I have my applications deployed in IBM cloud. Moreover, I am using Send Grid services in my application. So I want to enable domain authentication in Send Grid to send mails efficiently.
But I am not able to figure out the DNS host for IBM cloud. The following below DNS options are provided by Send Grid:
123Reg
Alibaba Cloud
Amazon Route 53
Cloudfare
ClouDNS
CSC Corporate Domains
GoDaddy
Google Cloud
and many more. I found in Google that IBM domain is www.softlayer.net but in my IBM console I am not able to configure the DNS. Any help?

I am getting to the point of my project where I am ready to deploy it online with my custom domain via Azure once I make the upgrade from my Free Subscription.
So a little context, I have 1 web app service and 4 api services and each one is hosted in a separate app service such as:
www.sitename.azurewebsites.net
www.sitename-api1.azurewebsites.net
www.sitename-api2.azurewebsites.net
www.sitename-api3.azurewebsites.net
www.sitename-api4.azurewebsites.net
And the above web app communicates to all 4 api's and some api's may or may not talk to another. (Would have loved an application gateway so hopefully I'll be changing this architecture later down the road).
So as I get ready to associate my domain to the services, the web container seems pretty straight forward to me as it just becomes www.sitename.com, but I am a little confused about the api services. The way I am thinking about this is that each api service will be in it's own subdomain, such as:
www.api1.sitename.net
www.api2.sitename.net
www.api3.sitename.net
www.api4.sitename.net
where I believe I can register my SSL and domain to each app service somehow, but this leaves me with a few questions.
Do I host each api in a subdomain using the same domain as the web
app, or is there a different way preferred like where I host them
all on the same domain with different exposed ports per API and web
listening 80/443, or maybe just use the IP address of the api app
service and allow www.sitename.com as the origin for CORS?
I am assuming that since I am associating my SSL cert to the web
service, I will need to do the following on the api services?
Would it be better (and still affordable) if I just had a VNET
associated to the app services and the domain only registered with
the web app?
Any insight into this would be greatly appreciated on how I can establish communication between my app services with my custom domain and SSL as I am fairly new to this part of the stack, but excited about learning!
As I known, on Azure cloud, there are two services can help to manage your APIs deployed on multiple app service containers: API Management and Application Gateway.
The Premium tier of API Management has the feature for multiple custom domain names, please see the offical document Feature-based comparison of the Azure API Management tiers as the figure below.
You can refer to the quick start tutorial of Create a new Azure API Management service instance and other related documents to kown how to.
"Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications." said in the introduce What is Azure Application Gateway?. And as the figure of its architecture below, "With Application Gateway, you can make routing decisions based on additional attributes of an HTTP request, such as URI path or host headers. For example, you can route traffic based on the incoming URL. So if /images is in the incoming URL, you can route traffic to a specific set of servers (known as a pool) configured for images. If /video is in the URL, that traffic is routed to another pool that's optimized for videos."
I recommended to use Azure Application Gateway which be a good choice to manage multiple app services and expose the unified urls of APIs.
I have multiple web apps on Azure that I want to put behind an Application Gateway in order to use a single domain name with path routing.
However, my web apps needs to connect to a db outside of Azure. So I wonder what will the IP of the requests from these web apps to the db would be? I hope it will be the gateway public IP so I only have to authorize one IP at my db provider but I don't find any docs to confirm it (or not).
So I wonder what will the IP of the requests from these web apps to
the db would be?
If you want your web apps to connect a database outside Azure, you may need App service Environment. Because the Web Apps need VNet to connect other resources. Also, due to the date base is outside Azure , you need to create VPN gateway to connect it. This connection is between the Web App and the database, not Application Gateway and Database.
So, the IP of requests from those Web Apps is not the IP of Application Gateway, It depends on the VNet in App Service Environment.
This picture explains how this environment works:
I hope it will be the gateway public IP so I only have to authorize
one IP at my db provider but I don't find any docs to confirm it (or
not).
Also, if you still want to use one IP to connect other resources, you can also add Internal Loadbalancer to achieve that.
You can see more details about Integrating your ILB ASE with an Application Gateway to help your deploy resources.
Please let me know if this answer helps.
I would suggest using the Azure Web App's Hybrid connection. This provides a TCP tunnel in a secured fashion between your azure web app and your SQL db. There is a service bus in between and you have to install the relay agent in your network that does the outgoing communication to this service bus.

The app gateway's public IP address can't be leveraged nor is it necessary to manage connections between Azure Web Apps and databases outside of Azure. The web apps have their own IP addresses.
On another note, my blog post may be useful to understand how the architecture and configuration between app gateway and azure web app.
I am currently working on a java back end server that I am deploying to bluemix. It is a standard web app, built out with maven and hits a mounted data base. Standard stuff.
The question becomes is that two of the end points that I am using are hitting services that exist on networks that have their own firewall.
Now if I deploy the application to a server that is punched through the firewalls, all is well. However on bluemix where I am not punched through these firewalls, I often get 401 errors.
Does anyone know of a way to pass these credentials when doing a post or get so that I can authenticate through the firewall, and then authenticate through the service?
Thank you all.
You can use one of the following Bluemix services to connect your application running on Bluemix to your on-premise application/database behind the firewall:
Secure Gateway
Cloud Integration
With Secure Gateway you can create a secure tunnel between Bluemix application and your on-premise application. The official documentation is available here, but there is also an excellent article in the link below to start with this service:
https://developer.ibm.com/bluemix/2015/03/27/bluemix-secure-gateway-yes-can-get/
Alternatively the Cloud Integration service documentation is available here.
I have a Web Api 2 project that sends Push Notification to an android app via Google Cloud Services. Running locally, I can get my machine's ip address and set this in my included IP's for my service api in Google API console, which works fine. However, I now deployed to azure and this is no longer working. I did an ip looking on my site name, so for example mySite.azurewebsites.net, where the site is hosted, but this does not seem to work.
Is there a way I can get the ip address of the service that is hosting my asp web api project in azure?
Have a look at the following tutorial. This might help you out in finding out the the IP address of the web api project you have hosted on Azure.
I'm new to Azure and have set up an Asure web site which will connect to a SOLR instance on an Azure VM. The web site cannot communicate with SOLR (port 8080) unless I create an endpoint. In order to create an endpoint I need to provide an internal and external port, however I do not want to allow external/remote access to SOLR, other than from the web site itself. Can anyone tell me how I should allow the web site to communicate with my VM, without making the VM publicly accessible?
Thank you,
JP
As #hhaggan stated, you cannot create a virtual network connection, or secure an endpoint, from Web Sites to a Virtual Machine. One option to consider is the use of SSL+certificate to secure the endpoint.
If you instead deploy your web application to a web role (in a cloud service) or a virtual machine, you can then take advantage of a brand new feature called Endpoint ACL. In essence, you can whitelist / blacklist a set of IP address ranges that may access your SOLR external endpoint. You can read about ACL'd endpoints, and how to configure them, here.
Now: You might be asking yourself why this doesn't work with Web Sites. That's because Web Sites runs on a server farm, and sites don't get unique IP addresses (unlike Cloud Services).
if you are talking about Windows Azure Websites, I am not sure if this can be done but if you are talking about Web roles in Windows Azure Cloud service, here is something that I hope it can be beneficial.

you might also would like to have a look on this http://www.windowsazure.com/en-us/services/virtual-network/ I don't think you will need it but I am just sharing it with you, it is for WIndows Azure Virtual Network.
let me know if this solved your problems or if you need anything else.
