BSIT 400 - Cloud Computing and Governance.
Migration to the Cloud
Technology has transformed and revolutionized our ways of
achieving and accomplishing dreams and goals since its existence. The
introduction of cloud computing has taken it even further. The purpose for this
week three blog topic is center around “Migration to the Cloud.” There are a
variety of contents and activities involved with cloud migration, and it’s
imperative for one to fully understand all these contents and activities involved
for a smooth transition. Some of these contents are but not limited to, Migration
Planning, Migration Execution, Deployment Testing and Validation, Cloud
Agility, and Planning for Problem. This week three blog is going to focuses on
the following contents and activities:
1. Migration
Planning
a. Cloud
Migration Phases – this activity involved completing the most important phases
contents which are Planning, migrating, validating, and managing. These migration
phases are important and should be completed when decisions are being or has
been make before transiting any resources to the cloud – especially in an IT
environment where some or the entire organization IT resources like,
applications, server, databases, and so on, are being move.
b. Transition Assessment – it is never a
good idea to migrate without any assessment to figure out if it’s a good strategy
in the first place for your operation. The purpose for assessment comes down to
the fact that not all applications, services or databases will perform
perfectly in the cloud. cloud. Legacy software, especially, might not be
compatible with the cloud environment. Latency is the delay between the
transmission of a signal and its receipt, and this physical reality might make
certain cloud-hosted services unreasonably slow. In fact, latency is the most
often-cited reason for a company’s return to its own data center after trying a
cloud deployment (West, p. 81).
c. Migration
Plan – this activity is by far considered to being the most challenging
regarding cloud migration. Nevertheless, it may not be as challenging as you
expect if a well-executable plan is implemented for the migration process.
There are going to be various plans based on the business operation in the
cloud (migrating applications, databases, or network operation). An effective
and well thought-of plan can contain aspects like: Baselines, Business Continuity,
Existing System, Target Hosts, Cloud Architecture, Legal Restrictions, and
Order of Operations.
d. Migration
Strategies – like the saying goes, “not one side fit-all.” The same goes
for cloud migration, every organization has its own unique ability approach when
migrating to the cloud based on the elements that are being migrated directly
to the company intending the transition. The purpose for such intent “can range
from wanting to save money to over-hauling their entire IT infrastructure and
anything in between” (West, p. 83). Intent of choosing what approaches to
pursuit for specific resources, try considering opposite elements “both from a
business perspective and from a technical perfective.” For example, one could
be, can such an application generate income, or can and will the application subsidize
business process?
e. Timing
– this may be seen as the last phase in the migration planning process, but it
is just as important as all the others regardless. As you approach the end
where all the important aspects and decisions has been made and consider
regrading migrating to the cloud and the all the migrating plans are connected,
the timing begins for the “workload migration.” Environmental constraints
require careful scheduling to minimize the impact of downtime and maximize the
available network bandwidth for the migration (West, p. 85). The following are
elements that should be considered: Impact of Downtime, Work Hour Restrictions,
Time Zones, Peak Time Frames and Costs.
There have been lots of successful and unsuccessful stories told
and written about migrating to the clouds by business organizations. The
success of migrating to the cloud will heavily rely and depend on the readiness
of the business organizations. Planning and researching should be the two up-front
approaches implemented and always followed.
