This is regarding Microsoft's Azure DevOps(Formerly VSTS). Just wanted to clear things, can Azure DevOps be classified as a Platform as a Service. Since it is a cloud service it should be categorized into IaaS but it eliminates the middleware/OS in pipeline. If not then where does it go in the cloud services area? IaaS/SAAS?
Thanks.
Azure DevOps is SaaS for end users (Developers,PM,QA and other stakeholder). In the backend, all the services offer by "Azure DevOps" may run on VMs or Physical server. That mean Microsoft point of view, they may use combination of IaaS & PaaS solution for this platform. Ultimately all services running on VM or physical server.
Its a SaaS, since you are buying a service, not a platform, not virtual machines.
From learn.microsoft.com
Based on the on-premises capabilities, with additional cloud services, we manage your source code, work items, builds, and tests. Azure DevOps uses platform as a service (PaaS) infrastructure and many Azure services, including Azure SQL, to deliver a reliable, globally available service for your development projects.
So according to Microsoft it is PaaS.

for me sometimes, the number of Azure Services, is overwhelming. What is really annoying is that you can't find two lines of description, which explains the concrete uses cases for the different Azure Service.
So does someone know the difference between Azure Deployment Environments and Azure DevTest Lab? Does someone have concrete use cases for this two Azure Services?
Cheers,

Azure Deployment Environments empowers development teams to quickly and easily spin up app infrastructure with project-based templates that establish consistency and best practices while maximizing security. This on-demand access to secure environments accelerates the stages of the software development lifecycle in a compliant and cost-efficient way.

and
Azure DevTest Labs is a service for easily creating, using, and managing infrastructure-as-a-service (IaaS) virtual machines (VMs) and platform-as-a-service (PaaS) environments in labs. Labs offer preconfigured bases and artifacts for creating VMs, and Azure Resource Manager (ARM) templates for creating environments like Azure Web Apps or SharePoint farms.

Hope this helps!
My Application Architecture
I already have a working SQL Server integrating , Analyzing and reporting applications deployed on my on-premise server. Now I am planning to deploy the same reporting application into Azure cloud. I am planning to move this application to cloud.
My Exploration
When I am exploring I found the data factory for data integration and transform services and later can publish to any BI tools. I was reading the data factory documentations from the following link,
https://learn.microsoft.com/en-us/azure/data-factory/introduction
From here I understood that I can use Azure data factory and I can perform data integration and transforming using Connect And collect stage , Transform Enrich and publish stages. And Also we can use BI tools after publishing this.
Related with moving from on-premise to Azure Cloud, I had felt some confusions. I am adding below
My Confusion
Without using Azure's Data factory service , Is possible deploy my all service packages (SSIS/SSRS/SSAS) in my own Azure VM infrastructure like what I did in on-premise machine ?

Yes, you can install all the service packages in your Azure VM when you create the VM. See this description:
Azure virtual machines allow you to deploy a wide range of computing
solutions in an agile way. You can deploy virtually any workload and
any language on nearly any operating system - Windows, Linux, or a
custom created one from any one of the growing list of partners.
You can just treat the virtual machine in Azure as your machine on-premise. The difference is you cannot care about the hardware and Azure will maintain it for you. You can also control the permission of your VM with the Azure Service Principal. See more details about the Azure VM.
Team,
I have a complete running cloud service application upgraded to latest Azure SDK version and unfortunately need to dump this into a CSP subscription. But I came to know that Azure CSP supports only the Azure Resource Manager model, the cloud service is a classic deployment model. So we cannot create a cloud service within a CSP subscription.
Is there any other alternative within Azure CSP to using "cloud service" so that we can migrate with minimal changes. Please help
Firstly, here are some good reads on Microsoft Docs to help comparing the options available and make decisions based on your requirements:
(I mean requirements like Hosting features, Service Limits, 3rd party software installation and RDP access is required or not, Network isolation to a separate VNET is required or not, Cost considerations, minimum SLA, Regions available, instant deployment and auto-scaling, state management etc.):
Azure App Service, Virtual Machines, Service Fabric, and Cloud Services comparison
Decision tree for Azure compute services (This one covers a big spectrum.. simple virtual machines, Batch, Functions, Containers, AKS, ServiceFabric)
Criteria for choosing an Azure Compute Service
Also know that when looking for alternatives, it's not uncommon to make use of multiple compute or other Azure service options by breaking up an older solution into parts at the time of such migration (for e.g. A serverless compute option like Azure Function + Service Fabric + something else if needed).
Generally speaking (and without knowing much about your application from your question currently), Azure App Service and Service Fabric could be considerations IMHO when migrating from an existing Cloud Service, but this is exactly where detailed requirements help you in decision making.
On a side note, here is a list of Azure Services available in CSP - Available Azure services in Azure CSP
I published a web api in Azure via Visual Studio. I would like to know if it is PaaS or IaaS.
When I search for the answer, I find lot of definitions about the PaaS and IaaS.
But I did not find where it is clearly defined which services found in Azure portal are PaaS and Which are IaaS?
Thanks.
With best regards,

IaaS (Infrastructure as a Service):
Cloud infrastructure services, known as Infrastructure as a Service (IaaS), are made of highly scalable and automated compute resources. IaaS is fully self-service for accessing and monitoring things like compute, networking, storage, and other services, and it allows businesses to purchase resources on-demand and as-needed instead of having to buy hardware outright.
PaaS (Platform as a Service):
Cloud platform services, or Platform as a Service (PaaS), provide cloud components to certain software while being used mainly for applications. PaaS provides a framework for developers that they can build upon and use to create customized applications. All servers, storage, and networking can be managed by the enterprise or a third-party provider while the developers can maintain management of the applications.
Source: SaaS vs PaaS vs IaaS: What’s The Difference and How To Choose
In short: with IaaS you use infrastructure (mostly VMs, networking, ...) from your cloud provider that you manage yourself. With PaaS you use an abstraction layer on top of some infrastructure where you do not manage the underlying infrastructure itself. You only manage the application and its data.
If you've deployed to an App Service, you're using PaaS. If you've deployed to a VM that you manage and runs IIS, you're using IaaS.
Another interesting read: What is PaaS?
I have a Azure benefit from my Visual Studio with MSDN subscription.
Microsoft doesn't host MySQL servers in Azure, but I can create a DB from ClearDB through the Azure Portal.
Questions
Is this services included in my benefit?
Can I "Buy" a custom domain with my benefit?
You can provision a VM and deploy MYSQL, this would be included in your benefit but maybe expensive.
You can provision SAAS services like ClearDB via Azure Marketplace but generally billing is separate. When you provision a third party service there is normally a FREE TIER available. If moving to a PAID TIER generally this is billed separately from your Azure Payment methods I have found. Point being , depends on the service you are provisioning. Best bet is to ask the service provider sales channel.
