2. Infrastructure clouds And next generation
Software Engineering
 Their role
 Infrastructure clouds are expected to play an important role in the next generation Software Engineering but
currently there are some drawbacks
 The drawback : Lack of
 service elasticity
 quality of service
 admission control
 The deployment of complex multi-tier applications on top of IaaS infrastructures requires to
provide the IaaS platforms with an extra service layer that provides advanced service
management functionality.

3. How cloud supports Software
Engineering?
 Adaptability and scalability
 Availability and fault-tolerance
 Portability and reusability
 Security
 Cost and sustainability

4. Different Could Provisioning models
 Infrastructure as a Sercvice (IaaS)
 Platform as a Service (Paas)
 Software as a Service (SaaS)
 Everything as a Service (XaaS)

5. The Most Popular And mature
technology?
 Currently, the most popular and mature technology are the IaaS clouds
 boosted by the proliferation of many commercial providers
 Amazon EC2
 Rightscale
 GoGrid
 Rackspace,
 ElasticHosts
 etc
 different technologies for private cloud management
 OpenNebula6
 Eucalyptus7
 OpenStack VMware vCenter

6. A service-oriented cloud architecture

7. A service-oriented cloud architecture
Provides the following benefits:
 Automated service management
 Optimized service provision
 Brokering mechanisms
 Dynamic service provision in cloud infrastructures
 Advanced service SLA and elasticity management
 Support for multi-cloud service deployment

8. Research behind the challenges
 Service life-cycle management and admission control
 Service SLA and elasticity management
 Cloud brokering

9. Conclusions
 Cloud computing is playing an important role in the provision of flexible, elastic
and on-demand IT environments in which areas such as Software Engineering
can flourish.
 The abstraction between layers needs to be strengthened. As of IaaS, the
current providers need to provide an interface for translating requirements
from PaaS and SaaS.
 Considering a non-monolithic model, a user from the upper layers shouldn’t
need to define the deployment of an application by terms of machines and
networks, but by performance, budget and other operative parameters
instead.
 there is a need of developing standard methods for advanced service SLA
and elasticity management. This, in conjunction with a multi-cloud service
placement at IaaS broker level, will allow an efficient scalable deployment of
any application
