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!
Is it possible to add application insights for web api that's hosted on the on-premise version of service fabric?
So far I have tried to add the application insights to my project and wondering where to send for monitoring. It was easy when app is also on cloud.
I believe there is no on-premise application insights service, so even if the web api is hosted on-premise over service fabric; one must use cloud version application insights service, is that correct? In that case can anyone let me know how to setup?
App Insights is only hosted in Azure. If you're looking for an on-premise solution, you're best off looking at using something like the ELK stack (Elastic Search, Logstash and Kabana).
Nonetheless, even though your cluster is hosted on-premise, using Asure App Insights is still very much a valid scenario (assuming your IT organisation is fine with it).
Assuming you're fine with Application Insights, I strongly recommend you have a look at App Insights Service Fabric. It works great for:
Sending error and exception info
Populating the application map with all your services and their dependencies (including database)
Reporting on app performance metrics, as well as,
Tracing service call dependencies end-to-end,
Integrating with native as well as non-native SF applications
One thing however that the above won't solve is providing overall cluster health information - e.g. when/how often nodes go up/down, how much CPU/Memory and disk IO is consumed on individual nodes. For this you could try MS EventFlow or a custom windows service
There is no "on premise" application insights, but as long as your on premise service has access to send outbound data, you can use application insights on your site. You won't be able to use some features, like webtests, because application insights wont be able to make calls into your site.
Setup is the same as always, create an application insights resource in azure, and either configure it in visual studio, or manually set the instrumentation key in your applicationinsights.config (or via code) in your app.
If you need to configure outbound firewall rules or anything to let AI send data, that information is all here: https://learn.microsoft.com/en-us/azure/application-insights/app-insights-ip-addresses
I'm using Parse.com SDK services for my Android app.
I've seen that Parse had released their Android SDK as an open source project on Github on this address.
My app is almost finished, and when I'm uploading it to the Play Store, I don't want to be controlled by Parse.com (I mean that I don't want to be blocked someday, or I don't know that), so I want to move my whole database to my own server that hosted on a secure company.
I've checked the open source project on Github and realized that all I need to use it on my own server is to generate an Application ID and a client key.
So I want to ask if someone knows how to generate an Application ID and a client key of Parse to use it on my own server, or that you maybe knows another way of moving it to my server? And one more question: Today I'm using also Facebook SDK with my app. If I will move my database to my own server, will I still be able to use Facebook SDK on my app?
Thanks!
I have write an article about how to migrate parse to a custom server.

There's a massive difference between Parse open-sourcing their SDKs compared to revealing their entire backend architecture and its configuration.
The open-sourced SDKs are essentially wrappers for Parse's REST API along with some convenience functions and logic for natively interpreting the JSON data Parse is transmitting.
At a high level, Parse uses MongoDB for its core database and is entirely hosted using AWS (Amazon Web Services). The entire architecture is highly complex and is not something you could just drag and drop onto your own software stack or hardware backend.
To help give you a better idea of how Parse achieves all of their services, here's an interesting presentation their Dev Ops team gave at an AWS convention. Suffice it to say, hosting the backend services for over 180,000 apps requires a complex infrastructure and that is the "secret sauce" so to speak for Parse and is why Facebook purchased them for over $85 million two years ago.
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.
I am working on creating a Windows 8 application. UI is using HTML5. Using WinJs I am calling a WCF service that returns a datatable used to build out the UI. All that is good.
I would also like to create a Window Service that gets packaged up with the application, so when someone download/installs it gets unpackaged and the windows service is started/executed. Is this type of configuration possible?
The WCF service today is a web service, but I would like to make it a windows service. The idea is to make everything self contained. This would allow me to make it available in the Microsoft Online store - if I wanted to go that route.
Windows 8 Applications don't support installing services. The best you can do is install a service separately.
Your WCF service should be decoupled from your app and most probably running on a different machine! I am pretty sure that the they are not going to allow you to install or run services in context of a Windows Store App.
Installing a windows service is not an ideal approach for any Windows 8 application. I understand that you want to make everythig self contained but, why as a WCF local service then? Why don't you consider having it has a data access layer in your app itself? Just a thought.
REGARDING CLIENT SIDE
Web services are separate projects and separate deployment models. You can have one Visual Studio project for the Windows 8 client app and one project for the Web Services side.
Windows 8 apps have several options for saving persistent data, such as endpoints for consuming web services.
There are several consideration when storing Windows 8 application data, such as the location of web services to be consumed.
Windows 8 Application data also includes session state, user preferences, and other settings. It is created, read, updated, and deleted when the app is running.
There are 3 types of dimensions to consider. The system manages these data stores for your app:
(1) local: Persistent data that exists only on the current device
(2) roaming: Data that exists on all devices on which the user has installed the app
(3) temporary: Data that could be removed by the system any time the app isn't running
As a developer, you concern yourself with a couple of objects to persist application data:
The first container object is ApplicationDataContainer. The other is ApplicationData. You can use these objects to store your local, roaming, or temporary data.
REGARDING SERVER SIDE
Your Windows 8 Client app will consume http-based web services.
Most developers deploy web services to the cloud to be consumed by iOS, Android, Windows, and other server side services.
Windows Azure is a cloud offering that makes exposing services to clients very simple.
You can leverage either cloud services for robust solutions or the lighter weight Azure Web Sites.
You can typically choose either of these two project types to create web services:
(1) Windows Communication Foundation WCF; or
(2) ASP.NET Web API, which is included with MVC version 4.
WCF has been around longer and has historically been the primary choice for developers when it comes to exposing services.
Microsoft's more modern concepts about web services relate to the ASP.NET Web API, which truly embracing HTTP concepts (URIs and verbs). Also, the ASP.NET Web API can be used to create services that leverage request/response headers, hypermedia, etc.
