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
5.9
Organizations had mixed ROI with Elasticsearch; some saved on costs using open-source, while others faced high licensing fees.
Sentiment score
6.5
Implementing Redis improved transaction efficiency, reduced costs, enhanced performance, increased developer effectiveness, and supported scalability for organizations.
The main benefits observed from using Elastic Search include improvements in operational efficiency, along with cost, time, and resource savings.
It is stable, and we do not encounter critical issues like server downtime, which could result in data loss.
We have not purchased any licensed products, and our use of Elastic Search is purely open-source, contributing positively to our ROI.
 

Customer Service

Sentiment score
6.4
Elastic Search's support receives varied feedback, with users favoring community resources and some noting slower official assistance.
Sentiment score
1.0
Users rarely contact Redis support, but those who do find it knowledgeable, with satisfaction levels ranging from moderate to excellent.
I would rate technical support from Elastic Search as three out of ten.
 

Scalability Issues

Sentiment score
7.2
Elastic Search is scalable, especially in cloud environments, but high-volume scalability requires careful planning and infrastructure investment.
Sentiment score
7.7
Redis excels in scalability, efficiently handling large datasets with ease, making it ideal for enterprise-level operations and demands.
I would rate its scalability a ten.
There might be issues regarding data size and scaling, but these can be tuned and improved.
I would rate the scalability of Elasticsearch as an eight.
Data migration and changes to application-side configurations are challenging due to the lack of automatic migration tools in a non-clustered legacy system.
 

Stability Issues

Sentiment score
7.6
Elastic Search is generally stable, but performance can vary due to infrastructure, version changes, and configuration requirements.
Sentiment score
7.7
Redis is stable, reliable under heavy loads, supports high availability, and user ratings reflect strong performance, needing load improvements.
The data transfer sometimes exceeded the bandwidth limits without proper notification, which caused issues.
The stability of Elasticsearch was very high.
Redis is fairly stable.
 

Room For Improvement

Elastic Search requires enhancements in security, scalability, user experience, integration, documentation, and support for enterprise needs.
Enhancements in documentation, user-friendliness, scalability, security, cloud integration, and support are desired improvements for Redis.
The architecture of Elastic Search could be improved as it is complicated for most general users to build up the environment and maintain the cluster.
The consistency and stability of Elasticsearch are commendable, and they should keep up the good work.
This can create problems for new developers because they have to quickly switch to another version.
Data persistence and recovery face issues with compatibility across major versions, making upgrades possible but downgrades not active.
 

Setup Cost

Elastic Search's free version can become costly for enterprises due to premium features, node-based pricing, and scalability challenges.
Redis's open-source core is cost-effective, but enterprise features require a license; managed services start at $5/month.
We used the open-source version of Elasticsearch, which was free.
Since we use an open-source version of Redis, we do not experience any setup costs or licensing expenses.
 

Valuable Features

Elastic Search offers efficient search, scalability, and integration with Kibana and Logstash, providing affordable features and handling diverse data.
Redis provides fast data access with caching, geolocation, JSON, and supports scalability, high availability, and efficient event-driven applications.
The most valuable feature of Elasticsearch was the quick search capability, allowing us to search by any criteria needed.
Elastic Search makes handling large data volumes efficient and supports complex search operations.
Configuring Elasticsearch is much easier compared to comprehending other SIEM tools like Splunk.
It functions similarly to a foundational building block in a larger system, enabling native integration and high functionality in core data processes.

Captures data from all other sources and becomes a MOM aka monitoring of monitors
Scalability and ROI are the areas they have to improve. Their license terms are based on the number of cores. If you increase the number of cores, it becomes very difficult to manage at a large scale. For example, if I have a $3 million project, I won't sell it because if we're dealing with a 10 TB or 50 TB system, there are a lot of systems and applications to monitor, and I have to make an MOM (Mean of Max) for everything. This is because of the cost impact. Also, when you have horizontal scaling, it's like a multi-story building with only one elevator. You have to run around, and it's not efficient. Even the smallest task becomes difficult. That's the problem with horizontal scaling. They need to improve this because if they increase the cores and adjust the licensing accordingly, it would make more sense.
Yaseer Arafat - PeerSpot reviewer
Unmatched Performance and Scalability for Modern Applications
Redis has room for improvement in a few areas. Enhanced tools for managing and monitoring clusters would be beneficial, as would built-in security mechanisms like advanced encryption and granular access controls. Simplifying setup and configuration could make Redis more accessible to new users. Introducing more enterprise-grade features, such as better multi-tenancy support and improved backup and restore capabilities, would also be advantageous. For the next release, it would be great to see enhanced cluster management tools, native multi-region supports for better data redundancy, integrated analytics for deeper insights, AI and ML integration features, and improved developer experience through enhanced SDKs and tools.
