What is AWS?

The full form of AWS is Amazon Web Series. AWS is a platform that allows users to access on-demand services like a virtual cloud server, database storage, etc. It uses distributed IT infrastructure for providing various IT resources. It offers services like packaged software as a service(SaaS), Platform as a Service(PaaS), and Infrastructure as a Service(IaaS).

AWS Basics

What is Cloud Computing

Cloud Computing is a computing service in which big groups of remote servers meshed to enable centralized data storage and online access to computer resources or services. Following are the types of clouds:

Public Cloud

In the public cloud,  extrinsic service providers make services and resources accessible to the users through the internet.

Private Cloud

Private cloud offers approximately the same features as public cloud, but organizations or third parties manage the services and data. In this type of cloud, the main focus is Infrastructure.

Hybrid Cloud

A hybrid cloud is a combination of public cloud and private cloud. According to the sensitivity of the applications and data, we use the Public cloud and private cloud.

AWS Advantages

Following are the advantages of AWS:

  • AWS enables organizations to use popular operating systems, programming models, architectures, and databases.
  • AWS is a cost-efficient service that enables us to pay only for what we use. 
  • We do not need to pay money for maintaining and running data centers.
  • AWS provides rapid deployments.
  • AWS provides distributed management and billing.
  • Through AWS, we can deploy our applications in multiple regions throughout the world with just a few clicks.

What are the features of AWS?


AWS flexibility enables us to select suitable programming languages, models, and operating systems. Therefore we do not need to learn the latest skills for adopting the latest technologies. The flexibility of AWS allows us to migrate the applications to the cloud easily. AWS flexibility is a huge asset for the organizations for delivering the product with upgraded technology.

Scalable and Elastic

In the conventional IT organization, we calculate scalability and elasticity with infrastructure and investment. Scalability is the ability to scale the computing services down or up when demand decreases or increases respectively.


Cost is one of the key factors that must be considered in providing IT solutions. Cloud offers an on-demand infrastructure that allows us to use the resources that you genuinely require. In AWS, we are not restricted to a group of resources like computing, bandwidth, and storage resources. AWS does not have any long-term commitment, upfront investment, or minimum speed.


AWS offers a scalable cloud computing platform that gives customers end-to-end privacy and end-to-end security. AWS integrates the security into services and documents for explaining how to utilize the security features.


AWS cloud offers levels of security, privacy, reliability, and scalability. AWS continues to help its customers by improving infrastructure capabilities. AWS has developed an infrastructure according to the lessons taught from the past.

How to Create an Account in AWS?

AWS offers a free account for one year for using and learning different components of AWS.  Through an AWS account, we can access AWS services like S3, EC2, etc.

Step1: For creating an AWS account,  we have to open the link:

After opening the above link, enter the details and sign-up for a new account.

If you already have an account, then we can sign in through Email and password.

Create An AWS Account

Step2: After entering the E-mail, fill the form. Amazon utilizes this information for invoicing, identifying, and billing the account. After account creation, sign-up for the required services.

Contact Information

Step3: To Login for the services, we provide the payment information. Amazon implements a minimum amount of transactions against the card over the file for checking that it is true. This charge differs with the region.

Step4: Next, we perform identity verification. Amazon performs a call back for verifying the given contact number.

Step5: Select a support plan from the plans like Basic, Business, Enterprise, or Developer. The basic plan costs less and has very limited resources, which is helpful to get acquainted with AWS.

Step6: The last step is confirmation. Press the link to log in and switch to the AWS management console.

Amazon Web Services Sign Up

AWS Account Identifier

AWS allocates two unique IDs to every AWS account:

  • AWS account ID
    AWS account ID is a 12-digit number, and we use it for constructing Amazon Resource Names(ARN). AWS account ID helps us to differentiate the resources from the resources of other AWS Accounts.
  • Conical String User ID
    Conical String User ID is a large string of alphanumeric characters like 1234abcde123. We use this ID in the Amazon S3 bucket policy for cross-account access, i.e., for accessing the resources of another AWS account.

AWS Compute Services


What is AWS EC2?

AWS Elastic Compute Cloud is a web service interface that offers scalable compute capability in the cloud. EC2 minimizes the time needed to get and restart the latest user instances to minutes instead of older days. If you want a server, then you have to put a purchasing order and perform cabling for getting a new server which is an extremely time-consuming process.
According to the computing requirement, we can scale the compute capacity down and up. AWS EC2 offers the developers the development of robust applications that separate themselves from general scenarios. 

Creating an EC2 Instance

  • Log in to the AWS management console. Press the EC2 service. Press the launch instance button for creating the new instance.

When we use Lambda

Lamda is a convenient compute service for several application scenarios until we can run our application code through the Lambda standard runtime environment and among the resources that Lamda offers. While using Lambda, you will be responsible

only for your code. Lambda handles the compute fleet that provides a memory balance, network, CPU for running our code.  

AWS Lambda Features

Following are the important features of AWS Lambda:

  1. Concurrency and Scaling controls
    Concurrency and Scaling controls like provisioned concurrency and concurrency limits provide you with fine-grained control over the responsiveness and scaling of our applications.
  2. Code Signing
    For AWS Lambda, Code signing offers integrity and trust controls to check that developers execute only unmodified code in our Lambda functions.
  3. Functions are defined as a container 
    We use our desired container image tooling, dependencies, and workflows for building, deploying and testing our lambda functions.
  4. Lambda Extensions
    We use Lambda extensions for extending our Lambda functions. For instance, we use extensions to integrate the Lambda with our preferred tools to monitor governance and security.

Creating a Lambda Function

What is Cloudwatch

CloudWatch is a utility that we use to monitor our AWS applications and resources that we run on the AWS in real-time. We use CloudWatch for tracking and collecting the metrics that assess our applications and resources. CloudWatch displays the measures spontaneously about each AWS service that we select.

CloudWatch Terminology

  1. Alarms
    Alarms enable us to set up alarms for notifying you at any time a specific threshold is hit.
  2. Dashboards
    We use CloudWatch for creating dashboards to display what is taking place with our AWS account.
  3. Events
    CloudWatch events allow us to answer state changes to our AWS resources.
  4. Logs
    CloudWatch Logs enable us to monitor, store and aggregate the logs.

AWS Storage Services

What is AWS S3

AWS S3 is a low-cost, high-speed, scalable developed for data archiving, application programs, and online backup. It enables us to download, store, and upload any kind of file up to 5 TB in size. Storage services will allow the subscribers to use the similar systems that amazon utilizes to run its websites. 

How to Configure S3

Following are the steps to configure Amazon S3:

Step 1: Go to the Amazon S3 console

Step 2: Through the following steps, we create the bucket:

  • Press the “Create Bucket” button in the following window.

AWS Storage classes

AWS Storage classes maintain data integrity through checksums. We use storage classes to assist the parallel data loss in multiple facilities. Following are the four types of storage classes:

  1. S3 Standard
    It is a standard storage class that stores the data excessively throughout multiple devices in various facilities. It is developed to maintain the loss of 2 facilities parallely. It offers high throughput performance and low latency.
  2. S3 one zone-infrequent access
    We use the S3 one zone-infrequent access storage class when we access the data less frequently but require fast access when needed. It holds data in a single zone while other storage classes save data in three zones. It is suitable to store the backup data and a perfect option for the less frequently accessed data. It offers lifecycle management for the migration of the objects to the other S3 storage classes.
  3. S3 Standard IA
    IA refers to infrequently accessed. We use Standard IA storage class when we use the data less frequently but need rapid access when required. It is developed to maintain the loss of 2 facilities parallely.  
  4. S3 Glacier
    It is the cheapest storage class, and we can use it for archives only. We can save any volume of data at a lesser cost than the other storage classes. We can load the objects directly to S3 Glacier.

CloudFront CDN

CloudFront CDN is a method of distributed servers that give web content and web pages to a user according to the user’s location, the source of the content delivery server, and the webpage.

Terminology of CloudFront CDN

Distribution: It is the name of the CDN, which contains a group of edge locations. Creating a new CDN in the network indicates that we are creating Distribution.
Origin: It specifies the origin of all the files which CDN will distribute. The origin can be an EC2 Instance, an Elastic Load Balancer, or an S3 bucket.
Edge Location: It is the location where we cache the content. It is the split of an AWS availability zone or AWS region.

How CloudFront CDN delivers content to the users

After we set up CloudFront to deliver our content, here is what happens when users request files:

  • A user accesses our application or website and requests files like an HTML file and an image file.
  • DNS routes that request to CloudFront POP can perfectly serve the request- generally the immediate CloudFront POP in the text of latency- and routes that request that edge location.
  • In the CloudFront POP, CloudFront verifies its cache of the requested files. If the files are available in the cache, CloudFront sends them to the user. If the files are not available in the cache, it performs the following:
    • CloudFront matches the request with the specifications in your distribution and dispatches the request of the files to your origin server for the respective file type.
    • Origin servers return them to the edge location.
    • Once the first byte comes from the origin, CloudFront starts dispatching files to the user.  CloudFront inserts files to cache in edge location for later when someone requests those files.

AWS Snowball

Snowball is a data transport solution that utilizes secure appliances for transferring vast amounts of data out of and into AWS. It is a process of taking the data into AWS and evading the internet. In place of handling all the explicit disks, Amazon offered you a tool, and you loaded a tool with the data.
Snowball addresses general challenges for huge-scale data transfers like long transfer time, security issues, and high network costs. Transferring data through Snowball fast, secure, and accessible. Snowball offers 256-bit encryption, tamper-resistant enclosures, and a Trusted platform module to assure security.

Snowball Edge

Snowball Edge is the 100 TB data transfer device with onboard compute and storage capabilities. It is like an AWS data center that we can bring on-site. We can also use it for moving large amounts of data out of and into AWS.

AWS Network Services


The full form of VPC is Virtual Private Cloud. Amazon VPC offers a coherently separated AWS cloud where we can start AWS resources in the virtual network that we define. We can have full control over our virtual networking environment, comprising a choice of our IP Address range, the configuration of the route tables, and the creation of the subnets.

VPC Architecture

VPC Architecture

Outline represents the region, and the region name is “us-east-1”. Inside the region, we have VPC, and outside VPC, we have a virtual private gateway and internet gateway. Virtual Private Gateway and Internet Gateway are the methods for connecting to the VPC.  Both the connections go to the router in the VPC, and the router directs traffic to the routing table. After that, the routing table will direct the traffic to the Network ACL. Network ACL is a firewall or a security group. Network ACL is a state list that allows and denies the roles.

Uses of VPC

  • Through VPC, we can start the instances in a subnet of our choice.
  • With VPC, we can allocate custom IP address ranges in every subnet.
  • By using VPC, we can set up the route tables between the subnets.
  • It offers the best security control over our AWS resources.
  • We can allocate security groups to the Individual instances.

Creating your Custom VPC

  • First, log in to the .”AWS management console.
  • Press the VPC services in the “Networking and Content Delivery.”
  • Press the “Your VPCs” exist on the left side of the console.
  • Press “Create VPC” for creating our custom VPC.

Create VPC

  • Fill up the details for creating the custom VPC.

Creating The Custom VPC

We have to fill the following fields:

  • Name tag: It is the VPC name that we give to our VPC.
  • IPV4 CIDR block: Build this address as large as possible.
  • IPV6 CIDR block: We can provide an IPV6 CIDR block.
  • Tenancy: It is the default field.

AWS Direct Connect

AWS Direct Connect is a Cloud utility solution that simplifies establishing a reliable network solution from our place to AWS. Through AWS Direct Connect, we can create the connectivity between AWS and our office, data center, colocation environment, which reduces our network costs, increases bandwidth throughput, and offers a consistent network experience than the internet-based connection.

Direct Connect Architecture

Direct Connect Architecture

  1. AWS Region: In the above architecture, we have an AWS region, and in the AWS region, we have public services like S3, VPC.
  2. Direct Connect Location: Direct Connect architecture contains direct connect location, which is spread throughout the world. In the direct connect location, we have two cages: customer or partner cage, AWS cage. AWS cage contains direct connect routers, and Partner/Customer contains Part/Cust routers.

AWS Bastion Host

A bastion Host is a particular purpose computer over a host configured and developed to resist the attacks. The computer hosts one application. For instance, we remove a proxy server and other services for reducing the threat to the computer.  A bastion host is tempered because of its purpose and location, which is in the demilitarized zone or the outside of a firewall.

In the above architecture, we have private and public subnets. NAT instance is available at the backside of the security group, and NAT gateway is available after the security group since we configure the NAT instance with the security group while NAT gateway does not need any security group. When the instance in the private subnet needs to access the internet, they do it by using NAT Gateway or NAT instance.


The full form of AMI is Amazon Machine Images. It is a virtual image that we use for creating the virtual machine in an EC2 instance. Following are the types of AWS AMI:

  1. EBS - backend instances: It is an EC2 instance that offers temporary storage. If we delete the EC2 instance, then the data that exists in the EC2 instance will be deleted. For making the data stable, Amazon offers an EBS volume.
  2. Instance Store - backend instances: In the instance store, the instance contains storage approximately 1 TB or 2 TB, which is transitory storage. Once we terminate the instance, the data will be lost.

AWS Database Services

Amazon DynamoDB

Amazon DynamoDB is also called Amazon Dynamo Database or DDB. It is a NoSQL database utility offered by AWS(Amazon Web services). DynamoDB is famous for its latencies and scalability. According to AWS, DynamoDB reduces costs and eases the storage and retrieval of data.

Advantages of AWS DynamoDB

  1. Scalable
    Amazon DynamoDB scales the resources committed to a table to thousands of servers distributed throughout different availability zones to satisfy our throughput and storage requirements. There are no restrictions to the volume of data every table can store.
  2. Rapid
    Amazon DynamoDB offers great throughput at minimal latency. It is developed on the state drivers to maximize for excellent performance even at a large scale.
  3. Managed
    DynamoDB releases developers from the concerns of providing software and hardware, configuring the distributed database cluster, and handling the cluster operations. It manages all the difficulties of partitions and scaling our data on our machine resources to satisfy our I/O performance needs.
  4. Flexible
    Amazon DynamoDB is a highly flexible system that does not compel its users into a specific consistency model or data model. DynamoDB tables do not contain an established schema but rather enable every data item to contain any type of attribute.
  5. Available and Durable
    Amazon DynamoDB copies its data on at least 3 data centers such that the system continues to work and provides data even under failure cases.

Components of Amazon DynamoDB

Following are the components of the Amazon DynamoDB:

  • Tables: Like other database systems, DynamoDB stores the data in the tables. The table is a collection of data. 
  • Items: Every table contains multiple items. Item is a set of attributes that is solely identifiable amid all the other items. In DynamoDB, we don’t have any restriction to the number of items we can store in the tables.
  • Attributes: Every Item contains multiple attributes. The attribute is an essential data element that does not require to be broken down. For instance, a “People” table has attributes like PersonID, FirstName, LastName, etc.
  • Primary Key: When we create the table, we should define the primary key of the table. The primary key uniquely determines every table item, such that no two items can have a similar key.

Amazon Redshift

Redshift is a rapid and robust, completely managed, and petabyte-scale data warehouse utility in the cloud. We use Redshift for only $0.25 per hour with no upfront costs or commitments and the extent to a $1,000 terabyte per year. Redshift contains two kinds of nodes:

  1. Single node: A single node can store up to 160GB.
  2. Multi-node: Multi-node contains multiple nodes. It is two types:
    1. Leader Node
      It handles the client connections and accepts queries. Leader node accepts queries from client applications, analyses the queries, and builds the execution plans. It aligns with the concurrent execution of those plans with the compute code and integrates the intermediate results of the nodes.
    2. Compute Node
      A compute node runs the execution plans, and after that, we send the intermediate results to the leader node for aggregation before dispatching them to the client application.

AWS Analytics Services

Amazon Elastic MapReduce

Amazon EMR is a cluster platform that streamlines executing big data frameworks like Apache Hadoop, Apache Spark on the AWS for processing and analyzing vast amounts of data. Through these frameworks and associate freeware projects like Apache Pig and Apache Hive, we can process the data for the analytics intents and the business intelligence workloads. Following are the advantages of AWS Elastic MapReduce:

  1. Cost savings
    Amazon ECR pricing relies on the type of instance and the number of EC2 instances that we implement, and the region in which we start our cluster.
  2. AWS Integration
    Amazon EMR(Elastic MapReduce) integrates with the other AWS services for providing functionalities and capabilities associated with the storage, networking, security, etc., for our cluster.
  3. Deployment
    Our EMR Cluster contains EC2 instances that carry out the work we submit to our cluster. When we start our Amazon EMR, the cluster setups the instances with applications that we select, like Apache Spark or Hadoop. 
  4. Reliability
    Amazon Elastic MapReduce(EMR) supervises nodes in our cluster and systematically terminates and substitutes the instance in case of failure. Amazon EMR delivers configuration options that handle if our cluster is ended manually or automatically. If we configure our cluster to be automatically ended, it is ended after all the steps finish.

Uses of AWS EMR(Elastic MapReduce)

Following are the uses of AWS EMR:

  1. Real-time Analytics: Users can process and use real-time data. We can perform the streaming analysis in a fault-tolerant way and submit the results to Amazon HDFS or S3.
