The Cloud from Developers'Perspective

Cloud??? WTF?!?

Computer Located OUtside of Data Center

WTF?

Cloud forDevelopers?

What is Cloud?

Cloud ≈ multiple hardware machines combine computing power and resources Share them between multiple

applications To save costs and use resources more

efficiently

Public clouds Provide computing resources on

demand Publicly in Internet Paid or free of charge (to some limit)

Azure, Amazon AWS, Google App Engine, AppHarbor, Rackspace, Heroku, …

Why Cloud Matters?

Microsoft Azure

IBM Cloud

Apple iCloud

Oracle Public Cloud

SAP NetWeaver on Demand

Google App Engine

Amazon Web Services

HP Cloud Services

VMware Cloud Foundry

The Rackspace Cloud

Cisco Cloud Applicationsand Services

Cloud Computing ModelsInfrastructure as a Service (IaaS)

Virtual machines in the cloud on demand

Users install the OS and software they need

Platform as a Service (PaaS) Platform, services and APIs for

developers E.g. .NET + ASP.NET + WCF + SQL

Azure Java + JBoss + JSF + JPA + MongoDB JavaScript + Node.js + MongoDB +

RabbitMQ

Software as a Service (SaaS) Hosted application on demand (e.g.

WordPress or SugarCRM)

7

Cloud for DevelopersMoving to the cloud will require new skills New paradigms and APIs

E.g. NoSQL databases and MapReduce

New platforms and technologies New deployment model

The cloud still supports your existing skills Known technologies, e.g. ASP.NET

and WCF Your favorite programming

languages Like C#, Java and PHP

Relational databases and SQL

8

Cloud Architecture

The typical cloud architecture is multi-tier, SOA, highly-scalable and highly-available

At each tier different managed services, technologies and languages can run
