Also, we have the Cloud formation templates where with the click of a button you can roll out multiple environments.
- Services it Offers: AWS offers Elastic Computer Cloud (EC2), Simple Storage Services (Amazon S3), and other solutions. Later on, in 2009, more services like Content Delivery Network (CDN), Amazon Cloud Front, and Elastic Block Store (EBS) came into existence.
- Low-Cost: AWS is the friendliest vendor as it offers you a pay-as-you-go service and also allows you to bid for the cost. Also, it gives you the benefit to lower your charges as your service agreement increases.
- Security and Flexibility: The most important feature any cloud service provider can provide is security hence, AWS takes care of your data using IAM (Identity and Access Management). Another term is flexibility, wherein it gives you the freedom to use the service as per your requirement.
Roles and Responsibilities of an AWS Engineer:
- Responsible for the planning, implementation, and growth of the AWS cloud infrastructure.
- Should be familiar with the term CI/CD (Continuous Integration/Continuous Delivery, and tools like AWS Code Deploy, AWS Code Build, and AWS Code Pipeline.
- Knowledge of automation and troubleshooting.
- Experience with DevOps tools like Docker, Kubernetes, Ansible, GitHub, Jenkins, Maven, and Arti-factory.
- The idea of writing Infrastructure-as-Code (IaC), using tools like Terraform.
- Experience in using monitoring solutions like ELK STACK, Prometheus, and Cloud Watch.
- Knowledge of programming languages (XML data, R math, Erlang functional, Python procedural, and Go).
- Have a good grasp of EC2, ELB, RDS, and S3.
How to Become an AWS Engineer?
There are various technical terms you should have a good grip on and steps you have to follow if you want to become an AWS Engineer:
Step I
A. Basics of Linux OS
You should have an idea of what is an Operating System and how OS works. Having knowledge of Operating Systems lets you know how your system manages hardware and software resources. It acts as an interface between the user and the hardware.
Specifically, Linux Operating System is the one you must have a good grip on.
B. Programming Languages
Programming Language is the basic fundamental concept you must know. Having command over anyone’s programming language is a benefit if you’re to enter into the world of the cloud. Out of all programming languages, Python and Go are the most required.

C. Orchestration
Cloud Orchestration can be defined as the coordination, arrangement, or end-to-end automation of the deployment of services in the cloud environment. AWS provides you with an orchestration solution to provision resources in a consistent manner so as to scale your business. To read more about this, refer to the article – Orchestration in Cloud Computing.
Step III
A. DevOps and Containerization
DevOps is a combination of software development and IT operations. It provides continuous delivery of applications at high velocity. Also, it takes care of the system development lifecycle. There are some points you must take care of
A containerization is a virtualization form where applications run in isolated places while using the same shared operating system. It is a portable and fully packaged computing environment.
B. Kubernetes
Kubernetes, written in Go-Lang, and developed by Google is an open-source container management tool with where automation of container scaling and deployment, and container load balancing. Be it public, hybrid, or on-premises, it works well with all cloud vendors.
C. Virtualization
Virtualization which began in the 1960s is the creation of a virtual version of a server or a desktop. It is the foundation of cloud computing that allows the efficient utilization of physical computer hardware. The machine in which virtualization is performed is called a virtual machine that runs its own operating systems. To read more about this, refer to the article – Virtualization and its Types.
Step IV
A. Cybersecurity
Cybersecurity is the practice of protecting electronic devices and data from attacks. It began in 1972 with the aim of assuring the safety of sensitive data like credit card details, addresses, passwords, etc. It is used by the government, hospitals, the military, corporate organizations, and finance.
B. Security and API
With AWS, you should have the confidence that your data is secure with the most flexible and secure cloud computing environment. It allows you to automate manual security tasks to accelerate scaling business. To know more about this, refer to the article – Security Model of AWS Cloud.
API (Application Programming Interface) acts as an interface for communication between two applications. It helps developers to create, publish, maintain, monitor, and secure APIs at any scale. API Gateway manages all the tasks such as CORS support, authorization, traffic management, monitoring, and API version management. In AWS, you pay for API calls you get and the transferred amount of data. Must refer to the article – Amazon Web Service – Introduction to API Gateway.
Step V
A. Cloud Computing Service Model (IaaS, PaaS, and SaaS)
Cloud Computing Service Models are the models created to provide access to the resources and services to the users. It offers a pay-as-you-go service. There are three service models-
- Infrastructure as a Service (IaaS) – Infrastructure as a service offers you storage and networking resources on demand. Also, known as “Hardware as a Service”.
- Platform as a Service (PaaS) – Platform as a Service is a service provided to the users for complete development and deployment in the cloud. Developers get access to free hardware and software with low pay.
- Software as a Service (SaaS) – SaaS is a service where software is given to users with the help of the internet. You don’t need to install the software in your local system instead get access to it on your system virtually.
You will get to know the importance of each service model, once you read the Difference between IAAS, PAAS, and SAAS.
