• Can use as backup and disaster recovery solution

Question 13

List 5 pillars of a well architected framework

Answer 13

• Build the most secure, durable, efficient, and high-performing IT infrastructure possible -
  5 Best Practices
• Avoid unnecessary costs: use what you need, reserve resources in advance, continue to monitor for optmization
• Reliability - Disaster recovery settings and options, incorporate redundancy, duplicate copies of resources
• Efficiency
• Security - Information, systems, and assets, should be secure. Best practices should be automated, data should be protected when stored and when in transit, enable traceability, Manage access
• Operational Excellence - Monitor and maintain services while constantly improving processes and procedures - Document everything, refine, operational procedures, anticipate failure, update processes

Answer 14

• Public cloud
• Hybrid cloud
• Private cloud (On-prem cloud)

Question 15

What are compute services?

Answer 15

• Virtual server hosting, container management, server less computing
