Which scaling method is an example of changing to a larger EC2 instance; where you change the instance type and family?
Vertical
What are the limitations of scaling vertically?
- Often requires manual intervention
- Typically requires downtime
- Can reach a limit of scalability
What scaling type is where you add more of the same instance?
Horizontal
What are the benefits of horizontal scaling?
- Seamless scaling without downtime
- Can scale almost limitlessly
What are the following categories together called? Disposable resources instead of fixed servers; automation; loose coupling; server, not servers; databases; removing single points of failure; optimize for cost; caching; & security
AWS Best Practices
Which AWS Best Practice allows customers to take advantage of dynamically provisioned resources and nature of cloud computing?
Disposable resources instead of fixed servers
Which AWS Best Practice improves system stability and organization efficiency?
Automation
Which AWS Best Practice reduces interdependentcies where a change or a failure in one component should not cascade to other components?
Loose Coupling
Which AWS Best Practice allows customers to leverage more than just Amazon EC2 and provides a breadth of services on AWS?
Service, not servers
Which AWS Best Practice considers performance requirements and scalability by selecting the right database technology for each workload?
Databases
Which AWS Best Practice uses design to fail, introduce redundancy, detect failure, durable data storage, and automated multi-data center resilience?
Removing Single Point of Failure
Which AWS Best Practice focuses on right sizing, elasticity, and takes advantage of the variety of purchasing options?
Optimize for Cost
Which AWS Best Practice is used to improve performance and cost efficiently and methods include Edge Caching & Application Data Caching?
Caching
Which AWS Best Practice focuses on defense in depth, reduced privilege access, security as code (CloudFormation), and real-time auditing?
Security
What are the 5 Pillars of Operational Excellence?
- Operational Excellence
- Security
- Reliability
- Performance Efficiency
- Cost Optimization
Which pillar of Operational Excellence provides the ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures?
Operational Excellence
Which pillar of Operational Excellence provides the ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies?
Security
Which pillar of Operational Excellence focuses on a system’s ability to recover from infrastructure of service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues?
