Networking is vast, and it’s complex and generally horrific. But the actual day‑to‑day stuff with container networking is actually super cool. It’s slick and simple. We’ll dive straight in with the different types of networks Docker supports and then we’ll do network services. Network Types Containers need to talk to each other. Sometimes they even […]

In this page, we’re going to look at a communication style called synchronous communication, which is useful within our microservices architecture. This communication style is basically a pattern of making a request and then waiting for an immediate response. Use Cases Best Practices for Implementation Implementing synchronous communication effectively is crucial to ensure that applications

Load balancers are networking devices or software components that evenly distribute incoming network or application traffic across multiple servers or resources. They play a crucial role in optimizing resource utilization, ensuring high availability, and improving the reliability and performance of modern applications and services by preventing any single server from becoming overwhelmed with traffic. Load
Resiliency design principle of mircroservices is all about making our software reliable and available and ensuring that if we do have any failures within our back‑end microservices, each service fails fast and there’s alternate functionality so that the user doesn’t face any disruption. Let’s discuss the various steps to develop a resilient system Design for

In the Visitor pattern, we employ a visitor class to alter the execution algorithm of an element class. This flexibility allows the element’s execution algorithm to adapt as the visitor changes. This pattern falls under the behavior pattern category. In accordance with this pattern, an element object must accept the visitor object, enabling the visitor
The Template Method is a behavioral design pattern that defines a blueprint for an algorithm in a superclass but allows specific steps of the algorithm to be overridden by subclasses without changing its core structure. Consider developing a data mining application that analyzes corporate documents in various formats (PDF, DOC, CSV) to extract meaningful data.
The State Pattern is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The pattern encapsulates states as separate classes and delegates the state-specific behavior to these classes. This makes it easy to add new states and modify the behavior of an object without altering its structure.
The Mediator pattern, also known as the Intermediary or Controller, helps manage communication between different objects. It stops objects from talking to each other directly and makes them talk only through a mediator. This keeps things more organized and prevents messy connections between objects. In air traffic control systems multiple aircraft need to coordinate their
The Proxy pattern is a structural design pattern that allows an object (the proxy) to act as an intermediary or placeholder for another object, controlling access to it. It is often used to add a level of control or optimization to the interactions with the real object, such as lazy loading, access control, or logging.
An Adapter pattern allows incompatible interfaces to work together, acting as a bridge. It converts the interface of one class into another interface that clients expect, enabling collaboration between classes with differing interfaces. The Adapter Pattern is also known as Wrapper. Imagine you are developing a music streaming application that plays audio files using a new
