What is AWS and How it Works?

Description of the image

In the current era, you can only enter the field of cloud computing if you are skilled in AWS. Why is that so? Without any doubt, Amazon Web Services is the biggest cloud computing giant in the world. Azure and Google Cloud are trying to catch up with AWS.

However, there are multiple reasons why AWS is at the top of its race, including versatility, scalability, and a wide range of other benefits. 

What is Amazon Web Services (AWS)?

Amazon Web Services, as the name indicates, is a cloud storage and computing platform owned by Amazon. Under the umbrella of AWS, Amazon offers hundreds of cloud services and solutions - it is currently the world’s largest cloud solutions platform in terms of market share.

AWS offers three main types of services:

  1. EC2 - Amazon Elastic Compute Cloud, or EC2, is a web service by AWS that offers cloud solutions and makes web-scale cloud computing easier for developers.
  2. Glacier - Amazon S3 Glacier is a web service that has multiple classes that can be used for data archiving.
  3. S3 - Amazon Simple Storage Service, or S3, makes data storage efficient and easy for businesses.

AWS offers a mixture of Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and packages Software-as-a-Service (SaaS). The platform provides both hardware and software services - all you have to do is log in to the AWS portal and access the different services you want.

It is not just businesses that use AWS solutions - government agencies, non-profit organizations, educational institutions, etc., that use these cloud computing and storage services. AWS is so popular among everyone in need of cloud solutions because it offers a comprehensive set of solutions that include, but are not limited to, compute power, database storage, content delivery, and effect functionality.

How does AWS Work?

AWS has a plethora of services and solutions that can be sorted into different categories. Let us take a look into some of these categories here.

Databases and Data Management

Amazon Relational Database Service (RDS) is a relational database management system. With database engines like MySQL, Oracle, PostgreSQL, and SQL Server, Amazon RDS acts as the perfect platform for creating, maintaining, and updating databases.

The most convenient thing about Amazon RDS is that you can create and maintain databases that fit the needs of your business or institution. The platform lets you work efficiently with vast chunks of data, making maintaining databases easy and effective. 

AWS has an excellent architecture system that balances both security and efficiency. Due to this functionality, AWS is a great database management system that can create secure web applications and storage facilities.  

Storage Services

Here, we again mention the Amazon S3 service - Simple Storage Service, a highly available and reliable storage system that lets users add, access, and retrieve any data from anywhere. S3 has great applications in fields like Big Data, Machine Learning, and Natural Language Processing. 

Due to its robustness, connectivity to other AWS services, and security reasons, S3 is preferred by businesses, big and small, all over the world. Apart from storage and big data, S3 is also used for data archiving, backup and recovery, and hosting static websites.

Hybrid Cloud

Hybrid cloud refers to the new development in cloud computing and storage that combines two or more types of cloud infrastructures to enable efficient cloud storage for different purposes in the same organization. The AWS hybrid cloud services offer security, storage, networking, and a wide range of other solutions - this is done by creating hybrid architectures that specifically support your organization’s needs.

AWS hybrid cloud services can be an excellent solution for businesses with varying customer needs and solutions - the hybrid cloud can offer you the perfect package to meet all the requirements. It also improves infrastructure security and productivity.

Some Popular Platforms that Use AWS

From Spotify to Netflix, hundreds of popular platforms and businesses have adopted AWS solutions. Here are a select few:

  • Airbnb
  • LinkedIn
  • Pfizer
  • Twitter
  • Kellog’s
  • The Guardian

Why Choose AWS Over Other Cloud Services Providers?

Simply put, AWS is one of the best cloud platforms in existence today. This is due to their robust architecture, efficient data management, strong security features, and a lot more. Here are a few reasons why businesses choose to adopt AWS solutions for their requirements:


The main reason why AWS is preferred by businesses across fields and industries is because these services can be tailored to fit the specific needs of a business. Customized solutions are the need of the hour, and you can access these solutions efficiently with the strong suite of tools and services AWS has to offer.

High-Performance and Scalability

Optimal running of your applications is crucial to maintain business. This is made easy with AWS features like auto-scaling and load balancing. AWS also boasts several useful services like CloudFront, Elastic Load Balancing, Virtual Private Cloud, etc., that can optimize and promise quick and safe delivery of solutions.

Comprehensive Suite

Perhaps the best part of AWS is the comprehensive suite of cloud solutions and services that you can access. AWS offers a pre-built set of tools and applications for developers that makes it very easy and efficient for them to quickly and securely build cloud solutions as per the needs of their clients.

With these tools, developers can design solutions that can be added directly to the existing infrastructure of a business to run it more effectively.
