AWS Developer Skills

If you aspire to become an AWS Developer, you must know what essential skills to be acquired. The following section highlights AWS Developer skills that organizations are looking for:


One of the most essential skills an AWS Developer must know is how to deploy web applications to AWS. Various methods for AWS deployment already exist and new ones are released quickly. Owing to the continuous evolution of the various strategies of deployment, an AWS Developer must stay up-to-date with the latest strategies.

An AWS Developer must be familiar with how to manually deploy a web application to an EC2 server. He/she must be acquainted with Cloud Formation and comprehend how to apply it not just for deploying an application but also to set up your app's infrastructure.

With the increasing popularity of containers, AWS developers should be skilled at how to deploy applications through Elastic Kubernetes Service (EKS) for Kubernetes or Elastic Container Service (ECS) for Docker.


The knowledge of AWS software development kit (SDK) streamlines working with AWS. So, this one is another vital skill that an AWS Developer must possess. AWS SDK allows an application to interrelate with AWS in the code. Note that the API layer is so huge in SDK that even experts stay stuck in finding new ways that can accomplish it.

Many AWS Developers may not know where to start when retrieving an object from an S3 bucket or connecting to a DynamoDB table. Therefore, if you are familiar with AWS SDK then you would stand out from the crowd and earn better admiration in the organization.

AWS Database

Databases can be used in varied ways in web applications. For the same, AWS helps. But it is important to identify which database service is pertinent for a specific application. Hence, if an AWS Developer is not thoroughly acquainted with all available options, there are high chances of opting for the incorrect option and it could obstruct the growth of the application.

You can go through the existing options in RDS. Keep in mind that Aurora constantly improves and incorporates new layers of compatibility with PostgreSQL and MySQL. On the other hand, DynamoDB persists to be a famous choice for easy and quick NoSQL database needs. Since it is a REST-based API, no long database connection is required. DocumentDB is known to be the latest type on the AWS database arena and it provides MongoDB compatibility. In case DynamoDB couldn’t work for your document database requisites then DocumentDB may work. So, an AWS Developer must be familiar with DocumentDB.


An AWS Developers must be aware of all the aspects of the AWS security model as well as IAM. Frequently, AWS Developers misinterpret IAM. So, this leads to issues and bugs. An AWS Developer is tasked to enhance the AWS work process and the same can be achieved by understanding how policies and roles work.

In many Cloud-based organizations, security management is one of the complicated services which demand proper understanding. AWS has launched it to ascertain that management and retrieval of secrets like API keys, passwords, etc., in web applications becomes less complex. So, an AWS Developer must be skilled at how to manage and access security components like passwords, API keys, etc.


Dealing with roadblocks becomes easier if you are experienced at how to solve them. The same holds true for AWS, so if you know debugging then you can easily overcome any issue in AWS. It is important to note that debugging doesn’t come with an exact roadmap. The only approach to learn it is by mastering AWS.  The majority of times, the issues take place because of VPC bases access rules or IAM permissions. But working on the platform to encounter these issues is a recommended approach.

Serverless services

In recent times, for AWS developers, API Gateway and AWS Lambda prove to be excellent solutions. All AWS developers should comprehend the usage of such serverless services. If they are proficient in this aspect then they can stand out from others because even experienced professionals don’t understand it.

The process of building applications across serverless architecture is streamlined with the use of AWS SDK and Cloud Formation. The implementation of an open-source serverless framework allows AWS Developers to implement simple configuration files to build up efficient serverless technologies.

AWS developer tools

These tools assist AWS Developers in securely developing, testing, storing, and deploying software. In other words, these tools are a set of services that facilitate IT developers and AWS Developers to safely and quickly deliver software. Names of some of the popular AWS Developer tools are AWS Cloud Development Kit, AWS CloudShell, AWS Cloud9, AWS CLI, etc.

Programming language know-how

One of the most significant AWS Developer skills is the knowledge of coding. Programming languages like C#, PHP, Java, ASP.Net, and Python.

Expertise in API and Web Service

The need for using web services, API, and cloud architecture arises when you want to integrate applications on the internet. Consequently, one of the most desired skills for an AWS Developer is an in-depth understanding of API and Web Service including WSDL, XML, and more. They are useful for service listing and data transfer. After you become proficient in these technologies, the next step is to appear for Cloud certification exams that can land a decent-paying job role.

The choice of a storage solution

Cloud storage relates to the storage of data on the Internet. Cloud storage offers ample benefits like security, data backup, deployment, accessibility, and more. Other forms of Cloud storage are private, public, personal, and hybrid. AWS Developers need to know which storage to choose depending on the needs of the company and its size. Moreover, they must know how and where to store data. Knowledge of how Cloud storage functions is great.

Here is the list of some common skills that every AWS Developer must own:

  • A decent understanding of Linux/Unix administration
