Professional services boost confidence but pricing and user-friendliness need attention

We have multiple solutions such as SimpliVity, Nutanix, and DXRail, which are all part of our Ansible-based system. It gives us more confidence and we can control our groups effectively. The solution is not particularly user-friendly for novice administrators, making it challenging to understand certain aspects. Templates are not readily available, requiring users to build their own worksheets and everything from scratch. This is a main decentralization we observe compared to VMware. We have tested various solutions including Rancher, RHEL, Canonical from SUSE, and the bare metal version from RHEL direct. Since pricing is not a major concern, we chose the best fit for our application, which was specifically designed for this particular platform.

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

"The setup was straightforward and it took one hour to deploy."

"The most valuable feature is the autoscaling and self-healing."

"Azure Kubernetes Service is pretty robust in terms of scalability and auto-scaling fixes."

"It employs high availability."

"The Front Door and Service Bus are the most vital features"

"I have enjoyed working with all the features."

"Its support team resolves technical issues accurately."

"AKS is easy to use. We can scale up and down as needed with AKS, which saves us money on our cloud costs."

More Azure Kubernetes Service (AKS) pros

"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

"If any customer uses a traditional code, the code-level changes take a lot of time."

"The costs could be optimized in some way."

"More control over Infra scanning can be introduced."

"In terms of cost perspective, they could make the product more affordable."

"The initial setup of AKS is complicated. The setup depends on the cluster, nodes, and lots of other things. There are also lots of extremely critical small devices. Moreover, you will have to pay them even while setting up the solution. It is not like you setup first and then pay for it."

"Sometimes, it fails to provide specific metrics."

"It just loses out because you have less access to it programmatically, with less technical or customizable access."

"The technical support could be faster."

More Azure Kubernetes Service (AKS) cons

"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

"The cost of the solution is extremely high. Both Amazon and Azure cost extremely high. Given the basic features like when they are coming over the cluster nodes, we think over ten times before giving the solution to clients. No matter how many offerings the solution provides, it becomes so much of a burden that you are not even getting back your invested money from customers."

"The product follows a pay-as-you-go pricing model which is good for small enterprises. You need to pay only for the services that you use."

"It is an expensive solution."

"You pay for what you use."

"It is not expensive."

"It is expensive compared to other vendors."

"The price of AKS is expensive. We pay approximately $10,000 monthly."

"The product is expensive in terms of scalability."

Overview

Azure Kubernetes Service (AKS) is a fully managed container orchestration service provided by Microsoft Azure. It simplifies the deployment, management, and scaling of containerized applications using Kubernetes. With AKS, developers can focus on building applications while Azure takes care of the underlying infrastructure. It offers features like automatic scaling, monitoring, and security, ensuring high availability and reliability. AKS integrates seamlessly with other Azure services, enabling easy integration with existing workflows. It also provides a flexible and open-source environment, allowing developers to use their preferred tools and frameworks. With AKS, organizations can accelerate their application development and deployment processes, while reducing operational overheads.

Microsoft

Clair is an open source project for the static analysis of vulnerabilities in appc and docker containers.

Vulnerability data is continuously imported from a known set of sources and correlated with the indexed contents of container images in order to produce lists of vulnerabilities that threaten a container. When vulnerability data changes upstream, the previous state and new state of the vulnerability along with the images they affect can be sent via webhook to a configured endpoint. All major components can be customized programmatically at compile-time without forking the project.
