What Is AWS Cloud Computing?


Everyone must have heard about AWS Cloud Computing directly or indirectly. Amazon Web Services (AWS) is Amazon’s comprehensive Cloud Computing marketplace. Today, organizations are mainstreaming Cloud Computing as all firms of diverse sizes and industries use it for various use cases, including data backup, email, software development, disaster recovery, virtual desktops, testing, and big data analytics. It is also used in customer-facing web applications. Many healthcare organizations are utilizing the cloud to provide more patient-specific treatments. Companies that provide financial services utilize the cloud to support real-time fraud prevention and detection. Additionally, video game developers distribute online games to millions of players worldwide via the cloud.

Now, let’s answer the main question: what is AWS Cloud Computing? 

What Is AWS? 

In 2006, Amazon Web Services (AWS) started providing organizations with web services for IT infrastructure, now called Cloud Computing. One of the main advantages of Cloud Computing is the ability to replace upfront capital infrastructure costs with low variable costs that grow with your organization.

Amazon’s Cloud Computing platform, AWS (Amazon Web Services), is extensive and constantly expanding. It combines infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and packaged software-as-a-service (SaaS) products. An enterprise may benefit from AWS services by receiving tools like computing power, database storage, and content delivery services. 

The internal infrastructure that Amazon.com constructed to conduct its online retail activities served as the foundation for the initial web services that Amazon.com Web Services offered in 2002. It started providing its distinguishing IaaS services in 2006. One of the first businesses to offer a pay-as-you-go Cloud Computing model that scales to meet users’ demands for computation, storage, or throughput was Amazon Web Services (AWS). 

For businesses and software developers, AWS provides a wide range of tools and solutions that may be used in data centers in as many as 190 nations. AWS services are available to organizations like governmental bodies, academic institutions, non-profits, and for-profit businesses.

How AWS Became What It Is Now? 

It all started in the early 2000s when the business sought to introduce Merchant.com, an e-commerce service, to assist independent retailers like Target or Marks & Spencer in creating online shopping portals based on Amazon’s e-commerce platform. Because it didn’t really plan properly for future requirements when it began in 1994, like many companies, it turned out to be far more expensive than they had anticipated to create an external development platform. They had unintentionally produced a disorganized environment for development rather than a well-organized one. The separation of the numerous services to create a centralized development platform that would be helpful to third parties took a lot of work. 

The business was rapidly expanding and they were hiring new software engineers simultaneously. Additionally, they had improved significantly at managing infrastructure services like computing, storage, and databases (due to those previously articulated internal requirements). Additionally, out of necessity, they had developed strong skills in managing dependable, scalable economic data centers. They had to be as lean and as effective as they could be as a low-margin company like Amazon. At that point, they began to construct the concept of what AWS would be and wondered if they had a second business offering infrastructure services to developers. That sparked a new conversation about the elements of this operating system and how Amazon could contribute to its development. By the fall of 2003, after further investigation, they concluded that the necessary building blocks for the internet OS were still to be constructed. 

When Amazon Elastic Compute Cloud was introduced in August 2006, AWS became the first to offer a contemporary cloud infrastructure solution. Surprisingly, it took a while for the rivals to respond, and as a result, they currently hold a significant portion of the market. 

How Does AWS Cloud Computing Work? 

Businesses can scale up using the Amazon cloud service without making astronomical initial capital investments. It offers rapid, low-cost access to 69 availability zones (AZ) spread across the globe that offers outstanding IT services. There are connected availability zones with multiple data centers in each of the 22 regions. Users can utilize virtual machines like Amazon AWS EC2 to access a dependable IT infrastructure. 

Businesses can select business-appropriate Cloud Computing models, including Infrastructure as a Service (IaaS), Platform as a Service, and Software as a Service, thanks to Amazon Cloud Computing. The ability to modify the infrastructure capacity of Cloud Computing models to the appropriate size allows the client to adapt to changing market needs.

Types of Service Models in Cloud  

With Cloud Computing, IT departments and developers can concentrate on what matters most while avoiding undifferentiated tasks like purchasing, upkeep, and capacity planning. As Cloud Computing has become increasingly popular, various models and deployment techniques have arisen to fulfill the various needs of users. Depending on your cloud service and deployment strategy, you have varying degrees of control, flexibility, and management.  

Here are some types of service models in Cloud Computing.

  • Infrastructure as a Service – IaaS: Users can instantly deploy processing, storage, and network connectivity. Customers can create their own apps on these resources using this service model. 
  • Platform as a Service – PaaS: It is an acronym. Here, the service provider offers their clients various services, including databases, queues, workflow engines, emails, etc. The consumer can then construct their own applications using these components. The service provider manages the services, resource availability, and data backup, allowing the clients to concentrate more on the functionality of their application. 
  • Software as a Service – SaaS: According to what the name implies, in this scenario, third-party providers offer their clients end-user apps that include certain administrative functionality at the application level, such as the ability to create and manage users. Additionally, customization is feasible, allowing customers to utilize their corporate colors, logos, etc. 

Advantages of AWS Cloud Computing 

The benefits of utilizing AWS Cloud Computing services are as follows: 

  • Thanks to AWS, organizations can use well-known programming languages, operating systems, databases, and architectural frameworks. 
  • With no upfront costs or long-term obligations, it is a cost-effective service that enables you to pay only for the services you really need. 
  • You won’t need to pay for the upkeep and operation of centers. 
  • AWS provides quick deployments. 
  • It’s simple to increase or decrease capacity. 
  • You have instant, unrestricted access to the cloud. 
  • The TCO is relatively low compared to any private or dedicated servers.
