Section 15.140 Infrastructure as Code (IaC)

Question 1

Infrastructure as Code (IaC)

Answer 1

Modern approach to IT infrastructure management that automates provisioning and management through code

■ Used in DevOps and with cloud computing

Question 2

Idempotence

Answer 2

○ Operation consistently produces the same results

○ Crucial for consistency and reliability in multiple environments

Idempotence ensures identical environments. It is the abiity to produce the same results as many times as it is executed

Question 3

IaC Method

Answer 3

Developers and ops teams manage infrastructure through code

A method in which IT infrastructures are defined in code files that can be versioned, tested and audited

■ High-level languages like YAML, JSON, or domain-specific languages (e.g., HCL)
used

Question 4

Snowflake Systems

Answer 4

The main goal of IAC is to remove snowflake systems

Snowflake sysmtes: A configuration that lacks consistency that might introuduce risks, so it has to be eliminated

Question 5

Benefits of IaC

Answer 5

■ Speed and Efficiency (of development and deployment processes)

■ Consistency and Standardisation (environments set up same way)

■ Scalability (Operations)

■ Cost Savings (Manual configuration is not good)

■ Auditability and Compliance

Question 6

IaC Challanges

Learning Curve

Answer 6

● New skills and mindset required

● Teams learn to write, test, and maintain infrastructure code

Question 7

IaC Challanges

Complexity

Answer 7

● Infrastructure code can become complex

● Mitigated with modularisation and documentation

Question 8

IaC Challanges

Security Risks

Answer 8

● Sensitive data exposure in code files

● Insecure configurations may be introduced
