Cloud Computing Vs. Traditional Computing
Cost Efficiency
Traditional computing directly
relates to traditional IT infrastructure, which will involve computing devices
with processors and cache memory, and data storage integrated into the devices,
portable or located at a different location, functionality, and data provider
resources named “servers,” etc. The hardware cost is comparatively much larger
to cloud-based computing services, as all functions of data processing, image
or video processing, functions, laying out paths in the information highway are
all done locally, and every capacity that is today vested with cloud had to be
made available on the machines or at the local sites.
Cloud-based hardware costs will
include the cost of installing and improvising switches, hubs, routers,
servers, data storage, processors, which will be managed by the service
providers. The end-users will gain access to their data through web
browser-based platforms or software applications, and they need only to have
devices with sufficient capacity to support these platforms.
Architecture
Upgrading and upscaling the
capacity and functionality of such systems too had to be taken care of by the
users. These may be individuals or corporations. Software updates, IT, and
cybersecurity too were frequent concerns of the localities who have these
systems installed to use.
Cloud-based applications are made
for their own infrastructure with automation. The upgrading and upscaling are
usually managed before the deployment of the application. Automation is a key
difference between the two versions.
Traditional architecture relates
applications with three tiers: database tier, presentation tier, and the
application logic tier Cloud-based applications will work on the interface and
system automation.
Infrastructure
Traditional applications have a
static infrastructure - data has to be scaled manually.
Cloud-based applications will
process data with automation, and the end-user only needs to input the
requirements using keywords.
Operating System Dependency
Traditional Applications will 100%
depend on the functionalities, capabilities, and sophistication levels of the
operating systems they are deployed in. Since, in turn, the Operating system
will depend on the hardware of the device it is running on, the traditional
computing applications, too, will have a heavy dependence on the nature of
their machines.
Cloud-based applications will have
minimum dependence on the operating systems while having omnipresence as a key
feature in the technology.
Automation
One of the key features of the two
methods of computing is automation.
Traditional computing will have to
have in-house care for all machinery and hardware, maintenance, upkeep, with
trained professionals at the site.
Cloud computing will ensure that the
end-user will be given all these services (maintenance, renewal, care, security
). The end-user will only have to mind about the usage.
Security
Traditional computing will require
the end-user to manage security locally. Most applications used will have only
one layer of security and one storage device or destination. Anyone who can
gain LAN, Network, or Physical access to these devices will make the end-user
vulnerable. The solitary security layer will also require constant upgrading
because it will become obsolete frequently in the face of threats targeting a
small number of hosts.
Cloud computing will have several
layers of security for the data and several separate and sometimes independent
locations to house the data. This makes them far less vulnerable to attacks,
and the multi-layered security will ensure that developing an attack mechanism
is extremely difficult.
Availability and elasticity of the service
Traditional computing will have
applications that will have the same functions and features for a long time.
The updates will be released with long intervals between them.
Traditional applications will also
be available only on the respective devices they are installed on. If the
device experiences hardware or major software failure, and the end-user is
compelled to move to another device, they will not be able to work with the
application.
Cloud computing will have
applications that will be regularly updated by the hosting companies, in most
scenarios free of charge.
The services offered by these
applications have much higher elasticity. They can be accessed through multiple
devices and will only require signing in credentials and identification to
operate the same way from any number of new devices.
Backup and Data Recovery
Backing up the stored data in
traditional computing will require data stored locally and the backing up
process to be executed manually or programmed manually every time.
Any chance of recovery in lost data
will also be depending on the talents and recovery tools used by the end-user
or their teams.
In cloud-based computing,
automation will take care of the backing up process, with the backup storage
supplied by them. Recovery will also be based on the agreement between the
service provider and the end-user, as mentioned when such service was obtained.
