There can be numerous benefits of
migrating to the cloud, like scalability, improved efficiency, simplified
management, business agility and lower costs. Cloud migration can be considered
the start of a digital transformation for businesses, and enables organizations
to quickly adapt to the changes and latest technologies. It is important in
today’s changing business landscape to be able to adapt to the changes in
technology quickly. For these reasons and many others, it’s estimated that
about 83% of the business workloads will be in the cloud storage by the end of
As per the experts in cloud
storage, the desire of businesses to transform digitally is the driving factor
for increased cloud adoption and engagement. The introduction of cloud services
has changed the way information technology is consumed and delivered, which has
allowed companies to reach great innovation levels. While there are many
important benefits for cloud migration, there are also many challenges that
businesses face after migration.
Moving the infrastructure to critical
applications is a decision that businesses do not take lightly. Once the
decision is made, the planning and execution of the shifting should be
thoughtfully done considering the best options. However, many businesses regularly
fail to take into account post cloud migration considerations which should have
been done prior to migration. These considerations should be incorporated to
the overall plan of cloud migration. Failure to do so can result in problems
with underutilization, increased risks, confusion among employees and many
Below are some of the cloud migration
challenges that businesses might come across and should be prepared to handle.
Underutilization and Unbudgeted
Once the migration is completed, it’s important for businesses to follow
proper steps to make sure they get the most out of the cloud solutions. The
agility and flexibility offered by the cloud based solutions can be very beneficial
to businesses. However, it should be managed and controlled to keep issues like
underutilization, increased risk, unbudgeted costs, and compliance at bay. You
can follow the tips below to prevent these issues from happening.
various benchmarks and define targets in the important areas like cost,
RPO/RTO, availability, and compliance.
business governance with continual monitoring and measurement, combined with periodic
management review and oversight. In addition, operational and historical data
should be maintained.
- Employ ongoing
and proactive optimization of cloud across different tiers like cost. For
instance, proactive provisioning and planning to make use of the inherent flexibility
of cloud storage services using features like scheduled applications,
autoscaling, and environment health checks. It also includes buying reserved
instances, leveraging automation and DevOps to monitor actions and environments.
The actions can include division wide consolidated analysis and billing, shutting
down unwanted or unused instances.
- Educate yourself on how outsourcing to managed
service providers can help you save on costs and resources.
Management of Operational and
The biggest challenge might not
always be technology. It is usually the processes and people that need to adapt
to the technology. Employees from various departments should be involved and engaged
in the migration tasks, right from the beginning, even though the degree and type
of the activities will vary. Managing change, consistent with the other shifts
in IT is important for a successful transformation to the cloud storage
services. If you focus only on technology, it can lead only to poor results.
Executing applications in the
cloud can change the responsibilities and roles of many people across teams. This
includes human resources, compliance, and legal and can start new positions
like DevOps engineers, cloud architects, and security professionals. For this
reason, it is important for the leadership to offer proper education, ongoing
training and messaging to make sure that all the employees are completely
enabled, comfortable and capable doing their daily things.
Testing is a very important step
in the journey to cloud migration. Proper testing in place can help avoid unwanted
or unexpected gaps in scalability, business processes, database errors and server
breakdowns. Above all, having proper testing in place will ensure that all the
applications run seamlessly in the new environment.
Having proper security and monitoring
practices will ensure that the downtime is very low. With these measures, downtime
will not be much of an issue, but should be considered a challenge that
businesses should be prepared to confront. As per the results of a study
conducted on downtime, it can cost businesses an average of 5.6K dollars per
Businesses can consider adopting multi
cloud or multi location environment to avoid outages. There should be adequate backup,
disaster recovery, and availability strategies in place. It’s always better to
have workloads across varying locations, as it can add resiliency and cut down
the downtime risks.
Data breaches and thefts are occurring
at a very big rate and the risks that are associated to protect and guard data
are legitimate. It can be nerve wracking for businesses to offer the control of
proprietary and sensitive data to a third party. To get rid of security concerns
after cloud migration, you need to make sure that the cloud service providers
offer user identity management, secure authentication, and access control. When
functioning in a hybrid cloud environment, it’s important for the team to focus
on the physical security of the complete database and the environment.
Practicing secure data storage is
a necessity, as most of the data breaches and violations are caused by either
human errors (unintentional or intentional) or due to a failure in identity and
access control, data storage and data management security. Moreover, those
businesses that select a public cloud provider should understand that the
security standards have increased much in the last years. Security inside the
public cloud should involve partnership between the user and the service provider.
This means that it is very much important to have good understanding on the
ownership areas for security.
In the case of public cloud
storage systems like AWS, the well accepted and recognized security model is a
shared responsibility model. In this case, the service provider is the one who
is responsible for making the cloud secure. This includes hardware, physical
infrastructure and software, whereas the customer will be responsible for all
system security above platform, data, applications, operating system and
network traffic. Customers should be able to find out the best ways to handle
post migration responsibilities. For instance, they can use procedures, tools, and
managed service providers who have experience in cloud services.
You need to understand that
migrating from legacy infrastructure to the latest cloud storage is a serious
transition. But, if the businesses have an idea of the potential challenges
after the migration beforehand, they can be prepared to take the necessary actions
and steps to prevent it. Planning out the migration process and coming up with
a timeline designed to find and fix the problems quickly when they arise can
ensure a smooth transition.
