Microservice architecture

Microservices architecture is an approach to developing a single application as a suite of small services that communicate with each other using lightweight mechanisms like REST APIs. Each service runs in its own process and communicates through APIs, allowing independent scaling of services. This contrasts with monolithic architecture where all application components are deployed together in one process. Microservices provide benefits like independent scalability, fault isolation, and faster development cycles compared to monolithic applications. Common technologies used in microservices include API gateways, service discovery, configuration management, distributed logging, and messaging.

The document discusses microservice architecture and compares it to monolithic architecture. It describes microservices as small, discrete, isolated services that can be deployed separately. A monolith is a single application combining all business logic and data access. The document outlines characteristics of microservices such as single responsibility, statelessness, independent data management and communication through APIs or message queues. It also covers deployment, testing, monitoring, metrics and the need for automation and a culture open to change when using microservice architecture.

This is my presentation at DevNexus 2017 in Atlanta. Containers are a default choice for packaging and deploying Microservices. You will understand why containers are a natural fit for microservices, the value a container platform brings to the table, how to structure your microservices running as containers on an enterprise ready Kubernetes platform aka, OpenShift. We will also look at a sample microservices application packaged and running as containers on this platform.

Companies looking to speed up their software development are adopting microservices architectures (MSA). Building applications as groups of smaller components with fewer dependencies helps companies such as Comcast, Capital One, Uber, and Netflix deliver more frequent releases and thus innovate faster. An important consideration in adopting an MSA is deciding how individual services should communicate between each other. Adding a message queue such as RabbitMQ to handle interservice messages can improve communication by: - Simplifying our services so they only need to know how to talk to the messenger service. - Abstracting communication by having the messenger service handle sophisticated orchestration patterns. - Scaling message throughput by increasing the cluster size of the messenger service. In this webinar we'll discuss: - Requirements for communicating between microservices - Typical messaging patterns in microservice architectures - Use cases where RabbitMQ shines - How to use the RabbitMQ service for Pivotal Cloud Foundry to deploy and run your applications We’ll also demonstrate how to deploy RabbitMQ in Pivotal Cloud Foundry, and how to incorporate it in microservices-based applications.

This document discusses cloud native microservices and key components for implementing them. It provides an overview of microservices principles and design patterns, and describes the cloud native landscape including containers, Kubernetes, service meshes like Istio, and other open source tools. It also discusses architectures like ONAP and considerations for deploying virtual network functions using microservices.

The Microservices approach is a new way of building composable, cloud-native applications. This session is designed for developers who are transforming existing applications to Microservices, or creating new Microservices style applications. The session will cover best practices, patterns including Service Registration and Discovery, and key development tools required for building distributed Microservices style applications. The session will also cover best practices for automating the operations of these applications, using container orchestration services.

Microservice composition or integration is probably the hardest thing in microservices architecture. Unlike conventional centralized ESB based integration, we need to leverage the smart-endpoints and dumb pipes terminology when it comes to integrating microservices. There two main microservices integration patterns; service orchestration (active integrations) and service choreography (reactive integration). In this talk, we will explore on, Microservice Orchestration, Microservice Choreography, Event Sourcing, CQRS and how Kafka can be leveraged to implement microservices composition

Binary Studio MEET FOR IT gatherings: 5th of March 2016 our meetup was devoted to .NET platform and took part in Lviv, Ukraine.

This presentation outlines the benefits of implementing a Microservice over a monolithic architecture.

The presentation provided an introduction to microservices, including definitions from various experts. It discussed the benefits of microservices like independent deployability and scalability, as well as challenges around complexity. Examples of microservice architectures using an API gateway and Spring Boot were presented. Tips included references to documentation on microservice patterns and cloud-native computing. The presentation concluded with a call for questions.

Istio is a service mesh—a modernized service networking layer that provides a transparent and language-independent way to flexibly and easily automate application network functions. Istio is designed to run in a variety of environments: on-premise, cloud-hosted, in Kubernetes containers.

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

Presentation from WJAX 2015 with Oliver Gierke. Compares REST and Messaging as an integration approach for Microservices.

This document discusses integration patterns for microservices and cloud native architectures. It begins by establishing the importance of integration for digital transformation. Common integration challenges with microservices like smart endpoints and dumb pipes are described. The document then outlines various microservices integration patterns like active/reactive composition and anti-corruption layers. It presents WSO2's integration platform as a solution for building microservices integration and discusses related concepts like service meshes. The key takeaway is that a hybrid approach combining various integration patterns in an iterative manner is needed for microservices integration.

- 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.

Developing and managing hundreds (or maybe thousands) of microservices at scale is a challenge for both development and operations teams. We have seen over the last years the appearance of new frameworks dedicated to deliver ‘Cloud Native’ applications by providing a set of (out of box) building blocks. Most of these frameworks integrate microservices concerns at the code level. Recently, we have seen the emerging of a new pattern known as sidecar or proxy promoting to push all these common concerns outside of the business code and provides them on the edge by integrate a new layer to the underlying platform called Service Mesh. Istio is one of the leading Service Mesh implementing sidecar pattern. We will go during the presentation throw the core concepts behind Istio, the capabilities that provides to manage, secure and observe microservices and how it gives a new breath for both developers and operations. The presentation will be guided by a sequence of demo exposing Istio capabilities.

#Codemotion Rome 2018 - Containers provide a consistent environment to run services. Kubernetes help us to manage and scale our container cluster. Good start for a loosely coupled microservices architecture but not enough. How do you control the flow of traffic & enforce policies between services? How do you visualize service dependencies & identify issues? How can you provide verifiable service identities, test for failures? You can implement your own custom solutions or you can rely on Istio, an open platform to connect, manage and secure microservices.

Microservices architecture is an evolution of service-oriented architecture (SOA) principles applied to application design and development. Some key differences include: - SOA focuses on exposing application functionality as services at the enterprise level, while microservices focus on developing individual applications as a suite of independently deployable services. - Microservices are typically smaller, lighter weight services focused on a single task, as opposed to monolithic applications. They communicate with lightweight protocols like HTTP. - Microservices aim to support continuous delivery and deployment, with goals of automation, resilience, and loose coupling between services. - Individual microservices can be developed and scaled independently. This provides benefits like enabling continuous delivery and deployment. So in summary,

In this presentation we will talk about the Microservices approach and how it can be implemented in IoT ecosystem. The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. A possible solution to easily control the IoT systems is to create an intelligent platform using a microservices architecture.

The document discusses microservice patterns for implementing microservices. It begins with an overview of pattern languages and how they can be applied to microservices. It then covers several common microservice patterns including service discovery, communication styles, deployment strategies, and reliability patterns like circuit breakers.

Guest lecture talk in the CMU's Foundation of Software Engineering course: http://www.cs.cmu.edu/~ckaestne/15313/2017/

This slide deck explains why we need microservices and how we can develop microservices using opensource microservice frameworks.

A proper Microservice is designed for fast failure. Like other architectural style, microservices bring costs and benefits. Some development teams have found microservices architectural style to be a superior approach to a monolithic architecture. Other teams have found them to be a productivity-sapping burden. This material start with the basic what and why microservice, follow with the Felix example and the the successful strategies to develop microservice application.

This document provides an overview of microservices, including: - What microservices are and how they differ from monolithic architectures and SOA. - Common microservice design patterns like aggregator, proxy, chained, and asynchronous messaging. - Operational challenges of microservices like infrastructure, load balancing, monitoring. - How microservices compare to SOA in terms of independence, scalability, and technology diversity. - Key security considerations for microservices related to network access, authentication, and operational complexity.

Understand the reasons to opt for JavaScript Microservices and look at the key steps involved in building microservices with Node.js.

The document discusses microservices and API management. It defines microservices as small, independent processes communicating via APIs to compose complex applications. Benefits include improved modularity, scalability, and fault isolation. API management provides tools to publish, secure, monitor, and analyze APIs. It allows enterprises to expose APIs internally or externally in a controlled manner. The document outlines considerations around microservices and features of API management systems.

A microservices architecture is a type of application architecture where the application is developed as a collection of services. It provides the framework to develop, deploy, and maintain microservices architecture diagrams and services independently. Microservices are the blocks of your application and perform different services, while REST APIs work as the glue or the bridge that integrates these separate microservices. APIs can be made up, wholly or partially, out of microservices. Developers can use Microservices for a lot more, though
