Write a Cloud application on Amazon Web Services

I EC2: virtual machines on demand (fairly standard API)

I S3: data storage (fairly standard API)

I But there is more:I RDS: relational databaseI SimpleDB: non-relational databaseI CloudWatch: performance monitoringI AutoScale: automatic application scalingI CloudFront: content delivery serviceI etc.

These services are speci�c to Amazon Web services

Customer lock-in

I If you use any of the �fancy� services from your Cloud provideryou lock yourself in

I The pricing scheme may changeI The Cloud may decide to stop business with youI The Cloud may go out of businessI The Cloud may have outages

I How do we move to a di�erent hosting environment?I Find an alternative for all services you were usingI Re-implement large parts of the applicationI This costs time and money

This is where open-source software can help

Contrail

I A research project funded by the European Commission (FP7 IP)I 11 partners in 6 countries

I Goal: build an advanced open-source Cloud platformI Open-source

I Built upon OpenNebulaI Maybe also OpenStack in the future

I Support for Cloud federationsI Aggregate multiple Clouds in a single federationI Public and private cloudsI Access the federation rather than any individual cloud

I Support for Service Level AgreementsI Quality of serviceI Quality of protection

I ConPaaS: a fully-featured Platform-as-a-Service environment

ConPaaS objectives

Goal: provide a fully-featured

PaaS environment for Contrail

I Broad range of functionalitiesI Web application hosting (static �les, PHP, Java, . . . )I Databases (SQL and NoSQL)I High-performance execution frameworks (MapReduce, BagsOfTasks)

I Fully integratedI Applications can compose any set of services together

I Easy to use but also very powerfulI Simple Web GUI + powerful command-line toolI Services are highly customizable

I Cutting-edge SLA enforcement technologiesI Elasticity and resource provisioning techniques to guarantee

performance at the lowest possible cost

I Platform-independentI Runs on Contrail but also other Clouds

ConPaaS ApplicationsA ConPaaS application is de�ned as a composition of multiple service

instances

I For example: web hosting service + MySQL database + logging

service (to store access logs)

PHP service

(using 1 or more

machine instances)

Logging service

(using 1 or more

machine instances)

End user

SQL data service

(using 1 or more

machine instances)

Current status

I Initial alpha release available at www.conpaas.euI Front-end + Web hosting service

I Public testbed availableI Sign up for free, try our technology!

I First full software release planned in March 2012

Future plans

I Allow users to deploy a multi-service application in one operationI Developers write high-level manifest �le which is translated into OVF

by ConPaaS

I Performance monitoring and automatic resource provisioningI Specify a performance SLA, let the system create/destroy VMs to

achieve your goals at the lowest possible cost

I Fault-toleranceI What happens if a ConPaaS VM crashes?

I Development toolsI Eclipse plugin. . .
