10 common platform engineering interview questions

When an EC2 instance is launched, a private IP address is assigned to that instance at boot time. This private IP address is attached to the instance for its entire lifetime and can never be changed. A bigger RDS instance type needs to be opted for handling large amounts of traffic, creating manual or automated snapshots to recover data in case the RDS instance goes down. EBS volume consists of virtual drives that can be easily backed up and duplicated by snapshots. Another less obvious perspective is that an engineer who has designed a well-architected, self-healing stack sees pages as informational heads-ups, not drop-everything action items. Reserved instances and on-demand instances are the same when it comes to function.

  • Infrastructure as Code (IaC) is a practice that automates the provisioning and management of IT infrastructure, allowing for faster, more efficient, and more reliable deployment of resources.
  • Cloud engineers must have a solid understanding of the technical aspects of AWS, and this question aims to evaluate your knowledge of IP addresses within the platform.
  • Its main advantage is its multi-cloud compatibility, allowing you to manage infrastructure across various cloud providers like AWS, Azure, Google Cloud Platform, and more.
  • Finally, you test the auto-scaling solution to ensure it works correctly and that the scaling criteria, alerts, and actions are appropriately configured and deploy it to your production environment.
  • For example, an API can automatically provision and configure new cloud resources as needed based on specific conditions or triggers.

It also demonstrates your familiarity with DevOps practices, which are vital for the rapid and reliable delivery of software updates. 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. Diving into the technical details of a specific task like creating a custom Virtual Private Cloud (VPC) in AWS allows interviewers to gauge your hands-on experience and expertise in the field. A VPC is the best way of connecting to your cloud resources from your own data center. Once you connect your datacenter to the VPC in which your instances are present, each instance is assigned a private IP address that can be accessed from your data center.

How do you configure CloudWatch to recover an EC2 instance?

Grasping the fundamentals of AWS architecture is a key factor for a cloud engineer’s success. Interviewers ask this question to assess your understanding of the various services, their functions, and how they integrate with each other. Your answer will demonstrate your technical knowledge and showcase your ability to design and implement effective solutions within the AWS ecosystem.

This model has a delay in writing the data, but it guarantees that you will always see the updated data every time you read it. Here’s an example of an IAM policy to grant access to add, update, and delete objects from a specific folder. By enabling this Connection Draining, we let the Load Balancer make an outgoing instance finish its existing requests for a set length of time before sending it any new requests.

What are the factors to consider while migrating to Amazon Web Services?

Software as a Service (SaaS) delivers software via the internet, removing the requirement for on-premise installations. Infrastructure as a service (IaaS) provides computing resources such as servers, storage, and networking over the internet. Customers https://remotemode.net/become-an-aws-cloud-engineer/ have control over the operating systems, storage, and deployed applications that run on infrastructure — but the provider manages the underlying infrastructure. With IaaS, companies no longer have to purchase, store and maintain their physical servers.

Further, having good knowledge of DevOps, APIs, and NoSQL will only improve your chances of getting hired. So prepare a strategy that includes cloud engineer interview questions based on all these topics. This can turn out to be one of the most common AWS cloud support engineer interview questions asked by the interviewer. So, before going on such interviews clear your doubts about the network, infrastructure, and other relevant topics. “I don’t like managing my own clusters.” If candidates pride themselves in how they operated a 15-node cluster, it might be a red flag.

#2: Can you explain the difference between a private cloud, public cloud, hybrid cloud, and multi-cloud ecosystem?

Providing the example at the end lets you add that little something extra to your response without going too far. It’s a way to highlight your expertise when you’re answering AWS cloud engineer interview questions a little bit more, which can make a difference. 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 private cloud environments.

Service Level Agreements (SLAs) are contracts between service providers and their customers that outline the specific services that will be provided and the level of service that the customer can expect to receive. Service Level Agreements (SLAs) often encompass availability, security, performance, customer support, and compliance. It is critical to thoroughly analyze your cloud infrastructure before developing strategies to create a secure environment and protect the ecosystem from data breaches. CI/CD (Continuous Integration/Continuous Deployment) pipelines streamline the process of integrating, building, testing, and deploying software in cloud computing environments. To achieve maximum performance from a virtual machine, you can use tactics such as resource consumption monitoring and select the appropriate operating system and hardware configuration.
