ECS-Optimized Windows Reviews

My main use case for ECS-Optimized Windows involves utilizing the machines offered by AWS, which means a workload like the image of Windows, exactly. It is provided by AWS with right-sizing for the CPU options. That is my main case: pre-configured Windows and ECS Windows AMIs. It functions as a container.

For example, if I have completed a project and have installed everything, I have created an image, which is an instance for AWS EC2. My friend can easily use it, and it is very lightweight. We can also set right-sizing and memory efficiency, and we can also tune the CPU. I will do everything and give it to my team.

The best features that ECS-Optimized Windows offers, in my opinion, include fast launching for fast booting. It will launch very fast and it will boot the EC2 instance very fast. It has pre-given snapshots, and the efficiency is also very good, which is about 70%. It will also give us the actual usage analysis. We can analyze the report and reduce the cost. Coming to the storage, it is also good for basic or medium usage.

The usage analysis and reporting have helped me and my team by allowing us to see exactly what my teammate has been using for the past 10 hours and how he is using it. We can check if there is any time that it is still counting when he is taking breaks or something similar, which helps us reduce the cost at that time.

ECS-Optimized Windows positively impacts my organization by reducing our licensing costs because it is providing us with the Windows image. We don't need to take 10 or more licenses. It helps us scale faster for launching or booting the Windows or applications, and in ECS Windows, there is higher application performance.

ECS-Optimized Windows can improve by giving us new generation instances rather than the old generation's AMD chips or other older technology. It should use the new generation instances, and it should also modernize the storage and the file systems that it is using because those are very old and sometimes problematic. It should also improve or add advanced configurations to the things that we are doing so it can help us and give us more efficiency and productivity in our team. It should give us good analysis, particularly more detailed analysis, with the AWS tools because it is operated by AWS. It is cloud-based, and we are getting it from AWS, so they should also integrate it with AWS better.

I have been using ECS-Optimized Windows for 12 to 18 months.

ECS-Optimized Windows is stable.

ECS-Optimized Windows is easily scalable and it is good.

Amazon has good customer support.

I would rate the customer support of Amazon 10 out of 10 because their customer support is very fast and good.

I have been using Docker, but I found better options here. I switched because I found a lesser cost and faster boot-ups, so I shifted here.

I purchased ECS-Optimized Windows through the AWS Marketplace.

We don't have any business relationship with this vendor other than being a customer.

Our teams can scale at least 40% faster than before, accounting for waiting for it to boot and load everything. It can save us the cost on licensing by up to 50% to 60%, for certain. I can guarantee that.

I think ECS includes licenses, so it reduces the stress. Also, the cost is very low, at $0.04 per hour per version of the CPU. We can also get our own license. It follows the BYOL method.

I told you we saved more money because we are reducing the licensing costs, and we are also getting more time now because we don't need to wait for the booting, faster processing, and all. Also, the price is less for this, at $0.04, as I told you, so it is good.

I didn't evaluate any other options because my friend is already using this. My friend has already been using this, so I directly jumped into it.

My advice to others looking into using ECS-Optimized Windows is that they can use it. They can save a lot of time and a lot of money on licensing. It also offers a BYOL method, so it is also beneficial for some people. It is a lesser cost compared to other things. Those are the features. They can easily get into it, it's easily usable, and they can easily get addicted to it. I would rate this product a 9 out of 10 overall.

We use ECS-Optimized Windows to run centralized Windows-based workloads on Amazon ECS, primarily on .NET applications and legacy Windows services that require Windows Server environments.

We used ECS-Optimized Windows to migrate a legacy ASP.NET based internal HR management system into a containerized Windows workload running on ECS. The application included a .NET framework web application, background web Windows services, integration with a Microsoft SQL server based database hosted on Amazon RDS. By containerizing the application and deploying it through ECS, we achieved automated scaling during peak usage, such as payroll processing periods, reduced manual server configuration, and improved deployment consistency across staging and production environments. ECS-Optimized Windows simplified host setup since it came preconfigured with the ECS agent and Windows container support, reducing provisioning time significantly. This project helped modernize a legacy Windows workload while maintaining compatibility with existing .NET dependencies, improving reliability, scalability, and operational efficiency.

The most valuable features of ECS-Optimized Windows are built-in ECS agent configuration, optimized Docker support for Windows containers, seamless integration with Amazon ECS, automatic updates aligned with AWS releases, and compatibility with Windows Server container workloads.

After deploying our Windows workloads using ECS-Optimized Windows on AWS, we saw improved reliability and measurable operational efficiencies. Application uptime increased to over 99.9% due to ECS-managed health checks and automatic task replacement. Deployment time for new releases dropped by nearly 50% compared to manual EC2 cloud-based deployments. We also reduced configuration-related incidents by about 30% because containerized environments ensure consistency across staging and production environments. While Windows instances are generally more expensive than Linux, better scaling during peak workloads helped us avoid overprovisioning, resulting in more controlled and predictable infrastructure costs.

Improvements for ECS-Optimized Windows could include faster Windows patch cycles, a lighter AMI footprint for quicker boot times, better visibility into container-level performance metrics, and improved cost optimization guidance.

I have been using ECS-Optimized Windows for the past six months.

ECS-Optimized Windows achieves scalability through tight integration with Amazon Elastic Container Service on AWS, enabling automatic scaling at both the container and infrastructure levels. At the service level, ECS auto service scaling adjusts the number of running Windows containers based on CPU, memory usage, or custom CloudWatch metrics, ensuring the application can handle traffic spikes efficiently. At the infrastructure level, it integrates with EC2 Auto Scaling groups, allowing Windows instances to automatically scale when the cluster capacity is low and scale in when demand decreases. Additionally, the built-in health checks automatically replace failed containers, improving reliability while maintaining performance under load. Overall, scalability is achieved through automatic container scaling, EC2 instance auto-scaling, multi-availability zone deployment, and health-based task replacement.

Customer support is adequate, and we did not have much interaction with them.

Before, we used Windows workloads directly on standalone EC2 instances without containerization but switched to ECS-Optimized Windows to improve scalability, orchestration, and deployment consistency.

We reduced the environment setup time significantly by eliminating the need to manually configure Windows container hosts, cutting provisioning time from several hours to under 30 minutes per instance.

There is no separate licensing cost for the AMI itself beyond standard Windows Server licensing included in EC2 pricing. Setup costs are minimal, but Windows EC2 licenses are generally more expensive than cloud-based alternatives.

We evaluated Kubernetes-based solutions such as Amazon EKS and traditional VM deployments, but chose ECS for its simpler management model and tighter AWS integration.

My advice for anyone considering ECS-Optimized Windows is to start with a small pilot workload, confirm application container compatibility early, right-size EC2 instances to control Windows costs, set up ECS service auto-scaling and EC2 auto-scaling from day one, and automate patching and AMI updates so Windows hosts stay secure and consistent across environments. I would rate this solution an 8.5 out of 10.

ECS-Optimized Windows is primarily useful if you are looking to use or run an application on a Windows-based system. You could either potentially create your own custom AMI, or you could use an Amazon-managed one. Amazon manages this image, which makes it more convenient to deploy on a Windows environment in containers.

If you are looking to use PowerShell for automation, ECS-Optimized Windows could be quite handy because PowerShell is a Microsoft tool. I have used it this way with PowerShell automation scripts that I have tested to carry out document processing. Because this is optimized for Windows, integrating it with other Microsoft tools is quite convenient. It removes some of the burden of configuring the custom image myself.

I have been considering testing ECS-Optimized Windows for Microsoft Message Queuing. I have not done it before, but I would imagine that would also be a good use case for it because again, it is a Microsoft product which would integrate really well with it.

ECS-Optimized Windows has several best features including the fact that because Amazon manages it, the security features are kept up to date. That is always quite convenient because it removes some of the management for myself. I know Amazon is constantly updating the security. ECS-Optimized Windows also offers quite fast deployment; you do not have to worry about installing custom libraries on the image, because it is already there out of the box. ECS-Optimized Windows monitoring is quite convenient because CloudWatch logging and metrics are already configured with it because it is an Amazon-managed image.

The feature I like the most about ECS-Optimized Windows is probably the security hardening, because Amazon manages it and they regularly update it. I know that the security of the image is kept up to date, which would be cumbersome to manage myself. In terms of improvements, I do not see any from those benefits.

ECS-Optimized Windows has positively impacted my organization because I have been using it for proof of concepts and it increases the speed of running them because I do not have to worry about creating my own image. It also increases the security of it as well.

One problem with ECS-Optimized Windows is that the image size is quite large. This is due to the underlying Windows operating system being a lot larger than Linux variants. Most people would only use a Windows image if they specifically need to use Windows. Otherwise, Linux is quicker and it is cheaper as well. ECS-Optimized Windows also presents vendor lock-in on two accounts. Firstly, you are using the custom AMI, so you have vendor lock-in with AWS. Additionally, because you are operating on the Windows operating system, if you were to develop on Windows over a long period of time, it could make it potentially difficult to migrate to Linux-based operating systems as well. Those are two key drawbacks.

I have been using ECS-Optimized Windows for around one year.

ECS-Optimized Windows is stable. Because it is managed by Amazon, it is kept regularly up to date from a security perspective. There are no performance concerns.

ECS-Optimized Windows is highly scalable. You can have one, or you could have thousands if you want to. The very nature of the image running on EC2 means you could scale it to massive amounts.

I rate the customer support for ECS-Optimized Windows a ten out of ten. It is Amazon support, so if you have enterprise Amazon support, then you have twenty-four-hour, seven days a week coverage.

I have previously used Linux Alpine on AWS. It is great. It is cheap and it is quicker to run because the operating system is lighter. I would not say I necessarily switched to ECS-Optimized Windows, but ECS-Optimized Windows serves a different purpose.

From the time perspective, I have seen a return on investment with ECS-Optimized Windows. Compared to creating my own custom image and then updating the security which could take potentially an hour per month, across the year, I am already saving at least one business day worth of work, which is a great return.

Pricing for ECS-Optimized Windows is good. It is just pay for what you are using. It starts very low. There is no large upfront cost.

I evaluated other options before choosing ECS-Optimized Windows, specifically Amazon Linux. Because I was looking to use Microsoft tools, it just made a lot more sense to go with ECS-Optimized Windows.

I chose a rating of ten for ECS-Optimized Windows because for what it is, it is great. It does exactly what it is meant to do. It is an Amazon-managed image. You do not have to worry about some of the management of it. ECS-Optimized Windows drawbacks are really things which you would already be aware of before you start using it and they are not necessarily things which can even be solved. If you want a quicker and a cheaper operating system, you would not go for Windows, you would potentially go for Linux, for example.

I would say others should use ECS-Optimized Windows if they are looking to run Microsoft tools or Microsoft workloads. If they are looking to run non-Microsoft workloads, you might want to consider running the Linux variant because you might find it cheaper and also quicker in terms of deployment. I give ECS-Optimized Windows an overall rating of ten out of ten.

Our main use case for ECS-Optimized Windows is to host our containerized application, which is essential because earlier, when we had Kubernetes and different clusters, we had to use a different operating system to host Linux-based containers. We got a requirement to host .NET applications and some Windows-based applications in containerized form. During that period, we explicitly installed Windows Server as a worker node, but that was really difficult. When AWS introduced ECS-Optimized Windows, it was a lifesaver for us because it has all the containerized tools pre-installed and all the agents pre-installed. With the help of ECS-Optimized Windows, we deploy our containerized application on top of that.

We are using ECS service from Amazon and within that ECS service, we are using the optimized Windows AMI, which has a pre-configured agent, container runtimes, and several integrations with respect to containers. In our environment, we deploy this ECS cluster using Terraform in AWS and in that cluster, we have multiple EC2s, or nodes, where some nodes are Windows and some are Linux, and ECS-Optimized Windows is used there as well. It is an AMI provided by Amazon, and we host our Windows-based applications on top of those ECS-Optimized Windows hosts. We are using these ECS AMIs in our ECS cluster to host our Windows-based containerized applications.

The best features ECS-Optimized Windows offers include many benefits that I have experienced with switching from regular Windows to ECS containerized virtual machines. First of all, it has all the binaries and libraries we require for the container host pre-installed, meaning it comes with all the installed container runtime, agents installed, and all the integration already done in the AMI itself. It also allows for faster deployment because it is a package containing everything pre-installed, enabling us to deploy the node as fast as we can.

The scaling part is another feature I really appreciate because it is very easy to scale the ECS cluster. ECS-Optimized Windows is an optimized version of a Windows operating system with pre-installed libraries and binaries for containers, such as agents and runtimes. Whenever there is a huge application workload, we have predefined an auto-scaling policy for our ECS cluster, and within a couple of seconds or minutes, the node spins up, scaling up and out instantly.

Another aspect I appreciate is the integration capabilities, optimized for DevOps integration. We integrate with GitHub Actions, Datadog, monitor with CloudWatch, leverage our Elastic Container Registry (ECR), and perform auto-scaling. These are the main things I really appreciate. ECS-Optimized Windows has significantly reduced our operational effort, which is positive for our organization.

Initially, we would bring the operating system, install the container runtime, perform integration, install agents, and now, with ECS-Optimized Windows, everything is pre-installed, meaning it is a package with required libraries for containers. Nowadays, we no longer need to manually set up the server, patch, configure, modify files, or manually deal with recovery. With this AMI, everything is pre-built, and we can directly deploy and use it. ECS-Optimized Windows has saved a lot of our resources. Initially, we needed a couple of resources just to ensure Windows hosts were up with the required configuration for the ECS cluster, but with ECS-Optimized Windows, we no longer have to do that. Operational work is completely reduced, which is the main takeaway. Another aspect is that it is lightweight, making it easy to manage.

In terms of improvement, one issue is that Windows containers are heavier than Linux, which means Windows applications or containers require more resources and take longer to build up or start, and the images are heavy. However, in Windows terms, I really appreciate it. Additionally, there is some complexity regarding networking and image management with ECS Windows, but I find that manageable.

I have been using ECS-Optimized Windows for about two years.

ECS-Optimized Windows is indeed stable and scalable.

In our ECS cluster, we have already configured auto-scaling, which helps scale out and scale in the clusters. Whenever there is a huge workload, the cluster automatically scales out, and when there are idle nodes, it scales in according to the defined policy. The auto-scaling feature in ECS is very helpful for scaling, and this AMI is built in such a way that it can auto-scale.

We have not had many interactions with customer support because there have not been many issues, but overall, customer support is good. We did receive help from them for an application where we had some deployment issues, and their assistance was really good.

Before using ECS-Optimized Windows, we were using direct Windows Server; we explicitly had those Windows Servers for our ECS cluster and containers. In Windows, we do not have many options, so we used Microsoft-provided AMIs, but those did not have all the pre-built libraries and binaries, making ECS-Optimized Windows a good choice for us.

When it comes to compatibility, ECS-Optimized Windows supports almost all Windows-based applications, so it is compatible with Windows-based workloads or applications. I think more input is not needed because we have plenty of documentation available and almost everything is part of the integration we need.

If anyone wants to deploy a Windows-based application, such as .NET Framework or similar, I would really recommend opting for ECS-Optimized Windows AMIs because they have everything pre-built and pre-installed. You will not need to spend a lot of time configuring your host, making ECS-Optimized Windows a worthwhile choice. I think we have covered everything. I would rate this solution a 9 out of 10.
