Migration of Legacy Software to the Cloud

Migrating a large landscape of legacy applications to the cloud without exhausting DevOps resources.

Initial Situation

Eurotours International, a leading provider in multi-channel travel distribution, faced the challenge of migrating legacy applications to the cloud. The existing on-premise systems were no longer aligned with updated business requirements.

15 Developers on the project

40 years of in-house development

This lead to a number of challenges

The monolithic architecture lead to different challnges, including:

Knowledge Silos

The implemented proprietary software solutions needed lots of expertise from specialized expert which turned onboarding into a bottleneck.

Extensive Administration Effort

Running systems on-prem means administering and maintaining them as, well as paying expensive fees.

Slow processes

The flexibility of on-prem slowed down processes, making it hard to keep up with the speed of business needed to thrive in todays environment

Expensive Licences

The existing systems were highly dependent on a number of licences, which were costly to maintain.

Main Goals

Some of Eurotours goals for the migration include:

Simplify DevOps

Lower cost of ownership while giving more control over the infrastructure in the hands of developers.

Break up monolithic architecture

Improve testing capabilities, make know-how more accessible and speed up the onboarding of new developers

Getting rid of on-premise

Keep the flexibility of on-prem while not having to worry about running and maintaining the architecture.

Solution and Implementation

With Codesphere

Self-Service to eliminate risks

Traditionally, skill centralization and dependencies are associated with risks. Codesphere allows for immediate, real-time onboarding, enabling any team member to effortlessly manage tasks from scaling applications to setting up domains.

This simplifies operations but also fosters independence and flexibility across development teams.
