Why Implement an Enterprise Database Cloud?
The foundation of many applications isthe underlying database that organizes, stores, retrieves, and protects application data. Throughout the application lifecyclewhether deploying new applications, enhancing existing ones, or testing updatesthere is almost always the need to create, reconfigure, tune, and ultimately delete databases. Ifthere are no available servers in the data center when a new database is required, IT must procure hardware platforms and integrate networking and storage components, designing inredundancy and room for growth. After installing and configuring hardware systems and components, administrators must then install, patch, and tune operating systems to support the necessary database and application infrastructure. Oracle Database and Oracle Real Applications Cluster (RAC) software releases must be installed and configured before database administrators can finally load data and enable access. The entire process can take days, weeks, andeven months, negatively impacting user productivity and delaying the pursuit of strategic business goals.
Over time as applications and supporting databases are implemented, the IT landscape can become dotted with multiple deployment silos, often over-configured to address peak workloads or recurring spikes in demand. Beyond the costs of acquiring hardware, software, storage and networking, there are ongoing maintenance and support costs that can proliferate as these server and storage components multiply and the complexity of the landscape increases. As a result of server sprawl and overprovisioning,traditional database deployments typically exhibit underutilized systems and evidence ofcost inefficiencies.
Shifting to a cloudbased delivery model dramatically changes database rollout and management, and by extension, the associated applications and business processes that leverage databases. Implementing a DBaaS cloud transitions organizations to an approach in which users can easily provision, consume, and comprehend thecosts of services they use, allowing Line of Business managers to predict IT budget requirements for new projects more accurately. Figure 1illustrates the steps in a traditional deployment model and contrasts this IT– driven process to the userdriven database cloud model.

Traditional database provisioning can take days or weeks compared to only minutes for users to self-provision.
Enterprises that deploy anenterprise database cloud typically benefit from:
 <   Ondemand, selfservice database provisioning, often using just a few intuitive browser screens for database creation. Provisioningis frequently reduced from days or weeks to minutes. 
<  Predefined database service templates or configuration definitions that allocate resources (from a consolidated and shared resource pool) to meet quality of service goals.

<  Fine-grained metering of database and resource usage that enables reporting of costs for a variety of metrics. Organizations can report back to users the costof the services that they consume or implement a full chargeback model in which users or departments pay for specific services they use.
<  Implementation of standard technologies and best practices to reduce costs and increase reliability.
These advantages contribute to lower operating costs, along with better and more flexible services. As a result, it reduces the tendency for parts of the business to “go it alone andcreate independent environments that don’t use standardized IT practices orscale well into the future.
Advantages ofthe Oracle Optimized Solution for Enterprise DatabaseCloud
The Oracle Optimized Solution forEnterprise Database Cloud provides a rapid and compelling solution to deploy adatabase cloud. The solution uses the Oracle SPARC SuperCluster, anengineered system that incorporates enhancements for Oracle Database deployments, and an existing ornewly installed implementation of Oracle Enterprise Manager 12c, which suppliesfunctionality for selfservice database provisioning andcloud management  via its Cloud Control feature. Together, the SPARC SuperCluster and Oracle Enterprise Manager 12c bring the following significant advantages to DBaaS cloud deployments.
Rapid Deployment of Database Cloud
As an engineered system, the SPARC SuperCluster reduces the effort required to plan, architect, build, optimize, and test a database cloud environment, greatly shortening the time it takes to deploy a cloud services delivery model into production. The SPARC SuperCluster is a highperformance andhighcapacity system that is optimized, prebuilt, and ready to configure for database services. Table 1 highlights how using this Oracle engineered system reduces the level ofadministrative effort and eliminates many timeconsuming steps that are otherwise necessary to construct a database cloud infrastructure from scratch.
EXAMPLE “FROM-SCRATCH” DATABASE CLOUD                                             
Ø  Hardware and Virtual Server Setup
o   Configure hardware, networks, storage from scratch
o   Configure domains (e.g., Oracle VM Server for SPARC)
o   Install operating system and patches (e.g., Oracle Solaris 11)
o   Create virtual servers (e.g., Oracle Solaris Zones) to support databases
Ø  Storage Setup
o   Allocate storage and optimize it to meet data security requirements and required database performance
o   Design and build in redundancy for network fabrics and for storage devices
Ø  Software Setup
o   Install and configure management software (e.g., Oracle Enterprise Manager 12c)
o   Use Oracle Enterprise Manager 12c to install Oracle Database 11g and Oracle Real Application Clusters (RAC) software
<  Hardware and Virtual Server Setup
ü  Done! Hardware pre-installed and configured
ü  Done! Oracle VM Server for SPARC domains configured
ü  Done! Oracle Solaris 11 installed and configured
ü  Supplied scripts create Oracle Solaris Zones to meet configuration requirements
<  Storage Setup
ü  Done! Oracle Automatic Storage Management provisioned on Oracle Exadata storage cells for optimal database performance
ü  Done! All SPARC SuperCluster storage and InfiniBand networks are preconfigured for high availability
<  Software Setup
ü  Only Oracle Enterprise Manager 12c discovery required
ü  Supplied scripts provision Oracle Database 11g and install Oracle Real Application Clusters (RAC) software
The SPARC SuperCluster allows enterprises to leverage adatabase cloud architecture and operating model that Oracle has already developed and tested, rather than requiring them to build the architecture from scratch. This is particularly valuableto organizations that are new to a cloud services paradigm.
Standardization of Database Services
The combination of SPARC SuperCluster and Oracle Enterprise Manager Cloud Control 12c enables standardized database services that feature consistent  availability, scalability, performance,  and chargeback attributes. After the infrastructure isinstalled, onsite staff use provided scripts to configure Oracle Solaris Zones on database domains to achieve the isolation of database workloads. In addition, administrators define a set of database service templates for useby selfservice users of the database cloud.
After the solution is installed andproperly configured, auser can select apre-defined service template and the management infrastructure then automatically provisions adatabase instancean approach that ensures the consistency of delivered services and frees up IT staff from timeconsuming and repetitive administrative tasks. The cloud deployment model allows development teams to receive access to services rapidly and easily while making sure delivered services conform to organizational standards for software stacks and hardware configurations. This improves supportability, reduces variation, and regulates the use of enterprise best practices to protect data integrity, increase availability, reduce administrative overhead, and minimize human error. IT staff can also more precisely manage resource allocations, enforcing quotas to control system and storage utilization so that business-critical databases get the resources that they demand.
Rapid Database Provisioning and Improved Agility
Once the database cloud is set up and ready for use, self-service users request and receive database services in a fraction of the time otherwise  required, enhancing  productivity,  business agility, and quality of service. Ina traditional model, aservice request typically follows anumber of steps that require extensive planning and manual setup. If the request occurs when resources are not readily available, ITmay need to purchase and provision new assets, which introduces significant additional delays. Selfservice provisioning eliminates the need for parts of the business to install their own databases that might deviate from IT standards for hardware, operating systems, database, and patch levels and increase overall risk and costs.
Flexibility to Support Varying Database Workloads
At the center of the Oracle Optimized Solution for Enterprise Database Cloud, the SPARC SuperCluster features configuration flexibility to meet a wide spectrum of database needs. Because of this flexibility, asingle system architecture can supply different degrees ofavailability and performance to address different enterprise workload requirements, including:
  <   Flexible resource allocation requirements, including varying allocations of compute threads, memory resources, network bandwidth, and storage capacities.
<  Database availability characteristics, including Oracle single instance, Oracle RAC 2-node, and Oracle RAC 4node configurations.
<  Temporary needs like those associated with development, testing, quality assurance, training, or similar functions. Once databases that support these workloads are no longer needed, they can be automatically deleted, making those system resources available to support other database service requests.
<  Intermittent spikes in database workloads, such as those that occur for seasonal transactions or at certain business intervals. The solution allows database environments to expand and contract by dynamically or even by programmatically allocating additional resources during these business cycles. With a traditional deployment of separate database servers, all servers need to be sized to support peak workload needs. In contrast, the database cloud solution allows sizing for typical workloads with amuch smaller amount of excess capacity held in reserve and allocated to meet periodic or occasional demand.
Access to different configuration choices isreadily available to end users through service templates and self– provisioning. The elastic nature of a database cloud allows the required services to be available onshort notice, aligningIT functionality more closely with changing business requirements
Lower Costs through Consolidation
Consolidation is a natural outcome of making the transition to an enterprise database cloud. Typical IT environments contain separate systems running Oracle Databases, each dedicated to different business initiatives, projects, or departments, with development (DEV), quality assurance (QAS), and production instances (PRD) often required for each. The result can be a complex, cumbersome landscape characterized by low utilization.
By taking advantage of integrated virtualization technologies in the solution, avariety ofDEV, QAS, and PRD database instances can be safely co-located. Consolidation on the SPARC SuperCluster eliminates the need to deploy, manage andsupport separate dedicated hardware and software environments for each projects development, testing, production, and failover environments. Consolidation helps to reduce total cost of ownership (TCO) through more effective management ofcapital acquisitions, improved utilization, and streamlined management. However, the benefits of deploying the Oracle Optimized Solution for Enterprise Database Cloud go far beyond consolidation and lower TCO—the solution simplifies the complexities of managing acloud infrastructure and provisioning database instances within it, reducing the time it takes to deploy database services and improving the quality of service.
Reduced Risk and Service Continuity
The Oracle Optimized Solution forEnterprise Database Cloud takes the guesswork and risk out of deploying
a database cloud environment. It is a comprehensive solution that is optimized, tested, and validated to reduce the risk of deployment problems, interoperability issues, and unplanned downtime.

The solution’s SPARC SuperCluster system features full builtin redundancyfrom  compute nodes to storage, network switches to network interface cards (NICs), and power distribution units (PDUs) to power suppliesto provide continuous availability for missioncritical databases. Oracle RAC enables transparent database deployment across all servers in the SPARC SuperCluster system, providing database fault tolerance in the event of hardware failures or planned outages.
