What Is Amazon Web Services, and Why Is It So Successful?

Amazon Web Services (AWS), the cloud platform offered by Amazon.com Inc. (AMZN), has become a giant component of the ecommerce giant’s business portfolio.

In the first quarter of 2024, AWS brought in $25 billion in net sales. Having grown steadily, AWS is a frontrunner to other cloud computing platforms such as competitor Microsoft Azure.

So what is AWS, and why is it so lucrative and successful for Amazon?

Key Takeaways

• As the lead cloud computing platform, Amazon Web Services (AWS) is the primary profit driver for Amazon.
• AWS provides servers, storage, networking, remote computing, email, mobile development, and security.
• Amazon controls more than a third of the cloud market, almost twice its next closest competitor.

What Is AWS?

AWS is made up of many different cloud computing products and services. The highly profitable division of Amazon provides servers, storage, networking, remote computing, email, mobile development, and security. AWS can be broken into three main products: EC2, Amazon’s virtual machine service; Glacier, a low-cost cloud storage service; and S3, Amazon’s storage system.

AWS is so large and present in the computing world that it has far outpaced its competitors. As of the first quarter of 2024, one independent analyst reports AWS has over a third of the market at 31%, with Azure following behind at 25%, and Google Cloud at 11%.

AWS has 105 availability zones in which its servers are located. These serviced regions are divided not only to allow users to set geographical limits on their services (if they so choose), but also to provide security by diversifying the physical locations in which data is held. Overall, AWS spans 245 countries and territories.

Cost Savings

Amazon founder Jeff Bezos has likened Amazon Web Services to the utility companies of the early 1900s. One hundred years ago, a factory needing electricity would build its own power plant but, once the factories were able to buy electricity from a public utility, the need for pricey private electric plants subsided. AWS is trying to move companies away from physical computing technology and onto the cloud.

Traditionally, companies looking for large amounts of storage would need to physically build a storage space and maintain it. Storing on a cloud could mean signing a pricey contract for a large amount of storage space that the company could “grow into.” Building or buying too little storage could be disastrous if the business took off and expensive if it didn’t.

The same applies to computing power. Companies that experience surge traffic would traditionally end up buying loads of power to sustain their business during peak times. On off-peak times—May for tax accountants, for example—computing power lays unused but still costs the firm money.

With AWS, companies pay for what they use. There’s no upfront cost to build a storage system and no need to estimate usage. AWS customers use what they need, and their costs are scaled automatically and accordingly.

Scalable and Adaptable

Since AWS’s cost is modified based on customers’ usage, startups and small businesses can see the obvious benefits of using Amazon for their computing needs. In fact, AWS is great for building a business from the bottom as it provides all the tools necessary for companies to start up with the cloud. For existing companies, Amazon provides low-cost migration services so that your existing infrastructure can be seamlessly moved over to AWS.

As a company grows, AWS provides resources to aid in expansion. As the business model allows for flexible usage, customers will never need to spend time thinking about whether or not they need to reexamine their computing usage. In fact, aside from budgetary reasons, companies could realistically “set and forget” all their computing needs.

Security and Reliability

Arguably, Amazon Web Services is much more secure than a company hosting its own website or storage. AWS currently has dozens of data centers around the globe that are continuously monitored and strictly maintained.

The diversification of the data centers ensures that a disaster striking one region doesn’t cause permanent data loss worldwide. Imagine if Netflix were to have all of its personnel files, content, and backed-up data centralized on-site on the eve of a hurricane. Chaos would ensue.

In fact, localizing data in an easily identifiable location and where hundreds of people can realistically obtain access is unwise. AWS has tried to keep its data centers as hidden as possible, locating them in out-of-the-way locations and allowing access only on an essential basis.

The data centers and all the data contained therein are safe from intrusions, and, with Amazon’s experience in cloud services, outages and potential attacks can be quickly identified and easily remedied, 24 hours a day. The same can’t be said for a small company whose computing is handled by a single information technology specialist working out of a large office. 

Criticism of AWS

While the success of AWS is unquestionable, critics of the service say Amazon is abusing its control of the market share by engaging in anticompetitive behavior. This criticism has come from open-source database makers that claim Amazon is copying and integrating software that was originally created by other tech companies.

One such company, Elastic, sued Amazon for allegedly violating trademark laws. A statement released by the company claimed that “Amazon’s behavior is inconsistent with the norms and values that are especially important in the open-source ecosystem.” The lawsuit was settled in February 2022.

How Does AWS Do It for Less?

The Bottom Line

Amazon Web Services is a cash cow for Amazon. The services are shaking up the computing world in the same way that Amazon is changing America’s retail space. By pricing its cloud products extremely cheaply, Amazon can provide affordable and scalable services to everyone from the newest startup to a Fortune 500 company.
