Performance

ColdFusion Performance Tuning: Slow Queries, Caching and Memory Leaks

Most slow ColdFusion apps are slowed by database queries, missing caching, JVM memory pressure or slow external calls, not the engine. Measure first with an APM like FusionReactor, then parameterize and index queries, cache stable data, fix memory leaks in shared scopes and put timeouts on every outbound call.

Is ColdFusion Dead? Where CFML Stands in 2026

No. Adobe released ColdFusion 2025 with support expected to around 2030, the open-source Lucee engine is actively maintained, and thousands of business-critical apps still run on CFML. The real risk is not the language but unsupported versions, untested code and a shrinking pool of developers who know it.

Security

ColdFusion Security Hardening Checklist

Secure a ColdFusion server by running a supported, fully patched version, applying Adobe's lockdown guide, keeping the administrator off the public internet, running as a low-privilege account, and fixing code-level risks like SQL injection, XSS and unsafe file uploads. Then monitor, back up and review it regularly.

Upgrading to ColdFusion 2025: Checklist and Breaking Changes

Upgrading to ColdFusion 2025 means checking Java and OS compatibility, installing only the packages your code uses, reviewing Adobe's deprecated and removed features, testing changed security defaults, then running a full regression test on a copy of production. Skipping versions is normal if the audit covers every change in between.

Migrating ColdFusion to AWS: A Step-by-Step Guide

Moving a ColdFusion app to AWS means inventorying the current server, choosing EC2 or containers, moving the database to RDS and files to S3, recreating datasources, mail and scheduled tasks, then testing side by side before switching DNS. Most of the risk sits in planning, not the copy.

ColdFusion Hosting in 2026: Your Options Compared

ColdFusion apps run on shared CF hosting, a VPS or dedicated server, or in the cloud on AWS or Azure, either on virtual servers or in containers. For most business apps, a cloud server or container you own gives the best mix of control, cost and security. Shared hosting suits only small, low-risk sites.

Lucee vs Adobe ColdFusion: Cost, Compatibility and When to Switch

Lucee is a free, open-source CFML engine; Adobe ColdFusion is a commercial product with paid licenses and vendor support. Most everyday CFML runs on both. Lucee usually wins on cost and container-friendliness; Adobe wins when an app depends on Adobe-only features like advanced PDF services or needs vendor-backed support.
