• A lower complexity score supports better performance, stronger cloud governance, lower costs and higher return on cloud investments.

• Combining EMCI with a secure multi-cloud networking solution and reliable multi-cloud networking services helps organisations simplify cloud operations and scale with confidence.

Why is multi-cloud complexity becoming a boardroom-level concern?

As organisations expand across multiple cloud platforms, managing cloud complexity has become a business priority rather than just an IT concern. Different cloud providers bring unique networking, security and governance requirements, making effective multi-cloud management increasingly challenging. Poor visibility, inconsistent policies and rising operational costs can affect business performance, compliance and resilience. These issues influence strategic decisions around risk, investment and digital transformation. The Enterprise Multi-Cloud Complexity Index helps organisations measure cloud complexity, identify operational gaps and make informed decisions that improve governance, reduce risk and support long-term business growth.

What is the Enterprise Multi-Cloud Complexity Index (EMCI)?

The Enterprise Multi-Cloud Complexity Index (EMCI) is a framework that helps organisations assess the complexity of managing hybrid and multi-cloud environments. It evaluates key operational areas such as governance, security, networking, automation, visibility and workload management rather than focusing only on infrastructure. The framework helps IT leaders identify operational challenges, prioritise improvements and strengthen multi-cloud management. A higher EMCI score generally indicates greater complexity and increased business risk. When used alongside a robust multi-cloud management platform and a secure multi-cloud networking solution, EMCI helps improve governance, operational efficiency and long-term cloud performance.

The seven dimensions that drive enterprise multi-cloud complexity

The Enterprise Multi-Cloud Complexity Index evaluates several interconnected areas that influence overall cloud operations.

1. Cloud provider diversity

   Using multiple cloud providers increases flexibility but also introduces different management interfaces, networking architectures and operational processes. The greater the number of cloud platforms being managed, the higher the potential complexity.

2. Workload distribution

   Applications often operate across several cloud environments simultaneously. Managing dependencies, application performance and workload placement requires consistent governance and intelligent multi-cloud management to prevent operational inefficiencies.

3. Network connectivity

   Networking plays a critical role in hybrid and multi-cloud environments. Applications continuously exchange data between cloud providers, branch offices, data centres and users. Without a reliable multi-cloud networking solution, organisations may experience latency, inconsistent routing and fragmented visibility.

   Strong multi-cloud networking services help simplify connectivity while improving application performance across distributed environments.

4. Security and compliance

   Every cloud provider introduces different security controls, identity management models and compliance requirements. Maintaining consistent security policies across multiple environments becomes increasingly difficult as cloud adoption grows. EMCI evaluates whether security governance remains standardised throughout the organisation.

5. Operational visibility

   Many organisations use separate monitoring platforms for different cloud providers. This fragmented approach makes it difficult to obtain a complete picture of application health, network performance and infrastructure utilisation. An effective multi-cloud management platform should provide centralised visibility across every cloud environment.

6. Automation and standardisation

   Manual processes increase operational complexity. The Enterprise Multi-Cloud Complexity Index considers the level of automation used for workload deployment, policy management, configuration updates and infrastructure provisioning. Higher levels of automation generally reduce operational risk while improving consistency across cloud environments.

   Modern multicloud management tools help organisations automate routine operational tasks, allowing IT teams to focus on strategic initiatives rather than repetitive administration.

7. Governance and policy consistency

   Governance ensures cloud environments operate according to common business standards. EMCI evaluates how consistently organisations apply policies relating to security, networking, workload deployment, compliance and resource management across multiple cloud providers. Strong governance reduces operational risk while supporting business growth and regulatory compliance.

Together, these seven dimensions provide organisations with a comprehensive picture of their cloud operating environment.

Rather than simply identifying technical issues, the Enterprise Multi-Cloud Complexity Index helps business leaders understand how operational complexity influences performance, security, scalability and long-term cloud success.

How to calculate and benchmark your enterprise multi-cloud complexity score?

The Enterprise Multi-Cloud Complexity Index (EMCI) should be used as an ongoing assessment rather than a one-time exercise. Organisations can score key areas such as cloud provider diversity, networking, security, governance, automation, workload management, visibility and compliance using a consistent rating scale. Combining these scores provides an overall EMCI that can be tracked over time. Lower scores indicate well-managed cloud environments, while higher scores highlight greater operational complexity and potential business risk. Regular benchmarking helps organisations strengthen multi-cloud management, measure cloud transformation progress and identify improvement opportunities before operational challenges affect business performance.

Understanding what your EMCI score reveals about cloud risk

An Enterprise Multi-Cloud Complexity Index (EMCI) score shows how effectively an organisation manages cloud complexity. Lower scores indicate strong governance and efficient multi cloud management, while higher scores highlight risks such as poor visibility, inconsistent security and operational inefficiencies. Regularly reviewing EMCI helps organisations identify improvement areas, strengthen governance and reduce business risk before complexity impacts performance.

The business impact of high multi-cloud complexity

As cloud environments grow, managing them becomes more challenging. Without effective multi-cloud management, increasing complexity can affect costs, security, innovation and the overall value organisations receive from their cloud investments.

1. Rising operational costs

   Managing multiple cloud environments independently can lead to duplicated resources, inefficient workload placement and higher administrative costs. Better multi-cloud management and automation help optimise resources and improve cost efficiency.

2. Security blind spots

   Different security policies across cloud providers can create visibility gaps and increase risk. A secure multi-cloud networking solution helps strengthen governance and maintain consistent protection across environments.

3. Slower innovation cycles

   Operational complexity can slow application deployments and consume valuable IT resources. Simplified multi-cloud management enables faster deployments, greater automation and improved business agility.

4. Reduced cloud ROI

   Poor governance, fragmented tools and inefficient networking reduce cloud value. A robust multi-cloud management platform, supported by reliable multi-cloud networking services, helps improve performance, optimise resources and maximise return on cloud investments.

Who should use an Enterprise Multi-Cloud Complexity Index?

The Enterprise Multi-Cloud Complexity Index (EMCI) is valuable for any organisation operating across hybrid or multi-cloud environments. While it is particularly useful for large enterprises, businesses of all sizes can use the framework to understand how cloud complexity affects operations and where improvements are needed.

• CIOs and IT leaders: Gain a clear view of cloud maturity, operational risks and areas that require investment.

• Cloud architects: Assess workload placement, governance and infrastructure design across multiple cloud providers.
