Today, businesses across the globe are facing unprecedented challenges as they seek to stay on par with the increasing demands from customers and shareholders. To navigate through these challenges and to keep a check on increasing IT costs, CIOs from leading corporations are betting big on cloud technologies for building new IT ecosystems to drive business agility and cost savings.
What is cloud computing?
Cloud computing provides enterprises flexible and elastic IT-related capabilities such as software, infrastructure, and hosting in a pay-as-you-go model. Cloud solutions help organizations achieve a transformational shift of their IT operations from a capital expenditure to an operating expenditure for more predictable spending. Enterprises can leverage capacity on demand with the flexibility to scale up and down as needed, and don't have to pay for underutilized capacity.
Let's take a closer look at cloud computing with a simple example. Google's mail service enables users access to their email from anywhere via the Internet. Google provides the email interface and storage space required to host user data. Users can log in and access their email from any device at any time. This convenience of access drives high levels of customer satisfaction in their user experience.
What does this really mean for businesses?
A flexible pay-as-you-use model for managing key IT operations empowers businesses with the ability to scale up their IT infrastructure per business requirements and gain more control on IT expenditure. The advantages of cloud adoption cannot be limited to just IT transformation; cloud has the power to impact all aspects of the business, helping drive innovation and speed. Cloud technologies act as a foundational base for companies who aim to achieve digital transformation and create better customer experiences online.
Some interesting cloud computing projections
- According to the 2018 IDG Cloud Computing Study, cloud computing is projected to increase from $67B in 2015 to $162B in 2020 at a compound annual growth rate (CAGR) of 19%.
- Gartner predicts by 2020, Cloud spend will grow at 6X the rate of IT spends.1
- The 2018 IDG Cloud Computing Study also reveals that 77% (population size of 550 companies) of enterprises have at least one application, or a portion of their enterprise computing infrastructure, in the cloud.
Popular cloud delivery models
|Traditional IT Ops||Cloud IT|
|Data servers and storage||IaaS|
|Applications that have direct business impact||SaaS|
|Applications that have no direct impact on business (supports enterprise applications)||PaaS|
- Infrastructure-as-a-Service (IaaS) is a cloud service model that delivers IT infrastructure, like servers and virtual machine services, to help enhance the storage capabilities of an organization.
- Platform-as-a-Service (PaaS) provides a complete environment for application development and management capabilities on the cloud. This includes middleware, development tools, database management systems and data security-related infrastructure.
- Software-as-a-Service (SaaS) provides enterprise business software (CRM/Customer Data Platforms (CDP)/mobile apps, etc.) on the cloud on an elastic basis where the business can procure end-user licenses in line with changing demands of the organization.
Popular cloud deployment models
- Private Cloud or the on-premises cloud is a cloud computing service implemented within the organization and limited for access to its employees. For a private cloud, although provided by a third-party cloud vendor, the control and governance rests with the organization's IT department.
- Public Cloud is a service, or a group of services, that can be accessed by any organization on PaaS pay-as-you-use basis. Public clouds offer the greatest level of efficiency and flexibility for an organization for an optimal utilization of shared IT resources.
Gartner predicts the worldwide public cloud services market is expected to grow 21.4 percent in 2018 to $186.4B, as compared to $153.5B in 2017.
- Hybrid cloud, an amalgamation of private and public cloud, helps businesses spread the individual aspect of their IT operations in the most efficient environment possible. With a cohesive strategy and robust monitoring, hybrid cloud can deliver the right business results with optimal cost savings. If implemented properly, all environments in this model work together and provide a seamless user experience.
