 When you ask people who have been using or are using Amazon Web Services, they are kind of tongue tied and they cannot give you very correct, straight, right answers why they have been using Amazon Web Services and why they are maybe recommending Amazon Web Services to other developers. So in this module, I will list five of those reasons why developers use Amazon Web Services and in the next module, I will talk about the next five reasons why developers use Amazon Web Services. So let's dig into it and let's look at the details. So these are the first five, not in any particular order, the reasons why Amazon Web Services are used. And now we will go into more detail into each of them one by one provides it agility. Agility means the ability to react quickly, okay, to act fast. So it agility means that the IT department in your business is reactive. It goes ahead. It goes along, along with the changes, along with how the business is proceeding. How the business would like to move ahead. But that is not the case historically and traditionally. Why because historically, IT department has developed number of processes, number of procedures, which have to be stitched together, which have to be tied together. There are many things which need to be addressed. Therefore, people sometimes call the IT department as the department of no, they are good at saying no, okay, why because these are multi departmental, okay, manual time consuming serial processes until this is done, this cannot be done. And since this cannot be done, this cannot be done. And there are multiple such processes across multiple departments. So that results into a lack of IT agility. That is not the case for Amazon Web Services, because it offers integrated and automated services, which does not involve humans, not neither in the monitoring of the services humans are involved, nor into taking the actions humans are involved, right. And as a consequence, the systems are designed in such a manner that it provides parallelization of the services. And when the parallelization is there, then the response is quick. It takes less time. So Amazon Web Services users, they respond quickly, they respond quickly to the demands of the business. And the IT department is no longer the department of no. It is no longer the department of no. Why? Because of the Amazon Web Services. So that is one reason, IT agility, business agility, now businesses have to respond and act and move quickly as per the changes in the environment, as per the global changes also. Now, if the business is required to move like this, and the IT department is unable to move with the business, that can be dangerous for the business. That can be something which the business should be concerned, so that is a problem. The reason being that historically as you can see on the screen, historically the IT departments have what they have done, they have automated different processes in an organization. They developed the billing system, they developed the inventory system, the financial system, the HR system, many systems, okay. So the things were done through those systems historically. But the today's user, they want self-service. Today's user want to be in control of the services, of the products which the company makes available. And that user requires access to those services and products through a handheld device. It could be a mobile phone, it could be a tablet, okay, or and of course they are using, they want to access through the websites also, right. So businesses need to roll out new applications quickly, because if one business is not agile and not providing those services and other businesses offering, the customers will shift. So some departments call Amazon services as a rogue or the shadow IT, rich services ecosystem as a traditional application building is time consuming. It takes a lot of time, not only it takes a lot of time, but it is prone to errors, mills, calculations, testing, skips and so on. But when you have the software as a service, with Amazon web services, then you don't have to do all of those things. And the range of services is part of Amazon web services. And since all those services, they are available at a central location, and the communication takes place among those services at a central location that results in low latency. And when the latency is low, the response time decreases and quick response is received. Okay. And then of course, there are homegrown third party developers and services, which have developed the services augmenting the Amazon web services accordingly. And of course, they have a similar pricing model also. Amazon web services simplifies the IT operations. And when the IT department subscribes to the Amazon web services, it tremendously reduces the burden on the IT department. And the IT department burden systems shrinks. The administrative work shrinks. As a result, more budget can be devoted to differentiating the company vis-a-vis other companies, other businesses. That is the benefit of using the Amazon web services. And of course, Amazon web services spans the globe. Okay. There are the location benefits, lower network latency, better performance, and so on. So Amazon web services is organized into regions. Okay. And the regions are throughout the world. The United States, the Europe, okay, United States, the Europe. And you can see Australia also, number of Asia has two regions because Amazon web services is a global service. Users can take advantage of services located nearby, okay, nearby located services, which is led into network lower network latency. The global nature of Amazon services also leads to local services ecosystem in the form of native consultancies. Local ecosystem, native consultancy, okay, native consultancy and system integrators, making it easy for users to obtain help delivered in native language, okay. In native language, little language, and with local expertise, Amazon continues to roll out new global locations and new services associated with them. And these are the first five reasons why Amazon web services are adopted. That is all for this module. Thank you very much.
