cloud migration
Finally, this phase may play a
role in removing an application
from migration consideration if it
is determined that the migration is
infeasible due to security concerns
or service level requirements.
it might seem challenging to
guarantee a seamless end-user
experience during the move,
so it is no wonder that many
organisations continue to
hesitate over moving to the cloud.
However, data centre migration
need not be painful and costly. It
just comes down to visibility.
Visibility
A journey of discovery
Before embarking on a migration,
it’s critical to have an in-depth
understanding of applications and
their dependencies. Observed,
real-time application mapping
is the most efficient, thorough,
and accurate way to gain this
understanding. This process
also has the added benefit of
identifying redundancies and
inefficiencies to help improve
overall performance once the
migration is complete.
This discovery phase is critical
as it helps to define a candidate-
list of systems to migrate,
which is vital within multi-tier
applications that have subsystems
that effectively make up the
application itself. This allows the
creation of a plan to group devices
logically and create a complete,
contained view of the application.
This phase can also be
helpful in understanding which
departments and users are
accessing the application, allowing
the proper setting of expectations
should there be the need for
planned downtime during the
migration. It can also be a great
way to prioritise which applications
need to move first. For example, a
sales database that plays a critical
role in order processing might be
prioritised over a human resources
database that contains less time-
sensitive information.
