The gap between Cloud and On-premise is definitely blurring with Cloud services making a strong business case. Learn more about the many benefits and advantages of both services.

1. A business case for deploying your solution on Cloud if you're looking for flexibility of
minimal investments, quick commencement of Web & Mobile App, choice of tenure, ability
to migrate as and when required, ability to integrate and many more such advantages.

2. ON-PREMISE VS CLOUD SERVER
On-Premise – Advantages Cloud Servers – Advantages
1. On-premises can be an ideal solution for those who
only want an initial investment (CAPAX) for the
system set-up.
2. Can be cheaper on longer run.
3. Maintenance costs can be kept to a minimum if
scaling your business isn’t the goal.
4. No third party access to the data
5. Physical control over the data
6. There’s no need for an internet connection to access
the data, if it is within same physical network
7. Physical control over your back-up system
8. If solution architecture is designed with horizontal
scaling facility then it is possible to scale-up with less
efforts
1. Lower cost of ownership and comes under the OPEX
2. Comparatively low IT maintenance costs
3. Off site data storage
4. Productivity from anywhere, personal presence is not
required
5. Almost all the vendors provides 99.99% uptime
6. Disaster recovery assistance and auto backup
functions
7. Easily upgrade or downgrade (Scale-up/Scale-down)

3. Areas that vary depending on which solution
you deploy include:
Costs
Security
Agility and Scalability
Maintenance
Backup & Disaster Recovery

4. ON-PREMISE VS CLOUD SERVER
On-Premise – Cost Cloud Servers – Cost
High Capital expense costs
1. Hardware
2. Storage/Space
3. Power
4. Cooling
5. Disaster recovery
6. IT Team (Highly skilled)
7. Maintenance
8. Training
On-Going Cost
1. Upgrade dependent applications and licenses
2. IT Team cost as it requires more number of persons
along with higher skills comparing the Cloud servers
Advantage
Can be slight cost efficient in a long run, if scale-
up/scale-down is not required
Low Capital expense cost
1. Subscription Fee
2. IT Team is lean
On-Going Cost
1. Subscription Fee
2. IT team cost with less number of people
Advantage
1. Predictable subscription pricings
2. Costs allocated to OPEX
3. No upfront hardware/software cost

5. ON-PREMISE VS CLOUD SERVER
On-Premise – Security Cloud Servers – Security
Customizable
Security can be highly customizable to organization’s
processes, requirements and regulatory compliances.
Disadvantages
Whether due to inexperience or insufficient practices in
proper security protocols, it stands to reason that critical
information is at risk no matter where it is stored. Due to
which it requires dedicated & knowledgeable resources. So,
if you do cloud vs on-premise cost comparison, add the cost
of a robust security system to protect your infrastructure.
Advantage
No third party access to the data.
Highly-secure data encryption is essential for any online
business and with cloud computing, it’s all included in the
package. Data is secured and backed-up at regular
intervals, allowing for access to information as and when
needed.
Disadvantage
Though most vendors are rigorous with their security
practices and follow the global regulatory standards, it
takes a leap of faith to place that information in someone
else’s hands. Cloud servers is aggressively targeted by
hackers.
Advantage
By purchasing additional data security package, it can
deliver superior data security.

6. ON-PREMISE VS CLOUD SERVER
On-Premise – Agility and Scalability Cloud Servers – Agility and Scalability
Advantages
As team has physical control over the hardware means
upgrades can be tightly controlled.
Disadvantage
Planning in advance is a key part while changes are required.
It requires time, thorough research, purchase and deploy
hardware.
Pre-requisite software licenses (e.g. Microsoft server, SQL
server etc.) must be procured separately and needs to be
managed manually.
Its tricky and lengthy process to downsize the physical
servers, it’s possible if the deployed application is designed
with horizontal scaling facility.
Advantages
Pay as you use. Cloud resources can be rapidly adjusted
to accommodate specific demand.
Disadvantage
Costs may increased if the cloud infrastructure is not
properly managed.
Few of the cloud providers (e.g. MS Azure) provides
platform as a services in which business doesn’t need to
procure additional pre-requisite software licenses.
Easily scale up the infrastructure during the Pick Time of
the usage and scale down during the low usage. In which
instances can be upscaled and downscaled as per the
requirements.

7. ON-PREMISE VS CLOUD SERVER
On-Premise – Maintenance Cloud Servers – Maintenance
On-premise deployment is susceptible to hardware
failures that may result in downtime of all hosted
solutions. Hence, the IT Team has to perform an
additional task of preventive maintenance and keep
hardware backup as a failsafe.
On-premise network and hardware performance
requires to be monitored & managed on regular
intervals that usually requires a dedicated resource
(network engineers, etc.)
Upgradation of all the installed pre-requisite software
(security patches, IIS updates, etc.) needs to be
managed by the IT Team.
Most cloud vendors provide 99.99% uptime guarantee,
so the business (tenants) doesn’t need to be concerned
about the hardware failures.
No need to monitor & manage the network and
hardware performance by the business (tenants) as it is
the cloud vendor’s responsibility to maintain their uptime
and comply to the performance guarantee.
Cloud vendor manages the upgradation for all its tenants.
So, the business doesn’t need to invest any time-efforts.
Business always gets upgraded/latest versions of all the
pre-requisite software.

8. ON-PREMISE VS CLOUD SERVER
On-Premise – Backup & Disaster Recovery Cloud Servers – Backup & Disaster Recovery
Disaster Recovery and regularly scheduled backup plans
are a necessity. With on-premises deployment, this
must architected and implemented by specialized
personal from IT Team.
Backup and disaster recovery is scalable to the growth of
the business and only pay what you use.
Backing up to the cloud can happen as often as every 15
mins.
Additional services of Disaster Recovery and backup can
be availed through cloud vendors directly. Easily connect
to cloud from anywhere, using any devices.
