Throughout my career, I have gained extensive experience in testing both public and private cloud environments. In my previous role as a Cloud Testing Engineer at XYZ Company, I was responsible for developing and executing test plans for various cloud-based applications in both public and https://remotemode.net/ private cloud environments. This collection of the 100 best cloud interview questions and answers covers most of the essential topics you are likely to face in an interview. However, the world of cloud computing is always growing, so you should stay up to date on the newest advancements.
“Horizontal scaling over vertical scaling.” In the modern cloud, adding additional compute/networking/storage to an existing server (vertical scaling) is a trivial task. Balancing load across an auto-scaling group that adds/removes smaller instances is a better approach from a scalability, cost, and elasticity standpoint. Your architect should want to instinctually architect for horizontal scale from the start. In one of my previous projects, we had a multi-region architecture for our application to ensure high availability and low latency for global users. We used Route 53’s latency-based routing policy to direct user traffic to the region with the lowest latency.
How does AWS config work with AWS CloudTrail?
It turned out that there was an issue with one of the IAM roles being created, as it had insufficient permissions to perform certain actions required by the pipeline. Regarding Redshift, I worked on a project where we needed a powerful data warehousing solution for analyzing massive datasets. I helped set up the Redshift cluster, designed the schema, and optimized queries for faster execution. Additionally, I integrated Redshift with other AWS services like S3 and Glue for ETL processes and data ingestion.
- Finally, show off your technical skills by discussing the steps you would take to implement a machine learning solution on AWS.
- M5 instances, on the other hand, are also general-purpose instances but offer a balance between compute, memory, and networking resources.
- Additionally, by leveraging CloudFormation’s built-in functions and custom resources, I was able to incorporate dynamic configurations and integrate with other AWS services like Lambda and S3.
- I have also worked extensively with Route 53 for managing DNS records and routing policies.
- Retaining customer engagement and satisfaction is often correlated with how fast your product evolves to fix a bug or release a new feature.
So, if you expect more salary in your AWS job then answer each and every question asked by the interviewer clearly and confidently. In terms of complexity, I’ve dealt with multi-tier network architectures involving several subnets across multiple availability zones. This includes setting up route tables, internet gateways, NAT instances, and VPN connections. As a DevOps engineer, you are expected to not only understand the technical aspects of AWS but also how to strategically manage its resources.
How can you add an existing instance to a new Auto Scaling group?
AutoML Vision automates machine learning models for image analysis tasks, providing rapid and accurate predictions without requiring considerable machine learning skills. It enables cloud engineers to build custom ML models that perform a wide range of image analysis tasks without any significant investment needed for building it from scratch. When responding to cloud security issues, I identify the incident’s source, assess the breach’s degree, and apply countermeasures to mitigate the damage. It is also critical to notify stakeholders and document the steps taken to ensure a streamlined response. Regular monitoring and logging can also assist in detecting and preventing security concerns.
This method provides more control over the release process and enables real-time feedback on how the new version performs under actual user conditions. However, managing multiple versions simultaneously may require additional resources and complexity compared to blue-green deployments. AWS services like CodePipeline and CodeBuild are popular tools for creating and managing CI/CD pipelines.
Salesforce developer job description
Hiring managers ask this question to evaluate your expertise with AWS Lambda and your understanding of serverless application deployment. As an AWS Devops Engineer, you’ll be expected to maintain, develop, and optimize cloud infrastructure. Showcasing your experience with AWS Lambda and other related AWS services demonstrates your ability aws cloud engineer to effectively manage serverless applications and contribute to the organization’s cloud strategy. These cloud engineer interview questions dig into more specific cloud computing principles and strategies. Infrastructure as a service (IaaS) provides computing resources such as servers, storage, and networking over the internet.
- For example, creating and using subnets can help reduce congestion by making sure that the traffic destined for a subnet stays in that subnet.
- The data is encrypted to be unreadable without the correct decryption key (in case the device or system is lost or stolen).
- It provides foundational capabilities for the full breadth of AWS, without prescribing a particular model for development and operations.
- Unlike in EBS, data in an Instance Store is lost if any instance is stopped or terminated.
- This question is asked to evaluate your technical understanding of AWS and its features, particularly auto-scaling.
