Migrating the Application Integration Solution for a Leading Icelandic Bank with Zero-Downtime

About the Customer

The customer is an Icelandic bank that traces it roots back to 1930. The bank operates in the Greater Reykjavík area as well as in the largest urban areas around the country. In 2016 the bank had the third largest market share of the current accounts in Iceland (30%). The Bank has 21 branches all over the country and over 100,000 customers.



The Bank handles all its integration using Microsoft BizTalk Server. There are quite a few BizTalk Applications with hundreds of endpoints. BizTalk Interfaces connect to 50+ external systems using wcf service, MQ, MSMQ, SAP, FILE, IDOC, SQL, FTP, SFTP and Oracle endpoints. The BizTalk layer connects to 3rd Party applications like Swift, Agresso, Calypso, Sopra and credit info Systems etc. Besides, it can handle complex integration in areas like Credit and Debit Payments, Loans, Notifications like SMS, Email etc.

The Bank was looking to migrate the Application Integration Solution on Microsoft BizTalk Server 2006R2 to BizTalk 2016 and Azure Cloud.

Tarento as the partner of choice

Tarento partnered with the customer to implement the migration to BizTalk 2016 and Azure Cloud.

Tarento’s successes with large scale Cloudification projects, its capabilities on the Microsoft stack and enterprise cloud, positioned it as the ideal partner.



The Bank faced several roadblocks to moving to a highly reliable BizTalk 2016 Environment:

  • The need to have zero down time and improve performance while migrating
  • Migration of EAI and B2B Solutions from Microsoft BizTalk 2006R2 to Biztalk 2016 / Azure
  • New EAI and B2B application integration Solution needed to be designed and developed for complex business scenarios
  • The system had to be made GDPR compliant
  • Timeline was a constraint as BizTalk 2006R2 as a product was coming towards its End-of-Support phase
