The open-source program itself is free, but the hosting needs to be paid monthly, how to calculate the long-term cost
The open-source program itself is free, but the hosting needs to be paid monthly, how to check the long-term cost? Be clear about 'free': The cost saved is the program authorization fee, not the operation fee. Taking common open-source content programs as an example, when self-hosting, you need to prepare your own hosting, and the approximate range of a common shared hosting is $5-50 per month; the same type of program also has a subscription-based hosting version provided by manufacturers. The cost check should be recorded in four columns: hosting, storage and backup, environment upgrade, and labor hours.
Which item is free?
| Cost item | Open source self-hosting | Hosting platform |
|---|---|---|
| Program authorization | Usually zero | Included in the subscription |
| Hosting | Pay monthly or annually yourself | Platform bears |
| Backup and restore | Configure storage and strategy yourself | Most are included in the high position |
| Upgrade of operating environment | Self-manage version and dependency management | Platform responsible |
| Man-hours | All fall on the team | 明显减少 |
The first line is the most easily misunderstood: free authorization does not mean the total cost is zero. What really drives up the cost is the last four lines, especially the operating environment and man-hours. Taking content management as an example, for a site with moderate traffic, the difference between the host and backup is usually only tens to hundreds of dollars a year, but a wrong upgrade or a version update without backup, the cost of rework may be higher.
Monthly payment invoice list
Self-hosted items listed by month or year include: host or cloud server instance, object storage or additional disk (for backups and attachments), certificate and email delivery services (as needed), as well as operation and maintenance tools. Pay attention to the renewal rules in the host billing: promotional prices usually only cover the initial billing period, and the renewal tiers and feature restrictions may change at the same time. Also note when listing, some items are charged by usage rather than by tier, and traffic peaks in certain months may cause jumps.
This item is easily overlooked and it is usually too late to make up for it when a problem occurs. The backup should cover both database and static file content, and it should be able to recover separately. The plan that only backs up the database is not helpful when the attachment is lost. The renewal rules in the host invoice should be looked at separately: promotional prices usually only cover the first billing cycle, and the renewal tiers and functional limitations may change at the same time.
Estimate resource tier based on access volume
First, look at two observable indicators: resident memory and single-machine carrying capacity. The content management system of the Go technology stack is usually more efficient in these two aspects than traditional PHP programs, the official figure is that memory usage is reduced by about 80%, and the single-machine carrying capacity is about 5 million PV, which is an important basis for estimating the host level when selecting, but note that it is an approximate figure given by the official, not a specific commitment to your site.
The practical sequence for estimating the level:
- Select a low configuration first based on the average daily visits and peak factor, and record the resident memory and response time.
- Press a peak scenario, such as list page and search page concurrent, to see if memory and response are still in the safe area.
- Then decide whether to add a cache layer or an independent database instance, adding a layer is often cheaper than upgrading the whole level.
For sites with high staticization, the level can be compressed lower than expected; for sites with many dynamic queries and plugins, the opposite is true.
The practice of cost deflection across multiple sites.
Managing multiple sites with the same program is a direct way to reduce unit costs through self-hosting: one running environment, one backup strategy covering multiple sites, and the marginal cost of adding a new domain is mainly storage and traffic. The confirmation is whether the system's multi-site capability truly shares the background and permission system, rather than deploying separately for each site - the latter saves no operational environment costs.
AnQiCMS supports managing multiple independent sites within a single backend, with配套 Baota panel or Docker image as two common deployment methods, the default listening port is fixed, convenient for one-time configuration in the host security group; the difference in deployment methods will directly affect the man-hours spent on environmental maintenance each month.
Common questions
Can I buy the minimum configuration host first?Yes, but you need to test the resident memory and peak response before deciding whether to upgrade, the risk of the minimum configuration is not in the price, but in the man-hours of migration in the middle.
How to choose between hosting and self-hosting?Answer: It depends on human resources. If someone can handle the upgrade and backup recovery of the running environment, the cost of self-hosting is lower; when no one takes over, the subscription fee for the hosting version is actually buying operation and maintenance.
Question: How many backups should be kept?Answer: At least one locally and one remotely, and keep one historical version that can be rolled back; only keeping the latest one is equivalent to having no rollback capability.
