Problem Statement

Reality Gap

• Huge delta between what ought to be done and what actually happens, along multiple axes:
  • simplicity
  • reliability
  • security

Problem Statement

Expertise Gap

• Professionals have domain expertise, but few opportunities to gain technical expertise (with Cloud tech)
• Benefits of Cloud adoption are diluted by legacy bureaucracy

Stratagem

Reference Architectures

• Define organisation standards:
  • Security policies, firewall rules
  • Secrets management

Review

Problems/Pitfalls

• Change does not happen overnight
• Multiple initiatives must come together in order for adoption to be successful
• Scaling to meet client/user demand
• Know your target audience
