Companies will focus on cost optimization, enhanced security, and finding the best fit for their applications among various cloud features and services. Using multiple cloud services provides optionality, allowing businesses to allocate workloads to the cloud provider that best suits their capabilities, instead of relying solely on one provider.

According to International Data Corporation (IDC) research, the global expenditure on public cloud services is expected to reach a whopping US$1.3 trillion by 2025. But what is multi-cloud, exactly? In simple terms, it is an advanced cloud computing model that allows for easy, scalable, and flexible connections between various public clouds and on-premise workloads. Since most organizations already use at least one public cloud, and these typically work in tandem with on-premise workloads, the next step for many is to seamlessly integrate multiple cloud service providers into their environments.

Multi-cloud deployment allows organizations to use multiple Infrastructure-as-a-Service (IaaS) vendors or utilize different vendors for IaaS, Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) services. This approach provides the flexibility to run workloads on any cloud platform depending on the specific business needs. It ensures consistent migration, management, and security of applications, regardless of where they are deployed.

It's important to be cautious when adopting a multi-cloud approach. Although it comes with many benefits, it also presents new challenges. Therefore, it's crucial to be aware of and manage any potential risks associated with your infrastructure, as well as the data being distributed across multiple cloud providers. Without a well-thought-out plan to oversee and manage a multi-cloud environment, what could be one of the most exciting advancements in computing may turn out to be a resource-draining IT initiative that fails to deliver on its promise.

Multiple challenges in a multi-cloud environment

As more businesses embrace the advantages of multi-cloud, they face significant challenges in managing a multi-cloud environment.

Complexity and management:

Cloud providers have started offering specialized services that cater to specific and ever-changing business needs. While this is beneficial, managing multiple cloud environments from different providers can add complexity to your IT infrastructure. Every cloud provider may have its own set of tools, APIs, and management interfaces, which can require extra effort to integrate and coordinate operations across platforms. As these technologies continue to evolve, they may become even more complex, leading to increased costs, resource allocation issues, and potential security risks that cannot be ignored.

Interoperability and compatibility:

Interoperability and compatibility are two important factors to consider when using cloud services. Applications and services designed for one cloud provider may not work seamlessly across other providers. If you plan to move your applications between different clouds, you may face complexities and time-consuming tasks that require you to modify or redesign your applications to adapt to different infrastructure and service offerings.

Poor interoperability hinders agility and your ability to leverage specific cloud features or tools, which can negatively impact your business. It is important to keep your cloud-selection strategy up to date to meet your workload needs and take advantage of the best available services. In case a specific workload needs to scale significantly and quickly, you need to choose between various platforms and capabilities carefully.

Security and compliance:

Maintaining security and compliance across multiple cloud environments can be complex and challenging. With a multi-cloud architecture, there is an increased risk of cyber-attacks due to the different security controls and compliance standards of each cloud service and platform. Ensuring proper identity and access management mechanisms is also a challenge, as it involves providing secure access to various systems and processes for employees. As cloud features and services evolve, it is crucial to have appropriate workflows, controls, and procedures in place. Therefore, careful coordination and monitoring of security and compliance needs is essential.

Rising costs:

One of the major concerns for businesses adopting a multi-cloud strategy is the rising costs associated with it. While multi-cloud offers greater flexibility, it can also lead to overlapping services and capabilities across multiple cloud providers, which can quickly drive up expenses. Additionally, transferring and accessing data between different clouds can result in egress fees that can significantly impact the overall costs. As a result, companies may need to invest considerable time and effort to negotiate favourable pricing agreements among multiple service providers and diverse pricing models.

Technical expertise:

To effectively manage multiple cloud platforms, specialized skills and technical expertise are required due to each provider's unique features and ecosystem. However, the demand for diverse skill sets can pose significant challenges in terms of recruiting and training qualified professionals, as well as retaining these experts amidst competition for talent and new digital economy skills. Nevertheless, acquiring new skills has become indispensable for achieving success.

Critical Factors in the Pursuit of Multi-Cloud Adoption

Insightful guidance is available for designing and implementing effective multi-cloud environments that meet businesses' unique needs. Key considerations and digital solutions can support success.

Multi-cloud architecture:

Creating a robust multi-cloud architecture comes with its own set of challenges. It's important to understand these challenges and incorporate the right set of tools and technologies to support workload placement across diverse platforms and services. To effectively manage multi-cloud use, it's imperative to have a solid operating model that encompasses process security, technology, financial operations, and people and skills.

The key is to align IT service management with your multi-cloud operating model by implementing the right technology to effectively operate, manage, monitor, and secure resources and services among providers.
