1. Benefits of moving to AWS
-
a) Cost: Initial costs and price reductions
AWS has no initial costs. We have a pay-as-you-go system where you pay only for what you use. For example, if you buy a server on-premises, you pay for the server at the time of purchase, so you're wasting money if something unplanned happens and you don't use that server. With AWS, you don't have to pay for things you don't use because you won't be charged for them once you stop using them. And since all the fees are published on the AWS site, there is no need to inquire or apply without knowing the fees.
In addition to the initial cost, AWS also offers regular price reductions.

b) System operation: Reducing the burden
If you set up your own system, you must always anticipate the increase in the number of users and secure IT resources such as servers. For example, if you have more users accessing your system and you don't add more servers, your system will go down. It is possible to increase the number of servers by buying more servers, but it takes time and you have to continue to maintain and manage them even if you no longer need them.
With AWS, you can increase or decrease the number of servers in a few clicks and a few minutes. You can also change the size of the server you are currently using, so you can change the specs of the server that is running during the day and night, for example.

c) Availability of latest technology
There are over 165 services available in AWS. This includes a number of services that make use of current technologies such as IoT and Machine Learning. Version upgrades are also frequent, with over 1430 upgrades in 2017.
More than 90% of these upgrades are based on requests from AWS users. It can be said that the upgrade is really necessary to meet the needs of the users.
The advantage of having a wide range of services is that you don't have to combine them with other companies' products.
The more products from other companies are combined, the more complicated the maintenance and operation of the system becomes and the more meetings are required. When a failure occurs, it takes a long time to pursue the cause and formulate a response plan. If you can develop and maintain your system using only AWS services, you can make inquiries in one place. In return, users can spend their time on their own business.

d) Benefits of moving from on-premises to AWS
On-premise means that the company prepares its own servers and other facilities and does everything from application development to infrastructure management and operation by itself.
What are the benefits of moving from on-premises to AWS, a cloud service? There are four major advantages to this.
i) Overwhelmingly shortens the time it takes to use
On-premise, it can take 1-2 months to set up the IT infrastructure when developing a new application, but with AWS, all you have to do is sign up and go through the process over the Internet so you can start using it right away. It's easy to navigate and just click on the resources you need online.ii) Use of resources to keep pace with shrinking/expanding demand
As a cloud service, AWS allows you to stop using applications as soon as they run out of demand. You can always stop you when you're not using it, and there is no need to continuing to pay the fees. In the case of on-premises, even if an application is no longer in use, it may not be able to be stop immediately, and the IT infrastructure needs to be processed, which is very expensive.iii) Pay-as-you-go system, where you pay only for what you use
Pay-as-you-go is a pricing model in which you pay only for what you use.
In addition, depending on the content of the service you are using, AWS has a system that allows cheaper prices when users use them wisely, such as reserve instances that can be discounted by reserving them for one to three years in advance, and spot instances that are priced based on bids.iv) Conversion of IT assets from fixed to variable costs
Whereas on-premises typically involves buying equipment as an initial IT investment and amortizing it as a fixed cost, the cloud can improve profit margins by turning fixed costs into variable costs that match demand.

2. Case study
Here are some examples of how and what companies are using AWS.
-
a) Daikin Industries, Ltd.
Daikin Industries, Ltd., a provider of air conditioning equipment, has built a new cloud system, the Global Platform, with a serverless architecture to meet the increasing number of connected air conditioners. It has taken on the challenge of creating a system that can guarantee connectivity to 10 million units, using managed services such as AWS IoT, AWS Lambda, and Amazon Kinesis to reduce initial and operational costs, and to motivate development teams by increasing their exposure to the latest technologies.
-
b) Daiso Sangyo Co.
The company is known for the 100-yen store "Daiso". Here's a look at how AWS is being used.
Daiso changed its infrastructure environment from on-premises to the cloud, adopting AWS in 2013 and building an automated ordering system using Amazon Redshift in 2014. It also built a portion of product management system with AWS Lambda, followed by a serverless implementation of a centralized data processing system for our global stores.By reducing the infrastructure management of POS data, which is increasing year by year, the company has succeeded in reducing management effort by about 90% and application implementation effort by about 20%.

3. Conclusion
We have introduced the benefits of moving to AWS. By moving from on-premises to cloud services, many companies have been successful in reducing costs and adopting the latest technology. With a long history of cloud services and a proven track record, why not consider moving to AWS?
