![]() This is how the Gossip Protocol brings resilience and efficiency to distributed systems. If it remains unresponsive for a specified duration, it's assumed to have failed. When a node fails to respond, it's initially marked as suspicious. ![]() In the same way, nodes "gossip" about the state of other nodes in the network. Soon, everyone knows that Node A is unresponsive. Those friends, in turn, pass this news along to their circle. If one of them (Node A) stops communicating, another friend (Node B) might notice and start sharing this news with a few other friends (Nodes C, D, E). Speed: Information spreads like wildfire throughout the network due to randomized information sharing. Each node communicates with only a few others, reducing the burden on individual nodes. Robustness: Designed to handle failures, even if one node goes down, the system keeps going strong. Key elements of the Gossip Protocol include: Just recently learned about the Gossip Protocol, an innovative strategy for failure detection in distributive systems! □□ĭespite its name, Gossip Protocol is no idle chatter - it's a powerful communication technique used by nodes in a network to exchange information and efficiently detect failures. #CICD #ContinuousIntegration #ContinuousDelivery #SoftwareDevelopment #CodingBestPractices □□Īdopting CI/CD enhances code quality, speeds up development, and fosters a collaborative environment. This efficient cycle repeats multiple times a day. Simultaneously, Babla pulls Alisha's tested and verified changes and starts working on them. If a test fails, Alisha is notified immediately to fix the issue. The CI/CD pipeline triggers and tests her changes. Alisha pushes her code changes to the repository. □⚡Ĭonsider this scenario: Alisha and Babla are developers on a project. It enhances software quality and speeds up the development process by providing immediate feedback to developers. □□ĬI/CD minimizes 'integration hell', a problem developers encounter when changes aren't integrated frequently and tend to pile up, causing merging issues. □□Ĭontinuous Delivery (CD) ensures that the software can be released at any time by delivering every change to a production-like environment through rigorous automated testing. ![]() Every integration is verified by automated builds and tests. #ObserverPattern #DesignPatterns #SoftwareArchitecture #SoftwareDevelopmentĬasting light on a topic that often baffles many beginner devs - Continuous Integration and Continuous Delivery (CI/CD)! □□ĬI/CD is a critical methodology in the modern software development life cycle, but its nuances can seem daunting to novices.Ĭontinuous Integration (CI) involves merging code changes frequently, ideally several times a day, to catch issues early. It promotes code reusability and modular architecture, making it an essential asset in a developer's toolbox. ![]() The Observer Pattern is a potent tool when you need to communicate state changes to multiple objects without knowing who those objects are. The AuctionItem maintains a list of bidders (Observers) and notifies them when the item's price changes. This code illustrates a simple auction system using the Observer Pattern. Whoever's interested can take a glimpse at how this would look in Java. When the item's price changes, all registered bidders get notified in real-time, ensuring everyone has up-to-date information for a smooth bidding process. Imagine an online auction system where the item (Subject) maintains a list of bidders (Observers). Why use the Observer Pattern? It facilitates real-time notification of state changes and creates a one-to-many dependency between objects, making it ideal for event handling systems, data monitoring, and real-time updates. Observers: Objects that watch the subject and get notified when the subject changes state. This promotes a loose coupling between objects, enhancing flexibility and modularity.ġ. The Observer Pattern is a software design pattern where an object, known as the Subject, maintains a list of dependents, called Observers, and notifies them of any state changes.
