True Sense of
When it comes to private cloud implementations in the enterprise
space, the interpretation itself is the biggest issue
Technology has long matured to help build and take full
benefits of private cloud but the adoption has been rather
slow. Market figures may claim differently, but these are of
broader sense, to say the most.
According to reports done by leading analyst firms on
enterprise technologies global private cloud adoption figures
claim to be over 30% with over 20% claiming to be moving
rather fast on the build-out. A deeper look at these reports will
reveal - the fine print is where the reality of the true adoption of
private clouds is stated. The very definition of Private Cloud is
skewed in most cases - and in most of the mentioned 30%
cases the key features of private cloud such as metered usage,
multi-tenancy, etc. are clearly missing.
When it comes to private cloud implementations in the
enterprise space, the interpretation itself is the biggest
Virtualization Vs. Private Cloud
The most mistaken technology set is right here.
Virtualization often gets confused with private cloud. The
fact is that virtualization is only a component of cloud Private or Public.
The intent of virtualization is to increase utilization of many
servers for a particular workload. Whereas private cloud is a
whole different ballgame when it comes to increasing
utilization of IT resources. It leverages multi-tenancy to
differentiates workloads into 'tenants' that are used at
different times allowing one to consolidate utilization of all IT
resources across the data center - meaning very high
utilization of existing resources.
True Sense of Private Cloud
Virtualization solution is implemented to provision
infrastructure faster and consolidate servers - done by using
a hypervisor and set of management tools. The
management software provisions Virtual Machines (VMs)
where OSes can be installed and workloads can be run and depending on the workload that has to be run,
compute, storage, network access needed are provisioned
accordingly. Orchestration software is used for provisioning,
and the virtualized infrastructure is connected to the local
network that manages the VMs.
Private Cloud is a totally different scenario although
virtualization forms the basis of all cloud buildout. The key
five characteristics of a private cloud are:
Broad Network access
Measured or Metered Usage
Cloud should be viewed as API through which you can
control capacity and provisioning of resources, such that
you can automatically move workloads.
Now, visualize a scenario of a centralized IT department of
a large organization that supports several branches and
departments that have specific IT requirements at various
times. In order to provide better support for their branch
offices and various departments without hiring more staff,
increase turnaround time when provisioning service for
applications, they virtualize the IT environment and deploy
management tools in a way that applications and OSes are
preinstalled in disk images.
Depending on access levels, users can now performs tasks
such as launch and install VMs from supported images. A
branch or a department wanting to try out a new application
or a tool can now provision a new server (read VM), install
the application and use the same for a period of time
specified during provisioning.
This rapid turnaround without having to put in capital budget
for new servers and ability to turn on and off services (read
servers in this case) is really the true sense of a private cloud
- the IT department is using virtualization, but they have
added a layer of self service for branches/departments (Ondemand Self-service) that can access services over a local
network or a virtual private network (VPN) over the Internet
or a web-based interface (Broad Network Access). The
users depending on access can provision IT resources
quickly and turn the same off also as fast (Rapid Elasticity)
with little help from the IT department and without having to
go through the process of raising a capital expenditure for
the resource. IT department can meter actual usage for
each of the service or provisioned resource by the branch or
department and charge back on an actual usage basis
(Metered Usage/ Measured Service).
The Mid-market and SME Perspectives
The model defined still has limitations for some of the midmarket organizations and most SMEs, especially in the
Indian scenarios. Proprietary hypervisors and management
tools that are needed to buildout a private cloud is still
expensive for organizations with limited budget to innovate
to do more. Furthermore this also requires bringing in a slew
of new hires with skillset to implement and manage.
implementers, there are a bunch of low-cost, open source
platforms that are more suited to the budget-strapped
Here the important matter for organizations to consider is
their goals in building a private cloud.What an organization
wants from a private cloud depends on what business they
are in; one size fits all strategy may not work here. Providers
of hosting and managed services as well as cloud service
providers can help assess and identify the size and shape
that fits these organizations.
