What is Amazon Web Services?

What is Amazon Web Services? A Comprehensive Guide To Cloud Computing.

Amazon Web Services, also known as AWS, is one of the leading cloud service providers that supply a range of cloud services, making cloud technology accessible to individuals and enterprises across the globe.

Amazon provides services like managing and maintaining hardware and infrastructure, which helps individuals and enterprises save the expenses and expertise required to host these services on site. These services are usually accessible to users via the internet on a free or pay-per-use basis. 

Amazon tried launching Merchant.com, an e-commerce service platform designed to help businesses like Target and Walmart in the earliest days. Any third party business under the sun, create their ecommerce platform on top of the Amazon engines. An idea great in theory, this concept failed wonderfully in practice. Amazon found itself grappling with a ton of startup debt and delivery issues.

The planned implementation of the ideas in three months took three months in its pre-setup phase due to unexpected technical issues. Only when the company’s then-chief of staff, Jeff Bezos, took it upon himself to find the root cause did they find that their bottleneck lay in the team’s styles of independent working. The work of Amazon was split into various smaller teams, all of which required storage, compute and databases.

These were being built and used by every single team separately for every single project, leaving Amazon to start from scratch for every new project every single time. The internal teams realized that they would reduce their downtime by a considerable amount of time if they just shared a few resources and accessed them through a shared server.

They also, in turn, discovered that this gave each employee a lot more time since they were all doing the same work in their separate team. Lastly, they discovered a faster way of working since they did not have to start from ground 0 with every new project. Now when you discover so many good things from a tiny idea, you do not just keep it to yourself!

Amazon realized their idea was so good that some people would pay for it. That is how they launched Amazon Web Services, offering upto three cloud services back in 2006. Cut to 2021, and they now offer a little over 200 fully-featured cloud services powered by data centers present in over 190 countries. They are in every corner of the world, leaving their now CEO Jeff Bezos as the richest man out on the planet!

What exactly does AWS offer?

Amazon Web Services offers over 200 fully functional cloud-based products. These include computing, storage, databases, networking, developer tools, management tools, IoT, security, and enterprise management tools. These services apply to everyone from startups to full-scale large enterprises. AWS helps deliver these services globally and enables companies to work faster, reduce their IT costs, and scale with ease. Ranked as one of Gartner’s leaders in the 2021 Magic Quadrant for Cloud Infrastructure, AWS is credited for offering standardized, highly automated services that can be integrated with ease. 

AWS provides a range of services within each category, making it easy for organizations of every kind to find a service suitable to their needs. For example, within Analytics, their Amazon FinSpace provides you with all the essential information needed for a finance company. In contrast, Amazon RedShift is all about data from warehousing units. Similarly, under everything from storage to developer tools, you can find business-specific and size-specific use cases to match your needs. 

So how did Amazon become one of the biggest companies out there? What makes Amazon Web Services so highly successful?

However, hold on, how successful is Amazon Web Services? Does Amazon Web Services offer much scope for developers? What are the pros and cons for businesses when they choose to work with Amazon Web Services? What is differentiating Amazon from Google, Microsoft, or any other cloud provider out there?

That is a list full of questions, and we suggest finding a comfy chair and maybe a cup of coffee because we plan on answering all of them in this guide, so keep reading!

Amazon Web Services VS Google Cloud Platform Vs. Microsoft Azure


While there are one too many cloud providers in the market, to try and count for the race for the top has been reserved for three industry sharks, Amazon, Google, and Microsoft. The whole world is moving onto the trend of using cloud services, and it is the way to go with the internet. The question is no longer why you should use the cloud but rather more of who should you choose when picking a cloud service provider?

While there are a bunch to pick from in this section right here, we will focus on all the offerings that differentiate the big 3: Amazon, Google, and Microsoft, to help you conclude which one is better for YOU!

Now when speaking of what sets them apart, there is a bunch of things to consider because, on the face of it, all three are great cloud service providers, in a highly competitive rivalry with each other, which means that as a customer, you are guaranteed to get almost all of the mainstream cloud services and be satisfied with their quality from either of the providers regardless of whom you choose. 

Comparison at a glance:

Amazon: AWS is the leading cloud service provider. They were the first to market and enjoyed staying in the market without any competition, allowing it to establish its market share for quite some time before Microsoft and Google came around. Amazon is great, but its primary focus is on the public cloud, meaning that interoperability is not the top priority at an Amazon data center if you are a private or hybrid cloud enterprise. Their cost structure can also be a little confusing for businesses to understand fully. 

What kind of services would you find at Amazon Web Services?

AWS: Amazon offers a range of cloud services, and they are adding to this list quite frequently. However, when you sign up for AWS, you are signing up for:

  • Developer, engagement, and management tools
  • Database and storage solutions
  • Business productivity tools
  • App integrations
  • Compute 
  • Machine learning and predictive analysis

Google Cloud: While Google was the last to enter the cloud market, they are a very well-funded enterprise in the competition. Compared to the other two, it does not focus on enterprise, but it more than makes up for its tech expertise where it lacks in this. Google is an industry leader when it comes to deep learning, artificial intelligence, and machine learning.

What kind of services would you find with Google Cloud Platform?

GCP offers relative ease of use and setup, making it easy for newcomers looking for cloud services. With GCP, you can find:

  • App development
  • SMB business analytics and AI
  • Productivity and workload management tools
  • Data management and storage

Microsoft Azure: A very close competitor to Amazon, Microsoft is the runner-up leading cloud service provider in the market. With its years of experience working to help build professional tools to accelerate businesses, you might say Microsoft has an inside window into figuring out the needs of an enterprise. It completely understands the functionality of businesses and focuses heavily on providing seamless interoperability to businesses that are still keeping their roots attached with their private data centers. 

What are some services offered by Microsoft Azure? 

Here is a bunch of services that Microsoft Azure offers:

  • Game and app development
  • Scalable data warehousing
  • DevOps
  • Blockchain technology
  • Big data and predictive analytics
  • IoT

Here is a table that gives you an overview of the key differences between the three platforms:
