What is Cloud Computing?

Cloud computing has established itself as the new normal for the current business environment. It is one of the important innovations in the digital business landscape; however, it is often misunderstood and underutilized.

More than $1.3 trillion in IT spending will be affected by the shift to the cloud by 2022.

What exactly is the cloud? Who owns the cloud? How did the cloud start?

These are some common questions around the cloud that you have probably heard. So what is cloud computing?

Cloud Computing History

Cloud computing is not a modern technology. It has continued to evolve since the early 1950s. In 1955, John McCarthy created a time-sharing concept, enabling a group of users to use an expensive mainframe simultaneously. McCarthy’s theory of mainframe timesharing is said to have had a significant impact on the development of the internet.

With the evolution of technology, the concept of cloud computing took a giant leap in the mid-1960s, when an American computer scientist Joseph Carl Robnett Licklider described a theory of interconnected computing systems. This idea gave birth to the predecessor of the internet: ARPANET (Advanced Research Projects Agency Network).

Licklider’s contribution is considered to be the most valuable in the creation of cloud computation; thus, he is believed to be the father of cloud computing.

Cloud computing history

From the 1970s to the 1990s, cloud evolved at break-neck speed because of advancements in technology. In 1972, IBM released VM (Virtual Machine) operating system, exhibiting the behavior of dedicated hardware, giving users the same experience on a virtual machine. In the 1990s, telecommunications companies started offering “Virtualized” Private Networks (VPNs) as rentable services.

Professor Ramnath Chellapa of Emory University, in the year 1997, defined cloud computing as:

Cloud computing first definition

As businesses started gaining a better understanding of the term cloud, it gained popularity, and in 1999, Salesforce emerged as an ideal example of successful cloud computing adoption.

However, the term cloud computing became extremely popular in 2006 when Amazon released its Elastic Compute Cloud product.

Benefits of Cloud Computing

The rate at which data is exploding has pushed the digital businesses to embrace cloud computing as the platform for innovation. Businesses across all the industries are leveraging cloud solutions for various use cases, like digital security, disaster recovery, big data analytics, and data backup.

37.3% of organizations believe ‘digital security’ is the biggest challenge that they face on the road to digital transformation. – Net Solutions’ Digital Transformation 2020 Survey

Today, cloud solutions help businesses navigate the challenges of the digital era, enabling them to respond to a complex and fast-paced business landscape quickly. Adopting the cloud allows businesses to run more effectively, serve customers better, and boost their revenue: companies that invest in cloud, big data, and mobility see a 53% faster revenue growth than their competitors.

Apart from helping businesses transform, differentiate, and gain a competitive advantage, the benefits of cloud computing are:

  • Cost Optimization
  • Scalability
  • Security
  • Efficiency
  • Automatic Upgrades
  • Disaster Recovery
  • Mobility

Types of Cloud Deployment: Public vs Private vs Hybrid Cloud

A single type of cloud computing is not fit for every business requirement. There are different cloud deployment models and services, which have evolved with time to offer the right solution for every disparate business needs. Thus, before going into the process of cloud migration, it is essential to determine the types of cloud deployment — Public Cloud, Private Cloud, and Hybrid Cloud.

Public vs Private vs Hybrid Cloud

1. Public Cloud

Public clouds are operated and owned by third-party providers. In the case of a public cloud, the services offered by cloud providers are over a network that is open for public use, implying that an organization shares the same hardware and network devices with other companies of the same cloud service provider. Microsoft Azure is an example of a public cloud.

2. Private Cloud

A private cloud is a cloud deployment model that is exclusively used by a single organization. In the case of a private cloud, the services and infrastructure are maintained on a private network, which is either located physically at the organization’s on-site data center or are hosted by third-party service providers.

3. Hybrid Cloud

The combination of private and public clouds gives rise to a hybrid cloud, allowing the sharing of data and applications between both of them. Using a hybrid cloud deployment model enables businesses to move applications and data between public and private clouds, leading to an agile, secure, and flexible digital business model.

Types of Cloud Services: IaaS vs SaaS vs PaaS

IaaS, PaaS, and SaaS are the types of cloud services that help businesses transform their digital experience while reducing the infrastructural costs in turn. All these cloud services differ mostly in what they offer to the end-user. Each of these cloud services has its benefits depending upon the business and functional requirements.

Here is a breakdown of the different cloud services: Iaas vs PaaS vs SaaS.

1. Software as a Service (SaaS)

SaaS/ software as a service refers to cloud based applications, often developed by a SaaS development company, that are hosted online by a company that makes it available for purchase on a pay-as-you-go pricing model.

73% of organizations state that almost all of their apps will be SaaS-powered by 2020.

Key Reasons Businesses Should Adopt SaaS Business Model

Adopting a SaaS Business model provides many benefits over traditional on-premise software installations. Some of them are as follows:

  • Speed of Innovation
  • Reduced Marketing Efforts
  • Faster Time to Market
  • Reduced Churn Rates
  • The Anytime, Anywhere Model

2. Platform as a Service (PaaS)

PaaS/ platform as a service refers to a cloud based platform service that offers a robust framework for developers to build, test, and manage new custom applications. Unlike SaaS, it does not provide software over the Internet; instead, it offers the platform to businesses where the software is being built. Google App Engine and OpenShift are common PaaS examples.

58% of those enterprises that have invested in Platform-as-a-Service (PaaS) expect a positive ROI in less than three months.

3. Infrastructure as a Service (IaaS)

IaaS/ infrastructure as a service refers to a cloud based infrastructure service that offers virtual data centers to businesses, which help them build and manage their operating systems, servers, data storage, and network infrastructure. The common IaaS examples are Microsoft Azure and Amazon Web Services (AWS).

IaaS is the fastest-growing cloud spending service with a five-year CAGR of 33.7%.

Cloud Computing Platforms: AWS vs Azure vs Google Cloud

The cloud computing market is flooded with a number of cloud computing platforms; however, Amazon (AWS), Microsoft (Azure), and Google (Cloud) stand out as three leaders, according to their market share and Gartner’s Magic Quadrant report.

Gartner Magic Quadrant Report places AWS, Azure, and Google Cloud as IaaS leaders

So, how do you decide which cloud computing platform to choose? Here is a breakdown of the different cloud computing platforms: AWS vs Azure vs Google Cloud

Cloud Strategy

Cloud is a buzzword, but a staggering 37% of cloud migrations fail. Big brands like Twitter and Pinterest have experienced a cloud migration failure. Even the UK-based bank TSB witnessed a cloud migration fiasco, forcing them to increase interest payments to cover customer losses. So why do cloud migrations fail?

Good tactics can save even the worst strategy. Bad tactics will destroy even the best strategy. – General George S. Patton Jr.

One of the key reasons for cloud migration failure is the business’s inability to frame out a cloud strategy before embarking on a cloud migration journey. There are a few necessary steps that every enterprise cloud strategy should follow.

  • Creating an Enterprise Cloud Strategy Team
  • Analyzing Applications Thoroughly
  • Building A Hybrid Cloud Strategy Roadmap
  • Reskilling and Upskilling
  • Implementation
