Dyno types refer to different kinds of dynamometers used to measure power and torque, or, in the context of Heroku, different types of application containers. Let's explore both:
1. Automotive Dynamometers (Dynos)
These machines measure the power and torque output of engines and vehicles. Several types exist, each with strengths and weaknesses:
- Roller Dyno: Ideal for general chip tuning and dyno days. They're common and relatively affordable.
- Hub Dyno: Best suited for professional motorsport and extensive tuning jobs on standalone ECUs (Engine Control Units). They offer high precision.
- Engine Dyno: Primarily used by engine builders for rigorous endurance testing and highly accurate measurements.
The type of dyno used significantly impacts the results. Different dynos measure power differently, making direct comparisons between results from different types unreliable. For example, a hub dyno might show slightly higher or lower numbers than a roller dyno for the same engine.
2. Heroku Dynos (Application Containers)
In the Heroku cloud platform, a dyno is a container that runs your application code. Heroku offers various dyno types, impacting pricing and resources:
- Heroku offers several "Common Runtime" dyno types, often referred to as dyno "sizes." Larger, more expensive dynos provide greater resources like memory and processing power. These sizes are designed to meet different application needs.
- Performance, Private, and Shield dyno tiers offer even larger dyno types, tailored to more demanding applications with specialized requirements.
- Worker dynos perform background tasks, while one-off dynos are temporary for specific commands.
The choice of dyno type significantly influences the cost of running your application on Heroku. Larger dynos are more expensive but provide more resources.
The type of dyno you select in Heroku depends on the demands of your application. Choosing the right dyno size balances performance and cost-effectiveness.
