I have been trying out google app engine for some time. Using their code samples of google datastore, I am presently developing an Uber like app to track the public bus movements. I am using com.google.gcloud.datastore presently but is quite restricted compared to com.google.appengine.api.datastore.
What is the difference b/w the two?
When should I use com.google.gcloud.datastore vs com.google.appengine.api.datastore?
Should I switch to appengine.api.datastore?
Thanks.
If you code runs on App Engine, you should use the API built for the App Engine, whether it's a low level API that you mention or Objectify.
If your code runs outside of App Engine instances, you need to use gcloud.

Our project was running in GCP compute engine. For scaling purpose, it is moved to app engine. We had rabbitmq implemented for push messages and chatbots in compute engine. In app engine it is not feasible to implement rabbitmq. So I was going through alternate options. There I found cloud task option. But I have doubts in certain areas even after reading their documentation
In my understanding, we need an app engine instance for cloud tasks. In that case, can I implement it in same project itself as a different service? Will this affect the performance of the existing project?
Is there any better solution than cloud tasks in this case?
You can implement additional services under your app in the App Engine as shown in this diagram.
By default, App Engine scales your app to match the load. Your apps will scale up the number of instances that are running to provide consistent performance, or scale down to minimize idle instances and reduces costs.
You can consider running a RabbitMQ Cluster on Google Kubernetes Engine. You can find more information in the following documentation: rabbitmq.
I want to deploy and app using compute engine as my company does not provide access to app engine yet. Is there a way to deploy the same app using compute engine rather than app engine on google cloud. I have searched multiple forum but unable to find relevant answers.
Any help would be much appreciated.
With python3, I recommend you to write a Flask web application. Your web application will be similar on App Engine and on your compute.
However, you have several things to perform at the infrastructure level. I recommend you to have a look to managed Instances group with auto scaling and health check and Global load balancer.
Note: Because, it's not serverless, you have to pay at least 1 instance even if there isn't traffic on your app
Alternatively, you can have a look to GKE (easier VM management and scaling) and Cloud Run.
Im creating a Node.js website that probably won't have loads of traffic, and was looking into cheap solutions to host the site. Came across Google cloud services offering free usage for their services with limits. A f1-mirco is more than enough for my needs, but I will happily pay for some usage if it goes over by any chance.
I wanted to setup a linux centOS 7 on GCE (which I already did), and run my application and REST API on it. Now here comes the problem.
I tried to use Google's datastore service, but it sprung an app engine instance and without it datastore won't work.
Is datastore entirely relying on app engine to function?? In the docs, it said if you use any of the client API, it requires app engine. What can I do to not use the client api and query data then? Don't want to use the app engine at the moment or datastore is just not for me then?
Thanks for any help!
Some of the underlying infrastructure of Cloud Datastore and App Engine are still tied together for creation, etc. So while creating an Cloud Datastore database also defines an App Engine instance for the project, it doesn't require you to use it. You don't get charged for App Engine either, unless you decide to deploy an App using it.
You should be totally fine use the Google Cloud Node client library on the f1 micro instance.
I am trying Python quickstart project (https://developers.google.com/glass/develop/mirror/quickstart/python) and it is implemented on GAE, however, looking at the code it does not seem that there is much dependency on App Engine itself (code is kind of complicated and I still do not understand it all though).
Is this required to host Mirror-based glassware on App Engine?
Is this required to host Mirror-based glassware on App Engine?
No, it is not required. What you really need is ability to use Google API's and Mirror API is just one of them.
Java quick start, for example does not run on top of GAE.
My application is to use the Google App Engine to provide an embarrassingly parallel computation (and to serve the results to www-browsers). I've been through the Google App Engine "getting started" tutorial but I'm not sure if I need to register my own domain. Do I?
Nope. You can get at your app using the URL <<your-app-id>>.appspot.com. If you later want to wire that up to a separate domain that you own, you can do that, too.
