Heroku: The Good and the Bad

A Cutting-Edge App-Centric Philosophy

  • Heroku additionally provides high availability and elasticity for users. Services hosted on the Heroku platform possess various additional capabilities such as high availability. More surprisingly, applications that satisfy the 12-factor requirements are intrinsically scalable, allowing them to easily address sudden traffic spikes. At that time, this experience was truly cutting edge.

Heroku Is No Longer of Great Value

The Black-Box Runtime Experience

  • On the one hand, there are a few officially supported Buildpacks but many restrictions. For example, the operating system only supports Ubuntu distributions of Linux, and some Ubuntu installation packages cannot be used if they are not installed in the Buildpack. In addition, minor development languages (such as Elixir) are not supported or it is much complicated to use an application when multiple languages are supported in this application.
  • On the other hand, you may be able to customize or find a third-party Buildpack to satisfy your needs, but its stability is not guaranteed. When a problem occurs, it is difficult to locally run a Buildpack to troubleshoot. In addition, error messages from the Heroku platform are not intuitive, and therefore you have to troubleshoot by checking logs, which makes it even more inconvenient to use.
