    <p>Just some observation:</p> <p>a. AppScale is a thin wrapper around other technologies (<a href="http://appscale.cs.ucsb.edu/infrastructure.html" rel="nofollow">runtimes</a>, <a href="http://appscale.cs.ucsb.edu/datastores.html" rel="nofollow">datastores</a>), so in general it's as reliable as those underlying parts are. For a small non-mission-critical website is IMO reliable enough. Btw, the memcache 1MB limit is per-object, not per-memcache. So I suppose you could break it up into multiple smaller objects.</p> <p>b. I don't have experience with CloudFoundry, but they do say they are "beta" and they do not have SLA: <a href="http://support.cloudfoundry.com/entries/20971351-cloud-foundry-sla" rel="nofollow">http://support.cloudfoundry.com/entries/20971351-cloud-foundry-sla</a>\</p> <p>c. I'd guess a few hours a week. ESB is a disk-based service so you should not be loosing data with it. But you can still do incremental backups of ECB to S3. There are many solutions that do it automatically, for example: <a href="http://www.stardothosting.com/blog/2012/05/automated-amazon-ebs-snapshot-backup-script-with-7-day-retention/" rel="nofollow">http://www.stardothosting.com/blog/2012/05/automated-amazon-ebs-snapshot-backup-script-with-7-day-retention/</a></p> <p>d. IMO EC2 is the most mature with the most tools available. Note that AppScale is just a wrapper - you can deploy it to EC2. Dev environment (Eclipse+Windows) has nothing to do with deployment environment (Usually Linux, can also be Windows on EC2).</p> <p>e. Personally I'd recommend staying with GAE (= option 1). IMHO anything else would be less reliable and more costly (due to setup/support costs, not even comparing base service costs).</p> <p>Btw, if you are getting OutOfMemoryErrors you should really review your code. Where do you keep massive amounts of data in memory?</p>

    1. COPeter, thanks for your comments. "So I suppose you could break it up into multiple smaller objects." <-- yes, and I can break my datastore up into smaller objects, but that will increase data model complexity and the number of requests. "Where do you keep massive amounts of data in memory?" <-- nowhere except the memcache, the application is stateless. "Dev environment (Eclipse+Windows) has nothing to do with deployment environment." <-- I want to test it on my local system before deploying to cloud. If all docs assume my local system is Unix, that makes my life more difficult.

    2. COYes, entity size and memcache object size are limited to 1Mb. What structured data do you store that is bigger than this? If you store binary or large text data you should use blobstore.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
