Hébergement

L’hébergement est une condition sine qua non pour publier des données publiques ouvertes sur opendata.swiss. La responsabilité de l’hébergement incombe aux fournisseurs de données.Nous avons résumé ci-après les principales questions et réponses ayant trait à l’hébergement de données. Elles ne sont pour l’heure disponibles qu’en anglais.

Intro

In order for you to import data to the opendata.swiss catalog, the data must be freely accessible somewhere. Only the metadata and a link to the data are published on opendata.swiss. Responsibility for actual data hosting lies with the data supplier.

Data hosting is now relatively cheap and simple to manage, even if you do not yet have a solution in place within your organization. However, there are some issues you should consider before publication:

Cloud vs. data center?

Here we refer to the way your content is serviced on the Internet. In a data center, your organization would typically be responsible for running a « full stack », or entire collection, of applications required for web hosting. This means providing support for DNS, HTTP, SMTP and other critical protocols using specialized « server » programs. You often have the ability to decide on each of these components and pick the best combination. In a cloud environment, there is sometimes considerably less flexibility, however by centralizing administration and maintenance, the overall costs per site can be much lower.

How accessible are backups?

Preparing for disasters, and ensuring that data does not get lost during updates or changes, are extremely important tasks in setting up for long-term hosting. Ensure that you know how to get duplicates of your data, which are ideally being versioned for selective restoration, find out how much time and effort this process takes - and test it in advance, to be calm and prepared for any eventuality.

Are there bandwidth restrictions?

As every smartphone user knows, access to data comes at a cost. Whether it is uploading large datasets, or potentially being restricted from sharing your data to a large number of users, check with your hosting provider on what are the financial and technical aspects of this question. For instance, some providers can put special measures in place to « scale up » the rate at which your content is being distributed ahead of a marketing campaign or publicity - ensuring that none of your visitors get to see error messages or outages.

Is there a redundancy measure in place?

Redundancy is the concept of having alternative copies of the same information. In the case of web hosting, this often means having multiple servers in multiple locations provisioning the exact same content. This is useful for maximing performance across the world, or having a « safe failover » - in case one of the copies (for example, of an e-commerce web site) is for some reason inaccessible, one of the others immediately/automatically take over, and no business is lost.
