Because Oracle Database XE provides a relatively encapsulated and uncomplicated installation along with an embedded Web listener and an Oracle Application Express front end, using it is a great way to start.

Feel like your Oracle-based project is starting to take off and you're going to need more processing power? This may be your answer.Īlthough you can come up with plenty of scenarios when considering how to best match the power of Oracle software with the flexibility, or elasticity, of Amazon EC2, by far the easiest, most visible, and most straightforward is simply implementing Oracle Database XE on a small EC2 instance. So you want to start a project or do some Oracle Application Express development on the cheap, using a single "server"? No problem. What's more, as with any other virtualization platform, you can very easily create your own replication, backup, and growth strategies, using virtualized server images rather than physical hardware with installed software. The details can be found here, but the gist is that you can pay as little as 10 cents per hour for a small instance (1.7GB of memory, one EC2 Compute Unit, 160GB of instance storage, and a 32-bit platform).

Moreover, because the hardware and network being used are dished out in small (and not-so-small), virtualized chunks, you can start with something akin to a single server and scale almost limitlessly without worrying about having to rent more space, buy hardware, or even install software best of all, you pay only for what you use. It is designed to make Web-scale computing easier for developers." Diving a little deeper, what Amazon is offering here is a chance to utilize its superior network, server hardware, and expertise and the ability for any subscriber to manage the entire architecture via Web services. Thus, the steps below will be of interest only to do-it-yourselfers and to people interested in how such templates are built-but knowing OTN readers, that could certainly be a lot of people! (See the Cloud Computing Center on OTN for more information.) Amazon EC2 OverviewĪmazon's Web site states, "Amazon Elastic Compute Cloud (Amazon EC2) is a Web service that provides resizable compute capacity in the cloud. 21, 2008, Oracle officially certifies/supports and licenses many of its products on Amazon Web Services-furthermore, Oracle now supplies free, prebuilt virtual machine templates (or Amazon Machine Images, as Amazon calls them) for Oracle Enterprise Linux, Oracle Database 10 g Express Edition (XE), all Oracle Database 11 geditions, Oracle Enterprise Manager, and various Oracle Fusion Middleware components. Because there are plenty of great resources for implementing Oracle grid-based systems on physical hardware, this article focuses on ways to implement Oracle technology on "clouds" of virtual servers such as those hosted by Amazon, via the Amazon Elastic Compute Cloud (EC2).Īs of Sept. Whether you are running an Oracle grid using Oracle Real Application Clusters on your own physical, low-cost blade servers or relying on hosted services such as Google Applications Engine or Amazon Web Services, tapping into the power and efficiency of computers configured to give you what you need when you need it, it is a complete paradigm shift from the "big iron" models of the past. Starting out as a twinkle in the eye of mainframe computers, today there is an array of options to choose from. The promise of utility-based computing has been a long time coming. Learn how to build and deploy Oracle Database 10g Express Edition virtual images in the Amazon Elastic Compute Cloud-the "do-it-yourself" way.
