Why use container hosting for Docker workloads?

Choose container hosting when you want consistent Docker deployment and scaling without taking on the server and cluster work yourself. On Caasify, you can deploy from an image or Dockerfile while the platform handles networking, TLS, logs, and scaling.

How is container hosting different from a VPS?

A VPS gives you a full virtual machine with root access and a dedicated OS. Container hosting is a better fit when you want to manage the image, configuration, and app behavior without taking on the underlying server. Choose VPS when you need OS-level control, custom system packages, or a broader machine-level setup.

How does billing work?

You are billed per second for the resources your container actually consumes. Lower-traffic apps can stay lean with scale-to-zero, while heavier database, storage, and outbound traffic needs are priced by the resources they use. There are no fixed plans, no minimum commitments, and no monthly subscriptions.

What does 'usage-only billing' mean?

Usage-only billing means you pay for the CPU and RAM your container actually uses, not the amount you allocate. If you allocate 4 GB of RAM but your app only uses 1.5 GB, you are billed for 1.5 GB. When your container scales to zero, CPU and RAM billing stops entirely.

What is scale-to-zero?

Scale-to-zero means your container shuts down automatically when it receives no traffic. While at zero, you are not billed for CPU or RAM. When a new request arrives, your container starts back up automatically. This is ideal for dev/staging environments, webhooks, and low-traffic APIs.

Which container registries are supported?

Caasify supports Docker Hub, GitHub Container Registry (GHCR), GitLab Container Registry, and any private registry that uses standard Docker authentication. You can also build directly from a Dockerfile in a connected Git repository.

Can I deploy a prebuilt Docker image or build from a Dockerfile?

Yes. You can deploy images from Docker Hub, GHCR, GitLab Container Registry, or a private registry. You can also connect a Git repository and build directly from a Dockerfile before deployment.

Can I use Docker hosting to run a website, API, or worker?

Yes. Container hosting is a strong fit for public web apps, internal APIs, background workers, cron-style jobs, and stateful services packaged as Docker containers. On Caasify, your team stays focused on the image and app behavior while the platform handles networking, TLS, logs, scaling controls, and health checks.

What storage options should I evaluate?

Look for storage that matches your workload, especially if you run databases, uploads, backups, or other stateful services. On Caasify, you can attach NVMe SSD persistent volumes to containers, and pair workloads with object storage for backups, media, and static assets.

Do I need Kubernetes to run production containers on Caasify?

No. Caasify is managed container hosting. You deploy a Docker image or Dockerfile, choose CPU, RAM, storage, and scaling settings, and manage your application instead of cluster infrastructure.

How do custom domains work?

Every container receives an auto-generated domain (yourapp.caasify.app) with TLS immediately on deployment. You can add one or more custom domains at any time — we handle DNS verification and TLS certificate provisioning automatically.

How does auto-scaling work?

Caasify monitors your container's CPU and memory usage in real time. When demand increases, additional replicas are created automatically. When demand drops, replicas are removed — down to zero if scale-to-zero is enabled. You can set minimum and maximum replica counts to control scaling behavior.

Is there a backup service?

Yes. Automatic backups are included for all persistent volumes. Backups run on a regular schedule and you can trigger manual backups or restore to a previous point in time from the dashboard.

How do I migrate from Railway, Render, or Heroku?

If your app already runs in a Docker container, migration is straightforward. Push your existing image to the Caasify registry, configure your resource settings, and deploy. Environment variables, volumes, and custom domains can be configured from the dashboard or CLI. Most migrations take less than 15 minutes.

What regions are available?

Caasify offers container hosting in 20+ regions across Europe, North America, and Asia-Pacific. You select your region at deployment time. Multi-region deployments are supported for latency-sensitive workloads.

What should I look for in a container hosting provider?

Look for a deployment path your team can maintain, clear pricing, scaling controls, storage options, and a hosting model that matches your workload complexity.

What monitoring and logging is included?

Every container includes real-time CPU, RAM, and network metrics plus centralized log streaming — accessible from the dashboard and API. No external monitoring tools are required and there is no additional charge.
