Storage Location and Storage Classes + Cloud Shell Exercises


There is a slight difference from what we can see on the lecture and what we can see on GCP Console right now. On the video, you see Mattias speaking and explaining about the location of the data, where that storage area will be allocated for you to create your buckets, together with the storage classes, at that time, only Nearline and Coldline were available.

You will see that the screen is horizontally sliced when you see the "Choose where to store your data" which refers to the location of the data or "a permanent choice which defines the geographic placement of your data and affects cost, performance, and availability" and the "Choose a default storage class for your data" which defines the way your data will be stored and further accessed when you need, as that, "a storage class sets costs for storage, retrieval, and operations. Pick a default storage class based on how long you plan to store your data and how often it will be accessed".

On the screen you can see a definition for the location of data, or, if the bucket is Regional, Dual-region, or even Multi-regional, and what is your choice for the storage class, being them Standard, Nearline, Coldline and Archive.

Hello Bianchi and Cloud Guru’s, Sorry to bug you with this but I am having a minor issue and cannot find a solution online. After making sure im in the right Project ID whenever I try to rm a file I get a new line starting with ">". Then I noticed I was deleting a pdf file, I added a text file then I was able to delete it. My question is why can’t I delete a pdf file through cloudShell? or what is the best way to do so?

Hello Ahmed,

I’m not sure I understood correctly your question. But, is it related to upload and remove a *.pdf file?

wagnerbianchijr@cloudshell:~ (acloudguruproject)$ gsutil ls  
wagnerbianchijr@cloudshell:~ (acloudguruproject)$ gsutil mb gs://mytestbucket-1029834718092  
Creating gs://mytestbucket-1029834718092/...

Using the console, I uploaded a *.pdf file and checked again.

wagnerbianchijr@cloudshell:~ (acloudguruproject)$ gsutil ls gs://mytestbucket-1029834718092/**  
wagnerbianchijr@cloudshell:~ (acloudguruproject)$ gsutil rm gs://mytestbucket-1029834718092/Ze0uno4rI=.pdf      
Removing gs://mytestbucket-1029834718092/Ze0uno4rI=.pdf...  
/ [1 objects]  
Operation completed over 1 objects.    
wagnerbianchijr@cloudshell:~ (acloudguruproject)$ gsutil ls gs://mytestbucket-1029834718092/**

wagnerbianchijr@cloudshell:~ (acloudguruproject)$ gsutil rb gs://mytestbucket-1029834718092

Did I understand it correctly? Can you share the history of commands you were running on your Cloud Shell instance?
