Microservice architecture Microservices vs monolith Design patterns for microservice architecture Further reading

Micro-services architecture is an evolutionary design ideal for evolutionary systems where you can’t fully anticipate the types of devices that may one day be accessing your application

KnockoutJS is a JavaScript library that provides declarative bindings between a data model and UI. It exposes the MVVM pattern, separating model, view, and view model concerns. Two-way data binding automatically synchronizes data between the model and view. Observables notify of changes and detect dependencies, enabling two-way binding between UI elements and the JavaScript view model. KnockoutJS is lightweight, fully documented, and suitable for building small to medium single-page applications.

This document summarizes one organization's journey from a monolithic application architecture to a microservices architecture. It describes some of the pains of maintaining a monolithic application. It then discusses strategies for breaking the monolith into independently deployable microservices at low risk, including identifying module boundaries, deploying and releasing services independently, virtualizing data integration, and using traffic mirroring. The goal is to increase development velocity while lowering risk.

Henry Stapp, Director of Product Management at Apcera, explores the promises of the cloud and how new technologies (containers, micro-services, etc.) enable unparalleled speed and flexibility.

The document discusses the evolution of IT infrastructure from siloed application architectures to microservices and network-centric architectures. It outlines several principles of microservices, including smart endpoints and decentralized governance. It also notes some disadvantages of microservices like operational overhead and distributed system complexity. Finally, it discusses future challenges like moving from monolithic to multi-cloud architectures and how organizations must structure themselves around network-centric designs.

ITIL (IT Infrastructure Library) is a framework for managing IT services and ensuring they meet customer expectations. This presentation discusses key ITIL concepts like defining IT services, delivering services, measuring quality of service, and operational management through monitoring, reporting on KPIs and SLAs, problem and change management. Continuous improvement is important to regularly review services and customer requirements. Standard service requests are repeatable with set processes and timelines.

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

Early Draft: Service Mesh allows developers to focus on business logic while the crosscutting network data layer code is handled by the Service Mesh. This is a boon because this code can be tricky to implement and hard to test all of the edge cases. Service Mesh takes this a few steps further than AOP or Servlet Filters or custom language-specific frameworks because it works regardless of the underlying programming language being used which is great for polyglot development shops. Thus standardizing how these layers work, while allowing teams to pick the best tools or languages for the job at hand. Kubernetes and Istio Service Mesh automate best practices for DevSecOps needs like: failover, scale-out, scalability, health checks, circuit breakers, rate limiters, metrics, observability, avoiding cascading failure, disaster recovery, and traffic routing; supporting CI/CD and microservices architecture. Istio’s ability to automate and maintaining zero trust networks is its most important feature. In the age of high-profile data breaches, security is paramount. Companies want to avoid major brand issues that impact the bottom line and shrink market capitalization in an instant. Istio allows a standard way to do mTLS and auto certificate rotation which helps prevent a breach and limits the blast radius if a breach occurs. Istio also takes the concern of mTLS from microservices deployments and makes it easy to use taking the burden off of application developers.

Everyone is excited about cloud-native applications. And for good reason! They're scalable, resilient, portable across cloud environments, and make it easier to incorporate customer feedback quickly. But there's a catch: cloud-native applications fundamentally change the way you provision, deploy, and manage your infrastructure. That's where DevOps, microservices, and containers come in. This session will show you how to combine them to create a highly-automated continuous delivery platform. By streamlining the process to resemble factory assembly lines, you can adapt quickly to market changes and keep your customers happy – without burning your team out.

The introduction covers the following 1. What are Microservices and why should be use this paradigm? 2. 12 factor apps and how Microservices make it easier to create them 3. Characteristics of Microservices Note: Please download the slides to view animations.

Presenting key architectural concepts of the Microservices Architecture(MSA) and how you can use those architectural principles in practice.

A high-level overview of Microservices architecture topics you should be familiar with before you actually start breaking your monolith into microservices

The document discusses reactive applications and the Typesafe Reactive Platform. Reactive applications are message-driven, elastic, resilient, and responsive. They react to changes, scale up and down based on demand, handle failures, and provide low-latency responses. The Typesafe platform includes Akka for building concurrent applications and Play Framework for developing web applications. Both use reactive principles and support features like clustering, event sourcing, and web services. Typesafe delivers training and support for organizations adopting a reactive approach using their Java-based tools.

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 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.

Diapositivas con el contenido de mi charla en el XXIII BetaBeers. Microservices vs Monolithics. Granada - 14/12/2017

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. In this slide we have discussed, Monolithic application vs Microservices, applicable scenarios for adopting the architectural pattern, when we need microservices, what are the benefits, case study of an e-commerce platform by compartmentalizing the scopes into different sample microservices and Docker implementations. The full talk has been recorded here: https://youtu.be/tNlp7HS533g

This document provides an overview of microservices and monolithic architectures. It discusses how monolithic applications are self-contained and execute end-to-end tasks, while microservices are small, independent services that communicate to perform tasks. The document outlines characteristics of each approach and compares their advantages and disadvantages, such as improved scalability, deployment and innovation with microservices versus better performance with monolithic architectures. Examples of companies using microservices are also provided.

Whar are microservices and microservices architecture (MSA) How we reach them? Are they the same or SoA or not? When to use them? What are the key characteristics? Slides of my talk given in #Gapand2017 in Andorra

“ The Microservices architecture has many appealing qualities, but the road towards it has painful traps for the unwary. This book will help you figure out if this path is for you, and how to avoid those traps on your journey.” —Martin Fowler Chief Scientist, ThoughtWorks

A journey of a FinTech application into the cloud, starting as a monolith and growing to MicroServices. Why going functional is so good for finance technology, and how Scala helped us build a better application.

This document discusses deployability and continuous deployment in the context of microservice architectures. It begins by describing National ICT Australia (NICTA) and its work in information and communications technology research. It then discusses how microservice architectures support continuous deployment by allowing individual teams to deploy new versions of their services independently without coordination. Key aspects of microservice architectures that enable this include: each service having a single responsibility; services communicating asynchronously via messaging; and services registering themselves with a discovery service. The document also discusses how feature toggles and canary deployments can be used to maintain consistency when deploying new versions of services.
