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
2.7
Amazon ECS provides cost-efficient, scalable solutions, enabling organizations to reduce expenses and optimize resource allocation with a pay-as-you-go model.
Sentiment score
7.9
Spot by Flexera cut compute costs by 75%, saved over 500,000 euros annually, and improved flexibility and operations.
This saving is achieved since, with EC2, the entire virtual machine must be running regardless of workload, whereas Fargate eliminates this cost.
Chief Technology Officer at Looplex SA
By using Spot by Flexera across a year, we were able to save more than 500,000 euros.
License manager at a financial services firm with 10,001+ employees
Our technology predicts demand, selects the cheapest instance mix, sizes the workloads appropriately, and scales it automatically based on policy, resulting in significant savings by reducing manual work and enhancing our flexibility, which has helped accelerate our deployments.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
I cannot share the exact number, but I can share the figure that my EC2 and EKS compute cost reduced by around 65 to 75% with Spot.
Dev Ops Engineer at a construction company with 11-50 employees

Sentiment score
7.9
Amazon ECS customer service is generally positive, with rapid responses, enterprise support praise, and appreciated friendliness despite occasional delays.

I would rate the customer support a nine out of ten.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
We did not have to use it many times, but the few times that we did use it, it was very fast and very useful.
License manager at a financial services firm with 10,001+ employees

Lead Developer at Virtual Restaurant Solutions
It is also a very easy tool to connect to different data sources and different servers since it is open source.

The stability of Amazon Elastic Container Service is excellent.
Chief Technology Officer at Looplex SA
Amazon Elastic Container Service is mostly very stable.
General Manager at Vodafone Idea Ltd.
In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used.
License manager at a financial services firm with 10,001+ employees
 

Room For Improvement

Amazon ECS struggles with usability, pricing complexity, and management, demanding improvements in security, reliability, and seamless user experience.
Spot by Flexera could improve through storage cost optimization, better integrations, enhanced UI guidance, timely updates, and Kubernetes insights.
Currently, when scaling with Amazon Elastic Container Service, I have to choose between monitoring CPU or memory usage to scale up or scale out; there is no option to monitor both simultaneously.
Chief Technology Officer at Looplex SA
When it comes to new-age services around AI, particularly in the areas of LLMs and genomics, these services are not fully available in our region's availability domain.
General Manager at Vodafone Idea Ltd.
A lower price for Amazon Elastic Container Service would be better, but it is comparable to other offerings in the market, so it is on par in that sense.
Head of Products at a tech services company with 51-200 employees
Continuously making advancements based on customer feedback.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
Spot could be improved by adding features that help identify data to optimize storage costs by detecting datasets within our environment based on criteria such as age and usage.
AVP DevOps and Product Support at a recruiting/HR firm with 1,001-5,000 employees
More guided onboarding would help teams adopt advanced features faster.
Dev Ops Engineer at a construction company with 11-50 employees
 

Setup Cost

Amazon ECS offers cost-effective pay-as-you-go pricing, competitive with Azure, cheaper than Google, based on CPU and memory usage.
Users praise Spot by Flexera's pricing for its competitiveness and convenience, rating it highly against market alternatives.
Amazon Elastic Container Service is quite cheap compared to Google, particularly for hosting databases.
Chief Technology Officer at Looplex SA
Our customers often do a trade-off between requiring services at particular SLA levels and being willing to pay a premium price to us as partners.
General Manager at Vodafone Idea Ltd.
The pricing is reasonable and convenient, and the value it offers is completely in line with what I am spending.
Dev Ops Engineer at a construction company with 11-50 employees
I was aware of different pricing, setup costs, and licensing across the company.
License manager at a financial services firm with 10,001+ employees
 

Valuable Features

Amazon ECS offers scalable, cost-effective container management with easy AWS integration, simplifying deployment and enhancing reliability with Fargate.
Spot by Flexera optimizes cloud costs, manages resources efficiently, and integrates with AWS, improving scalability and decision-making with AI.
It inherently offers scalability by default, without our IT teams needing to take the extra load to make the services available for our end users.
General Manager at Vodafone Idea Ltd.
Main benefits that Amazon Elastic Container Service provides include saving maintenance costs in terms of saving time, and since it auto scales, we save on infrastructure costs by running at lower instances when it is not heavily used.
Head of Products at a tech services company with 51-200 employees
Availability is the most valuable feature because if containers are hosted on Amazon Elastic Container Service, they are truly available and do not go down.
Manager, Engineering at a retailer with 10,001+ employees
Spot's automated cost optimization works by continuously analyzing the workload and applying policies to minimize cloud spend without sacrificing performance.
Global Hyperscaler Alliances Director at a tech vendor with 1,001-5,000 employees
The fact that it can mix dozens of instance families dynamically is something which the AWS native autoscalers simply cannot do.
Dev Ops Engineer at a construction company with 11-50 employees
Spot helps us detect such changes within AWS at least one hour prior, allowing us to have a mitigation plan in place and host other servers within the same setup to avoid impacting the application.
AVP DevOps and Product Support at a recruiting/HR firm with 1,001-5,000 employees

Featured Reviews

AG
Lead Developer at Virtual Restaurant Solutions
Starts strong with functionalities but reveals cost limitations
The main challenge with Amazon Elastic Container Service is the significant learning curve. Everything mentioned took months to understand. It is not for the faint of heart. Though they have graphical interfaces and numerous dashboards that help create all the services graphically, learning to use Bash can be challenging. Because these are headless servers by nature, there is no graphical interface. It is not similar to Windows where you can hit the start button and look for your program, or Mac where you can look for programs on your desktop. Instead, users must understand this new paradigm of a Linux headless server, which requires using command-based prompts for builds and development.
Bruna Müller - PeerSpot reviewer
License manager at a financial services firm with 10,001+ employees
Centralized asset data has transformed how we manage licenses and make cost-saving decisions
One problem that we faced using Spot by Flexera is that in certain servers, the data was not being updated correctly, and we had a certain delay. For example, someone was using a computer, and then this user received a new one. In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used. We had a couple of IT assets that were not being used, and we had this information in our internal servers, but Spot by Flexera was not able to update on time. We had to fix this information manually.
