AWS Services Are Delivered On A 'pay-as-you-go' Basis.

Let’s say you want to develop a business process management system. 

In that case you need storage, databases, and servers All of which are customizable depending on your expectations for system functionality and software requirements.

Essentially, this gives you two options. The first is a traditional one: you do the research to define what hardware to purchase, approve the budget, and, finally, buy the equipment. The process usually takes weeks or even months and is quite costly. Not only will you have to make an upfront investment, but you also have to spend money on the proper hardware maintenance.

Alternatively, you can get virtual services in just a few clicks. All you need to do is to choose the instance type that fits your use case, the operating system you prefer and the quantity you require. You’ll get a full, real-time, administrative control over the resources almost instantly. And you can terminate instance (and, as a result, cease paying for it) at any moment once you stop using it.

It seems quite obvious that the latter option has more advantages in terms of business management, budget forecast, and risk mitigation. 
And AWS makes it available to enterprises of any size and from any corner of the world.

Now it’s time to talk about the main advantages in greater detail. Since there are a huge number of cloud computing services AWS provides, the list of benefits is quite long. For this reason, we’ll only focus on those of them which are crucial for the development and running business applications.

Scalability
This is one of the most important benefits you get by opting for AWS. Because, in today’s fast-paced world, a business either grows or “sinks”. That’s why it’s essential that enterprise applications which are vital for your activity could scale as fast and broadly as your business needs it. AWS makes it possible because when you use cloud services, you’re not restricted by the capacity of your physical servers. The opportunities are endless and this means you can develop your business as you envisioned it without thinking about the proper IT infrastructure.

Flexibility
Using AWS requires no long-term commitments from your side. You may adjust cloud IT resources as you require it. Such flexibility creates a great environment for your experiments. Basically, you can try and test whatever you want without too much effort or compromising on quality.

Cost-effectiveness
AWS services are delivered on a “pay-as-you-go” basis. This means that you only need to pay for the cloud IT resources you use. The lower operating costs give you a significant advantage over your competitors. On top of that, you don’t have to make any significant investments in advance so the opting for AWS is completely risk-free.

Security
Security is one of the most critical requirements to any enterprise application. All AWS’ data centers are highly secure, so you don’t have to worry about data leaks and similar issues. You can also increase the level of data protection by adding an additional layer of security and taking advantage of an encryption feature.

Reliability
Whatever enterprise application you want to create, it’s important to make it high-performing and resilient. With AWS, you can build a reliable system that is able to recover from infrastructure failures automatically. But the greatest thing is that with AWS, your coding team can validate recovery strategies by testing the way the system would behave in case of disruptions. This reduces the risk of negative consequences triggered by a system failure.
