IT Perspective for DeveloperCapital Expenditure (CapEx) for development environ.
could be highAcquisition of hardware, software, necessary services, etc.HW, SW upgrades, back up/restore of development
environ., etc.Operational Expenditure (OpEx) for support, etc. Development environ. utilization low
IT Perspective for DCCapEx for the data center (DC) is very high
Scalability, availability, and DR require redundant HW + SWOpEx can also be high
App administrators, DBA, storage administrators are expensive
Data center power usage and cooling has also become a big issue
Data center resource utilization is typically lowRedundant HW + SW usually sit idle for a long time
Enterprise Perspective

Cloud Computing Characteristics:Measured Service
Cloud Computing Service Models:Software-as-a-Service (SaaS)Consumer uses the provider’s applications running on a cloud.
Cloud Computing Service Models:Platform-as-a-Service (PaaS)Consumer uses the programming languages and tools
supported by the provider to create and deploy applications or deploy acquired applications
Elastic Beanstalk (beta)
Cloud Computing Service Models:Infrastructure-as-a-Service (IaaS)Consumer uses provider’s processing, storage, networks,
and other fundamental computing resources to deploy and run arbitrary software, which can include operating systems and applications.
Elastic Compute Cloud (EC2)
Cloud Computing Deployment Models• Private cloud. The cloud infrastructure is operated solely for an
organization. It may be managed by the organization or a third party and may exist on premise or off premise.
• Community cloud. The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns.
• Public cloud. The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
• Hybrid cloud. The cloud infrastructure is a composition of two or more clouds that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability.
