Containers, including Docker containers, run apps and their dependencies in resource-isolated processes, boosting development speed and efficiency.
This post would provide insights into planning a container deployment, an essential cog in managing real-world artificial intelligence (AI) projects.
Why Plan a Container Deployment
Azure Containers enables packaging and running applications in a loosely isolated environment, called a container. Containerization facilitates effective management of application dependencies, ensuring they do not conflict with other dependencies. Further, Containers support portability across different platforms and clouds, ensuring consistent operation regardless of the environment.
Components Of a Container Deployment In Azure
Container deployment in Azure involves employing different Azure services. The main components include:
- Azure Container Instances (ACI): Offers the fastest and simplest way to run a container in Azure, without requiring any virtual machine provision or higher services management.
- Azure Kubernetes Service (AKS): Allows for management of a hosted Kubernetes service. Kubernetes orchestrates the units of containers that constitute applications.
- Azure Machine Learning: Provides a cloud-based environment that empowers developers to train, deploy, automate, manage, and track ML models.
Steps To Planning a Container Deployment
While planning a container deployment, consider the steps below.
- Determine application requirement: Evaluate the needs of your application. Determine whether your application can run on a single container or require multiple containers in a coordinated environment such as Kubernetes.
- Choose the right Azure Service: If you’re running a simple application not requiring orchestration, Azure Container Instances (ACI) would serve. Conversely, if you’re operating a complex app requiring container coordination, opt for Azure Kubernetes Service (AKS).
- Decide on a development platform: Choose a locally based Docker engine for container image creation, or leverage Azure Pipelines that support continuous integration and delivery.
- Plan for scalability: Plan how to manage workload increase. AKS can be used for automatic application scaling.
- Network Planning: Design your network considering elements like IP addressing, container groups, and DNS name labeling.
- Configuring data persistence: Plan how your application’s data will be stored and accessed. Use Azure File Share to provide a persistent storage volume.
- Management and Monitoring: Implement Azure Monitor and Azure Log Analytics to keep tabs on applications and underlying infrastructure.
Example of Deploying a Container in Azure
Here is an example of running a container using Azure Container Instances.
First, you need to have Azure CLI installed. Once you have it, login to your Azure account:
az login
Next, create a resource group:
az group create --name myResourceGroup --location eastus
Then, deploy a container instance:
az container create --resource-group myResourceGroup --name mycontainer --image mcr.microsoft.com/azuredocs/aci-helloworld --dns-name-label aci-demo --ports 80
This will pull a container image from Microsoft Container Registry, which runs a simple web app listening on port 80.
In conclusion, container deployment takes the pain out of managing application dependencies and facilitates the portability of applications across different platforms and clouds. It is a crucial aspect of the AI-102 exam and the overall Azure AI Solution implementation.
