Challenge
Before modernizing their applications, Delta Holding faced a number of operational challenges that hindered efficiency and reliability. Workflows relied heavily on a single person managing multiple roles, which increased the risk of errors and inconsistencies. The lack of adoption of modern DevOps technologies and standardized deployment processes aggravated these issues. Testing was performed directly in production environments, without dedicated test setups or standardized methodologies, and there were no automated or mandatory unit tests, resulting in frequent reactive fixes to live systems. The lack of streamlined processes led to significant unplanned work and constant interruptions due to project-specific changes. In addition, the company had to manually manage numerous different systems and software versions, leading to further inefficiencies and increased operational risk.
Solution
Delta Holding recognized the need for specialized expertise and decided to outsource the modernization of the apps to XLAB. After successful proof of concept on the Azure platform, the company was impressed by XLAB’s professionalism, commitment and effective implementation. XLAB then guided Delta Holding through a structured implementation process to introduce modern DevOps practices, introducing standardized deployment pipelines, automated testing strategies and dedicated testing environments to minimize production disruption. Continuous integration and deployment workflows were also implemented to increase efficiency and reliability. This involved working closely with Delta Holding’s internal team to ensure knowledge transfer and the development of long-term internal capabilities.
Results
Faster Delivery and Reduced Costs
Deployment times were reduced by 20–30%, enabling faster delivery and updates. At the same time, infrastructure and maintenance costs dropped by an estimated 20–25%, improving overall efficiency.

System stability and responsiveness saw significant improvements, directly supporting business goals and enhancing the overall user experience.
Scalability for Future Growth
