Google App Engine Reviews

- A very good platform for those applications that store something and retrieve it back. - Google takes care of deploying the code to the clusters, monitoring, failover, and launching application instances as and when necessary. This takes a lot of the administrative work off the user. - Easy and cheaper (in the short term) - Unlimited scalabity to your application, and scales with demand. - GAE supports MySQL db as well. - App Engine doesn't provide you with the flexibility to use an equivalent service if you need to pick something else for your app.

- Developers have read-only access to the filesystem on the Google App Engine. - GAE is not suitable for CPU intensive calculations. - You cannot produce a social graph using Google app engine. - Once you think of migrating out of the AppEngine world, you'll face a lot of problems. For example, having to change your code to use your own datastore, task queues, and other services. If your application is fairly large, this will be a very difficult process. - Since the backend is completely manage by Google, you don't have control over the environment your application runs in. - Apart from the free space and to build some "Hobby" websites, Google App Engine is not the place java guys should look in as Java is quite heavy on memory front.

Overall a good platform for running small applications that basically deals with storing and retrieving data from backend. Since the backend is handled by Google, you get a scalable app platform, but at the cost of losing control over the backend environment. You cannot tweak the backend and you just have to leave with whatever Google has to offer.

Zero maintenance cost for web servers Reliable for scalability Free basic account with limited quota for trial Suitable for startups with limited users and limited resources

No filesystem access More expensive than the alternate options if a product/service has a lot of users Language support limited to Java and Python Database options limited to MySQL and Google data store

I have been using it for a startup for over an year. Initially it was great, but with an expanding user base, it makes more sense to host my own servers.

We have five Google App Engine applications deployed on private clouds, and we have some deployed on public clouds. We use both Google and Microsoft.

Google App Engine's most valuable feature is self-management. You do not have to manage the infrastructure underneath where all the functions are happening, such as load balancing deployment and version management, they are managed by the system itself.

Google Cloud has a number of products that complement each other in being able to provide solid cloud feature sets. We've had many products that are available on Google Cloud and you are able to build whatever you want. There's always a solution for what you need.

The only concern is that there is a number of the offerings which are built on their own proprietary technologies. With some of the offerings in Google Cloud, it's difficult to have a path to migrate to other cloud providers.

I have been Google App Engine for approximately four years.

The solution is easy to deploy. 

I rate Google App Engine an eight out of ten.
