Just over 2 decades ago, the internet was a fringe utility, often misunderstood & frequently disregarded. The turn of the century gave way to digitalization & technological innovation, the likes of which weren’t expected for years to come.
Herein lies the irony!
The internet has irrefutably been the backbone & primary driving force behind this massive global transformation. It has connected millions across continents, expedited mass development & exponentially broadened the horizons of learning & education.
As is becoming increasingly common in today’s day & age, a new chapter beckons.
Cloud Computing has taken the world by storm & the opportunities of its application seem endless.
But what is the cloud? And how does cloud computing actually work?
Let’s delve deeper into a novel idea is progressively revolutionizing workflows as we know it.
Grasping the concept of ‘Cloud’ & Understanding Cloud Computing
Cloud computing is simply the process of running different IT applications by utilizing the internet. It can also be defined as the delivery of varied services, tools & resources over the internet. These can include data storage systems, networking channels, software & servers. The key aspect is to realize that neither the ‘cloud’ nor ‘cloud computing’ are actual technologies but only terms for the internet & processes facilitated by the use of the internet, respectively.
To put it in layman’s terms:
- If you have set up any IT system which is accessible by other computer or electronic devices, provides the user a certain utility & is scalable on demand, you’ve successfully created a cloud.
Varieties of Clouds
No two cloud entities are designed the same with definite tweaks in their essence of operation. Similarly, end-users of cloud services each have a unique requirement & hence their choice will also be different from each other. Keeping this mind, 3 overall types of clouds exist as follows:
- Public Clouds
– Instances where the infrastructure & software environment is owned &
stored by a third-party organization and is essentially rented on demand is
known as a public cloud service. All clouds whose physical & digital
bandwidth is divided & shared by multiple end-users become public clouds.
Some key examples would be Amazon Web Services (AWS), Google Cloud, Microsoft
Azure & Apple iCloud.
- Private Clouds
– Cloud environments solely operated by a single user, company or organization
are called private clouds. The infrastructure required (servers, storage etc.)
can be stored on-site at the offices of a company or can sometimes be
outsourced to a third-party to host on their behalf at an agreed upon cost.
Therefore, all services utilized on a private cloud are done so on a secure,
- Hybrid Clouds
– In cases where applications and services seamlessly move through multiple
cloud environments which can be a combination of 2 or more public or private
clouds or a mixture of both, can be referred to as a hybrid cloud. This allows
for maximum flexibility, efficiency and optimization of workload for end-users.
Major Types of Cloud Services
All in all, 3 distinct cloud service models exist which are being widely adopted around the globe.
- IaaS or Infrastructure as a Service – The most commonly utilized cloud deployment
model in which companies essentially lease hardware & IT equipment such as
physical servers, data storage drives, networks, virtual machines from cloud
providers for a certain fee. The end-user accesses this infrastructure through
a digital application framework over the internet while the cloud provider is
responsible for the maintenance and upkeep of the rented hardware &
- PaaS or Platform as a Service – Quite commonly harnessed by developers &
programmers. PaaS defines a cloud model wherein the physical infrastructure as
well as the software environment (the platform), required to develop, design,
create & run various applications is hosted by a third party and accessed
by an end user/s. It’s effectively used when a company does not want the headache
of managing the physical infrastructure or software platform but focus on
actually creating other applications.
- SaaS or Software as a Service –The most easily understood of the 3, SaaS refers to the instance when a functioning software is provided over the internet, generally on a subscription basis. Most mobile apps fall under this umbrella. A well-known example would be Microsoft Office 365 which is licensed by billions of people for a nominal fee.
- The most obvious benefit is the reduction in expenses, as we only pay for the application & type of service we require while the lack of maintenance of physical equipment or hardware cuts down on unnecessary costs.
- Scalability – The exact amount of IT resources can be provided at the required time to the right place.
- Speed & Performance – Cloud services are outsourced to dedicated servers worldwide while only the essential required applications are utilized on demand, providing immense speed of operation.
- As data stored on the cloud can be replicated at multiple unique & separate locations, it provides redundancy of storage in case of major crashes or calamities.
Downsides to Using Cloud Services:
The only possible glaring downside to ‘harnessing the power of the cloud’ is the security risk.
With information stored on external, third-party servers, there lies an inherent risk to permanent loss off sensitive & confidential data. With cybersecurity measures developing to safeguard information in better ways, no security system is foolproof and can be breached.
