Cloud-native applications are designed to fully leverage cloud computing frameworks and environments. These applications are typically composed of distributed microservices, each responsible for a distinct business function. Instead of building a single, monolithic application, cloud-native architecture decomposes functionality into smaller, manageable, and independently deployable services. Microservices communicate with each other over the network, enabling faster development cycles, better scalability, and more robust fault tolerance. These applications are designed to run in containerized environments, which package the code and dependencies together for consistent deployment across different infrastructure setups. The Role of…

Many users have experienced software that is frustrating to use due to persistent issues or bugs. This frustration is often a consequence of the traditional software development approach, where development and operations teams work separately. Developers focus solely on creating the product, while operations handle deployment and maintenance afterward. This siloed approach can result in communication gaps, longer production cycles, and unstable software releases. The Origin of DevOps DevOps emerged as a solution to these challenges. It is designed to bridge the gap between development (Dev) and operations (Ops) teams…

There is an ongoing discussion within the DevOps community about two of the most popular tools for provisioning and configuration management: Terraform and Ansible. As DevOps continues to be a dominant methodology in application development, selecting the right tools is crucial for developers and IT teams. Additionally, the increasing adoption of Infrastructure as Code (IaC) has added complexity and urgency to these decisions. This discussion aims to clarify the differences between Terraform and Ansible, outline when each tool should or should not be used, and ultimately provide a clear understanding…

Containerization is a modern technology approach that packages applications and their dependencies into isolated units called containers. These containers allow software to run consistently across different computing environments. Unlike traditional virtualization, which requires running multiple operating systems on a single hardware platform, containers share the host system’s operating system kernel but keep the applications separated. This ensures that applications are portable, scalable, and efficient. Containerization simplifies the development, deployment, and management of applications by bundling everything needed to run the software, including code, runtime, libraries, and system tools, into a…

Ansible is an open-source IT automation tool that simplifies complex tasks such as configuration management, application deployment, and task automation. Developed by Red Hat, Ansible is agentless, meaning it does not require any software to be installed on the target systems it manages. Instead, it uses Secure Shell (SSH) or Windows Remote Management (WinRM) to execute automation scripts known as playbooks. Key Features of Ansible Ansible is widely adopted due to its simplicity and flexibility. It uses a human-readable language called YAML (Yet Another Markup Language) for its playbooks. This…
