4. New infrastructure needed for application
Microservices provide a flexible approach to developing and deploying modern applications. Instead of one large monolithic application, microservices break down applications into smaller components with key features and functions that all communicate with each other. These services are developed and deployed independently by small, focused teams.
This approach results in less dependency among components, making it easier for developers to build, improve, and scale specific parts of an app without risking the whole application. Teams can focus on developing or refining specific capabilities rather than the entire app, opening the door to daily (or even more frequent) updates and additions to an application. This also makes developing and testing software faster and easier.

5. Overview of Azure services
ACI offer significant startup benefits over virtual machines. Azure Container Instances can start containers in Azure in seconds, without the need to provision and manage VMs
Azure Kubernetes Service (AKS) manages your hosted Kubernetes environment, making it quick and easy to deploy and manage containerized applications without container orchestration expertise. It also eliminates the burden of ongoing operations and maintenance by provisioning, upgrading, and scaling resources on demand, without taking your applications offline.
Azure Container Registry allows you to store images for all types of container deployments including DC/OS, Docker Swarm, Kubernetes, and Azure services such as App Service, Batch, Service Fabric, and others. Your DevOps team can manage the configuration of apps isolated from the configuration of the hosting environment.

Azure App Service Web Apps (or just Web Apps) is a service for hosting web applications, REST APIs, and mobile back ends. You can develop in your favorite language, be it .NET, .NET Core, Java, Ruby, Node.js, PHP, or Python.

7. Building own solution that oriented on containers
Create web api core using VS code
dotnet new webapi
Create docker file
FROM microsoft/dotnet:latest
COPY . /api_test
WORKDIR /api_test
RUN ["dotnet", "restore"]
RUN ["dotnet", "build"]
ENV ASPNETCORE_URLS
EXPOSE 5000/tcp
ENTRYPOINT ["dotnet", "run"]
Build container image
docker build --rm -f Dockerfile -t api_test:dev .

8. Building own solution that oriented on containers
Tag to ACR
docker tag acrhub.azurecr.io/api_test:dev
Push to ACR
docker push acrhub.azurecr.io/api_test:dev
Testing container image locally, in ACI, in Web app for containers
Deploy multi-container solution
az group deployment create --resource-group API-TEST --template-file deploy.json

9. Building own solution that oriented on containers
A container group is a collection of containers that get scheduled on the same host machine.
The containers in a container group share a lifecycle, local network, and storage volumes
