 LinkedIn is a social media platform. It is the biggest name in professional
networking. It’s designed for professional community. Since LinkedIn’s inception,
it is mostly used for professional networking, job searching and career
development. It works as a great tool to serve as virtual resumes.

The story of LinkedIn’s creation

Reid Hoffman and a small group of co-founders founded LinkedIn. The founders
observed a need for an online platform that would allow professionals to connect,
share their professional experiences, and grow their professional networks. They
officially founded LinkedIn on December 14, 2002. On May 5, 2003, LinkedIn
was formally launched to the public. Initially, the platform was only open to a
small number of individuals, especially those in the Silicon Valley tech industry.
LinkedIn gradually expanded its user base and services over time. Microsoft
announced its plan to acquire LinkedIn for $26.2 billion in June 2016, making it
one of the largest tech acquisitions at the time. The acquisition was completed in
December 2016, with LinkedIn continuing to operate as an independent
organization within Microsoft. Since its founding, LinkedIn has continued to
expand, introducing services such as content sharing, chat, and online learning
tools. It is still one of the world's largest sites for professional networking, with
millions of users worldwide.

The Technology behind LinkedIn

LinkedIn, began as an online resume database in 2003 and has evolved over time,
using PHP on the front-end and various languages for its various parts. It started
with HTML/CSS and SQL and later added PHP, Java, Ruby, NodeJS, Go and
Javascript. LinkedIn also implemented services like BigQuery, Kubernetes, Redis,
Solr, Kafka, Postgres and Zookeeper.
Java is used by LinkedIn, with the majority of its codebase running natively on top
of Java 11. The platform uses three servers: Elasticsearch, Apache Cassandra, and
MongoDB, all running on Linux operating systems. LinkedIn's backend framework
is mainly NGINX and MariaDB.
Initially built as a free online tool, LinkedIn has grown rapidly, now boasting
nearly 600 million active registered users and 300 billion monthly connections.
With over 500 million members worldwide, LinkedIn continues to help people
build professional relationships and discover potential connections within and
outside their industry.
LinkedIn uses a variety of programming languages, including PHP, HTML, CSS,
Javascript, SQL, OData, XML, JSON, XSLT, ColdFusion, VBScript, Ruby-on-
Rails, Spring Groovy, Framework, Java, Scala, Swift, Dart, Clojure, Objective-C,
Go, Haskell, Prolog, Lisp, Erlang, F#, Bash, Perl, Pascal, COBOL, and Fortran, to
enable faster code development. The front end is developed in React Native,
Angular 2+, and Polymer, while the backend is mostly made up of NodeJS,
Express, MongoDB, Redis, Elasticsearch, AWS Lambda, Cloudfront, S3,
DynamoDB, and Kinesis. LinkedIn processes 1 billion requests per day, processing
around 3 terabytes of traffic daily. The majority of its features revolve around
sharing content, with most services focusing on finding connections.
Notable projects that leverage LinkedIn's API include Pulse, LinkedIn Data
Extractors, LinkedIn Insightly Dashboard, Opinion and Activity Explorer,
LinkedIn Search Engine, LinkedIn Feed Reader, LinkedIn Job Board, and

iOS, and Chrome OS. Its backend consists of components like a message broker,
