You would need to follow the <a href="https://cloud.google.com/datastore/docs/activate#accessing_the_short_product_name_api_from_another_platform" rel="nofollow noreferrer">Accessing the Cloud Datastore API from another platform</a> procedure:

<blockquote>
 This section shows how to activate and access the Cloud Datastore API
 from an external application running on a platform outside of Google
 Cloud.
 
 <ol>
 <li>Enable the Cloud Datastore API for the project. You can enable the API for an existing project, or create a new project and then enable
 the API.
 <a href="https://console.cloud.google.com/flows/enableapi?apiid=datastore.googleapis.com" rel="nofollow noreferrer">Enable the Cloud Datastore API</a></li>
 <li>To use the Cloud Datastore API, your Cloud project requires an active App Engine application. Open the App Engine dashboard and
 confirm your Cloud project has an active App Engine app.
 <a href="https://console.cloud.google.com/appengine" rel="nofollow noreferrer">Open the App Engine dashboard</a>
 
 Create an App Engine app if needed. The app must not be disabled.</li>
 <li>Go to the <a href="https://console.cloud.google.com/apis/credentials/serviceaccountkey" rel="nofollow noreferrer">Create service account key</a> page.</li>
 <li>Click the drop-down box below Service account, then click New service account.</li>
 <li>Enter a name for the service account in Name.</li>
 <li>Use the default Service account ID or generate a different one.</li>
 <li>Select JSON in Key type.</li>
 <li>Click Create.</li>
 <li>Upon successful creation, your browser will download the private key. The Cloud Platform Console provides a prompt that displays the
 private key file name. Note the file name so you can locate it, then
 click Close to dismiss the prompt.</li>
 <li>Your Service Account is the Email address displayed under the Service Account section.</li>
 <li>Your Private Key is the file you just downloaded.</li>
 </ol>
 
 At this point all services and authorizations are configured for your
 project and you can start writing code or exploring the API.
</blockquote>

You don't actually need to write code for the GAE app and deploy it, see <a href="https://stackoverflow.com/questions/40401696/is-an-app-engine-instance-required-for-accessing-datastore">Is an App Engine instance required for accessing Datastore?</a>

As for being more economical or not (I presume compared to running the app on GAE) - it depends a lot on the app's usage/scale, what the app does and how it does it.

Have a look at Cloud Endpoints

I want to use datastore of google in my web app but do not want to host it in google app engine, I want to host it some other machine. So how i can use datastore in such web app ? 
will it be more economical ?

How do I use Google datastore for my web app which is NOT hosted in google app engine?

我想在我的web应用程序中使用google的数据存储，但不想将其托管在google应用程序引擎中，我想将其托管在其他计算机上。那么如何在这样的web应用程序中使用数据存储呢？这样会更经济吗？
