Managed Instancesin Azure SQL Database offer only the vCore-basedpurchasing model.DTU and eDTUThe performance of SQL Database is based on DTU.According to Microsoft, a DTU is a unit of measure of the resources that areguaranteed to be available to a single Azure SQL Database at a specificperformance level within a single database tier. A DTU combines CPU,memory, data I/O, and transaction I/O.Databases can be placed into anelastic poolon a SQL Database serverthat shares a pool of resources among those databases. The shared pool ofresources are measured byelastic Database transition units(eDTU).The advantages of an elastic pool are:oThey are scaled automatically.oThey provide predictable costs.They are widely used forvaryingandunpredictable usage patterns.Determining DTUs for WorkloadsIf you are planning to move your on-premises Databases to Azure SQLDatabase, Azure provides aDTU Calculatorto find the approximate DTUsrequired for setting up the database.For an existing Azure Database, you can useSQL Data query performanceinsight. This Query performance insight provides a deeper insight into theresource consumption (DTU's) of Database, the top queries byCPU/Duration/Execution count, which can potentially be tuned for improvedperformance.1.To create a MySQL Database with given charset and collation rulesaz mysql db create --resource-group testgroup --server-name testsvr --nametestdb --charset {valid_charset} --collation {valid_collation}2.To delete a DB:az mysql db delete -g testgroup -s testsvr -n testdb3.List all DB in a server:

CDN WorkflowYou have seen what CDN is and how to set it up. But how does it work? Let'sfind out.1.A user (John) requests a file (file1) using a URL,<endpointname>.azureedge.net.2.DNS routes the request to the POP location, which is geographically closestto the user.3.Now, consider that the edge servers does not have the requested file in theircache memory, then it requests the needed file from theorigin.
