Benefits of a data lake

1. A Closer Look at the Benefits of a Data Lake: Why is it important to architect and integrate the right- fit data lake platform? Data lakes are central repositories that store large volumes of structured, unstructured, and semi-structured data. They are ideal for machine learning use cases and support SQL-based access and programmatic distributed data processing frameworks. Data lakes can store data in the same format as its source systems or transform it before storing it. They support native streaming and are best suited for storing raw data without an intended use case. Data quality and governance practices are crucial to avoid a data swamp. Data lakes enable end-users to leverage insights for improved business performance and enable advanced analytics. www.suntechnologies.com 1 | P a g e

2. Why are data lakes important? A data lake is a powerful tool for businesses to rapidly ingest and analyze new data, enabling faster response to new information and access to previously unavailable data types. This data lake is a popular source for machine learning, enabling discovery- oriented exploration, advanced analytics, and reporting. It consolidates big data and traditional data, enabling analytical correlations across all data. A data lake can store intermediate or fully transformed data, reducing data preparation time and ensuring compliance with data security and privacy policies. Access controls also used to maintain security. A data lake provides many data sources for businesses to explore, analyze, and report on. The Benefits of a Data Lake for Your Business A data lake is a powerful tool that allows organizations to store all data in one place at a low cost, enabling them to make informed decisions based on data. This data democratization allows middle management and other departments to access and make decisions based on the needed data, reducing the time spent on decision-making. Data lakes also provide better quality data, as they offer tremendous processing power and can store multi-structured data from diverse sources. They offer scalability, which is relatively inexpensive compared to traditional data warehouses. They can store logs, XML, multimedia, sensor data, binary, social data, chat, and people data. Schema flexibility is another advantage of data lakes. Hadoop data lakes allow for schema-free or multiple schemas for the same data, enabling better analytics. They also support various languages, such as Hive/Impala/Hawq, which supports SQL but also offers features for more advanced use cases. In summary, a data lake offers numerous benefits for organizations, including better quality data, democratization, scalability, versatility, and support for various languages. By leveraging the power of data lakes, organizations make well-informed decisions and enhance their overall business operations. Exploring the Challenges of a Data Lake Data lakes are emerging technologies that require significant investment and can be challenging to implement. They face challenges such as identifying a use case, organizational hurdles, and technological challenges. Data lakes are often associated with Hadoop, a parallel programming paradigm that HortonWorks uses, which is unsuitable for small datasets. Hadoop is suitable for large but not small datasets, as it stores everything in 260 megabytes. It only supports inserts and updates, making decoupling data and metadata difficult for users.

Choosing the right technology stack for a data lake requires integrating various ingestion, processing, and exploration technologies. No standard rules for security, governance, operations, and collaboration make things more complicated. Additionally, data lakes have hard SLAs for query processing time and data ingestion ETL pipelines. The solution must be scalable from one user to many users and from one kilobyte of data to a few petabytes. As the big data industry changes rapidly, businesses need to select robust enough technology to comply with SLAs. Factors that need to consider while choosing a technology stack include On-Premise, on the Cloud, and Managed Services. Security and compliance data management have become increasingly complex, and robust security measures are crucial to protect company data and customer information. GDPR and CCPA are data privacy laws essential for data lakes, requiring proof of data erasure and removal. The security strategy depends on cloud-based, on-premise, or hybrid architecture, with cloud-based data lakes particularly vulnerable. Robust encryption protocols and controls are necessary to ensure data protection and reputation. Data governance Data governance is crucial for maintaining quality, security, and compliance throughout the organization's lifecycle. Data lake investments may cause conflicting results and data trustworthiness without a framework. A data governance framework ensures consistent rules, standards, and definitions for data analysis. Data quality Managing data quality in a lake is challenging due to the potential for poor data to slip in undetected. Validating lake data is crucial to prevent issues and ensure business activities. Creating data zones based on quality checks can help, such as transferring freshly ingested data to transient zones, where it can have labeled as trusted. Costs Cloud infrastructure costs are a significant concern for business leaders, with 73% reporting C-suite spending and 49% stating higher spending than expected. Factors like supply chain disruptions, energy prices, and lack of competition contribute to these costs. A strong FinOps framework can help control costs while building and managing data lakes. www.suntechnologies.com 3 | P a g e

4. Performance Large data lakes can cause performance issues, such as bottlenecks due to numerous small files and deleted files causing issues. Limitations on processing information units and storage time can cause bottlenecks, affecting analysis and overall performance. Ingestion Data lakes store unprocessed data for later analysis, but improper ingestion can lead to a data swamp. To optimize data ingestion, create a plan, understand the data's purpose, compress data, and limit small files to improve performance. Exploring the Benefits of Data Lakes for Companies Companies increasingly collect more data, necessitating a scalable database for data storage. Data lakes have emerged as a cost-effective solution for big data storage, offering significant cost savings and preventing silos. They provide a central repository for data, making it accessible across the organization. Data lakes also support advanced analytics, enabling businesses to forecast future trends and prepare accordingly. Data lakes are schema-free, allowing for flexibility in data storage in any format. This allows for efficient ETL pipelines without prematurely stripping away vital information. Companies that effectively implement a data lake experience improved business performance, with 24% of data lake leaders reporting strong or highly effective organic revenue growth and 15% experiencing growth in operating profit compared to 11% of followers. Simplifying data collection is another benefit of data lakes. They can ingest data of any format without structure, allowing easy collection and processing for specific use cases. This flexibility allows companies to access more data for advanced analytics and improves overall business performance. The Impact of Data Lakes on Today's Business Rapid ingestion and native format storage are key benefits of data lakes. Raw data refers to data without processing or preparation, with some sources having previously processed data. Data lakes store raw data without processing or preparing it, except for formatting. The native format ensures data remains in the source system's format, but this is not always the best option for data lake storage. Rapid ingestion rarely involves copying data as-is into a file system directory. www.suntechnologies.com 4 | P a g e
