Aim:
To study and Implement Storage as a Service using its Own Cloud/ AWS S3, Glaciers/and Azure
Storage.
Theory:
Storage as a service (STaaS)
Storage as a service (STaaS) is a cloud business model in which a company leases or rents its
storage infrastructure to another company or individuals to store data.
Small companies and individuals often find this to be a convenient methodology for managing
backups, and providing cost savings in personnel, hardware and physical space.
As an alternative to storing magnetic tapes offsite in a vault, IT administrators are meeting their
storage and backup needs by service level agreements (SLAs) with an SaaS provider, usually on
a cost-per-gigabyte-stored and cost-per-data-transferred basis. The client transfers the data meant
for storage to the service provider on a set schedule over the SaaS provider’s wide area network
or over the Internet.

Advantages of STaaS
1. Storage costs
Personnel, hardware and physical storage space expenses are reduced.
2. Disaster recovery
Having multiple copies of data stored in different locations can better enable disaster
recovery measures.
3. Scalability
With most public cloud services, users only pay for the resources that they use.
4. Syncing
Files can be automatically synced across multiple devices.
5. Security
Security can be both an advantage and a disadvantage, as security methods may change
per vendor. Data tends to be encrypted during transmission and while at rest.
Disadvantages of STaaS
1. Security
Users may end up transferring business-sensitive or mission-critical data to the cloud,
which makes it important to choose a service provider that's reliable.
2. Potential storage costs
If bandwidth limitations are exceeded, these could be expensive.
3. Potential downtimes
Vendors may go through periods of downtime where the service is not available, which
can be trouble for mission-critical data.
4. Limited customization
Since the cloud infrastructure is owned and managed by the service provider, it is less
customizable.
5. Potential for vendor lock-in
It may be difficult to migrate from one service to another.

Amazon S3
Amazon S3 (Simple Storage Service) provides object storage, which is built for storing and
recovering any amount of information or data from anywhere over the internet. It provides this
storage through a web services interface. While designed for developers for easier web-scale
computing, it provides 99.999999999 percent durability and 99.99 percent availability of objects.
It can also store computer files up to 5 terabytes in size.
AWS S3 Benefits
● Durability: S3 provides 99.999999999 percent durability.
● Low cost: S3 lets you store data in a range of “storage classes.” These classes are based
on the frequency and immediacy you require in accessing files.
● Scalability: S3 charges you only for what resources you actually use, and there are no
hidden fees or overage charges. You can scale your storage resources to easily meet your
organization’s ever-changing demands.
● Availability: S3 offers 99.99 percent availability of objects
● Security: S3 offers an impressive range of access management tools and encryption
features that provide top-notch security.
● Flexibility: S3 is ideal for a wide range of uses like data storage, data backup, software
delivery, data archiving, disaster recovery, website hosting, mobile applications, IoT
devices, and much more.
● Simple data transfer: You don’t have to be an IT genius to execute data transfers on S3.
The service revolves around simplicity and ease of use.

Step 9: After uploading the same png file one by one, clicking on ‘Show versions’, we can
see that the Version ID is different for both
Step 10: Copying ARN for 'achufirst'
Step 11: Going to Permissions -> Edit Bucket Policy -> Policy Generator
Do as shown
