IronWorker

It's simple but scalable, the support is very good. When setting up I had a lot of questions and they respond quickly. I like the interface, the ability to easily see exactly what is contained in each request is great and the API is straightforward.

There is not much middle ground on the pricing, it's either an opening price point plan with more limited features, and then the next level jumps up significantly in price. I am using this for an app that is not processing a up huge volume of traffic so I am able to get by with the features on the lowest price point plan, but I would like something offered in the middle that doesn't jump up in price so steeply. I should mention I am using the worker via the Heroku app.

The only other negative is that the worker has gotten hung up on me a couple of times but it has only happened minimally and they are quick to resolve once I report it.

I love that Iron Workers can now be loaded using Docker containers! Speeds up release time exponentially and makes testing significantly easier since my local environment is always the same as the production environment. It is also fairly easy to push workers directly from my code base (PHP) or create crons that are run from the command line.

The docker documentation is poor. Each time I needed to launch a worker in a new environment, I needed to talk with Iron support team to help them build the Dockerfile. IronWorker doesn't appear to be primary product of Iron either (that would be IronMQ), so updates to the platform are somewhat infrequent.

It is relatively low effort. Solves the retry to send this to a third part some what simply.

Testing is a pain. Getting the correct dependancies installed can feel like a lottery. It feels like it has been abandoned in terms of updates.
