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
6.4
Elastic Search offers high ROI, efficiency, and cost-effectiveness, with significant time-saving and security benefits despite some licensing costs.
Sentiment score
6.5
Redis enhances speed, reduces costs by 40%, boosts efficiency, and offers scalability, stability, and high availability, increasing customer trust.
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
6.5
Elastic Search's customer service is praised for responsiveness and knowledge, but complex issue support may require improvement.
Sentiment score
1.0
Most users lack direct Redis support experience; reviews vary from knowledgeable and fast to low-rated service.
I would rate technical support from Elastic Search as three out of ten.
 

Scalability Issues

Sentiment score
7.3
Elastic Search is scalable and integrates well, but challenges exist with large datasets and disaster recovery under rapid scaling.
Sentiment score
7.7
Redis is highly scalable, supporting clustering and cloud integration, making it ideal for enterprise and growing data needs.
I would rate its scalability a ten.
I can actually add more storage and memory because I host it in the cloud.
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
7.7
Elastic Search is stable and reliable, though version updates and data management can affect performance under stress.
Sentiment score
7.7
Redis is highly reliable, handling heavy loads with strong uptime, requiring minimal maintenance, and proving dependable across infrastructures.
It was consistent and reliable in our usage.
The data transfer sometimes exceeded the bandwidth limits without proper notification, which caused issues.
Redis is fairly stable.
 

Room For Improvement

Elastic Search needs improvements in security, scalability, usability, stability, integration, support, and enhanced features for a better user experience.
Redis struggles with cluster development, cloud integration, documentation, user experience, and requires enhancements in security and enterprise features.
The consistency and stability of Elasticsearch are commendable, and they should keep up the good work.
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.
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 open-source version can incur back-end costs for advanced features, expertise, and premium support.
Redis offers cost-effective options but may incur additional fees for RAM and managed services, requiring careful cost evaluation.
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 is valued for scalability, fast indexing, powerful analysis, security features, cloud readiness, and strong community support.
Redis offers high-speed in-memory storage, efficient caching, multiple data structures, scalability, and durability for reliable, scalable applications.
Elastic Search makes handling large data volumes efficient and supports complex search operations.
The most valuable feature of Elasticsearch was the quick search capability, allowing us to search by any criteria needed.
I appreciate the indexing capabilities and the speed of indexing in their product, which demonstrates how quickly logs are collected and stored.
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.
