What is Serverless?
Not involving a server; composed only of clients.
http://www.wordsense.eu/serverless
Serverless doesn’t mean servers are no longer
involved. It simply means that developers no
longer have to think "that much" about them.
Computing resources get used as services
without having to manage around physical
capacities or limits.

What is Microservices?
In computing, microservices is a software
architecture style in which complex applications are
composed of small, independent processes
communicating with each other using language-
agnostic APIs. These services are small, highly
decoupled and focus on doing a small task,
facilitating a modular approach to system-building.

Building .NET Microservices

VMware Tanzu

SpringOne Platform 2016 Speakers: Kevin Hoffman; Advisory Solutions Architect, Pivotal & Chris Umbel; Advisory Architect, Pivotal With the advent of ASP.NET Core, developers can now build cross-platform microservices in .NET. We can build services on the Mac, Windows, or Linux and deploy anywhere--most importantly to the cloud. In this session we'll talk about Cloud Native .NET, building .NET microservices, and deploying them to the cloud. We'll build services that participate in a robust ecosystem by consuming OSS servers such as Spring Cloud Configuration Server and Eureka. We'll also show how these .NET microservices can take advantage of circuit breakers and be automatically deployed to the cloud via CI/CD pipelines.

An Unexpected Solution to Microservices UI Composition

Dr. Arif Wider

This document describes a company's transition from a monolithic .NET application to a microservices architecture hosted on AWS. It details their use of a UI composition pattern using Nginx, ESI, and Jigsaw to compose fragments from different services into complete pages. This allows independent deployment of features while maintaining performance. Key aspects include caching of assets and responses, combining stylesheets and scripts, and isolation of services through separate CSS and JS packages.

The document discusses digital transformation with Red Hat hybrid cloud. It begins by outlining some common business pain points and challenges around technical debt, digitalization, time to market, and return on investment. It then covers key technology trends like cloud-native applications, AI/ML, IoT, blockchain, and more. The rest of the document focuses on how Red Hat's portfolio, including OpenShift and middleware solutions, can help customers address these trends and challenges as part of their digital transformation journey by enabling new application development approaches, modernizing infrastructure, and optimizing processes.

Javantura v4 - Cloud-native Architectures and Java - Matjaž B. Jurič

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

Cloud-native architectures and microservices allow software to be built faster, more resiliently, and scalably. Microservices involve decomposing applications into loosely coupled services that are independently deployable. Key aspects of microservices include explicit interfaces, independent scaling, and fault tolerance through approaches like circuit breakers. Containerization helps with microservices by enabling portable, lightweight execution of individual services. APIs are critical for communication between microservices and services should be stateless and immutable.

Design patterns for microservice architecture

The Software House

The presentation from our online webinar "Design patterns for microservice architecture". Full video from webinar available here: https://www.youtube.com/watch?v=826aAmG06KM If you’re a CTO or a Lead Developer and you’re planning to design service-oriented architecture, it’s definitely a webinar tailored to your needs. Adrian Zmenda, our Lead Dev, will explain: - when microservice architecture is a safe bet and what are some good alternatives - what are the pros and cons of the most popular design patterns (API Gateway, Backend for Frontend and more) - how to ensure that the communication between services is done right and what to do in case of connection issues - why we’ve decided to use a monorepo (monolithic repository) - what we’ve learned from using the remote procedure call framework gRPC - how to monitor the efficiency of individual services and whole SOA-based systems.

agile microservices @scaibo

Ciro Donato Caiazzo

The document discusses agile microservices and their advantages over monolithic architectures. It describes how to decompose a monolithic real estate management application into independent microservices for properties, facilities, and engineering. Microservices allow for improved independence, speed of development, automation, and use of different technologies. Inter-service communication can occur over REST, HTTP, or AMQP, while an API gateway pattern hides service complexity from clients. Cloud computing platforms like Docker and Convox can deploy and manage containerized microservices. The Internet of Things connects physical devices to these services over protocols like MQTT and WebSocket.

Spring IO 2016 - Spring Cloud Microservices, a journey inside a financial entity

Toni Jara

AngularJS Vs NodeJs

Marie Weaver

There is increasing demand for more robust web applications due to the rise of internet and mobile usage. This has led to the creation of many new development tools and frameworks. Two popular options are Angular and Node.js, which both have their advantages. Angular is a front-end JavaScript framework well suited for single page apps, while Node.js is a back-end runtime for building scalable servers using JavaScript. Key differences are that Angular supports two-way data binding and MVC architecture, while Node.js enables database queries and non-blocking asynchronous I/O. Developers must consider the needs of their specific project to determine whether Angular or Node.js is the best solution.

micro services architecture (FrosCon2014)

smancke

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.

Introduction to Microservices

Roger van de Kimmenade

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.

Microservice architecture

Xavier Fornés Arrabal

The document discusses microservice architecture and contrasts it with monolithic applications. It describes characteristics of microservices including componentization via independently deployable services, organizing teams around business capabilities rather than technology, treating products not projects with dedicated teams, using smart endpoints and dumb pipes for communication, decentralized governance and data management, and designing for evolutionary development and failure. The document provides examples of these concepts and references additional resources on microservice architecture.

Introduction to Microservices

André Faria Gomes

The document discusses some of the pros and cons of using microservices compared to monolithic applications. Some advantages of microservices include that they are simpler to develop, allow for faster build and deployment times, enable more scalable development with empowered teams, and provide more freedom to try different technologies. Some challenges of microservices include that they have complex operations and distribution, require managing multiple databases and transactions, are harder to test as distributed systems, and require coordination when changes affect multiple services.

A High-Performance Solution to Microservice UI Composition @ XConf Hamburg

Dr. Arif Wider

This document proposes an approach called Jigsaw for composing microservice user interfaces that balances team autonomy and page performance. Jigsaw defines pages as publicly accessible endpoints that include fragments from other services using server-side includes. The fragments adhere to contracts and can be cached. An Nginx proxy handles routing to services and uses modules like ngx_pagespeed to optimize and combine assets for improved page load performance when composing the user interface from multiple autonomous microservices.

Knowledge share about scalable application architecture

AHM Pervej Kabir

This document discusses scalable web application architectures. It begins by defining scalability and explaining the objectives of scalable systems, including handling traffic and data growth while maintaining system maintainability. There are two main types of architectures discussed: network-based architectures and application-based architectures. Network-based architectures focus on load balancing and distributing traffic across servers, while application-based architectures separate an application into tiers or layers, with the most common being three-tier architectures using a model-view-controller (MVC) pattern. The document provides an overview of common scalability patterns including caching, databases, and file storage solutions.

Rapid, Scalable Web Development with MongoDB, Ming, and Python

Rick Copeland

In 2009, SourceForge embarked on a quest to modernize our websites, converting a site written for a hodge-podge of relational databases in PHP to a MongoDB and Python-powered site, with a small development team and a tight deadline. We have now completely rewritten both the consumer and producer parts of the site with better usability, more functionality and better performance. This talk focuses on how we're using MongoDB, the pymongo driver, and Ming, an ORM-like library implemented at SourceForge, to continually improve and expand our offerings, with a special focus on how3 anyone can quickly become productive with Ming and pymongo without having to apologize for poor performance.

Migrating a Monolithic App to Microservices on Cloud Foundry

Tony Erwin

Originally presented by Tony Erwin and Brian Martin at the CF Summit in Santa Clara, CA on May 12, 2015. The Bluemix UI is the front-end to Bluemix, IBM's PaaS cloud hosting platform built on top of CloudFoundry. The demands placed on the UI have outpaced the original implementation as a monolithic single-page app. To deal with these challenges, the UI is being migrated to leverage a more modern and scalable microservices architecture. We discuss the advantages of microservice architectures, approaches to migrating a monolith to microservices in a live product, and real-life lessons learned in the deployment and management of microservices in a CloudFoundry environment.

Microservices and modern backends - Azure Meetup Frankfurt

Damir Dobric

This document discusses microservices and related Azure services. It begins by defining services and microservices, then discusses issues with monolithic applications that microservices aim to address like scalability, flexibility, and complexity. It covers integration styles for microservices like messaging and REST APIs. Specific Azure services are demonstrated that help with microservices development like Service Bus for messaging, App Services for hosting, and Durable Task Framework for orchestration. The key lessons are that microservices improve scalability and agility over monoliths but require more operational focus and integration complexity between independently deployable services.

A High-Performance Solution To Microservices UI Composition

Alexey Gravanov

So you have decided to go for Microservices and you want to achieve maximum autonomy for your teams. However, at the front end your services still have to be joined into a single page.Here you have two options: Either have a single UI layer which all teams depend on or let each service render its own UI and compose these UI pieces later on. In the course of moving the Autoscout24 platform - one of Europe’s leading internet car portals - to an AWS-hosted Microservice architecture, we favored autonomy and therefore decided for the UI Composition approach. During this process we faced all the challenges of UI Composition, such as performance, consistency, isolation, and testing. Learn how we started off with a rather complex attempt and then managed to greatly improve and simplify our solution.

Building a Web Frontend with Microservices and NGINX Plus

NGINX, Inc.

Watch the webinar on demand at: nginx.com/resources/webinars/web-microservice-controlled-stateless-and-connected While many articles and books have been written about service design, there is a scarcity of information about how to integrate rich, user-experience-based web development onto a microservice-based application. In many respects the web frontend is the most complex part of the application, but it needs to scale and interface with your system just like any other microservice. The question is, how will your frontend system access your backend microservices? What will you do to make the frontend as stateless and ephemeral as the rest of your microservices? How will you provide your JavaScript application components with access to your microservices? Watch this webinar to learn how to: * Build your frontend using Model-View-Controller frameworks * Implement session state as a cached component in an attached resource * Use NGINX Plus routing and load balancing to give JavaScript access to microservices

Hitchhiker's Guide to"'Serverless" Javascript - Steven Faulkner, Bustle

NodejsFoundation

Tools like AWS’s Lambda, Google's Cloud Functions, and many others are allowing us to create “serverless” applications. At Bustle (a top 30 website in the US) we are taking full advantage of this new infrastructure. APIs, databases, searching, indexing, server side rendered javascript, are all being handled without deploying any of our own servers. And the best part? It costs orders of magnitude less than our old VM based deployments. I’ll walk attendees through our entire serverless stack. I'll talk about the good, the bad, and the ugly. I'll share real numbers from production systems. The goal is that attendees will leave with concrete knowledge of what going serverless really means and be able to decide if it makes sense for their own infrastructure.

Take Data Validation Seriously - Paul Milham, WildWorks

NodejsFoundation

Why is data validation important? What are effective ways to ensure data is valid? In this session we'll explore how data validation is directly linked to security, stability and developer productivity when dealing with untrusted or unknown data sources. We'll discuss the dangers of code that does not validate its data - everything from injection to DOS attacks. We'll go hands on with joi (https://github.com/hapijs/joi) and Express (http://expressjs.com/) to see how data validation can make code easier to work with. No more "Uncaught ReferenceError" or if null checks littered around the code base. In the end, we'll see how code can be secure, stable and magically awesome to work with.

Developing Nirvana - Corey A. Butler, Author.io

NodejsFoundation

It is common to hear how much impact user experience has on the success of an application. Similarly, developer experience (DX) has a huge impact on the quality and usefulness of code. Why are some libraries so popular while others disappear? How do you create code people will actually use? In this talk, Corey Butler will review the oft-overlooked art of developer workflow. He will share tips and tricks used to make life sane, and even pleasurable, acquired on his journey through open source projects like NVM for Windows, Fenix Web Server, and node-windows/linux/mac. Find out how a focus on DX can elevate you and your code from obscurity to nirvana.

Real-Life Node.js Troubleshooting - Damian Schenkelman, Auth0

NodejsFoundation

When building a large enough set of services using node.js, there will be a point when you find that your application is suffering from performance or memory issues. When this happens, you have to roll up your sleeves, get your tools and start digging. This talk explains how you can use tools such as ab, flame graphs, heap snapshots and Chrome's memory inspector to find the cause of these. We will go over two real life issues, a CPU bottleneck and a memory leak, we found while building our services at Auth0, and also explain how we fixed them.

Multimodal Interactions & JS: The What, The Why and The How - Diego Paez, Des...

NodejsFoundation

The term 'multimodal interactions' (MMI) on the HCI field refers to the situation where a system offers many ways of interaction. This talk combines an academic subject with the daily JS we already know. It is an effort to bring together two, at first, different worlds looking for a win-win situation. On the one hand, academia could enjoy getting a novel approach to a particular problem thanks to our awesome JS. On the other, the industry can get new ways of interaction which can be applied on a variety of context and/or products. In short, the talk contains: - A quick introduction to MMI (Multimodal Interactions) - A particular novel approach to add support for MMI on Web Apps. - Short list of related open problems or possible research lines to pursuit.

NodejsFoundation

Among many things I love, what I really appreciate doing is the different, and learn with it. Breaking barriers is complicated for any person. Knowledge barriers many times are formed by ourselves by incomplete parts of our mind's puzzle. What If I could help you out with some piece of Artificial Intelligence, without "puzzling" your head? This project consists of an A.I. coded in Node.JS that learns by itself to play the "Google Chrome"'s Dino game (the one that pops up when there is no internet). Using Neural Networks, and a Genetic Algorithm, I could manage to let the computer learn by itself how to play the game like a ninja. The project has been hosted in github (https://github.com/ivanseidel/IAMDinosaur) and it's called IAMDinosaur.

Node's Event Loop From the Inside Out - Sam Roberts, IBM

NodejsFoundation

Do you think Node is asynchronous because it uses a thread pool for network interactions? Do you there is a relationship between "event emitters" and the "event loop"? I will be working through these misaprehensions as well as others, showing how the Node.js event loop really works. There are many, many pictures and blogs on this topic, but many of them are subtly wrong, or outright misleading. Despite that its event loop that is key to Node's scalability and performance, it remains a misunderstood black box to many. I will show how it works - C code may be seen! - talk about why it works that way, and what some of the implications are for Node developers, as well as briefly describe some changes that the Node core team are considering with respect to how Node uses libuv.

Math in V8 is Broken and How We Can Fix It - Athan Reines, Fourier

NodejsFoundation

The built-in JavaScript Math library is used in virtually every Node.js application, from generating random ids to calculating exponential back-off times to computing basic performance metrics. When using the Math library, most developers simply assume that the underlying implementations are accurate, performant, and correctly implemented. In this presentation, Athan Reines will discuss why this assumption is often false and show the various ways in which the standard library is broken. The presentation will present the algorithms used, their performance and accuracy, and how they have downstream effects on users of these libraries. The presentation will conclude by highlighting how community solutions are stepping up to fix these problems and identity opportunities for additional improvements.

What serverless means for enterprise apps

Sumit Sarkar

There’s a new approach to app development ripe with misconceptions and more buzzwords to translate to business sponsors. Industry analysts call it serverless, but it’s also known as backend as a service (BaaS), function as a service (FaaS), cloud-native architectures, or microservices—just to name a few. Whatever you call it, this approach is giving developers new freedom to focus on frontend functionality and deliver better, more innovative user experiences and ultimately establish value faster. Let’s discuss the pros and cons of serverless in enterprise architectures.

Application Centric Microservices from Redhat Summit 2015

Ken Owens

When Cisco started envisioning the future of its application development platforms, the ability to create applications that are cloud-native with elastic services, network-aware application policies, and micro-services was strategic to the company. When the decision to build and operate a Cisco cloud service delivery platform for collaboration, video, and Internet of Things (IoT) application development was made, OpenStack and micro-services became central to our application architectures and strategic to our vision as a company. This presentation will look at the journey Cisco developers took to transform to an application-centric OpenStack platform for application development in a secure, network-centric, and completely open source manner. The importance of the platform being Red Hat Enterprise Linux OpenStack Platform and using OpenShift by Red Hat and the contribution to the community will be described. The micro-services architecture and service-oriented DevOps lessons learned for enabling massive scalable and continuous delivery of software will be presented and demoed.

Launching your Application the Amazon Way - AWS Startup Day Boston 2018.pdf

Amazon Web Services

Chris Munns is a senior developer advocate for AWS Serverless. He discussed how Amazon transformed its development practices from 2001-2009 by moving from monolithic architecture to microservices and two-pizza teams. This improved speed of development. In 2009, surveys found developers still felt slowed by manual processes, so Amazon implemented continuous delivery pipelines to automate deployments, further increasing developer happiness. AWS Code services like CodeCommit, CodeBuild, CodeDeploy and CodePipeline help implement similar practices for automated deployments.

Designing Microservices

David Chou

The document discusses microservices and provides information on: - The benefits of microservices including faster time to market, lower deployment costs, and more revenue opportunities. - What defines a microservice such as being independently deployable and scalable. - Differences between monolithic and microservice architectures. - Moving applications to the cloud and refactoring monolithic applications into microservices. - Tools for building microservices including Azure Service Fabric and serverless/Functions. - Best practices for developing, deploying, and managing microservices.

The Morality of Code - Glen Goodwin, SAS Institute, inc.

The act of writing code seems pretty innocuous. But what if it isn't? What if the code we write was being used in the wrong ways to hurt, to destroy, to exploit? What are the moral implications we should be considering as we hack away late into the night? How do we do the right thing in a world of software patents, privacy concerns, open source, and technological anarchy? Are we asking ourselves the right questions to find our own personal moral guidelines for writing code or are we just hoping for the best? This talk aims to not give anyone the answers but instead focus on the questions so that each of us can come to our own answers for ourselves.

Real-Time Machine Learning with Node.js - Philipp Burckhardt, Carnegie Mellon...

NodejsFoundation

Real-time machine learning provides statistical methods to obtain actionable, immediate insights in settings where data becomes available in sequential order. After providing an overview of state of the art real-time machine learning algorithms, we discuss how these algorithms can be leveraged from within a Node.js application. We will see why the powerful API of the core stream module makes Node.js a more attractive platform for such tasks compared to languages traditionally used for scientific computing such as R, Python or Julia. Finally, we will discuss best-practices and common pitfalls that one faces when using these algorithms.

The JavaScript landscape and why it is the language of the next decade. 2. Evolution of Node and apps built on it 3. Solving the problems of scale, high uptime, multi channel and secure applications with Node 4. Node toolkit (various frameworks and supporting technologies) 5. Pitfalls to guard against

Workshop: Science Meets Industry: Online Behavioral Experiments with nodeGame...

NodejsFoundation

The goal of social science research is to discover fundamental features of human behavior. One of the best environments to accomplish this task are "games." Scientific behavioral experiments are a particular type of games, where the players' preferences are revealed through strategic interactions. "Gamification" -- the general technique of applying behavioral economics insights to understand any type of problems through games -- is increasingly been used in corporate business. This talk introduces the open-source project nodeGame (nodegame.org), a framework in Node.js to create and manage real-time and discrete-time synchronous behavioral experiments. The basic API for creating and running behavioral experiments in a stand-alone server or on the cloud is presented, and techniques to recruit participants from the Amazon Mechanical Turk labor market and other sources such as Volunteer Science are discussed. The talks also peeks into the world of academia, showing how the availability of data and new quantitative methodologies has changed the way social scientists do research. Their current and future needs for better, more reliable software, simple APIs, and down-to-Earth documentations are discussed.

Text Mining with Node.js - Philipp Burckhardt, Carnegie Mellon University

NodejsFoundation

Today, more data is accumulated than ever before. It has been estimated that over 80% of data collected by businesses is unstructured, mostly in the form of free text. The statistical community has developed many tools for analysing textual data, both in the areas of exploratory data analysis (e.g. clustering methods) and predictive analytics. In this talk, Philipp Burckhardt will discuss tools and libraries that you can use today to perform text mining with Node.js. Creative strategies to overcome the limitations of the V8 engine in the areas of high-performance and memory-intensive computing will be discussed. You will be introduced to how you can use Node.js streams to analyse text in real-time, how to leverage native add-ons for performance-intensive code and how to build command-line interfaces to process text directly from the terminal.

Take Data Validation Seriously - Paul Milham, WildWorks

NodejsFoundation

Why is data validation important? What are effective ways to ensure data is valid? In this session we’ll explore how data validation is directly linked to security, stability and developer productivity when dealing with untrusted or unknown data sources. We’ll discuss the dangers of code that does not validate its data - everything from injection to DOS attacks. We’ll go hands on with joi (https://github.com/hapijs/joi) and Express (http://expressjs.com/) to see how data validation can make code easier to work with. No more "Uncaught ReferenceError" or if null checks littered around the code base. In the end, we’ll see how code can be secure, stable and magically awesome to work with.

Graspan: A Big Data System for Big Code Analysis

Aftab Hussain

We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs. We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations. These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18. - Accepted in ASPLOS ‘17, Xi’an, China. - Featured in the tutorial, Systemized Program Analyses: A Big Data Perspective on Static Analysis Scalability, ASPLOS ‘17. - Invited for presentation at SoCal PLS ‘16. - Invited for poster presentation at PLDI SRC ‘16.

Measures in SQL (SIGMOD 2024, Santiago, Chile)

Julian Hyde

SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries. SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL. To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context. A talk at SIGMOD, June 9–15, 2024, Santiago, Chile Authors: Julian Hyde (Google) and John Fremlin (Google) https://doi.org/10.1145/3626246.3653374

Microservice Teams - How the cloud changes the way we work

Sven Peters

A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams? Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
