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
5.1
Elastic Search enhances efficiency and scalability, offering significant returns through improved performance, cost savings, and early issue alerts.
Sentiment score
6.5
Implementing Redis improved transaction efficiency, reduced costs, enhanced performance, increased developer effectiveness, and supported scalability for organizations.
We have not purchased any licensed products, and our use of Elastic Search is purely open-source, contributing positively to our ROI.
It is stable, and we do not encounter critical issues like server downtime, which could result in data loss.
The main benefits observed from using Elastic Search include improvements in operational efficiency, along with cost, time, and resource savings.
 

Customer Service

Sentiment score
6.2
Elastic Search's support features strong documentation and community resources, with positive technical support, though response speed can improve.
Sentiment score
1.0
Users rarely contact Redis support, but those who do find it knowledgeable, with satisfaction levels ranging from moderate to excellent.
The customer support for Elastic Search is one of the best I have ever tried.
They have always been really responsible and responsive to my requests.
I would rate technical support from Elastic Search as three out of ten.
 

Scalability Issues

Sentiment score
7.2
Elastic Search offers robust scalability and storage, but faces challenges with complex configurations, cost, and large database management.
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.
Since we're on the cloud, whenever we need to upgrade or add resources, they handle everything.
We haven't encountered any problems so far, and there is the potential for auto-scaling.
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, with rare issues resolved through proper resource planning and management in large data scenarios.
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.
When you put one keyword, everything related to that keyword in your ecosystem will showcase all the results.
Redis is fairly stable.
 

Room For Improvement

Elastic Search needs enhancements in security, scalability, user support, pricing, UI, and easier integration for beginners.
Enhancements in documentation, user-friendliness, scalability, security, cloud integration, and support are desired improvements for Redis.
This can create problems for new developers because they have to quickly switch to another version.
It is primarily based on Unix or Linux-based operating systems and cannot be easily configured in Windows systems.
The consistency and stability of Elasticsearch are commendable, and they should keep up the good work.
Data persistence and recovery face issues with compatibility across major versions, making upgrades possible but downgrades not active.
 

Setup Cost

Elastic Search is open-source, but enterprise costs vary; expertise and feature needs influence overall expenses significantly.
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.
Elastic pushes clients to buy the Enterprise edition instead of the Premium edition, and we don't see the value in that other than to spend more money more quickly.
The pay-as-you-go model is advantageous for the organization, as we only pay for what we utilize.
Since we use an open-source version of Redis, we do not experience any setup costs or licensing expenses.
 

Valuable Features

Elastic Stack is praised for its speed, scalability, integrations, analytics, flexibility, open-source nature, and excellent documentation.
Redis provides fast data access with caching, geolocation, JSON, and supports scalability, high availability, and efficient event-driven 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.
The speed with which Elastic Search is able to search through all of the documents we place into it is quite remarkable, as we search through 65 billion documents in less than a second in most cases, on a constant consistent basis.
It functions similarly to a foundational building block in a larger system, enabling native integration and high functionality in core data processes.

Boosted search efficiency through real-time querying and seamless indexing for high-volume product data
We are using AWS for our solutions. In AWS, we are heavily using Redshift and Glue. We focus more on vector searches and boosting the keywords, and all those features we are using heavily. In search, the key parameter that we boost up during indexing is essential. We self-implement Elastic Search in our e-commerce application. We are not currently doing a regex setup for RAG Playground, but there is a plan to do that. We are more into vector searches when it comes to how effectively the hybrid search capability meets our needs for combining traditional keyword and vector searches. Regarding the workflow, we are using the API for real-time inference because lots of data is being loaded at real-time on the application, and it is working well for us. I can definitely recommend Elastic Search to be used wherever you have consumer search capabilities needed in a large or scalable manner because it is very effective. I would rate Elastic Search an eight out of ten.
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.
