Valuable Features

Amazon ECS offers scalable, cost-effective container management with easy AWS integration, simplifying deployment and enhancing reliability with Fargate.
Spot by Flexera offers cost optimization, Kubernetes management, and security compliance with intelligent autoscaling, AWS integration, and AI-driven insights.
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.
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
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
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'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
One use case we plan to implement within the next few months is the overall commitment savings, which we used to manage manually, but with Spot, it automatically helps us detect when and what kind of instances to purchase, making it easier for us to manage our overall commitment for the savings plan.

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.
KS
Dev Ops Engineer at a construction company with 11-50 employees
Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently
I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing. Overall, I think Spot is a really good and stable tool.
