The COVID-19 crisis worked as a catalyst to accelerate the customer demand for cloud-based services. The sudden rise in cloud spending by 37% in the first quarter of 2020, which is around $29 billion, is the evidence of this change. With the shift in work culture and customer demand, tech infrastructure companies experience the urgency for scalable, secure, reliable, cost-effective off-premises technology services. That is the cause of cloud spending enhancement, despite the inevitable economic downturn. According to industry analyst Gartner, cloud spending is forecast to reach $332.3 billion in 2021 from $270 billion in 2020, an increment of 23.1%.
Considering the enormous benefits of cloud adaptation, modern businesses prefer to adopt cloud. But the cloud is not just one thing—there are three types of cloud computing with different features and advantages. When you plan to adopt cloud for your business, you can choose from those three options: public, private, and hybrid cloud. Here is brief information about those three cloud models that can help you to choose the right option for your organization.
This is the most popular cloud service model, owned and operated by third-party service providers. Here the services are delivered through the internet, and the service provider takes care of the maintenance of the cloud service and infrastructure.
Public cloud services offer the pay-as-you-go service model. That makes this cloud service economical for organizations with varying needs. Public clouds can also handle smaller amounts of data, making it suitable for small and mid-sized companies.
No CapEx requirement: No investments need to deploy and maintain the IT infrastructure.
Near-unlimited scalability: High flexibility and scalability to meet unpredictable workload demands.
No maintenance: The service provider provides the maintenance.
Affordability: Flexible pricing options. Reduced need for in-house expertise, hardware, etc.
- Minimal technical control
- Lack of security and control over the hardware
- Lack of cost control
- Small and medium-sized organizations with limited budgets can avail public cloud services to utilize the benefits of cloud computing. When companies need to provide communication services for a specific number of users or meet additional resource requirements, etc., they can go for the public cloud.
Private clouds consist of computing resources used exclusively by a single organization or entity. In this model, the hardware, software, and any related infrastructure is either located at your organization’s on-site data center or is located in a controlled environment of a service provider. Here the computing resources remain isolated and delivered solely to your organization via a secure private network. So, it becomes easier for organizations to customize their resources to meet specific IT needs.
Exclusive IT environment: Dedicated and secure environments solely for your organization
Optimum Scalability: High scalability and efficiency to meet the business-specific demands without compromising on security and performance
Maximum control: As resources are not shared, higher levels of control and privacy are possible.
More flexibility: One can customize its cloud environment to meet the ever-changing business, and IT needs of the organization.
- Mobile users may have difficulty to access the private cloud considering the high-security measures in place.
- Highly regulated industries, like government agencies, financial institutions, mid- to large-sized companies with business-critical operations seeking enhanced control over their environment
- Companies deal with sensitive data and can afford to invest in high performance and available technologies
This cloud computing model offers a cloud infrastructure environment that combines public and private cloud solutions with a coherent synchronization. A hybrid cloud allows users to move applications and data between a public and a private cloud. Most companies prefer hybrid cloud considering the massive advantages, such as greater flexibility, better deployment options, security, compliance, and getting more value from the existing infrastructure. This cloud computing also offers businesses the ability to seamlessly scale up their on-premises infrastructure to the public cloud and also handle any overflow without giving third-party data canters access to the entirety of their data.
Seamless scale-up: It allows flexible and policy-driven deployment to distribute workloads across public and private infrastructure environments as per security, performance, and cost requirements.
Scalability with security: It allows the scalability of public cloud environments without exposing sensitive IT workloads to inherent security risks.
Cost efficiency: allows users to better manage budgets without compromising security and work efficiency. Here you can run sensitive IT workloads on dedicated resources in private clouds and continue the regular workloads on inexpensive public cloud infrastructure.
- Chance of wasteful spending.
- Added complexity in infrastructure due to the mix of private and public cloud architecture.
- Organizations that serve multiple verticals and face different IT security, regulatory, and performance requirements
Opting for public, private, and hybrid cloud solutions depends on multiple regulatory factors, business-specific requirements, and limitations. You need to do thorough research to find the exact business requirements that can help to opt for the most suitable cloud solution for your organization.
