I was looking at Azure SDK for ruby and after comparing the API available there with the list of Azure's services, I noticed that the SDK does not have API for achieving many of the tasks related to various services. Are the API mentioned on SDK's github homepage the only API available ?
Eg: It has API to create a virtual machine, but no API to add DNS server.
The SDK has API to create Virtual network which can take params or XML file.
I also want to know whether we can configure other services using XML files and if yes, where can I find the XML data structure to configure those services.
The azure documentation is huge and I am unable to find proper reference for the XML data structure and list of services which can be configured using Ruby SDK.
FYI : I am on Ubuntu machine and cannot use Azure's other tools which are specific to only Windows.
I wrote an Azure API client (that despite my best efforts, has remained closed source) in ruby that my company uses, and I can relate to how much of a beast their API can be. You will find the best resources here, which will document all of the XML that can be configured. It might also be relevant to note that the official cross platform SDK is actually their Node.js client, which is available at github, which will definitely work on Ubuntu, better than the Ruby SDK.
Following is the list of services configurable by the azure-sdk-for-ruby
Base Management Service (creating affinity group, listing locations)
Cloud Service
Storage Management Service (Blob, Queue, Table)
Service Bus Service (Queue, Topic) - Could not make it work.
SQL Database Management Service
Virtual Machine Management Service
Virtual Image & Disk Management Service
Virtual Network Management Service
I have created a quick reference of available methods and short description of various Azure entities.

This is what I would like to build. A hosted web/api project built on APB where tenants can use the web application to define "Scan Definitions" that run inside their network. A scan definition would just contain a target IP Address to be scanned with WMI. They would download and install a windows service that would run periodically in their network. The service would communicate with the APB web API to retrieve scan definitions, then run the scan and upload the resulting scan data into the APB web API. Then the users would be able to view that scan data within the web app.
My question is with the CORS access in place, how can I make it so that the windows service is allowed to talk with the API. Also what is the best way to authenticate the service with api such that the service would know which tenant it should be using so that it pulls down the correct scan definitions and uploads the data to the correct tenant as well.
Thanks in advance for any help or guidance.
I was able to get a service up and running by following the abp sample found here: https://github.com/aspnetboilerplate/aspnetboilerplate-samples/tree/master/ConsoleRemoteWebApiCall/CallApiFromConsole
I still have things to work through, but it's gotten me to a spot where I can access the api from a console application
Our customer using Alibaba cloud to deploy their application. They rented dozens of VMs/instances. We are asked to using API to get instance configuration (i.e. number of core, memory, network bandwidth, SSD, disk type, zone and etc) by program. We have found Ali open APIs in github./1/
Could someone point out which exact API could we call to get instance configuration?

You can use the DescribeInstanceAttribute API. I feel it's very helpful to use the APIExplorer to debug APIs. You don't need to install SDKs, CLIs, write any code, and configure access keys etc. Just login your Alibaba Cloud account, fill in some inputs, and click the Send Request. Everything is there!
I am currently working heavily in Azure. I am actually quite fond of ARM (Azure Resource Manager) right now and would love to keep using it. Right now in the old portal, We have a lot of resources tied up as Cloud Services. Now, I know cloud services are available in the new portal, but it seems that Microsoft is moving away from the classic cloud service model. Can someone explain if this is true? If so, what will the new model look like? I already use resources groups to manage Websites (WebApps), so I assume this is where the azure future lies. Will we see the "deprecation" of cloud services on down the line?
I am trying to understand if I need to begin re-structuring my Azure Infrastructure.
Any insight, explanation, or documentation is greatly appreciated.
So there are two things here - Cloud Services and managemenet of Cloud Services.
When you manage Cloud Services in current portal the underlying mechanism used is Azure Service Management (ASM) where as it is Azure Resource Manager (ARM) in the preview portal. To me, ARM is the new way of managing your Cloud resources in Azure (including Cloud Services).
I don't work for Microsoft so I would not know if Cloud Services themselves will be deprecated down the road or not but one thing I think will happen is that ASM will be deprecated in favor of ARM. At some point of time, the only option you will be left with managing your cloud resources will be through Azure Resource Manager. One example that makes me believe this thing is the presence of Classic resource providers (e.g. Classic Storage Resource Provider which enables you to manage storage accounts created in current portal via ASM in the preview portal which works exclusively on ARM).
Personally I can't see a place for cloud services in the new ARM world of Azure. I have always found them a convoluted concept that simply added complexity to a deployment.
In the ARM view of deployments servers are collected together in a VNet, and each server is attached to a Nic which in turn can be connected to the internet. A security group then takes care of ingress / egress rules.
This is a much cleaner deployment method, as it puts connectivity configuration at the server layer instead of mapping them all through a higher layer of abstraction.
I don't see the place of cloud services in ARM, however after a quick search it seems that there is a plan to implement it
Still no direction from the Azure Advisers group other than officially they will not drop support for Cloud Services. I think they are nearing giving us some kind of direction but I can't say anymore than that.
I asked a question about the future of Cloud Services on the recent Azure Compute AMA.
You can read the answers directly on Reddit for all details, below are a few interesting quotes (emphasis mine).
On ARM Integration for Cloud Services:
We are looking at ways to make the transition to ARM easier for Cloud Service customers- one of those options includes CS integration in ARM. This investigation is in the very early stages though, so if you are looking for a solution soon, check out VMSS/ACS/SF/Web Apps (meagan-msft)
And:
I think it's safe to say that if we make any significant investment in CS in the near future, it would be ARM integration, and as Meagan suggests, that's still in planning. Beyond that, there are no major feature improvements on the horizon. We believe the platform is pretty mature at this point. (seanmichaelmckenna)
So it doesn't look like any major innovations will hit Cloud Services soon, however:
Cloud Services are not going anywhere. In fact, many Microsoft services run on Cloud Services, so we heavily rely on them as well. They are fully supported, so feel free to continue to use them.
(meagan-msft)
For those who want to switch to a different Compute service, these recommendations were made:
However, if you would like to check out other services that are integrated with ARM today, we recommend checking out the following:
Web Apps for customers who want a fully managed platform and are building traditional web applications
Service Fabric for customers who want an opinionated application platform and managed infrastructure, but still need some control over the IAAS layer
VM Scale Sets for customers who need IaaS-level control with easy scaling, autoscale and load balancer integration
Azure Container service was also listed as a potential alternative.
Some things to consider (my understanding):
Service Fabric currently (2017) requires at least 5 VM instances, except for dev/test purposes. So probably only an option for larger services
VM Scale Sets is an IaaS offering, i.e. you have to manage OS updates etc. yourself. However, support for automatic OS updates is being worked on.
I heard that apps don’t port directly and they have to be specifically written to work with Azure. I’m new to Azure and did some reading but I don’t see anything from their site or documentation that suggests that you must specifically code for Azure, so is it true?
If this question is better suited for another StackExchange site please let me know.
You should take a look at the Windows Azure Platform Training Kit to see some introductory project labs.
While you theoretically can just "drop in" some apps into a Windows Azure VM, it hardly makes sense to do so. Some apps can be migrated with only minor changes, such as an asp.net website - session state is easily handled by AppFabric Cache, and the Web Role VM is Windows Server 2008 with Full IIS. However, you'd still need to integrate with Windows Azure Diagnostics, to be able to have external visibility to the health of your app.
Further, with the example above, there are more optimal things you can do, such as moving static content to blob storage, and taking load off your VMs. This requires you to upload this content, and then change your IMG and other tag URLs to point to a slightly-different URL.
Just remember that you're moving to Windows Azure to take advantage of its platform and related services, not just to be a rack to host a server. To take advantages of these services, you're going to have to target them specifically, such as:
Access control services
Caching
Connectivity (vpn, service bus)
Diagnostics
Database (SQL Azure)
Synchronization services
Traffic management across data centers
This is somewhat true. Your apps will typically run as-is. You just need to add an azure project to the solution, and add your MVC apps as roles to the Azure Project.
I found O'Reilly's "Programming Windows Azure" to be a good conceptual introduction to Azure.
I am trying to understand exactly an AppFabric in Windows Azure, What is the difference with Worker Role and Web Role and How to create a project of AppFaric in Visual Studio 2010, i mean which kind of project ?
Thx.
Adding a bit to vtortola's answer:
There are three core areas of the Windows Azure platform:
Windows Azure (which provides virtual machines and massively-scalable storage through Blobs, Tables, and Queues
SQL Azure (which is a large subset of SQL Server), offering a full relational database up to 50GB
Windows Azure AppFabric (a set of services that you can opt into, currently comprising access control, connectivity, and caching)
When you construct your Windows Azure application, you can really pick and choose what pieces of the platform you're interested in. For instance, Windows Azure provides Web and Worker roles (both essentially identical virtual machines running Windows Server 2008 or R2, but Web roles have IIS enabled). If you need a relational database, you can very easily set up a database. And, then there's AppFabric:
If you need to connect to a set of web services on premises, for instance, you can use the AppFabric Service Bus (a secure way to connect without having to open up a firewall)
If you need to actually connect to an entire computer on-premise, use Azure Connect (a software VPN).
If you want to cache data (such as asp.net session state) between instances of your virtual machines, enable and use the AppFabric Cache (currently a Community Technology Preview, so no pricing yet).
If you need to add access control to your application, use AppFabric's Access Control Service, which essentially lets you outsource your identity management.
There are quite detailed examples in the Platform Training Kit that vtortola referenced. Additionally, there's a complete Identity Management training kit.
Azure AppFabric is a suite of middleware services and technologies to help you develop and manage services/applications that use Windows Azure. Middleware is typically defined as software that helps connect other pieces of software, and this definition is pretty accurate for the services appFabric provides.
You don't create an App Fabric per say. AppFabric services are used by your other applications as needed, so setup is typically configuring certain items in the Azure Portal, then implementing libraries of config entires in your web/worker roles that leverage the resources.
Essentially AppFabric provides certain resources that you need when composing complex applications as services, vs. you having to implement and maintain these resources yourself.
The basic offerings are:
Service Bus: A message relay that can be consumed by other .NET technologies (and others). SB helps you connect different cloud services as well as "hybrid" services. The hybrid is a big deal, as SB helps you easily connect on-premise web services with services you run in the cloud, w/o having to mess around with VPN, protocols, server setups, certificates, etc etc.
Access Control: An authentication and authorization service, helping you manage user-level access without having to extend/implement Active Directory, LDAP, and custom user authentication modules throughout Azure.
Caching: an in-memory distributed caching layer for your applications. This is typical to memcached or the Windows Server version of AppFabric
Integration: a PaaS service of EDI/transport technology like BizTalk server
Composite App: allows the composition of complex applications using a compistion language versus just putting a bunch of code together. You basically define your application using a designer like you would a EF.Net data model or a Windows Workflow
So basically AppFabric provides you with a lot of services that you likely need, but the typical cloud developer may not want to "mess with" at least at first. This way you have these great building blocks to help you focus on your core logic/needs during development cycles while not limiting what your application can ultimately do. This "focus" is one of the core benefits to cloud computing, especially Platform as a Service, and is one area where Azure really shines compared to other offerings.
Some of these technologies are still in beta. The AppFabric site makes this very clear, but its important to be aware of.
Great place to start is the Azure AppFabric site itself, which breaks a lot of this down, gives you great examples of how to use, and some sample code for you to get your feet wet.
http://www.microsoft.com/windowsazure/AppFabric/Overview/default.aspx#top
Basically:
WebRole : similar to a web
application.
WorkerRole: similar to a Windows
service.
AppFabric: Group of services that
allow you interconnect applications inside and outside Azure.
Download and read/do the Azure training kit, it will solve those questions and tell you how to create that project in Visual Studio step-by-step.
