In recent years the phrases “cloud computing”, “the cloud” or just “cloud” has become quite ubiquitous in the ever-growing ICT ecosystem. This was made even more popular when Amazon burst onto the scene with its Elastic Compute Cloud product in 2006, however this was not where the journey began. As far back as 1993, the term cloud was used to refer to platforms of distributed computing.
To understand the difference between public cloud, private cloud, and hybrid cloud we have to first lay bare the characteristics these types of cloud technologies possess.
Public Cloud – Public cloud services typically adopt a multi-tenancy method of delivering software services to their users. The computing resources are used by more than one business or organization and the infrastructure is managed by a third-party service provider that has the manpower and expertise to manage the multiple data centers used. This type of cloud technology is the most popular and is ideal for small to medium sized businesses, because of the relatively cheap implementation and overhead costs.
These days cloud technology is the backbone of the burgeoning IT industry, ranging from IaaS (infrastructure as a service) to advanced AI and Machine Learning services. There are many players in this space, some catering to niche markets and needs, the three biggest players however are Amazon Web Services (AWS), Microsoft Azure, and Google’s GCP.
Private Cloud – This is a single tenant system. This simply means the computing resources are used exclusively by one business or organization, the private cloud can be physically located at the organization’s datacenter or hosted by a third-party provider. This is typically used for proprietary software only used within the business or highly customized instances of other Public Cloud products. This is used by large enterprises and cost significantly more to implement and sustain.
Hybrid Cloud – As the name implies combines both on-premises (private cloud) infrastructure with third-party resources (public cloud), allowing flow of data between the two. A typical use case for this are manufacturing plants where the few extra seconds taken to communicate with distant third-party infrastructure can make a difference in production efficiency. This is also capital intensive, but most times not as expensive as investing in the full-scale data center technology. This type of technology is used by medium to large scale enterprises.
To determine the right cloud service fit for your business, there are two major factors to consider; your budget and your use case. For example, if you work for a large enterprise with sensitive data managed by a proprietary software system, the best cloud solution to recommend would be a private cloud service with adequate redundancy in the case of a system failure. On the other hand, public cloud service is the cheapest of the lot and is consumed by a greater percentage of users including large enterprises, ergo if you do not really deal with very sensitive data, and you are looking to drastically cut down on expenses, public cloud is your go-to. Hybrid cloud balances the best of both worlds to cater to unique needs by organizations this is also used by medium to large enterprises looking to optimize their systems.
