Instructor: So now let's talk about AWS Data Sync.
It is used to move a large amount
of data from your on-premises system into AWS.
And it can synchronize to various destinations such
as Amazon S3, regarding any storage classes
including Glacier or Amazon EFS or Amazon FSX
and that includes Windows, Lustre
and the list will evolve over time,
but it will not update this slide.
Then you move also data, for example
from your NAS or file system via different protocols,
such as the NFS or the SMB protocol.
I will show you in the next lectures in the next slides
and then the replication test is very important.
They can be scheduled either hourly, daily, or weekly,
but they are not continuous.
Okay, they are scheduled.
Now to leverage data sync system
you need to install a data sync agent
on your systems or on your EFS file system if you need to.
And then in case it was using too much bandwidth
you could set up a bandwidth limits.
So let's go into the first use case where we replicate data
from our servers into AWS using the NFS or SMB protocol
and the target is S3 EFS or FSX.
So on premises we'll have our NFS or SMB server
and on AWS we'll have the AWS data sync service running.
So as mentioned, we need to install the data sync agents
on premises that will establish a connection using the NFS
or SMB protocol directly onto our server.
Then there will be a secure, encrypted
TLS connection between the agent
and the service on AWS and with a schedule.
Okay? So not continuously, but with a schedule.
It will replicate data either into Amazon S3
and the different storage classes
or the AWC FS or Amazon FSX.
And so remember in here, the key is that V.
So this really shows you the power to synchronize the data
between these on-premises system and AWS
and this is why it's called data sync.
But remember this is not continuous
this is something that runs every hour or every day
and it leverages a data sync agents.
Another use case for data sync is to do EFS to EFS.
So we want to synchronize, for example,
an EFS file system across two regions.
So we're going to have our first EFS file system
in the first region and then a destination region.
And so in this case, we're going to create an
EC2 instance that has the data sync agent installed
on it and connect to our Amazon EFS drive on their source.
And then the data sync service endpoint
on the other destination will synchronize the data
into the other EFS file system.
And so you, again data sync
is a really good use case for that.
So that's it.
If you remember this, then you're good to go
for the exam and I will see you in the next lecture.
