If you are building database solutions in Azure , using Azure SQL Database then you will know that you have a purchasing option decision to make. That being should you use a vCore model or DTU approach?
Azure SQL vCore vs DTU

Azure SQL Database Connectivity
Have you ever wondered how your connection from outside of Azure to your database is handled? It is important to understand that there is a difference between route(s) from when connecting inside to that of outside of Azure.
Azure SQL Database – Greatest and Least TSQL
Being in the cloud does have many benefits, from lower administration to fast scaling but another “side effect” of operating in Azure SQL Database is the cloud first nature of changes. By this I basically mean new features always get pushed to Azure first before the classic on-premises version so some gems come to light.
Azure SQL Database and Memory
There are many factors to consider when you are thinking about the move to Azure SQL Database (PaaS) – this could be single databases (provisioned compute or serverless) to elastic pools. Going through your head should be how many vCores do you want? What are the I/O requirements, do we need access to certain features like in-memory OLTP? But what about the memory requirements? This has always been a key requirement for SQL Server – those wonderful words – Min / Max memory settings.
How does this relate to Azure? Well it all depends on your vCore count and the generation of hardware we select during the build process.
There are currently 4 hardware generations ( each has its own purpose) :Gen4, Gen5, Fsv2-series and M-series. Each type has xGB per vCore up to a certain max. So it is important to remember this when sizing your workloads. (screen shot summarising is below) https://docs.microsoft.com/en-us/azure/azure-sql/database/service-tiers-vcore?tabs=azure-portal
So, for example I select a provisioned Azure SQL Database – 12 vCore on Gen 4 means I will have 84GB memory available for my workload.
Azure Defender for SQL
If you have been following me or generally topics around Azure SQL Database and security you would know that it is important to leverage Advanced Data Security (ADS) for Azure SQL Database, if you remember this meant having tools such as advanced threat protection, vulnerability scans at your finger tips.
