Oracle Database Cloud (DBaaS) Performance - Part 1 - CPU

After having looked at the performance consistency provided by the Oracle Database Cloud offering in the previous series, I'll focus here on the raw performance figures I've measured during my tests, starting with the CPU related performance findings.

One of the first surprises is related to the fact that Oracle uses a unit called "OCPU" to specify the CPU capacity provided, which is explained here:

Azure and Oracle Cloud – My First Time

Below talks about my experience trying out Azure and Oracle cloud for the very first time (and at the same time).


So last night I tried for the very 1st time the Azure and Oracle Cloud. Here, I just like to share my experience. BTW I am a big fan of DigitalOcean because of its user friendly interface, very fast to setup (end to end 2 minutes w/ few button clicks), and fantastic community and HOWTOs (https://www.digitalocean.com/community/). If I have to choose a cloud dev environment provider I would still use DigitalOcean.

Now, being a newbie on both these platforms. I’m looking for a similar experience as DigitalOcean.

The cloud experience comparison is broken down to 3 categories:

Oracle Database Cloud (DBaaS) Performance Consistency - Part 7

This part of the series is supposed to cover the results of I/O related tests performed on the Amazon RDS Oracle cloud instance.

As mentioned in the previous part of this series I've only used the "General Purpose SSD" storage type since the "Provisioned IOPS" storage was simply to expensive to me and it wasn't possible to get a trial license for that storage type.

Approximate Aggregate Transformation (AAT)

There are situations where approximate results are superior than exact results. Typically, this is the case when two conditions are met. First, when the time and/or resources needed to produce exact results are much higher than for approximate results. Second, when approximate results are good enough. Approximate results are for example superior in case of exploratory queries or when results are displayed in a visual manner that doesn’t convey small differences.

Oracle Database Cloud (DBaaS) Performance Consistency - Part 6

Oracle Database Cloud (DBaaS) Performance Consistency - Part 5

This is the fifth part of this installment, and before coming to comparisons to other cloud providers, in this part I show the results of the read-only test that I've already described in part three of this series, but repeated at a later point in time. The test setup was identical and can be checked in the mentioned previous part.

The reason for running the test again was the fact that I was informed during the first test run that the zone that my Oracle Cloud domain was assigned to was temporarily overloaded, which I also noticed since I wasn't able to create new services for some time.

Hence I decided to repeat the tests after it was confirmed that the issue got resolved.
