Why Learning Only Cloud Services Isn't Enough for Zero-Experience Engineers

Recently, it seems to be a trend in Japan to study cloud services such as AWS and switch to a career in IT without any prior experience. In this article, I will introduce the advantages of public cloud services such as AWS and explain my personal opinion on why it is not enough to just study cloud services when switching to an engineering career with no prior experience.

## What are Cloud Services?
Cloud services refer to the provision of computing resources and other services to users over a network. These services can be categorized as either private or public, and can also be classified based on the type or form of service provided, including IaaS (Infrastructure as a Service), PaaS (Platform as a Service), SaaS (Software as a Service), and more.

## What are the Advantages of Cloud Services?
Cloud services offer cost savings, scalability, and mobility compared to traditional on-premises solutions, where enterprises own physical servers in a data center. Over the years, cloud services have gained popularity in Japan, with many companies migrating their business systems to the cloud, resulting in hybrid or multi-cloud environments becoming more common. Additionally, most new development projects are now cloud-native.

## What is AWS?
Amazon Web Services (AWS) is a public cloud service provided by Amazon and is among the top three providers in terms of global market share. In Japan, AWS's market share has been growing rapidly due to the increasing adoption of cloud services and the platform's advantages in terms of cost-effectiveness, reliability, and flexibility.

## What is a Cloud Engineer?
A Cloud Engineer is a professional who designs, builds, and manages the cloud infrastructure of an organization. This can include public, private, and hybrid cloud environments. Cloud Engineers typically have expertise in areas such as cloud computing, networking, security, and automation.
In recent years, job titles such as Cloud Architect, DevOps Engineer, and SRE Engineer have gained popularity in the field of cloud computing. Although I won't provide a detailed explanation of these roles in this article, those who are interested can easily find more information on them through a simple online search.

## Why is it Not Enough to Learn Only Cloud Services with No Experience?
For those who want to switch to IT with zero experience, it's not enough to just learn Cloud services. While it may seem like learning AWS can lead to a job, it's important to understand that cloud services are just one part of the broader IT field.

Why is it not enough to learn cloud services without any practical experience? There are several reasons why this might be the case:

- Firstly, cloud services are not a complete replacement for traditional on-premises solutions, as there are still physical servers located in the cloud service provider's data center.
- Additionally, cloud services often offer managed services that abstract away many technical details, such as the underlying network infrastructure.
- Without a basic understanding of on-premises solutions, it can be difficult to fully comprehend the underlying working principles of cloud services, even if one learns how to use them.
- On the other hand, mastering one cloud service can make it easier to learn other cloud services, which is why it's important to focus on learning basic knowledge such as networking, security, databases, and programming languages first.

## Learning Suggestions for Those with No Experience
It's important to consider your desired field when deciding what to learn in cloud computing. Don't rush into it simply because there is high demand for cloud practitioners. If you're interested in IT infrastructure, learning cloud services is a good idea, but it's important to have a strong foundation in related fields such as networking or Linux technologies in order to provide room for growth.

Additionally, for non-native speakers of Japanese and English who are interested in working in Japan, language skills in both languages are crucial. Make sure to work on improving your proficiency in these languages.
