  • Before embarking on a CloudStorming activity, the cloud engineer would convene all essential stakeholders and discuss the exercise’s aims.
  • Elastic Beanstalk, in particular, is an important service for deploying, managing, and scaling applications.
  • Such systems are designed to protect any current working system when various failures occur during any specific time.
  • Git is the most popular version control system and is the industry standard, so it’s important to show the interviewer that you’re familiar with the system and comfortable using it.
  • AWS Direct Connect is a network service that provides an alternative to using the Internet to access AWS cloud services.
  • Security groups – serve as a firewall for EC2 instances, allowing you to regulate inbound and outgoing traffic at the instance level.
  • Interviewers ask this question to gauge your familiarity with AWS services and assess your ability to determine when and where to use them effectively, which is essential for a successful AWS Engineer.
  • When an event like this occurs, the “automatic rollback on error” feature is enabled, which causes all the AWS resources which were created successfully till the point where the error occurred to be deleted.

To protect communication within the VPC, encryption technologies such as IPSec and SSL can be used. Managing and supplying infrastructure using code rather than human setup is called infrastructure as code (IaC). IaC is connected to CI/CD since it allows infrastructure changes to be tested and deployed automatically using the same pipeline as code changes, boosting the speed and reliability of infrastructure upgrades. Utilizing a cloud-based database solution offers numerous benefits, but also comes with several drawbacks that should be considered.

#1: What are the key benefits of GCP versus other cloud providers?

The interviewer wants to assess your understanding of cloud migration strategies and your ability to handle the complexities of moving an application from an on-premises environment to AWS. I leverage AWS Identity and Access Management (IAM) to create policies and roles with the principle of least privilege, ensuring users and applications have only the necessary permissions to perform their tasks. Additionally, I employ tools such as AWS Organizations and Service Control Policies (SCPs) to manage account-level restrictions and maintain a clear separation of duties. The hiring manager is seeking to gauge your understanding of AWS architecture and its various components. As an AWS Engineer, you will be working with these components daily to design, implement, and manage cloud infrastructure solutions.

You can also discuss your experience with monitoring tools like AWS CloudWatch or Splunk to detect any suspicious activity on the server. Finally, explain how you would stay up-to-date on the latest best practices for data security in the cloud. Identity and access management (IAM) solutions such as AWS IAM, Azure AD, and Google Cloud IAM can handle access control and authentication for cloud-based services. These solutions provide numerous features to ensure the safety and security of your cloud data, thereby helping to implement security and regulatory compliance.

When should you use the classic load balancer and the application load balancer?

When a metric threshold is crossed, the Auto Scaling group adjusts the number of instances accordingly, either launching new ones or terminating existing ones. I started by integrating our code repository with CodePipeline, which allowed us to automatically trigger the build process whenever new code was pushed or merged into the main https://remotemode.net/ branch. Next, I configured CodeBuild to compile the application, run unit tests, and package the artifacts. Once the configuration file is complete, I run ‘terraform init’ to initialize the backend and download necessary provider plugins. If everything looks good, I run ‘terraform apply’ to provision the defined resources in AWS.

This is because the whole purpose of standby instances is to prevent infrastructure failure. So, in case the primary goes down, the standby instance will help recover all of the data. So, when you go for an AWS Cloud Support Engineer interview, you will be tested on the infrastructure by asking questions related to network and storage.

What is a maintenance window in Amazon RDS? Will your DB instance be available during maintenance events?

This question also sheds light on your problem-solving skills and ability to enhance system efficiency, both of which are critical in the role of a Cloud DevOps Engineer. As a cloud DevOps engineer, you’re the custodian of your company’s cloud infrastructure, and that includes safeguarding the data stored therein. Data loss in the cloud can be a catastrophic event, and employers want to be confident that you have the skills and knowledge to prevent such incidents and to recover swiftly if they do occur. Therefore, this question is designed to test your knowledge of AWS’s data recovery measures and your ability to apply them effectively in a real-world scenario.

This ensures seamless integration and communication between on-premises and cloud environments, enabling workloads to be distributed effectively across both platforms. Once the assessment is complete, we design a target architecture in AWS, selecting appropriate services such as EC2 instances, RDS databases, or serverless options like Lambda functions. We also consider factors like scalability, high availability, and cost optimization during this stage. Data security is a top priority for any organization, and as an AWS Engineer, you’re expected to have a deep understanding of the best practices and tools available to protect sensitive information. Hiring managers have more expectations regarding your knowledge of big data, database management, system operations, and more. You’re more likely to engage with complex AWS technical interview questions than basic ones like those outlined in the section above.
