Cloud computing: Why should businesses do it in 2021?

The recent digital transformation, which continues to gain momentum, would not be possible without cloud computing for business. Since the beginning of the pandemic, business leaders have had to quickly adapt to a new work reality involving teleworking and systems dedicated to online communications. For many companies, remote work has become a crucial model to reduce the impact on productivity. 

Highly functional and cost-effective, cloud computing is increasingly becoming the best data storage solution for businesses. There are numerous benefits of using cloud-based solutions: increased data security, automatic software updates, no server space required, to name but a few. 

What is Cloud Computing?

Cloud Computing is an on-demand model – provided as a service by another company through pay-as-you-go pricing – that utilizes servers and makes them available remotely to users via the internet (“the cloud”). In other words, it’s your own private and secure computer, in a room full of computers, that is personalized according to your needs. As a bonus, you pay for just the speed and storage necessary. 

There are three main types of cloud computing service models in business:

Infrastructure as a Service (IaaS)

IaaS is a model where infrastructures (servers and storage) are rented in the cloud and delivered on-demand by a third-party service provider. This service allows IT departments to save the time and money it would require building an in-house data centre.

Platform as a Service (PaaS)

PaaS is a model where a platform is provided for software creation via the internet. This service allows developers to design applications without the complexity of maintaining the software/infrastructure.   

Software as a Service (SaaS)

SaaS (or cloud application service) is a software distribution model hosted by a third-party service provider and available remotely via the internet. Most SaaS applications do not require any installation as they run through a web browser. 

How cloud computing can help businesses

There are several reasons why companies and IT service providers are moving towards the cloud. Here are some highlights of cloud computing for businesses:

1. Data Security

Long considered a concern for businesses, the security factor is now seen as a strong point of the cloud-computing solution. Here are a few advantages of cloud computing from a security point of view:

  • World-class technology
  • Complex security protocols
  • Cybercrime prevention
  • Data loss prevention (natural disasters such as fire or flood, hardware failure, etc.)
  • Control over sensitive data
  • No backup strategy needed

2. Cost Efficiency

Cloud computing helps businesses save money, time, and resources in many ways:

  • Lower infrastructure costs 
  • Less downtime
  • Fast implementation
  • Businesses only pay for services and features they need
  • Possible to scale up or down depending on the business situation (less storage space needed, remove users, etc.)

3. Scalability 

With the Pay-as-you-go cloud computing system, businesses pay only for the data storage space and the features they need. As businesses grow, cloud technology allows them to scale their computing solutions according to their needs. It is now easier, faster, and less expensive to add or remove data space storage. 

4. Improved Productivity and Flexibility

Not only does cloud computing allow to focus on business rather than infrastructures, but it also lets employees access the same data at once, from any location and from any device.  Thanks to cloud technologies, it is easier than ever to access and share business information with colleagues and customers. 

5. Reduced Carbon Footprint

The cloud allows to eliminate large on-premise computing systems and servers requiring 24/7 electricity. 

Cloud computing for better customer experience

Having business data stored in the cloud has several advantages for the customer experience

  • Cloud data storage allows you to analyze and understand the types of customers and their consumption habits to have a more personalized approach with them.
  • Data centralization allows multiple employees from different departments to access customer information in real time, quickly and from any location. A great team collaboration contributes to a positive customer experience.
  • For certain types of businesses, cloud computing allows customers to access information through a self-service application. Being able to access information quickly from anywhere and anytime helps improve customer experience.

The Weather Company, for example, relies on cloud computing to store fast changing weather data and propel it through different channels and locations. They provide information every day to millions of users internationally. As customers, we expect to have access to weather forecasts anywhere and quickly, which is made possible with cloud computing.

ROI and payback period of cloud computing

As mentioned above, companies now have several good reasons to migrate technological activities to a cloud environment versus investing in on-premise systems. Especially since remote work has become a common reality with the pandemic. 

However, every new IT project investment needs to be justified by showing that it eventually pays for itself. So, what is the average payback period of a cloud computing migration? The cashflow will most likely be negative the first year as you must pay for the migration costs. In 3-5 years, you will notice a significant increase in cashflow which justifies the positive return on your investment.

There is a serious opportunity to provide important ROI when adopting a well-thought-of cloud migration strategy.

How to estimate cloud engineering ROI and payback period:

STEP 1 – Identify all costs related to the current servers that you will no longer need to pay after a migration to the cloud (total cost of ownership). These costs include replacement or repair of on-premise servers, licences, electricity, maintenance and support, physical space, etc. This amount will give you the annual saving cost.

STEP 2 – Identify all costs related to the migration: cloud subscription, consultant hours, internal hours, etc. This amount will give you the investment cost.

STEP 3 – Calculate the ROI 

(annual cost savings – investment costs) / (investment costs) = ROI

Annual cost savings = 50K

Investment costs for cloud computing migration = 70K

Year 1: (50K – 70K) / 50K = – 40%

Year 3: (50K*3 – 70K) / 50K = 160%

Year 5: (50K*5 – 70K) / 50K = 360%

STEP 4 – Calculate the payback period

(investment costs) / (annual cost savings) = PAYBACK PERIOD

Annual cost savings = 50K

Investment costs for cloud computing migration = 70K

investment (70K) /annual savings (50K) = 1.4 years (payback period)

Choosing to migrate your business data towards the cloud makes sense from a performance-oriented and strategic point of view. Especially with the COVID-19 that causes many employees to work remotely. The choice of provider is entirely up to you, but it is important to do some research to choose the one that best suits your business needs in terms of cost, level of performance and flexibility.
