# Containers

> Learn what a container is, how long containers last, and the different types of containers available for the different plans.

A **container** is the virtual environment where Julius is manipulating your [files](https://julius.ai/docs/get-started/files) to execute code, perform analysis, and generate visualizations! Each container acts like a remote computer in the cloud, and like a computer a container has dedicated resources like RAM and CPU.

### Container Persistence

By default all free and paid user containers are live for up to 1 hour of inactivity. After 1 hour of inactivity, the container is spun down.

### Types of Containers

There are three types of containers -- **Standard**, which is included in all plans, and **Longer Lifespan** and **Memory Boost** which are available on the Pro plan and higher.

| Container Type  | Container Persistence | Amount of RAM | Plan Type           |
| --------------- | --------------------- | ------------- | ------------------- |
| Standard        | 1 Hour                | 8 GB          | All plans           |
| Longer Lifespan | 3 Hours               | 8 GB          | Pro plan and higher |
| Memory Boost    | 1 Hour                | 32 GB         | Pro plan and higher |
