The release of Python 3.6 came with exciting functionalities. I want to speak about the feature called interpolated format string – f-strings for short- through this quick post. This new feature allows us to have a more readable, concise and even faster way of formatting string, in short words: pythonic code.

Working with os paths is a prevalent task, especially when working on a console application in Python. Recently, I had to add a change to an existing feature where it was mandatory to return the last modified directory on a specific target. In Python, we have the opportunity to count with different libraries; in this post, we are going to use glob.

Sometimes, our working habits could experiment some interesting changes, maybe forced by real needs or even simply for the valid desire to explore new ways to do some tasks.  I remember in the past, I used to install SQL Server Developer edition on my laptop f. Nonetheless, I have had to add other Databases such as PostgreSQL or MySQL mainly for proof of concepts.  Therefore, I realized how much time and resources I was spending through the conventional process of installing from scratch new Databases versions, which includes taking valuable resources from my laptop.  At this point, I was convinced of replacing old working styles concerning Databases at my dev environment.

As the title of this post indicates, the Database Migration Service (DMS) could experiment with problems in very rare cases with the capacity to start/create a service due to not having enough resources in a specific region. It is interesting to start explaining why the provisioned number of Virtual Machines (VM) could impact DMS. If we ask Why? The answer is simple: behind the scenes, the VMs represent the “workers” in charge of executing ALL the tasks required by the migration service of DMS.
