Do you know? By the end of next year, 2025, it is expected that the global data size can increase upto 181 zettabytes. That is 181 followed by 21 0’s bytes.
Another fact is that, according to Rivery’s analysis reveals that a staggering 90% of the world’s data was created in just the past two years, with stored data doubling approximately every four years.
So, data is undeniably getting bigger and has become an important asset in the business world.
This means that every business needs to find a scalable, reliable, and faster way to accommodate and process the mind-boggling volume of data. And also the need to address the elephant in the room, real-time data analysis.
The solution? Data Warehouse Modernization.
In the upcoming sections, we will talk about how important data warehouse modernization is for a business, its architecture, and how it can solve the inability of its predecessor, the traditional data warehouse.
Feel free to jump to any section to learn more about how to modernize the data warehouse!
The Growing Data Challenge – Why Traditional Data Warehouses Aren't Enough
Data is getting bigger and unstructured daily. Traditional Data warehouses typically excel in structured data and even perform traditional data analysis, but they struggle to accommodate the diverse format and the source of unstructured information.
Nearly 43% of IT decision-makers worldwide are concerned that their existing infrastructure won't be equipped to handle future data demands.
It can take a significant amount of resources to scale the existing traditional data warehouse and even if the business is ready to partake, there is a high probability of performance bottlenecks and analysis capabilities.
Moreover, the data quality and the security pose as one of the major challenges that traditional data warehouses may not be equipped enough to deal with.
The next evolution of the data warehouse is no longer optional; it’s a necessity.
But, What is Data Warehouse Modernization?
Data warehouse modernization refers to improving and changing how the traditional data warehouse is built to solve today’s data issues as well as modern businesses. This is done by means of a radical revision of the architecture itself, shifting from on-premise systems to much more flexible, scalable, and cloud computing systems.
Key Difference Between Traditional and Modern Data Warehouse
| Differentiation Factor | Traditional Data Warehouse | Modern Data Warehouse |
|---|---|---|
| Infrastructure | On-premise servers and hardware | Cloud-based, flexible, scalable |
| Data Processing | Batch processing, periodic updates | Real-time or near-real-time processing |
| Scalability | Manual, hardware-dependent | Automatic, cloud-enabled scalability |
| Data Model | Rigid, fixed schemas | Flexible, dynamic schemas |
| Data Integration | Slow ETL process | Fast ELT, seamless integration |
| Analytics | Limited to historical data | Advanced analytics, AI integration |
| Maintenance | Ongoing manual updates and maintenance | Managed by the cloud provider, with minimal downtime |
| Cost | High upfront costs for infrastructure | Pay-as-you-go pricing |
How Data Warehouse Modernization Works – Key Components
Before knowing the key components of a Modern data warehouse (MDW), it is important to understand a couple of terminologies, data lakes, and schema.
Data lakes and data warehouses may both store data, but they serve completely different purposes. Think of a data lake as a massive storage pool where all kinds of data—raw, and unstructured can flow in freely. In contrast, a data warehouse is more like a well-organized library, holding cleaned, structured data that's ready for analysis.
Another important element to consider is the schema. Simply put, a schema is like a blueprint that explains how your data is organized, stored, and connected. In data warehouses, schemas are essential for keeping everything in order and making sure data can be accessed quickly and efficiently when you need it.
There are a handful of schemas such as stars, snowflakes, facts, and galaxies and it varies depending on the business requirement and data models.
The next evolution of the data warehouse is no longer optional; it’s a necessity.
MDW works with four major stages:
- Stage #1 – Ingest – Data from various sources is ingested and persisted (stored) in a data lake.
- Stage #2 – Transform – Data validation and transformation to a schema.
- Stage #3 – Data Modeling – Optimizing data for consumption.
- Stage #4 – Serve – Data is exposed with visualization and analysis for the end user.
Key Components are:
- Storage – Storing all raw data from diverse sources, commonly data lakes.
- Compute – Framework for managing to ingest, transform, and serve.
- Orchestrator – Ensures seamless end-to-end coordination and automation of the entire data pipeline, managing workflows and dependencies efficiently.
- Security – Application, platform, and data security.
- Data governance – Guarantees that datasets are managed and organized alongside their recorded lineage.
- Operation (DevOps) – Effective management of the data system, encompassing CI/CD, automated testing, and oversight.
