Why Golang

History 

Go, also known as Golang, is a programming language developed at Google in 2009 by Robert Griesemer, Rob Pike, and Ken Thompson. 

It was designed to be a high-performance language that would be easy to use and maintain, with support for concurrency and garbage collection.

Go was influenced by several other programming languages, including C, C++, and Pascal. 

It has a syntax that is similar to C, but with some additional features that make it more modern and easier to use.

One of the main goals of Go was to improve upon some of the shortcomings of existing programming languages, such as the slow compilation times and complex build processes of languages like C++. 

Go was designed to be easy to build and deploy, with a simple, straightforward syntax that is easy to read and write.

How Different from other languages

Go is a general-purpose programming language that is designed to be simple, efficient, and easy to use. 

It is different from other languages in a number of ways:

Concurrency: Go has built-in support for concurrent programming, with a lightweight concurrency model that uses goroutines and channels to enable multiple processes to run simultaneously.

Memory management: Go has a garbage collector that automatically manages memory allocation and deallocation, which helps to reduce the risk of memory leaks and other types of errors.

Compilation: Go has a fast compilation time, which makes it easier to build and deploy code quickly.

Syntax: Go has a syntax that is similar to C, but with some additional features that make it more modern and easier to use. 

It is known for being easy to read and write, with a clear and straightforward structure.

Standard library: Go has a comprehensive standard library that includes a wide range of packages and functions for a variety of tasks, such as networking, concurrency, and data manipulation.

Where use mostly

It is particularly well-suited for building web servers, command-line tools, and other types of software that require high performance and concurrency.

Go is often used in the development of large-scale systems at companies such as Google, Netflix, and Dropbox, where it is valued for its efficiency and ability to handle high levels of traffic. 

It is also used in the development of distributed systems, microservices, and other types of software that require reliable, scalable performance.

Go is also popular among developers working on cloud-based applications, as it is well-suited for building software that runs on multiple servers and is easy to deploy and scale.

Overall, Go is used in a wide range of applications and industries, 

including software development, finance, healthcare, and more. 

It is a versatile language that is well-suited for building efficient, high-performance software.

Real time examples and applications

Docker: Docker is a popular containerization platform that allows developers to package and deploy applications in lightweight containers. 

Docker is written in Go and uses Go to provide efficient, lightweight containers that are easy to build and deploy.

Kubernetes: Kubernetes is an open-source container orchestration system that is used to manage and deploy containerized applications at scale. 

It is written in Go and uses Go to provide a powerful, scalable platform for managing and deploying containerized applications.

Terraform: Terraform is a popular infrastructure as code (IaC) tool that is used to automate the deployment and management of cloud infrastructure. 

It is written in Go and uses Go to provide a fast, efficient platform for building and managing cloud infrastructure.

etcd: etcd is a distributed key-value store that is used to provide consistent, reliable storage for distributed systems. 

It is written in Go and uses Go to provide a scalable, high-performance platform for storing and retrieving data.

InfluxDB: InfluxDB is an open-source time series database that is used to store and query large amounts of time-series data. 

It is written in Go and uses Go to provide a fast, efficient platform for storing and querying time-series data.

These are just a few examples of the many real-world applications and systems that have been built using Go. Go is a versatile language that is well-suited for building efficient, high-performance software for a wide range of applications and industries.
