Advantages and disadvantages of Oracle Exadata and Exalogic ____oracle

The advantages offered by Oracle Resilient Cloud and data warehousing are obvious, first of all, that a single vendor provides all the underlying components: Oracle's one-stop approach helps simplify licensing, support, upgrades, and consolidation, all handled by a single vendor. This may help to prevent the frequent prevarication between vendors on technical issues. It is easier to configure, upgrade, and consolidate with a single vendor, simplifying the contact and validation paths of these issues to a single portal for easy deployment.

Other benefits include optimizing performance, increasing fault tolerance, and rapid deployment. However, these advantages can also be translated into disadvantages. For example, a single vendor solution usually means that you are locked on the vendor platform, making it difficult to migrate to another vendor. As far as Exadata is concerned, it may not be so serious, just because the organization is likely to already have a commitment to run Oracle databases. On the other hand, Oracle databases installed on Exadata systems can be transferred to other hardware at any time, which eases the problem of single vendor lock-in if needed.

With the release of Exalogic, the single vendor model tends to be more serious simply because Oracle Exalogic locks out various Oracle technologies, from Funsion middleware to JRockit, HotSpot. In this case there is no direct competitor.

Other drawbacks include price (hardware and software licensing), high cost of supporting contracts, and periodic upgrades. A diverse solution, IT managers have more control over pricing, sizing, and other issues, but they will be forced to "integrate themselves" with multi-vendor solutions.

Because of the size of the processing, it is difficult to distinguish between competing solutions, especially those customized and non customizable components. However, some of the features of Exalogic and Exadata can be created using common rack blade systems, high-performance storage area networks, and other vendors to provide applications. Databases can be selected from a business database or open source database, and OLTP capabilities can be provided by software vendors.
