Hello again. And welcome to cyber is cloud architecture foundations. This is module four storage foundations. The idea about this module is that before you move your critical data stores repositories and backups to a cloud platform, the assumption is is that you have your arms around storage this module being be very basic to you advanced students. If so,
00:29
do like the engineers that I work with do and play back these recordings at 1.5 or two times speed.
00:35
It won't make you pass your certification any faster, and you probably aren't retaining any better. But it sure makes you feel smarter. Anyway. Storage in general is really ah lot about speed.
00:46
How fast do I write my information and how fast do I read the information? And what of my organizations are pose an art Eos recovery point objectives and recovery time objectives.
00:56
And once I have my arms around these things, I can talk intelligently about my storage, my cloud platform, my storage in my cloud and what level of performance I demand from those solutions. So if you're ready, let's start writing a disk or writing the flash we're even. Let's start writing to the cloud.
01:14
So in this introduction of storage, we're gonna take a few steps back and talk about the history of storage and storage, technology advancements and where storage is going. We're talking to customers in the Enterprise today about petabytes of storage. That's 1000 and 24 terabytes, or one million gigabytes
01:30
or another way to think of it has tended the 15 bites or one quadrillion bites or
01:34
1,000,001,000 bytes of information.
01:38
That's just a few bits for a soul that you are.
01:42
So what we're going to cover in this module? Well, we're gonna learn about dis drives and dis media, and we're gonna spend some time about data, redundancy and the concepts of writing data across multiple disks. So if you lose some data, you can recover through technologies like raid were done, an array of independent discs, and then we're gonna spend some time around storage architecture. This is a big deal
02:02
because we need to have an understanding of what direct attached storage is, or daz network attached, Storage is or nasty,
02:08
and storage area networks were sands are because it's this architecture that we're gonna ask our cloud computers towards platform. If you excuse the pun mirror for us and even more pun replicate for us in the cloud instead of being on premise.
02:23
And if we're gonna talk about file level or folder level backups, we need to understand file structures and file systems. And one of the most important cloud storage capabilities that we can take advantage of is backing up our dated to the cloud to help or organization with its business continuity continued operations or coop and disaster recovery capabilities, or D. R
02:43
In case of an incident, be it man made or by nature
02:46
lost 80 equals lost business revenue. So determining and delivering on our organization's recovering point objectives and recovery time objectives. RP Ozark EOS is critical if we're going to minimize our losses when a risk to our business enterprise actually occurs. So fear not,
03:01
because we will leave no bit behind because we're going to, well, store it.
03:07
For now, let's rev up the spinning platters of aluminum alloy and start writing with our magnetic ones and are de magnetized heroes. Except for those of you who are watching this video on a flash drive. Then just, uh, I guess tunnel electrons with the flash of electronics charge into your storage cells.
03:23
So if you remember from an earlier lecture, the first form of data storage was punch cards. The first form of punch cards were holds in cloth way back in the 17 hundreds,
03:31
then with the modern era and the Industrial Revolution from 1900 to about 1970 IBM punch cards with a primary way corporations and governments stored in access to information with the invention of computers there came to need for larger data storage methods.
03:46
And a device created by R C A, known as the Selectron tube, was developed in 1946. And then a few years later, magnetic tape was released is an improved way of storing data. This then led later to compact cassettes and VHS. In 1956 IBM once again created a new technology known as the hard Drive.
04:03
These first hard drives were 25 inch disks,
04:06
which could store five million characters or five megabytes of data. And then, in 1971 once again, more innovation from IBM. IBM created the first memory disk, which allowed users to transfer data from one computer to another. These portable disc were called floppy disks because they're more flexible and cheaper than the big, expensive hard disks,
04:27
even though they couldn't stores much data.
04:29
The invention of the floppy disk was followed by the invention of the CD in 1979 and the DVD in 1995.
04:35
Computer storage then led to the invention of USB drives and memory cards, which allowed users to easily save large files and transfer them from one place to another. And tremendous advancements have been made in spending hard drives and the new flash drives all solid state electronics storage media drives.
04:53
Storage is now about lightning fast I ops and putting output per second performance
04:57
and massive storage retention. Or once we measured in megabytes and gigabytes now terabytes and even petabytes.
05:05
So I always love me Some graphs and charts. And thanks to a study by the Enterprise Storage Forum in August of 2018 these graphs indicate a most comprehensive portrait of today's data storage landscape. Storage growth is skyrocketing, and you hear terms like big data, which is the huge amount of data created and analyzed about data.
05:25
So for your video junkies out there, 100 hours of YouTube video are uploaded to YouTube every minute.
05:30
If we needed to store YouTube videos for archival purposes, say, for example, 15 years, we would require over 100,000 hard drives on the server. To spend. All these disks would need to process 1 60 million gigabytes of data, which is a one with 19 zeros and bites or exabytes.
05:48
And you can see from the grafts that hard disk drives
05:51
are large portion of the enterprise budget. And the only budget item bigger than displacing the enterprise is where the disk space lives in the cloud. So case you are wondering a big part of the clouds story and the value of cloud platforms like Microsoft, Azure AWS and Google Cloud Platform G. C P is the enterprise.
06:10
I just can't get enough of cloud storage
06:13
so you can see an even more graphs and charts that the current storage technologies is tthe e enterprise are flash solid state drives, hard drive's spinning disks and cloud storage. A really cool, newer technology that we talk on later is up and coming in the enterprise, and that is what the industry calls hyper converged infrastructure
06:29
and the chart on the right shows that our primary storage, that storage,
06:32
which we know as his hot stories, which we write too frequently and read frequently in the 1st 30 days and then that warm storage, which is less frequent. But over the 1st 12 months that warm and hot storage, which we call primary storage. Well, we're putting that right now on hard disk drives and in the cloud,
06:53
but that's gonna change.
06:54
What we're going to see over time is that flash drives and hyper convert storage infrastructure because they're gaining stream, are gonna take over and it's gonna be cloud first. And then our premise disc will be flash and hyper converged technologies that will replace the legacy spinning hard disk drives over time.
07:13
Now, these charts and graphs, we're really getting out of hand, and I would agree with you. But the last two points that I have to share can only be done with the power of the amazing bar graph,
07:23
and that's that The enterprise is challenged with the high cost of maintaining their storage infrastructure, and it's not delivering organizational business outcomes due to poor performance. So what the enterprise hopes to gain out of a new storage technology is performance, reduced operating expenses and cost savings while also increasing security
07:41
scale, ability and simplified management.
07:44
And guess what? All of these business intendant locals of new storage technologies are met by today's cloud storage platforms. And that's why cloud storage is so compelling to the enterprise and why this module is so important to us. Cloudy I t. Aficionados,
07:59
look out! We got the blue screen of death. We have a memory exception air, and it's time to run our memory diagnostic tool. So here goes.
08:07
Why did IBM call their invention a floppy disk?
08:11
Megabytes, gigabytes, terabytes? And
08:16
today what to technology Store? The enterprise is primary storage,
08:20
and over time, what will the current primary storage technology in their price be replaced with So hit? Pause. Write your answers to read only memory in case you lose power. And then while you're still running and random access memory RAM head play and we will review our answers together.
08:35
So why did IBM called our portable storage media a floppy disk because it was flexible compared to the big and heavy metal hard drives, megabytes, gigabytes, terabytes and petabytes of PETA bite is 1000 and 24 terabytes, or a 1,000,000 gigabytes.
08:52
What are the two primary storage technologies in an enterprise today? Hard disk drives made a spinning disks and cloud storage. And what well spinning distant clouds Stores be replaced with the store organizations hot and warm, primary storage, cloud storage and, for on premise, legacy spending. This will be replaced with flash solid state drives
09:11
and hyper converged infrastructure.
09:15
So in today's lecture, we discussed a little history of data storage, the current trends and challenges and storage for the enterprise, and how the future of storage will be the cloud first and then for own premise, solid state flash drives and hyper converts infrastructure. HC I. So the next time we meet, we'll start opening the lid of our drives and learning about distorts operations
09:33
and disk level redundancy through technologies like Raid,
09:37
where we write our data striping across multiple disc for resiliency and identity.
09:43
So, until next time, on behalf of all of us, the cyber Security and I t Learning Team, we want to wish you and all of the users on your network
09:54
very happy packets
09:54
and have a good day
