AWS Transform for mainframe refactor

Cost disclaimer

SDE costs disclaimer (as-of Dec., 2024)

The deployment and use of AWS Blu Age SDE involve the creation and consumption of resources across multiple AWS services. The estimates provided below represents a Rough Order of Magnitude (ROM) estimate of potential AWS inducted costs. And, actual expenses could vary based on specific project volumetric needs and requirements, geographical location, and the organization's existing infrastructure and expertise.

Cost baseline

The table below details the principle and initial cost based on a baseline of services and resources provisioned by AWS Blu Age SDE for AWS Blu Age CI and RTS:

In addition, for the duration of the project, each developer needs to use his own development environment. This environment is composed of at least 2 EC2 instances:

FeatureConfiguration (default)Hrs / weekDescriptionMonthly Cost (USD)

EC2 IDE for Developer1 t3.2xlarge12/5Windows EC2 integrating development tools120
EC2 for Database restore1 t3.small12/5EC2 used to restore databases6

AWS Blu Age SDE is scalable according to the needs of each project and depending on its organization as a team (head count and labor workload) i.e., depending on the size of the project, the number of developers onboarded, the number of test cases, the volume of data to be processed, the volume of network traffic and the progress in the project, additional costs will apply. We recommend configuring and using EC2 stop/start functionality available through AWS Blu Age DevOps Setup to optimize infrastructure costs based on your actual usage.
