AWS S3 provides cloud storage and object storage services. It allows users to store and retrieve large amounts of data over the internet at a low cost. Some key benefits include durability, scalability, availability, and security. S3 stores data as objects within buckets and provides features like lifecycle management, bucket policies, encryption, versioning, and cross-region replication.

3. Cloud Storage
Cloud Storage Provides a Web Service where
- Your data can be stored
- Your data can be accessed easily
- Your data can be Backup up by the Users over the Internet easily
- Only Pay for what you use
- Best Part is you pay on Monthly Basis

4. Cloud Storage
This Cloud Storage Data is
- Reliable - data not going to be lost
- Scalable - stores 100/1000’s of data
- Secure - aws provides version control/security/permissions etc
than traditional On-Premises

5. Types of Cloud Storage
• AWS S3
• EBS - Elastic Block Storage (ssd HDD gets attached to your system)
• EFS – Elastic File System (Sharable file system)
• Glacier – Archiving Solution in Cloud
• Storage Gateways – Data to be stored from OP to Cloud and vice versa
• Snowball – Data Import and Export System
-- Actually an Hardware that is provided OP

6. Before AWS S3
• Challenge :
- Finding / Storing / Maintaining/Managing Data on Premises
ex :
- Running Applications
- Delivering Contents to Customers
- Hosting high Traffic Websites
- Backing up Emails
- Storing Req. high / Lot of Storages

7. Before AWS S3
• Maintaining Own Repository is Expensive and Time Consuming
What are the Factors :
1. Purchase Hardware and Software Required
2. Hiring a Team of Experts for Maintenance
3. Lack of Scalability based on your Requirements
4. Data Security Concerns / Very Expensive
Solve using – AWS Storage (S3)

8. AWS S3
• Simple Storage Service
• Provides an Object Storage Service
• Store Objects in Drive
• Cannot Install anything in Drive
• Can be accessed directly from Internet

9. AWS S3
• So
Amazon S3 provides Object Storage which is built for
- Storing Data over internet
- Recovering any amount of Data/ Information from Internet(S3)
- From Anywhere over the Internet

10. AWS S3
• Provides Storage through Web Services Interface
• Basically designed for developers
• Provides almost 99.9999999% of Durability and 99.9% of availability
• Can Store Upto 5 TB of file size

11. Benefits
• Durablity
• Low Cost
• Scalability
• Availibility
• Security
- Bucket Policy
- Encryption
- MFA Authentication etc
• Flexibility
• Simple Data Transfer

12. Basic Building Blocks of S3
Objects and Buckets in Amazon S3
- Object is the Actual Data
- Bucket is the Folder (stores data)
- demo

13. • When Files are uploaded to the bucket,
user should specify type of S3 storage class to be use for those objects
 Users can define
- Bucket Policy – accessing Policies
- Lifecycle Policies
- Versioning control etc

14. Storage Classess in S3
• Amazon S3 Standard for frequent access
• Amazon S3 Standard for infrequent Access
• Amazon Glacier
• One Zone – IA Storage Class (region Specific)
• Amazon S3 Standard Reduced Redundancy Storage

15. Features of S3
• Life Cycle Management
- Helps to migrate our data from One Storage Class to Low Cost
Storage Class
- Expiration Options Available
• Bucket Policy
- Is an IAM policy where you can allow or deny permissions to
AWS Users
- You can also define security Rules that apply to more than one
file within a bucket

16. Features of S3
• Data Protection
• Data encryption
• Data Versioning
• Cross Region Replication
• Data Acceleration using CloudFront
