DSB Enterprise

The DSB offers Enterprise as an additional service for OTC ISIN and UPI users with programmatic access. This service is optional and not required for general access and connectivity to the DSB.

An Enterprise User with OTC ISIN and UPI subscriptions must be an Enterprise User for both services.

  • Designed specifically for end users with a requirement for higher throughput rates & lower and/or consistent latency
  • No change to connectivity APIs
  • The private stack is scalable & configurable calibrated for the user’s performance expectations

Enterprise Service Model

Who should consider the DSB Enterprise service?
  • The Enterprise Service is aimed at programmatic users of the ISIN or UPI Service that require higher resiliency or higher capacity or lower latency than is offered by the standard shared service 
  • The Enterprise Service utilises private and dedicated infrastructure for each user to:
  • Improve and stabilise the latency of all DSB API calls
  • Improve the resiliency of the DSB Service by utilising dedicated infrastructure
  • Increase the number of ISIN and/or UPI record creations and the frequency at which ISINs and/or UPIs are created
  • Increase the number of ISIN and/or UPI record searches and the frequency at which they are searched
  • Increase the number of times that file-download/reconciliation can be accessed

The Enterprise Stack

How does the DSB Enterprise service work?
  • The DSB is deployed in the cloud (Amazon AWS)
  • The DSB maintains dedicated infrastructure for each Enterprise User
  • The additional infrastructure is referred to as the “Enterprise Stack”
  • Each Enterprise Stack is dedicated to one Enterprise user, it is not shared with anyone else
  • The Enterprise Stack is resilient:
    – No single point of failure
    – Available in both the DSB’s Primary and Disaster Recovery environments
  • The Enterprise Stack allows users to increase their operational capacities whilst maintaining consistent low latencies (without affecting the shared
  • The same Enterprise Stack must be used to access both the OTC ISIN and UPI Services
