I am working on a solution that requires many continuously running web jobs. I don't want to package these with any of the Web Apps that are part of our product for reasons of isolation and performance.
I guess some Azure Dev Ops work is involved, but my question is do I have to create Web app with no code, like a Weather Forecast type of project in order to deploy my web jobs.
You are correct. Azure does not have any standalone resource for webjobs. You can create an empty webapp and use that to host your webjobs. Or, you can check out Azure Function app which is quite similar to web jobs as it also utilizes WebJobs SDK but have some additional features as well as constrains. Chris has explained more in details in his answer.

i finished creating my first full stack application using Spring boot, ReactJS and MySQL, I'd now like to deploy this application but I'm unsure on some things and would like clarity.
What is the best approach, do I package my spring boot and react code into a single jar and deploy the entire thing? Do i deploy my backend api and mysql separately and put my frontend on something like netlify? What other approaches are there?
Can i deploy and host the backend and database myself on my VPS and have it available on the internet or do i need to host it on a cloud service or something else. If so, what are the general steps needed to do that. (as well as pricing fees)
I'd like to know some more about devops, what else should I be learning if I want to head down this route?
At the moment I have about $100 credits on Azure and would like to test deploying a full stack app, but I'd also like to know the process without a cloud service.
I am planning to use Firebase database and want to know how it fits in to the following scenario.
lets say I have a browser app, android app / iOS which uses Web Services to get / insert data, web services talks to the Data Base and returns data to the client.
This way I have to write code once in my web services and all the clients use that to retrieve and insert data to the database.
If I want to use Firebase, will I be following the same approach of having webservices between the client's and the Firebase DB.
I have done some sample Firebase examples where it it gets data from database directly without web services and in this approach we have to write our logic on each client (Web browser/ android app/ iOs app).
I have looked into this article
https://firebase.googleblog.com/2013/03/where-does-firebase-fit-in-your-app.html?showComment=1480073224245#c464815735109872173
The Pattern 2 has the server concept but that does not look appropriate in my scenario.
Can I have my web service and Firebase database and get data Synchronization capabilities.
Correct me if I am wrong and please suggest the approach I need to take.
Thank you for your valuable suggestions in advance.
Thanks & regards,

The article you link gives you the most common options for integrating Firebase into your app. Pattern 2 is the easiest way to use the Firebase Database and run your own server-side code:
In this model the Firebase Database sits between the app on the user's device and your back-end code. By using this model, you can still get all the benefits of the realtime synchronization, security rules and scalability, but also have back-end code that runs in a trusted environment.
Of course you can also go for a more traditional three-tier model, where your app server sites between the devices and the database. But in that case the Firebase database won't have direct interaction with your app anymore, so you'll have to take care of the realtime aspects of the synchronization (if you want those) in your own code.
I also recommend reading the Google Cloud documentation on using the Firebase Database and App Engine's Flexible Environments. The architecture described there is the same, but a bit more up-to-date:
I have been working with Azure's web app service using Resource Manager to deploy a Django app. It has been working in fits and starts. I really like the auto-deployment from GitHub but I have been frustrated by the ability to work with the underlying machine. There is a "Console" tool through the Azure portal but it has limited functionality and when there is an internal server error on my app, I can't find the server output log.
Can someone share insight into how to view the server logs?
Azure web apps have a number of logs however, the applications logs provided out of the box only support Asp.Net applications. That being said there is an article about django on web apps and how to store and view its logs here.
What'll you'll have to do, as described in the link, is to setup the django application to store its logs on the azure file system. Another option is to setup the django application to email the devs but the better option is to store the logs on the file system properly.
I am new to developing web services using java. I have an academic project where I need to do dynamic service composition. For that I can't directly create a service-client for a particular service because if I do so then that client will call that particular service only. Client need to search various web services and then out of those services select any one at run time and also call that service at run time.
I was able to develop the web service(JAX-WS) using Eclipse(indigo), I also created the client for that web service and every thing is working fine. Now my problem is that while creating the client I am hard coding the client to call that particular web service only(since I am creating the client using the WSDL file of the service). However I actually need to call any one of the searched service, but for that I need to publish the service some where then discover it and then call it.
I tried publishing the service to juddiv3. But on juddiv3 I could only publish the sample service supplied with the juddiv3. When I try to publish service created by me then it is not getting displayed in the group of published services.
Is there any other UDDI server which I could install on my local machine and then publish and discover the service from that. Also I was not able to figure out how to create a client that will modify itself at run time to call any one service out of various searched services.
Kindly provide the necessary steps and code.
Thanks
You can use jUDDI (http://juddi.apache.org/ ).
juddi is based on UDDI v2.0, v 3.0 .
Here, you can publish as well as discover your web service.
For integration, you have to make some application which integrates with jUDDI.
But I think for your academic project, and for your purpose, jUDDI is best suitable! ( :) )
jUDDI has a boat load of examples in the source code trunk. You may want to check them out. It's difficult to guess what the problem is from the little information you've provided. Consider contacting the jUDDI team for further assistance. http://svn.apache.org/repos/asf/juddi/trunk/juddi-examples/. There's also additional document for working with UDDI in the jUDDI user's guide, which is at the jUDDI web site
You cannot directly publish on jUDDI. You need to create publisher entities in jUDDI server also. You'll find Rename4Sales and Rename4Marketing examples in 'Classes' folder in the standalone server's juddi application. Use these XMLs as your basis and create your own entity. You also need to configure the server's login credentials.
I suggest you follow the tutorials on jUDDI blog.
Simple problem, actually. I am trying to evaluate the possibilities of Google Apps, using Python as development language. It seems practical to create a web application or web site with it, but how about creating web services?
I am not too interested in solutions to create a SOAP or REST service in Python for Google Apps, since a simple Google search should provide plenty of solutions. I am more interested in experiences and ease of use.
But the real question is: When comparing a web service in Google Apps with web services in the Microsoft Azure environment, which would provide the better performance? The best user experience? I don't care for the actual development languages but need a good comparison of pro's and cons of web services in both the Google App Engine and Microsoft Azure.
Somehow, Azure seems better suited for services while Google seems better for sites. A tough choice...
Would be very interesting to see if both could be combined into a single solution. :-)
Btw, choosing which engine to use also means choosing the proper development environment and programming language. While I'm proficient in .NET and Python and many other languages, the choice for the service engine determines my focus for future projects.
When building services in Windows Azure, they'd simply be processes running in your VM (Windows Server 2008 SP2 or R2 SP1). You can host services easily in any of the three role types:
Web Role (essentially Windows Server with IIS running) - just add a WCF endpoint to IIS or self-host from your own process).
Worker role (Windows Server with IIS not running) - self-host from your own process
VM role (your own Windows 2008 Server VM pushed to Windows Azure) - Host with whatever mechanism you install / set up.
Each VM in Windows Azure may expose a total of 5 endpoints. These can be a combination of input (external facing) and internal endpoint, each port supporting tcp, http, or https. You define endpoints in your vm role's properties.
Internal endpoints are only usable by other VMs in your deployment. You can't see them / access them from anywhere else, including other Windows Azure deployments. Input endpoints are accessible by the outside world.
If you want an app running in Google to access your Windows Azure service, simply connect to the endpoint via ip+port. The one thing you'll want to be aware of is bandwidth usage. Because your Google-hosted app will be in one data center and your Windows Azure service in another, you'll pay ingress / egress for data going in and out of your Windows Azure service (and I'm guessing there's an associated bandwidth charge on the Google side, but I'm not sure).
It's actually pretty simple to set up a service. For .NET-based examples, look at the labs in the Windows Azure Platform Training Kit (this also other good examples, such as setting up your first Windows Azure application). For a python service host, you'll need to execute python.exe from your VM role's OnStart() event handler, passing in your script name (and optionally port number to listen on). For a simple example of launching python.exe, look at Steve Marx's blog post here.
EDIT: If you're looking to host multiple services (e.g. multiple ports), you can choose to host them in a single VM role or in separate roles, to optimize for cost (with the known limit of 5 endpoints) or performance (scale each service independently).
