Best Containers as a Service (CaaS) with a Free Trial of 2025

Google Cloud Run exemplifies the Containers as a Service (CaaS) model, providing developers with the capability to deploy and manage applications within containers while eliminating the need to oversee the underlying infrastructure. It simplifies the process of packaging applications into containers for deployment, requiring minimal effort from developers, and automatically manages scaling and load balancing. This serverless container management approach allows developers to concentrate on the essential aspects of their applications without worrying about operational tasks. New users can take advantage of $300 in free credits to explore Cloud Run, providing a practical experience of how CaaS can streamline their deployment processes. As a result, Cloud Run is an attractive option for those seeking efficient and scalable containerized solutions. With integrated security and performance features, Cloud Run delivers a comprehensive CaaS solution for contemporary application deployment.

Ambassador Edge Stack, a Kubernetes-native API Gateway, provides simplicity, security, and scalability for some of the largest Kubernetes infrastructures in the world. Ambassador Edge Stack makes it easy to secure microservices with a complete set of security functionality including automatic TLS, authentication and rate limiting. WAF integration is also available. Fine-grained access control is also possible. The API Gateway is a Kubernetes-based ingress controller that supports a wide range of protocols, including gRPC, gRPC Web, TLS termination, and traffic management controls to ensure resource availability.

You can use your favorite debugging software to locally troubleshoot your Kubernetes services. Telepresence, an open-source tool, allows you to run one service locally and connect it to a remote Kubernetes cluster. Telepresence was initially developed by Ambassador Labs, which creates open-source development tools for Kubernetes such as Ambassador and Forge. We welcome all contributions from the community. You can help us by submitting an issue, pull request or reporting a bug. Join our active Slack group to ask questions or inquire about paid support plans. Telepresence is currently under active development. Register to receive updates and announcements. You can quickly debug locally without waiting for a container to be built/push/deployed. Ability to use their favorite local tools such as debugger, IDE, etc. Ability to run large-scale programs that aren't possible locally.

Hostman is a cloud platform that scales and deploys web applications. It automates DevOps and comes with CI/CD. This saves developers a lot of time and helps businesses save money. Hostman is intuitive and easy to use. You can host static websites, back end applications, Docker containers and databases on Hostman. Scaling has never been easier. It is easy to enable and scales your application automatically within the limits that you have set. The service is free for your static website and front-end apps. It also includes a global CDN (45 full stack edge locations with 65+ Tbps throughput) and a free SSL certificate. We offer back-end services at a very simple pricing model that uses a pay per use model. Prices start at $6.50 Our service is worldwide, so your application can be hosted anywhere in the world. Your services are hosted on AWS, Google Cloud Platform and Azure.

Rapidly create applications without the hassle of overseeing virtual machines or learning unfamiliar tools—simply deploy your app in a cloud-based container. By utilizing Azure Container Instances (ACI), your attention can shift towards the creative aspects of application development instead of the underlying infrastructure management. Experience an unmatched level of simplicity and speed in deploying containers to the cloud, achievable with just one command. ACI allows for the quick provisioning of extra compute resources for high-demand workloads as needed. For instance, with the aid of the Virtual Kubelet, you can seamlessly scale your Azure Kubernetes Service (AKS) cluster to accommodate sudden traffic surges. Enjoy the robust security that virtual machines provide for your containerized applications while maintaining the lightweight efficiency of containers. ACI offers hypervisor-level isolation for each container group, ensuring that each container operates independently without kernel sharing, which enhances security and performance. This innovative approach to application deployment simplifies the process, allowing developers to focus on building exceptional software rather than getting bogged down by infrastructure concerns.

Mirantis Kubernetes Engine (formerly Docker Enterprise) gives you the power to build, run, and scale cloud native applications—the way that works for you. Increase developer efficiency and release frequency while reducing cost. Deploy Kubernetes and Swarm clusters out of the box and manage them via API, CLI, or web interface. Kubernetes, Swarm, or both Different apps—and different teams—have different container orchestration needs. Use Kubernetes, Swarm, or both depending on your specific requirements. Simplified cluster management Get up and running right out of the box—then manage clusters easily and apply updates with zero downtime using a simple web UI, CLI, or API. Integrated role-based access control (RBAC) Fine-grained security access control across your platform ensures effective separation of duties, and helps drive a security strategy built on the principle of least privilege. Identity management Easily integrate with your existing identity management solution and enable two-factor authentication to provide peace of mind that only authorized users are accessing your platform. Mirantis Kubernetes Engine works with Mirantis Container Runtime and Mirantis Secure Registry to provide security compliance.
