ROI

Sentiment score
7.1
AWS Lambda offers cost savings and high ROI through its pay-as-you-go model, auto-scaling, and serverless infrastructure.
Sentiment score
7.6
Spot by Flexera enabled substantial savings in compute costs and enhanced efficiency, though ROI may take longer for some.
I have seen a return on investment as I was able to reduce my compute cost by 60 to 65% for some of my applications that needed light temporary processing tasks with ephemeral storage and stateless applications.
Dev Ops Engineer at a construction company with 11-50 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.

Assistant Manager at a tech vendor with 10,001+ employees
Whenever the number of requests increases, the system automatically scales up to the target we have set and scales down once the requests are resolved.
Co Founder And CTO at Gamucopia Creatives
Spot's scalability is quite good, and it can be expanded to multiple environments.
Dev Ops Engineer at a construction company with 11-50 employees
 

Stability Issues

Sentiment score
8.1
AWS Lambda is highly stable, reliable, and integrates well, though limited by timeout constraints, rated 8-9 for stability.
Sentiment score
7.0
Spot by Flexera is mostly stable and reliable, though some users report occasional bugs indicating room for improvement.
 

Room For Improvement

AWS Lambda users desire improved integration, user-friendliness, language support, execution speed, monitoring, setup, customization, and computational capabilities.
Spot by Flexera needs OCI support, better multi-cloud integration, and UI improvements, though it's stable and mature.
AWS Lambda needs to improve cold start time.
Co Founder And CTO at Gamucopia Creatives
Continuously making advancements based on customer feedback.
Global Hyperscaler Alliances Director at a tech vendor 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
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.

Setup Cost

AWS Lambda offers cost-effective, pay-per-use pricing, ideal for low-traffic workloads, with potential cost escalation if unmonitored.
Enterprise users praise Spot by Flexera's pricing and setup, with structured management of licensing, via AWS Marketplace.
The pricing is reasonable and convenient, and the value it offers is completely in line with what I am spending.

Valuable Features

AWS Lambda provides serverless architecture, automatic scaling, seamless integrations, cost efficiency, and simplified deployment for efficient application development.
Spot by Flexera offers cost optimization, Kubernetes management, and security compliance with intelligent autoscaling, AWS integration, and AI-driven insights.
Automatic scaling is a valuable feature. When the number of requests increases, the system automatically scales up to the target we have set and scales down once the requests are resolved.
Co Founder And CTO at Gamucopia Creatives
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

Rajaraman Ramachandran - PeerSpot reviewer
Co Founder And CTO at Gamucopia Creatives
Has enabled us to manage compute resources efficiently while supporting multiple languages
AWS Lambda needs to improve cold start time. Some AWS Lambda functions require a cold start, and if you need AWS Lambda to provide quick responses, you need some of the AWS Lambdas to be always on, which is risky. We need AWS Lambda's cold start time to be reduced so that we can use it much faster than now. We need a better way to handle the cold start. We should be able to start AWS Lambda much before in a predictable way instead of just calling and then having it start.

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.
