Not all virtual machines are the same

Not all virtual machines are the same

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.

Latency, the worst enemy for any Hybrid Cloud environment

Latency, the worst enemy for any Hybrid Cloud environment

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.

“On the fly” backup and restores without requiring intermediate storage

“On the fly” backup and restores without requiring intermediate storage

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.
