What is AWS Architecture

Amazon Online Services, also known as AWS, develops cloud services to manage heavy website traffic as well as the enormous volume of generated data every day by apps or websites. The AWS architecture ensures that users are developing and maintaining cloud solutions in accordance with industry guidelines, standards, and recommendations. In this article, we will discuss AWS architecture, its working, the key components of AWS architecture as well as its importance.

AWS Architecture

The cloud services developed by Amazon Web Services also termed AWS, are extensively used by businesses, start-ups, and government organizations. Video storage and large data storage assist organizations in maintaining excessive traffic. The primary function of the AWS EC2 architecture is to provide customers with access to a variety of virtual machines with varying settings. Generally, EC2 meaning Elastic Compute cloud offers a high range of pricing options, configuration options, and the ability to map specific machines, among other things.

How does the AWS Architecture work?

Let us understand the working of AWS architecture with the help of a simple diagram given below:

How does the AWS Architecture work

It is viewed as the fundamental framework of the AWS EC2 or AWS architecture system. EC2 enables clients or users to use different settings in their own methods or projects in accordance with their needs. Additional wonderful options include pricing choices, customized server mapping, server setup, etc. The Simple Storage Services component of AWS is known as S3. Users of this S3 can quickly get or store data using different data types by making calls to the Application Programming Interface. Additionally, there won't be any computational element to the services.
Talking about the dynamic scaling policies, the user is able to add or delete instances as well as increase or decrease scale. We reduce latency with the aid of Amazon CloudFront distribution. Additionally, it keeps up the edge sites throughout the world, which serve as caches for streaming and web content. On the other hand, our Internet domain is registered and managed with the help of the Route 53 domain service.

Key Components of AWS Architecture 

Amazon API Gateway :

In order to construct, maintain, publish, protect as well as monitor the APIs at any size, developers can use the fully managed service known as Amazon API Gateway. Applications use APIs as their "front door" to data, business logic, or functionality in your backend services.

These are the main features of Amazon API Gateway:

  • Monitoring API activity is simple
  • Strong security control.
  • Simple servers.
  • Only what is used must be paid for by the users.
  • Performance that is effective at both large and small scales.

AWS Lambda :

The serverless compute service AWS Lambda executes the user's code in response to situations and manages the basic compute resources for the user automatically. These can be updates or status changes, like when a customer adds something to their shopping basket on an e-commerce platform.Writing the codes is the sole work needed to make Lambda function. Because consumers only have to pay for the time their codes are running, it is economical. There isn't any requirement for learning another programming language because it is rather simple to utilize.

Amazon Simple Email Service : 

An affordable email service called SES meaning Amazon Simple Email Service is based on the scalable and dependable infrastructure created by Amazon.com to serve its own clientele. You may send your customers transactional emails, marketing emails, and any other form of quality content using Amazon SES.

Load Balancing :

There are two types of load balancing :
Elastic Load Balancing
The load balancing element of the AWS architecture contributes to the proper improvement of the application and server's efficiency. The Hardware load balancer is utilized as a standard network appliance that aids in the functionality of typical we
Hardware Load Balancingb application designs, commonly referred to as Hardware Load Balancing. Additionally, it ensures that the Elastic Load Balancing is delivered, and AWS distributes traffic to EC2 instances from a variety of sources. Additionally, it distributes traffic to dynamically added hosts and Amazon EC2 hosts that have been dropped by the rotation of load balancing.

Elastic Load Balancing :

Simplifying part of the traffic and supporting sticky sessions to offer improved routing services, helps to minimize as well as increases the capacity of load balancing.

Amazon CloudFront :

The majority of the time, information that is immediately used for web distribution is sent through Amazon CloudFront. The information present there can be of various types, including dynamic, static, as well as streaming content utilizing several worldwide network locations. From the user's perspective, the material can be automatically requested based on the closest location, which also demonstrates the varied impact on the performance that will be improved with the proper method. The contracts and monthly payments carry no obligations.

Security Management :

The component of the architecture known as security groups serves as an internal firewall to give the architecture the necessary security. It details the source IP range, protocols, and ports that connect to the system of EC2. The security group's access to EC2 can also be restricted by configuring it using subnets or IP addresses.

Elastic Cache :

An effective online service that makes it simple to manage the memory cache in the cloud is Amazon Elasticache. In addition to being essential for memory management, this cache will stably lower the demand for the service. By caching the data that is frequently accessed, it also makes sure to improve the scalability as well as performance on the database tier.

Amazon RDS :

Similar to MySql, Amazon RDS helps deliver access (Microsoft SQL Server). These programs, queries, and resources will also be helpful with Amazon RDS.

Importance of AWS Architecture 

The main benefit of AWS architecture is its powerful drawing capabilities, an abundance of Amazon-pre-designed icons, and a variety of straightforward iconography are all utilized to create AWS architectural diagrams, which are widely used for improving solutions. Let us see a few more importance :

  • Amazon's pre-built icons and effective sketching tools are used to construct the AWS architecture.
  • The AWS architecture ensures excellent services that follow web standards.
  • Because AWS resources are accessible everywhere, they can meet the needs of customers anywhere in the world.

Types of Deployment Models in Cloud Computing

Public Cloud : It is utilized when a network deployment is made accessible to the general public. Companies with dynamic and ever-expanding demands choose to adopt this.

Private Cloud : Public cloud is less secure than the private cloud. Companies who need to back up their data internally with firewalls employ it. The data is then hosted either internally or externally depending on the needs of the business.

Community Cloud : Different businesses or organizations that are based in the same area or neighborhood share this cloud concept. Sharing the cloud is done manually. For instance, banks employ the establishment of the community cloud.

Hybrid Cloud : Both private as well as public clouds combine to create hybrid clouds. Internal or external suppliers give the resources. Organizations that demand high security and scalability opt for hybrid clouds, which let them store the data in a private cloud while interacting with customers in the public cloud.

AWS Cloud Computing Models

AWS Cloud Computing Models


IaaS stands for Infrastructure as a Service, is a subset of cloud computing that gives users online access to a virtualized environment with computer resources. It offers storage, network connectivity for clients, as well as demand processing. This paradigm controls the management of networking, storage, and server infrastructures. On top of these resources, clients can create their own versions of the application.


The Platform in General A platform where clients can create, run, and administer any kind of application is provided by a service model. Clients may receive PaaS through hybrid, private, or public clouds. This approach provides services like emails, databases, waiting lists, engine workflow, etc. According to this approach, improved resource functionality is the responsibility of cloud service providers.


Software as a Service, or SaaS, is defined as a model used for cloud computing in which effective Internet deployment allows for the use of applications as services. This concept aids clients in getting rid of cumbersome software and hardware administration procedures. Additionally, they are permitted to change a few elements, such as the color of their brand's logo, etc.

Advantages of AWS

Economical : Because AWS allows users to only pay for the services they really use, it is substantially more affordable. Additionally, installing and configuring pricey hardware will cost money if we decide to build a physical server. Therefore, it is preferable to use cloud services, particularly AWS, which are both dependable as well as affordable.

Reliability : AWS is quite dependable because it offers year-round, round-the-clock service. The hosted apps and services are readily switched to other servers automatically, so even if one of the servers fails, they will still be accessible.

Backup and Recovery : Compared to storing data on a physical device, AWS makes it simpler to back up, store, as well as restore data. Nowadays, mostly all service providers have the capability to recover all data in the event of a data loss, making it appropriate and beneficial for all industries.

Limitless Storage Capacity : Consumers frequently worry about storage capacity, however, AWS offers nearly unlimited storage, so users do not have to spend any additional money for storage. They are given unlimited storage.

Easier Information Access : Users have access to their data after doing the registration on the service platform of AWS cloud from anywhere in the globe as long as they have a reliable Internet connection. However, these amenities change depending on the type of account or plan chosen.

Disadvantages of AWS

Technical Issues : Every day without fail, AWS offers services to a large number of consumers. The system may occasionally encounter a major issue, which would temporarily stop a company's business operations.

Security Issues : When using cloud services, businesses prioritize security the most because keeping crucial data and files safe is never a simple task. There is a possibility that hackers will gain access to the system.

Having Trouble Changing Service Providers : When businesses want to migrate to another cloud service, cloud service providers offer full confidence about their services, but it is highly challenging for them to integrate the present cloud apps into a new service cloud platform.
