AEM Site Performance Optimization

Improving performance, scalability, and maintainability of enterprise AEM platforms.

Service: Performance & Optimization Platform: AEM Sites Focus: Scalability & Maintainability Tools: SonarLint, Checkstyle, PMD

Background

We often engage with clients who already have a live AEM platform developed by a third-party agency, but are experiencing performance issues, scalability challenges, or difficulties upgrading to newer AEM versions.

In such cases, our role is to assess the existing system, identify performance bottlenecks and technical risks, and provide a clear roadmap for improvement.

Task

The objective was to perform a comprehensive analysis of the client’s platform — including the site architecture, infrastructure setup, and codebase — and provide a detailed report of performance issues, scalability risks, and modernization recommendations.
