Organizations feel pressure from today's technological world to move to cloud-based technologies. This is no surprise given the many benefits cloud services offer. But when it comes to cloud environments, which approach is best? The most prominent solutions are multi-cloud and hybrid cloud. What are the advantages and disadvantages of these approaches?

A multi-cloud strategy relies on multiple clouds from multiple vendors, which gives companies flexibility in choosing the best options for specific business operations. Hybrid cloud combines public and private cloud structures to facilitate seamless integration of data and applications.

To decide between a hybrid and multi-cloud environment, companies must consider budgetary constraints, future scalability needs, and current needs. Diving deeper into these two approaches will help you gain insights into the cloud infrastructure that is best suited for your business.

Background: Understanding the Basics

On-premises computing infrastructure is bulky, expensive, and limiting, especially for a remote workforce. Cloud computing offers users the storage and computing power they need through Internet-based platforms. This eliminates the need for a physical infrastructure.

Cloud deployments remain in a state of continuous parallel evolution, creating new configurations to meet technological advancements and evolving business needs.

Cloud Computing Overview

Cloud computing leverages the Internet to offer services such as networking, processing, and storage to minimize the need for physical storage and on-site facilities.

Cloud scalability ensures that businesses can easily adjust their resources based on fluctuating demands to help avoid overspending or underprovisioning. Its economics allow companies to reduce significant upfront hardware investments and instead pay only for the storage or computing power used. One of the most significant advantages of cloud computing in today's work-from-home world is its flexibility, allowing organizations to deploy applications and data to locations around the world.

Evolution of cloud models

Public and private cloud services laid the foundation for today's cloud service providers. The community model combined both clouds into suites to offer similar industries and types of clientele. In addition to these three models, four newer basic models have appeared.

The lift-and-shift model involves replicating local virtual machines and server infrastructure in the cloud. It offers businesses easy and secure access from third-party data centers and servers. The elastic/scalable model applies intelligent metrics to the cloud and allows services to scale up or down based on volume variations.

Using a more modular approach, the container model breaks cloud applications into building blocks to allow for easier updating of the necessary parts of the applications. This avoids issues with major app releases by making small, incremental changes. The microservices model leverages third-party cloud APIs rather than including them as parts of an application.

What is multicloud?

The multi-cloud approach involves using multiple cloud computing platforms or providers to support diverse business operations. Some companies use IaaS from a public cloud provider to host diverse workloads while also using more specialized services such as SaaS or PaaS for other business services.

Advantages of multicloud

Multi-cloud offers organizations many compelling advantages. Using multiple suppliers allows companies more flexibility and makes it easier to scale up or down services. Working with multiple cloud vendors allows them to choose which provider to use for each aspect of their storage needs to keep private data secure while eliminating vendor lock-in. By distributing resources across multiple platforms, users benefit from greater reliability and backups.

Comparing Multi-Cloud and Hybrid Cloud

Hybrid and multi-cloud models offer many benefits to companies while accommodating diverse organizational challenges and needs. Company decision makers should take the time to learn the distinguishing factors of each and how they apply to the company's unique situation, while also evaluating model and service provider options.

Use case suitability

Choosing between a hybrid or multi-cloud approach depends on the organization's needs and desires. Each cloud version offers advantages and disadvantages, all of which require careful consideration. Companies that prioritize data security often choose hybrid cloud because its private cloud component provides a secure environment to protect data.

Companies with a broader range of services or related to specialized tasks tend to gravitate toward multicloud so they can choose the best offerings from each provider. This helps ensure better performance and functionality.

Cost Considerations

Hybrid cloud and multi-cloud models present their own cost complexities. While hybrid clouds provide companies with a private and public cloud and potential savings associated with this balance, setting up and maintaining the private component is sometimes expensive. The nature of the multi-cloud route adds additional complexities to the pricing structure due to the varying pricing models of prospective cloud providers.

Performance and scalability

Before venturing into the world of enterprise-level cloud computing, decision-makers should carefully consider the performance and scalability required now and in the future. The hybrid cloud approach offers inherent scalability capabilities, utilizing the public cloud for periods of high demand and the private cloud for consistent loads. However, transferring between the two may mean reduced performance speed. Multi-cloud allows companies to rely on the strengths and performance of multiple vendors, but creates the possibility of latency in some scenarios.

Security Implications

Security should always be an important consideration when choosing a cloud provider(s) and approach. Security consistency is a challenge in a multi-cloud approach due to the number of different service providers and their varying protocols and standards. This strategy involves the use of multiple vendors, which means that companies must evaluate each vendor's environment for different security strategies and needs. Otherwise, they risk creating vulnerabilities.

The hybrid cloud offers more security by allowing data to be split between clouds. The most sensitive or private data remains in the more controlled private cloud, while the public cloud houses less critical workloads. While this option helps increase security, ensuring secure and seamless data flow between the two clouds requires additional robust security measures and continuous vulnerability monitoring.

Making the Right Choice: Factors to Consider

Choosing a cloud computing model and cloud service providers is not a simple task. Companies must do their due diligence to understand what they need in a model and vendors, what they want to avoid, and any other critical aspects of their specific use cases.

The main factors to consider when making this decision are:

1. Organizational needs : Start with a thorough assessment of the organization's requirements. For example, some organizations need to prioritize the security of their data over the ability to scale up or down quickly. Other companies need to utilize cloud technology with simple maintenance and management requirements to avoid skills-based issues. Some companies want the benefits of using multiple service providers simultaneously across different clouds.
2. Budget Constraints : Over time, hybrid cloud and multi-cloud models offer cost savings to businesses. However, each model has financial implications that companies must consider. A hybrid cloud is typically more expensive than an on-premises infrastructure and multi-cloud approach due to the need for a combination of on-premises, private, and public cloud resources. The multi-cloud approach is more cost-effective because companies have the ability to choose the most cost-effective public clouds for their individual workloads. Working with either cloud model also requires additional IT and cloud maintenance costs.
3. Future scalability : Although companies cannot predict the future, they should try to anticipate growth in terms of their IT needs. The model you choose must offer the right level of flexibility to adapt to the evolving dynamics of the business without breaking the bank. Both options offer solutions to scale up or down on demand, each with its own advantages and disadvantages.
4. Technical expertise : Hybrid and multi-cloud systems offer their own strengths and weaknesses regarding associated maintenance and management costs. Choosing the multi-cloud approach is generally cheaper and easier to manage than the hybrid option. However, it offers less flexibility in application and workload placement. Although more expensive and complex in management needs, hybrid cloud makes it easier to choose where to place each application or data set.

Conclusion

There is no single “best” solution when it comes to choosing an approach to cloud computing. Hybrid cloud and multi-cloud models are excellent solutions to meet a variety of business needs. Multi-cloud offers the flexibility to leverage multiple providers to optimize services and leverage the strengths of each cloud. Hybrid cloud offers companies a balance between control and scalability, using public and private clouds.

The key to making the right decision between the options lies in companies understanding the strengths and weaknesses associated with each option and following careful and detailed planning before signing any contract. Some of the most important factors to consider in this choice include the company's anticipated growth, data security priorities, budget constraints, and technical expertise or limitations.
