Hello! We are a writer team from Definer Inc. In this issue, you are wondering about my recommendations for those who want to change jobs to AWS engineer, and the desirable skills to acquire. Let's take a look at the actual screens and resources to explain in detail.  

This article provides information and practices for those who want to change jobs to AWS engineer, including recommendations for study and desirable skills to acquire, and is helpful for those who want to become an AWS engineer.

In recent years, AWS engineers have been getting more and more attention. One of the reasons for this is undoubtedly the large number of companies using AWS, which is expected to remain strong in the future. The domestic market for public cloud computing itself is also growing at an extremely high rate of more than 10% annually.   To begin with, AWS is the world's top cloud service by market share. Many companies, from startups to large enterprises, are using AWS.   The following advantages are the reasons why companies use AWS. ・Many services are available, and cutting-edge technology can be utilized. ・Reasonable cost and lead time ・There is a lot of information available on the Internet.   The "2025 cliff" issue, which was the subject of a report by the Ministry of Economy, Trade and Industry, is another reason that is driving the use of cloud computing. The 2025 cliff refers to the problem that many companies' business systems will no longer fit into their rapidly changing business models due to aging or black box systems, resulting in economic losses.   Against this backdrop, many are interested in becoming cloud engineers, especially AWS engineers, who hold the top market share.

Becoming an AWS (Amazon Web Services) engineer can open up a range of exciting career opportunities. As an AWS engineer, you would specialize in designing, deploying, and managing applications and infrastructure on the AWS platform. Here are some potential career paths and opportunities in this field:

1. Cloud Solutions Architect: As an AWS engineer, you can work as a cloud solutions architect. In this role, you would design and implement complex cloud solutions using AWS services. You would collaborate with clients and stakeholders to understand their business requirements and create scalable and cost-effective architectures.
2. DevOps Engineer: AWS plays a crucial role in DevOps practices, and as an AWS engineer, you can focus on DevOps automation and infrastructure management. You would work on continuous integration/continuous deployment (CI/CD) pipelines, infrastructure as code (IaC), and tools like AWS CloudFormation and AWS CodePipeline to enable smooth and efficient software development and deployment processes.
3. Systems Administrator/Engineer: AWS offers a wide range of services for infrastructure management, and as an AWS engineer, you can specialize in systems administration and engineering. You would be responsible for setting up and managing virtual servers, networks, storage, and databases on the AWS platform. This role involves ensuring high availability, security, and performance of AWS resources.
4. Big Data Engineer: AWS provides powerful tools for processing and analyzing large-scale data. As an AWS engineer with a focus on big data, you would work with services like Amazon EMR (Elastic MapReduce), AWS Glue, Amazon Redshift, and Amazon Athena to build data pipelines, design data lakes, and implement analytics solutions.
5. Security Engineer: Security is a critical aspect of cloud computing, and AWS offers numerous services for securing applications and data. As an AWS security engineer, you would specialize in designing and implementing robust security architectures, conducting security assessments, managing identity and access controls, and ensuring compliance with relevant standards and regulations.
6. Machine Learning Engineer: AWS provides a rich set of services and frameworks for machine learning and artificial intelligence. As an AWS engineer, you can focus on machine learning engineering, leveraging services like Amazon SageMaker, AWS Glue, and Amazon Rekognition to develop, train, and deploy machine learning models and solutions.
7. Consultant/Technical Evangelist: With extensive knowledge of AWS services and best practices, you can work as a consultant or technical evangelist, helping organizations adopt AWS and optimize their cloud infrastructure. This role involves providing guidance, conducting assessments, and delivering training and workshops to assist clients in leveraging AWS effectively.

To become an AWS engineer, you should have the following:   <Must> Basic knowledge of IT infrastructure Basic knowledge of networks, servers, databases, etc. is necessary regardless of cloud/on-pre. First, it is recommended to read textbooks such as Basic Information Technology Engineer to understand the overall picture and overview, which will make subsequent studies easier. In addition, using a public cloud such as AWS and building your own Linux servers and databases will deepen your understanding.   <Must> Knowledge of AWS It is necessary to understand basic AWS services such as EC2, S3, and RDS. The best way to acquire knowledge is to create your own AWS account and try building your own VPC, EC2, and RDS. If you can afford it, you may also want to take the AWS Certified Solution Architect Associate certification.   <Nice to Have> Container knowledge From this point on, it is nice to have knowledge of containers. More and more companies are adopting containers these days. You should know basic Docker commands and how to write Dockerfile.   <Nice to Have> Knowledge of Infrastructure as Code Knowledge of Infrastructure as Code (IaC) is also useful. Infrastructure as Code is a concept of managing IT infrastructure resources with code. You will be able to understand and grasp the key points of Infrastructure as Code by using Terraform and AWS Cloud formation to build AWS architecture.   AWS certifications validate your expertise and can enhance your credibility as an AWS engineer. Choose the certifications that align with your career goals and expertise level.   The AWS platform and its services are constantly evolving. Stay abreast of the latest developments, new services, and best practices by regularly exploring AWS documentation, attending webinars and conferences, and participating in online forums and communities. Continuous learning is crucial to maintain your skills as an AWS engineer.   Keep these in mind and become a good-looking AWS engineer!
