In this episode of Google Cloud Weekly, we are going to explore what really happens when you delete something from Google Cloud. Is it really deleted, and how can you be sure? Also, addictive mobile games make the move to Google Cloud. Let’s take a closer look.

Deleting your data in Google Cloud Platform

When you delete something from any computing device, especially sensitive data, you want to be sure that it is truly and definitely erased from existence. However, that’s not the case if you don’t remove data correctly. For example, if you just deleted something from a hard drive, it is often possible to still recover that data that you don’t want slipping out. That’s not a good thing.
So when you delete something from Google Cloud, how can you be confident that it is truly erased, especially since you don’t control the hard drives yourself?
Google recently detailed the process of handling deletion requests, and how they make sure that your stuff is truly out of here! Now since there are many GCP services, some processes are different depending on what it is you are deleting. For example, the process for deleting a project will be different than deleting a cloud storage object.
So how does it work? After receiving a deletion request, services which have a ‘grace period’ in case you change your mind (such as projects) will lock away the data, making it inaccessible to other services, but still giving you the ability to get it back if you change your mind.

Once any grace period expires, data is then deleted using either a mark and sweep garbage collection or cryptographic erasure. These are methods to make absolutely certain that your data is gone and cannot be recovered later.
But wait, there’s more! Once the physical disk your data was on reaches end of life, it is fully wiped again, and even crushed or shredded if necessary. You can’t pull data from a drive once it’s been turned into confetti, right?

The point of all of this is that when you delete something from Google Cloud, you can be rest assured that it is without a doubt, 100% gone. The entire process from start to finish is explained in Google’s deep dive article, which you can find here.

Candy Crush is moving to Google Cloud

Mobile games these days sure are addictive! Speaking of which, Candy Crush is migrating their game resources to Google Cloud. King, which is Candy Crush’s parent company, currently runs one of Europe’s largest Hadoop cluster to manage tens of petabytes of data generated by players of its games. Now what’s important is that the ability to quickly analyze this massive amount of data is what allows game companies to make their games just that much more addicting.

As a result, King has been evaluating whether continuing to run Hadoop on-premises is the best approach, and has instead embarked on a journey to move their big data analysis to Google Cloud Platform, with the migration expected to be complete in early 2019.
Now, this is a really big deal from a business turnaround perspective. With the ability to run managed, massive, and scalable Hadoop jobs with services like Cloud Dataproc, King won’t have to spend time working on their own on-premises Hadoop clusters and instead let Google Cloud do the heavy lifting for them. So basically, we can expect their games to get even more addicting in the near future!
