Exploring Cloud Computing Deployment Models

When selecting a cloud strategy, a business must consider a few factors, such as required cloud application components, preferred resource management tools, and legacy IT infrastructure requirements. The three main cloud computing deployment models are cloud-based, on-premises, and hybrid.

Cloud-based implementations

  • Run all parts of the application in the cloud
  • Migrate existing applications to the cloud
  • Design and create new applications in the cloud

In a cloud-based deployment model, businesses can either migrate their existing applications to the cloud or develop new applications directly in the cloud environment. This approach offers numerous advantages and options for organizations.

Migrating existing applications to the cloud involves transferring the application’s infrastructure, data, and functionalities from on-premises or traditional hosting environments to cloud platforms. This migration process can vary depending on the complexity and architecture of the application. Cloud migration enables businesses to leverage cloud infrastructure’s scalability, reliability, and cost-efficiency while potentially reducing their on-premises hardware and maintenance costs.

On the other hand, designing and building new applications in the cloud allows organizations to take full advantage of the cloud’s capabilities from the start. Cloud-native development involves creating applications optimized explicitly for cloud environments, utilizing cloud-native services and technologies. This approach enables businesses to leverage cloud platform scalability, elasticity, and availability.

When building applications in the cloud, organizations can use either low-level infrastructure or higher-level services, depending on their specific requirements and resources. With low-level infrastructure, businesses have more control over the underlying components, such as virtual servers, storage, and networking. This gives IT staff granular control and requires them to handle tasks like provisioning, managing, and scaling the infrastructure.

On-site implementations

  • Deploy resources using virtualization and resource management tools
  • Increase resource utilization with the use of virtualization and application management technologies

On-premise deployment, also referred to as “private cloud deployment,” is a computing model where resources are deployed and managed locally within an organization’s premises. This approach involves utilizing virtualization techniques and resource management tools to effectively allocate and utilize computing resources. By implementing on-premise deployment, organizations can maintain complete control over their infrastructure and data, allowing them to adhere to specific security, compliance, and governance requirements.

In this deployment model, various applications and services can be hosted on technology that is fully maintained within the organization’s on-premises data center. This means that the organization has physical control over the hardware, networking equipment, and storage systems supporting their applications. By incorporating virtualization technologies, such as hypervisors, organizations can create multiple virtual machines (VMs) or containers on a single physical server, enabling better utilization of available resources.

While the on-premise deployment model shares similarities with traditional legacy IT infrastructure, the integration of virtualization and application management technologies brings several benefits. By abstracting the underlying hardware and creating virtual instances, organizations can optimize resource allocation, allowing for more efficient utilization of computing power, storage capacity, and network bandwidth. This increased resource utilization helps to minimize wastage and maximize the return on investment for the organization’s infrastructure.

 Hybrid Implementations

  • Connect cloud-based resources to on-premises infrastructure
  • Integrate cloud-based resources with legacy IT applications

In a hybrid deployment, the cloud-based resources are connected to the on-premises infrastructure. You may want to use this approach in various situations. For example, you have legacy applications that are better-kept on-premises, or government regulations require your business to keep certain records on-premises.

For instance, consider a scenario where a company aims to utilize cloud services for automating batch data processing and analysis. However, within their existing IT landscape, they possess several legacy applications that are not compatible with or optimized for cloud migration. In this case, a hybrid deployment would enable the organization to maintain the legacy applications on-premises while still taking advantage of cloud-based data and analytics services.

By adopting a hybrid deployment model, the company can keep their legacy applications running smoothly and benefit from the scalability, flexibility, and advanced analytical capabilities offered by the cloud. They can offload the resource-intensive tasks, such as data processing and analysis, to the cloud environment, taking advantage of its robust infrastructure and elastic computing power. This approach allows the business to achieve efficient data processing and gain valuable insights while preserving the functionality of their on-premises legacy applications.

Benefits of cloud computing

When businesses consider adopting cloud computing, they can reap numerous benefits that significantly impact their operations and overall success. These advantages can influence a company’s decision to adopt a specific approach to cloud computing, aligning it with their specific business needs and goals. Let’s explore some of the key benefits and why they are compelling considerations.

  • Change the initial expense for variable expenses: Cloud computing allows organizations to shift from large upfront capital expenditures to more manageable variable expenses. Instead of investing in costly on-premises infrastructure and hardware, businesses can pay for cloud services based on their actual usage, scaling resources up or down as needed. This pay-as-you-go model provides financial flexibility, enabling companies to optimize their IT spending and allocate resources more efficiently.
  • Stop spending money running and maintaining your data center: With cloud computing, businesses can offload the responsibility of running and maintaining their own data centers. This eliminates the need for companies to invest in dedicated IT staff, physical security measures, cooling systems, and other infrastructure-related expenses. By leveraging cloud service providers, organizations can focus their resources and efforts on core business activities, while relying on experts to manage and maintain the underlying infrastructure.
  • Stop estimating capacity: Traditional on-premises infrastructure requires businesses to forecast their capacity needs and invest accordingly, often leading to either underutilization or costly overprovisioning. In contrast, cloud computing offers elastic scalability, allowing companies to seamlessly adjust their resource allocation based on demand. This agility eliminates the need to estimate capacity in advance, enabling businesses to respond quickly to changing requirements and avoid costly underutilization or performance bottlenecks.
  • Benefit from large economies of scale: Cloud service providers operate massive data centers, benefiting from economies of scale that individual organizations cannot match. By leveraging these resources, businesses can access cutting-edge infrastructure, advanced security measures, and specialized services at a fraction of the cost of building and maintaining them in-house. Cloud providers can spread their costs across numerous clients, resulting in lower costs per customer and enabling businesses to access enterprise-level infrastructure and services without the associated expenses.
  • Increase speed and agility: Cloud computing empowers businesses with enhanced speed and agility in various aspects. Provisioning and deploying resources in the cloud is typically faster than traditional infrastructure deployment, allowing companies to accelerate time-to-market for their products and services. Additionally, the cloud’s flexibility and scalability enable businesses to quickly adapt to changing demands, scale their applications seamlessly, and experiment with new ideas without significant upfront investments or operational constraints.
  • Acquire global scale in a matter of minutes: Cloud computing provides organizations with the ability to expand their operations globally without the need for establishing physical infrastructure in different locations. Cloud service providers offer data centers in multiple regions worldwide, enabling businesses to reach customers in diverse geographical areas efficiently. This global scale can be achieved within minutes, allowing companies to expand their market reach, serve customers more effectively, and unlock new growth opportunities.

The benefits of cloud computing make it an appealing choice for businesses seeking to optimize their operations, reduce costs, and increase agility. By shifting from upfront expenses to variable costs, eliminating data center maintenance burdens, and leveraging scalable resources, organizations can focus on core competencies and allocate resources more effectively. The advantages of large economies of scale, increased speed and agility, and the ability to achieve global scale rapidly make cloud computing a strategic enabler for business growth and innovation.
