By | Cloud, Database Administration & Monitoring | No Comments

A couple of weeks ago, I wrote up about my first immersion into the SQL Server managed instances (SQLMIs), a new deployment model of Azure SQL Database which provides near 100% compatibility with the latest SQL Server on-premises Database Engine. In the previous blog post, to test a connection to this new service, I installed an Azure virtual machine on the same VNET (172.16.0.0/16) including SQL Server management studio.

ATP vs ADW – the Autonomous Database lockdown profiles

By | Cloud, Oracle | No Comments

By Franck Pachot . The Oracle database has always distinguished two types of workloads: transactional (OLTP) and datawarehouse (VLDB, DWH, DSS, BI, analytics).

Now, with In-Memory Column Store, Smart…

Introducing SQL managed instances on Azure

By | Cloud, Database Administration & Monitoring | No Comments

I never wrote about data platform solutions on Azure so far. The fact is in Switzerland we’re definitely late about the Cloud adoption and Azure data platform solutions.
