How My VPA Unified Access on AWS Keycloak

my-vpa GmbH

Our partnership with My VPA GmbH began over five years ago when the company came to Perfsys with a specific challenge: to update and centralize its identity management system across various SaaS components. My VPA, a prominent provider of virtual personal assistance services, was using a custom authentication system developed in PHP and supported by a MySQL database. As their platform grew, new products—including the primary web application, ownCloud for file sharing, and internal management tools—required a cohesive and secure single sign-on (SSO) solution. To address this need, Perfsys created and implemented a Keycloak-based identity and access management (IAM) system hosted on Amazon Web Services (AWS). This architecture was set up on EKS (Kubernetes), utilizing RDS MySQL, EC2 instances, and Application Load Balancers to ensure scalability, performance, and high availability. A significant milestone in this project was the creation of a custom user federation provider—a specialized Keycloak extension that directly integrated Keycloak with My VPA’s existing MySQL user database. This innovation enabled My VPA to keep all existing accounts and passwords without needing to migrate or interrupt services, facilitating a seamless transition to centralized authentication. Since the initial rollout, Perfsys has consistently supported, upgraded, and optimized My VPA’s Keycloak infrastructure. The system has been enhanced through various Keycloak updates (from version 3.1 to 23), accompanied by regular maintenance cycles for Kubernetes and EC2, proactive monitoring, and security upgrades. It has been operational for over five years, scaling from hundreds to thousands of users, maintaining robust performance, and cutting IAM-related costs by almost 90% compared to SaaS options. Currently, Perfsys continues to be a vital technology partner for My VPA, ensuring their system remains secure, up-to-date, and cost-efficient as their digital services expand.

AI Mental Health Assistant MVP on AWS Bedrock

i Got This!

Perfsys collaborated with UK startup i Got This! to create an investor-ready minimum viable product (MVP) for an AI mental health assistant, utilizing Amazon Bedrock. Founded by Ann Watson, who draws inspiration from her own experiences in education and caregiving, the goal was to develop an empathetic, secure, and scalable AI tool to assist users with stress, anxiety, and emotional well-being. The initiative focused on blending AI advancements with stringent data protection and user safety, crucial for mental health tools. Perfsys completed the MVP in three agile stages, evolving from a third-party avatar prototype to a fully serverless AWS architecture. Major accomplishments included a 90% cost reduction through the separation of avatar UI from AI functionality and the transition to AWS Bedrock, a scalable and investor-friendly technology stack utilizing Amplify, Cognito, API Gateway, Lambda, DynamoDB, S3/CloudFront, and Bedrock's ethical AI design with safeguards to prevent self-harm and suicide. Additionally, the solution offered personalized user sessions through Cognito metadata for contextually aware AI interactions. The final product not only met functional and security standards but also positioned the startup for investment, with a clear strategy for growth. Ann Watson commended the partnership, stating that Perfsys felt like an in-house team and awarded them a perfect score of 5.0/5 on Clutch for quality, communication, and delivery. This case study showcases how Perfsys empowers mission-driven entrepreneurs to transform innovative concepts into safe and scalable AI solutions that garner funding and create meaningful social change, leveraging the robust capabilities of AWS Bedrock.

AWS Migration & CI/CD Automation

Cadstrom

A rapidly expanding B2B software company collaborated with Perfsys to transfer its infrastructure from Microsoft Azure to Amazon Web Services (AWS), successfully creating a secure, compliant, and scalable platform in preparation for SOC2 certification. Within two months, Perfsys transitioned 27 cloud applications, automated deployments, and assisted more than 200 clients in saving valuable operational time. The previous Azure infrastructure posed limitations on scalability, delayed releases, and complicated access controls. Perfsys restructured the entire architecture in five crucial phases: Discovery & Planning, AWS Organization Setup, Infrastructure Deployment, CI/CD Automation with ECS, and Production Launch. Key achievements included a multi-account AWS environment with centralized logging and Single Sign-On (SSO) via IAM Identity Center, Terraform-based automation, and CI/CD pipelines linked with Azure DevOps and AWS ECS. The outcome: 27 applications migrated in eight weeks, complete infrastructure automation, reproducible environments, and a SOC2-ready AWS setup with enhanced security and scalability. This project exemplifies how Perfsys assists B2B software teams in upgrading their cloud systems, streamlining their delivery processes, and establishing secure, efficient AWS environments designed for growth.
