Teradata and Amazon EMR are direct competitors in the data management and big data analytics space. Teradata has the upper hand in robust parallel processing and analytics, while Amazon EMR stands out for its cloud integration and flexibility with AWS services.
Features: Teradata is known for its powerful parallel processing capabilities, reliable architecture, and extensive analytics options suitable for complex tasks. It incorporates features like fast query execution, a highly scalable and robust environment, and comprehensive solutions for in-database analytics and workload management. On the other hand, Amazon EMR benefits significantly from seamless integration with AWS services, providing a highly scalable managed environment that supports multiple frameworks like Hadoop, Spark, and Hive. It is appreciated for easy cluster resizing and flexible deployment options.
Room for Improvement: Teradata users often point out the need for better transactional processing and improved cloud integration, alongside more competitive and flexible pricing options. Amazon EMR users emphasize the need for better cost management, more effective monitoring tools, and quicker startup times, as well as enhanced service integration and debugging potential.
Ease of Deployment and Customer Service: Teradata primarily supports on-premises and hybrid deployments and offers reliable technical support, although some users report delays. For Amazon EMR, which is mainly cloud-based, AWS's infrastructure allows easy scaling and deployment. Its customer service is highly appreciated for being consistent and well-integrated across AWS products, offering reliable support for cloud-first strategies.
Pricing and ROI: Teradata is often praised for its performance but comes at a high cost, which users justify with its superior capabilities and potential ROI. Conversely, Amazon EMR is recognized for its flexible pay-as-you-go pricing model which accommodates dynamic usage, making it cost-efficient and attractive for those seeking scalable cloud solutions.
At least fifteen to twenty percent of our time has been saved using Teradata, which has positively affected team productivity and business outcomes.
Independent research showed that Teradata VantageCloud users achieved an average ROI of 427% across three years with payback under a year, demonstrating the platform's ability to deliver a strong financial return.
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%.
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.
I would rate the technical support from Amazon as ten out of ten.
The customer support for Teradata has been great.
They are responsive and knowledgeable, and the documentation is very helpful.
Customer support is very good, rated eight out of ten under our essential agreement.
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 flexibility allows organizations to scale according to their needs, balancing performance, cost, and compliance requirements.
This expansion can occur without incurring downtime or taking systems offline.
Regular updates, patch installations, monitoring, logging, alerting, and disaster recovery activities are crucial for maintaining stability.
Its massively parallel process architecture allows the platform to distribute workload efficiently, enabling organizations to run heavy analytic queries without compromising speed or stability.
I find the stability to be almost a ten out of ten.
The workload management and software maturity provide a reliable system.
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.
I have thoughts on what would be great to see in the product, such as AI/ML features or additional options.
I want to highlight two features for improvement: first, storing data in various formats without requiring a tabular structure, accommodating unstructured data; and second, adding AI ML features to better integrate Gen AI, LLM concepts, and user-friendly experiences such as text-to-SQL capabilities.
Unlike SQL and Oracle, which have in-built replication capabilities, we don't have similar functionality with Teradata.
The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts.
Costs are involved based on cluster resources, data volumes, EC2 instances, instance sizes, Kubernetes, Docker services, storage, and data transfers.
I would rate the price for Amazon EMR, where one is high and ten is low, as a good one.
Teradata is much more expensive than SQL, which is well-performed and cheaper.
Initially, it may seem expensive compared to similar cloud databases, however, it offers significant value in performance, stability, and overall output once in use.
Role-based access control (RBAC), strong audit and compliance features, high availability, fault tolerance, and encrypted data at rest and in-transit are key features.
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 functionality because we can deploy and get Spark functionality over Hadoop.
The features at Amazon EMR that I have found most valuable are fully customizable functions.
Teradata's security helps our organization meet compliance requirements such as GDPR and IFRS, and it is particularly essential for revenue contracting or revenue recognition.
Its architecture allows information to be processed efficiently while maintaining stable performance, even in highly demanding environments.
It facilitates data integration, where we integrate and analyze data from various sources, making it a powerful and high-quality reliable solution for the company.
