Using CloudTrail, you can get full details about API actions such as the identity of the caller, time of the call, request parameters, and response elements. On the other hand, AWS Config records point-in-time configuration details for your AWS resources as Configuration Items (CIs). EBS is a kind of permanent storage in which the data can be restored at a later point. When you save data in the EBS, it stays even after the lifetime of the EC2 instance. On the other hand, Instance Store is temporary storage that is physically attached to a host machine.
Private clouds are dedicated to a single organization and are usually located on-premises or in a data center owned by the same organization. Cloud engineering skills are topping the list of 2023’s most in-demand tech skills, with 75% of tech leaders planning to build all their new products and features in the cloud. “I have 5 9s tattooed on my arm.” Your cloud engineer should be motivated and proud of his past availability metrics. Customers, revenue, and reputation all suffer every minute your application is down. Consider downtime, measured in minutes, as one of the key performance indicators for your engineer.
Which type of scaling would you recommend for RDS and why?
As an AWS Cloud Devops Engineer, you’ll be expected to troubleshoot and solve complex technical issues, including latency problems. Interviewers want to see your problem-solving skills in action and learn more about your hands-on experience with AWS. They’re interested in your ability to diagnose, analyze, and resolve latency issues to ensure optimal system performance. They also want to know if you can communicate effectively about these problems and their solutions.
This is because the entire purpose of standby instances is to prevent infrastructure failure. As a result, if the primary instance fails, the backup instance will assist in recovering all of the data. This helps you understand the configuration changes that happen in your environment. This service provides an AWS inventory that includes configuration history, configuration change notification, and relationships between AWS resources. It can also be configured to send information via AWS SNS when new logs are delivered.
If you launch a standby RDS, will it be launched in the same availability zone as your primary?
Working with large datasets can be a challenge due to the sheer size and complexity of the data. As an AWS Data Engineer, you need to be able to troubleshoot and optimize data pipelines, ensure data accuracy, and work with large datasets. Interviewers want to know that you’re familiar with these challenges and have a strategy for dealing with them. There will also be situational questions to assess your leadership skills and behavioural aspects of your personality.
It also demonstrates your familiarity with DevOps practices, which are vital for the rapid and reliable delivery of software updates. The interviewer wants to assess your understanding of AWS infrastructure and your ability to design and implement a robust disaster recovery plan. This showcases your technical knowledge, strategic thinking, and problem-solving skills, which are all essential for an AWS Engineer.
Other than AWS, who are the main cloud service providers, and which ones have you worked with?
Additionally, AWS offers Spot Instances, which allow you to bid for unused capacity at lower prices, further optimizing costs without compromising performance. AWS provides various services through API calls, including public data storage, load balancing, scalability, and private software-defined networks. High availability and scalability are essential considerations when designing data engineering solutions on AWS. The interviewer wants to know if you understand the aws cloud engineer importance of these considerations, and if you can explain the strategies you use to ensure data engineering solutions are highly available and scalable. This includes understanding the use of AWS services such as Auto Scaling, Elastic Load Balancing, and CloudWatch, as well as best practices for designing for scalability and availability. This question helps interviewers understand your familiarity with AWS and your ability to work in a production environment.
- You might talk about implementing proper security protocols, using encryption technologies, or adhering to best practices for data storage and access.
- “Horizontal scaling over vertical scaling.” In the modern cloud, adding additional compute/networking/storage to an existing server (vertical scaling) is a trivial task.
- Familiarity with monitoring and logging tools like CloudWatch and CloudTrail is essential to proactively detect issues, troubleshoot problems, and maintain the overall health of the cloud infrastructure.
- The classic load balancer is used for simple load balancing of traffic across multiple EC2 instances.
- In traditional approaches, setting up an application environment involves numerous infrastructure components such as operating systems, database connections, and storage.
There are a number of different AWS-related questions covered in this article, ranging from basic to advanced, and scenario-based questions as well. An IT professional who helps create and maintain the cloud infrastructure is known as a cloud engineer. Under the cloud engineering umbrella, there are more specific roles, such as cloud architecting, development, and administration. A collaboration among networks, hardware, services, storage, and interfaces that are used in provident commuting as a service is known as a cloud. It has three users — end users, cloud service providers, and business management users.
