AWS Certified Developer Associate certification is for the individuals who are looking for developer role and have years of experience in the development and maintenance of AWS applications.
The certification validates the ability of the developer in:
- Understanding of AWS core services, its uses and best practices deployed in basic AWS architecture.
- Demonstrating the proficiency of the developer in development, debugging and deploying the AWS based applications.
The AWS certified developer Associate certification is becoming very popular amongst the professionals working with Amazon Web Services (AWS). The AWS CDA -2019 exam has become harder than before as it now covers a number of new AWS services and skills.
With the rising popularity of the cloud-based applications, the companies are shifting their workloads to the cloud, and cloud computing has been amongst the core competencies of every enterprise. With this shift, the companies require developers with a new set of skills to design, develop and maintain the applications on the cloud.
As the most established and the leading cloud computing services Provider Company, the Amazon Web Services is considered as the thought leader and point of reference for the competitors of the industry. With over a million customers, Amazon Web Services is the most popular choice of cloud adoption.
Here are four new skills to be mastered for the AWS certified cloud practitioner.
Great emphasis is given to the Elastic Beanstalk and the focus of the AWS Certified Developer Associate 2019is mainly on this topic.
AWS Elastic Beanstalk is a cloud deployment and provisioning service that automates the deploying applications on the AWS infrastructure. The elastic beanstalk handles all the deployment information automatically. It is not only cost-effective but is also scalable and reliable. The service can be extended to multiple development stacks. It is easy to use, flexible, and also has built-in notifications and monitoring. Moreover, troubleshooting options are easy.
It supports all the platforms such as .NET, Node.js, Java, Ruby Stack etc. The editing and the creation of the application can be done using any IDE or editor to package your deploy code. You can also use the Elastic load balancer or it can be managed automatically.
It supports rollback as well as the automated version deployment features. For instance, if you are deploying an application in Elastic Beanstalk, it spreads the total load on the multiple servers, so that the traffics spreads evenly and reduces the risk. Once the production is moved, you can switch back to the previous version easily. There are not only one but five different rollout strategies you can use.
Just like its name says Amazon X-rays helps the users to get the information about the errors in the micro-service architecture. It is one of the best tools to use which helps all the developers to debug the production.
To know the root cause of the application and to troubleshoot the issues and errors fast and easily, Amazon X-ray is very much helpful. As you go through the developed application, you can see the end-to-end view of the requests it gets. Moreover, it even shows a full map of the underlying components of your application. Hence, X-ray can be used in both ways. It can be used in development as well as can be used in production. It can be helpful for the micro service architecture app which consists of more than a thousand services.
To discover all the issues in the application, AWS X-ray can trace the feature, allows you to follow request path to the pinpoint the main issue. Moreover, you can also use it to improve the performance of the app. Above all, it can easily be integrated with all the Amazon web services such as Amazon EC2 Container Service (Amazon ECS), AWS Lambda, Amazon EC2, and AWS Elastic Beanstalk.
This is one of the best technologies for developers and it is also a new and very dominating topic for the exam and hence an AWS certified cloud practitioner should know this skill.
You can build as well as run any type of application without keeping the servers in mind. Serverless is the whole new native architecture in which all the operational services are managed by the cloud. In other words, you don’t need to worry about the server about the provisioning, operating system maintenance as well as patching and capacity provisioning. All you have to do is build the application and you will be provided with everything you need to run as well as scale your application.
There are many reasons why you should master the serverless skill, the main benefit is the automation. You don’t need to manage all the servers. Also, there isn’t any software you have to install or maintain. You can adjust and scale by just changing the units of consumption, you don’t need to toggle units of each and every server.
Along with this, the scaling of serverless is very flexible and can be done hassle free. Moreover, you only pay for what you use. Hence, it is one of the most cost-effective ways to quickly manage your application.
Focus on Developer tools
If you are planning to master the AWS certification exam, you need to know about the new developer tool which is very much helpful to support the Continuous integration or Continuous delivery technology. CodeBuild, CodePipeline, CodeDeploy, and CodeCommit are some of the AWS services are its part. It can handle all the pipelines of CI/CD without having to manage a server.
Basically, AWS Developer tools are just a set of many services by which developers and all the other IT professionals can practice DevOps easily as well as deliver the software safely. You can securely store the source code and version control for your application’s code along with the automatically build, test, and deploy of the uploaded application to AWS.
There are several main tools you need to know to master the Exam to be an AWS certified cloud practitioner. By this, you will know the basics of the developer tools
- AWS Cloud is an IDE for writing and debugging the code.
- AWS CodeStar helps you to develop and deploy the application
- AWS X-ray helps you in analyzing the production apps.
- AWS CodeCommit stores you code in private Git repositories
- AWS CodePipline is used for CI/CD
- AWS CodeBuild is for building and testing the code
- AWS CodeDeploy is used to automate the code deployment.
It is essential for the cloud IT professionals who are planning to take the AWS Certified Developer Associate 2019 exam to speed up and master these new skills, concepts and developer tools to mater the AWS certification.
