In Google Chrome, I can sync my browser history across multiple devices. Presumably then there is a Google web service which is used to share this browser history; is this a publicly accessible service? If so, how would I query it?

I started a web server on EC2 following the basic instruction on AWS website. The web page (index.html) since yesterday is not accessible through the browser (chrome & edge) but is accessible from my mobile. I have not made any changes to my desktop settings which should affect this.
Any pointers on how to investigate this would be great?
Check your security groups and access control lists to confirm that you have not accidently allowed traffic to the page only from certain ip address/addresses.
We currently have a large array of customers (1000 different on-premises installations).
We use a single server to host our sites which communicates with on-premises WebAPI's.
Currently we limit the traffic to the local servers in the router to allow only our server to access the local API's.
However we are considering moving alot of these webservices/sites to Azure which in turn means limiting on the IP's addresses becomes not feasible.
What approach would you recommend to allow the Azure servers to access the on-premises servers?
Best case scenario would of course be that no ports needed to be open in the routers (limit maintenance) however this seems very hard to accomplish if we still would like the ease of development that WebAPI gives us.
Otherwise we have thought about opening for public access to the API's but securing with https and authentication.
Does anyone have any alternative solutions?
Note: The on-premises WebAPI services are hosted with selfhost inside a Windows Service.
You could try using 'Azure Hybrid Connections' to access your on-premises Web API.
You could host your websites as 'Web Apps' in Azure App service and access your Web API.
You do not need to open any firewall ports or change your network perimeter configuration to allow any inbound connectivity into your network
I'm very fresh and beginner in the web services world, I'm trying to learn how to deploy and consume services.
My question: Using any technology (such as Java), when I want to invoke some web service that is deployed in a remote server, do i need to install and configure a localhost server in order to access the web service? or I can access it without install server
Note: I'm asking about consuming a web service not developing a one
Thanks in advance
No. Just as your web browser doesn't require a web server to access other web servers, your code doesn't require a web server to access other web servers.
I have a web app and a web service (which will be uploaded to Azure as an web app). How can i make my web service private (not accessible to the public, only accessible by the web app). Apparently you're able to do it with an App Service Environment but there isn't much documentation on it.
Is it possible?
You can follow this article to set it up: https://azure.microsoft.com/en-us/documentation/articles/app-service-web-how-to-create-an-app-service-environment/
The main difference between App Service and App Service Environment (ASE) is that App Services run on a pre-built, shared tenant hyper scaled web farm, but ASEs are purpose built (on demand) web farms provisioned directly in your subscription that must be attached to a VNET. Because you can attach your ASE to a VNET, you can then apply Network Security Groups (NSG) to the VNET to prevent/allow traffic to flow to the ASE.
Here is the page describing how to add the layered security to your ASE once you've built it:
Layered Security Architecture with App Service Environments
So with ASE you get the deployment/monitoring/management features of App Services, but with the network layer control of a VM.
How can i make my web service private (not accessible to the public, only accessible by the web app).
Network Security Groups could be used to control network traffic rules at the networking level, we could apply Network security group to the subnet to let Network security group act as a firewall in the cloud. #Russell Young has shared us a good article about setting up Network security group, you could read it. And you could check this blog that explained securing network access using Network Security Groups.
Besides, it is easy to implement a custom authentication to prevent unauthenticated client from accessing to your Web service at application layer. For example, we could use SOAP headers for authentication. Web service client credentials would be passed within the SOAP header of the SOAP message when the client want to access to Web service, and then Web service will validate SOAP header, if it contains the authentication credentials, the client will be authorized to access to the Web service.
You could check Implement Custom Authentication Using SOAP Headers.
Does anyone know whether it is possible to route network traffic from an azure mobile service through a VPN to an on premise web service? None of the documentation I have read precludes that, but neither does it say we can. So far we have had no success though we can access the web service using a web browser VM in the same subscription. We can't run any new software at the site hosting the web service, so it would seem like Service Bus Relay cant be used and the web service can't have a publicly exposed ip address.
have a look at Mobile Services with an Azure Hybrid Connection. The walkthrough talks about exposing an on-premise database, but i think you can use the same steps to expose a different TCP port for your on-premise web service
