Virtual Machine scale sets
Virtual machine scale sets are an Azure compute resource that you can use to deploy and manage a set of identical VMs. With all VMs configured the same, virtual machine scale sets are designed to support true autoscale. No pre-provisioning of VMs is required. For this reason, it's easier to build large-scale services targeting big compute, big data, and containerized workloads. As demand goes up, more VM instances can be added. As demand goes down, VM instances can be removed. The process can be manual, automated, or a combination of both.
Containers are lightweight, virtualized application environments.
App Service
is a PaaS
Functions are ideal when you're concerned only about the code running your service and not the underlying platform or infrastructure. They're commonly used when you need to perform work in response to an event (often via a REST request), timer, or message from another Azure service, and when that work can be completed quickly, within seconds or less.

Total control over the operating system (OS).
The ability to run custom software.
To use custom hosting configurations.
Move to the cloud with VMs
VMs are also an excellent choice when you move from a physical server to the cloud (also known as lift and shift). You can create an image of the physical server and host it within a VM with little or no changes. Just like a physical on-premises server, you must maintain the VM. You update the installed OS and the software it runs.
Azure Batch is another service for scale
Azure Batch enables large-scale parallel and high-performance computing (HPC) batch jobs with the ability to scale to tens, hundreds, or thousands of VMs.

Starts a pool of compute VMs for you.
Installs applications and staging data.
Runs jobs with as many tasks as you have.
Identifies failures.
Requeues work.
Scales down the pool as work completes.
Containers are a virtualization environment. Much like running multiple virtual machines on a single physical host, you can run multiple containers on a single physical or virtual host. Unlike virtual machines, you don't manage the operating system for a container. Virtual machines appear to be an instance of an operating system that you can connect to and manage, but containers are lightweight and designed to be created, scaled out, and stopped dynamically.
Azure Container Instances
Azure Kubernetes Service
Azure Container Instances offers the fastest and simplest way to run a container in Azure without having to manage any virtual machines or adopt any additional services. It's a platform as a service (PaaS) offering that allows you to upload your containers, which it runs for you.
The task of automating, managing, and interacting with a large number of containers is known as orchestration. Azure Kubernetes Service is a complete orchestration service for containers with distributed architectures and large volumes of containers. Orchestration is the task of automating and managing a large number of containers and how they interact.
Containers are often used to create solutions by using a microservice architecture.
Azure App Service
App Service enables you to build and host web apps, background jobs, mobile back-ends, and RESTful APIs in the programming language of your choice without managing infrastructure. It offers automatic scaling and high availability.
Azure App Service costs
You pay for the Azure compute resources your app uses while it processes requests based on the App Service plan you choose.
Azure Functions
Abstraction of servers
Event-driven scale

Timers, for example, if a function needs to run every day at 10:00 AM UTC.
HTTP, for example, API and webhook scenarios.
Queues, for example, with order processing.
Micro-billing:
With serverless computing, they pay only for the time their code runs. If no active function executions occur, they're not charged. For example, if the code runs once a day for two minutes, they're charged for one execution and two minutes of computing time.

No infractructure
Scalability
Pay only for use
With Functions, you write code to complete each step.
With Logic Apps, you use a GUI to define the actions and how they relate to one another.
Windows Virtual Desktop
Windows Virtual Desktop on Azure is a desktop and application virtualization service that runs on the cloud. It enables your users to use a cloud-hosted version of Windows from any location. Windows Virtual Desktop works across devices like Windows, Mac, iOS, Android, and Linux.
Provide the best user experience
Several devices or web client
lokks like a native user profile
Enhance security
Windows Virtual Desktop provides centralized security management for users' desktops with Azure Active Directory (Azure AD). You can enable multifactor authentication to secure user sign-ins. You can also secure access to data by assigning granular role-based access controls (RBACs) to users.
Simplified management
Performance management
Windows Virtual Desktop gives you options to load balance users on your VM host pools. Host pools are collections of VMs with the same configuration assigned to multiple users.
Multi-session Windows 10 deployment
Windows Virtual Desktop lets you use Windows 10 Enterprise multi-session, the only Windows client-based operating system that enables multiple concurrent users on a single VM.
How can you reduce costs with Windows Virtual Desktop?
Bring your own licenses
Bring your eligible Windows or Microsoft 365 license to get Windows 10 Enterprise and Windows 7 Enterprise desktops and apps at no additional cost.
If you're an eligible Microsoft Remote Desktop Services Client Access License customer, Windows Server Remote Desktop Services desktops and apps are available at no additional cost.
Save on compute costs
Buy one-year or three-year Azure Reserved Virtual Machine Instances to save you up to 72 percent versus pay-as-you-go pricing. You can pay for a reservation up front or monthly. Reservations provide a billing discount and don't affect the runtime state of your resources.
