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
5.4
Amazon EMR delivers significant cost savings and efficiency, with some users achieving up to 20% savings and positive ROI.
Sentiment score
8.1
Teradata improved speed, efficiency, and customer satisfaction, achieving significant ROI, enhanced analytics, and reduced staffing needs for users.
At least fifteen to twenty percent of our time has been saved using Teradata, which has positively affected team productivity and business outcomes.
We have realized a return on investment, with a reduction of staff from 27 to eight, and our current return on investment is approximately 14%.
 

Customer Service

Sentiment score
7.7
Amazon EMR support is generally proactive and responsive, though user experiences vary, especially during open-source integrations.
Sentiment score
7.1
Teradata support is highly rated for professionalism and resources, though some users note slow response times and technical support challenges.
They help with billing, cost determination, IAM properties, security compliance, and deployment and migration activities.
We get all call support, screen sharing support, and immediate support, so there are no problems.
The customer support for Teradata has been great.
The technical support from Teradata is quite advanced.
Customer support is very good, rated eight out of ten under our essential agreement.
 

Scalability Issues

Sentiment score
7.4
Amazon EMR is scalable and versatile, though some face resource speed issues and performance differences between environments.
Sentiment score
7.4
Teradata offers exceptional scalability and speed, though some users face challenges with hardware requirements and scaling involvement.
Scalability can be provisioned using the auto-scaling feature, EC2 instances, on-demand instances, and storage locations like block storage, S3, or file storage.
Whenever we need more resources, we can add that in Teradata, and when not needed, we can scale it down as well.
This expansion can occur without incurring downtime or taking systems offline.
Teradata's scalability is great; it's been awesome.
 

Stability Issues

Sentiment score
7.7
Amazon EMR is stable and reliable, with high availability, but could improve slightly to address occasional concerns.
Sentiment score
8.3
Teradata is stable and reliable, with excellent uptime, minimal downtime, and seamless upgrades, though large dataset issues occur.
Regular updates, patch installations, monitoring, logging, alerting, and disaster recovery activities are crucial for maintaining stability.
The workload management and software maturity provide a reliable system.
I find the stability to be almost a ten out of ten.
 

Room For Improvement

Amazon EMR requires improved user-friendliness, stability, monitoring, integration, and pricing adjustments to enhance performance, scalability, and compatibility.
Teradata requires cost-effective improvements in cloud integration, scalability, UI, data processing, analytics, compatibility, support, and pricing.
The cost factor differs significantly. When you run Spark application on EKS, you run at the pod level, so you can control the compute cost. But in Amazon EMR, when you have to run one application, you have to launch the entire EC2.
There is room for improvement with respect to retries, handling the volume of data on S3 buckets, cluster provisioning, scaling, termination, security, and integration between services like S3, Glue, Lake Formation, and DynamoDB.
If the same thing were available in a web interface, that would be really helpful.
If Teradata could provide a list of certified experts, that would be fantastic.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
 

Setup Cost

Amazon EMR pricing is usage-based, perceived higher, but optimizable through instance management and auto-scaling for Big Data tasks.
Teradata offers advanced features and cloud flexibility, though enterprises need careful cost-benefit analysis for its premium pricing.
Cost optimization can be achieved through instance usage, cluster sharing, and auto-scaling.
Initially, it may seem expensive compared to similar cloud databases, however, it offers significant value in performance, stability, and overall output once in use.
Teradata is much more expensive than SQL, which is well-performed and cheaper.
We spent roughly $295,000 on setup costs.
 

Valuable Features

Amazon EMR offers scalable, cost-effective data processing with easy integration, advanced features, and robust management on a cloud-based infrastructure.
Teradata excels in fast query processing, scalability, robust security, and cross-platform integration, enhancing performance and reducing administrative effort.
Amazon EMR helps in scalability, real-time and batch processing of data, handling efficient data sources, and managing data lakes, data stores, and data marts on file systems and in S3 buckets.
Amazon EMR provides out-of-the-box solutions with Spark and Hive.
It has resulted in better performance improvement within our team as we now cover nine business units instead of 18, thanks to the data performance, which has increased data visibility and helped the enterprise achieve a higher rate of internal return on financials.
The first thing that I appreciate about Teradata is its multi-parallel processing. Whatever queries we execute on Teradata, they are blazingly fast, so it offers really fast connectivity.
The data mover is valuable over the last two years as it allows us to achieve data replication to our disaster recovery systems.

Featured Reviews

Prashant  Singh - PeerSpot reviewer
Seamless data integration enhances reporting efficiency and an easy setup
Amazon EMR has multiple connectors that can connect to various data sources. The service charges are based on processing only, depending on the resources used, which can help save money. It is easy to integrate with other services for storage, allowing data to be shifted to cheaper storage based on usage.
Kirk Robinson - PeerSpot reviewer
Has improved data quality, optimized reporting processes, and enabled predictive insights across business units
The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput. We have been testing that, but speed remains one of our key issues. The integration has been awesome because of the platforms and their usage, and usability is great. The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts. If Teradata could provide a list of certified experts, that would be fantastic. I rated Teradata a nine because the main area for improvement is the bandwidth of resources that could assist us in applying to our projects, specifically more certified and expert resources. The market share of Teradata professionals is limited, creating an issue for us.
