A recent Gartner Report identified five Cloud computing trends
which could affect the cloud strategy through 2015. While Cloud Computing has a
significant potential impact on every aspect of IT, the uncertainty, confusions
and misunderstandings continue to exist and the five sub trends would be accelerating
and need to be factored into the planning process. This means that the CIOs
would be inclined to revise the cloud strategies to align with these trends. This
will also mean that the enterprises would need IT workers with skills that
could help in making this strategic shift successful. Here are the five sub trends and the skills that these trends would demand.
Formal Decision Frameworks facilitate Cloud Investment
Optimization
The benefits of cloud include the shift from CAPEX to OPEX
models, reduced spending, greater agility and reduced complexity. These
benefits do not come just like that and they come with some challenges in the
form of security, lack of transparency, performance & availability concerns,
vendor lock-in, licensing constraints and integration needs etc. It is
important that these benefits and concerns are carefully mapped against the
needs of the enterprise and an appropriate decision is made and necessary monitoring and management processes are put in place. Each of these
benefits needs to be quantified considering the organization’s current and future
priorities and constraints. For instance, a financial services firm may find
the greater agility as a challenge as well (as against a benefit), because, greater agility could mean
more frequent changes, which would have an impact on the reliability and
stability of the applications. Realizing such impact in mid-course could result
in rolling-back from cloud adoption and the resulting impact is obvious.
Over the next few years, organizations would be putting in appropriate
decision frameworks, more specifically for the cloud adoption so that the benefits
and risks are known upfront and decisions are taken appropriately. The skills
that this trend may demand include Risk Management, IT Security, IT
Governance, Estimation and Metrics.
Hybrid Cloud Computing as an Imperative
As there are enough reasons for
enterprises not moving all their IT on to public cloud, Gartner sees a unified
cloud model, where a cloud of clouds is a possibility, in which a single cloud
may comprise of multiple cloud platforms part of which could be it internal. As
everyone know, the key challenge with hybrid cloud computing is the integration
of application and data between on-premise and cloud applications.
This calls for existing internal
applications being enhanced to support integration with external cloud applications
and at the same time the cloud applications should expose APIs for consumption
by other cloud applications and / or the organization’s internal applications. Applications
on public cloud need to adhere to industry standards and best practices, so as
to support varying integration needs of its customers. The skills that an IT
professional would start seriously looking at to get on with this trend are EAI
(Enterprise Application Integration), SOA (Service Oriented Architecture), ETL
(Extract Transform and Load) and EII (Enterprise Information Integration).
Cloud Brokerage will facilitate
Cloud Consumption
As cloud adoption proliferates, so
does the need for consumption of assistance. Gartner believes that Cloud
Service Brokers (CSB) are one of the most necessary and attainable
opportunities for service providers, service distributors and internal IT
organizations. The CSB model provides an architectural, business and IT
operations model for enabling, delivering and managing different cloud services
within a federated and consistent provisioning, billing, security administration
and support framework. This will help the unification of the cloud services delivery
and management. Gartner has designated Jamcracker as a “Cool Vendor in Cloud
Service Brokerages”.
This trend will call for the IT
professionals to have a great deal of knowledge on SOA in addition to various
standards, practices and tools on service provisioning, delivery monitoring,
billing and management.
Cloud-Centric Design becomes a
necessity
Migrating existing workloads with highly
variable resource needs to cloud platforms is among the immediate opportunities
that many organizations are looking at utilizing. But this will not make the
cloud adoption complete, as it will result in using various work-around
approaches to make it work with existing applications, by-passing standards and
best practices. This might work in the near term and but may not scale and
yield the real benefits in the longer term. Organizations should start looking
at development of cloud-optimized applications that exploit the potential of
the cloud. Even internal applications should be designed with cloud-centric
model, so that it can exploit the private cloud platform and would make the
integration with public cloud applications easier over hybrid cloud computing
platforms.
This trend will expect the application
and solution architects to start acquiring necessary cloud skills, so that the
solution that they architect is cloud-centric and will have identifiable
service end points for use with various other internal and external applications
and also factor in the support for Cloud Service Brokerages. The design
patterns, standards and practices around cloud-centric design is evolving and
it is important for the IT workers to keep a watch in this area.
Cloud Computing influences future
Data Center and Operational Models
In public cloud computing, the
providers have implemented such a model so that the ability of provisioning,
delivering and managing the services is optimized and automated to a great
deal. This also ensures optimal utilization of the underlying hardware and also
minimizing the energy and other operational costs. Enterprises are attempting
to implement the similar models within their data centers and have private
clouds setup for the consumption of their own internal consumers. This trend is
increasing and Gartner predicts that in the next few years any data center
(small or big, internal or external) implementation would follow the cloud
model.
This trend will expect the
Infrastructure Architects to be cloud aware and be familiar with the underlying
tools and technologies, which form part of the cloud service provisioning,
delivery and management.
