It's Time to Replace Your Private Database Cloud
While the public cloud has dramatically reshaped the overall IT marketplace over the past few years, many enterprise customers have been more impacted by its on-premises cousin, the private database cloud. These new architectures allow companies to improve their agility and reduce their costs, consolidating multiple applications into a standardized resource pool, enhanced through custom-built automation and self-service UIs. As well as these clouds have worked out, as they age and become candidates for replacement, should most companies renew them, or replace them with something better? As with most things in the IT world, technological innovations quickly obsolete last year’s shiny new thing—custom-built private database clouds are no different. New on-premises public cloud solutions like Oracle Exadata Cloud at Customer, provide all the same benefits of private clouds, but with better pay-for-use economics, vendor-provided and maintained automation, and lower management costs.
It's useful to step back and take a look at what comprises a private database cloud. Based on our experiences dealing with enterprise customers, we observe the following key characteristics and why these characteristics are better served with Exadata Cloud at Customer (ExaCC) rather than a build-your-own private cloud.
|Private Cloud Characteristic||Exadata Cloud at Customer|
|Scalable--high levels of utilization||Key to scalability and high levels of utilization is the ability to online scale a service up and down. Exadata Cloud at Customer can grow from as little as 2 cores, up to 400 cores. You can run a single database service or deploy hundreds of database services. Memory can scale to multiple TeraBytes, and database storage to hundreds of TeraBytes. More importantly, Exadata can scale back down, with capacity following the overall demand of user workloads.|
|Accessible--IT users can self-provision||Simple UIs and APIs are accessible via a web browser or network connection allowing any authorized user to deploy a database via intelligent automation. No special knowledge is required.|
|Elastic--appearance of infinite capacity on demand||ExaCC is available in different shapes (sizes), allowing you to choose the system that best meets your needs. You can scale within those limits, and should you outgrow them, you will be able to scale compute and storage beyond what you originally bought (coming soon), providing the appearance of infinite capacity. Single-button deployment of read-mostly replica databases via Active Data Guard standby databases will enable further elasticity, not just within a data center, but across data centers.|
|Shared--Workloads multiplex and capacity pooled||Databases running in ExaCC share a common pool of resources, including CPU, memory, storage, and IO. Simple provisioning tools give administrators the control to share or dedicate these resources across their databases. Share a single pool for test and dev but create a different and dedicated pool for production.|
|Metered consumption||Perhaps the biggest advantage of on-premises cloud solutions over private clouds is the new innovative licensing mechanisms. ExaCC allows you to pay for your database licenses in a traditional manner (BYOL) or via a pay-for-use service where you pay only for what was used during any given hour. In addition, you have access to database AWR metrics that can be used to create customized billing and charge-back plans.|
|Physical security and access control||Having the ExaCC in your data center gives you physical control of sensitive data that may be subject to regulatory requirements. This is why customers choose private clouds over public clouds in the first place. Also, ExaCC provides security administrators control over access to the data and underlying infrastructure by operators and other staff. They can vet and approve all access as required.|
Hopefully, it is clear you can replace a private database cloud with Exadata Cloud at Customer, but why is that better than doing it yourself? Let's take a look at some of the drivers that will impact the cost of a private cloud:
|Cost Driver||Exadata Cloud at Customer||Complete Build Your Own||Integrate Third-Party Tools|
|Acquisition Cost for Private Cloud Functionality||Low (included with service)||High (when you include salaries of in-house development staff)||Medium (license and support fees to third parties add up)|
|Development and maintenance||Low (included with service)||High||Medium|
|Licensing||Yes||No--must use perpetual licenses||No--must use perpetual licenses|
|Public Cloud Integration/Migration||Easy||Difficult||Difficult|
|Compliance||Included||High—spend your own time and money||High—AoC still required for unique environments|
|Risk Management||Included||High—develop your own||Medium|
The trend from Private Cloud to Exadata Cloud at Customer is underway. One of the largest metals and mining companies in the world recently migrated 300 databases to a new private database cloud based on seven Exadata Cloud at Customer systems. They experienced 150% ROI and 40% performance increase. Database deployment time improved by 16x and overall DBA time spent managing the system and databases dropped by 70%. See why Constellation Research found Exadata Cloud at Customer to be the most complete on-premises cloud offering. Don't just renew your private cloud, replace it.
