DevOpsPorto Meetup19: Infrastructure as code - a DevOps Enabling Tool by Diana Martins

With the appearance of DevOps, a product’s lifecycle stops being about separate stages conducted by independent teams. It transitioned to a continuous process carried out by teams sharing knowledge, thoughts, opinions, and tools. IaC tools allow infrastructure deployment and configuration management through code, proving themselves as a strong link element between devs and ops.

   ‣ DBAs;
   ‣ Release managers;
   ‣ Security;
   ‣ Monitoring;
   ‣ Maintain.
   DEVELOPERS
   ‣ Gather requirements;
   ‣ Write code;
   ‣ Write automated tests;
   ‣ Manual testing;
   ‣ Refactor;
   ‣ Create.

   DEVOPS
   The philosophy
   Practice that assumes the joint participation of ops engineers and
   developers in a product’s lifecycle since the design, passing through
   the development, until production and support processes.

    DYNAMIC INFRASTRUCUTURE: CHALLENGES
    Infrastructure as Code
    ‣ Server sprawl;
    ‣ Configuration drift;
    ‣ Snowflake servers;
    ‣ Fragile infrastructure;
    ‣ Automation fear;
    ‣ Erosion.

    PRINCIPLES
    Infrastructure as Code
    ‣ Systems are:
    ‣ Easily reproducible;
    ‣ Disposable;
    ‣ Consistent;
    ‣ Processes can be repeated;
    ‣ Design is always changing.

12. ADVANTAGES
    ‣  Infrastructure versioning;
    ‣  Process automation;
    ‣  Self-documented infrastructure and
    processes;
    ‣  Processes’ and systems’ testability.
    DISADVANTAGES
    ‣  Can bring disruptive changes to
    processes;
    ‣  Demands processes’ standardization
    and exhaustive description before
    execution;
    ‣  Wrong configurations are spread across
    every machine;
    ‣  Marginalizes hotfixes.

    CONFIGURATION MANAGEMENT
    Infrastructure as Code
    ‣ Rapidly transform a server:
    ‣ Install requirements;
    ‣ Easy reconfiguration;
    ‣ Avoids dependency problems;
    ‣ Installation and configuration processes are stored as code;
    ‣ Cures deployment pains allowing:
    ‣ Blue/green deployments;
    ‣ Rolling deployments.
