Trusted Tomcat to Heroku Migrations – Fixed Scope, Senior Engineers
Yes, migrating Apache Tomcat to Heroku is a well-understood project. Our senior engineers handle code adjustments for ephemeral architectures, port bindings, and security integrations — on a fixed scope and timeline.
The lowest-cost way off Apache Tomcat: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support Apache Tomcat → Heroku after migration
- ✓Fixed-scope migration – no hidden surprises
- ✓Senior platform engineers refactor your code
- ✓Eliminate server administration overhead
- ✓Adapt to Heroku's ephemeral file system
- ✓Integrate on-prem security into cloud-native auth
- ✓Post-migration Heroku optimization included
Local disk write dependence
Your Tomcat app writes to local storage, but Heroku's file system is ephemeral. We refactor to cloud storage like S3 or RDS.
Hardcoded ports and IP bindings
Legacy Java configs with hardcoded ports or IPs break on Heroku. Our engineers rewrite server.xml and application configs.
Deep on-prem security integration
LDAP, Active Directory, or custom auth tied to local hardware. We migrate to cloud-friendly identity providers.
Apache Tomcat → Heroku migration — your questions answered
How long does a Tomcat to Heroku migration typically take?+
Most migrations complete in 1-2 months with 1-2 of our senior engineers working full-time on your code and configuration.
What about apps that write to local disk? Can I still migrate Tomcat to Heroku?+
Yes. We refactor your application to use cloud-native storage (e.g., Amazon S3, Heroku Postgres) so it works with Heroku's ephemeral file system.
Can I deploy my existing Tomcat WAR file to Heroku unchanged?+
Often not. Heroku uses a different runtime environment. We adjust your WAR, re-configure ports, and handle session clustering to make it deploy.
How do you handle hardcoded IP addresses or port numbers in my Tomcat config?+
Our engineers audit your server.xml, web.xml, and application code for hardcoded bindings, then replace them with environment variables and Heroku's port mapping.
