Amazon Aurora Serverless (PostgreSQL compatibility)

By Franck Pachot

.
I’ve written a blog post about serverless databases and here is an example of Amazon RDS Aurora PostgreSQL in serverless mode:

Amazon or AWS services?

By Franck Pachot

.
When I’m writing about a product I like to be precise about the name, the upper and lower case, and even more: do you know that was taking special care of writing Oracle 12cR2 before then non-italic came with 18c? And that’s also the reason I’m not writing a lot about VMware as it takes me 5 minutes to put the uppercase right </p />

Amazon DynamoDB: a r(el)ational Glossary

By Franck Pachot

.
There are many NoSQL databases. And, because SQL is an ISO standard, “No SQL” also means “No Standard”. Many have a similar API and similar objects, but with completely different names. Today, NoSQL databases are used as an additional datastore for some well-defined use cases for which a hashed key-value store fits better than a relational table. And it quickly became “Not Only SQL” as it is complementary to RDBMS databases using SQL. But at the origin, the idea was to replace the RDBMS databases, refusing the SQL API, and then inventing a “No SQL” data store. When you want to replace something rather than proposing something new, you often adopt the same language to make it look similar. And this why, in my opinion we find some relational database terms like “Table” and “Index”. But they have a different meaning. Here is a dictionary where I try to explain the DynamoDB artifacts and differentiate from their Relational and SQL meaning.

Introducing packer: building immutable infrastructure in the cloud

After having spent a bit of time with Packer to create Vagrant base boxes it was time to focus on the cloud. I have referenced Packer multiple times in my cloud talks as a popular way to create immutable infrastructure and/or custom images, and I wanted to share how you could potentially make use of the technology

Be aware that this is a post about cloud technology. If you are following along, be aware that you will incur cost.

Data virtualization on SQL Server with Redgate SQL Clone

By Franck Pachot

.
In the previous blog post I’ve installed SQL Server on the Oracle Cloud. My goal was actually to have a look at Redgate SQL Clone, a product that automates thin cloning. The SQL Server from the Oracle marketplace is ok for SQL Clone prerequisites. There’s a little difference in .NET Framework version (I have 4.6 where 4.7.2 or later is required but that’s fine – if it was not an update would be easy anyway).

SQL Server on Oracle Cloud

You can create a VM with SQL Server running in the Oracle Cloud. This is easy with a few clicks on the marketplace:

Oracle ADB: rename the service_name connect_data

By Franck Pachot

.
Since Aug. 4, 2020 we have the possibility to rename an Autonomous Database (ATP, ADW or AJD – the latest JSON database) on shared Exadata infrastructure (what was called ‘serverless’ last year which is a PDB in a public CDB). As the PDB name is internal, we reference the ADB with its database name is actually a part of the service name.

I have an ATP database that I’ve created in the Oracle Cloud Free Tier a few months ago.
I have downloaded the region and instance wallet to be used by client connections:

A Serverless Standby Database called Oracle Autonomous Data Guard

By Franck Pachot

.
Announced by Larry Ellison last week, here it is: the Autonomous Data Guard. You can try it, unfortunately not on the Free Tier.
First you create an Autonomous Database (ATP or ADW) and then you enable Autonomous Data Guard.

DBPod – le podcast Bases de Données

By Franck Pachot

.
J’essaie quelque chose de nouveau. Je publie beaucoup en anglais (blog, articles, présentations) mais cette fois quelque chose de 100% francophone. En sortant du confinement, on reprend les transports (train, voiture,…) et c’est l’occasion de se détendre en musique mais aussi de s’informer avec des podcasts. J’ai l’impression que c’est un format qui a de l’avenir: moins contraignant que regarder une video ou ou lire un article ou une newsletter. Alors je teste une plateforme 100% gratuite: Anchor (c’est un peu le ‘Medium’ du Podcast).
