Has supported seamless microservices deployment and improved cost control through managed infrastructure

Microsoft Azure Container Service includes being a very mature tool and a fully managed service, making it ready to use. You can simply opt for it and use it. As a managed service, you don't need to take care of the managed components. You only need to take care of whatever user-space you are managing. All the managed components are taken care of by Microsoft. They provide support for different upgrade operations, and anything related to managed components such as the controller nodes, those things they can take care of automatically. This is actually a very challenging task that is handled by Microsoft itself. Microsoft Azure Container Service has positively impacted my organization as it is a very mature tool and, when using the Azure platform, it's highly secure. It can offer end-to-end encryption and take care of all kinds of compliance. It also offers Azure Defender for Cloud that can provide security recommendations on a daily basis, making it a very mature product.

Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently

I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing. Overall, I think Spot is a really good and stable tool.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable features are that it is simple, and the compression of the data."

"Storage is one of the most beneficial features of cloud providers, specifically Azure because when you are working in their cloud environment, you can easily use a storage interface and a storage object that is provided by Microsoft Azure. In a local environment, you have to be involved in establishing and setting up distributed storage file systems for containers which are very difficult and complex. In a cloud environment, you are not concerned about the storage and the dashboard provides you with storage objects with high availability."

"Microsoft Azure Container Service has a good level of stability."

"The most valuable feature is that you don't have to maintain the infrastructure."

"Visualization is the most important feature."

"It's a great product if you are in a Microsoft environment."

"Microsoft Azure Container Service helps to optimize resources and save costs by allowing our product to handle it through this containerization method."

"The product makes things easier since it's self-managed. Therefore, there is less administration workload and operational costs."

"The solution helps us to manage and scale automatically whenever there is a limit to the increase in the application workflow."

"Cost saving is the main benefit, and the manual effort required for reviewing and purchasing savings plans and other RIs is something we do not have to manage manually now, as we get automatic suggestions from Spot."

"My compute costs have reduced, capacity and production output have increased, and my overhead for maintaining custom scripts or doing some of the tasks manually has been saved."

"The solution offers both block access and file access, making it a nice solution for customers."

"Spot has positively impacted our organization by automating cloud resource management, which has significantly cut costs and improved efficiency."

Cons

"Since the product is fully managed, it is expensive."

"The customization is an area that needs improvement."

"In the future, I would like to see it generalized and have the ability to better integrate with open-source tools."

"In terms of the container strategy, they need to make it more compliant with the Linux OS."

"f Microsoft Azure can provide GUI dashboards for end-users and administrators to work separately to manage all the Kubernetes clusters without a need to connect to Azure environments and through CLI it would be better."

"I wasn't very impressed with the documentation."

"Standard support could be more helpful and responsive."

"I have not seen a return on investment yet."

"The solution doesn't have support from OCI, and it should start working to onboard OCI."

"There are no particular areas for improvement I can identify."

Pricing and Cost Advice

"Microsoft Azure Container Service has costs but in the container environment, there are no costs because it is open source and we are using Docker as the container engine in the master and worker nodes established in the Azure environment."

"The costs depend on the resources that you use, and there is a cost-management system to help calculate it."

"The solution's pricing is reasonable."
