Adobe I/O Runtime: Frequently Asked Questions

Getting Access

How can I get access to I/O Runtime?
Runtime is now part of App Builder. There are more details here about how to get access.

Supported Programming Languages

Which languages are supported in I/O Runtime?
For now, Adobe I/O Runtime only supports Node.js. We might add support for other languages in the future.

Node version 18 - Default Image

The NPM modules available with this image can be found here.

We encourage you to always update your actions to the latest version in order to take advantage of pre-warm containters feature.

Older Versions

When a new Node version is added to the system, the old versions are still available. This means that your actions will still work. However, you won't be able to create new actions with these versions. We encourage you to always update your actions to the latest version in order to take advantage of the pre-warm containers feature.

Networking

Are there any restrictions when it comes to ports and outbound connections?

When retrieving data from some external systems your code might need to connect to a SFTP server, SMTP server, or HTTP service. As long as that system uses one of following ports, your code should work fine:

21, 22, 25, 53, 80, 123, 143, [200-299], 389, 443, 445, 465, 587, 636, 1433, [2000-2999], 3000, 3306, 4242, 4317, 4343, 5400, 5432, 5671, 5672, 6061, 6062, 6379, 6380, 6651, 8000, 8020, 8080, 8085, 8088, 8089, 8300, 8500, 8600, 9090, 9092, 9093, 9094, [9096-9352], 9354, [10000-20000], 27016, 27017, 27018, 27019, 30303, 50010, 60020.

Multiple Region Support

Where we execute your actions I/O Runtime runs in multiple regions. We deploy your code in all regions and execute it in the closest region to the caller (latency-based routing). You can't restrict the execution to a specific region only.

You can find more information about the regions and how you can check where your actions are being executed here - Multiple Regions.

System Limits

Which limits are imposed onto actions?
All available limits (and the default values) are listed here: System Settings. Notable limits are the timeout for functions and the maximum payload that can get posted to a function.
