It is not uncommon to find a wide range of situations among our customers in terms of virtual machine performance with SQL Server. In many cases, we find situations where performance levels are far from ideal but, in general terms, virtual machines themselves are not to blame. What usually happens is that when we move SQL Server to a virtual machine, we become constrained by a maximum or limited amount of resources (CPU/ memory/ IO) that is significantly different to that of the physical machine.

Companies are increasingly choosing cloud services such as Azure or AWS that normally provide a flexible, profitable and scalable option to carry out their operations without the restrictions imposed by on-premise technologies.
Gradually, as storage gets faster and local SSD storage becomes more popular, etc. disk access times are significantly decreasing. In these regards, perhaps the best example are the SSDs Optane systems, notable for their much lower read/ write latencies than with traditional SSD’s, in addition to being directly connected through the PCIe bus: (more…)
In the last few years, we are increasingly finding more hybrid environments where some SQL Servers are being migrated to the Cloud. In these cases, other applications, services, ERPs or even SQL Server instances continue to be based OnPremise in the initial data center. This means that in the event of any connections between both environments, these will be restricted by bandwidth and higher latencies, as opposed to other connections that do not go across both environments.
In this entry, we will show you how to create bookmarks and a few different scenarios where they might be useful. Bookmarks are basically used to store the status of a specific report page including the filter selection and the visibility of the different objects, allowing the user to return to that same status by simply selecting the saved bookmark.
I’m sure that the most “senior” readers will remember the possibilities available in old SQL Server versions to do backups using named pipes. And by older versions, I mean “really old”, since this functionality was marked as obsolete in SQL Server 7 and, although it remained in SQL 2000, it was completely removed from SQL Server 2005 and later versions.
