EC2 (Elastic Compute Cloud) provides resizable compute capacity in the cloud, allowing users to run virtual servers. Lambda, on the other hand, is a serverless compute service that runs code in response to events without provisioning or managing servers. EC2 is ideal for long-running applications, while Lambda is suited for event-driven architectures.
How to Answer ItWhen answering, highlight the use cases for each service and mention scenarios where one might be preferred over the other.
To ensure security in AWS, I implement IAM roles and policies to control access, use VPCs to isolate resources, enable encryption for data at rest and in transit, and regularly audit security configurations using AWS CloudTrail and AWS Config.
How to Answer ItUse the STAR method to discuss a specific security challenge you faced and how you addressed it.
I use AWS CloudWatch for monitoring resource utilization and performance metrics, AWS CloudTrail for logging API calls, and AWS Config for tracking resource configurations. These tools help ensure optimal performance and compliance.
How to Answer ItMention the frequency of use and how these tools integrate into your workflow.
A Virtual Private Cloud (VPC) is a logically isolated section of the AWS cloud where users can define and control a virtual network. It allows for the creation of subnets, route tables, and security settings to manage resources securely.
How to Answer ItDiscuss the components of a VPC and their significance in cloud architecture.
AWS Identity and Access Management (IAM) allows users to manage access to AWS services and resources securely. It enables the creation of users, groups, and roles, along with defining permissions to control who can access what.
How to Answer ItExplain the importance of IAM in maintaining security and compliance in cloud environments.
I use AWS Cost Explorer to analyze spending patterns, set budgets, and monitor usage. Implementing tagging strategies helps track costs by project or department, allowing for better resource allocation and optimization.
How to Answer ItDiscuss specific tools and strategies you use for cost management.
AWS CloudFormation is a service that allows users to define and provision AWS infrastructure as code. It enables the creation of templates to automate resource deployment, ensuring consistency and repeatability.
How to Answer ItHighlight the benefits of using CloudFormation in managing infrastructure.
I implement a multi-region strategy for disaster recovery, utilizing AWS services like S3 for backups and Route 53 for DNS failover. Regular testing of recovery plans ensures readiness in case of an outage.
How to Answer ItDiscuss the importance of planning and testing in disaster recovery.
AWS Regions are geographical areas that contain multiple Availability Zones (AZs), which are isolated data centers. This architecture provides redundancy and high availability, allowing applications to remain operational even if one AZ experiences issues.
How to Answer ItExplain how this architecture impacts application design and reliability.
I stay updated by following AWS blogs, attending webinars, and participating in AWS training sessions. Engaging with the AWS community through forums and user groups also helps me learn about new features and best practices.
How to Answer ItMention specific resources and strategies for continuous learning.
