Venu Boddu - PeerSpot reviewer
Manage infrastructure automation and smooth application deployment with robust auto-scaling capabilities
Kubernetes is highly valuable for its node-based setup, which allows for the running of multiple pods. This feature is essential for infrastructure automation and application deployment. Kubernetes also offers rollback control and auto-scaling capabilities, which are crucial for maintaining an application's availability even if nodes or pods go down. Additionally, Kubernetes supports load balancing to distribute traffic efficiently across multiple pods.
Vibhor Goel - PeerSpot reviewer
A single tool for complete visibility and addressing security gaps
Currently, issues are structured in Microsoft Defender for Cloud at severity levels of high, critical, or warning, but these severity levels are not always right. For example, Microsoft might consider a port being open as critical, but that might not be the case for our company. Similarly, it might suggest closing some management ports, but you might need them to be able to log in, so the severity levels for certain things can be improved. Even though Microsoft Defender for Cloud provides a way to temporarily disable certain alerts or notifications without affecting our security score, it would be better to have more granularized control over these recommendations. Currently, we cannot even disable certain alerts or notifications. There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place. Additionally, enabling Defender for Cloud at the resource group level, rather than only at the subscription level, would be beneficial.

Quotes from Members

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

Pros

"Having fast storage classes is very important."
"I like that it gives you all the flexibility, for example, auto-scaling. Everything is figured out exactly right. It manages all your workloads without much intervention. It can scale in, scale out, and with security. Everything looks pretty good compared to the old legacy way of working."
"Kubernetes is scalable and the elasticity is sustainable."
"The scanning and support network."
"I found it to be an excellent solution for application deployment. It's great for containerization."
"I like the replication center and the configuration."
"The implementation, and the way that they can, with a few clicks, load hundreds of machines without any trouble is very useful."
"The Desired State Configuration is a handy feature; we can deploy a certain number of pods, and the tool will ensure that the state is maintained in our desired configuration."
"When we started out, our secure score was pretty low. We adopted some of the recommendations that Security Center set out and we were able to make good progress on improving it. It had been in the low thirties and is now in the upper eighties."
"The security policy is the most valuable feature for us. We can go into the environment settings and attach any globally recognized framework like ISO or any benchmark."
"Defender for Cloud provides a prioritized list of remediations for security issues, reducing risk and improving security operations."
"Microsoft Defender for Cloud has improved our security poster by at least 100 percent."
"Threat protection is comprehensive and simple."
"The solution is quite good and addresses many security gaps."
"Microsoft Defender for Cloud is a valuable tool that integrates seamlessly with Azure Policy and our Security SIEM, simplifying implementation and enhancing security posture."
"Defender for Cloud is a plug-and-play solution that provides continuous posture management once enabled."
 

Cons

"They need to focus on more security internally."
"The virtual machines should be GUI-based"
"The setup and operation of the product should be simplified."
"The dashboard, monitoring, and login need improvements."
"The support could be faster at resolving issues."
"There is a feature called Terraform and, based on the reviews I have read, it could be improved."
"One feature I would actually like to see is the network monitoring part. When we talk about communities, it's mostly the computer side. But it does have some enhancements on the networking side which they have recently released. I would like to see more enhancement where we can monitor the networks of the Kubernetes cluster or the Kubernetes workloads."
"One thing I noticed is when you have multiple deployments and your node count increases beyond eight or nine, the container creation process doesn't copy properties correctly."
"The documentation and implementation guides could be improved."
"Support needs to be highly responsive, especially in large enterprise environments."
"Sometimes, it's very difficult to determine when I need Microsoft Defender for Cloud for a special resource group or certain kinds of products. That's not an issue directly with the product, though."
"There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place."
"The initial setup is not actually so complex but it feels complex because there are many add-ons. There are many options and my team needs to be aware of all of these changes happening on the backend which is a distraction."
"Most of the time, when we log into the support, we don't get a chance to interact with Microsoft employees directly, except having it go to outsource employees of Microsoft. The initial interaction has not been that great because outsourced companies cannot provide the kind of quality or technical expertise that we look for. We have a technical manager from Microsoft, but they are kind of average unless we make noise and ask them to escalate. We then can get the right people and the right solution, but it definitely takes time."
"I recommend that they extend the scope for legacy infra assets."
"Defender could provide more in-depth visibility into vulnerabilities and services. For instance, we wanted to scan Azure NetApp for sensitive data, but they didn't have that feature. It was only for storage accounts. I want Azure Defender features to cover all Azure resources rather than a few."
 

Pricing and Cost Advice

"The solution is open source and has no fees."
"The solution itself is open-source, so there is no cost attached to it. However, it requires a virtual machine to operate, which does come at a cost; a choice of a pay as you go model, or a monthly charge via an enterprise agreement. There is a pricing calculator available, where organizations can determine the level and number of virtual machines required, and how much that will cost."
"You need to pay for a license if you buy branded products. For example, if you take the services from Azure, AWS, or Google, the price of the Kubernetes cluster is inclusive of the service that's being offered to us on a pay-and-use model."
"There is no licensing fee."
"I am using the solution's open-source version."
"There is a license to use Kubernetes."
"We use the solution's open-source version."
"Kubernetes is open source. But we have to manage Kubernetes as a team, and the overhead is a bit high. Compared with the platforms like Cloud Foundry, which has a much less operational overhead. Kubernetes, I have to manage the code, and I have to hire the developers. If someone has a product, a developer should know exactly what he's writing or high availability, and all those things may differ the costs."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"There is a helpful cost-reducing option that allows you to integrate production subscriptions with non-production subscriptions."
"Understanding the costs of cloud services can be complicated at first. As with a lot of things in the cloud, it can be quite hard to understand the end cost, but it becomes clearer over time. Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something. It is clever marketing, and there is room for improvement there. There should be clarity from the start."
"The pricing and licensing of Microsoft Defender for Cloud have been good for us. We appreciate the licensing approach based on employee count rather than a big enterprise license."
"Azure Defender is a bit pricey. The price could be lower."
"The cost of the license is based on the subscriptions that you have."
"We only use the free tier, so we haven't faced any pricing, setup costs, or licensing challenges."
"Although I am outside of the discussion on budget and costing, I can say that the importance of security provided by this solution is of such importance that whatever the cost is, it is not a factor."
