This document provides an introduction to microservices, including a comparison to monolithic architectures. It discusses advantages and disadvantages of both monoliths and microservices. Monoliths have disadvantages including being difficult to change and maintain as well as not scaling well. Microservices aim to address these issues by developing applications as suites of small, independent services. The document outlines some key principles of microservices, such as independent deployment and technology choices, as well as advantages like improved scalability and flexibility.

The document discusses merging microservices architecture with SOA practices. It begins with background on the presenter and an agenda that includes defining and sizing microservices, DevOps practices for deployment, and avoiding fragility. Microservices are defined as small, independent, and process-isolated services. The document explores benefits and challenges of microservices, including proper sizing of services and managing dependencies. It provides examples of DevOps practices for loose coupling like service isolation and separate databases. The conclusion emphasizes starting small and reconciling SOA and microservices when sharing capabilities, APIs, and building applications.

Full lifecycle of a microservice: how to realize a fault-tolerant and reliable architecture and deliver it as a Docker container or in a Cloud environment

Today, every one of us wants to get things done fast. The fact of the matter is Serverless is a fantastic platform for doing things fast. Because, with Serverless, you really don’t have time to waste in terms of delivering your business value. Turns out you can with the right cloud services. In this talk we’ll create a microservice using Azure Functions and also get introduced to bigger picture of serverless computing. I presented this session in Global Azure Bootcamp 2019 in Dublin. #GlobalAzure #AzureFunctions #Serverless

The document discusses characteristics of microservice architectures. It defines microservices as independently deployable services that communicate through lightweight mechanisms like HTTP APIs. Key characteristics include: componentization via services; organization around business capabilities rather than technology; treating services as products with long-term support; decentralized governance, data, and infrastructure; and designing for failure and evolutionary development. The document also compares microservices to monoliths and alternative approaches like self-contained systems.

A introduction to Microservices Architecture: definition, characterstics, framworks, success stories. It contains a demo about implementation of microservices with Spring Boot, Spring cloud an Eureka.

This document summarizes an upcoming presentation on architecting microservices on AWS. The presentation will: - Review microservices architecture and how it differs from monolithic and service-oriented architectures. - Cover key microservices design principles like independent deployment of services that communicate via APIs and using the right tools for each job. - Provide example design patterns for implementing microservices on AWS using services like EC2, ECS, Lambda, API Gateway and more. - Include a demo of microservices on AWS. - Conclude with a question and answer session.

This document discusses an SDLC (Software Development Life Cycle) process for developing microservices. It begins by defining key terms like SDLC, microservices, and APIs. It then outlines a 10-step process for taking a microservice from concept to production, including specifying APIs, prototyping, testing, and reviews. It emphasizes practices like API versioning, testing in production, and treating failures as normal occurrences. The presentation is delivered by David Asher, an experienced software and product manager providing the perspective of developing cloud-based microservices at large companies.

What integration, service, or API infrastructure components are appropriate for my platform? Should teams Decouple at Edge or Center? Why incorporate API Gateways, Enterprise Service Bus (ESB), or integration frameworks into your platform and architecture?

Do microservices force us to look differently at the way we lay down and evolve our integration architecture, or are they purely about how we build applications? Are microservices a new concept, or an evolution of the many ideas that came before them? What is the relationship between microservices and other key initiatives such as APIs, SOA, and Agile. In this session, we will unpick what microservices really are, and indeed what they are not. We will consider whether there is something unique about this particular point time in technology that has enables microservice concepts to take hold. Finally, we will look at if, when, where and how an enterprise can take on the benefits of microservices, and what products and technologies are applicable for that journey.

- 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.

Vertical thinking for a simple architecture! Micro Services are a new way of architectural thinking in web platforms. The key idea is strongly aligned on the unix philosophy: Create small services which are only responsible for one thing and make them work together. With this in mind, you get simple applications, which can be developed, deployed and scaled independent from each other. The key challenge in using micro services is to decompose applications vertically, by their functional domains. Only with this, you are able to reduce dependencies and create simple applications. On a technical side, micro services are backed by a wide support in different programming languages and open source frameworks. Especially the state of the art deployment mechanisms make this approach possible at all.

Microservices at Netflix have evolved over time from a single monolithic application to hundreds of fine-grained services. While this provides benefits like independent delivery, it also introduces complexity and challenges around operations, testing, and availability. Netflix addresses these challenges through tools like Hystrix for fault tolerance, Eureka for service discovery, Ribbon for load balancing, and RxNetty for asynchronous communication between services.

Is Microservices gaining momentum? Looking at the interest in microservices in Australia at the moment, it is evident that this is a Service Oriented Architecture making waves. I shared our insights and experiences to over 500 interested attendees at completely sold out YOW! nights events across Sydney, Brisbane and Melbourne. These talks revealed the core lessons ThoughWorkers have learnt building a variety of systems with Microservices architecture globally. They aimed to help viewers identify Microservices and their counterparts; guide them on where to use Microservices; and deliver a series of practices for technologists to build, test, deploy and operate a Microservices architecture. The world of software architecture is excited and energised with the promises of a new Service Oriented Architecture, Microservices; rapid deployment, scalability, autonomy, and faster cycles of experimentation and innovation, and we are too!

This presentation shows the properties, advantages and challenges of microservices. It then discusses alternative architectures beyond microservices.

The popularity of implementing microservices in today’s application landscape continues to rise, and there have been countless success stories focused on migrating from monoliths to microservices. But as more teams move toward microservices architectures, an increasing number of stories have arisen about the pain of poor choices. Microservices are not the answer to all application problems. Attempts to move away from one giant application to smaller focused services often result in a tightly coupled nest of applications. Blithe Rocher covers some of the pitfalls and lessons learned from building several service-oriented systems. Blithe explores some of the problems with building, testing, and deploying a functional microservice architecture, from data loss to dependency nightmares, drawing on war stories she has collected and from her own personal experience. You’ll come away with some valuable lessons about microservices without having to go through the pain of experiencing them yourself.

Fred George describes his personal journey discovering microservice architecture over 15 years working on large software projects. He details how his projects evolved from monolithic 1 million line applications to small, independent services. This allowed for improved agility, with services being short-lived and able to deploy several times a day. George also discusses challenges faced and lessons learned around loosely coupling services, managing data across services, and establishing practices for a "living software" system with continuous deployment of services.
