Challenges of Cloud
While the immense benefits of
shifting to a cloud model cannot be denied on any count, it is also
true that cloud comes with its fair share of challenges. IT
decision makers are often concerned with issues like data
governance, security, performance, reliability, loss of control,
integration and migration, cultural resistance and above all, the
difficulty involved in choosing reliable computing partners with
the required capabilities, market stability and experience to
support their unique goals and ambitions.
Let us have a closer look at some
of the major challenges of cloud:
Security:
- Data location and
privacy: Since a data center, in which data is
located, can be situated anywhere in the world, it can give rise to
apprehensions of the information being used by improper or wrong
elements.
- Loss of
data: Are the data recovery and backup process
adequately strong? In case there is a crash, what is the
downtime?
- Ownership of
data: If a user chooses to opt for another service
provider, he should get the data free of cost as per the export
feature. In other words, the user should have ownership of the
concerned data and not the cloud provider.
Design:
The following needs and challenges
of cloud computing need to be taken care of at the time of
application design:
- Scale-out design and rich user
interfaces
- Key-value non-RDBMS databases
- Different system resources need to
be utilized and monitored real-time for smart balancing of
load
- Authorization tickets need to be
easily passed across different parts of the application, especially
across two single sign-on premises
- Inability to scale RDBMS to cloud
computing requirements while key-value based databases have high
scalability
Integration:
Any company application needs to be
integrated with its other parts that are isolated geographically.
Cloud computing is capable of facilitating integration of
application parts operating in different premises. However, the
following issues of integration have to be resolved first:
- Techniques of data
synchronization
- Considerations related to
inter-application messaging such as company service bus
- Issues related to application
interfaces, partitioning and modularity like service-oriented
architecture
Portability:
An application developed in a
single platform cannot be ported to another one of a different
service provider without making significant code changes.
Application development standards need to be developed so that the
process of migration from one platform to the other becomes more
easy and effortless.
We sincerely believe that the best
way to tackle the challenges of cloud is to confront them head on.
We make use of our business and technical expertise to minimize the
risk for our clients as they embark on their cloud
journey.
