Core Cloud Operational Strategies Flashcards
| Front | Back |
| Define High Availability in AWS | The ability of a system to remain operational and accessible even when components fail, typically achieved through redundancy across multiple Availability Zones. |
| Describe the purpose of AWS IAM | AWS Identity and Access Management (IAM) enables you to securely control access to AWS services and resources for your users. |
| Explain the concept of a Blue-Green Deployment | A deployment strategy where two identical environments (blue and old, green as new) exist simultaneously, allowing for seamless cutover with minimal downtime. |
| How does AWS implement Multi-AZ deployments? | By automatically provisioning and maintaining a synchronous standby replica in a different Availability Zone to provide data redundancy and failover support. |
| What are Amazon CloudWatch Alarms? | They monitor metrics over a time period you specify and perform actions based on the metric's value relative to a threshold. |
| What are AWS Config Rules? | Predefined or custom rules that evaluate the configuration settings of your AWS resources for compliance and best practices. |
| What are AWS Trusted Advisor checks? | Automated checks that analyze your AWS environment and recommend improvements across cost optimization, security, fault tolerance, performance, and service limits. |
| What are the key components of the AWS Well-Architected Framework? | Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability. |
| What does RPO stand for in disaster recovery? | Recovery Point Objective - the maximum acceptable amount of data loss measured in time. |
| What does RTO stand for in disaster recovery? | Recovery Time Objective - the maximum acceptable time it takes to restore a system after a disruption. |
| What is a Maintenance Window in AWS? | A scheduled time period designated for performing system updates, patches, and other maintenance tasks with minimal impact on production workloads. |
| What is Amazon CloudWatch Logs? | A service that enables you to centralize logs from AWS resources, applications, and on-premises servers for monitoring and analysis. |
| What is Amazon EventBridge? | A serverless event bus that makes it easier to build event-driven applications at scale using events from your applications, SaaS applications, and AWS services. |
| What is Amazon GuardDuty? | A threat detection service that continuously monitors for malicious activity and unauthorized behavior in your AWS accounts and workloads. |
| What is an AWS Health Dashboard? | A service that provides personalized information about events that might affect your AWS infrastructure, guides through scheduled changes, and accelerates troubleshooting. |
| What is an AWS SLA? | Service Level Agreement - a formal commitment about the expected level of service availability that AWS provides to customers. |
| What is Auto Scaling in AWS? | A feature that automatically adjusts the number of compute resources based on demand to maintain application availability and reduce costs. |
| What is AWS CloudFormation? | A service that helps model and set up your AWS resources using infrastructure as code. |
| What is AWS CloudWatch? | A monitoring and observability service that provides real-time data and insights for AWS resources and applications. |
| What is AWS Cost Explorer? | A tool that enables you to visualize, understand, and manage your AWS costs and usage over time. |
| What is AWS Systems Manager? | A management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure operating systems. |
| What is AWS X-Ray? | A service that helps developers analyze and debug production, distributed applications, especially those built using microservices architecture. |
| What is the AWS Service Health Dashboard? | A public page that shows the general status of AWS services, while the Personal Health Dashboard shows events specific to your account. |
| What is the AWS Shared Responsibility Model? | A security framework that defines which security controls are AWS's responsibility (of the cloud) and which are the customer's (in the cloud). |
| What is the purpose of AWS CloudTrail? | It records and logs all API calls made within your AWS account for auditing, compliance and security analysis. |
