Microsoft has recently introduced a new service for Azure customers. Called Azure Container Instances, the solution gives developers tools to add containers without needing to maintain virtual machines on Azure.
Azure Container Instances has launched in six regions through in the United States, Southeast Asia, and Europe. Microsoft says users can currently create containers for free, but a pricing structure will start from July 1, 2018.
Developers use containers to host applications in virtualization, and Microsoft is already deep in this area with Azure Container Service. The hosting service needs virtual machines to work, but the new Instances solutions does not:
Microsoft will continue to supply Azure Container Service as some customers will need it. The company says which container service you choose will depend on how much isolation is needed. Despite this, Corey Sanders, corporate vice president of Azure said this week the Instances solution has a “deep security model, protecting each individual container at a hypervisor level which provides a strong security boundary for multitenant scenarios.”
“ACI enables each stage of work to be efficiently packaged as a container assigned with custom resource definitions for agile development, testing, and deployment. By processing the data with ACI rather than statically provisioned virtual machines, you can achieve significant cost savings due to ACI's granular per-second billing.”
Microsoft has also announced the following features for Azure Container Instances:
We have been so excited about this new compute offering since preview, and we have listened to your feedback to shape several important new features including:
- Improved Azure portal experience with metrics, alerts, and container logs/events.
- Execute (EXEC) a command directly in your container to launch an interactive shell.
- Monitor CPU and memory utilization of Linux containers through Azure Monitor.
- Configure a reliable endpoint per container by placing a DNS name label through the REST API or Azure CLI 2.0.
- Stream container logs with Azure CLI 2.0: Read your container state and log output by attaching to your container from Azure CLI 2.0.
- Container restart policies: Designate containers to always restart, restart only on failure, or never restart.
- Various volume types for Linux containers including Azure Files, gitRepo, emptyDir, and secret.
- Availability across 6 regions including West US, West US 2, East US, West Europe, North Europe, and Southeast Asia.
- Uptime SLA of 99.9% for any Container Group.
