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.

We are looking to use Google App Engine for one of our low latency service. We are required to provide low latency service across the globe. Since Google App Engine is a regional service and there is no straight forward way to deploy it multi-regional. So, looking at Google Load Balancer to route at DNS level, but that also does not seems to be possible as load balancer not supporting App Engine as a backend service. Is there any other way to achieve GeoDNS routing in GCP for App Engine service.
There is not an direct way to achieve GeoDNS routing since App Engine is a regional service, as you said.
Read this feature request to have further insight on this. In the second comment they state the two possible workarounds, useful for both standard and flexible environments:
The workaround is how you mentioned, using a single project with a load balancer to route requests to Compute Engine instances in
different regions. Then have each Compute Engine instance act as
proxies to an App Engine project in each of the different regions
(where you would copy your code to each App Engine project).
It may be easier in the meantime to use Google Kubernetes Engine instead of App Engine for multi-regional application serving.
You could star the FR to support it.
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.
Google CloudSQL gives the option to allow it to follow an App Engine app for better performance.
How can I do the same with a Google Compute Engine instance? Otherwise what is the best Google data center to house my instance for best performance with a US based App Engine app?
Depending on what you're trying to achieve the way to go might be an app with two modules, one of which is a managed vm.
If you need a persistent disk in your managed vm you can mount cloud storage with fuse in your managed vm.
I am very newly in google app engine.. There are three Questoins on google app engine and in google app engine i want to choose JAVA language.
Does google app engine provide private cloude ?
I want to deploy my application with my own server( E.x.glassfish or JBoss) on google app engine ?
I want to use my own database instead of cloud SQL in google app engine?
Is it possible or not?
With Google Cloud Appengine - no, it's impossible.
With Google Cloud Instances or Google Cloud Containers - all of this is possible.
Appengine is just one piece of Google Cloud, designed for very specific job, with infrastructure managed by Google. You can only write some code (with lot of restrictions too) that runs inside it. You can read some details about code restritions there: https://cloud.google.com/appengine/docs/java/#Java_The_sandbox
What you're looking for is Google Cloud Instances, that are more standard virtual machines, where you can run anything you want. See https://cloud.google.com/compute/
There is still tools for Load Balancing, Health Check, Centralized Logging for Cloud Instances, and other stuff similar to features provided by Appengine.
I am pretty new to this whole idea of cloud and started of with Google app engine. I was able to create the basic 'hello world' program.
When i tried to understand the difference between a cloud and a server I learned that Cloud is where you have an access to virtual instance created exclusively for you and you are free to choose and install software of your choice.
But I don't see such an option with Google-cloud/app-engine. What if I have a tom-cat based application server which I would like to deploy on a cloud? Will Google app engine be of any help or should I try other cloud service providers such as Amazon EC2, hp cloud etc?

The cloud type that you are referring to is called Infrastructure as a Service cloud.
OTOH, Google App Engine is Platform as a Service cloud.
The difference is that IaaS are a bunch of virtual machines that you need to setup yourself (OS + app stack), while PaaS typically comes with it's own API, where you write your app against the API and the rest (sw stack + scalability) is taken care of.
AppEngine comes with it's own servlet container (Tomcat is also a servlet container), so from this standpoint you could use your code on AppEngine. But the problem lies elsewhere: AppEngine imposes a set of limitation on the apps:
app must use GAE provided databases.
app can not write to filesystem
app can not have listening sockets
requests must finish in 60 seconds (e.g. no Comet or WebSockets -> no push)
You might want to review the FAQ.
To add to Peter's excellent answer, note that Google also has an IaaS service called Google Compute Engine.
Regarding other cloud query-
Before you start with cloud you might once try other options. Currently deploying application in almost all services are very easy.
few of them are-
Jelastic , Heroku , rackspace , nimbus , openshift etc.
Difference between cloud and server is very well explained already.
Since you mentioned about tomcat based application , I have worked with Jelastic for the same and found very easy to implement.
