Mike: Hi, Gurus,
In Azure, there's several different ways
that we can migrate file and blob data.
Azure Migrate Databox
is a secure offline data transfer solution
for moving large volumes of data to Azure.
It comes in different device options such as disk,
heavy and edge, catering to the various data sizes
that you may have all the way up to 80 terabytes.
Databox is ideal for scenarios
where network bandwidth is limited
or when dealing with large initial volumes
of data involved in the data migration.
The Azure storage migration service simplifies the migration
of on-premises file servers to Azure
because it supports various migration scenarios,
including lift and shift and phased migrations.
It helps to assess, migrate,
and cut over file servers to Azure,
which allows for minimizing downtime
and ensuring a smooth transition to the cloud.
The Azure import/export service is great
for one-time migrations
or scenarios where you have limited bandwidth,
and so it allows you to securely transfer large amounts
of data to Azure using physical disks.
You can ship your data on encrypted disks
to an Azure data center where it will be uploaded
to your storage account,
and it's crucial to follow best practices
and consider factors like disk encryption
and shipping logistics when using this service.
But in the case of extremely large data sets
that you have already on disks, this can be very helpful.
The AzCopy utility is a powerful command line utility
for copying data to and from Azure storage.
It supports various data transfer scenarios
including blob file table and queue storage,
and it offers high performance data transfer capabilities,
resumable transfers and synchronization features.
So it's an extremely versatile tool
for automating data movement and integrating with scripts
or pipelines.
AzCopy utility is one of those things
that you would often see in automation type functions.
Let's compare the different data migration solutions
we've discussed in this lesson.
In this comparison table,
we'll see each solution has its own strengths and use cases.
Azure Migrate Databox allows for up to 80 terabytes
to be stored from a device that is sent to you.
It's great for large one-time data migrations.
The transfer method is offline
because hardware is sent to you.
And because of the nature of that,
there's obviously no ongoing sync.
Azure Azure file sync,
which has been discussed in previous lessons,
the data volume varies.
It's great as a hybrid file sharing
and synchronization service,
and the transfer method is online
because it's using a network,
so you have, again, your Azure files
up in an Azure storage account syncing
with an on-premises file server,
and so there is an ongoing sync.
The storage migration service also varies
because it's more what you are trying to transfer up
and so it's migrating on-premises file servers to Azure,
and while it is online like Azure file sync,
there isn't an ongoing sync,
so it's not this perpetual type of connection.
The import/export service, like Azure Migrate Data Box,
is again, good for large one-time data migrations.
It's offline, though you're sending your own disks
to Microsoft, so you're sending your hardware there.
And again, the nature of that no ongoing sync.
And finally, AzCopy data volume obviously varies,
and it's for copying data to and from Azure storage,
specifically Azure storage accounts.
It is an online method and there is no ongoing sync,
but something we don't include in this chart
and to remember is that it is great
for large data transfers and synchronizations
and is also great to be implemented inside
of automation type functions like scripting.
Choosing the right data migration solution
depends on your specific requirements.
If you have large one-time data migrations,
consider Azure Migrate Databox or the import/export service
or AzCopy, or storage migration service
for online transfers.
If ongoing synchronization is a priority,
Azure file sync is ideal for hybrid file sharing.
While storage migration service is suitable
for migrating on-premises file servers up to Azure
as a permanent solution.
And if you're copying data to
and from Azure storage, AzCopy is usually your way to go.
Again, especially
when you're using automated functionalities.
When making your decision take into account
factors such as data volume, network bandwidth,
whether you are going to need an online
or offline type of migration, any security requirements,
and your overall migration objectives.
By selecting the appropriate migration solution,
you can ensure a smooth
and efficient transition for your file
and blob data to Azure.
