The School Software Company is a team of education leaders and software professionals who designed the education software tool Sleuth.

Sleuth tracks student behaviour, personal development and social development. It is used by thousands of teachers in both mainstream and specialist schools.


The hosting platform for the Sleuth software was no longer competitive, especially with the company and number of users growing. The existing solution on Rackspace also lacked the governance and security features of modern best practice.

The School Software Company needed a team who could manage the migration of their vital education software to a new hosting platform.


  • AWS CloudFormation Delivery Partner
  • Knowledge of AWS architectures
  • Experience of automating infrastructure
  • Experience of software deployment
  • Ability to understand legacy architecture
  • Ability to plan and manage the full migration

“Migrating to AWS has given us a flexible, scalable, highly secure and fault tolerant platform that costs a fraction of our previous hosting provider. Green Custard listened to our needs and used their expertise and knowledge to tailor a great solution for us that should last many years to come."

As AWS certified CloudFormation Delivery Partners, we were able to quickly understand the existing software architecture, then plan and execute the migration.

Our knowledge of AWS architectures, and automating both infrastructure and software deployment, were critical to this project.

AWS CloudFormation gives control over infrastructure in exactly the same way that code does. The customer now has full control of their infrastructure and a route forward for the future of Sleuth.

As well as increasing security, governance, and control for the customer, we have reduced their operating costs by 60% compared to their previous solution.

"The customer is now migrated over to a new platform, providing great immediate benefits and a secure future for their education software. This project was worked on remotely in lockdown, but we all still got the buzz from providing a great solution to their problem." - Jonathan Custance, Director at Green Custard
