Valuable Features

AWS Lambda provides serverless scalability, cost efficiency, and integrates with AWS services, supporting multiple languages with high performance.
Spot by Flexera optimizes cloud costs, manages resources efficiently, and integrates with AWS, improving scalability and decision-making with AI.
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
As it is serverless, AWS Lambda has more scope for building scalable architectures.
Consultant at Deloitte
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.

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.
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.
