Wellola – Next generation patient communication 

Discover how Wellola transformed their healthcare solution through a SaaS cloud transformation project

Case Summary

Wellola provide a hosted SaaS service for clinics (focusing on health and mental health in particular) that allow them to manage client interactions including video consultations, secure messaging and face-to-face scheduling services through both browser based and mobile application interfaces.

The business is growing, and they are now starting to engage with larger organisations including government health providers, however, to succeed with these customers and continue to grow, Wellola must be able to demonstrate an enterprise class solution that complies with regulatory standards and data protection legislation. A key selling point for their solution is how it helps address GDPR concerns as it provides a single, properly managed means for Wellola customers to interact with their clients and avoids issues that may arise with using SMS, email etc.

The Wellola platform is delivered using AWS cloud hosted systems with a mix of both single and multitenant instances with EC2 as the primary service used. Wellola understand how AWS provides a hosting service that meets the highest security and data protection standards, but to deliver their solution and their application, its use of AWS services and the management procedures and processes that surround it, must also meet the required standards. To achieve this, Wellola wanted to engage a certified AWS partner to provide direction, assistance and services to support their team in evolving and operating their platform.  

Deloitte worked with the Wellola team to complete a platform review focusing on the business services and technical decisions that they needed to make as part of the SaaS transformation. Using the AWS SaaS enablement framework (SEF) Deloitte provided input and direction on the security and organisational design, tenant isolation and tenant on-boarding approach that would allow Wellola to achieve their goals. The approach looked in depth at all business interfaces, client – mobile application, clinician – web browser, clinic reception/admin – web browser and business service API’s.

To ensure that the solution was designed and built in accordance with best practice, Deloitte leveraged the Well-Architected framework and guided the Wellola team through an analysis and design workshop on how to better use AWS services to achieve reliability, security, operational excellence, performance and cost efficiency for their SaaS solution. This enabled us to derive a conceptual architecture for the proposed solution incorporating the key recommended improvements, a service model design and a solution that matched their complex security requirements.

With only minor changes to the application, the team transformed the solution to a multi-AWS account architecture with increased deployment automation and enforcement of multiple security controls built on the AWS serverless platform that can be scaled to support single and multi-tenant configurations. This solution underpins the Technical and Organisational measures enabling Wellola to demonstrate compliance with best practices for both small and large customers.
