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

"There are many good features. I feel that the scale-out features, like replica sets, are very good. The number of running containers can be autoscaled."
"It is a very good solution for deploying microservices in an application. It has a lot of freedom in it, which makes it very interesting. It is also web-enabled. You can run services in other virtual applications and virtual machines."
"The self-serving feature allows our developers to grab a container and complete testing."
"Kubernetes offers a lot of great features such as scalability and great portability of applications."
"There's a lot of community support if you need to get help."
"The best thing about Kubernetes is orchestration. It is very good. We will not see much downtime unless there are some human errors. We do not see much downtime or issues with the container or automation."
"The solution has many valuable features but the most impressive is the ability to scale an application and continuously monitor if all the components of the application are functioning correctly."
"I found it to be an excellent solution for application deployment. It's great for containerization."
"The dashboard is very good. It gives our clients a lot of information and allows them to have a complete overview of the system. Everything is visible in one glance."
"The most valuable feature for me is the variety of APIs available."
"Provides a very good view of the entire security setup of your organization."
"Microsoft Defender for Cloud has significantly enhanced our overall security posture by approximately 20 to 25 percent."
"It isn't a highly complex solution. It's something that a lot of analysts can use. Defender gives you a broad overview of what's happening in your environment, and it's a great solution if you're a Microsoft shop."
"The most valuable feature is the regulatory compliance aspect, where we utilize predefined initiatives like NIST. Alert management is another useful feature. Alerts are directly integrated with our email or DevOps board for easy viewing, allowing us to identify problem areas efficiently."
"The UX and UI are very good. Users have more of a taste for Microsoft UI."
"The scalability of Microsoft Defender for Cloud is very good."
 

Cons

"Kubernetes can be used for most companies, but for some companies that may be too small, it may not be worth the investment, as it is expensive."
"Lacks some scalability and more user-friendly operability."
"The management needs to be improved."
"Kubernetes can improve by providing a service offering catalog that can be readily populated in Kubernetes."
"Overall, it's very powerful, but there are also a lot of complexities to manage."
"The setup process could be improved as it's quite complex, especially for newbies."
"Currently has a very minimal UI for certain things."
"Absence of a built-in feature for local API creation"
"The documentation could be much clearer."
"An area where Microsoft Defender for Cloud could be improved is in getting away from having multiple menus that do the same thing, which seems imposing when looking at it."
"Pricing could be improved. There are limited options based on pricing for the government."
"For improvements, I'd like to see more use cases integrated with Microsoft Sentinel and support for multi-cloud environments beyond just Azure."
"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."
"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."
"If a customer is already using Okta as an SSO in its entire environment, they will want to continue with it. But Security Center doesn't understand that and keeps making recommendations. It would help if it let us resolve a recommendation, even if it is not implemented."
"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters. It could be cheaper."
 

Pricing and Cost Advice

"The solution requires a license to use it."
"It's an affordable solution"
"If you have a solid AKS and a solid DevOps process, you'll automatically get an ROI, not just in terms of cost but also in how quickly you can see your business application progress."
"The price of Kubernetes could be lower. However, it is less expensive than VMware Tanzu. Additionally, technical support is expensive. The overall cost of the solution is approximately $1,000 annually."
"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."
"Kubernetes is an open-source solution that can be free. We have some distribution with licenses, such OpenShift and Tucows in Amazon. They are billing services."
"We use the solution's open-source version."
"Kubernetes is open-source. Kubernetes is free, but we're charged for AWS utilization."
"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."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"While we pay for any additional features, the pricing seems competitive, though I am not involved in the specific cost details."
"I rate Microsoft Defender a three out of ten for affordability. The price could be a little lower."
"There are two different plans. We're using the secure basic plan, but we have used the end security plan as well. There are additional costs, but it gives us more functionalities compared to the basic plan."
"The price of the solution is good for the features we receive and there is an additional cost for Microsoft premier support. However, some of my potential customers have found it to be expensive and have gone on to choose another solution."
"The cost of the license is based on the subscriptions that you have."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
