Monoliths and Microservices

The document provides an overview of microservices architecture including: - Definitions and characteristics of microservices such as componentization via services, decentralized governance, and infrastructure automation. - Common drivers for adopting microservices like agility, safety, and scalability. - Guidelines for decomposing monolithic applications into microservices based on business capabilities and domain-driven design. - Discussion of differences between microservices and service-oriented architecture (SOA). - Ecosystem of tools involved in microservices including development frameworks, APIs, databases, containers, and service meshes. - Common design patterns and anti-patterns when developing microservices.

This presentation is conducted on 14th Sept in Limerick DotNet User Group. (https://www.meetup.com/preview/Limerick-DotNet/events/xskpdnywmbsb) SlideShare Url: https://www.slideshare.net/lalitkale/introduction-to-microservices-80583928 In this presentation, new architectural style - Microservices and it's emergence is discussed. We will also briefly touch base on what are not microservices, Conway's law and organization design, Principles of microservices and service discovery mechanism and why it is necessary for microservices implementation.

Microservices are an architectural style that structures an application as a collection of small, independent services that communicate with each other. Each service runs a unique process and focuses on doing a small job, such as user authentication or shopping cart functionality. The advantages of microservices include improved scalability, maintainability, and ability to upgrade parts of the system independently. However, adopting microservices also introduces additional operational complexity and communication overhead between services.

The document discusses microservice architecture, including concepts, benefits, principles, and challenges. Microservices are an architectural style that structures an application as a collection of small, independent services that communicate with each other, often using RESTful API's. The approach aims to overcome limitations of monolithic architectures like scalability and allow for independent deployments. The key principles include organizing services around business domains, automating processes, and designing services to be independently deployable.

Microservices are a new approach to software development where applications are built as a set of independent services that communicate with each other via APIs. This contrasts with a traditional monolithic architecture, where all application components are bundled together into a single program. Some benefits of microservices include increased modularity, scalability, and agility. However, monolithic architectures still have advantages like easier development and better performance. Ultimately, whether a monolithic or microservices approach is best depends on the specific needs and goals of the application.

This document provides an introduction to microservices. It begins by outlining the challenges of monolithic architecture such as long build/release cycles and difficulty scaling. It then introduces microservices as a way to decompose monolithic applications into independently deployable services. Key benefits of microservices include improved agility, scalability, and innovation. The document discusses microservice design principles like communicating over APIs, using the right tools for each service, securing services, and being a good citizen in the ecosystem. It provides examples of how to implement a restaurant microservice using AWS services like API Gateway, Lambda, DynamoDB and containers.

Microservice architecture. Short intro into the world of microservices, the talk I gave in VilniusPHP meetup.

This document provides an overview of microservices architecture, including concepts, characteristics, infrastructure patterns, and software design patterns relevant to microservices. It discusses when microservices should be used versus monolithic architectures, considerations for sizing microservices, and examples of pioneers in microservices implementation like Netflix and Spotify. The document also covers domain-driven design concepts like bounded context that are useful for decomposing monolithic applications into microservices.

- Microservices advocate creating a system from small, isolated services that each own their data and are independently scalable and resilient. They are inspired by biological cells that are small, single-purpose, and work together through messaging. - The system is divided using a divide and conquer approach, decomposing it into discrete subsystems that communicate over well-defined protocols. Each microservice focuses on a single business capability and owns its own data and behavior. - Microservices communicate asynchronously through APIs and events to maintain independence and isolation, which enables continuous delivery, failure resilience, and independent scaling of each service.

This is a small introduction to microservices. you can find the differences between microservices and monolithic applications. You will find the pros and cons of microservices. you will also find the challenges (Business/ technical) that you may face while implementing microservices.

- Microservices architecture breaks applications into small, independent services that focus on specific tasks and communicate over well-defined interfaces. This improves scalability, flexibility and allows for independent development and deployment of services. - The architecture promotes separating concerns, with each small service handling a single "verb" of the application and teams owning service groups. Services are stateless and communicate asynchronously over lightweight protocols. - Automating deployment through containerization allows for easy rollout of new versions with zero downtime and elastic scaling of services based on demand. Monitoring provides visibility into technical and business metrics of the distributed system.
