In 2014, Meta (then Facebook) made waves by acquiring WhatsApp for $19 billion—a deal that brought billions of users into its fold and cemented its position as a mobile-first communications leader. Now, more than a decade later, Meta is making another consequential move—one that could prove even more transformative in the long run. The company’s decision to invest $14.3 billion in Scale AI and bring its 28-year-old CEO, Alexandr Wang, in-house to lead a new “superintelligence” team is a calculated attempt to dominate the next frontier: large language models (LLMs).
While WhatsApp gave Meta user reach and data scale, its latest AI-centric bet positions the company to control the cognitive layer of the internet. If successful, this could define the next era of computing, making the WhatsApp acquisition look relatively narrow by comparison.
Owning the Intelligence Layer
LLMs are becoming the foundation for a new kind of digital infrastructure. From productivity tools and coding assistants to creative platforms and enterprise automation, these models are quickly evolving from experimental novelties to mission-critical systems. The company that controls the development, fine-tuning, and deployment of frontier models will not only gain a competitive edge but potentially define the standards for how human-AI interaction unfolds.
Meta’s investment in Scale AI is a significant step in this direction. Scale is not just a data-labeling company; it is a strategic asset in the AI supply chain, playing a vital role in preparing high-quality, domain-specific data for training models. By bringing Scale’s infrastructure under its roof, Meta is effectively shortening the cycle time between research, training, and deployment, allowing it to iterate faster than competitors.
Just as WhatsApp gave Meta access to communication networks, Scale AI could give Meta access to the very neurons of digital intelligence.
Platform Leverage Over Network Effects
WhatsApp delivered powerful network effects. But LLMs provide something even more valuable: platform leverage. They are not tied to a single use case or platform but can scale horizontally across multiple products, industries, and user personas.
Meta is clearly envisioning a future where its proprietary models—such as Llama 4 and the long-rumored “Behemoth”—power not just chatbots but the entire backend intelligence layer of Facebook, Instagram, WhatsApp, Quest, and enterprise solutions. With Alexandr Wang now steering its AI strategy, Meta is aiming to build a vertically integrated LLM stack: from data sourcing and annotation to compute infrastructure and global deployment.
This approach not only enhances model quality but opens new monetization avenues, ranging from developer APIs to enterprise licensing and AI-powered ads. In contrast, WhatsApp, even with its massive user base, has offered limited monetization potential outside of business messaging and payments.
The Wang Effect: Execution at Scale
Alexandr Wang is not a traditional AI researcher. His strengths lie in operational excellence, fast-paced scaling, and enterprise-grade execution. This reflects a strategic shift within Meta: the LLM race will not be won by research alone, but by translating innovation into productized intelligence at a global scale.
Wang’s presence brings a startup mentality to Meta’s AI efforts—something that could serve as a counterbalance to the more academic or research-centric cultures seen in traditional AI labs. Moreover, Meta’s willingness to offer \$100 million+ compensation packages to lure top AI talent signals that it is willing to outspend, outbuild, and outmaneuver its competitors.
If Meta can successfully bring together the best minds in LLM development, pair them with an optimized data and compute pipeline, and integrate these efforts across its user platforms, it will have built not just a model, but a moat.
From Utility to Ubiquity
WhatsApp’s value lies inits communication utility. But Meta’s LLM strategy targets ubiquity. A successful model doesn’t merely assist users; it becomes embedded in every touchpoint—from auto-generated content and smart recommendations to real-time translation, synthetic media, and developer ecosystems.
This positions Meta to become more than a platform—it becomes the AI operating system of the web. And as AI systems become the gateway for accessing knowledge, creativity, and commerce, Meta could control the lens through which billions of people engage with the digital world.
Final Thoughts
Meta’s WhatsApp acquisition was a watershed moment in mobile technology. But the move to hire Alexandr Wang and double down on large language models could be far more consequential. It is an audacious bet—one with considerable risks, including fierce competition from OpenAI, Google, and Anthropic. Yet, if Meta can execute at scale, deliver competitive models, and fully leverage its ecosystem, it will not just participate in the LLM race—it may define the rules of the game.
In doing so, Meta may achieve something even WhatsApp could not offer: cognitive infrastructure ownership at a global level.

Its popularity speaks for itself, as it has been around for more than 35 years.
According to Google Trends, the above graph demonstrates interest in the term “PostgreSQL” over the past five years. Summarizing the content of this graph, it can be concluded that interest in Postgres has been consistent over the past few years.
This article will explain PostgreSQL, its features, advantages, limitations, and the basic operations that you can perform to manage data.
What Is PostgreSQL?
PostgreSQL, or Postgres, is an open-source object-relational database management system (ORDBMS) that enables you to store data in tabular format. Compared to traditional database management systems, it offers the robustness of object-oriented programming with features such as table inheritance and function overloading.
PostgreSQL: Key Features
Fault Tolerance: PostgreSQL is a highly fault-tolerant RDBMS. With write-ahead logging (WAL), you can track and log your transactional data. During server failure, WAL can be replayed to roll back the operations to the point of the last committed transaction.
ACID Compliance: ACID stands for Atomicity, Consistency, Isolation, and Durability. Postgres offers high reliability by being ACID-compliant. It maintains data accuracy by eliminating incomplete transactions.
Support for Vector Storage: An extension of PostgreSQL, pgvector, allows you to store, query, and index vector data. Using this extension, you can perform extensive vector operations, like similarity search, on your data.
Custom Data Types: Along with pre-built PostgreSQL data types, you can define custom data types, which give flexible data structures that cater to specific applications.
JSON Compatibility: PostgreSQL supports JSON data types, bridging the gap between SQL and NoSQL databases, allowing you to handle semi-structured data effectively.
Table Inheritance: In PostgreSQL, one table can inherit properties from another with the help of table inheritance. This enables you to reuse the previously defined table structure and create hierarchical relationships between tables within a database.
PostgreSQL Architecture
PostgreSQL uses a client/server architecture model where a single session consists of the following operations:
The server process manages database files. It accepts connection requests sent by the client application and executes actions based on the commands provided.
The client application, or the front end, provides you with a way to interact with the Postgres server. There are different forms of client application. It can be a graphical tool, a text-oriented platform, or a specialized database management tool.
Like other client-server applications, the PostgreSQL client and server can be located on separate independent hosts and communicate over a TCP/IP connection. This implies that the file system on different layers of the Postgres architecture may differ significantly. Certain files might only be accessible on the client’s machine.
PostgreSQL forks, or starts, a new process for each connection to enable the management of concurrent requests. With this approach, the client and a new server can communicate without any disruption from the original server. While the client application interacts with a different server, the original service continues, waiting for a new connection.
Let’s learn about the most essential components of PostgreSQL architecture:
Shared Memory: It is the reserved memory of the Postgres architecture, which encompasses two elements: shared buffer and WAL buffer.
The shared buffer is crucial to minimizing disk IO, which depends on three conditions:
When you must access a large number of buffers quickly.
Minimize contention during concurrent access.
Store frequently used blocks in buffers for as long as possible.
The WAL buffer, on the other hand, is a temporary storage space that holds changes in the database. It contains backup and recovery data in the form of WAL files.
Postmaster Daemon Process:
The Postmaster process is the initial method executed when a Postgres instance starts. It performs recovery, initializes shared memory, and runs background checks. Whenever a new client process makes a connection request, the Postmaster process manages the backend service.
Backend Process: The backend process is responsible for performing query requests and transmitting the results. It uses the local memory to execute the provided queries. This memory has different key parameters, including work_mem, maintenance_work_mem, and temp_buffers. These parameters allocate space to store data about a wide variety of operations.
Client Process: Every time you interact with the Postgres server, a new client process is created to handle the connection between the client application and the server. The Postmaster process forks a client process that manages the specific user’s requests.
Basic PostgreSQL Operations
Let’s perform basic create, read, update, and delete (CRUD) operations in Postgres. Before executing the CRUD operations, it is essential to create a database and a table that can store the data.
First, you can execute the PostgreSQL CREATE DATABASE statement.
To create a database named test, open up psql command shell and execute the command below:
CREATE DATABASE test;
You can now select this database and create a table storing all your data. Execute:
\c test;
Let’s create a test_table inside this database using the PostgreSQL CREATE TABLE statement. Replace the column with your preferred column names, mention their datatypes, and run the following code:
CREATE TABLE test_table(
column1 datatype,
column2 datatype,
column3 datatype,
.....
columnN datatype,
PRIMARY KEY(one or more columns)
);
Create Data Record
After creating a table, you can perform the CRUD operations on this table. To insert data into the table, use the INSERT INTO command. Replace the values with different transactional row data and execute the following code:
INSERT INTO test_table
VALUES (value1, value2, value3, ___ valueN);
Running the above code will add multiple rows to your test_table.
Read Data Record
To read the record that you just stored in the test_table, you can use the SELECT statement. Run this code:
SELECT *
FROM test_table;
Instead of using *, which prints out the whole dataset, you can specify the names of the columns you wish to check. For example, you can also use:
SELECT
column1
column2,
----
columnN
FROM test_table;
Update Data Record
If any row does not meet the business requirements and you want to update the row’s specific values, use the UPDATE statement. By specifying a condition under the WHERE clause, you can update the records of rows depending on certain conditions.
UPDATE test_table
SET
column1 = value1,
column2 = value2,
----
columnN = valueN
WHERE
condition;
Delete Data Record
You might find multiple inaccuracies when working with real-world data. Although, for some cases, you can update the values, others might require you to remove the rows from the table directly. To perform the delete operation, you can use the DELETE command as follows:
DELETE FROM test_table
WHERE [condition];
This code will delete the table records that comply with certain conditions that are not required.
What Differentiates PostgreSQL from Other Relational Databases?
Now that you have a thorough understanding of PostgreSQL, how it works, and a few basic operations, let’s explore how it differs from other RDBMS.
The ODBMS functionality of PostgreSQL is the key differentiating factor that shapes its ability to manage complex operations. With the object-oriented approach, you can communicate with databases using objects, define custom data types, and define inheritance—parent-child relationships—between tables.
Compared to other relational databases, PostgreSQL provides more flexibility. Instead of defining logic outside the database, you can model different relationships and data types within a single platform.
Use Cases of PostgreSQL
OLTP Database: PostgreSQL provides online transaction processing (OLTP) capabilities, which is why various financial institutions, startups, manufacturers, and large enterprises use it as a primary data store.
Dynamic Application Development: With PostgreSQL working on the backend of the application, you can develop a robust system to handle complex real-world problems. Utilizing tech stacks like Linux, Apache, PostgreSQL, and Python/PHP/Perl (LAPP) allows the development of dynamic applications.
Geospatial Database: PostgreSQL offers a PostGIS extension that enables you to use and store geographic objects with your relational data. With this extension, you can work with location-based services and geographic information systems (GIS).
Federated Databases: With JSON support and Foreign Data Wrappers, PostgreSQL allows you to interact with data from dispersed locations in various formats. You can use this database as a federated hub for polyglot database systems—an architecture that uses numerous data storage technologies.
Limitations of PostgreSQL
Lack of Horizontal Scalability: PostgreSQL lacks horizontal scalability. You can use it to scale up applications, but scaling out is not supported. Although Postgres has scalability features like sharding, it becomes challenging to manage new database instances, especially if the schema change occurs.
Unplanned Downtimes: Even though PostgreSQL is resilient to outages, it might not be able to handle unexpected events. Events like high web traffic, storms impacting data centers, and cloud provider system outages can cause unplanned downtimes. These circumstances can also affect the failover procedure, causing data inconsistency.
OLAP Limitations: PostgreSQL is a prominent choice for OLTP databases. It also offers some online analytical processing (OLAP) functionality. However, when you use Postgres as an analytics database, its capabilities are limited. To overcome this obstacle, you can use another solution, such as a data warehouse, like Amazon Redshift, with Postgres.
Key Takeaways
PostgreSQL is a popular database that allows you to store and retrieve transactional information. Incorporating this database into your data workflow enables you to manage large volumes of data.
However, with the wide range of features, it is necessary to understand the limitations of using a data storage solution like PostgreSQL. Considering all the advantages and disadvantages enables selecting an RDBMS system that can effectively complement your existing tech stack and business rules.

Among the several available data streaming platforms, Apache Kafka stands out due to its robust architecture and high-performance capabilities.
Let’s explore Apache Kafka in detail, along with its key features, advantages, and disadvantages. Following this, you can use Kafka for diverse applications in domains including finance, telecommunications, and e-commerce.
What Is Apache Kafka?
Apache Kafka is an open-source event-streaming platform that you can use to build well-functioning data pipelines for integration and analytics. With a distributed architecture, Kafka allows you to publish (write), subscribe (read), store, and process streams of events efficiently.
Kafka consists of servers and clients as primary components that interact with each other through TCP network protocol. The servers are spread across several data centers and cloud regions. Some of the servers form a storage layer and are called brokers. On the other hand, clients are software applications that enable you to read, write, and process streams parallelly.
The client applications that allow you to publish (write) events to Kafka are called producers. Conversely, the client applications with which you can subscribe (read) to events are called consumers. The producers and consumers are decoupled from each other, facilitating efficiency and high scalability.
To help you store all the streams of events, Kafka offers a folder-like system called topics. Each topic consists of multiple producers and consumers. Every event that you read or write in Kafka contains a key, value, timestamp, and optional metadata header.
The primary use of Kafka is for event streaming. It is a technique of capturing data in real-time from various sources, including databases, sensors, IoT devices, and websites. You can then manipulate and process these events to load them to suitable destinations. Event streaming finds its usage in different industries, such as finance for payment processing or the healthcare industry for real-time patient monitoring.
Key Features of Apache Kafka
To understand how Kafka works, you should know about its prominent features. Some of these key features are as follows:
Distributed Architecture
Kafka has distributed architecture with clusters as a primary component. Within each cluster, there are multiple brokers that enable you to store and process event streams. To ingest data in Kafka, you can start by publishing events to the topic using producers. Each topic is partitioned across different Kafka brokers. The newly published event is added to one of the topic’s partitions. Events with identical keys are added to the same partition.
In a broker, you can store data temporarily, and then consumers can read or retrieve data from the broker. It is this distributed working environment that makes Kafka a fault-tolerant and reliable data streaming solution.
Kafka Connect
Kafka Connect is a component of Apache Kafka that helps you integrate Kafka with other data systems. The source connector offered by Kafka Connect facilitates the ingestion of data as streams into Kafka topics. After this, you can use sink connectors to transfer data from Kafka topics to data systems such as Elasticsearch or Hadoop. Such capabilities of Kafka Connect allow you to build reliable data pipelines.
Data Replication
In Kafka, as every topic is replicated across multiple brokers, your data is also copied across these brokers. This prevents data loss, ensuring durability. The number of copies of partitions within topics that appear on different brokers is known as the replication factor. It is considered that a replication factor of three is most suitable as it creates three copies, increasing fault tolerance. If the replication factor is one, you will have only one copy, which can be utilized in testing or development, leading to data loss.
Scalability
You can scale Kafka clusters horizontally by adding more broker nodes to distribute growing data volumes. In addition, the partitioning feature supports parallel data processing, enabling efficient management of high data load. For vertical scaling in Kafka, you can increase hardware resources such as CPU and memory. You can opt for horizontal or vertical scaling depending on your requirements to utilize Kafka for complex and high-performance applications.
Multi-Language Support
Kafka supports client applications written in different programming languages, including Java, Scala, Python, and C/C++. Such multi-language compatibility can help you develop data pipelines using Kafka in a computational language of your choice.
Low Latency
You can perform low-latency operations using Kafka due to its support for partitioning, batching, and compression methods. In the batching process, you can read and write data in chunks, which reduces latency. The batching of data within the same partition facilitates compression, leading to faster data delivery. To compress data, you need to use various compression algorithms, including lz4 or snappy.

The BBC Archives Technology and Services team required a modern solution to merge, digitize, and preserve its historical archives for future use.
The team started using Amazon S3 Glacier Instant Retrieval, an archive storage class. They consolidated archives into S3’s cost-effective storage option for rarely accessed historical data. This enabled near-instant data retrieval within milliseconds. By transferring archives to the AWS cloud, BBC also freed up previously occupied physical infrastructure space, optimizing preservation and accessibility.
