Decoding Cloud Complexity: Is Multi-Cloud or Single Cloud Your Best Choice?  

At the start of the cloud computing revolution some 20 years ago, when companies saw the benefit of moving off-premise, single cloud was the only choice. Fast-forward to 2023 and you may be asking yourself, “is single cloud still the best choice?” Once cloud computing evolved and adoption rates increased, major players like Microsoft Azure entered the marketplace and laid the groundwork for multi-cloud strategies. Like all technology, cloud management and integration tools have increased in sophistication over time, giving organizations greater flexibility in handling their cloud management solutions and thus driving the adoption of multi-cloud strategies.

What exactly is multi-cloud?

While single-cloud describes using services, infrastructure and resources provided exclusively by a single cloud provider, multi-cloud refers to scenarios where multiple cloud providers deliver cloud services.

Multi-cloud or single-cloud? How do you choose and when should you move?

With sophistication comes complexity. As IT needs become more complex, businesses realize that a single cloud provider may not be able to meet all their requirements optimally. For that reason, multi-cloud has gained significant traction, especially among large enterprises with diverse needs. However, single-cloud environments remain popular with SMBs and mid-sized enterprises. But the complexity of needs isn’t the only reason businesses consider moving away from the single cloud solution. To identify when it’s time to move to a multi-cloud solution means first understanding the advantages and disadvantages of each strategic approach. Single-cloud solutions can deliver simplicity and streamlined, centralized management but fall short on scalability, flexibility and inherent downtime risk. Multi-cloud options, on the other hand, offer organizations greater flexibility in tools, infrastructure and services while delivering inherent redundancy while also eliminating single-vendor dependency.

Single-cloud benefits

The core characteristic of a single cloud approach is consolidating all IT resources within a unified infrastructure, where all digital assets, applications and data are hosted and managed within the ecosystem of one cloud platform. This unity simplifies the architecture, which fosters cohesion and centralized control. But there are two sides to every story. First, let’s look at the benefits of a single cloud approach:

• Cost-effectiveness and simplicity: Managing and maintaining a single cloud environment is inherently simpler, often translating to more straightforward workflows and a lower likelihood of errors
• Centralized management and streamlined updates/upgrades: Allowing IT teams to focus on optimizing performance, security and efficiency within a unified infrastructure
• Streamlined vendor relationship: With a single point of contact for support, billing and service

Single-cloud drawbacks

While a single point of contact can be perceived as a benefit, it also poses a potential risk by making an organization dependent on one vendor. Single-cloud relationships can potentially lock your organization into pricing, services and technologies. Additionally, one source means a greater risk of downtime in the event of failure. Finally, as technology evolves, single-cloud solution providers don’t always have the capabilities to keep pace, which can result in performance bottlenecks and unplanned cost increases.

Multi-cloud benefits

When organizations distribute their workload across different cloud platforms instead of relying on a single provider, they are considered a multi-cloud user. Why has adoption increased for multi-cloud solutions? The benefits can be boiled down to these 4 considerations:

1. Reduced downtime: With multiple cloud providers, workloads are distributed across the ecosystem, meaning that if one cloud provider struggles, workloads can be seamlessly shifted to other providers to ensure continuous operations.
2. Best-of-breed services: Different cloud providers may excel in different areas, like AI, big data or machine learning. Multi-cloud allows organizations to build their own best-in-class environment based on their unique business needs.
3. Flexibility and scalability: By their very nature, multi-cloud strategies allow more options for scaling and flexibility to adapt quickly to ever-changing business needs.
4. Compliance and data sovereignty: As regional data laws expand, multi-cloud solutions allow organizations to maintain compliance by storing data in different geographic locations.

However, just like their single-cloud counterparts, multi-cloud solutions are not without their challenges. In the case of multi-cloud solutions, the challenges include greater complexity, which requires organizations to support a strong IT team and robust tools to orchestrate and coordinate efforts. Data and application interoperability and integration across multiple cloud platforms can be daunting. Additionally, overall system costs can escalate without close monitoring. And finally, ensuring consistent security policies across different clouds is complicated, to say the least.

Security in a single cloud environment

Security measures in the simpler single cloud environment include a unified security framework, centralized monitoring to identify and respond to potential threats, and consistent compliance standards across all data and applications. On the downside, relying on a single provider can limit customization, making the creation of custom-tailored security measures more challenging.

If you’re concerned about your organization’s single-cloud solution strategy, here are 3 ways to mitigate that risk:

1. Interoperability planning. Adopting industry standards for interoperability so data and applications can be easily migrated if needed.
2. Redundancy and Disaster Recovery Planning. Replicating data and applications across geographically diverse data centers.
3. Continuous evaluation. Monitoring your cloud provider regularly for updates, features, and technological advancements to ensure they continue evolving with your needs.

Security in a multi-cloud environment

Whereas single-cloud security is simple, multi-cloud security can be complex, as different cloud providers may support distinct security protocols that the organization must navigate. Organizations must balance their cohesive defense strategy and the need for seamless interoperability between cloud platforms. Additionally, every data transfer between cloud platforms represents an additional security risk; encryption and practices that ensure secure data transfer are critical requirements. Some business verticals, such as those in the finance and banking sector, need a powerful multi-cloud strategy to run their enterprise while also requiring enhanced security and compliance from their cloud partners. Sectors like this have provided a playbook framework for all other business verticals to adopt. In general, the best approach for maintaining data security and regulatory compliance is to:

• Centralize security management
• Employ robust encryption and tokenization mechanisms for data at rest and in transit
• Implement continuous monitoring tools
• Conduct regular security audits across all cloud platforms
• Automate compliance checks and adhere to regulatory standards

When is it time to go multi-cloud?

As you can see, both single-cloud and multi-cloud solutions offer benefits and drawbacks. So how do you know what to choose? The answer is…it depends. In certain situations, a multi-cloud solution is an advantageous strategy. Do you see your organization in any of these scenarios?

• You have diverse workload requirements or geographic requirements.
• You rely on high availability and minimal downtime, such as e-commerce.
• You’re looking to optimize cost and avoid vendor lock-in.

Large global enterprises with operations in diverse regions typically rely on a multi-cloud strategy, as do tech startups with variable workloads like fluctuating user demands and rapid development cycles.
