Edge – a brand new customer-loyalty service with Plexian

Flexible and cost-effective way with AWS


A brand new customer-loyalty service with Plexian

Plexian is a Malmö-based company that is developing a brand new service and solution, a “Digital wallet” which has the mobile benefits of an app combined with the functions of a bank card – everything is built on Plexian’s platform “Edge”. Through their self-developed solution Edge is Plexian focusing on creating unique solutions of loyalty together with strategic partners. 

Flexible and cost-effective way with AWS

With the solution Edge is Plexian filling a gap in the market for solutions of loyalty and there is an attractive market with great potential. To be able to offer the best service they wanted the solution to be scalable and technically mature. A number of suppliers were involved in the selection process but the choice fell on AWS’s platform where the benefits were many; they offered a flexible and scalable solution with great maturity in AWS’s services compared to the competitors, you also got access to a variety of technical solutions. 


The challenge for Plexian was to keep the costs down at the same time as the solution should be scalable and in the forefront of the technical, this was successful according to Markus Bergkvist, Solutions Architect. Markus came along early on in the project and has helped Plexian build on the APIs and the basic structure that already existed, as Campaign Manager and Cashback Accounting. Markus has also developed the back-end system that handles transactions and cashbacks.

We have worked very agile and have managed to keep the spendings down, no hardware has needed to be purchased because of the fact that everything is serverless. It is a great advantage with AWS and we have been able to turn quickly during the project when needed, simply immense flexibility, continues Markus Bergkvist, one of the 4 developers in the project.   




What techniques have been used in the project?

To ensure an AWS environment that can safely be able to grow and easily be monitored was AWS Control Tower used where you, using AWS SSO (Single Sign-on), can make sure that the right user gets access to the right services and data. 

To the development of infrastructure were AWS SDK (Cloud Development Kit) used. An AWS CodePipeline was set up to handle CI/CD and to support mobile apps were AWS Amplify used.

Amazon API Gateway and AWS AppSync in backend

The Backend is fronted by Amazon API Gateway and AWS AppSync where the logic is managed by Lambdor and the data is saved in DynamoDb and Aurora Serverless. The flow itself is handled by AWS Step Functions.

The solution is Serverless, which means that Plexian does not need either its own hardware or administer software that is not directly related to their business logic. Besides, the publication of new software and monitoring is fully automated. The system is built and adapted for Plexians environment and there is nothing like it on the market.

Thanks to Purple Scout have we been able to find new and modern solutions with AWS, who help us on the market and allows us to grow. The solution “Serverless” is both cost-effective and very scalable, which was our top priority during the beginning of the project.” says Peter Kaiser, CFO Plexian.
