Oracle to Cassandra Migrations
Oracle has been the dominant relational database technology in the market for decades. As the benefits that a NoSQL database environment can provide becomes clearer, it’s easy to see that Oracle is unable to effectively handle the variety, velocity or volume of data growth that todays business applications demand. With Cassandra, you don’t have to risk your business availability with threats to downtime and you certainly don’t have to deal with the always growing operational costs that Oracle requires for hardware, software, maintenance, and support. Throw in the growing need for multi datacenter support and the fact that an Oracle envrionment is not elastic – meaning it cannot take advantage of the cloud and hybridized environments – and Cassandra has become a simple choice.
