GCS BUCKETS, PLACEMENT, DISASTER RECOVERY

 

You can create different bucket which are containers that you use to house different files or objects in GCS. Buckets are similar to folders in a file system which can hold objects, like images, videos files etc. For example, in a financial environment, you'll have various buckets for savings, store ID's, payment. this will help you manage and segregate access within the buckets. You can set-up buckets in production and keeping it isolated from developers for best practice. 

Bucket names are unique. Google cloud storage name space is global. For example, apple-tech which already existed cannot be used. 

             BUCKET PLACEMENTS 

REGIONAL BUCKET:  Google cloud ensures that your buckets are spread across three AZ's. You can create a bucket that is placed in New York, North Virginia, MaryLand ( region). Storing data in a region closer to your users or applications can improve access performance and latency, government regulations and compliance, cost, durability. 

 DISASTER RECOVERY:

Disaster recovery could be from two angles in GCS. A disaster could come from customer side or google side. For example, from a customer side may be, someone goes and delete the bucket completely, probably because they had no knowledge what the bucket is used for and they felt its accumulating cost. In which they had data within the bucket that are critical. This will be disaster from the customer side. 

Disaster from google will be an inactive AZ . 

To advert this disaster from happening depends from the customer service agreement. A structure can be set-up to replicate data from one bucket to another. Google cloud provides a MULTI-REGION buckets. What google cloud does is that, it spread your bucket across at least three different regions, this means that when you store an object in New York, automatically google cloud will replicate it to MaryLand (REGION B)and North Virginia( REGION C). For example, If region C ( North Virginia) affected by fire, your object will be assessable. 

In the case where someone delete the actual bucket your DATA WILL BE LOST. Its one bucket that SPANS ACROSS MULTIPLE  REGIONS. Google cloud does not create the bucket. you might want to start looking for an option that you can make use of CREATING BUCKETS IN ANOTHER REGION. 

DUAL REGION BUCKETS

Your buckets is spread across two regions and everyday your data is stored in two region within a bucket. 

DATA TRANSFER SERVICE

You can use service to sync source. Data transfer service is a software  service that enables users to move extensive amounts of data from their data center to a cloud storage bucket. This is a separate copy of this same data in another region. This helps you to automate and schedule data transfers between different cloud storage. 

TURBO REPLICATION 

It only work with dual region .  Turbo replication provides faster redundancy across regions for data in your dual-region buckets. It  reduces the risk of data loss exposure. This does not work with multi and single region. 

How it work?

When it comes to turbo replication you do not establish a source bucket. You enable turbo replication to speed up replication data between GCS location.
