Cloud Migration of Legacy Systems Leads to Reduced Operational Cost

About the Project

Our client, an airline carrier company, has been managing hundreds of applications and services running on outdated on-premises infrastructure. They have been struggling to keep up with the demands of its IT operations and their hosting provider could no longer scale with the airline’s growing needs without driving up maintenance costs. Due to our long-term collaboration, Createq’s personnel including Sofware Engineers, Domain Experts and Solution Architects, worked together with the client to come up with the solution for their ongoing troubles.

The Challenge

The client's company was at a critical juncture as its legacy infrastructure struggled to meet the demands of a growing business. This created several pressing challenges:

• Operational Strain: Routine tasks became increasingly cumbersome, slowing productivity and stalling growth.
• Limited Scalability: The existing systems lacked the flexibility to adapt to business expansion and evolving needs.
• Inadequate Monitoring: Reactive instead of proactive, the monitoring systems made it challenging to prevent or swiftly address issues.
• Fragile Disaster Recovery: Frequent service disruptions, coupled with lengthy resolution times, undermined operational reliability.
• Technological Obsolescence: The aging, monolithic architecture couldn’t bridge the widening gap between the company's capabilities and modern technological standards.

Recognizing these challenges, CREATEQ's engineering team collaborated closely with the client to diagnose the root causes and remove operational bottlenecks. Together, we established realistic and measurable goals centered on reducing costs, enhancing automation, enabling scalability, and implementing robust disaster recovery and monitoring solutions.

The Solution

To overcome all these challenges, the client decided to migrate the complete infrastructure to cloud. The architecture board chose Microsoft Azure as a cloud platform. To reduce costs, we advised moving the infrastructure from an expensive hosting provider to internal IT departments. This also provided a long-term investment for the future.

The migration process was executed in phases. First, a thorough assessment of the company's IT environment was conducted to identify suitable applications and services for migration. A detailed migration plan was developed, outlining timelines, resource allocation, and risk mitigation strategies. Pilot projects were then executed to evaluate Azure's performance and capabilities for specific applications, refining the migration strategy and addressing potential challenges.

To migrate applications, services, and data to Azure, a combination of strategies was applied in 3 phases:

The Results

The cloud migration delivered transformative benefits for the airline carrier, including:

• Improved Team Collaboration: Enabled the efficient organization of dislocated teams, fostering better communication and productivity.
• Cost Efficiency: Achieved significant cost savings by consolidating infrastructure and leveraging Azure's flexible pricing model.
• Enhanced IT Operations: Transformed IT processes through a fully cloud-native approach, optimizing performance and reliability.
• Business Innovation: Freed up resources to focus on core business competencies, driving forward innovation and enhancing market competitiveness.

This successful migration to Azure not only streamlined operations but also positioned the airline for sustainable growth and continued success in a rapidly evolving industry.
