In the multi-cloud era, it’s important to embrace cloud on your terms. A cross-cloud strategy, or multi-cloud, enables better scalability, security, and disaster recovery in today’s challenges that are fueled with hyper availability demand and data sovereignty concerns.

After you start experimenting with techniques like multi-region deployments, a proper tooling stack is required to automate tasks and optimize costs as a multi-cloud strategy is crucial to build a scalable and resilient infrastructure.

That's where infrastructure-as-code tools become key in navigating cross-cloud architectures, and here are a few tools to help you with that:


Ansible is, above all, an automation tool. With the right content, such as roles, modules, or other plugins, Ansible can automate almost anything. Cloud management is no exception. This means that we can automate our provisioning processes quite easily. you'll be able to orchestrate, configure management, deploy apps, provision, continuous delivery, and security and compliance on all cloud products (load balancers, containers, firewall, and so on).


Terraform is an open-source infrastructure-as-code software tool that enables you to safely and predictably create, change, and improve infrastructure.

You may have to adapt your code to the cloud provider, to adapt to resources, for instance, or define your resources in a cloud-agnostic way in a simple config to create a multi-cloud environment,
Terraform provides extensive customization, scalability, and version control of infra code and ensures parity between various environments (Dev, QA, Prod).

Here is a guide to start on Terraform.


Pulumi is an open-source infrastructure as code SDK enables you to create, deploy, and manage infrastructure on any cloud using your favorite languages.

It is quite new a new tool, the first sable version came out in late 2019, but thanks to their active and growing community, they evolve quickly. Pulumi gives you the ability to add more logic to your infrastructure code. Unlike Terraform, which is declarative, Pulumi is procedural. For instance, you can take advantage of programming languages like Python to add loops, conditions, and functions. All the power of classic programming languages is available to the infrastructure-as-code here. They support Python, NodeJs, and Go.


Kubernetes is a cloud-agnostic open-source tool that changed how we work on infrastructure. It is a portable and extensible platform for managing containerized workloads and services that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem and community.

The learning curve for self-managing Kubernetes can be quite intense, and we provide a fully managed Kubernetes.


Through a multi-cloud management solution, Rancher gives control back to operations while offering flexibility and ease of use for developers. 100% open-source software with zero lock-ins, Rancher fits perfectly with your multi-cluster, hybrid, or multi-cloud container orchestration strategy.


Cloudify is an open-source, multi-cloud orchestration platform that packages infrastructure, networking, and existing automation tools into certified blueprints.
With Cloudify in play, all private, public, VMs, and Kubernetes workloads turn into certified environments that can automate DevOps operations, governance, and compliance processes, as well as support cloud migration.

The platform integrates with IT-SM tools that turn approval workflows into full life cycle management - saving weeks and months of manual work per ticket.


VirtEngine is an open-sourced cloud management platform designed to be simple for the user and implement the latest technologies to improve functionality. VirtEngine supports multiple forms of Cloud Computing such as IaaS, PaaS, STaaS, and SaaS.


Istio addresses the challenges developers, and operators face with a distributed or microservices architecture. Whether you're building from scratch or migrating existing applications to cloud-native. You can multi-cloud archive on Istio.


Openstack is an open-source cloud management platform that enables organizations to control large pools of compute, storage, and networking resources. It has a wide range of features such as virtual networks, bare-metal support, container support, integrated VM and container support, VLAN-aware VM support, and more. OpenStack works with many open-source technologies, which makes it a great choice for heterogeneous infrastructures.

Kubernetes Kosmos

Last but not least, how not to mention Kosmos? Scaleway Kubernetes Kosmos is a true Cross-Cloud Kubernetes engine that leads the way toward network and device interactions on a global scale.

Kubernetes Kosmos gives you a fully managed Kubernetes engine for multi-cloud, with the possibility for any server or Instance, including Elastic Metal, to join a Kubernetes Kosmos cluster.

Learn how to set up your first multi-cloud Kubernetes cluster on Kosmos.

…And all the CNCF Projects

You can also keep an eye on all the CNCF projects - of which Scaleway is a proud member. CNCF is the open-source, vendor-neutral hub of cloud-native computing, hosting projects like Kubernetes and Prometheus, and all of their projects are cloud-agnostic, making it easy to spot projects to support your multi-cloud strategy.
