FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Rate limit
The Cloudwatch Logs API requires a sequence token to be send with the messages to a log stream. This token is returned after a transfer of messages to the log stream to be used at the next transfer. For multi-process systems this is hard to handle.
So AWS Cloudwatch Logs does not support multiple processes writing to the same log stream at the same time. Their official approach is to create a separate log stream for each process on each instance. But think of PHP-FPM with dynamic childs on several instances. This would end up in thousands of abandoned log streams in a log group after a while. Empty log streams are not deleted automatically and remain in the log groups. They do not cost anything, but make log groups very messy.
Our approach is to create only one log stream per instance. To be able to send log streams from multiple processes at the same time, the current sequence token of the log stream must be queried before each transmission. But the AWS Cloudwatch Log API has a rate limit of 60 requests per second for this type of request.
In order to avoid running into this rate limit, it is highly advisable to pass only those logs directly to Cloudwatch Logs that happen rarely and are important. For example Warnings and Errors.
In large infrastructures with many simultaneous processes with a high log load, it is still better to use file logging and the Cloudwatch Log Agent, as this is only a single process.
Maybe this will change in the future.
