Q. What do I get with the Engine Yard trial account?
The trial account is a great way to get a handle on what Engine Yard can do for you. It will give you the feel of how our platform automation works and how easy it is to run your application on Engine Yard. The Engine Yard trial comes with one medium compute instance for upto 500 hours free of charge to use how you wish.

Q. What are the primary limitations between a trial account and full account?
The full account comes with different instance sizes, the ability to boot an instance in different AWS regions and Add Ons. When you upgrade from a trial account to a full account you may also be eligible to try our Early Access features and every Engine Yard account comes with Standard Support so you can file a ticket and get support when you need it. Our PANDA team is available to help you get started and answer any questions you have. You can always reach out to us on Live Chat or by creating a support ticket.

Q. Why do I have less than 500 hours in my trial account all of a sudden?
The 500 hours given to all trial accounts are distributed across all the instances you use. So, if you are using 3 instances, your 500 hours will be automatically distributed so you will have 166 hours on each of your instances. You only use hours when an instance is running. So if you remove an instance you will see your hours recalculate to a larger amount.

Q. Why can I only select the east region when configuring my environment?
Trial users may only deploy to the east region. When you upgrade your account, you may select a region that is closer to your customers which can shorten response times. For more information visit: and

Q. What happens to all my trial data once I upgrade my account?
When you upgrade from a trial account to you will need to input a credit card associated with the account for billing purposes. Once this is done you will arrive back at the interface of your account. If you had instances running on your account they will continue to run and all your data will still be intact. Upgrading your account only unlocks the full features of an Engine Yard account such as differing service regions and access to our third party Add Ons. If you had stopped your instances from running prior to upgrading your account all your data will be stored in a snapshot. Once you’ve upgraded you will be able to boot up your instance from a snapshot and all your application and data will be available once the instance is back online. For more information on upgrading your trial account visit:

Q. What happens to my trial data when my trial ends and I have not upgraded my account?
If your trial ends and you haven’t upgraded to a full account yet, Engine Yard will hold your application and data for 90 calendar days from the date your trial ended. You may convert the expired trial account to a full account and reinstate the application and/or data at any time within those 90 days. You may also download your data at any time within the 90 days. After 90 days, unconverted applications and data may be deleted.

Environment setup, scaling, configuration, deployment

Q. How do I add more users to my account?
You can add or remove team members from the account management screen in the product interface. Click on the ‘Account’ link on the top right of the Engine Yard interface, click the ‘Account Settings’ button, and at the bottom of the page you can add members to your account. Type in the email address of the person you want to give access to, then click ‘Add User’. More info:

Q. I currently have one single instance. Why can’t I add more instances to my environment?
With a single instance, your application and database are combined within the same instance. In order to add more instances or to create a cluster, you will need to stop the current instance (via the ‘Stop’ button in the interface). Once the instance has stopped you can use the ‘Boot’ button to restart it. From there you will be able to change your environment setup to one of the other pre-configured options that have dedicated application and database instances and boot that configuration. Moving away from the single instance option will allow you to add more instances in the future once the application and database are separated. You can follow this simple tutorial:

Q. My deployment was successful but when I click the ‘visit’ link there was an error message. What should I do?
If you are in the trial you can always Live Chat with one of our Deployment Engineers from within the interface. The Deployment Engineers can help troubleshoot what went wrong with your deployment. In the interface there is also a location to place a support ticket in the Engine Yard queue. Adding a ticket to our queue will ensure that someone looks at the problem and gets it resolved quickly. To troubleshoot some of your issues it is best to SSH into your environment directly and look at the log files. Here is a great documentation about how to set up your SSH Key and another explaining the log files:

Q. Can we use SVN(Subversion) instead of Git?

Q. Do you handle DNS? How do I point Engine Yard to my own domain name?
Engine Yard does not manage DNS. In order to have your application point to a specific domain you will need to set it up with one of many DNS providers. The following link is a tutorial for setting up your domain using DNSimple as an example:

SSH Access

Q. How do I SSH into my instance?
First you will need to set up your SSH keys locally, on Engine Yard, and within your application environment. You can do this by following the 4 steps outlined here:

After completing the above steps, you have two options for connecting to your instance via SSH. First, you can connect to your instance via your favorite SSH client (terminal (by way of OpenSSH), putty, etc). Or, you can click the SSH link under Application Instances which is on your Engine Yard interface. For a more in-depth tutorial visit:

Q. Why am I not able to SSH into my instance after adding my SSH key?
If you cannot SSH into your instance after you added your SSH key you may still need to apply the SSH key to your environment. By hitting the ‘Apply’ button in your instance it will apply configurations to your environment. One of these configurations will check that an SSH key has been added to your profile and apply it to your environment. For more information on what the ‘Apply’ function does please visit:

High Availability

Q. High availability is very important for my application. What sort of precautionary measures does Engine Yard offer to protect my application?
High availability and uptime are always a concern. Engine Yard recommends our customers distribute their application and database replicas across AWS EC2 Availability Zones. When adding new replicas, Engine Yard will automatically distribute them across different availability zones within a given region. However, you always have the ability to control the distribution yourself. For step-by-step guidelines to do this for your own application visit:

Q. How can I update my credit card? (Admins only)
To update your information, please login into your account and select:

Account ---> Account Settings ---->Payment Information

If you're still having trouble, please try these troubleshooting tips:

Be sure that you are not entering your credit card's "valid from" date in the expiration date field by mistake.

If you are updating your credit card info with a new card's information, please be sure that you have already activated that new card by calling your credit card company before you add the information.

If your billing information is accurate, there may be some other issue causing the transaction to be declined. In such cases, we recommend that you inquire directly with your bank or credit card provider. They will be able to determine the exact cause of the failure by reviewing the transaction history associated with your card. Once you have established the cause of the problem, update the specific information on your account page.
