Oracle Database Appliance vs Oracle Cloud Infrastructure

By | Cloud, Database Administration & Monitoring, Database management, Development & Performance, Hardware & Storage, Operation systems, Oracle | No Comments

Introduction Oracle Database Appliances are very popular these days. And not only among new customers for this kind of engineered systems. Almost all customers already using old generation ODAs are renewing their infrastructure by choosing again ODAs, meaning that the solution is good enough and probably better than anything else. But now, public clouds are a real alternative to on-premise servers, and Oracle Cloud Infrastructure is a solid competitor vs Amazon and Azure public clouds….

YCSB (NoSQL benchmark) on Oracle Database

By | Cloud, Database Administration & Monitoring, NoSQL | 7 Comments

By Franck Pachot . The NoSQL technologies emerged for Big Data workloads where eventual consistency is acceptable and scaling out to multiple server nodes is an easy answer to increase throughput. With cloud services rising, those key-value document datastores started to be used by the web-scale companies for some transactional processing workloads as well. The solutions can provide high performance and easy partitioning capabilities thanks to the very simple API of NoSQL. Each table or…

Amazon Aurora Serverless (PostgreSQL compatibility)

By | AWS, Cloud | No Comments

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: When I’ve created the instance (15:55 – CloudWatch is GMT+2 but event log is UTC), it started with 0 capacity unit (18:03), which means that it was paused (you pay for storage only). Then I connected and the instance was resumed (18:19) to its maximum capacity unit (4 here). And…

Amazon or AWS services?

By | AWS, Cloud | No Comments

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 😀 You may have seen that many Amazon…

What is Object Storage?

By | AWS, Cloud, Oracle | No Comments

By Franck Pachot . I’ve always been working with databases. Before the cloud era, the most abstract term was “data”. A variable in memory is data. A file is data. A block of disk contains data. We often created a ‘/data’ directory to put everything that is not binaries and configuration files. I’ll always remember when I did that while working in Dakar. My colleagues were laughing for minutes – my Senegalese followers will understand…

Amazon DynamoDB: a r(el)ational Glossary

By | AWS, Cloud | No Comments

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…

Data virtualization on SQL Server with Redgate SQL Clone

By | Cloud, DevOps, SQL Server | No Comments

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…

By | Cloud, Oracle, SQL Server | No Comments
