Solution
 
Nagarro provided Siemens with a comprehensive solution that covered the following aspects.

1. Cloud Optimization

Nagarro implemented best practices and tools to optimize the client's cloud infrastructure, such as AWS Well-Architected Framework, AWS Cost Explorer, AWS Trusted Advisor, and AWS CloudFormation. We also helped them adopt a serverless-first approach and migrate their legacy EC2 instances to AWS Lambda functions, which reduced the operational overhead and improved the scalability and efficiency of their cloud applications.
