-standby configurations. During normal operation periods, the system would use the active-standby configuration which provided EBS with the capacity and stability to handle typical workloads (an average of 50,000 concurrent sessions).

The active-active configuration was the choice to handle high transaction volumes for the peak period when a large number of students submitted their undergraduate applications. The active-active configuration provided EBS with the scalability to handle 100,000 concurrent sessions across two participating active Altibase nodes.

Altibase’s hybrid architecture allows EBS to handle an increasing number of historical data for login and logout times and web pages visited with no constraints on the storage capacity.

EBS’s identification management system also benefits from the fact that Altibase is a full-featured DBMS and standards compliant. Altibase’s standard interfaces such SQL92 and JDBC make the lives of EBS’s application developers easy. Altibase’s full ACID and SQL compliance has allowed the developers to easily learn and administrate Altibase and has eliminated the need for costly retraining and additional hiring required of different database paradigms such as NoSQL.
