Database Reference
In-Depth Information
Management costs and build costs are significantly reduced because the ODA comes preconfigured with interconnect
and storage, as well as a tuned OS. The ODA also includes the option to virtualize the appliance, which can result
in significant savings to the organization by providing a complete boxed solution for virtualizing applications and
the database.
Businesses and enterprises often struggle with deadlines, and by using a traditional model of deployment, which
includes procurement as part of the project budget, it is often very hard to provide the agility that is required for a
business to bring ideas to fruition quickly. A typical deployment cycle can range from 30 to 90 days, which can make a
product that requires a database harder to get to market. Figure

shows a typical deployment cycle in a traditional
system vs. that with an ODA, based on deployment experience with Oracle Real Application Clusters (RAC). This may
vary by the deployment maturity model of an organization.

Traditional server vs. ODA with RAC
The disparity between a traditional setup and the setup of an ODA is huge. It may differ based upon the practices and
processes implemented by an organization. Traditionally, the process to deploy hardware includes the following steps:
1.
Procurement of hardware
2.
Delivery of hardware
3.
Setup of hardware
4.
Network connectivity and switch setup
5.
OS setup and tuning
6.
Database software setup
7.
Best practices post setup
These steps are just some of the many required to get a system up and running, and may differ based on the
infrastructure model an organization uses. Organizations have always had the ability to pre-buy and pre-provision
infrastructure, as well as build a shared model to support the business. This can be cost effective in some cases,
but can also be problematic because continuous understanding of new business requirements is a must. Business
requirements drive the complexity of the infrastructure according to the availability model. Requirements can
drive the need to prepare an environment that can support various business initiatives and provide an on-demand
framework that allows faster provisioning. The ODA can be used as an enabler for a private cloud-based framework
or a simple provisioning model.
