To host a web application, prepare its build and configuration, deploy it to infrastructure that supports its runtime, verify a preview, and then publish it to a production URL. To use your own domain, point the DNS records specified by your host to the app and configure HTTPS. The exact steps depend on whether your app is static or server-run, and whether it needs a database, APIs, or background jobs.
1. Identify what your app needs
Before choosing a host, write down the details needed to build, run, and operate the application. A static front end and an app that executes server-side code do not necessarily need the same hosting capabilities.
- Framework and runtime, including the version your app requires.
- Build command, expected build output, and start command, if applicable.
- Environment variables and secrets needed in production.
- Backend or API requirements, database, and any required data migrations.
- Background jobs, scheduled tasks, or other processes that must run alongside the app.
Use the host’s current runtime and configuration documentation to confirm that it can run the app as built, rather than assuming that support for a framework covers every feature your project uses.
2. Choose a hosting approach
Hosting makes the built or running application available through infrastructure that you manage or a provider operates for you. Managed platforms can take on much of the runtime and deployment work. A cloud architecture assembled from services can give you more control, but may require you to configure additional components such as DNS, load balancing, security controls, caching, and a managed database. AWS describes these as possible parts of a cloud architecture in its web application hosting best practices.

| Approach | Useful when | What to compare |
|---|---|---|
| Managed application platform | You want a provider to manage much of the application runtime and deployment infrastructure. | Runtime support, preview and rollback workflow, scaling, logs, database integrations, cost, and vendor lock-in. |
| Front-end deployment platform | Your app fits the platform’s supported front-end and serverless or runtime model. | Framework support, functions and APIs, build behavior, domain handling, limits, and cost. |
| Cloud infrastructure assembled from services | You need more control over network, compute, data, or architecture. | Operations burden, security design, scaling, database, DNS, monitoring, and cost. |
For examples of differing managed workflows, Azure App Service describes managed hosting for web apps; Vercel and Netlify document platform deployment workflows; and AWS Elastic Beanstalk offers an environment-based option within AWS. These approaches are not feature-equivalent, and no one provider is right for every app.
Compare support for your framework and runtime, server-side behavior, data and background-job needs, deployment method, preview and rollback options, region, scaling, observability, backups, access controls, and current price and quotas. The cited material does not establish an apples-to-apples price comparison or a definitive provider ranking, so check each provider’s live plan and runtime documentation before committing.
3. Prepare configuration and secrets
Configure production settings using the host’s environment-variable or secret-management mechanism. Do not put production secrets in public source files. Check the provider’s current instructions for how to supply configuration; there is no single method that applies across hosts.
Before deployment, confirm that the build produces the expected output, the app starts with the configured command, and the application can reach its database and APIs. If a schema change is required, plan and run the migration using the host’s documented deployment process.
4. Deploy a preview and verify it
Use a preview or staging deployment before making a version public. Test the application at the preview URL: check that routes render, forms and APIs work, authentication behaves as expected, and logs do not show blocking errors.
Vercel’s CLI documentation describes deploying a preview, checking it with a request, inspecting error logs, and then deploying to production. The particular commands and workflow depend on your provider and project setup; follow the current instructions for your host.
5. Deploy the tested version to production
Promote the version you tested or use your provider’s production deployment flow. For Vercel CLI, the documented production command is vercel deploy --prod; Vercel says that deployment is assigned to the production domain automatically. This is a Vercel-specific command, not a general web-app deployment command. See the Vercel CLI deployment guide for its workflow.
For AWS Elastic Beanstalk, the documented process is to create an application and environment, then deploy an application version. Its example notes that if no version is selected when creating the environment, a sample application can be deployed by default. Review the current Elastic Beanstalk deployment instructions to ensure you publish your intended version.

Add the domain in your hosting platform, then create the DNS record or records that the platform specifies. The required record and target depend on the provider and setup. For example, AWS’s Elastic Beanstalk guidance describes an environment URL under elasticbeanstalk.com and a CNAME pointing to the environment load balancer. Azure, Vercel, and Netlify each document their own domain setup:
Rank #4
- AWS Elastic Beanstalk custom domains
- Azure App Service custom domains
- Adding a domain to Vercel
- Configuring domains on Netlify
Use the values shown for your app in your provider’s instructions. Do not copy a DNS target from another provider’s example; a record that works for one setup may point elsewhere in another.

Configure a certificate for the custom domain using the host’s supported procedure, then open the app at its HTTPS address and check that pages and application features work. If the host does not automatically redirect HTTP traffic to HTTPS, enable the appropriate redirect for your setup and test it.
Requirements are platform-specific. For example, Azure’s documented certificate-binding procedure lists domain mapping and a supported pricing tier among its prerequisites; consult its current certificate-binding instructions. Microsoft’s documentation has also noted changes to App Service Managed Certificates effective July 28, 2025, so check the current terms if you intend to use that option. Azure’s security guidance says HTTPS-only behavior must be explicitly enabled in the described configuration; see App Service security guidance.

Do not apply that example to every Elastic Beanstalk environment; check the load-balancer type and the current AWS redirection instructions for your setup.
8. Monitor and maintain the app
Once the app is live, use the monitoring and recovery controls available for your host and plan. Check the following on an ongoing basis:
- Application and deployment logs, error rates, and uptime.
- Resource use and scaling behavior as traffic changes.
- Backups and whether you can restore data and service.
- Dependency updates, access permissions, and secure deployment practices.
- Certificate validity and renewal status.
These controls vary by host and plan. Azure’s security guidance, for example, covers diagnostics, security review, backup and recovery, and secure deployment practices; use the equivalent current documentation for the platform you selected.
