In modern distributed systems, components and services often depend on each other to function correctly. The Circuit Breaker pattern is a design pattern that helps protect systems from cascading failures by monitoring the health of a dependent system and, if it detects that the system is failing, it will stop sending requests to that system.
Containers have revolutionized the way we develop and deploy applications, providing a lightweight and portable solution to run applications consistently across different environments. In order to manage resources effectively in these environments, control groups or cgroups come into play. In this blog post, we will delve into the world of cgroups, explore their benefits, and understand how they function to enhance the performance of containerized applications.
UnionFS is a user-space, stackable file system that unifies multiple file systems, presenting them as a single cohesive file system. It plays a crucial role in containerization platforms like Docker, which use UnionFS to optimize storage, simplify backups, and efficiently manage resources. In this blog post, we’ll explore the relationship between UnionFS and Docker, discussing how they work together, providing an overview of the relevant commands in this context, and diving deeper into the specific features and best practices that make UnionFS an indispensable part of the Docker ecosystem.
Docker has profoundly impacted software development and deployment, offering containerization capabilities that simplify application management. The Linux kernel features that support Docker containers create isolated, resource-controlled, and efficient environments for applications. This blog post delves into the essential Linux kernel features at the heart of Docker containers: namespaces, cgroups, and union file systems. We’ll also examine Linux commands that provide insights into these features, giving readers a comprehensive understanding of Docker’s inner workings and the technologies that support it.
Indexing is a powerful technique in relational databases that enhances query performance by minimizing the time it takes to search and retrieve data. It’s similar to the way you use an index in a book to quickly find the page containing the information you seek. In this blog post, we’ll dive into the world of indexing, focusing on how it works in relational databases like PostgreSQL, and explore the benefits and trade-offs involved.
Introduction The Law of Demeter, also known as the Principle of Least Knowledge, is a design guideline in object-oriented programming that encourages objects to communicate only with their immediate neighbors and not with objects further away from the object graph.… Read More »Understanding the Law of Demeter: The Principle of Least Knowledge
Introduction The DRY (Don’t Repeat Yourself) principle is a fundamental programming concept that encourages the reduction of code duplication by extracting common code into reusable functions or modules. Following the DRY principle leads to more maintainable, efficient, and reliable software… Read More »Embracing the DRY Principle: Don’t Repeat Yourself
Introduction The SOLID programming principles are a set of guidelines that, when followed, can lead to clean, maintainable, and efficient code. These principles were introduced by Robert C. Martin and are widely adopted by developers across the world. In this… Read More »Mastering SOLID Principles: A Guide to Clean and Maintainable Code
Introduction As software applications become more intricate, handling their architectural design turns increasingly difficult. A design pattern that has risen to prominence lately is Command Query Responsibility Segregation (CQRS). In this blog post, we will explore the core concepts of… Read More »Achieving scalability using Command Query Responsibility Segregation (CQRS) pattern
