Puede que con seguridad confiar en Yahoo Pipes para descargar ETL para su aplicación?

Question

Yahoo Pipes son una opción muy interesante para el tipo de solución ETL fuera del servidor de un hombre pobre, pero sería una buena idea para construir una aplicación alrededor de una o muchas tuberías? He realmente sólo los utilizaba para cosas juguete, aquí y allá, con la única cosa que he usado más de una semana o dos de ser uno amalgamado y filtrada fuentes RSS que he enchufado en Google Reader (que ha funcionado muy bien, pero si se va fuera por un tiempo no lo haría aviso).

Por lo tanto, mi pregunta es, sería la construcción de una aplicación alrededor de Yahoo Pipes ser fiable (disponible la mayor parte del tiempo)? Lo ideal sería algo que podría depender de estar arriba del 99% del tiempo.

Parece que los Tubos Condiciones de Uso permiso de construcción de aplicaciones a su alrededor, pero no estoy familiarizado con nadie construir nada significativo de usarlos.

Answer 1

I think this is really, up to your definitions of "safely" and "most of the time".

The best place to start is the Pipes Terms of Use. In it, Yahoo makes no guarantees of uptime, and has lots of denials of liability.

What happens in your system if Pipes goes away for a while?

Section 1.F.iii clearly states that you should not rely on pipes for very critical systems:

YOU SHALL NOT: Use Yahoo! Pipes to operate nuclear facilities, life support, or other mission critical application where human life or property may be at stake. You understand that Yahoo! Pipes is not designed for such purposes and that their failure in such cases could lead to death, personal injury, or severe property or environmental damage for which Yahoo! is not responsible;

From my experience, Pipes does not have extended outages but past stability is no indicator of future stability, and Yahoo may terminate the service at any point.

I can use it "safely" since if the service goes away, I will either not miss the data, or can implement a workaround using another service in a timely manner.

Answer 2

We use Pipes to power our website http://bishop.comxa.com/ where they assist in performing 'data Intergration' (scraping is an ugly word, especially if one has permission) of job vacancy content in the entire UK.

Of course Yahoo makes no guarantees of uptime, and has lots of denials of liability.. blah blah blah and so does every other web hosting provider and many have widely different ideas about what exactly constitutes 'server uptime'. [
