On-premises databases were overprovisioned for performance. Cloud databases are overprovisioned for a different reason: unpredictable pricing. This article explains the real cost.
Overprovisioning: The Curse Of The Cloud
Tag: Databases
Databases are the systems of record at the heart of the enterprise. They were designed for correctness, durability, and human-paced interaction – not for continuous, machine-driven access patterns.
As workloads evolve, the database remains the point of truth… but the assumptions around how it is accessed are starting to break.
The Battle For Your Databases
AWS, Azure and GCP are competing hard for enterprise databases. This article explains why mission-critical RDBMS workloads are the prize and what that means for DBAs.
The Public Cloud: The Hotel For Your Applications
The public cloud is like a hotel – flexible and convenient but shared infrastructure. This article explains what that model really means for enterprise databases.

flashdba returns from retirement to ask the question nobody in the cloud conversation was asking: when 75% of databases move to the cloud, what actually happens to performance?
New Installation Cookbook: Oracle Linux 6.7 with Oracle 11.2.0.4 RAC
I've updated my install cookbooks page to include a new cookbook for installation of Oracle 11.2.0.4 Real Application Clusters on Oracle Linux 6.7. This is also the first one I've published since I left the employment of Violin Memory to work for Kaminario, so this install uses a Kaminario K2 All Flash Array.

When I wrote that first post I was about to start my summer holidays, so I'm afraid … Continue reading Oracle’s ASM Filter Driver Revisited
The Great Hypervisor Bake-off: VMware ESX vs Oracle VM
This is a very simple post to show the results of some recent testing that Tom and I ran using Oracle SLOB on Violin to determine the impact of using virtualization. But before we get to that, I am duty bound to write a paragraph of text featuring lots of long sentences peppered with industry buzz … Continue reading The Great Hypervisor Bake-off: VMware ESX vs Oracle VM
ASM Rebalance Too Slow? 3 Tips To Improve Rebalance Times
I've run into a few customers recently who have had problems with their ASM rebalance operations running too slowly. Surprisingly, there were some simple concepts being overlooked - and once these were understood, the rebalance times were dramatically improved. For that reason, I'm documenting the solutions here... I hope that somebody, somewhere benefits... 1. Don't … Continue reading ASM Rebalance Too Slow? 3 Tips To Improve Rebalance Times

A quick post to say that this week, on Thursday 26th, I will be giving a talk (in English!) on the subject of Flash for DBAs (and architects, designers, developers, managers etc) at the Paris Oracle Meetup: Flash for DBAs: A new technology is sweeping the world of storage. Flash, a type of non-volatile memory, is … Continue reading Paris Oracle Meetup (Jeudi 26 Mars 2015 @ 7pm)
