Review summaries and opinions

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

ROI

Sentiment score
3.4
Amazon EKS offers cost-effective scalability and efficiency, though some consider EC2 costs high; GKE transitions save costs for some.
Sentiment score
7.3
Microsoft Defender for Cloud boosts security and efficiency, integrates with Azure, reduces costs, prevents breaches, and offers proactive defense.
Initially, not having them resulted in an unoptimized solution. However, with these tools in place, we witnessed a reduction of costs by approximately a third—if it was $100 beforehand, we brought costs down to $25.
We have cost explorer available, and a bill forecast based on usage allows us to determine whether resources are underutilized or overutilized.
It's a fast deployment, with very good documentation, and it's really helpful.
Defender proactively indexes and analyzes documents, identifying potential threats even when inactive, enhancing preventative security.
Identifying potential vulnerabilities has helped us avoid costly data losses.
The biggest return on investment is the rapid improvement of security posture.
 

Customer Service

Sentiment score
6.0
Amazon EKS users praise support responsiveness and integration but note inconsistencies and higher costs for larger enterprises.
Sentiment score
6.5
Microsoft Defender for Cloud support is responsive at higher levels, but experiences vary with mixed satisfaction due to delays.
We didn't need to manage etcd and those control management tools; it's totally handled from the AWS side, making it very beneficial.
I believe there should be a recovery solution available for at least a few hours so that we might bring it back.
They will set up a call, guide us, or provide solutions regarding integration with AWS or Amazon EKS.
Since security is critical, we prefer a quicker response time.
The support team was very responsive to queries.
They understand their product, but much like us, they struggle with the finer details, especially with new features.
 

Scalability Issues

Sentiment score
5.3
Amazon EKS offers efficient resource management with automatic scaling, suitable for diverse environments and large-scale deployments.
Sentiment score
7.7
Microsoft Defender for Cloud is scalable, integrating across environments effortlessly, suitable for all enterprise sizes with flexible performance.
The ability to scale based on requirements by deploying additional containers is a strong point for Kubernetes.
This allows us to scale our applications or APIs as needed, offering reliability through the automation of scaling processes.
If any node is not ready, the cluster autoscaler ensures that it is removed from the AWS auto-scaling group and replaces it with a new node in the cluster.
We are using infrastructure as a code, so we do not have any scalability issues with Microsoft Defender for Cloud implementation because our cloud automatically does it.
It has multiple licenses and features, covering infrastructures from a hundred to five hundred virtual machines, without any issues.
Defender won't replace our endpoint XDR, but it will likely adapt and support any growth in the Microsoft Cloud space.
 

Stability Issues

Sentiment score
6.5
Amazon EKS offers stable, reliable performance with high stability ratings, resolving past connectivity issues through AWS's efficient management.
Sentiment score
7.6
Microsoft Defender for Cloud is stable and reliable, with minimal issues mainly during updates, ensuring strong user satisfaction.
There are multiple availability zones in the regions, meaning no single point of failure.
The control plane is quite stable in Amazon EKS, and I find it to be 100% available.
We haven't faced any challenges, and it consistently delivers on its committed SLA.
Defender's stability has been flawless for us.
Microsoft Defender for Cloud is very stable.
Microsoft sometimes changes settings or configurations without transparency.
 

Room For Improvement

Amazon EKS needs stability, competitive pricing, better integration, simplified setup, and improved UI, networking, and documentation.
Microsoft Defender for Cloud users seek better automation, clarity, integration, AI features, and comprehensive analytics for improved security management.
Simplifying these will enable more people, not just those with strong foundational knowledge, to work effectively with these services.
Amazon EKS can be improved by having the maintenance of Kubernetes versions managed better, as everything is handled by the Kubernetes team and possibly a separate team at AWS.
Adding logging would be a valuable improvement.
Microsoft, in general, could significantly improve its communication and support.
It would be beneficial to streamline recommendations to avoid unnecessary alerts and to refine the severity of alerts based on specific environments or environmental attributes.
The artificial intelligence features could be expanded to allow the system to autonomously manage security issues without needing intervention from admins.
 

Setup Cost

Amazon EKS provides flexible pricing with potential high costs; optimal for large enterprises needing effective cost management strategies.
Microsoft Defender for Cloud is scalable, offering free and paid versions with costs averaging $15 monthly per server.
The EKS service itself is free, but you will incur costs for the VMs used as nodes in that cluster.
If you want to monitor costs effectively, applying separate tools and acting accordingly in advance is essential.
I appreciate the overall pricing model of AWS, where you pay based on usage, which allows for a clear understanding of costs associated with services.
Every time we consider expanding usage, we carefully evaluate the necessity due to cost concerns.
We appreciate the licensing approach based on employee count rather than a big enterprise license.
Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters.
 

Valuable Features

Amazon EKS offers easy, scalable Kubernetes management with AWS integration, enhancing deployment, efficiency, security, and multi-cloud versatility.
Microsoft Defender for Cloud enhances security with AI-based threat detection, multi-cloud support, and a unified portal for comprehensive management.
The most beneficial aspect of Amazon EKS is that it helps manage the Kubernetes master node, so I don't need to maintain the master node, including tasks like upgrading.
The main benefits that I received from using Amazon EKS are that it is a managed cluster and offers simplicity.
By default, if you just install Amazon EKS, you can deploy your application, but to have it enterprise-ready, you have to configure a number of other things that will boost productivity.
The most valuable feature for me is the variety of APIs available.
This feature significantly aids in threat detection and enhances the user experience by streamlining security management.
The most valuable feature is the recommendations provided on how to improve security.

Has enabled seamless infrastructure configuration while improving identity integration and monitoring capabilities
It has been since 2019 that I started using Amazon EKS. At that time, it was completely new, and many people were not using it just yet; it started from version 1.21, and right now we are on 1.33. Recently, 1.34 has been launched, but it's not yet available in the service catalog; we can see only 1.33. A lot of improvements have been made. We had numerous add-ons to install manually because Kubernetes is a completely different service than AWS cloud provider, and everyone has opted to use it. After opting, there is an identity that you have to maintain—one at Kubernetes level and one at the AWS provider level. You have to maintain one identity at IAM level and one within the cluster, Amazon EKS. A few things do not make sense within the add-ons, many of the secret providers that read the secret from Secrets Manager and then mount it as a volume. We use a service called EBS CSI driver, which reads the secrets or sensitive data from Secrets Manager and then mounts it as a volume to the pod at runtime. However, that doesn't have a dynamic feature where, if any changes happen in the secrets, it can read and populate in the environment. Sometimes consider your RDS password or OpenSearch password rotates. Amazon EKS doesn't have that feature to read the dynamic one and consider that the password has changed overnight; there is no functionality from the provider to see the changes and then restart the pod or fetch the new value. This often leads to downtime of 12 or even 6 hours, depending on when you realize it, so that needs improvement. Nonetheless, mostly on the add-on side, they have developed a lot; earlier we were installing them manually, but now with EKS auto mode, many things VPC CLI and pod identity service—around four plugins—are installed by default, which is a good thing. However, I believe there should be some solution that is self-contained, covering generic use cases. With the 1.33 release, they have addressed most of my earlier concerns, but I am still looking for some improvements, particularly in CloudWatch monitoring. In IT, we manage two aspects: either the system or the application. Currently, the application logs and monitoring are not very robust in CloudWatch; you can only find things if you are familiar with them. Fortunately, we are familiar, as most of the monitoring involves two types of databases: one is a time series for monitoring data, and the other is an indexing solution for a streaming service. This means we need to get the logs from each node, index them, and populate them on a screen. That part remains a separate service, but if they managed it within Amazon EKS service, where the monitoring is consolidated in one place, you wouldn't need to rely on Prometheus, Grafana, or different services. It would be advantageous to have a consolidated platform for EKS, as Kubernetes is leveraged; monitoring and logging should also be integrated simply by enabling parameters or tags. This would create a self-contained platform where people can onboard and start using it. Currently, I still need to enable logging and monitoring among other things myself; that shouldn't be the case after six or seven years in the market. On a scale from 1 to 10, I would rate Amazon EKS tech support an eight. Some individuals have a deep understanding of the services and can identify potential bottlenecks, especially with load balancer endpoints and certificate management. The shift from NGINX to AWS load balancers has diminished many previous issues. However, not every support engineer meets the same level of expertise, hence why I rate it a solid eight, which I consider decent.

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.
