Introduction

Epycbyte Functions allow you to define serverless functions that can be triggered by specific events. These functions run in isolated environments, and their performance heavily depends on the allocated memory and CPU resources. Proper configuration of these resources ensures efficient execution and cost management.

Considerations for Memory Configuration

• Performance: Allocating sufficient memory ensures your function has enough resources to handle tasks without delays.
• Cost Efficiency: Excessive memory usage can lead to higher costs, so balancing resource allocation is essential.

Setting Default Function Memory/CPU Size

Epycbyte allows you to set default memory and CPU settings for your functions. These defaults apply when creating new functions or updating existing ones.

Steps:

1. Navigate to the Epycbyte Dashboard.
2. Select the appropriate project and function.
3. Under "Memory & CPU," adjust the slider to allocate the desired resources.
4. Save your changes.

Customizing Function Memory/CPU Settings

For more granular control, you can specify memory and CPU settings directly in your code or using Epycbyte's CLI tools.

Example (using epycbyte.json):

{
  "functions": [
    {
      "name": "my-function",
      "memory": "128MB",
      "cpu": "0.5"
    }
  ]
}

• Memory: Specify the required memory in MB or GB.
• CPU: Allocate a fraction of a CPU core (e.g., 0.5 for half a core).

Viewing Function Memory Sizes

To check the current memory and CPU settings:

1. Open the Epycbyte Dashboard.
2. Select your project and function.
3. Under "Memory & CPU," view the allocated resources.

Memory Limits

Epycbyte imposes limits on the maximum memory and CPU allocation to ensure fair usage and prevent abuse. Exceeding these limits may result in errors or service interruptions.

• Max Memory: Typically capped at 4GB per function.
• CPU Limits: Varies by plan, with higher-tier plans offering more cores.

Pricing

While memory/CPU size isn't explicitly billed, it directly affects Function Duration. Epycbyte charges based on the total execution time (measured in GB-Hours). For example:

• 1GB of memory and 1 second of runtime = 1GB * 1s / 3600 ≈ 0.0002778 GB-Hours.

To minimize costs, optimize your functions to use resources efficiently.

By following these guidelines, you can configure Epycbyte Functions to meet performance needs while managing costs effectively.
