The Evolution of Data Platforms : Beyond Data Lakehouses

April 7, 2025 by Ashwin Leave a Comment

The data platform landscape has undergone multiple transformations over the past decades – from traditional data warehouses to data lakes, and most recently to data lakehouses. Each evolution has addressed the limitations of previous architectures while accommodating new workloads and use cases. As we move into 2025, we’re witnessing the emergence of the next generation of data platforms designed specifically for the AI-driven world.

The Data Platform Journey

Early Days: Data Warehouses

Data warehouses revolutionized business intelligence by providing structured, optimized environments for SQL-based analytics on historical data. While powerful for reporting and dashboarding, they struggled with semi-structured data, real-time processing, and faced scalability challenges.

The Rise of Data Lakes

Data lakes emerged as cost-effective storage solutions that could handle massive volumes of raw, unprocessed data in various formats. They offered unprecedented flexibility but often became “data swamps” lacking governance, quality control, and performance optimization.

The Data Lakehouse Compromise

Data lakehouses represented a hybrid approach, combining the best of both worlds: the structure, transaction support, and performance of warehouses with the flexibility, scalability, and cost-effectiveness of data lakes. Solutions like Databricks’ Delta Lake, Snowflake, and Amazon Redshift Spectrum allowed organizations to manage both structured and unstructured data while supporting diverse workloads.

Beyond Data Lakehouses: The AI-Native Data Platform

As we move forward, data platforms are evolving once again to meet the demands of AI-driven workloads and applications. Here are the key characteristics defining this next generation:

Book review : The Almanack of Naval Ravikant

October 6, 2024 by Ashwin Leave a Comment

Despite my lack of expertise in writing book reviews, I felt compelled to share my thoughts after finishing ‘The Almanack of Naval Ravikant‘ by Eric Jorgenson this weekend.

It is one of those books sprinkled with words of wisdom, without preachiness.

This book reminds me of other wisdom-filled works like Charlie Munger’s ‘Poor Charlie’s Almanack‘ and Clayton Christensen’s ‘How Will You Measure Your Life‘.

Let me be clear – this book is a collection of tweets and other thought nibbles, neatly organized by topics.

But it brings out Ravikant’s wisdom and experience shine through, offering us a fresh perspective on life.

The book is divided into 2 broad categories:

Wealth
Happiness

In the section on wealth, Naval delves into various aspects of financial success, including wealth creation strategies, leveraging resources effectively, choosing the right career path, developing crucial mental models, and honing decision-making skills.

He posits that happiness is a choice available to everyone, and he explores habits that foster joy, as well as methods for personal growth, self-care, and achieving inner freedom.

The book concludes with a philosophical exploration of life’s meaning and the importance of aligning one’s actions with personal values

Allow me to share some of my key takeaways from the book. These highlights only scratch the surface of the wisdom within these pages – I highly recommend grabbing a copy for yourself to fully appreciate its depth and insights!

Learn to sell. Learn to build. If you can do both, you will be unstoppable.
Specific knowledge cannot be taught, but it can be learned.
Intentions don’t matter. Actions do. That’s why being ethical is hard.
If you don’t own a piece of a business, you don’t have a path towards financial freedom.
Earn with your mind, not your time.
Retirement is when you stop sacrificing today for an imaginary tomorrow.
Hard work is really overrated. How hard you work matters a lot less in the modern economy.
You don’t get rich by spending your time to save money. You get rich by saving your time to make money.
“Clear thinker” is a better compliment than “smart.”
What you want is principles. You want mental models.
Read what you love until you love to read.
Happiness is the state when nothing is missing.
First, you know it. Then, you understand it. Then, you can explain it. Then, you can feel it. Finally, you are it.
The greatest superpower is the ability to change yourself.

I dabble around with a lot of books and there are many unfinished ones in my reading list. This book is one of very few I managed to finish in recent times!

Thanks, Naval for sharing your wisdom with all of us! Please keep writing…

Communicate your Software Design better with C4 Model

June 16, 2024 by Ashwin Leave a Comment

As engineers and tech leads, we often underestimate the need for our software design to be understandable.

The simpler the design, the higher its utility and purpose.

The C4 model is one of the popular and proven ways to visually communicate your design to a wide range of audiences. Its beauty is the “drill down” method, making it usable by technical and non-technical audiences.

What is a C4 Model in Software Design?

C4 models are a hierarchical abstraction of software systems, achieved through a set of diagrams. They are designed to be notation and tool-independent, which can be applied to almost all type of systems.

It is an “abstraction-first” model, that reflect how software architects and developers think about building software.

C4 stands for:

System Context
Container
Component
Code

In ascending order of granularity, each of these diagrams gives a more detailed view of the software system that’s being built.

What are the C4 Model Abstractions?

4 levels of abstraction are at the core of a C4 Model.

Software system – the highest level of abstraction of any system that has some utility (e.g., a maps application)
Containers – a software system is made up of one or more containers (e.g., applications, data stores, etc.)
Component – each container is made up of several components (e.g., relational data store, NoSQL data store, etc.)
Code – finally, each component is implemented by software code using a tech stack (e.g., MySQL, DynamoDB, etc.)

Each of these abstractions is represented as C4 diagrams.

C4 Model Diagrams

System Context Diagram

The system is visualized as a single box which is at the center
This diagram shows how the system interacts with its environment and users
Focus is on the people and interacting systems, not on technology or tools
Everyone, irrespective of their technical acumen, must be able to understand this diagram

Container Diagram

A container view represents various applications that constitute the system
This diagram can show the major technology choices and how the containers interact with each other
It is intended for a technical audience, but anyone with a need to know how the system works can use this diagram

Component diagram

In this diagram, the container is decomposed into structural building blocks and their interactions
Each component’s responsibilities, interaction with other components, and technical details are called out here
Software architects and developers are the primary intended audiences
It is not recommended for all teams, so use it only if you think it adds value

Code diagram

Represents how each component is implemented as code – using UML diagrams, ER diagrams, etc.
Usually generated using IDE or UML modeling tools
This level of detail is normally required only for complex components

In summary, C4 diagrams improve the communication efficiency of your software design. The level of detail and type of diagrams is contextual to the system under design.
