A Cloud Computing Revolution is Underway

Momentum Only Grows

Industry-wide, cloud computing has revolutionized the way enterprises manage, scale, and process large-scale applications, and derive value from data. The International Data Corporation (IDC) forecasts that the worldwide public cloud services and infrastructure spending will reach $1 trillion in 2024 at a compound annual growth rate (CAGR) of 15.7%.

Amid globalization and the growing demands of a remote workforce, companies of all sizes have now moved to cloud environments. Cloud technologies leverage a shared IT infrastructure and a reliable internet connection to enable users to manage multiple apps, solve workload challenges, and significantly reduce the company’s computing costs.

The elasticity of the cloud (the ease of growing or shrinking your platform-use as needs change) and its flexibility (on-demand availability, high efficiency, and advanced IT capabilities) means it is no longer seen as just an online data back-up server. Nothing short of a revolution is happening, now – cloud is ubiquitously accepted as a powerful and necessary tool required for a business to evolve and adapt.

Let’s take a deep dive into cloud computing, its advantages, and why you should consider embracing this paradigm shift.

What is Cloud Computing?

Cloud technology enables the reusability of IT resources for storing large databases, developing and hosting complex applications, and expanding computational power and other services on demand. Eliminating or reducing investments in large-scale infrastructure and software, coupled with the pay-per-use model, significantly reduces IT costs.

Here are some traditional computing techniques that have helped enterprises achieve additional computing and storage capabilities:

  • Cluster computing connects different computers in one location via LAN to work as a single computer, improving the combined performance of the organization.
  • Grid computing enables collaboration between enterprises to carry out distributed computing jobs using interconnected computers spread across multiple locations running independently.
  • Utility computing provides web services such as computing, storage space, and applications to users at a low cost through the virtualization of several backend servers.
  • Distributed computing landscapes connect ubiquitous networks and connected devices, enabling peer-to-peer computing. Examples of such cloud infrastructure are ATMs and intranets/workgroups.

History of Cloud Computing

  • 1950s
    The abstract idea of cloud computing developed when mainframe computers were primarily used to access applications and data residing on clients’ localized infrastructure.
  • 1960s
    We saw the birth of IT services coupled with a growing demand for personal computers using decentralized computing resources.
  • 1990s
    With the dot-com revolution, industries adopted dynamic client/server architectures with service providers’ offering virtual private networks.
  • 2000s
    The outsourcing of IT infrastructure management began when companies needed the capabilities to provide advanced server virtualization services via hosted cloud environments.
  • 2010s
    Cloud computing evolved to incorporate the delivery of cloud deployment models including infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).
  • Today
    Cloud collaboration — a hybrid collection of enterprise applications and virtualized social interaction tools — is offered as a service that allows multiple users to work together simultaneously on a particular task.

Who Uses the Cloud and Why?

Cloud’s evolving features are changing the way organizations of every type, size, and industry manage and process data. This includes everything from utilizing unlimited storage; adopting powerful analytics tools; updating applications and system infrastructure software; strategizing customer relationship management (CRM) and enterprise resource management (ERM); and migrating content and collaborative applications, as well as data management and delivery applications.

How Does Cloud Computing Work?

Cloud computing offers on-demand delivery of digital resources, allowing organizations and individuals the flexibility to eliminate or reduce legacy data applications and infrastructure. With pay-as-you-go cloud services, users only pay for their hardware and software consumption. With cloud computing, organizations are becoming more agile, reducing cost, innovating faster, and transforming their business goals and objectives with powerful analytics tools.

Types of cloud computing services

IaaS is a cloud computing model where virtualized infrastructure is offered to and managed for businesses by external cloud providers. With IaaS, companies can outsource for storage, servers, data center space, and cloud networking components connected through the internet, offering similar functionality as that of on-premises infrastructure.

Examples of IaaS are automated, policy-driven operations such as backup, recovery, monitoring, clustering, internal networking, and website hosting. The service provider is responsible for building the servers and storage, networking firewalls/ security, and the physical data center.

Key players offering IaaS are Amazon EC2, Microsoft Azure, Google Cloud Platform (GCP), GoGrid, Rackspace, DigitalOcean among others.


PaaS builds on IaaS. With PaaS, cloud vendors deliver cloud software and hardware infrastructure components like middleware and operating systems that are required to develop and test applications. The PaaS environment enables users to install and host data sets, development tools, and business analytics applications without the complexity of building and maintaining the infrastructure.

Key players offering PaaS are Bluemix, CloudBees, Salesforce.com, Google App Engine, Heroku, Amazon Web Services (AWS), Microsoft Azure, OpenShift, Oracle Cloud, and SAP.

Software as a Service (SaaS)

SaaS is unique in that it incorporates both IaaS and PaaS. With SaaS, the cloud service provider delivers the entire software suite as a pay-per-use model. SaaS allows users to easily access software applications such as emails via the internet.

The most well-known SaaS applications are Microsoft Office 360, AppDynamics, Adobe Creative Cloud, Google G Suite, Zoho, Salesforce, Marketo, Oracle CRM, Pardot Marketing Automation, and SAP Business ByDesign.

Public Cloud

The public cloud is the most economical option for users because the service provider bears the expenses of bandwidth and infrastructure. It has limited configurations, and the cost is determined by usage capacity. Despite the public cloud’s having high reliability, lower costs, zero maintenance, and on-demand scalability, it is not suitable for organizations operating with sensitive data and strict security regulations.

Private Cloud

The private cloud provides more control over customizability, scalability, and flexibility, all while improving security of assets and business operations. Private cloud infrastructure can be built on-premises or outsourced to a third-party service provider. Its main advantage over the public cloud is its ability to maintain the hardware and software environment over a private network exclusively for the owner. Large- and medium-scale financial enterprises, as well as government agencies, typically opt for private clouds.

Hybrid Cloud

Hybrid clouds are the combination of a private and public cloud. This provides more flexibility by allowing businesses to have control over critical operations and assets. The hybrid cloud architecture enables companies to manage private and public clouds through one portal and optimize workloads for each environment's strengths. For example, businesses can use the public cloud for running high-volume applications like emails and utilize private clouds for sensitive assets like financials, as well as data recovery – plus eliminating downtime during scheduled maintenance.

2. Accessibility

Cloud computing empowers enterprises to deploy their applications across the globe to provide service to their customers whenever and wherever it is needed. This allows customers to get an identical digital experience unhindered by geographic limitations.

3. Operational Agility

Businesses must have the ability to instantly scale their cloud capacity by accessing bandwidth demands from remote servers. If the business demand is increased, the enterprise can turn up its computing capacity and IT resources availability instantly. This resulting operational agility improves productivity, efficiency, and innovation, and it offers a competitive advantage and opportunity for disruption.

4. Reduced Expenditure

With the cloud, enterprises can focus on building their business rather than investing in hardware infrastructure and data centers that either remain idle or underutilized. As mentioned before, public cloud costs depend on consumption and remain a variable expense.

5. Automatic Updates/Patches

When enterprises deal with various software, operating systems, and applications from different vendors they require software and security updates to be performed on a regular basis. This can be a time-consuming process, and the downtime for system maintenance means loss of productivity. A cloud service provider or a managed service provider can take care of these automatically, saving time and manual effort on maintenance.
