Linux in the Cloud: Exploring Linux-based Cloud Computing Solutions

Cloud computing has significantly changed the business landscape as various organizations have benefited from the ability to harness scalable infrastructure, flexible storage, and high performance.

At the core of this change is Linux, an open-source operating system that is now the foundation of nearly every cloud computing platform. Due to its flexibility, security, and performance, Linux has gained significant popularity as an operating system in data centers. As businesses have slowly shifted to cloud computing, the demand for Linux will also rise. 

In this article, we’ll focus on using Linux in cloud computing, some of the powerful Linux cloud platforms today, and why Linux is advantageous for businesses in cloud computing. We will also discuss how solutions based on the Linux cloud can minimize software development costs and maximize business performance.

The Rise of Linux in Cloud Computing

Linux is, more or less, the foundation of cloud computing because of its open-source policy, flexibility, and scalability. When companies started moving towards cloud environments, Linux became optimal for operating large-scale distributed environments. 

A major driver of this growth has been the versatility of hardware on which Linux can operate, which is essential for virtualized environments that rely on cloud platforms. Furthermore, Linux's structure is quite simple, and its community is large, so the system is updated regularly, and new security patches are always available. 

This has placed Linux as the favored operating system for cloud platforms, thus fueling the expansion of cloud services. Currently, most of the cloud infrastructure, whether virtual machines or containers, runs on Linux, making the role of Linux in cloud computing clear.

Why Is Linux Dominating Cloud Computing?

The benefits of Linux in cloud computing cannot be overstated. Here are some key reasons why Linux has become integral to cloud computing.

Open Source and Costs

Since Linux is an open-source operating system, businesses can implement cloud solutions while avoiding expensive license costs related to proprietary operating systems. This significantly lowers the cost of mobile app and software development, making cloud solutions affordable for startups and large enterprises. Open source also implies continuous development because developers worldwide update the Linux kernel and related software.

Stability and Reliability

Linux is well-known for its stability and reliability, especially for large-scale and business-critical applications. In cloud computing scenarios where availability and performance are crucial issues, Linux has a reliable and solid structure capable of providing very low downtimes and high performance, even when the loads are very high.

Security Features

Security is a significant issue in cloud computing, and Linux has integral firewalls, strong user authentication, and secure booting. Most cloud service providers in the United States also provide Linux distributions with a special focus on security, known as Red Hat Enterprise Linux and Ubuntu LTS.

Scalability and Flexibility

Small-scale and well-designed, Linux can smoothly be installed and run in any environment, from a virtual machine to a container. This is critical for organizations that need elastic cloud services to address dynamic business needs and application demands.

Support for Containers and Microservices

The use of containers and microservices is currently revolutionizing how applications are developed and hosted in the cloud. Linux has emerged as the leading platform for container applications primarily because of the compatibility of the operating systems with container technologies like Docker. It is particularly relevant for organizations considering cloud microservices adoption as one of their architectural styles.

Automation and DevOps Tools Support

Linux supports automation tools and DevOps, which allows businesses to apply continuous integration and deployment (CI/CD) processes. Most of the automated tools, such as Ansible, Puppet, and Chef, are compatible with Linux to enhance the automation of cloud infrastructures. 

This makes operations smooth, requires minimal human interaction for necessary changes, and shortens the development cycle, enabling businesses to quickly implement changes and new features.

Four Popular Linux-based Cloud Platforms

Several excellent cloud-based platforms are available to Linux users. Our four favorites are as follows:

1. Amazon Web Services (AWS)

AWS continues to dominate the cloud services market, providing numerous services with Linux as the underlying technology. AWS was indeed one of the pioneer cloud platforms that realized the significance of Linux in the cloud for business and integrated Linux-based services as a primary service offering.

Key Linux-based Services on AWS

• Amazon EC2 (Elastic Compute Cloud) is an AWS core service that enables the deployment of virtual servers. Customers can select from Amazon Linux, Ubuntu, CentOS, and Red Hat Enterprise. These virtual machines are quite manageable, as the organization can easily upgrade or downgrade them depending on its needs.
• Amazon ECS (Elastic Container Service): A container orchestration service that lets users schedule and manage Docker containers on a Linux platform. This service benefits organizations that want to grow and deploy their containerized applications.
