Software
deployment
The general deployment process consists of several
interrelated activities with possible transitions between
them. These activities can occur at the producer site
or at the consumer site or both. Because every software
is unique, the precise processes or procedures within
each activity can hardly be defined. Therefore, "deployment"
should be interpreted as a general process that has
to be customized according to specific requirements
or characteristics. A brief description of each activity
will be presented later.
Deployment activities
Release
The release activity follows from the completed development
process. It includes all the operations to prepare a
system for assembly and transfer to the customer site.
Therefore, it must determine the resources required
to operate at the customer site and collect information
for carrying out subsequent activities of deployment
process.
Install
The Install is the initial insertion of software into
a customer site. Currently, this activity is best supported
by specialized tools. The two sub-activities are transfer
and configure. The former is to move the product from
the producer site to the customer site, while the latter
one refers to all the configuration operations that
make the system ready for customer uses.
Activate
Activation is the activity of starting up the executable
component of software. For simple system, it involves
establishing some form of command for execution. For
complex system, it should make all the supporting systems
ready to use.
In larger software deployments, the working copy of
the software is typically installed on a production
server in a production environment. Other versions of
the deployed software may be installed in a test environment,
development environment and disaster recovery environment.
Deactivate
Deactivation is the inverse of activation. It is to
shut down every executing component for an installed
system.
Update
Updating is a process of installing a new version of
a system / software. It can be considered as a less
complex installation process since many of the needed
resource have already been inserted during the installation.
So, same to installation, it includes sub-activities
of transfer and configure.
Adapt
The adaptation activity is also a process to modify
a software system that has been previously installed.
It differs from updating in that adaptations are initialed
by local events such as changing the environment of
customer site, while updating is mostly started from
remote software producer. eInsert non-formatted text

Uninstall
Uninstallation is the inverse of installation. It is
a remove of a system that is no longer required. It
also involves some reconfiguration of other software
systems in order to remove the uninstalled system’ files
and dependencies. This is not to be confused with the
term "deinstall" which is not actually a word.
