Azure-Powered Cloud Migration of a Leading Navigation Services Provider

Client

TomTom is a leading Dutch multinational navigation services provider.

Challenges

• Frequent outages caused by faulty data center infrastructure and breached vendor SLAs. 
• Performance affected by limited resources and use of legacy applications. 
• Scalability issues due to a limited number of servers in the cluster. • Dependence on the platform engineering team for infrastructure support due to access restrictions of on-prem data centers. 
• Lack of disaster recovery configuration due to stretched resource bandwidth. 
• Limited test and Continuous Integration (CI)/Continuous Development (CD) automation and unavailability of one-touch infrastructure creation. 

LTM Solution

• We used the pipeline-driven migration approach to modernize the client’s infrastructure using Azure Services and drive operational efficiency and agility. 
• Reduced memory consumption due to Virtual Machine Scale Sets (VMSS) autohealing using a Virtual Machine Stock Keeping Unit (VM SKU) with a higher CPU core, enabling accelerated networking. 
• Implemented a permanent outbound load balancer on the source application so that the outbound calls have a static IP and can be whitelisted on the destination application. 
• Upgraded to newer versions of application servers and Java Development Kit (JDK) versions to enable Azure migration. 
• Unplugged all ActiveMQ dependencies from the applications and introduced Azure Service Bus for asynchronous communication. 
• Implemented auto-healing of application to minimize performance and availability degradation. 
• Recreated performance scripts of legacy applications and implemented database secret Key Vaults (KVs) to validate test cases. 
• Created Continuous Test (CT) pipelines for all applications and scheduled them for nightly runs. 

Business Benefits

• Ensured business continuity through an incremental migration approach.
• Increased migration speed by templatizing the pipeline development.
• Decoupled infrastructure and application code to simplify management.
• Minimized hindrances in the application development using the CI-CD-CT approach.
