Cloud Computing & It’s Growth

Cloud Computing

In the past few years, “Cloud” is the most frequently used term in IT Industry. Even, “Cloud and Cloud Computing” has become synonyms. This is because “Cloud Computing” or “Cloud Infrastructure” continues to grow at high pace. The fundamental paradigm to working with digital infrastructure has shifted from Builder to Consumption. IT Companies, which earlier were investing their resources in building the digital infrastructure, now they are investing in consumption. This is because digital infrastructure is already available in the form of Cloud.

According to the Cloud Computing Market Survey report, global size of Cloud Computing is already growing and expected to grow further at a CAGR of 18%. Cloud Computing market value will grow from USD 272 billion in 2018 to USD 623 billion in 2023. This also means, Jobs market in the Cloud Computing will also grow and even at faster pace.

According to a report by economic times, Indian Cloud Computing market is growing with annual growth rate of 30% and expected to breach USD 4 billion mark by 2020. India alone is expected to have more than 10 million job in cloud computing by 2022, with higher growth of salaries as well.

Along with it, there are many other surveys and reports, which also says almost similar about growth of Cloud Computing. To understand this rise of Cloud Computing, we need to know the answers to following questions:

  1. What is Cloud Computing(Cloud Infrastructure) ?
  2. What problems it solves (Benefits) ?
  3. Major Cloud Computing providers ?

What is Cloud Computing

Cloud Computing or Cloud Infrastructure is the availability of IT resources that can be accessed globally through internet. IT resources may include compute servers, data storage, databases, networking, software, analytics, and intelligence etc. Mostly these resources are provided as a servicewhile physical hardware resources are owned by service provider. Services are consumed based on need& costs are paid accordingly.

To enable Cloud Computing services, service providers create their gigantic farms of installed physical machines (racks of servers), connecting networks to them, install software. Then they create their service APIs for the use of their infrastructure. 

Benefits of Cloud Computing

Cloud Computing has made paradigm shift for digital enterprises from “Building Infrastructure” to “Consuming Infrastructure”. Enterprises are now focusing on Consumption of compute resources instead of building them. There are many benefits that Cloud Computing provides:


Agility is the ability to adapt changes rapidly and cost efficiently. In competitive business world, agility is important factor for the success of a business.

Cloud Computing provides broad range of technologies, that can be used immediately on demand. This helps to faster innovation & developmentand enables to build anything. It enables businesses to adapt rapidly to the changed market scenarios, can change their strategies, develop their products& analysisfaster. Businesses does not need to worry about compute infrastructure.


Elasticity is the ability to increase or decreasein resources according to the requirement. Cloud Computing provides this flexibility of elasticity.

Any business product usage is not constant all the time. For ex. An e-commerce company sale may increase in holiday time and can be less in other days. Accordingly, the digital traffic to their website (application) may increase or decrease. Based on digital traffic, demand for compute resource may increase or decrease.

Cloud Computing provides inbuilt auto-scaling functionality, to increase or decrease the computing power according to the demand. With this business don’t have to decide for compute requirement beforehand. This helps businesses not to worry about wastage of resources (if, more resources beforehand) or bad experience to their customers (if, less resources beforehand)


With Cloud Computing, business can use resources on demand & as per their requirement andshould pay according to their usage.

Businesses do not have to invest capital in buying hardware & software. Neither,shouldset up &run on-site datacenters. Cloud allows to trade capital expense for variable expense with “pay as you go” model. Business can pay only for they have already used.

Global Scale

Cloud Computing provide global outreach. Service providers have already setup their datacenters at multiple locations worldwide. Business can setup their servers in any location provided by the service provider.

For ex. To provide better application experience to their customers, business can setup their servers near to their customers geo location. Business can also choose and use Content Delivery Networks (CDNs).


Setting up and maintaining data center is time consuming IT management. Cloud service providers has the responsibility to maintain their data centers. They maintain their data center with latest software patches, security installations etc.

Cloud Computing comes with shared responsibility. With Cloud Computing business does not have to setup their own data centers. Business can focus on their core areas (products), security of their product only. As a result increasing their productivity and efficiency.


Hardware technologies are changing faster, making underlying hardware to perform faster with minimum response time.Like hard disks of different varieties HDD, SDD.Cloud service providers upgrades their datacenter hardware regularly to the latest generation of fast and efficient computing hardware.

Business has the option to choose their compute hardware as per their requirement. Performance critical application can be run with best underlying hardware in place.


Cloud Computing provides data backups & disaster recovery available at multiple locations. One application running on one location can be taken easily on another location.

Data backups and Disaster recovery provides confidence & business continuity. Applications can be mirrored at multiple location on service providers network.


Cloud Computing provides security at its core, with broad set of policies, technologies and controls. Protection of datacenter, underlying hardware and software is providers responsibility. Providers install updated security software and firewalls to secure infrastructure from new threats.

Service providers follows shared responsibility principle. Business should provide security settings for their applications and their connected services only. Business don’t have to worry about new threats and security updates.
