Enhancing Configuration Management at Verizon using AWS Systems Manager

https://aws.amazon.com/blogs/mt/enhancing-configuration-management-at-verizon-using-aws-systems-manager/
We needed a solution to implement application deployment as part of the design using ServiceNow and AWS Service Catalog. I worked on the solution to introduce AWS Systems Manager (AWS SSM) and Ansible to help application teams configure their applications.

Architecting AWS Service Catalog

AWS cloud provisioning platform for non-technical persons to provision AWS services. This solution was widely adopted in the company and helped the cloud migration process for application teams. It required working with AWS BA and SAs to use Service Catalog and ServiceNow connector to create the cloud formation templates as products.
