A complete guide to full-stack developer interview questions, covering coding expectations, system design depth, DevOps basics, debugging skills, and preparation strategy.

Lean Product Management is a modern methodology that guides a product from idea to launch (and beyond), using frameworks like Lean Startup and continuous discovery. It emphasises rapid, customer-driven iteration, waste reduction, outcome-focused roadmaps, and adapting strategy through product lifecycle stages (from problem–solution fit to scale).

Today, we will be covering how to create an HTTP cookie, HTTP cookie properties, and HTTP cookie types.

Selecting the right architectural pattern is crucial for building robust and scalable systems in today's fast-paced software environment. Service-Oriented Architecture (SOA) and Microservices are two prominent approaches, each with unique advantages. SOA emphasizes centralized governance, reusability, and interoperability, making it suitable for large enterprises. In contrast, Microservices adopt a decentralized model, allowing independent services to communicate via lightweight protocols, promoting agility and rapid deployment. Understanding the distinctions between these architectures is essential for aligning system design with business goals. This blog will compare SOA and Microservices, exploring their key features, development practices, and ideal applications to guide software development decisions.

This blog emphasizes the role of Continuous Integration (CI) and Continuous Deployment (CD) in creating resilient software systems. In today's fast-paced digital environment, CI enables developers to frequently integrate code changes into a shared repository, with automated tests ensuring stability. CD automates the deployment of these changes, allowing for quick releases and minimizing downtime. Resilient systems are characterized by traits such as redundancy, fault tolerance, self-healing, scalability, and adaptability, which help maintain essential functions during disruptions. Companies like Netflix and AWS illustrate how CI/CD practices enhance system resilience. The CI/CD pipeline consists of Continuous Integration, Continuous Deployment, and Continuous Testing, promoting early bug detection and rapid recovery from failures. Integrating CI/CD with resilient system design is essential for building robust software that effectively responds to challenges and user needs.

Fault tolerance is a system's ability to maintain operations despite component failures, crucial for reliability and user trust. Key issues include hardware failures, software bugs, and network problems, emphasizing the need for redundancy to mitigate single points of failure (SPOF). Principles of fault-tolerant design include redundancy, graceful degradation, and failover mechanisms. Tools like cloud platforms and container orchestration are essential for resilience. Best practices involve anticipating failures, regular testing, and clear documentation. Robust fault-tolerant designs are vital for ensuring system reliability and fostering continuous improvement to adapt to evolving challenges.

As systems become more complex, deployment methodologies are essential for facilitating seamless updates and enhancing system resilience. A well-defined deployment strategy ensures high availability and also significantly impacts user experience by reducing downtime and maintaining system stability. By prioritizing deployment strategies, organizations can strike a balance between innovation and reliability, ultimately leading to improved customer satisfaction and business success. This exploration will delve into specific methodologies, including Continuous Integration/Continuous Deployment (CI/CD) and blue-green deployments, highlighting their transformative potential in software delivery and maintenance.
