  • IT OBJECTIVE

    To implement a Citrix App Layering unified application delivery service.

  • Migration of bank applications to separate layers
  • Arrangement of application administration without allowing applications to affect each other or the work of users
Solve a similar problem

IMPLEMENTATION

Jet Infosystems experts developed a methodology for transferring applications to various layers and a migration process.


First, an application delivery system was deployed. Each application was separately transferred to a separate layer and tested on a focus group of 50 users; only subsequently was it then implemented. All updates were carried out live, and we ensured that any prompt actions had zero impact on the bank's business.


Over the course of 9 months, 200 key bank applications were migrated to the new platform. Total load is distributed between two data centers, each able to accept 100% user traffic volume in the event of a failure of one of the sites. The POD concept (logically isolated containers) was used to protect against logical error. This allows the bank to carry out scheduled work, such as application updates, without service interruptions.

We have significantly increased application availability. Now the bank can promptly use new application versions, updates are easier, and the connection of new users has been simplified.
