    Study Notes

    Change enablement

    • Normal changes are scheduled, assessed and authorized following a standard process.
    • Change models determine the roles for assessment and authorization depending on the type of change.
    • Some normal changes are low-risk and can be authorized quickly using automation.
    • Major changes can be authorized by higher management, such as the board of management.
    • Normal changes are initiated by creating a change request, which can be automated in organizations with a CI/CD pipeline.

    Emergency changes

    • Emergency changes are implemented as soon as possible to resolve incidents, such as implementing a security patch.
    • They are not scheduled and have an expedited assessment and authorization process.
    • Deployment management works closely with release management and change enablement.

    Deployment management

    • Deployment management is a separate practice from release management and change enablement.
    • Deployment is used to describe the deployment of both infrastructure and software.
    • Categories of releases include major releases, minor releases, and emergency releases.

    Major Releases

    • Introduce new hardware or software.
    • Introduce completely new functionality.
    • Example: v1.0 and v2.0 releases.

    Minor Releases

    • Make improvements to existing functionality.
    • Package together a number of fixes.
    • Example: v1.1, v1.2, v1.3.

    Emergency Releases

    • Implemented to address urgent issues.
    • Often temporary fixes.
    • Example: v1.1.1, v1.1.2, v1.1.3.

    Deployment approaches

    • Organizations use a combination of deployment approaches.
    • Big bang deployment: Deploying new or changed components to all targets at the same time.
    • Phased deployment: Deploying new or changed components to parts of the production environment, gradually rolling out to the entire environment.

    Infrastructure & platform management

    • People, processes, and documentation are not traditionally considered part of IT infrastructure, even though they play significant roles in managing it.
    • IT Infrastructure Managers require specific skills in deploying, setting up, directing changes, and understanding the architecture, budgeting, specifications, and strategic purpose of infrastructure.

    Infrastructure software vs business application software

    • Infrastructure software enables IT processes.
    • Business application software enables business processes.

    Infrastructure software examples

    • Server operating systems such as Windows, Linux, AIX, IBM i, HP-UX.
    • Middleware applications.

    Business application software examples

    • ERP systems.
    • Visual Basic programming applications.

    Platform as a Service (PaaS)

    • PaaS offers advantages for businesses of all sizes.
    • Advantages:
      • Simple and cost-effective development and deployment of apps.
      • Scalability.
      • High Availability.
      • Customization without maintaining the software.
      • Reduced coding requirements.
      • Automation of business policies.
      • Easy migration to the hybrid model.

    PaaS characteristics

    • Builds on virtualization technology for scalability.
    • Provides services for development, testing, and deployment of apps.
    • Accessible to multiple users via the same development application.
    • Integrates web services and databases.

    When to use PaaS

    • PaaS is helpful for multiple developers working on the same project.
    • PaaS provides speed and flexibility for projects involving vendors.
    • PaaS is beneficial for creating custom applications.
    • PaaS reduces costs and simplifies challenges in rapid development and deployment.

    Infrastructure as a Service (IaaS)

    • IaaS provides highly scalable and automated compute resources.
    • Advantages:
      • On-demand purchasing of resources, avoiding hardware purchases.
      • Complete control over infrastructure through a dashboard or API.
      • Outsourcing of physical maintenance and management.
      • Access to servers and storage directly through a virtual data center in the cloud.

    IaaS delivery

    • IaaS delivers cloud computing infrastructure through virtualization technology, including servers, network, operating systems, and storage.
    • Clients manage applications, runtime, OSes, middleware, and data.
    • Providers manage servers, hard drives, networking, virtualization, and storage.
    • IaaS providers may offer additional services beyond virtualization, such as databases or message queuing.
