  AWS Object Storage 2 ▪Cloud object storage makes it possible to store practically limitless amounts of data in its native format ▪ As businesses grow, you're managing rapidly expanding but isolated pools of data from many sources that are used by any number of applications and business processes. ▪ Today, many companies struggle with a fragmented storage portfolio that adds complexity and slows down innovation for business applications. ▪ Object storage helps you break down these silos by providing massively scalable, cost-effective storage to store any type of data in its native format. ▪ With AWS object storage solutions like Amazon Simple Storage Service (Amazon S3) and Amazon Glacier, you manage your storage in one place with an easy-to-use application interface. ▪ You can use policies to optimize storage costs, tiering between different storage classes automatically. AWS makes storage easier to use to perform analysis, gain insights, and make better decisions faster.

  AWS S3 3 ▪ AmazonSimple Storage Service (Amazon S3) is storage for the Internet.You can use Amazon S3 to store and retrieve any amount of data at any time, from anywhere on the web. ▪ S3 = Simple Storage Service ▪ A Service Oriented Architecture which provides online storage using web services. ▪ Allows read, write, and delete permissions on objects . Uses REST and SOAP protocols for messaging, so you can use various development toolkits with S3. ▪ This guide introduces you to Amazon S3 and how to use the AWS Management Console to complete the tasks shown in the following figure.

  Create an S3bucket 4 To create an S3 bucket 1. Sign in to the AWS Management Console and open the Amazon S3 console athttps://console.aws.amazon.com/s3/. 2. Choose Create bucket.
• 5.
  Create an S3bucket 5 3. In the Bucket name field, type a unique DNS-compliant name for your new bucket. (The example screen shot uses the bucket name admin-created.You cannot use this name because S3 bucket names must be unique.) Create your own bucket name using the follow naming guidelines: ▪ The name must be unique across all existing bucket names in Amazon S3. ▪ After you create the bucket you cannot change the name, so choose wisely. ▪ Choose a bucket name that reflects the objects in the bucket because the bucket name is visible in the URL that points to the objects that you're going to put in your bucket.
• 6.
  Create an S3bucket 6 4. For Region, choose USWest (Oregon) as the region where you want the bucket to reside. 5. Choose Create. 6. Else you could configure for Versioning , access Log, Encryption, permissions etc.

  Version Control 7 ▪ Versioningis a means of keeping multiple variants of an object in the same bucket. ▪ You can use versioning to preserve, retrieve, and restore every version of every object stored in your Amazon S3 bucket. ▪ With versioning, you can easily recover from both unintended user actions and application failures. ▪ Versioning-enabled buckets enable you to recover objects from accidental deletion or overwrite. For example: ▪ If you delete an object, instead of removing it permanently, Amazon S3 inserts a delete marker, which becomes the current object version.You can always restore the previous version. ▪ If you overwrite an object, it results in a new object version in the bucket.You can always restore the previous version.

  Version Control 8 Key =a.txt ID: 1 Key = a.txt ID: 2 Key = a.txt ID: 3 • In one bucket, for example, you can have three objects with the same key, but different version IDs, such as a.txt (version 1) , a.txt (version 2) and a.txt (version 3) . • Buckets can be in one of three states: unversioned (the default), versioning-enabled, or versioning-suspended. • The versioning state applies to all (never some) of the objects in that bucket.The first time you enable a bucket for versioning, objects in it are thereafter always versioned and given a unique version ID. Important Once you version-enable a bucket, it can never return to an unversioned state.You can, however, suspend versioning on that bucket.

  Cross Region Replication(CRR) 9 ▪Cross-region replication is a bucket-level configuration that enables automatic, asynchronous copying of objects across buckets in different AWS Regions. We refer to these buckets as source bucket and destination bucket.These buckets can be owned by different AWS accounts. ▪ To activate this feature, you add a replication configuration to your source bucket to direct Amazon S3 to replicate objects according to the configuration. In the replication configuration, you provide information such as the following: – destination bucket – objects you want to replicate – storage class to use for object replicas in the destination bucket (storage class of source bucket)

  Cross Region Replication(CRR) Use-CaseScenarios ▪ Compliance requirements – Although, by default, Amazon S3 stores your data across multiple geographically distant Availability Zones, compliance requirements might dictate that you store data at even further distances. Cross-region replication allows you to replicate data between distant AWS Regions to satisfy these compliance requirements. ▪ Minimize latency –Your customers are in two geographic locations.To minimize latency in accessing objects, you can maintain object copies in AWS Regions that are geographically closer to your users. ▪ Operational reasons –You have compute clusters in two different AWS Regions that analyze the same set of objects.You might choose to maintain object copies in those Regions. 10

  Life Cycle Management 11 ▪To manage your objects so that they are stored cost effectively throughout their lifecycle, configure their lifecycle. A lifecycle configuration is a set of rules that define actions that Amazon S3 applies to a group of objects.There are two types of actions: ▪ Transition actions - Define when objects transition to another storage class. For example, you might choose to transition objects to the STANDARD_IA storage class 30 days after you created them, or archive objects to the GLACIER storage class one year after creating them. ▪ There are costs associated with the lifecycle transition requests. For pricing information, see Amazon S3 Pricing. ▪ Expiration actions - Define when objects expire. Amazon S3 deletes expired objects on your behalf. ▪ The lifecycle expiration costs depend on when you choose to expire objects.

  Amazon Glacier 13 What IsAmazon Glacier? • Amazon Glacier is a storage service optimized for infrequently used data, or "cold data." • Amazon Glacier is an extremely low-cost storage service that provides durable storage with security features for data archiving and backup. • With Amazon Glacier, customers can store their data cost effectively for months, years, or even decades. • Amazon Glacier enables customers to offload the administrative burdens of operating and scaling storage to AWS, so they don't have to worry about capacity planning, hardware provisioning, data replication, hardware failure detection and recovery, or time-consuming hardware migrations.

  Amazon Glacier 14 What IsAmazon Glacier? • Amazon Simple Storage Service (Amazon S3) supports lifecycle configuration on an S3 bucket, which enables you to transition objects to the Amazon S3 GLACIER storage class for archival. • When you transition Amazon S3 objects to the GLACIER storage class,Amazon S3 internally usesAmazon Glacier for durable storage at lower cost. • Although the objects are stored in Amazon Glacier, they remain Amazon S3 objects that you manage in Amazon S3, and you cannot access them directly through Amazon Glacier.
