Microservices architecture achieves agility by breaking down applications into smaller, independent services that can be developed, deployed, and scaled individually. This modular approach enables teams to work simultaneously on different components, accelerating the development lifecycle and promoting faster iterations. With microservices, updates and enhancements can be made without disrupting the entire system, allowing organizations to respond swiftly to changing market demands. This architecture enhances flexibility, resilience, and scalability, fostering a more adaptive technological landscape.
