Oracle Database 12c is becoming the ultimate foundation for database clouds, says Oracle Executive Vice President Andy Mendelsohn.
New capabilities for database security and mission-critical cloud computing services in Oracle Database 12c will give customers confidence to move larger workloads to the cloud, said Oracle Executive Vice President of Database Server Technologies Andy Mendelsohn at Oracle OpenWorld 2015 on Monday, October 26. He illustrated how Oracle Database 12c is becoming the ultimate foundation for database clouds, and gave attendees a peek into new features planned for Oracle Database 12c Release 2, which has already begun its public beta.
Following on statements by Oracle Executive Chairman and CTO Larry Ellison on Sunday, Mendelsohn said Oracle customers have a distinct advantage when it comes to working across on-premises and cloud-based databases. “Other clouds, like Amazon, have no story on premises,” he said. “But a lot of you will have been using Oracle Database in your data centers for many years and, like Larry said, you are not going to move everything up to the cloud next week or even next year,” said Mendelsohn. “This transition will happen over the next 10 or 20 years.”
The big advantage for Oracle customers, he said, is that all the skills that developers and DBAs have used on premises carry over easily to Oracle Cloud. “All those applications you’ve written over the years, they just work on Oracle Cloud,” said Mendelsohn.

He also pointed to recently announced features in Oracle Enterprise Manager12c that allow customers to manage all their databases—on premises and in the cloud—using a single screen. “This is a big differentiator for Oracle versus the classic Amazon-type cloud service.”
One new service in Oracle Cloud, called Oracle Database Exadata Cloud Service, “is a real milestone in the cloud,” said Mendelsohn. “It’s just like Oracle Exadata on premises, it can run all your workloads from your departmental systems up to your most demanding, mission-critical OLTP systems and giant data warehouses,” he said. With this, said Mendelsohn, customers can scale up to hundreds of cores and terabytes of data in the cloud.
Some people are still hesitant to move data to the cloud because of security concerns, but that will be overcome soon, he said. “We’re convinced that over the next few years, security is going to be the main reason people move to public cloud,” said Mendelsohn, because vendors like Oracle can provide vastly better security than most customers can on premises.
Oracle Database 12c Release 2 includes many other planned features to simplify the journey to the cloud.

Mendelsohn said at this time last year 87 customers were running Oracle Database schemas in Oracle Cloud. That number has changed dramatically. “Over the last year we’ve grown to thousands of customers using our database cloud and we’ve grown to what we think is the broadest offering on the public cloud.” Oracle offers database services that appeal to every level of user, Mendelsohn said, from entry-level developer, up through departmental and small business capabilities, all the way up to enterprises using high-performance services like Oracle Exadata Cloud Service, “which can run your most demanding workloads,” he said.
Mendelsohn believes a unique feature of Oracle Database 12c, called Oracle Multitenant, will help customers drive down the cost of managing databases and allow them to easily move databases across a company, or into the cloud. Oracle Multitenant enables database managers to create a container database in which they can run up to 252 pluggable databases. “You can take what you used to think of as separate databases and manage them all with a single container database,” he said. “A single database administrator can manage them as one,” he said. “Now you can scale the administrator to manage a large cloud of databases.”
Mendelsohn wants customers to think of Oracle Multitenant as a way of becoming more agile. He said many customers are happily using Oracle Multitenant, including many who are delivering talks at Oracle OpenWorld, such as GE and Cisco Systems.
Important new features are planned to be added to Oracle Multitenant in Oracle Database 12c Release 2. While customers can currently manage 252 pluggable databases in a single container database, Oracle Database 12c Release 2 significantly increases the number of databases in a single container. “This is ideal for many use cases, including SaaS providers, where you might be managing millions of databases,” said Mendelsohn.
Oracle Database 12c Release 2 includes many other planned features to simplify the journey to the cloud, said Mendelsohn. Much of his team’s effort, he said, has been focused on helping the database developer. “We’ve done a lot of work on open source drivers for Oracle Database 12c Release 2, and new work on application continuity.”
Planned updates include new capabilities for developers working in Java and C, and improved compatibility with popular REST services, “Point at database objects and automatically create REST procedures,” he said. Oracle Database 12c Release 2 contains thoughtful updates such as enhanced database object identifiers. “It sounds simple, but it's actually a big deal for customers, especially if you’re naming objects in a language like Mandarin, where each character takes several bytes,” he said. “Again, we focused on making things easier for database developers in big and small ways,” he said.
