一覽

Heroku Legacy refers to applications built on old Heroku infrastructure (Dynos v1, Heroku Postgres, abandoned buildpacks). Mastery takes 3-5 weeks. Practitioners earn 10-15% premium because they manage risk-critical legacy apps. Market is shrinking: Heroku shutting down old free tier (2022), sunsetting Heroku CI (2023). By 2026, Heroku = enterprise maintenance, not new development. ~300 companies still running production legacy Heroku. Skill is defensive: keeping old systems alive until migration.

什麼是 Heroku Legacy

Heroku Legacy refers to applications built on deprecated Heroku services: old Dyno types, Heroku PostgreSQL without modern features, custom buildpacks, and unsupported runtimes. These applications still run but are maintained in "freeze" mode, no new features, just keeping the lights on. Heroku itself is not legacy (Heroku still exists), but the infrastructure and patterns used by old apps are obsolete.

❓ 常見問題

Why would a company still use Heroku in 2026?
Legacy code written for Heroku in 2014-2018. Rewriting costs $500K+. Easier to keep paying Heroku ($500-$5K/month) than migrate. Technical debt + budget constraints = legacy Heroku persists.
What happens to my app when Heroku sunsunsets a feature?
Support ends, but app keeps running (usually). Example: Heroku CI deprecated, but apps still deploy via git push. However, new features stop. Eventually, scaling up becomes pain (legacy infrastructure).
How do I upgrade from legacy Heroku?
Options: (1) Container-based Heroku (push Docker image), (2) Migrate to AWS/GCP/Azure, (3) Heroku Private Spaces (more expensive, better isolation). No free easy path.
Can I use custom buildpacks on Heroku?
Yes. Legacy apps often use custom buildpacks to run old Ruby/Node/Python versions unsupported by standard buildpacks. Buildpacks can be fragile and unmaintained. Upgrade dependencies carefully.
How do I scale Heroku Postgres without downtime?
Use Heroku Postgres followers (read replicas). Create follower, promote to primary. Requires downtime or read-only mode. Complex and risky. Most teams just accept the ~5min downtime.
What's the cost of running legacy Heroku?
1 Standard Dyno ($50/month) + Postgres ($50-$500/month depending on size) + add-ons = $200-$1K+/month. AWS equivalents: $50-$200/month. Heroku premium = 5-10x more expensive.
