This document discusses deploying microservices on AWS. It begins by explaining what microservices are and then discusses hosting options on AWS including EC2, ECS, and Lambda. ECS is identified as the preferred option since it allows hosting containers with Docker. The document then covers deployment aspects like using source control with Git for multiple environments, building and testing code, deploying single services or entire clusters, live testing, and monitoring with alerts.

A Practical Introduction to Functions-as-a-ServiceValeri Karpov

This document discusses functions-as-a-service (FaaS) and provides an introduction to using AWS Lambda. It outlines the advantages of FaaS such as infinitely scalable devops without server management. It demonstrates a basic "Hello World" Lambda function and connecting Lambda functions to MongoDB. It notes limitations such as cold start times and that database performance is more important than app servers for most use cases. It recommends FaaS for non performance-sensitive backends and provides further reading on serverless platforms and async/await.

Real World Rails DeploymentAlan Hecht

This document discusses various options for deploying Rails applications in production environments, including Platform as a Service (PaaS) options like Heroku, shared web hosting, virtual private servers, and infrastructure as a service providers like Amazon Web Services. It also covers selecting and configuring a web server (Nginx or Apache), Rails application servers (Unicorn, Thin, Passenger), and deployment tools like Capistrano. The ideal scalable architecture uses a content delivery network, load balancers, and multiple application servers behind a reverse proxy like Nginx.

Azure Functions - the evolution of microservices platform or marketing gibber...Katherine Golovinova

ANTON BOYKO, Founder and main speaker of Ukrainian Microsoft Azure Community. When many people hear the word microservices, they think of Kubernetes. And it’s hard to blame them: the utilization of Docker containerization together with Kubernetes orchestration really seems like a match made in heaven. But, there is a new name in town: serverless (or FaaS). It seems it can offer you all the stuff that Kubernetes has and more. Native support for .NET, Java, Python, Node. Out-of-the-box binding for things like HTTP incoming requests (for Web API), incoming queue message (for processing async tasks), time-based trigger, etc. It also comes with micro billing (you pay only for execution time, not for idle time) and 0-to-infinite scalability. But is it all too good to be true? Aren't there any drawbacks? Is it all a huge marketing scheme to make us actually pay more? Let's find out.

Zapping ever faster: how Zap sped up by two orders of magnitude using RavenDBOren Eini

Join a real uplift experience with Hagay Albo, the CTO of the Zap/Yellow Page Group in Israel, in which he explains how his team was able to take a legacy (slow and hard to modify) group of sites and make them easier to work with, MUCH faster and greatly simplified the operational environment. By prioritizing high availability, flexible data modeling and focusing on raw speed Zap was able to reduce its load times by Two Orders of Magnitudes. Using RavenDB as the core engine behind Zap's new sites had improved site traffic, reduced time to market and made it possible to implement the next-gen features that were previously beyond reach.

Ruby SetupAlan Hecht

This document provides instructions for setting up Ruby and Rails on different platforms. It discusses using Rails Installer or Ruby Installer for Windows setup. It recommends Git for Windows, msysGit, or GitHub for Windows. It notes the OS X system versions of Ruby and Rails are often old and recommends using Homebrew. It provides instructions for installing GCC and prerequisites on Linux like Ubuntu before installing Ruby. It also discusses using RVM, rbenv, or pik for managing multiple Ruby versions.

Anton Boyko "The future of serverless computing"Fwdays

Are you still planning your servers capacity in CPU and RAM? Do you enjoy answering questions like “what amount of servers we need to buy to serve 10K and 10M users”? Do you enjoy paying for those servers while they are sitting idle? In my session I will talk about the current state and the future of serverless computing. I will show several demos that show how to start using serverless computing, what are the application scenarios for it, how it can scale, what it will cost, etc. This session will be useful for developers and architects who are seeking a way to create an app utilizing all your previous skills, but make it scalable, reliable, fast and cost efficient.

Total cloud immersionAvishai Ish-Shalom

6 years ago, I wrote my first "serverless" application: Fewbytes' clients timesheets interface. This was an AppEngine application, and its architecture was similar to other server applications - clients communicating with a central piece of code which talks on their behalf to other components. But today, with the growing power and sophistication of Cloud platforms, our familiar architectural patterns fail us. To fully unleash the power of the Cloud, a new type of architectural pattern is required, one in which there is no central server and many peers cooperate. We need a truly Cloud Native architecture: Total Cloud Immersion

RavenDB embedded at massive scalesOren Eini

1) RDI uses RavenDB embedded in over 36,000 restaurants with around 500,000 individual machines processing $50,000 per second in payments. 2) RavenDB allows for unit testing without mocking the database, advanced statistics on data persistence, and transparent replication with high availability. 3) The challenges of using RavenDB on specialized older hardware with low memory and ESENT include fine-tuning memory usage, disabling caching, and automating recovery from unclean shutdowns with ESENTUTL.EXE.

RubyConf Taiwan 2016 - Large scale Rails applicationsFlorian Dutey

This document discusses strategies for scaling large Rails applications. It advocates separating applications into thin controllers, fat models, and following principles like single responsibility and stateless objects. The document also recommends separating applications into layers like services, forms, policies, queries, adapters, and models. Services describe processes, forms convert inputs, policies describe permissions, queries access data, adapters translate between languages, and models manage data. It argues this architecture makes applications more flexible, testable, and debuggable while allowing for easier migration between providers.

Reasonable app developmentArnar Þór Sveinsson

The document discusses ReasonML, a dialect of OCaml that compiles to JavaScript. It summarizes: 1) The author uses ReasonML for various projects at Viska including 8 cloud functions, a web admin, and a React Native app with over 8,000 lines of ReasonML code and several open source binding libraries. 2) ReasonML allows developing both web and mobile apps with one codebase and team as it compiles to JavaScript, unlike React Native which requires separate teams. 3) ReasonML is advantageous over React Native as it is typed, has a fast compiler, and the functional features of OCaml, unlike the untyped and slow nature of JavaScript in React Native.

Pre-rendering single page appMichał Koźmiński

This document discusses pre-rendering apps for faster response times, SEO benefits, and support for slower devices. It describes two approaches: using Node.js with HTML parsing and JSDOM libraries, and Rendr, an open-source library from Airbnb that allows Backbone.js apps to run server-side using Express. Rendr replaces Backbone classes and standardizes rendering processes. The document provides instructions for migrating views and controllers to Rendr and setting up an Express app with a rendering configuration. Examples and additional resources are listed.

ASP.NET Core - Phillosophies, Processes and Tooling💻 Spencer Schneidenbach

Microsoft has built a rich ecosystem around the various flavors of ASP.NET – MVC, Web API and even WebForms have a place in the modern web development world. So what the heck is up with ASP.NET Core anyways? Microsoft has flipped the ASP.NET world on its head with this fast, cross-platform web framework, designed from the ground up with developers from all walks of life in mind – and the change isn’t as scary as you think. In this session, we’ll learn about ASP.NET Core and its design philosophies. We’ll learn how to leverage several popular development tools frequently used by developers outside of the ASP.NET ecosystem, including Gulp, Bower, Node and NPM, to build and run our application. Finally, we’ll use Visual Studio Code to create and run our very first ASP.NET Core project (on a Mac no less!) For current ASP.NET developers, we’ll also touch on the portability of your current ASP.NET code.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

The future of cloud programming

1. The Future of Cloud Programming Is Serverless and Concurrent

2. What’s this all about? Concurrent Programming Erlang, Java Go, Elixir, Scala Serverless Architecture AWS Lambda Azure Cloud Functions Backend as a Service (Baas) Google Firebase

3. Concurrency Doing a lot of things at once

4. The Basics ● Utilize multi-core systems ● Scale across multiple servers ● Low latency

5. Complications ● Hard to develop ● Hard to debug ● Different mindset ● Fewer developers

6. Benefits of Functional Programming ● Super Fast ● Fewer Bugs ● Easy to Test ● Concurrent by Default

7. 2 Million Websocket Connections On a SINGLE SERVER

8. The Future ● Better Languages ○ Elixir ○ Clojure ○ Scala ○ Go ● Strong VMs ○ JVM ○ Erlang VM ● More prolific

9. Serverless Functions as a Service (FaaS)

10. How it Works ● No Servers * ● Host provides resources ● Resources are on demand ● Function is executed

11. Advantages ● Scalability ● Cost ● Programming Model ● Deployment Process ● Reliability ● Throughput

12. MLB Statcast 30 JSON docs / second / game ~1k - 50k / JSON

13. Disadvantages ● Limited resources ● Short execution time ● Hard to debug ● Slow when unused ● Hard to monitor ● Hard to replicate

14. Serverless Providers

15. Serverless Frameworks

16. BaaS “Backend as a Service” - or - “How to stop worrying and love the cloud”

17. How it Works MAGIC!

18. Google someone hosts and maintains a centralized database How it Works

19. Advantages ● Centralized DB ● Near Real Time ● Updated by Multiple Users ● Cross Platform API ● Hosting Included (required)

20. Disadvantages ● Centralized DB ● Hosting Included (required) ● May be overkill ● Expensive at scale ● Not SQL (JSON)

21. Alternatives to Firebase

22. Review Concurrency ● Functional Programming ● Low Latency ● High Scale ● Maximize Resources Serverless ● High Throughput ● Low Cost ● High Scale ● Frequent small tasks BaaS ● Rapid Development ● Prototyping ● Near Real Time ● Central DB ● Frequent Updates
