Case study of the modernization project of Early Warning Network, Australia.
This project was delivered as part of a project contract assignment with Early Warning Network, Australia. We have been contracted to deliver a lift-and-shift cloud migration of the company's Geographic Notification Information System (GNIS) from a monolithic architecture to Microsoft Azure and then conduct and implement a cloud integration project, through which we have established an understanding of sub-components of the system, compared and aligned the Microsoft Azure system offerings with current state of the architectures, created improvement plans and work packages and delivered the agreed outcome within a given time-frame and budget.
As part of the Phase 1 - lift-and-shift - migration we have encountered several difficulties with Azure cloud migration tools due to several non-conventional features implemented in the system - for instance custom-made columns in SQL server database. Owing to these reasons the lift-and-shift migration was mainly implemented with manual/semi-automated means rather using the Azure automated migration tool-sets. After implementing several test migration routines the actual production-based work has been successfully delivered on the first official attempt.
The Phase 2 work package consisted several sub-packages and detailed investigations. Since the related CI/CD delivery routine of the system was not operating anymore we established the work with a detailed review of source control and build systems, compared the business requirements and resources with Azure DevOps offerings and designed and implemented a simple yet effective CI/CD system that can be easily operated by a very small team of developers.
After successfully establishing the core development procedures of the newly migrated system, setting up source control and cloud desktops for development work we identified 3 major group of components of the established system that can be migrated/integrated into the Azure cloud offering services. These improvements are as follows:
As a result of this successful migration exercise the organization was able to hire a full-time developer who can only focus on reviewing and correcting the existing code-base and being able to deploy the newly delivered fixes and features to staging and production environment several times a day - or as its required.
