Limits and Instance Types

Instance Types

The memory, vCPU, and disk space for Containers are set through predefined instance types. Six instance types are currently available:

Instance Type	vCPU	Memory	Disk
lite	1/16	256 MiB	2 GB
basic	1/4	1 GiB	4 GB
standard-1	1/2	4 GiB	8 GB
standard-2	1	6 GiB	12 GB
standard-3	2	8 GiB	16 GB
standard-4	4	12 GiB	20 GB

These are specified using the instance_type property in your Worker's Wrangler configuration file. Looking for larger instances? Give us feedback here and tell us what size instances you need, and what you want to use them for.

Note

The dev and standard instance types are preserved for backward compatibility and are aliases for lite and standard-1, respectively.

Limits

While in open beta, the following limits are currently in effect:

Feature	Workers Paid
GiB Memory for all concurrent live Container instances	400GiB
vCPU for all concurrent live Container instances	100
TB Disk for all concurrent live Container instances	2TB
Image size	Same as instance disk space
Total image storage per account	50 GB 1

Footnotes

1. Delete container images with wrangler containers delete to free up space. Note that if you delete a container image and then roll back your Worker to a previous version, this version may no longer work. ↩
