Today Steve Jones has a few thoughts on the complexity and cumbersome nature of database development.
Although Azure is the obvious Cloud service to host SQL Server, Amazon Relational Database Service (RDS) for SQL Server is a good choice when your organisation uses AWS. RDS deals with maintenance and monitoring, and supports the use of PowerShell to automate routine tasks. What if a script needs to be triggered by an unscheduled event? Even in this case, RDS can be configured to run scripts to react when something like a failover happens. Laerte Junior shows how easy it is to set up Lambda functions and some PowerShell scripts to automatically synchronise agent jobs after a failover.
One of the most glib generalisations you can make about development work is to say that code should be liberally commented, or conversely that it should never be commented. As always, the truth is more complicated. There are many different types of comment and some types are best treated firmly with the delete key, where others are to be cherished and maintained assiduously. Even though it is hard to find two developers who agree on the topic of commenting, Michael Sorens warily sketches out the issues and the battleground.
