Everyone, and welcome back to the Knowledge Guru video series, and in today's lecture, we will be
speaking primarily about this Turetsky trip last week.
Its gateway is a nice hybrid based solution, which is normally used in on, but it might be.
So let's go ahead and understand more about it.
So either asterisked is a hybrid storage service that allows on premise applications to easily use cloud
storage.
Now, let me give you one of the examples.
Let's assume a compromise application wants to store certain files in Ebb's or store certain files in
S3.
Then what you need to do is you have to put the entire logic related to AWG integration of SDK to the
application so applications should be able to connect to the S3 bucket and then store later in that
extra bucket.
So the entire logic needs to be written.
Then comes the issue of putting that Idalis access key, a secret key rotation policy and so on.
So that is one.
Now, secondly is to use to this house to get to is a very nice solution.
So all credit goes to the enablers that bring up for the images that I'm using.
I thought I'll not reuse on recreate and that image, which is already created so less and less than
on how to get Gribbles.
Where you have an application server now, this is customer on Premi, so you can consider this are
the leaders in all the local on which client might have.
So on the left hand side, you have a customer on premise and on the right hand side you have the storage
solutions enablers like S3 Glacier or Ebb's.
No.
The thing which is connecting both of them is the story to get to it, so you have a stewardess Gateway
Appliance on the customer side and you have a stewardess get back in under a W.S. So what basically
happens is the stewardess Gateway Appliance will create a desk and that desk can be used by the application
server to store their data.
Now before it gets confusing.
Let me actually show you and how exactly that might what?
I haven't this Coya amateurs, I remember we had discussed about this when we were speaking about Ebb's
portability and then network attached to reselected.
So I have a disco Eyskens disc now.
This disc contains a file.
Is that there not be?
No.
I can easily create any number of Fallujah, let's say Capi Labs or I find them under 18.
No.
What happens in stories Gateway is today's Gateway Appliance, so this specific appliance will create
a disk similar to this, like I drive.
And whatever application that you create, you can store all the application related data or all the
backup files within this specific bright.
Now, whatever they used to it in this drive, this specific drive, the storage appliance will applaud
that data or indented because stories of plants can be connected to one of the storage volumes, which
is a glaciated eBay's snapshot.
So whatever data they're to upload in that specific drive, the storage gateway will upload that data
in a compressed manner to either Idalis, S3, Glaisher, EBAs, depending upon the configuration that
you have done on this story.
A Gateway Appliance.
Now, this is the reason why there is a direct connect, which also comes in case you have a lot of
detail, terabytes of data, but just put it in your disk right then.
Internet is not a viable option.
That is where their direct connect really comes into picture.
So.
Let's look into the stories Gateway configuration, I hope you understood the basic or what is too risky.
We basically can do know one of the beauty about stories is that it is actually it works on the.
Local on my side.
So I don't really have to worry or have to worry is that I have to store data in this specific dry and
storage.
It will take care of the entire backup related functionality away.
So let's go back to that presentation.
And look into the various configuration related parameters.
Now, one important thing to remember is that the storage do appliance uses standard studies protocol
like an office or ICAC to monitor the.
And on the other end of the story, which is the right hand side, the storage gateway connects to the
storage services like a street Lucia, or that data can be stored in form of incremental ebb's snapshot.
So if at this there are three type of storage gateway configuration that one can have, one is the gateway
to the value.
Second is the gateway cache to value.
And third is that they do what's called a BlackBerry, also called in the middle.
Now you need to understand each and every one of these as a form of a use case.
Which will be presented to you in the exam.
So let's start with each one of them.
Now, Gateway stonewalling what happens in Gateways to value is that whatever data that is stored in
that disk drive will be stored locally.
However, every time in Dodwell there will be an asynchronous backup of data to eatables.
Like every one week, the gateway volume will take the backup of the entire drive and it will store
that data in the cloud storage.
So this is what is the gateway to the volume.
Now, this is why you have an asynchronous backing of both data.
And this time interval can be.
Just according to what we are required now, if you look into the database to get away with it, you
have a volume storage and you have the upload buffer.
So volume storage is present within the UN, but it might it's and that means all the data will be stored
in this volume storage and whatever data that needs to be uploaded will be part of the upload beaufoy.
And this is connected to this to this gateway service on the other side.
And then you can store it in a specific cloud storage opportunities available to us.
No gateway stored volumes are very beneficial when a customer wants to access large amounts of data
at a very fast rate.
So this is one of the use case of gateway stonewalling.
Now, the second configuration type is the gateway guys to volume.
Now, what happens in Gateway guys to value is data is stored primarily on S3 Vikash I've recently read
or hidden data stored locally in the UN, but in my server.
So whatever data that you stored or whatever data that you put in the storage gateway, that data will
be uploaded to the S3.
So nothing will be stored.
On premise exit the gash of recently read recently.
Radar data, and this is the reason why if you see where there is no volume gateway, let me open the
gate, restore volume.
There was a volume storage area and upload buffer.
However, for Gateway cached volume, there is no volume storage.
So data is actually not stored locally.
It is directly backed up to the S3 stories.
And this is one thing which is very important to remember.
So in certain cases like example present to certain use cases where application or a client wants to
store a large amount of data, but he will be accessing only certain portions of data.
In a day to day basis, so what type of configuration of storage gateway should you use?
Should you use Gateways Stuart or Gateway Gas and then your answers should be in gateway gas.
So I hope you understood the difference between gateways to the gateway gas.
Now there is one more configuration parameter called Gateway Watergate Library.
Now, this is one thing which is quite important to understand, because the majority of library is
something that most of you have not familiar with.
So let me show you why.
Some of the advantages of eBay storage so generally, albeit available, is very aware about the portable
hard disk.
We are available about the SSD, which are quite famous, and that traditional traditional hard disk
drives, which contains like this, however, the price of something which many of you might have not
seen.
So basically it back up is a very common practice.
All periodically copying data from primary storage device to a tape cartridge so data can be recovered
if there is any data collection failure on primary device.
So basically big solutions are used for storing backups and archives.
Now, one of the benefits of it being studied is that it remains very cost effective.
And this is the reason why the data centers are not a big organization.
This to the data in form of DBS within the organization.
So this is going to be storage and this is where the virtual dome really comes into the picture.
So what happens in Watergate is that what keeps us today as three frequently access data on premise?
So this is something like a cache to you.
However, the.
The debt that will be stored will be informal virtually no, remember, the term is virtual dates and
not physical tips.
So what is a virtual today?
So what you need is basically hard disk drive.
We need, however, the way in which you write the data and the way in which things work in water tables
are quite different from a traditional hard disk.
It tries to follow the configuration of a traditional beat based storage.
So it is three.
You have the data which is good in terms of what your DBS.
So.
When you talk about water, did you see you have a backup server and you have a tape gateway, now this
data is stored via a sticky piece and it can be stored as what your tapes in history or archives be
stored Amazon.
So this is something that we can store data and do now.
You don't really have to worry more about how it really works and the practicality aspect, because
this is something which is a far, far away the practical aspect as far away from what you are expected
in the exam session.
Now, only thing that you need to remember is what is a storage gateway, how exactly it really works
in the high level overview, along with the reconfiguration parameters like gateways to the volume Gateway
Castorena and what deployability that we're looking at.
So this is about Storage Gateway.
I hope you understood the basics about Storage Gateway and why it is used.
