Project overview
The client tasked Software Mind with taking over the technical support service of existing legacy solutions and, as a next step, migrating some components to Google Cloud. The process of transferring the responsibility over technical support had to be transparent for the end customer, and the support level had to remain at the defined SLA level requested by the client.
Client background
A subsidiary of one of the world's largest telecommunications corporations, our client is one of Poland's largest fixed-line and mobile service providers.
Main challenges
Software Mind’s team had to provide support for already built applications based on Oracle's ETL, employing PL/SQL packages, procedures and functions. The technology stack, now considered outdated and not up to modern software development standards, was proving to be a limitation for the user in many operational aspects. The support transition process, a time-sensitive operation, was set to be completed within a strict one-month deadline.
Implementation
Software Mind analyzed the existing documentation, gained remote access to the legacy platform and performed several workshops with the client’s operational team to gain insights into the platform, maintenance tasks and challenges that the client dealt with. After collecting the necessary information, we conducted the source code and legacy platform audit. It resulted in a report that listed existing issues and platform bottlenecks, along with suggestions on how to address these problems. Due to our team’s involvement, the platform was covered by a 24/7/365 technical support service after one month.
Additional changes
At the same time, Software Mind was involved in developing a new platform. The new solution was built in a public cloud environment – Google Cloud Platform (GCP) – with a modern and flexible approach to software development. It’s expected that the legacy solution will be migrated without impacting any business processes. Until the migration process to the public cloud is completed, the legacy platform must be fully operational under a stringent SLA. After the migration, the new platform will be supported according to the same SLA requirements.
