Hyperscalers have solved cloud infrastructure for most workloads. High-performance RDBMS remains the exception – the gap between cloud promises and database reality is still real.
The Biggest Gap In The Clouds? High Performance RDBMS
Category: Storage
Storage is the foundation on which database performance is built. Latency, throughput, and consistency at this layer directly shape how systems behave under load.
While often abstracted away in modern architectures, storage characteristics continue to define the limits of what databases can achieve – especially as workloads become more demanding and less predictable.
Cloud Compromises: Constrained and Optimized CPUs
Not all cloud vCPUs are equal. This article explains how constrained and optimised CPU configurations affect enterprise database performance in ways the spec sheet doesn’t reveal.
Overprovisioning: The Curse Of The Cloud
On-premises databases were overprovisioned for performance. Cloud databases are overprovisioned for a different reason: unpredictable pricing. This article explains the real cost.
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.
Don’t Call It A Comeback
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?
The Final Post: Hardware Is Dead
Well, my friends, this is it. The time has come to retire the flashdba jersey after more than seven years of fun and frolics. In part one of this post, I looked back at my time in the All-Flash storage industry and marvelled at the crazy, Game of Thrones-style chaos that saw so many companies arrive, … Continue reading The Final Post: Hardware Is Dead
Flash Debrief: The End (part 1)
Seven years ago this month, I created a blog and online presence called flashdba to mark the start of my journey away from Oracle databases (and DBAing) into the newly-born All-Flash Storage industry. Six years ago this month, I posted the first in what transpired to be a very long blog series attempting to explain the … Continue reading Flash Debrief: The End (part 1)
Oracle ASM and Thin Provisioning – How To Reclaim Space
It came to my attention last November that I had crossed the one year anniversary since my last post on flashdba.com. I was so surprised that I immediately decided to write a new post, which took another three months. There are reasons why I'm no longer posting technical blogs about databases and flash, but I'll … Continue reading Oracle ASM and Thin Provisioning – How To Reclaim Space
All Flash Arrays: Scale Up vs Scale Out (Part 2)
In the first post on the subject of Scale Up versus Scale Out, we looked at the reasons why scalability is a key requirement for storage platforms, as well as discussing the limits of Scale Up only architectures, i.e. systems where more capacity is added to the same fixed number of controllers. In this article, … Continue reading All Flash Arrays: Scale Up vs Scale Out (Part 2)
All Flash Arrays: Scale Up vs Scale Out (Part 1)
Imagine you want to buy some more storage for your laptop - let's say an external USB drive for backups. What are the fundamental questions you need to ask before you get down to the thorny issue of price? Typically, there is only one key question: How much capacity do I need? Of course there … Continue reading All Flash Arrays: Scale Up vs Scale Out (Part 1)
