What is Netezza?

Netezza is a data warehouse appliance that provides high-performance analytics and insights for enterprise data. Netezza was acquired by IBM in 2010 and is now part of the IBM Cloud Pak for Data platform. Netezza combines hardware, software, and advanced analytics capabilities to deliver fast, scalable, and reliable data warehousing solutions.

Netezza Architecture

Netezza uses a proprietary architecture called Asymmetric Massively Parallel Processing (AMPP) that combines open blade servers and disk storage with a custom data filtering process using field-programmable gate arrays (FPGAs). The AMPP architecture enables Netezza to process large volumes of data in parallel, while filtering out irrelevant data at the source, reducing the amount of data that needs to be transferred and processed by the central processing unit (CPU). This results in faster query execution and lower resource consumption.

The Netezza appliance consists of two main components: the host system and the Snippet Processing Unit (SPU). The host system is a Linux-based server that manages the database, coordinates queries, and distributes data to the SPUs. The SPUs are independent processing units that store and process data locally. Each SPU has its own FPGA, CPU, memory, and disk. The FPGA performs data compression, decompression, encryption, decryption, and filtering operations on the data before sending it to the CPU for further processing. The CPU executes SQL operations on the filtered data and returns the results to the host system. The memory acts as a cache for frequently accessed data, while the disk provides persistent storage for the data.

The Netezza appliance can scale horizontally by adding more SPUs or vertically by adding more host systems. The appliance also supports high availability and fault tolerance features, such as redundant power supplies, fans, disks, network connections, and host systems. The appliance can automatically detect and recover from hardware failures, as well as balance the workload across the available SPUs.

Netezza Features

Netezza offers several features that make it a powerful and versatile data warehouse solution for various analytics and AI workloads. Some of these features are:

• SQL on Parquet: Netezza supports querying data from Parquet files stored in a data lake without requiring any data movement or transformation. Parquet is an open-source columnar storage format that enables efficient compression and encoding of data. Netezza can leverage its FPGA-based filtering technology to scan Parquet files directly from the data lake and return only the relevant data to the CPU for processing. This feature allows users to access and analyze both structured and unstructured data from a single platform.
• Integration with watsonx.data: Netezza integrates with watsonx.data, a new data store built on a data lakehouse architecture that combines the best aspects of a data lake and a data warehouse. watsonx.data provides a unified, scalable, and open platform for storing and managing all types of data across the hybrid cloud. watsonx.data also supports open formats such as Parquet and Apache Iceberg, as well as integration with various analytics and AI tools. Netezza can query data from watsonx.data using SQL on Parquet capabilities, as well as write back results to watsonx.data for further analysis or sharing.
• Machine learning processing: Netezza supports high-speed and scalable machine learning processing for Python and SQL without moving the data. Users can leverage various libraries and frameworks such as scikit-learn, TensorFlow, PyTorch, Spark MLlib, etc., to build and deploy machine learning models on Netezza. Users can also use Netezza’s in-database analytics functions to perform common tasks such as data preparation, feature engineering, model training, evaluation, scoring, etc., using SQL commands.
• Data security: Netezza provides various features to ensure data security and compliance in the cloud or on-premises environments. These features include data encryption at rest and in transit, data masking, access controls, audit logging, role-based security, etc. Netezza also supports HIPAA-ready deployments for healthcare applications.
• Elastic scaling: Netezza supports elastic scaling of compute and storage resources in the cloud based on workload demand. Users can scale up or down their Netezza instances using a simple command-line interface or a graphical user interface. Users can also use AI-infused elastic scaling to automatically adjust their resources based on workload patterns and performance metrics. Netezza’s elastic scaling also enables granular elastic pricing - users only pay for what they use, no t-shirt sizes.

Netezza Benefits

Netezza provides several benefits for users who want to optimize their analytics and AI workloads and reduce their warehouse costs. Some of these benefits are:

• Faster insight: Netezza delivers faster insight and faster time to value with superior price-performance compared to other data warehouse solutions. Netezza’s AMPP architecture enables faster queries and analytics workloads that can support thousands of concurrent users for real-time insights.
• Simplified management: Netezza simplifies the management and maintenance of the data warehouse by providing a self-managing and self-tuning system that does not require any indexing, partitioning, or tuning. Netezza also provides easy and risk-free upgrades from existing Netezza appliances to the cloud or on-premises deployments.
• Unified data: Netezza enables users to access and analyze data from various sources and formats, such as relational databases, data lakes, watsonx.data, etc., using a single SQL interface. Netezza also supports data integration and transformation capabilities to ensure data quality and consistency across the enterprise.
• Advanced analytics: Netezza empowers users to perform advanced analytics and AI tasks on their data using various tools and languages, such as Python, SQL, R, etc. Netezza also supports in-database analytics functions to enable users to perform complex operations on their data without moving it out of the system.
• Cost efficiency: Netezza reduces the total cost of ownership of the data warehouse by providing a scalable and flexible solution that can adapt to changing business needs and workload demands. Netezza also offers elastic pricing options that allow users to pay only for what they use, without any upfront or hidden costs.

Conclusion

Netezza is a data warehouse appliance that provides high-performance analytics and insights for enterprise data. Netezza combines hardware, software, and advanced analytics capabilities to deliver fast, scalable, and reliable data warehousing solutions. Netezza supports various features such as SQL on Parquet, integration with watsonx.data, machine learning processing, data security, and elastic scaling. Netezza offers several benefits such as faster insight, simplified management, unified data, advanced analytics, and cost efficiency. Netezza is available as a fully managed service on AWS and Azure , as well as self-managed on IBM Cloud and IBM Cloud Pak for Data Systems.
