AGENDA

Motivation

OWIN

Project K

Demo

MOTIVATION - HISTORY

1996 – ASP

2002 – ASP.NET

2008 – ASP.NET MVC

2010 – ASP.NET Web Pages

2012 – ASP.NET Web API, SignalR

2014 – ASP.NET 5

Other stacks: Spring, Rails, Sinatra, Django, Node, Go, …

MOTIVATION

System.Web basis for * web

WebForms bundled

Regression bugs We fix one bug and open new ones

Monolithic architecture

Slow release cycle

MOTIVATION

Performance

IIS stays “IIS is the fastest web server, as long you don’t load System.Web”

Evolutionary steps: MVC, WebAPI Released out-of-band

Move from big server apps to smaller client/device centric apps, microservices architecture, mobile clients, REST

Cloud, Docker, cross-platform

Web based IDEs, lightweight IDEs (Sublime, Atom)

MOTIVATION

Simplicity

OWIN

Open Web Interface for dot Net

Defines interface between app components Decouples app from framework, host and server

Open standard

Not revolution but evolution, influenced by other stacks

OWIN SPEC

using AppFunc = Func<

IDictionary<string, object>, // Environment

Task>; // Done

OWIN/KATANA ARCHITECTURE

SERVER (http.sys, IIS)

OWIN SPECSCommunity standard

No more System.Web, just dictionary of environment variables (request, response, etc)

Async

Microsofts implementation: Katana v1-3 is in ASP.NET vCurrent

v4 is vNext

MVC 6, WebAPI, SignalR

Helios, Kestrel, Nowin

VNEXTProject K: KRE, KLR, KPM, KVM

2 frameworks: Full CLR

Core CLR: cross-platform, bin-deployable, ~11MB

Started as OWIN-based, now it’s OWIN - compatible

Faster dev cycle (features shipped as packages, framework as part of an app) DevOps responsible for security patching!

More control (zero day sec. patches, pull vs push model)

Perf: startup time, memory (>90% reduction), modular
