This video defines the basics of cloud storage, including block, file, and object storage.
- [Instructor] Okay, let's talk about cloud storage. Anybody who's in IT understands that the growth of storage has been explosive. As you can see by this diagram, between 2011 and 2015, we had a wholehearted explosion in terms of storage that was needed within enterprises. Why is this? Social media, media files, video, multimedia kinds of information that are stored, large databases, big data, replication of data. You can basically name your poison.
So what happened is we hit explosive growth in data, and we had a IT budget shortfall that occurred at the same time. So you'll see IT budgets did increase, but the cost of storage did decrease. However, we're spending way too much on storage based on the value it's able to return back to the business. And we have an IT budget shortfall, or, in essence, it just doesn't make sense anymore for us to go out and buy huge amounts of hardware to store our information that exists within our data centers, within our businesses, within our enterprises.
However, it's a problem that we need to address. However, there needs to be a bigger, more strategic solution in how we're gonna store all this data and make it available to us to serve the needs of the business. Businesses will consume incremental IT budgets just to attempt to keep up with the costs of data growth. So most IT budgets, when you look at them, the line items don't go to people and innovative processes and building business systems to make our business run better, but they'll go to storage systems.
They'll go to spending money on disk packs from IBM and EMC and other companies out there that basically are doing a good job in providing on-premise storage. But we're exploding so much that the data center space and the cost of the people needed to maintain it, as well as the cost of the hardware, is just growing way out of proportion in terms of the value we're able to get from the storage. So what's occurred now is that we've leveraged cloud as a storage process both at the retail level, in other words, basically the consumer systems that you use everyday, such as SkyDrive, Box, iCloud, Dropbox, Google Drive, things like that, and it's becoming part of our lives.
However, moving to enterprise-based cloud storage with something that's able to solve the problems that we just discussed is we'll take large public cloud providers that are able to provide storage systems that will scale to the enterprise-level needs, in other words, scale to petabytes, multi-petabytes, and the ability to provide fast disk access between the enterprises and the cloud systems out there. So we have Google Cloud with their storage system, we have Amazon Web Services with their storage system, and we have Microsoft Azure with their storage system, that are out there and ready to use.
Let's learn more about these. So at the heart of the cloud storage is Amazon. They have four different storage offerings, and we're gonna review them in this course. They include Amazon S3, a durable object storage for all types of data. We'll understand more about object storage later in the course. Amazon Glacier, archival storage for infrequent access data. In other words, a very slow storage device, which is designed just to basically maintain backups and recoveries of existing files and data systems.
Amazon EBS, block storage for use with Amazon EC2. And Amazon EFS, Elastic File Storage, for use within Amazon EC2 as well. Let's explore these more.
