AWS IAM—Key Features:
We should consider IAM as the initial move towards making sure about all your AWS
administrations and assets:
➢ Confirmation: AWS IAM issue and empower verification for assets, individuals,
administrations, and applications inside your AWS account.
➢ Approval: Access to the executives or approval in IAM is made of two essential
segments: Policies and Permissions.
➢ Fine-grained consents: Business group in your association admittance to charging
data, yet in addition need to permit the engineering group full admittance to the EC2
administration.
➢ Common admittance to AWS accounts: Most associations have more than one AWS
account, and now and again need to designate access between them.

AWS Lambda:
AWS Lambda is a serverless compute service provided by Amazon Web Services (AWS)
that allows users to run code without provisioning or managing servers.
➢ AWS Lambda cloud service that runs your code only when needed. You upload your
code, and AWS takes care of everything else like scaling, security, and availability.
➢ The two key terms to understand are:
❖ Serverless: This doesn't mean there are no servers. AWS
handles all the provisioning, patching, scaling, and
maintenance.
❖ Event-Driven: Lambda functions don't run all the time.
They sit idle until they are triggered by an event.

Amazon Virtual Private Cloud (VPC):
Allows users to provision a logically isolated section of the AWS Cloud where they can
launch AWS resources in a virtual network defined by them.
➢ AWS VPC is a private subsection of AWS in which you can place AWS resources such
as EC2 instances and databases.
❖ It gives all the benefits of the traditional network
that you have for your own data center.
❖ It gives the benefit of scalable infrastructure in the
AWS environment.
❖ It gives you complete control over your virtual
network.

Dr. K. Adisesha
27
Amazon Route 53:
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS)
web service provided by AWS that translates human-readable domain names into IP
addresses to connect users to internet applications.
➢ DNS resolution: Converts domain names (e.g., www.example.com) into IP addresses,
enabling users to access your web applications.
➢ Traffic routing: Directs user traffic to the correct
servers or endpoints, whether they are running
within AWS or elsewhere.
➢ Domain registration: Allows you to register new
domain names directly through the service.

Dr. K. Adisesha
28
Amazon CloudFront:
Amazon CloudFront is a global content delivery network (CDN) service from AWS that
speeds up the distribution of static and dynamic web content, like HTML, CSS,
JavaScript, and images, to end users.
➢ CloudFront also enhances security by protecting against various attacks and
integrating with other AWS security services.
➢ Edge locations: CloudFront uses a global network of data
centers called edge locations to store copies of your content.
➢ Cache and delivery: If the content is in the cache, it's served
directly from the edge location. If not, CloudFront fetches it
from the origin and caches it for future requests.

Dr. K. Adisesha
29
Elastic Load Balancing (ELB):
Automatically distributes incoming application traffic across multiple targets, such as
EC2 instances, containers, and IP addresses, in one or more Availability Zones.
➢ Automatic scaling: It can automatically increase or decrease its capacity to handle
varying amounts of incoming traffic.
➢ Distributes traffic: It accepts incoming traffic and forwards it to a group of registered
targets.
➢ Monitors health: It performs regular health checks on
the registered targets.
➢ Routes to healthy targets: If a target is unhealthy, the
load balancer stops sending traffic to it and routes
traffic to other healthy targets instead.

➢ Amazon CloudFront: A fast content delivery network (CDN) service that securely
delivers data, videos, applications, and APIs to customers globally with low latency and
high transfer speeds.
➢ Amazon Route 53: A highly available and scalable cloud Domain Name System (DNS)
web service.
➢ AWS Direct Connect: Establishes a dedicated network connection from on-premises to
AWS, offering consistent network performance.

Content Delivery Network(CDN)
Dr. K. Adisesha
31
➢ When a user requests content from a website with a CDN, the CDN identifies the user's
location and routes the request to the nearest edge server.
➢ The edge server, which stores cached copies of the website's content, quickly delivers
the requested content to the user.

Content Delivery Network(CDN):
➢ Amazon CloudFront: A fast content delivery network (CDN) service that securely delivers
data, videos, applications, and APIs to customers
globally with low latency and high transfer speeds.
➢ Amazon Route 53: A highly available and scalable
cloud Domain Name System (DNS) web service.
➢ AWS Direct Connect: Establishes a dedicated
network connection from on-premises to AWS,
offering consistent network performance.

Dr. K. Adisesha
33
Content Delivery Network(CDN):
The CDN helps to offload traffic from the origin server, reducing the risk of server
overload and ensuring consistent performance even during traffic spikes.
➢ CDNs can be classified into several types based on their architecture and functionality:
❖ Public CDNs
❖ Private CDNs
❖ Peer-to-Peer (P2P) CDNs
❖ Hybrid CDNs
❖ Push CDNs
❖ Pull CDNs

Dr. K. Adisesha
34
CDNs can be classified into several types based on their architecture and functionality:.
➢ Public CDNs: Any CDN that is accessible to everybody online is referred to as a public CDN.
❖ These CDNs are used to swiftly and effectively provide content, including pictures, movies,
and other static files, to users. For example: Cloudflare, Akamai, and Amazon CloudFront.
➢ Private CDNs: A CDN that is only utilized by one firm or organization is a private CDN.
❖ These CDNs are used to distribute content to internal users or clients, and they are frequently
set up on a private cloud or within an organization's own infrastructure.
❖ For example: Google Cloud CDN, Netflix Open Connect.
➢ Peer-to-Peer (P2P) CDNs: These CDNs utilize peer-to-peer networking technology to distribute
content directly between users, reducing reliance on centralized servers.
❖ For example: BitTorrent, webTorrent.

Dr. K. Adisesha
35
CDNs can be classified into several types based on their architecture and functionality:.
➢ Hybrid CDNs: A hybrid CDN combines elements of both public and private CDNs.
❖ In a hybrid CDN, some content is delivered using a public CDN, while other content is
delivered using a private CDN. For example: Microsoft Azure CDN
➢ Push CDNs: In a push CDN, content is uploaded or "pushed" to the CDN's servers in advance of
when it is needed.
❖ Push CDNs are often used for caching large files or content that is not frequently updated.
❖ For example: KeyCDN, CDN77
➢ Pull CDNs: In a pull CDN, content is requested or "pulled" from the CDN's servers when it is
needed.
❖ Pull CDNs are often used for delivering dynamic content, such as web pages or API
responses. For example: Amazon CloudFront, Cloudflare

➢ Through the use of multiple
artificial intelligence and machine
learning (AI/ML) services, you can
submit a photo and an image
caption will be read back to you in
a clear, natural-sounding voice in a
variety of languages and dialects.

Web App for Visually impaired:
Web app uses the AWS Cloud to help the visually impaired review images.
➢ AWS Amplify distributes the web app, consisting of HTML, JavaScript, and CSS, to your mobile device.
➢ The Amazon Cognito identity pool grants temporary access to the Amazon Simple Storage Service (Amazon
S3) bucket.
➢ The user uploads an image file to the Amazon S3 bucket using an AWS SDK through the web app.
➢ The web app invokes the backend AI services by sending the Amazon S3 object key in the payload to
Amazon API Gateway.
➢ API Gateway instantiates an AWS Step Functions workflow. The state machine orchestrates the AI/ML
services Amazon Rekognition, Amazon SageMaker AI, Amazon Textract, Amazon Translate, and Amazon
Polly using AWS Lambda functions.
➢ The Step Functions workflow creates an audio file as output and stores it in Amazon S3 in MP3 format.
➢ A pre-signed URL with the location of the audio file stored in Amazon S3 is sent back to your browser
through Amazon API Gateway. Your mobile device plays the audio file using the pre-signed URL.
