What Is AWS? AWS Database and Its Types

In this AWS article, we will learn together what is AWS? AWS Database and Its Types. Before, cloud companies were required to deploy and manage databases on their in-house servers. This required monetary resources, time, and personnel for the efficient work of the infrastructure. It was an excessively tedious job, especially for small-scale companies. Cloud service provisioning changed everything by providing managed services in various domains required for infrastructure setup, including databases. In this blog, we will be discussing the following:

What is AWS?

AWS (Amazon Web Service) is a set of cloud services provided by Amazon, which also provides various databases as part of its service suite. These Databases allow users to build use-case-specific data models, including relational, graph, wide-column, etc. AWS fully manages these databases, freeing users from tasks such as server provisioning, patching, and backup, which are incredibly time-consuming. Check out the free aws course.

Must-read: Amazon Web Services (AWS): Benefits, Use Cases, Applications

Advantages of Amazon AWS Databases

  • Fully Managed: AWS Database services are fully managed services that relieve many of the setup, management, and monitoring responsibilities off of the business’s shoulders. 
  • Scalable: AWS provides a set of Databases that are highly scalable when compared to popular alternative databases. This is true for both the relational and non-relational databases provisioned by AWS.
  • Highly available: Given its global infrastructure setup and fault tolerance mechanism, AWS provides highly available and reliable services across the globe.
  • Security: Provides highly secure services due to the implementation of multi-level security systems like network isolation and end-to-end encryption.

Types of AWS Databases

As stated previously, AWS provides a variety of relational and non-relational databases as cloud services for users. Given below is a list of these database services.

  • Amazon Aurora
  • Amazon Redshift
  • Amazon RDS
  • Amazon Dynamo
  • Amazon ElastiCache
  • Amazon DocumentDB
  • Amazon Keyspaces
  • Amazon Neptune
  • Amazon Timestream
  • Amazon Quantum Ledger Database (QLDB)

Some of the most popularly seen databases are the Amazon Aurora, Amazon Redshift, and Amazon RDS, which are relational databases, and use SQL (Structured Query Language ) to manipulate data stored in tabular formats. Amazon DynamoDB, on the other hand, is a NoSQL database that stores data in the form of key-value pairs. To learn more about NoSQL, take up NoSQL courses and enhance your knowldge about the same.

Amazon ElasticCache is an in-memory database where most of the memory is stored in the RAM.

Let’s now look into these in further detail to understand these databases’ applications better.

Popular AWS Databases

Now that we’ve understood what AWS databases are and their many benefits, let us talk about some of the most popular AWS Databases.

RDS (Relational Database Service)

Relational Database Service (RDS) is a fully managed service provided by AWS. It allows users to set up, manage and monitor a database in the cloud. Seven engines are provided by the service to choose from MySQL, MariaDB, Oracle, and SQL Server, and these engines provide support for DBMSs like MySQL.

Benefits of Amazon RDS

  • It is a highly scalable Relational DBMS that allows for high performance in the Infrastructure.
  • A sizeable global infrastructure with multiple availability zones and replication capabilities provides highly available service provisioning.
  • Auto maintenance and upgrades aid in ease of use of the services from a management standpoint.
  • Auto backup and restore capabilities lead to increased consistency and durability of customer data.


Amazon Redshift is a petabyte-scale data warehousing service provided by Amazon and is a fully managed service. It allows us to interpret data to gain more insight into the business and customers. It offers query performance using SQL-based tools and business intelligence applications, regardless of data set size.

Benefits of Amazon Redshift

  • Allows us to perform the execution of parallel queries across multiple system nodes.
  • Provision of auto-Backup on Amazon S3.
  • It is more cost-efficient when compared to other competitive data warehouse services.
  • Provision of built-in security in the form of end-to-end encryption and user-configurable firewall rules.


Amazon Aurora is another Relational Database Engine, fully managed by AWS and compatible with MySQL and PostgreSQL. It has better performance capabilities than most commercial databases, with throughput capability of up to five times when compared to MySQL and three times when compared to PostgreSQL. It is a high-performance storage subsystem with scaling capabilities limited to 128 tebibytes per cluster. Aurora has auto clustering and standardizing capabilities that ease the challenge of database configuration and administration. 

Benefits of Amazon Aurora

  • It’s a highly scalable managed database service with a high throughput compared to other databases.
  • Provides security due to the implementation of end-to-end security.
  • Highly durable and available services.
  • AWS fully manages it as a part of the Amazon RDS suite.


Amazon DynamoDB is a NoSQL database service fully managed by the AWS cloud. It provides fast, predictable, and seamlessly scalable performance. It aids businesses by offloading operating and scaling burdens in a distributed database. It provides managed security, backup, and recovery services, in a highly available and durable manner. 

Being a non-relational database system, there are three main components of a database in DynamoDB. 

  1. Table: Non-structure collection of data, with a fixed number of rows and columns.
  2. Items: contain a group of uniquely identifiable attributes.
  3. Attributes: data elements that reside in each item and are equivalent to a cell in a relational database table.


Benefits of Amazon DynamoDB

  • It is easy to set up and manage the NoSQL Database service.
  • Provides auto-replication of data across multiple availability zones in the global infrastructure.
  • Secure due to provision of encryption at rest.
  • Provision for on-demand Backup and restoration capabilities.


Amazon Elasticache is an easy-to-setup, managed, and scalable web service provided by AWS as a part of its database services. It can be used for caching data in order to accelerate applications and performance. It will also come in handy as primary data for applications where data durability is not a priority. Amazon Elasticache is fully compatible with Redis and Memcached.

Benefits of Amazon ElastiCache

  • Reduced response time since Elasticache retrieves data from an in-memory system.
  • Reduced dependency on disk-based databases.
  • Auto-scaling and extremely elastic; scales up and down as per application requirements.
  • Fully-managed services, so all administrative tasks (backup and recovery, provisioning, etc.) are automated.


With this, we come to the end of the AWS Database blog. We have attempted to brief you about the various database services Amazon provides. Hope you now have a basic understanding of it and would be able to utilize this knowledge fully whenever it’s required. You can also learn about various AWS Certifications and understand if it’s something you can benefit from.

System Databases in SQL Server


In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

AWS Cost Allocation Tags and Cost Reduction

Bob had just arrived in the office for his first day of work as the newly hired chief technical officer when he was called into a conference room by the president, Martha, who immediately introduced him to the head of accounting, Amanda. They exchanged pleasantries, and then Martha got right down to business:

“Bob, we have several teams here developing software applications on Amazon and our bill is very high. We think it’s unnecessarily high, and we’d like you to look into it and bring it under control.”

Martha placed a screenshot of the Amazon Web Services (AWS) billing report on the table and pointed to it.

“This is a problem for us: We don’t know what we’re spending this money on, and we need to see more detail.”

Amanda chimed in, “Bob, look, we have financial dimensions that we use for reporting purposes, and I can provide you with some guidance regarding some information we’d really like to see such that the reports that are ultimately produced mirror these dimensions — if you can do this, it would really help us internally.”

“Bob, we can’t stress how important this is right now. These projects are becoming very expensive for our business,” Martha reiterated.

“How many projects do we have?” Bob inquired.

“We have four projects in total: two in the aviation division and two in the energy division. If it matters, the aviation division has 75 developers and the energy division has 25 developers,” the CEO responded.

Bob understood the problem and responded, “I’ll see what I can do and have some ideas. I might not be able to give you retrospective insight, but going forward, we should be able to get a better idea of what’s going on and start to bring the cost down.”

The meeting ended with Bob heading to find his desk. Cost allocation tags should help us, he thought to himself as he looked for someone who might know where his office is.

How To Unite AWS KMS with Serverless Application Model (SAM)

The Basics

AWS KMS is a Key Management Service that let you create Cryptographic keys that you can use to encrypt and decrypt data and also other keys. You can read more about it here.

Important points about Keys

Please note that the customer master keys(CMK) generated can only be used to encrypt small amount of data like passwords, RSA key. You can use AWS KMS CMKs to generate, encrypt, and decrypt data keys. However, AWS KMS does not store, manage, or track your data keys, or perform cryptographic operations with data keys.

You must use and manage data keys outside of AWS KMS. KMS API uses AWS KMS CMK in the encryption operations and they cannot accept more than 4 KB (4096 bytes) of data. To encrypt application data, use the server-side encryption features of an AWS service, or a client-side encryption library, such as the AWS Encryption SDK or the Amazon S3 encryption client.


We want to create signup and login forms for a website.

Passwords should be encrypted and stored in DynamoDB database.

What do we need?

  1. KMS key to encrypt and decrypt data
  2. DynamoDB table to store password.
  3. Lambda functions & APIs to process Login and Sign up forms.
  4. Sign up/ Login forms in HTML.

Lets Implement it as Serverless Application Model (SAM)!

Lets first create the Key that we will use to encrypt and decrypt password.

    Type: AWS::KMS::Key
      Description: CMK for encrypting and decrypting
        Version: '2012-10-17'
        Id: key-default-1
        - Sid: Enable IAM User Permissions
          Effect: Allow
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:root
          Action: kms:*
          Resource: '*'
        - Sid: Allow administration of the key
          Effect: Allow
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:user/${KeyAdmin}
          - kms:Create*
          - kms:Describe*
          - kms:Enable*
          - kms:List*
          - kms:Put*
          - kms:Update*
          - kms:Revoke*
          - kms:Disable*
          - kms:Get*
          - kms:Delete*
          - kms:ScheduleKeyDeletion
          - kms:CancelKeyDeletion
          Resource: '*'
        - Sid: Allow use of the key
          Effect: Allow
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:user/${KeyUser}
          - kms:DescribeKey
          - kms:Encrypt
          - kms:Decrypt
          - kms:ReEncrypt*
          - kms:GenerateDataKey
          - kms:GenerateDataKeyWithoutPlaintext
          Resource: '*'

The important thing in above snippet is the KeyPolicy. KMS requires a Key Administrator and Key User. As a best practice your Key Administrator and Key User should be 2 separate user in your Organisation. We are allowing all permissions to the root users.

So if your key Administrator leaves the organisation, the root user will be able to delete this key. As you can see **KeyAdmin **can manage the key but not use it and KeyUser can only use the key. ${KeyAdmin} and **${KeyUser} **are parameters in the SAM template.

You would be asked to provide values for these parameters during SAM Deploy.
