The document discusses continuous delivery (CD) which is an automated process for delivering packaged software into production or testing environments. It describes the key phases of CD - deployment, operations, monitoring, and releasing. Deployment includes making software available for use. Operations involves server configuration. Monitoring collects and analyzes data. Releasing determines when to release software changes. The document provides examples of tools used in each phase like Chef, Jenkins, Ansible, and Nagios.

Continuous Delivery
• Continuous delivery (CD) is an automated process for
delivering packaged software artifacts into a production or
testing environment.
• CD automates the complete delivery process including new
features, configuration changes, and bug fixes.
• Generally, CD includes provisioning infrastructure resources,
handling changes, deploying software artifacts, validation,
and monitoring.

Deployment
• Deployment includes all the activities and artifacts that
make a software system available for use.
• In continuous delivery this activity occurs automatically and
frequently.
• The exact processes within the activities will depend on the
software to be deployed.
• In DevOps this is also referred to as continuous deployment.

On Premises (On-Prem), Clouds & Containers
Containers:
A unit of software that packages up
code and all its dependencies in a
single resource. Technologies such
as Docker are used to create and
deploy applications in containers
which allow them to run quickly
and reliably from one environment
to another.
Cloud:
Organizations that deploy to the cloud rely
on cloud providers to host the system
resources required. Virtualization or VMs
implemented across vast data centers allow
for a near unlimited combination of system
configurations.
On-Prem:
On premises deployments involve
physical hardware such as servers or
machines hosted on location at an
organization’s site.

Operations
• In DevOps, the operations team takes care of server
configuring, scaling, load balancing and provisioning.
• Development cycles are much shorter in DevOps which
forces DevOps operations teams to use an automated
approach to accelerate the time-to-market for the software
application.

Monitoring
• The Monitoring phase usually occurs in parallel to the operations
phase and consists of data collection, analysis, and feedback
throughout the pipeline as needed.
• In sophisticated environments, optimization is automated as
continuous optimization (CO), an extension of the CI/CD pipeline
that leverages machine learning and artificial intelligence to
eliminate risks and waste associated with manual infrastructure
processes.

Releasing
• Once all previous phases have been completed, the team
can determine a release candidate.
• At this point, it can be decided which changes should be
included in a release.
• Depending on the maturity of the release process, this can
be a manual or an automatic step.
• Some companies deploy new versions of software on a
fixed schedule, while others do this automatically as soon
as new code has successfully passed all previous phases.
