Technical Assessment Requirement

• Java is required as coding language
• A service should be created to generate a pizza order message with name, quantity and price (the values used do not matter) and send that message to the second service.
• A service should be created to receive that order message and store it in a database.
• The database does not need to be persistent, H2 can be used.
• Calls should be secured.
• Calls between services should use REST.
• Logging / documentation and testing are expected as part of the solution.
