We've put together this list of ten popular open-source software examples so that you can find out more details on each one!

OpenStack

(Image Source : OpenStack )

OpenStack is an open-source software platform for building public and private clouds. It provides a number of services, including object storage, virtualization, container orchestration (Kubernetes), Internet of Things (IoT) connectivity, load balancing, and application deployment.

NASA originally developed it in 2009 as a private cloud solution that other organizations could use to run their own cloud infrastructure on top of it. However, in 2015 the OpenStack Foundation was established to manage development efforts across all projects under the organization's umbrella.

OpenStack is primarily used as an Infrastructure as a Service (IaaS) solution, allowing users to build and run their own private cloud infrastructure. However, it can also be used as a Platform as a Service (PaaS), enabling developers to create applications that run on top of OpenStack's cloud platform services.

OpenStack features a dashboard that gives users an overview of their cloud environment and allows them to manage it. It also offers tools for configuring networking, storage, and compute resources in its infrastructure-as-a-service (IaaS) deployment model.

OpenStack is supported by hundreds of companies and organizations around the world, including Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and IBM Bluemix. In addition, more than 70 different companies contribute to the OpenStack code base on a regular basis.

Kubernetes

Kubernetes is an open-source system used to set up, manage and scale containerized applications. It's the de facto standard for deploying and managing containerized workloads at scale.

Google created Kubernetes in 2014 as an open-source project which enables users to deploy applications across multiple machines on a cluster of nodes managed by Kubernetes. The concept behind Kubernetes is simple: you create virtual machines (VMs), create containers inside them, and assign those containers to different VMs based on their workloads or needs. 

The VMs can be Docker containers running in your local machine or zipped-up Linux OS images that contain all their dependencies pre-installed on the box itself along with additional packages we call "pods" - these pods help run multiple instances of services such as databases etc. so that each pod doesn't require its own VM instance which would only serve one VM at once due to resource constraints within our environment example: "I have an application I want to deploy on Kubernetes. How do I do that?"

The answer is simple: use a tool called Compose. This tool allows you to take your application code and dependencies (Dockerfiles, etc.), as well as configuration files (such as environment variables), and create a Kubernetes-ready application JSON file that can be deployed with the following command:

Compose --from-file [your application JSON file] deploy

Compose is a tool that helps you convert your application into Kubernetes objects. It analyzes the contents of your application and generates the appropriate configuration files for deployment in any environment.

Apache Kafka

Apache Kafka is a distributed streaming platform that's used for assembling real-time data channels and streaming applications. It's designed to scale up to thousands of tasks processing events at any given time, which means it can be used for things like real-time analytics, log processing, and even machine learning.

Kafka provides two core components: Kafka Streams is a collection of higher-level abstractions that allow you to easily write programs that take advantage of multiple topics in your cluster; Kafka Connect shows how clients connect directly to different brokers on the same cluster without having direct access to data via MapReduce (which would normally require setting up multiple clusters).

Kafka Connect allows you to connect to external systems, databases, and applications in order to process data in real time. It provides several connectors, essentially plugins, that allow you to connect Kafka Streams directly with other systems.

It also provides a number of connectors that allow you to connect Kafka Streams directly with other systems. Kafka Streams is a collection of higher-level abstractions that allow you to easily write programs that take advantage of multiple topics in your cluster. Kafka Streams has two core components: This allows you to write code that looks like stream processing, but instead of having to worry about all the complexities of distributed systems, it's handled for you automatically.

Apache Spark

Apache Spark is a quick and general engine for vast amounts of data processing. It can handle both structured and unstructured data, supports various programming models, such as functional programming and object-oriented style, and has excellent fault tolerance, scalability, and high performance.

Spark is based on concepts of functional programming, but it also supports other paradigms like graph processing or machine learning algorithms. Because of this flexibility, it can be used as a replacement for Hadoop / MapReduce, which was originally developed by Google in 2004 when they needed to process massive amounts of data quickly but were unable to do so using existing technologies such as MapReduce due to their lack of support for other styles like SQL (Structured Query Language).

Spark can be run on Hadoop or standalone. It is open source and is licensed under the Apache 2 license. Spark is developed by Apache Software Foundation. It was originally written in Scala, but later support for Java, Python, and R was added. It has a high-performance engine called Tungsten which is responsible for distributing computations across multiple computers and managing memory efficiently.

Spark is a general-purpose processing engine that uses in-memory processing to handle large data sets. It is capable of running SQL queries on top of the existing MapReduce framework. Spark can also run machine learning algorithms like PageRank or Recommendation Engines. 

It has a high-performance engine called Tungsten which is responsible for distributing computations across multiple computers and managing memory efficiently.

Hadoop

An open-source software framework for storing and large-scale processing data sets on commodity hardware groups. It was developed to scale up from single servers to hundreds of machines, making it ideal for certain types of large-scale processing. Hadoop's architecture is based on the concept of MapReduce, which enables distributed applications to split their tasks into smaller units and perform them in parallel across multiple nodes (a cluster).

Hadoop is written in Java and runs on the Java virtual machine (JVM). The Hadoop Distributed File System (HDFS) provides scalable high availability by replicating data between multiple nodes in a cluster that have access to each other's disks via network drives or HDFS directories - meaning you can store your files locally. At the same time, they're being processed by another machine in another location!

It supports a variety of applications, from simple workloads such as web indexing to complex analytics like clickstream analysis. In addition, Hadoop provides reliability with its built-in redundancy, fault tolerance, and scalability.

ELK Stack

ELK Stack is a combination of three popular open-source projects - Elasticsearch, Logstash, and Kibana. Elasticsearch is a potent search and analytics engine, Logstash is a data processing pipeline, and Kibana is a visualization tool. Together, these three tools form a powerful logging and data analysis solution. 

It is a powerful search engine that can index and search huge amounts of data in real-time. Logstash is a data processing pipeline that can ingest data from a variety of sources, process it, and then send it to Elasticsearch. Finally, Kibana is a visualization tool that can take data from Elasticsearch and create beautiful visualizations. 

The ELK Stack is a powerful solution for logging and data analysis. If you have a lot of data that you need to be able to search and analyze, then the ELK Stack is worth considering.

React.js

React is a JavaScript library for creating UI. React can be utilized as a base in the development of single-page or mobile applications. However, React is only one of the many tools in the JavaScript ecosystem. Furthermore, react is not a framework; it is a library that focuses on one particular problem: building user interfaces.

We can think of React as the "V" in the MVC pattern. The controller mediates between the model and the view in a traditional MVC application. In a React application, the view is a function of the state. The state is the single source of truth. The view is just a projection of the state. When the state changes, the view is updated automatically.

This is a radical departure from the traditional MVC paradigm. It simplifies the mental model and makes the code more predictable. React is declarative. This means that we can describe the desired output, and React will take care of the rendering.

This makes the code more readable and easier to reason about. React is component-based. This means that we can decompose the UI into independent, reusable pieces. This makes the code more modular and easier to maintain.

React.js is efficient. React uses a virtual DOM diff algorithm to determine the minimum set of changes that need to be made to the DOM. This makes React very fast. In conclusion, React is a JavaScript library for building user interfaces. It is declarative, component-based, and efficient.

Angular.js

Angular.js is a framework for building single-page web applications. It's built using TypeScript and based on MVC (Model View Controller) design pattern, which means that it uses a syntax similar to HTML, CSS and JavaScript for creating web pages.

The benefits of using Angular.js include the following:

• Rapid development times; developers can build applications quickly because they don't need to spend time learning new languages or frameworks.
• Flexibility; developers have full control over the way their code looks without the need for extra tools such as XML files or single-page templates

Node.js

With the powerful, open-source Node.js runtime environment, programmers can run JavaScript code outside of a web browser. It is an event-driven, non-blocking I/O architecture that is optimized for constructing network-based applications that are scalable. This makes it ideal for real-time applications such as web sockets and chat servers. Because of its large module library, Node.js is a flexible and popular programming language for both client-side and server-side applications. There are numerous open-source Node.js-based admin panel software solutions developed to provide a back office for managing data.

GitLab

GitLab is a web-based Git repository manager with wiki, issue tracking, code review and other features. It provides free private repositories for up to 10 users. GitLab can be self-hosted on GitHub or Bitbucket. If you need more than 10 users or if your team is larger than 20 people, then you have 
to pay $5/user/month.

Django

Django is a free and open-source web framework that follows the model-view-template (MVT) architectural pattern and is written in Python language. It aims to ease the development of complicated, database-operated websites.

Django's philosophy is "don't do anything that you don't have to", which means that it tries not to impose any extra work on your build process or codebase. This makes it easy for developers who want to get started quickly with their projects without having to learn how everything works under the hood first.

Open-source software saves money for you, your company and the world

Open-source software is the best option for businesses. It's free, which means you can save money on licensing costs and other associated expenses. It also means that your business will be less likely to have problems with piracy since open-source software is freely available online and does not require a license from its developer.

In addition to being cost-effective for small businesses, open-source software is also beneficial for large corporations looking to improve their productivity or efficiency in various ways (e.g., by allowing employees from different departments or locations access directly). 

Furthermore, companies who use open source can take advantage of community support forums where they can get advice from other users regarding problems they're having while using this type of software—as opposed to proprietary solutions, which only allow one person at any given time access over a network connection (which might not always work properly).

Best free open-source software 

There are many reasons to love open-source software. Most importantly, it allows anyone to collaborate on and improve the software. This means that open-source software is usually more reliable and secure than closed-source software because anyone can find and fix bugs.

Another great reason to use open-source software is that it is usually free. This is a huge advantage over closed-source software, which can be expensive. Not only is open-source software free to use, but you can also usually modify and redistribute it without having to pay anyone.
