# Server Machines on Launch

Server machines determine the CPU and memory that Contentstack Launch allocates to your functions at runtime. Selecting the right machine type ensures your workloads have enough resources to run efficiently.

## Available Machine Types

The following machine types are available on Launch:

**Server Machine Tier**

**vCPU**

**Memory**

**L1 (Default)**

0.5 vCPU 

1 GiB

**L2**

1 vCPU

2 GiB

**L3**

2 vCPU

4 GiB

Deployments start with the **L1 machine type by default**, but customers can scale to **L2** or **L3 tiers**, enabling support for high-traffic, large-scale, and resource-intensive workloads.  
To request a tier change, contact your Contentstack account representative.
