Here you are.
And welcome back.
Now in today's video will be discussing about the three cross region replication now in many of the
organizations that are compliances, that has a lot of requirements related to how the data must be
replicated across multiple distances.
So let's take an example where you have an organization and all of the organization is important.
Data is part of the S3 bucket in Mumbai region.
Now, in case as a worst case scenario, if this Mumbai region becomes unavailable due to some issue,
then all of the data as part of the organization will become inaccessible.
And this is the reason why compliances, they have a requirement that the data must be replicated across
greater distances.
So if you're storing your critical data in Mumbai region, also make sure that the data is replicated
in a different region, let's say Singapore, and this gives a better flexibility in case of a worst
case scenario of a region going down.
So this feature of replicating the data of a three -- across multiple region is achieved with the
help of cross region replication.
Now, before we go ahead and start with our practical, one important part to remember is that for the
S3 Cross Region replication feature to work, both the source as well as the destination buggy must
have the burgeoning feature enabled.
So with this being said, let's go ahead and try it on.
So currently I am in my Estragon, so let's go ahead and create a bucket list.
Escalator's might be Lapps hyphen Mumbai bucket and this will go ahead and create it within the Mumbai
region.
Let's create a bucket and in a similar way, let's also go ahead and create one more bucket.
Let's call it as my copyleft hyphen Singapore bucket and let's this time will go ahead and choose the
Singapore region.
Great.
So both of our buckets are created.
First, let's go to the Mumbai bucket here and within the management.
Let's go big.
Don't you have the option for application rules?
So if you go ahead and create a new replication rule here and yet immediately you get a warning stating
that the application request was going to be enabled for the sourcebook.
So this is fine.
You can go ahead and enable the warning from your gr8.
It states the bucket versioning has been enabled.
You can just give it a rule name, let's say Mumbai to Singapore.
So this is the source it.
And now you'll also have to specify the destination bucket, whether it is in this account or in the
destination account.
So I just use a bucket in this account.
Let's quickly do a browser history and we are interested in the Singapore market again for the Singapore
McGarity stating that their application requires versioning.
So let's go ahead and enable bourgeoning for Singapore market as well.
And once then the next important part is due to the IBM rule.
So I'll go ahead and create a new role and then let's go a bit down, will go ahead and will do a both.
So our application rule has been created.
The U.S. automatically, a new IBM rule also has been created and it basically gives you details associated
with it.
So now let's go back to our Mumbai Buckethead.
And just to test if everything is working, let's go ahead and upload an object in the Mumbai market.
I like the file, so I have a template to extend that is available.
We'll be uploading this specific file boffing.
So object is available in the Mumbai region to see if it is also available in the Singapore region.
Let's open up the Singapore market now.
At this stage, you see the object is not available primarily because it takes a little amount of time
for the application also to complete.
So let's quickly wait for a moment here.
And now.
You see, our object is also available within this Singapore region.
Great.
So I hope at a high level or you you understood the importance of replication across multiple region
and how it can be achieved in a street with the help of cross region replication feature so that this
will conclude today's video.
