What is multicloud?

In a nutshell, multicloud is an IT environment that utilizes two or more cloud services from different providers in a single setting. In simpler terms, multicloud distributes workloads and applications across multiple cloud providers rather than relying on a single cloud environment. This approach allows organizations to choose the best services and features from various cloud providers based on their specific requirements rather than being locked into a single vendor.

However, adopting a multicloud strategy can be challenging for organizations. It requires navigating complex vendor relationships, managing multiple data management tools and user interfaces, and ensuring interoperability and data portability across different cloud platforms. It's crucial for IT managers, CTOs, and developers to carefully evaluate their requirements and choose the right multicloud strategy and tools for their organization to realize the full benefits of this approach.

Now that we've explained what multicloud is, let's see why adopting a multicloud strategy is crucial for your business.

Why multicloud adoption is growing

Multicloud has become increasingly relevant and essential in 2023 due to the growing digital transformation trend and the need for organizations to modernize their IT infrastructure. With the rise of cloud computing, there has been a proliferation of cloud providers, each offering its own features and services. Multicloud allows organizations to take advantage of this diversity and choose the best services from multiple cloud providers based on their needs.

The critical benefit of multicloud is its ability to offer greater flexibility, agility, and cost-effectiveness for organizations. By leveraging multiple cloud providers, organizations can avoid vendor lock-in, negotiate and manage costs more effectively, and minimize the risk of downtime or data loss. Multicloud environments can also enable organizations to leverage best-of-breed technologies from different providers, scale up or down based on demand, and streamline compliance with regulatory requirements.

Multicloud examples are infinite and depend on an organization's needs. For example, a composite multicloud architecture for software-as-a-service (SaaS) applications that work well together will be hosted and served by two or more cloud service providers. A redundant multicloud architecture, on the other hand, involves hosting two or more instances of the same application by different providers for failover and application performance management purposes.

Hybrid cloud vs multicloud — what’s the difference?

Hybrid cloud and multicloud are popular cloud computing models with unique advantages and disadvantages. Understanding the differences between these two models is crucial for IT managers, CTOs, and developers to choose the suitable model for their organization's needs. This section will provide a technical and thorough comparison of hybrid cloud vs multicloud.

Multicloud computing uses multiple public clouds from different service providers to exploit each provider's attributes. The key characteristic of a multicloud model is that it incorporates two or more public clouds from different providers. This model offers extremely flexible functioning by spreading services and resources across providers.

On the other hand, hybrid clouds use a combination of public and private clouds. Hybrid clouds can also include on-premise cloud infrastructure. A company may integrate on-premise infrastructure with a public cloud for various reasons. For instance, the company may have a legacy infrastructure they want to avoid migrating to the cloud. Also, some businesses, like banks and credit card operators, prefer to implement specific hardware, databases, or data centers within their companies to maintain control of specific resources.

The main difference between multicloud and hybrid cloud is that multicloud leverages multiple public cloud providers to enhance resiliency, performance, scalability, and compliance. In contrast, a hybrid cloud leverages an organization's existing infrastructure and a public cloud provider to ensure customized compliance with security standards (e.g., 321 backup rule), government regulations (e.g., GDPR), and company policies (e.g., risk diversification).

Businesses can adopt several multicloud strategies depending on their specific needs and requirements. Multicloud examples include Cloudification (where cloud applications are hosted on-premises to improve performance and avoid lock-in) and MultiCloud Relocation.

While you can dive deeper into multicloud strategies, it's also essential to consider the different types of multicloud deployment models. A proper deployment model can provide enhanced security and performance.

In particular, multicloud deployments fall into composite and redundant deployment models:

  1. Composite deployment model: workloads are spread across multiple providers, depending on cost-efficiency and specific capabilities. Examples of this deployment model include Tiered Hybrid Pattern and Cloud Analytics Pattern.
  2. Redundant deployment model: while the previous model distributes data across providers, this one increases security by making copies of the same workload on multiple systems to avoid failures. Examples of this model include Active-Active and Public-Private.

Best practices for multicloud implementation

Here are some insights for IT managers, CTOs, and developers on implementing multicloud:

#1 Set a standard across environments

When adopting multiple services and systems, the challenge is to have a uniform approach and SLAs across environments.

This can be done by setting a protocol standard for storage, security, and user monitoring/tagging. And remember to create a centralized code repository.

Also, it's essential to analyze workloads and know the most efficient environment for them. A best practice here is to map workloads to understand when you don't need them or if you should move them to another domain.

Finally, you should keep an overview of everything to anticipate downtime and security issues. You can check different cloud monitoring tools here to consolidate your security system.

Regarding multicloud security, preparing a proper response plan, adopting end-to-end encryption, and following all the best practices is crucial.

#2 Containers are your way to a fully-integrated environment

Moving from one environment to the other is a significant challenge of multicloud. Containers make your workloads portable.

The benefit of this is that you can move apps and data from one cloud to another without incurring performance roller-coasting. Also, it will be easier to make services available again (i.e., in case of downtime) by moving them to another platform.

To achieve this, you should educate your employees on best practices, adopt a container repository, and use the proper service (e.g., Kubernetes for MultiCloud portability).

#3 Be cost-efficient

When using multiple cloud services, getting lost among different, non-transparent costs is easy. On one side, you should follow the best practices. On the other, a tool enabling a unified view can help.

In particular, a suggested best practice is building a self-service, unified consumption system so developers can operate and adopt environments and platforms on demand. On top of that, this practice will also help cost optimization since it will signal the presence of a lower-cost service and the actual budget available.

Cost-efficiency doesn't only mean spending less money. Manual processes take out a lot of time and focus. Therefore it's also imperative to automate processes.

#4 Adopt a hybrid multicloud strategy

When implementing a multicloud strategy, you should avoid religiously sticking to it. Instead, consider adopting different IT models from the edge to on-premise and the cloud.

This way, you can have high performance and protection on mission-critical data and offload all the rest offsite for risk diversification and cost-optimization.

4 key multicloud security challenges

As businesses continue their digital transformation journey, they increasingly adopt multicloud environments to support their growing flexibility, scalability, and cost-efficiency needs. Multicloud environments enable organizations to deploy workloads across different cloud providers, which allows them to take advantage of unique services offered by each provider and avoid vendor lock-in. However, multicloud environments also introduce new security challenges that IT managers, CTOs, and developers must be aware of and address. This section will discuss 4 critical multicloud security challenges and provide best practices for addressing them.

#1 Fragmented security solutions

In a multicloud environment, organizations often use various vendor security tools to manage different cloud platforms, leading to a fragmented security solution. This can create gaps in security coverage (e.g., increased attack surface), complexities and reduce visibility into threats. To address this challenge, organizations should adopt an integrated approach to security that leverages automation and centralized management.

Best practices:

  • Implement a security platform that can provide a unified view of security across all cloud platforms.
  • Automate security tasks.
  • Provide real-time threat intelligence.

#2 Shared responsibility

Cloud providers follow a shared responsibility model where they are responsible for securing the infrastructure, while organizations are responsible for ensuring their workloads. This model can lead to confusion about who is responsible for what, resulting in security gaps. Organizations should clearly define their security responsibilities to address this challenge and ensure their cloud providers meet their security obligations.

Best practice: Develop a comprehensive security strategy that includes security controls, compliance requirements, and risk management. Establish clear security responsibilities with your cloud providers and monitor their compliance regularly.

#3 Compliance

In 2023, maintaining compliance is critical for businesses that want to avoid hefty fines and losing important customers.

When adopting multiple services from different countries and legislations, checking everything is crucial to avoid nasty surprises.

Best practice:

#4 Increased attack surface

While diversifying through multiple cloud services it's good from a disaster recovery perspective, on the other hand, this process makes the system more likely to be a target of cyber attacks.

Best practice: follow the digital hygiene best practices, in particular, keep your systems updated, train your employees, avoid IT shadowing, set access rights properly, and more.
