Boarding the journey for a successful cloud migration has
immense benefits associated. Scalability, cost-effectiveness and better
performance application to name a few! Cloud services provide the requisite
backbone for seamless accessibility and support. Hence, it is absolutely
natural to be inclined towards migrating to this platform.
But, this does not cease from the roadblocks, ensuring
restlessness. Abrupt costs, security
hacks, unforeseen rework of application might resist you from pursuing the
Nevertheless, the ace consulting companies have all of this
sorted, with their cloud solutions experts. You can have a chat with them, drop
an email and get your queries answered. The consulting firms like SA Technology
pave a smooth path owing to their transcendent cloud consulting services.
A well-thought-out migration strategy with an ability to
provide effective cloud solutions is the need of the hour for your organization.
In 2011, Gartner identified 5 migration strategies for the
same, which inculcate:-
Rehost- Rehost is redeployment of the application to a
disparate hardware environment. It alters the infrastructure configuration of
the application. Automated or manual tools can be utilized for this purpose.
If you have an application that is already executing on the
cloud, this procedure becomes further seamless.
Disadvantage: undoubtedly, when the rehost process is
pursued without altering the architecture, it yields faster result of cloud
migration solution. But, then you cannot overlook the risk associated with the
infrastructure owing to its consequences on the scalability.
Refactor- Cloud provides the infrastructure for running of
your application in this procedure. It is an amalgamation of familiarity with
uniqueness. It deploys PaaS. It implies, the developers are in the position to
reuse languages, containers and framework that they have invested in.
Disadvantage: framework lock-in, risks and missed aptitude
includes the disadvantage of this strategy.
Revise-Revise inculcates dual steps. The primary step
involves modification of existing code, which in turn provides support to the
requisites of legacy modernization. The next step is rehosting or refactoring
of the options to mobilize to the cloud. It aids in allowing the organization
and optimization of the cloud application to favor from the cloud attributes of
the infrastructure of the provider.
Disadvantage: this process will require higher expenses and
is time consuming.
Rebuild- Discarding the code for an existing application,
re-architecting of the application and thus rebuilding the solution of PaaS. Definitely,
this ensures loss of the cognition of existing codes and frameworks. However,
it also assures feasibility to the unique attributes in the provider’s
Disadvantage- Lock-in is the ace disadvantage.
Replace-utilization of commercial software delivered and
disposing of an existing application is pursued in this procedure. Investment
in the mobilization of a development team is not required.
Disadvantage- inconsistency in data syntactic, lock-in and
issues in data accessibility are expected.
As is evident from the above strategies, you need to come to
the decision after careful analysis. It is because you are not deciding just on
migration, but on optimization as well.
Consulting firms are the answer to all your queries.
