About Heroku Runtime

A fully managed environment for running apps that provides release management, SSL, security patching, logging, networking, and container orchestration.

🛠 Heroku Runtime's Features

What can developer do with Heroku Runtime

Smart containers

The Heroku platform runs your apps inside smart containers called dynos. Dynos work in tight coordination with the dyno manager to provide a range of benefits to your app like security, isolation, and scalability.

Container orchestration

The dyno manager, a part of the Heroku Runtime, coordinates and manages all your app’s dynos. Failed dynos are cycled and all components are reset and refreshed upon a redeploy. If there are any failures in the underlying hardware, all your dynos are moved to a new location without any manual intervention.

Log aggregation

The Heroku Runtime aggregates logs from the output streams of your app, system components, and backing services and sends them into a single channel using Heroku’s Logplex. Heroku aggregates three categories of logs for your app: app logs, system logs, and API logs.

HTTP routing

A set of routers automatically routes HTTP requests from your app’s hostname(s) to your web dynos. The router uses a random selection algorithm to distribute traffic across your web dynos.

Release management

With every code deploy a new release is created and stored on Heroku. You can list the history of releases, and use rollbacks to revert to prior releases for backing out of bad deploys.

Configuration management

Configuration may vary between different environments. Heroku uses config vars to keep track of environment configurations. Each time a config var is updated, it creates a new release so you can can roll back to any previous release to have the config vars restored.

SSL and Certificate Management

Heroku SSL and Automated Certificate Management are included at no additional charge on any app using paid dynos. The Heroku router terminates SSL for your app’s custom domains. With Automated Certificate Management, a TLS certificate is generated for your custom domains automatically.

Horizontal and vertical scaling

You can horizontally scale any app running on Standard or Performance dynos by increasing the number of dynos from the Heroku Dashboard or CLI, or change dyno types to vertically scale your app by running on dynos with more CPU and memory capacity.

Deploy with Docker, run on Heroku

You can choose to deploy pre-built Docker images via Container Registry, or have Heroku build your Docker images from your Dockerfiles. Take advantage of Heroku's container orchestration, high productivity developer experience, and managed infrastructure.

💰 Heroku Runtime's Pricing

How much does Heroku Runtime cost?

Heroku runs your app in lightweight, isolated Linux containers called "dynos."
