Advertisements help us provide users like you 1000’s of technical questions & answers, algorithmic codes and programming examples. Launched in 2006, EC2 is a virtual machine that you can use to deploy your own servers in the cloud, giving you OS-level control. It helps you have control over the hardware and updates, similar to the case of on-premise servers. GCP is often considered the cheapest provider of cloud computing services, though prices have leveled out over time. Unlike VMs, containers share the host operating system but are isolated from each other at the application and process level. As a result, containers are even better at helping to minimize unused computing capacity (2-3x more efficient).
- An Elastic Load Balancer ensures that the incoming traffic is distributed optimally across various AWS instances.
- Used for transparently monitoring and amazing dataflows, the monitoring agent keeps track of the network traffic along with the message metrics.
- 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.
- Businesses use cloud computing in part to enable faster disaster recovery of critical IT systems without the cost of a second physical site.
Demonstrating your knowledge of this concept and explaining its benefits showcases your expertise in AWS and your ability to leverage its tools to create efficient and cost-effective cloud environments. One notable project involved deploying a multi-tier web application with load balancing and auto-scaling features. Using CloudFormation, I created templates that defined all necessary resources, such as EC2 instances, RDS databases, Elastic Load Balancers, and Auto Scaling Groups. These templates enabled version control and simplified updates to the infrastructure when needed.
#2: Can you explain the purpose and use of Azure’s load-balancing services?
Start by talking about the AWS services you’re familiar with and have used for deployments. Then, provide a few examples of applications that you’ve deployed to production environments on AWS. Be sure to discuss any issues you faced during the process and how you were able to solve them. If you have experience writing scripts in Python or another language, be sure to mention it and give examples of how you’ve used scripting to automate tasks. If you don’t have any direct experience with scripting, talk about the steps you’d take to learn a new language and how you might apply that knowledge to your job.
- Geo-Targeting is a concept where businesses can show personalized content to their audience based on their geographic location without changing the URL.
- Connection Draining is an AWS service that allows us to serve current requests on the servers that are either being decommissioned or updated.
- You may or may not be asked about the basic questions on Cloud Computing and AWS Cloud.
- If you’re looking for more interview questions for other AWS job roles, check out our previous article that covers the top 50 AWS interview questions.
- 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.
This setup required comprehensive monitoring using CloudWatch and third-party tools for log management and alerting. Elastic Load Balancer distributes incoming application traffic across multiple targets, such as EC2 instances. AWS cloud playing a significance role in rapid scale of production growth for both startup and MNC companies with automation and management of workflow seamlessly. In order to design a disaster recovery plan, creating backups across the regions on replication of important data implementing cross-regions must be implemented. Definition of recovery time objectives (RTO) and recovery point objectives (RPO) must be specified. For the automation of cross-region replication try on using the services like AWS Backup for centralized backup management and AWS Elastic Disaster Recovery (EDR) for automating cross-region replication.
Top 10 Scenario-Based Questions I Always Ask in All AWS Cloud Engineer Interviews (Detailed Answers Included)
You can check our article on AWS cloud support engineer salary in the US and see the compensation details. A monitoring agent is an intermediary and event-driven program created as a service agent and placed along the existing communication paths. Used for transparently monitoring and amazing dataflows, the monitoring agent keeps track of the network traffic along with the message metrics. Function as a Service (FaaS) offers users a aws cloud engineer platform where they can develop, manage, and run their applications without worrying about the infrastructure’s maintenance. S3’s most crucial aspect is its support for integrations with AWS services, which allows for creating sophisticated application architectures. S3 intelligent tearing analyses workload using machine learning algorithms and automatically transitions objects from S3-to-S3 standard with free access after 30 days.
- Troubleshooting AWS performance issues deals in analyzing metrics of CloudWatch, Examining logs, and using of AWS X-Ray service for tracing.
- Therefore, your interviewer needs to know if you have the necessary practical experience and understanding to effectively handle these tasks.
- Using an application load balancer, the traffic can be routed based on the requests made.
- Scalability handles the changing needs of an application within the boundary of the infrastructure via statically adding or removing resources to meet the application’s demands if needed.
