Google App Engine Leaving Preview - Google

Dear Google App Engine Application Administrator,

In May at Google I/O we announced that Google App Engine would be leaving
Preview status later this year. As part of Google's long-term commitment to
App Engine, we are also updating our policies, pricing and support model to
reflect its status as a fully supported Google product. We plan to roll this
out in the second half of September but we wanted to let you know what this
will mean for you and your App Engine applications. Please be aware that the
timeline may change, but you can keep up to date on our progress on the App
Engine blog. We plan to send a second email once the new pricing is in effect.

For all paid applications using the High Replication Datastore (HRD), we
will be introducing a new 99.95% uptime SLA. The current draft form of the
SLA can be found at http://code.google.com/appengine/sla.html. For apps not
using HRD, we will also soon release a tool that will assist with the
migration from Master/Slave (M/S) to HRD (you can sign up to be in the
Trusted Tester for the tool here: http://goo.gl/3jrXu). We would like to
emphasize that the SLA only applies to applications that have both signed up
to be a paid App and use the HRD Datastore.
App Engine has a 3 year deprecation policy. This policy applies to the
entire App Engine platform with the exception of "trusted tester" and
"experimental" APIs. This is intended to allow you to develop your app with
confidence knowing that you will have sufficient notice if we plan to make
any backward-incompatible API changes that will impact your application.
We will be updating the Terms of Service with language more geared
towards businesses. A draft of the new ToS can be found at
http://code.google.com/appengine/updated_terms.html.
We are introducing new Premier Accounts that will have access to
Operational Support, invoice-based billing, and allow companies to create as
many applications as they need for $500 per account per month (plus usage
fees). If you are interested in a Premier Account, please contact us at
[email protected].


We will be moving to a new pricing structure that ensures ongoing support of
App Engine. Details of the new structure can be found at
http://www.google.com/enterprise/cloud/appengine/pricing.html. This includes
lowering the free quotas for all Apps. Almost all applications will be billed
more under the new pricing. Once App Engine leaves preview this pricing will
immediately go into effect, but we've done a few things to ease the
transition:

If you sign up for billing or update your budget between now and October
31st we will give you a $50 credit.
In order to help you understand your future costs we are now providing a
side by side comparison of your old bill to what your new bill would be. You
can find these in your Admin Console under "Billing history" by clicking on
any of your "Usage Reports". Please review this information. It's important
that you study this projected billing and begin any application tuning that
you want to be in effect prior to the new bill taking effect.
We have created an Optimization Article to help you determine how you
could optimize your application to reduce your costs under the new model.
We have created a Billing FAQ based on the questions many of our
customers have had about the new pricing model.
The new pricing model charges are based on the number of instances you
have running. This is largely dictated by the App Engine Scheduler, but for
Python we will not be supporting concurrent requests until Python 2.7 is
live. Because of this, and to allow all developers to adjust to concurrent
requests, we have reduced the price of all Frontend Instance Hours by 50%
until November 20th.
Finally, if you have any additional questions or concerns please contact
us at [email protected].

In order to graduate from Preview status, we've made and continue to make
large investments in platform features, scalability, and stability that your
applications will benefit from. Thank you for your support, commitment, and
feedback on App Engine as it has developed. We look forward to working with
you for years to come!
Thank You,
The App Engine Team
