Daniel Wichinescki - PeerSpot reviewer
Has supported production deployments and simplified permission management though could reduce monitoring costs
For Azure Kubernetes Service (AKS), we only used it to orchestrate the Kubernetes pods. We didn't use the other features. We only used the environment to start our application. I utilized the automatic scaling capabilities. The integration with Azure Active Directory helped with the security of our applications. I think Amazon EKS is better. EKS is the best because there are many features to use for scaling and to control the environments.
Felipe Giffu - PeerSpot reviewer
An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Quotes from Members

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

Pros

"We are not yet fully public cloud-native, however, Azure Kubernetes Service promises interesting scalability and flexibility for the future."
"The product serves the purpose of helping streamline our company's application deployment and scaling processes."
"We like how easy it is to create the resources in this solution, thanks to how easy the UI is to use."
"The solution's technical support is excellent."
"Compliance is easy right out-of-the-box with integration to Azure Security, Azure Active Directory, and Azure Policies."
"The most valuable feature is the autoscaling and self-healing."
"In your experience, how has the integration of Azure Active Directory with Azure Kubernetes Service (AKS) helped enhance the security of application?"
"I have enjoyed working with all the features."
"CoreOS Clair's best feature is detection accuracy."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
 

Cons

"AKS has the potential to enhance pricing by enabling us to explore ways to increase cost transparency. However, it's important to note that this refers to computation costs rather than client costs. Our objective is to optimize efficiency and minimize unnecessary expenses. Therefore, we aim to identify which services within the platform can benefit from improved consumption patterns. This is the focus of our ongoing research, with the goal of maximizing computational power within the cluster. We aim to avoid situations where resources are reserved but not utilized effectively. Additionally, our strong emphasis on security ensures that we adhere to all relevant compliance standards, bolstering our overall trustworthiness."
"More control over Infra scanning can be introduced."
"The solution's cost could be cheaper."
"The product needs to support a UI dashboard. I have to execute every single command to check the status of services which takes time."
"The engineering team can reduce the management of the platform itself by improving the data plane part of the system to upload more management."
"One area that could be improved is the Azure CLI. It would be beneficial if they could abstract some of the complexities related to deployment scripts and make them a part of Azure CLI."
"The setup process could be more user-friendly, and additional documentation would be beneficial."
"AKS could enhance its functionality by introducing a blueprint feature that streamlines and expedites the process. With a blueprint, users can leverage pre-defined configurations, including some common survey elements, reducing the need for extensive customization and allowing us to focus on our core business activities. Additionally, if the blueprint covers security aspects, it would be greatly beneficial, as it eliminates the need for us to build security expertise from scratch. Currently, we encounter challenges during cloud onboarding, security implementation, and adapting to Kubernetes. Although Microsoft may not consider these as their direct responsibility, providing a blueprint similar to what they offer to developers would be highly advantageous."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
 

Pricing and Cost Advice

"Azure Kubernetes Service (AKS) is an expensive solution"
"The pricing of the solution is same as Azure Stack."
"The pricing of the solution is dependent on the choice of virtual machines, specifically the amount of memory required. There are various options available, ranging from around twenty-five to even more choices to select from. This flexibility allows you to customize the pricing based on your specific needs. From my perspective, virtual machines in the cloud tend to be slightly more expensive compared to virtual machines offered directly by data centers. However, this cost is offset by the benefits of a managed service. Taking the overall picture into account, the managed service approach is advantageous. The pricing for the platform can vary, typically ranging from three hundred euros per month to two thousand euros per month, depending on the specific requirements and setup you choose."
"Azure Kubernetes Service offers a pay-as-you-go licensing model."
"We could spend as little as $25 or $30 a month on Kubernetes Services, compared to the typical $100 a month expenditure for a virtual machine."
"As you scale your operations, AKS becomes more cost-effective."
"We are facing a significant challenge regarding OEM licensing. The issue arises from the fact that certain licenses required for our own purposes are not provided by Microsoft's licensing. Consequently, we are unsure about the most suitable mobile license provisioning model offered by third-party providers."
"It is not expensive."
"CoreOS Clair is open-source and free of charge."
