Applogic basics

[sdamron]

I am looking for some instruction on some of the basics involved in using applogic. Things like how to assign ip addresses to your appliances/applications and such to start with would be nice. Can anyone point me to such tools?

TIA.

Sdamron,

See http://doc.3tera.net/AppLogic2/WebHome.html#AnchorGridUserGuide

Also see http://doc.3tera.net/AppLogic2/AdvApplicationModel.html for an in-depth overview of the AppLogic appliance and application model.

Generally, you have the following approaches:

1. You can use the GSC5 (grid server on CentOS5) template to make VPS instances -- and treat them more or less the same way as you would treat physical servers (except that they have HA and you can order/resize them with CLI commands :). For convenience, key parameters, such as the IP settings and the root password, are exposed as properties so you can set them when provisioning the instance (http://doc.3tera.net/AppLogic2/UserOps.html#AnchorAppProvision -- part of the user guide)

2. You can use a standard template -- such as Lamp or LampX4 -- and install your own php/perl/web content. An example of how you can install Wordpress on Lamp is available elsewhere on this forum. IP settings are configured as properties on the app (the same as above; use 'app config' command in the shell or open the app configuration in the editor and go to the property tab).

3. You can build a custom template -- start from scratch or from Lamp.

In the cases 2 & 3, the public-facing IP addresses of your application are in the gateways.

If you need Internet access to/from your appliance, either connect it to a gateway (preferred) or enable its external network interface (see http://doc.3tera.net/AppLogic2/RefEditorClassEditorSimple.html#Interfaces). Gateways are not magic -- they are simply appliances in which the external interface has been enabled and have small scripts that configure their IP settings according to the property values.

Unless you are using GSC-like construct, where the whole app is in a single appliance, it is better to use the gateways to contain the Internet-accessible endpoints.
