But there is more:
RDS: relational database
SimpleDB: non-relational database
CloudWatch: performance monitoring
AutoScale: automatic application scaling
CloudFront: content delivery service
etc.
These services are specic to Amazon Web services

4. Customer lock-in
If you use any of the fancy services from your Cloud provider
you lock yourself in
The pricing scheme may change
The Cloud may decide to stop business with you
The Cloud may go out of business
The Cloud may have outages
How do we move to a dierent hosting environment?
Find an alternative for all services you were using
Re-implement large parts of the application
This costs time and money

6. Contrail
A research project funded by the European Commission (FP7 IP)
11 partners in 6 countries
Goal: build an advanced open-source Cloud platform
Open-source
Built upon OpenNebula
Maybe also OpenStack in the future
Support for Cloud federations
Aggregate multiple Clouds in a single federation
Public and private clouds
Access the federation rather than any individual cloud
Support for Service Level Agreements
Quality of service
Quality of protection

7. ConPaaS objectives
Goal: provide a fully-featured
PaaS environment for Contrail
Broad range of functionalities
Web application hosting (static les, PHP, Java, . . . )
Databases (SQL and NoSQL)
High-performance execution frameworks (MapReduce, BagsOfTasks)
Fully integrated
Applications can compose any set of services together
Easy to use but also very powerful
Simple Web GUI + powerful command-line tool
Services are highly customizable
Cutting-edge SLA enforcement technologies
Elasticity and resource provisioning techniques to guarantee
performance at the lowest possible cost
Platform-independent
Runs on Contrail but also other Clouds

8. ConPaaS Applications
A ConPaaS application is dened as a composition of multiple service
instances
For example: web hosting service + MySQL database + logging
service (to store access logs)
End user
PHP service
(using 1 or more
machine instances)
Logging service SQL data service
(using 1 or more (using 1 or more
machine instances) machine instances)

16. Future plans
Allow users to deploy a multi-service application in one operation
Developers write high-level manifest le which is translated into OVF
by ConPaaS
Performance monitoring and automatic resource provisioning
Specify a performance SLA, let the system create/destroy VMs to
achieve your goals at the lowest possible cost
Fault-tolerance
What happens if a ConPaaS VM crashes?
