Monitoring Logging Security
Notifications
Service
Management/Ope
rations
Storage/Backup
Automation Roles/Policies High Availability
Disaster Recovery Fail over

3. General Questions First 10 Minutes
• Tell about yourself
• Can you please highlight your Cloud experience
• What are your day to day activities / What's your allocation for various activities
• Please take one cloud project and explain end to end

4. How do you build your Migration ?

5. How do you decide PAAS VS IAAS ?
• Load/traffic of the application
• Road map
• Required storage and how large the application
• What kind of components are required

6. What is your personal opinion on PAAS?
• Good and less management
• But at the same time vendor lockin
• Need to carefully evaluate and decide which components go on PAAS

7. What's your Cloud Approach in 2 lines
• Multi-Cloud Approach
• Hybrid approach ( Combo of PAAS and IAAS)

8. What's your evaluation process?

9. How do you convince your stake holders
• Story is different for each customer and need create approach based on requirement

10. How do you decide between Azure or AWS or
GCP
• Cost Evaluation
• Features requirement
• Region Availability
• SLA, HA, DR
• Security

11. What’s your HA and DR Strategy
HA – High Availability – Keep you applications 24X7
DR – Disaster Recovery - Get your applications and data back after a major disaster
RPO –Recovery Point Objective - Maximum tolerable period in which data might be lost from and IT Service due to major
incident
RTO – Recovery Time Objective -Maximum tolerable length of down time of your IT Service or Application
Strategy
Find/Define Applications to enable HA and DR
Business impact analysis
Set RPO/RTO
• Multi-Cloud Approach
• Hybrid approach ( Combo of PAAS and IAAS)

12. What’s your HA and DR Strategy
HA –
Availability sets
Availability zones
Auto scaling
Failover
Storage failover
Azure site recovery – VNet replication, VM replication
Levels of HA and DR -
Low - it can tolerate for few hours and tolerate of loosing few hours data
No fault isolation – 99.9% SLA
Take backups and restore the complete the system after a disaster –Blob storage
Medium - It can tolerate for 15 minutes to on hour -
Fault isolation with Racks and Storage – 99.95% SLA
Scale resources in the response to a DR event
Warm Standby – Can tolerate up to 15minutes
Availability zones with VM scaleset – 99.99% SLA
Scale resources in the response to a DR event - Azure Site Recovery
Hot standby – Real-time
Enable Multi-Site – Use Traffic Manager or Azure Front door to failover to different region

13. How do you Migrate Monolithic to Micro
Services and What are your considerations
• Analyze complete application and future needs
• Mainly based on
• size of the logic
• number methods
• interdependency
• Technology Can you please highlight your Cloud experience

14. How do you Secure Micro Services
• API Gateway
• Single point of entry to Micro services if we are exposing as platform
• WAF, Firewall
• SSL, Authentication, Authorization

15. How to communicate securely from one micro
service to another one
• Token based messaging to communicate between services

16. How do you enable security on cloud
• WAF
• Firewall
• Ddos
• VNet
• Azure Security Center
• Authentication, Authorization
• KeyValut
• Azure Sentinel

17. Which Database you prefer, Relation
Database vs No SQL ?

18. Business cases for Each type of DB
• SQL / RDBMS / Relational databases
• NoSQL / Non-relational databases
• Key-Value Stores
• Wide Column Stores
• Document Stores
• Graph Databases
• Search Engines

19. How do you convince when your two
developers have come up with 2 different
approaches
• Bring them to a meeting room and listen to both versions
• Ask them to give justification
• Put your thoughts
• If required, Involved other team members and conduct voting
