This blog will help you discover what differentiates cloud data lakehouse services from a data warehouse and discuss a pragmatic approach to data lakehouse architecture. Also, we will learn if it is an ideal solution for your business.
A Data Lakehouse is a hybrid data storage and processing platform that combines the best of both traditional data warehousing and big data lake technologies. It is designed to address and resolve some of the limitations of traditional data warehouses and data lakes. A data lakehouse is a modern data architecture that is designed to store, process and manage all data, structured and unstructured, at any scale in a centralized repository.
In a data lakehouse, data is first ingested into a data lake, where it can be stored in its raw form. This allows organizations to store large volumes of data at a low cost, without worrying about the structure or format of the data.
Once the data is ingested, it can be transformed and structured using a set of tools and technologies, and then loaded into a data warehouse. This allows organizations to perform complex analytics and run business intelligence queries on the data, using SQL-based tools and techniques.
The Data Lakehouse provides several key benefits to organizations, including:
Improved Data Governance: The Data Lakehouse provides a centralized repository for all data, making it easier to manage data quality and security, and ensure data governance.
Faster Time to Insights: The Data Lakehouse provides fast query performance, making it easier for organizations to explore and process their data, and extract insights.
Better Handling of Unstructured Data: The Data Lakehouse is designed to handle both structured and unstructured data, making it easier for organizations to extract insights from a broader range of data sources.
Lower Total Cost of Ownership: The Data Lakehouse provides a centralized repository for all data, reducing the need for multiple data storage and processing platforms, which can help lower the total cost of ownership.
One example of a company using a Data Lakehouse is Uber. Uber collects and stores massive amounts of data from its ridesharing and food delivery platforms. The Data Lakehouse provides a centralized repository for all this data, making it easier for Uber to extract insights and make data-driven decisions.
Another example is Netflix, which uses a Data Lakehouse to store and manage all its customer data, including viewing habits and preferences. The Data Lakehouse provides Netflix with a centralized repository for all this data, making it easier for the company to extract insights and make data-driven decisions.
Recent Gartner report indicates that the Data Lakehouse market is expected to grow rapidly over the next several years, with the global Data Lakehouse market size expected to reach $3.3 billion by 2024, growing at a CAGR of 28.3% from 2019 to 2024.
The Data Lakehouse combines the benefits of both. It allows for the raw data to be stored in its original format, making it easy to access and analyze, but also provides the structure needed for efficient querying and analysis. This structure is achieved through data cataloguing and indexing, which allows for faster performance and improved governance.
A Data Warehouse is a centralized repository that collects, integrates, and stores vast amounts of data from various sources, including transactional systems, operational databases, and external sources. It enables organizations to have a single view of their data and provides the ability to analyze and report on the data in a meaningful and actionable way.
However, despite its many benefits, Data Warehouses also have their limitations. Some of the most significant limitations include:
Cost: Setting up and maintaining a Data Warehouse can be expensive, particularly for organizations with limited budgets. The hardware, software, and staffing costs involved in setting up a Data Warehouse can be prohibitively high for some organizations.
Complexity: Data Warehouses can be complex to set up and manage, particularly for organizations that are new to the technology. The process of integrating data from different sources and transforming it into a format that can be easily analyzed can be time-consuming and challenging.
Data Quality: Data Warehouses rely on the quality of the data that is fed into them. If the data is incorrect, incomplete, or outdated, the results generated from the Data Warehouse will be unreliable. This can result in poor decision-making and can have serious consequences for the organization.
Scalability: As the volume of data grows, Data Warehouses can become increasingly difficult to manage and maintain. This can result in longer processing times and increased costs.
Data Latency: Data Warehouses are designed to store historical data, which can be a significant limitation for organizations that need real-time data. The process of extracting, transforming, and loading data into a Data Warehouse can take time, and by the time the data is available, it may be out of date.
A data lake is a centralized repository that enables organizations to store large amounts of structured and unstructured data at any scale. The data lake is designed to handle a variety of data types, including transactional data, operational data, log data, social media data, and machine-generated data.
The main advantage of cloud data lake solutions is that it provides a cost-effective and scalable solution for storing large amounts of data. This allows organizations to store data for a longer time, making it easier to analyze data trends over time and make informed decisions.
However, as with any technology, a data lake also has its limitations. Here are some of the most significant limitations of a data lake:
Lack of data governance: Data lakes tend to be large, and without proper governance, it can be challenging to identify, track, and manage the various data sets within the lake. Data quality can suffer if there is no control over data ingestion, transformation, and management.
Complex data integration: Integrating data from various sources is one of the key objectives of a data lake. However, the process of data integration can be complex and time-consuming, especially when the data sets are vast and diverse. Ensuring that the data is properly organized, tagged, and indexed is crucial to its accessibility and usability.
High costs: Implementing and maintaining a data lake requires significant investments in infrastructure, storage, and data management tools. Furthermore, as the amount of data stored in the lake increases, the costs of managing and processing that data also increase.
Difficulty in data discovery: Finding the right data within a data lake can be a challenge, especially if the data is not properly organized, tagged, or indexed. Users can waste a lot of time trying to locate the right data, which can impact their productivity and effectiveness.
Lack of real-time data processing: Data lakes are designed for batch processing, and as such, they may not be suitable for real-time data processing. If you need to analyze and act on data as it flows in, you may need to supplement the data lake with other data processing technologies.
Security concerns: As data lakes are designed to store large amounts of data, they can become vulnerable to security breaches. Ensuring that the data is secure from unauthorized access, hacking, or data leaks requires a comprehensive security framework, including data encryption and access control.
As businesses increasingly rely on data to make informed decisions, the need for robust data management platforms has become essential. Traditional data warehouses have their limitations, making it challenging to scale up, be agile, and cost-effective.
However, with the introduction of data lakehouses, businesses can have the best of both worlds. In this blog, we will explore how data lakehouses are improving on the limitations of traditional data warehouses.
One of the significant challenges with traditional data warehouses is their scalability. As data grows exponentially, it becomes increasingly challenging to store, process, and retrieve the data efficiently. This results in longer query times, which slows down the business processes.
With a data lakehouse, businesses can leverage cloud-based storage and computing power to scale up quickly and cost-effectively. With cloud-based data storage and computing, businesses can expand or shrink their storage and computing resources based on demand, making it a scalable and cost-effective solution.
Businesses today require agility to adapt quickly to the ever-changing market demands. Traditional data warehouses take a long time to set up, implement, and modify, resulting in longer lead times for new initiatives. With data lakehouses, businesses can quickly set up, integrate, and modify data pipelines.
This enables businesses to stay agile and adapt quickly to changing market demands. Additionally, with data lakehouses, businesses can store raw data and transform it on-the-fly, enabling businesses to access, analyze, and act on real-time data.
Data warehousing can be expensive, both in terms of hardware, software, and human resources. With traditional data warehousing, businesses often have to invest in expensive hardware and software licenses upfront. Additionally, businesses need skilled professionals to manage and maintain these systems, which can add up to the total cost of ownership.
Data lakehouses, on the other hand, offer businesses a cost-effective alternative. With cloud-based data storage and computing, businesses can pay for what they use, making it a more cost-effective solution. Additionally, businesses can store raw data, eliminating the need for expensive ETL (Extract, Transform, Load) processes.
A Data Lakehouse architecture is built on three key components:
Data Storage: The data storage layer is the foundation of the Data Lakehouse architecture. It is used to store large volumes of raw data from various sources such as log files, sensors, and social media. This data is stored in its native format without being transformed, making it easier to access and query.
Data Processing: The data processing layer is responsible for processing and transforming data into a format that is suitable for analytics. This layer can use various tools and technologies such as Apache Spark, Apache Flink, and Apache Beam to process the data.
Analytics Layer: The analytics layer is the top layer of the Data Lakehouse architecture. It is responsible for providing fast and cost-effective access to data for both batch and real-time analytics. This layer can use tools and technologies such as Apache Druid, Apache Kylin, and Apache Hive to provide fast and efficient analytics.
Overall, the Data Lakehouse architecture provides a unified platform for storing, processing, and analyzing large volumes of data from various sources. This architecture enables organizations to turn data into actionable insights and make data-driven decisions faster and more cost-effectively.
