Moving to the cloud is no small feat, especially for enterprise-scale infrastructure. And just imagine the complications when you need to deploy across more than one cloud. Multi-cloud deployment is sometimes characterized by slow, error-prone workloads, lack of consistency, and inflexibility that holds users back.
In this blog, we’ll provide clear definitions, use cases, benefits, challenges, and factors to consider for multiple-cloud deployment. Then we’ll close by laying out how scalable multi-cloud automation makes it all so much smoother.
Multi-cloud deployment is when one organization deploys resources like infrastructure, platform, or software across multiple public and private cloud providers, like Amazon AWS, Microsoft Azure, Google Cloud, and others.
There are three basic types of resources provided in the cloud:
Organizations do multi-cloud deployment because deploying across clouds provides choice of functions, specific strengths, and cost savings.
No single cloud provider does everything an organization might need to do in the cloud. If one tool does some of the things you need while another does the rest (or a combination), multi-cloud deployment might be the only way to operate in the cloud. Having to choose between one tool and another might make cloud deployment impossible or unrealistic, especially for larger organizations with more complex or diverse infrastructure (like information technology in government, for example).
Also, some cloud providers may be better known for specific services than others. Amazon Web Services (AWS), for example, is the most established cloud platform on the market, so it has a larger user base and a reputation for reliability. If you need search built into your infrastructure, Google Cloud Platform (GCP) is king – it uses the same infrastructure as Google Search and YouTube.
Another benefit of multiple-cloud deployment is its ability to help control cloud computing costs. AWS, Azure, and Google each have their own pricing structure, which is itself a deciding factor for some deployments. But prices and billing increments for cloud services, like storage, change frequently. Multi-cloud deployment lets you diversify the tools you use so your entire cloud deployment doesn’t get locked into a pricing structure you can’t afford – or just don’t want.
Of course, deploying across cloud platforms doesn’t come without a measure of difficulty. Some of the common problems organizations face when moving to multi-cloud deployment include:
As you might’ve gathered, the main pain point for multiple-cloud deployment is that there’s not much standardization between cloud services. Each cloud does things a bit differently. There may be some similar constructs between certain types of PaaS cloud offerings (like SQL-based databases), but even then, there are dozens of specialized database services that may be better for different use cases.
That lack of standardization really becomes apparent when setting up and maintaining individual clouds. Infrastructure as code (IaC) tools like Terraform can be used to help reduce the complexity of setup, but this speed bump can still prevent organizations from efficiently using multiple cloud providers at once.
Multi-cloud automation is the process of automating deployment, configuration, and management of resources like IaaS, PaaS, and SaaS across multiple cloud platforms.
Almost anything can be automated in a cloud environment. That includes tasks that are fundamental to building and maintaining infrastructure. It also means you can automate application lifecycle management (ALM), from server/service provisioning to security to management to scaling to failure correction to destruction.
Automation in a cloud environment is focused on the timeless issues of Reliability, Availability, and Scalability (RAS). With automation, it’s easier to make sure environments are consistent, keep them in their proper state, and maintain self-healing systems.

There are many use cases for automation in a multi-cloud environment. For example, automation makes it easier to develop microservice architectures like Kubernetes that reduce single points of failure. It also allows you to scale services up and down when needed by rapidly deploying new systems and tearing down unnecessary ones.
Making the decision to deploy across multiple clouds (or to make changes to your current multi-cloud deployment) can have a huge impact on your development and operations. That’s where automation shines: It can actually make it easier to deal with complex multi-cloud environments.
Deploying in multiple environments almost always creates a skill gap. Remember how different each cloud provider can be? When members of a team become subject matter experts in one platform, the techniques and nuances they learn might not transfer to another cloud deployment. Automation can help your team bridge the skills gap by allowing different subject matter experts to develop reusable capabilities for others to leverage.

Automation can also minimize the differences between environments. By providing a consistent abstraction layer that bridges the individual cloud providers, it creates a more even playing field among clouds for your team to utilize. That means users don’t all have to be familiar with the differences between environments to utilize them properly. For example, you could write a set of Terraform configurations that allows users to deploy the same set of services on either AWS or GCP simply by passing a single configuration option.
But multi-cloud automation does more than fix and prevent cloud deployment problems. In addressing the friction points above, it gives architects and engineers new ways to develop environments. That leads to better, more resilient infrastructure across platforms.
Ultimately, any automation and configuration management tool you use for multi-cloud deployment shouldn’t care where you deploy. Puppet excels at not caring whether your operating systems are physical, virtual, on-premises, in the cloud, or in several clouds at once.
Puppet is one of the pioneers of using abstractions to manage configurations. Reusable components in Puppet are written by experts in individual technologies to be leveraged by users without specialized cloud skills. In other words, Puppet users get expert resources without having to become experts themselves.
