ROI

Sentiment score
4.8
Apache NiFi users experience significant time savings and improved efficiency, although exact cost benefits aren't always quantifiable.
Sentiment score
7.9
Spot by Flexera cut compute costs by 75%, saved over 500,000 euros annually, and improved flexibility and operations.
Thanks to improvements on both our side in how we run processes and enhancements to Apache NiFi, we have reduced the time commitment to almost not needing to interact with Apache NiFi except for minor queue-clearance tasks, allowing it to run smoothly.
Data Engineer at The Kudelski Group
It supports not just ETL but also ELT, allowing us to save significant time.
Team Lead Technical Specialist (Production Support) at a recreational facilities/services company with 11-50 employees
There may be return on investment based on the technology and easily moving our workloads onto Apache NiFi from our previous system.

Scalability Issues

Sentiment score
6.7
Apache NiFi's scalability varies; some users succeed with clusters, while others struggle without Kubernetes, impacting implementation.
Sentiment score
7.6
Spot by Flexera is scalable, adaptable, and open-source, effectively managing AWS expansions and connecting diverse data sources.
Depending on the workload we process, it remains stable since at the end of the day, it is just used as an orchestration tool that triggers the job while the heavy lifting is done on Spark servers.
Manager at a tech company with 10,001+ employees
Scaling up is fairly straightforward, provided you manage configurations effectively.
Data Engineer at The Kudelski Group
Based on the workload, more nodes can be added to make a bigger cluster, which enhances the cluster whenever needed.

Manager at a tech company with 10,001+ employees
Apache NiFi is stable in most cases.
Data Consultant at a comms service provider with 201-500 employees
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

Apache NiFi needs improved integration, UI, scalability, security features, and seamless CI/CD processes for enhanced usability and efficiency.
Spot by Flexera could improve through storage cost optimization, better integrations, enhanced UI guidance, timely updates, and Kubernetes insights.
Apache NiFi should have APIs or connectors that can connect seamlessly to other external entities, whether in the cloud or on-premises, creating a plug-and-play mechanism.
Manager at a tech company with 10,001+ employees
The history of processed files should be more readable so that not only the centralized teams managing Apache NiFi but also application folks who are new to the platform can read how a specific document is traversing through Apache NiFi.
Team Lead Technical Specialist (Production Support) at a recreational facilities/services company with 11-50 employees
The initial error did not indicate it was related to memory or size limitations but appeared as a parsing error or something similar.
Data Engineer at The Kudelski Group
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.

Users praise Spot by Flexera's pricing for its competitiveness and convenience, rating it highly against market alternatives.
The pricing in Italy is considered a little bit high, but the product is worth it.
Partner at a tech vendor with 10,001+ employees
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

Apache NiFi simplifies data flow orchestration with drag-and-drop features, scalability, and integration, enhancing productivity and reliability.
Spot by Flexera optimizes cloud costs, manages resources efficiently, and integrates with AWS, improving scalability and decision-making with AI.
Apache NiFi has positively impacted my organization by definitely bridging the gap between the on-premises and cloud interaction until we find a solution to open the firewall for cloud components to directly interact with on-premises services.
Manager at a tech company with 10,001+ employees
Development has improved with a reduction in time spent being the main benefit; before we needed a matter of days to create the ingestion flows, but now it only takes a couple of hours to configure.
Senior Data Engineer at a tech vendor with 10,001+ employees
The ease of use in Apache NiFi has helped my team because anyone can learn how to use it in a short amount of time, so we were able to get a lot of work done.
Data Consultant at a comms service provider with 201-500 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.

Featured Reviews

YV
architect with 51-200 employees
Unified data flows have simplified large-scale ingestion and have improved SLA reliability
Improvements can be made in the way of the UI. From the deployment perspective, Git configurations are available in 2.6 versions and 2.0 and later versions of Apache NiFi. Before 2.0, templates had to be created and stored in Apache NiFi Registry, which is available. However, templates still need to be imported and exported manually if moving from one environment to another environment. Even in 2.0 versions, although GitHub configurations are available, how it will function needs to be evaluated. Seamless CI/CD deployments are somewhat tricky and challenging when it comes to Apache NiFi with the proper approvals, moving that flow to another environment, and giving the proper RBAC controls. These are areas that could be improved. Documentation is adequate, but the only pain point is the deployment aspect.
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.
