Migrating legacy app infrastructure to AWS Cloud

Our client, a leading US-based insurance and investment services company, has provided innumerable people with the ever-increasing essentiality of life insurance cover, while enhancing the wealth of families and retired people, adopting various market strategies to create wealth and help increase its customers’ financial security.

The client needed to move its legacy application infrastructure from an on-premises location to an AWS Cloud environment. This included the automation of CI/CD pipelines, integrations, and application hosting in the cloud environment.
 
Due to manual release processes, the client’s application had undefined deployment/releases leading to longer deployment cycles and challenges in scaling up in their on-premises environment, contrary to their business needs.
 
The client’s main objectives were to:

• Improve business service delivery by reducing dependency on manual deployments
• Boost profitability by utilizing in-built AWS infrastructure to provide on-demand hardware, thus reducing own IT hardware costs
• Acquire the ability to monitor traffic patterns in near-real time, which would also help future research and data analysis

Tieto Tech Consulting reviewed the current application and integration landscape and analyzed customers’ business requirements. Based on the business need and requirements captured, we adopted a cloud migration approach comprising the following features:

• Establishment of a CI/CD pipeline for better service delivery and business benefit
• Cost-optimized AWS infrastructure for hosting the legacy application
• Development of automated infrastructure, deployments, and auto-scaling using AWS, Terraform, and PowerShell scripts
• Migration of on-premises servers to the cloud by following a lift-and-shift approach using modern technologies

Key success factors of the project:

• Automated and secure
  Due to the automated infrastructure and deployment automation, the use of business features by application users increased. The manual time duration was reduced by 90%.
• Cost-effectiveness with cloud
  IT hardware cost dropped with the AWS Cloud, providing on demand infrastructure. Near real-time traffic monitoring was accessible, and proactive application health analysis was provided.
• Seamless integration
  Using the latest DevOps migration framework allows the client to faster integrate any new system in the future to be better prepared for any volatility in the market.
