What is cloud storage?

Cloud storage is a model that is used to store data in digital format in separate pools build logically. These logical pools are called clouds. The physical storage of this data happens across several servers located at different geographical locations. These servers are managed and maintained by the cloud service provider. The prominent cloud Service provider in the market today are Amazon, Microsoft, Google, and so on.

1960: Cloud computing was invented by Joseph Licklider to connect people and data across different locations at any given time.

1983: CompuServe allowed its user to use its disk space to upload files for storage purposes.

1994: PersonalLink Service was launched by AT &T, an online platform for data storage for budding entrepreneurs.

2006: AWS S3, a cloud service by Amazon, was launched.

By using cloud services, companies were able to pay only for the services they are using. It also provides an environment where all their software could be quickly developed and deployed. Also, testing could be easily carried out in these environments. This also helped in reducing the consumption of energy, promoting Green business. As a business owner, now these entities need not have to worry about the maintenance of infrastructure. These aspects were looked after by the service provider. It also provided backup services in cases of natural disaster, securing the large data sets. Also, it provides a secure environment for the storage of data.

Types of AWS storage

There are different types of AWS storage services made available by Amazon.

What was the scenario before AWS S3?

Large companies have a lot of data belonging to the employees of their company. They also have several projects that they are working on, which generates a large amount of data. Also, a lot of data is created from hosting websites, the backing up of emails, etc. Now the problem arises in storing this data. It is an expensive affair to store these large data sets as it involves purchasing hardware devices. Also, they need to get the necessary software. They would need an expert team to manage and maintain this data, which is an overhead for the company in the long run. Also, the security of data is a major concern.

These issues are resolved by using the Amazon S3 system. So let us now understand What is Amazon S3? Or What is S3?

What is AWS S3?

AWS S3 is a cloud service offered by Amazon. S3 means Simple Storage Service. Amazon occupies 32% of the market share for cloud services. Currently, it is a primary service provider. A storage facility is made available through a web interface. It can be ideally used by developers to develop, deploy, and test their software applications in AWS environments. It guarantees 99.9999 % durability, scalability, and availability of objects.

Amazon S3 is a system used to stores files up to terabytes in size. This feature will ensure that we have our data available anywhere and anytime without any errors.

Benefits of using AWS S3

  • It can store an infinite size of data.
  • It is less expensive, and it only costs as per usage.
  • It will provide efficient service without affecting the customer experience.
  • The applications can easily be scaled and available on the AWS S3 cloud environment.
  • Data is safe and secure when stored in AWS S3.
  • It provides flexibility and effortless transfer of data.

Buckets and Objects in AWS

Objects are the essential component that is stored in the Amazon S3. It is made up of object data and metadata.

objects and meta data

Amazon S3 cannot see the object data. Meta-data is a combination of name and value pair that is used to describe the object.

Buckets are used to store these objects in S3. Within a bucket, an object is recognized by a key name and version id. Every object is identified by combining bucket no, key name, and version id.

For example, if an object photo/amazonlogo.jpg needs to be stored in an AWS S3 bucket awsbucket1 in the US(East) region, it will be addressed using the following URL.

https://awsbucket1.s3.us-east.amazonaws.com/photo/amazonlogo.jpg

aws bucket

Bucket Name: awsbucket1

Key Name: photo/amazonlogo.jpg

Steps to create an AWS S3 bucket
  1. AWS Management Console is used for the Amazon S3 login.
  2. Go to the AWS S3 console at https://console.aws.amazon.com/s3.
  3. Click on the tab Create bucket.

create bucket

  1. Enter the name of the Bucket. The name of the Bucket cannot be changed at a later time.

The following things need to be kept in mind while creating one.

  • The minimum length is three, while the maximum size of the bucket name is 63.
  • It should be unique across all AWS S3.
  • It should start with a lowercase letter or a number. It cannot contain an uppercase character.
  1. Under the Region field, enter the location of the AWS S3 server. An object created in a particular region remains the same until you transfer it to some desired region.
  2. Block Public Access is a setting in Bucket. This is used to provide public access to the Bucket for all the access points. By default, the buckets are not accessible by the public. But if needed, you can turn off any setting if you wish to host a public website.
  3. S3 object lock settings is an option available in Advanced Settings. It is used to lock the S3 objects for protections. Once it is enabled, it can’t be disabled during the lifecycle of the object.
  4. Click Create Bucket to finish the process.
  5. Once the Bucket is created, you may add files to this Bucket. Click the Upload button, and select the file you wish to upload.

steps to delete s3 buckets

Steps to delete an S3 bucket

  1. Log in to AWS Management Console.
  2. Go to the AWS S3 console at https://console.aws.amazon.com/s3.
  3. Select the bucket name you wish to delete.
  4. Click the Delete button at the top of the page.

delete bucket

  1. The next Delete page will confirm the bucket name by asking you to enter the same in the text box. Once you confirm, it will delete the bucket.

Once a bucket is deleted, all the objects within the bucket are also deleted. Once the bucket is deleted, the bucket name is now available for other AWS S3 users.

If you have configured a static website on Amazon 53 Router using the bucket, you need to clean the settings on Amazon53 Router for that bucket.

AWS S3 logs are used to track the permission for accessing the bucket. It contains the details about the request made that includes requester, name of the bucket, time of the request made, the response status received, and error code in case of any failure.

We can also create and manage buckets and objects in Amazon S3 using the S3 browser. S3 browser is the Windows client available for free. This makes storing and accessing any data on the web more accessible.

How do Amazon S3 works?

We have already seen in the example above that the user needs first to create an S3 bucket. Whenever the bucket is created, files or objects to be stored can easily be uploaded using the Upload option. Once the file is uploaded, we need to find which S3 storage class needs to be used for that bucket.

S3 object classes are configured at the level of an object. So any bucket can contain objects stored across different storage classes. S3 lifecycle policies can be used to move the objects among other storage classes without making any changes in the application.

Different AWS S3 storage class

  1. S3 standard(Amazon S3 standard): This is used for frequently accessed data. It provides low inactivity and higher throughput. It is used for dynamic websites, gaming apps, and analyzing Big Data. For example, when you want to access the attendance of employee data.
  2. S3 standard IA(Amazon S3 standard for infrequent access): This is used for the data which is not frequently accessed, but when accessed, it needs to be done at a rapid rate. It offers low fees for storage and retrieval, even for GB sizes of data. This is ideally used when we need to store data for a long time, backups, and stored data to recover from any disaster. It is a cost-effective storage class giving high performance. For example, when you want to access the performance record of employees.
  3. S3 Intelligent tiering(Amazon S3 Intelligent tiering): This storage class consists of 2 tiers. The first one is used for frequently accessed objects, while the latter is often used for not often used objects. If you haven’t accessed an object in the frequent access tier for 30 consecutive days, it will be moved to the infrequent access tier and vice-versa. There are no retrieval fees charged to the user. Amazon charges only small monthly and auto-tiering fees. If you do not know the access pattern for an object, you may store it in this storage class. For example, when you want to access the work record of employees.
  4. Amazon Glacier(S3 Glacier and S3 Glacier Deep): S3 Glacier is mainly used for archiving data. It offers a competitive rate for storing data than its fellow competitors. It is ideal for those users who need to store data for a long time but accessed regularly. It needs to be retrieved within a couple of minutes.

S3 Deep Glacier offers the lowest fees for storing data for a long time. This data can be accessed only once or twice in a given year. It is ideally used by Health and insurance sector who need to retain data for 5-10 years only for compliance. The data is stored at three different geographical locations to maintain the durability and quickly be restored within 12 hours.

For example, it is storing data for ex-employee.

5. S3 on Outposts: It is used to store data close to the on-premise location. This will help to reproduce the data quickly. It is also used to store non-critical data. It helps to provide better security of data.AWS Data Sync is used to transfer the data to AWS regions.

Features of AWS S3

  • Permission to host website: A customer can easily host their AWS S3 and map to their domain. This saves expenses as the customer only pays for what resources they have used. The customer also need not have servers with high configuration to provide services to their website.
  • Reliability: Amazon storage S3 assures 99.99% reliable uptime of servers. So customers can be assured that their data is reliable too.
  • Scalability: Any AWS S3 storage user can store any size of data n AWS S3 servers. Now the customer needs to pay only for the services used. There is no separate S3 storage cost.
  • Security: Any Amazon S3 customer can enter the console after proper authentication. Only after clearing this authentication step, the customer has the privilege to alter any data. It also provides the privilege to give necessary permissions to create, delete, and update the data stored as objects in a bucket.
  • Interfaces for web framework: REST and SOAP are the standard interfaces available for the AWS S3 web framework.
  • Tracking of torrents and seeding: Amazon S3 follows the torrent and seeds the file in the system.
  • Generating a temporary URL: A temporary URL is created for Amazon S3 storage users. This can be shared with other people giving them limited-time access. After this, the user can access the data using the URL.
  • Logging: Amazon S3 gives the facility to logging to perform activities on the bucket. Using this feature, you can audit the activities of the bucket.
  • Versioning: AWS S3 storage user can maintain older records of objects. This helps us in saving from any data loss that has happened unintentionally.
  • Integration: AWS S3 can be integrated with services like Amazon EBS, Amazon EC2, etc. AWS S3 storage is generally used to store files of the type images, documents, videos. It can also be accessed using HTTP get.

What is Amazon S3 used for?

  • Amazon S3 Simple Storage Service Gateway is used to store backups and share files of on-premise software applications through cloud storage.
  • AWS Snowfall family also provides offline transfer of data during migration where there are network constraints.
  • It also offers faster transfer of large bytes of data over a long distance.

Is Amazon S3 a database?

No. It is not a database. It is file storage. It is used to store files in the form of objects in a bucket. It is identified by key-value pair where the key is the file name while the value is the data’s content. It is mainly used to store unstructured data of huge size. The maximum size allowed for an object is 5TB.

How much does Amazon S3 cost?

AWS S3 pricing depends on the object’s size, the duration for which the object is stored, and the storage class used. The source for the below data is

Amazon S3 vs. EC2?

Amazon S3 is a simple storage service that is used to store data in the cloud. S3 can host static data that the website is using. It is not preferred to store data that is used to host dynamic websites. At the same time, Amazon EC2 is commonly used to host websites or software applications.

S3 buckets are used to store the data present in the EC2 instance. Also, it is possible to access the S3 bucket using an EC2 instance.
