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!

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
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 have an application which ember.js based front end, express.js based REST APIs with postgre as DB. There is also an android application consuming the REST APIs.
I want to deploy this application in cloud. I am very new to this area and not sure what approach to take that will be economical too. Its a startup application and will not have huge traffic in the start. I have been doing RnD on heroku and amazon aws.
Can any one please guide what deployment setup will be reliable and economical for me? Should I use cloude Db?. Any guide line or reference material will be great help.
Sorry If you find this question too generic.
Cheers
You can use AWS EC2 micro instance initially which is low cost.
Once you create the instance, you can install the tools required for you in instance.
What you need is create a AWS account and create the instance. In order to create a instance you can do it from console. Later you can access the instance using secrete key and access key. If you are a new user to AWS. Yo can get the usage free for one year.
As part of AWS’s Free Usage Tier, new AWS customers can get started with Amazon EC2 for free.
More details about free usage and pricing
As your application grows you can use Opscode Chef or puppet for configuration management.
How to change the url of windows azure application which is in cloud?
modify the url from xxx.cloudapp.net to yyy.cloudapp.net
thanks for your helps
You can't do that! The only way is to create new cloud service and deploy your package there.
Please note that creating cloud service is nothing else but reserving the DNS name (XXX.cloudapp.net). You are not being charged for creating cloud services. You are only charged for when you deploy something on those cloud services. So you can create as many as you wish (well, I think there is some soft limit on the number of cloud services you can create, so delete the ones you are not planning to use).
When you go for production I highly suggest you to use your own custom domain (i.e. www.mycomany.com). For this, please follow the instructions here.
I have some hardware devices that send some data that need to be stored on the cloud server and also I need to do some real time processing on them.
The data they send need to be preserved for months in some custom binary files. These files related to each device can grow in size up to 10GB over time.
There will client programs (mobile / web) that will be looking at the processed data at real time.
My prefered choice of language is C/C++/C#, since there is time sensitive number crunching involved.
Goal is write scalable application that can have thousands of such devices monitored on the cloud.
Do I have to upfront write the code for running on the cloud ( undestand Azure / amazon EC2) ? Can I write multi threaded desktop application and later migrate to cloud ?
I have used Message passing interface (MPI) in the past for clusters. Can I still use MPI ?
If I use microsoft azure API can I still host my software on Amazon cloud ?
For mobile devices to talk to the server, I understand that I need to have a webservice running. how can I convert a desktop program writeen in C++ / C# to act as a web service talking to client?
Are there any 3rd part frame works or tools taht can help me with my work ?
With most cloud compute services you can deploy an off-the-shelf server and install your own software on it. So, yes, you can write and test you application locally then migrate to the cloud once you get all the bugs worked out. Here are the available EC2 server configurations.
I have not tried MPI but you should be able to run just about anything you want on the servers in the cloud. However, Amazon does offer the Simple Queue Service which provides message passing in the cloud. Your software does not need to run in the cloud to use this service.
I have not used Azure. I doubt there are any restrictions regarding which external servers you use for storage and/or compute. However, keeping your cloud storage and compute resources within a single provider will reduce costs, improve performance and provide you with a unified management interface and billing system.
Web servers are fairly simple things. See this post. That took me about 10 seconds to find.
There is plenty of third party software out there. Figure out what you need in more detail and ask more specific questions
