NIST Definition of Cloud Computing

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

This cloud model promotes availability and is composed of:

Public Clouds:• Lower upfront costs• Economies of scale• Simpler to manage• OpEx

Private Cloud:• Lower total costs• Greater control over security,

compliance & quality of service• Easier integration• CapEx & OpEx

Both offer:• High efficiency• High availability• Elastic capacity

• Used by multiple tenants on a shared basis

• Hosted and managed by cloud service provider

• Limited variety of offerings

• Exclusively used by a single organization

• Controlled and managed byin-house IT

• Large number of applications

Oracle Private PaaS:What, Why and How

© 2010 Oracle 16

Why Enterprise Private PaaS

• Why Cloud?- Agility and speed- Efficiency and cost

• Why Private?- Security- Compliance- Control (particularly over QoS)- Easiest evolution of existing

expertise and practices

• Why Platform?- Maximizes component re-use- Minimizes hand coding- Maximizes flexibility and control

Evolving From Silos to GridFrom Physical to Virtual

• Physical, dedicated silos

• Sized for peak load

• Difficult to scale

• Expensive to manage

• Virtualized, shared resources

• Improved utilization

• Scale as needed

• Efficient to manage

Elastic Scalabilitywith Grid Computing


NetWorkload

If utilization too high,increase capacity

• Pay-as-you-go scale-out- Lower upfront CapEx and

ongoing OpEx- Green footprint

• Rightsized capacity planning- Smaller, standard machines

running at higher utilization

• Defer equipment procurement- Exploit advances in hardware

price-performance and energy efficiency



• World-class clustering at all levels: database, middleware, storage

• Add/Remove nodes on-demand

• Scale out as workload increases

Oracle IT: Oracle DevelopmentSelf-Service Private Cloud

• Implementation Overview:- Scope/Scale - Over 2600 physical servers with over 6000 Virtual

Servers used by over 3500 developers- Activations – Processing over 70 jobs per day, this translates into

over 45,000 jobs processed supporting production and test requirements.

- Utilization – Rates on these servers averages 80% 7 days a week and can reach 90% during peak times.

• Results/Benefits: - Increase in development productivity- Self-Service system for creation of development environments- Cleaner code lines as environments are created quickly for more

thorough testing/validation.- Physical Server/Environmental Reduction by 75%- Server/Apps Deployment reduced by 80%

Oracle IT: Oracle UniversityDynamic Provisioning with Grid Computing

• Education Services

• 2,300 environments automaticallyprovisioned weekly

• 1/10th the hardware

• CPU utilization increased from 7% to 73%

• Floor space reduced 50%

• Power consumption reduced 40%

• Servers: Administrator ratio increased 10X

• Revenue/Server increased 10X
