I'm really new with this technology, and I can't found information regarding this.
I'm trying to migrate a cluster solution to google compute engine, creating 4 webservers with a loadbancer.
I was thinking to use haproxy and keepalived, but is this possible? can I request a VIP?
I didn't see the option to request a VIP.
Thank you
You can reserve an IP address, and then add it to an instance when you launch it.
In GCE, those are called "Reserved IP Addresses", the documentation shows how you reserve them and assign them.

I'm currently monitoring several routers I have in my network with Zabbix 3.4.4. I'm now adding them manually but I'd like to use the discovery feature to do this automatically. The problem I have is that I need to monitor only the router, and not all other hosts on the net.
For example: I have a discovery rule for 10.0.0.0/16, I add a new network 10.0.10.0/24 which has several hosts, but I want to monitor only 10.0.10.1. Sadly being routers and from different manufacturers I cannot test services or responses, I can rely on ping only.
From what I see in the Action options there's no way to filter for such option, am I right? Is there any other way to filter hosts IPs so that I can add Zabbix monitoring only to router's IPs?
It seems like the benefit of repeatedly scanning the whole subnet just to find a small number of hosts is just not there. I'd suggest looking into creating those hosts via API instead.
Having said that, a range of 10.0.0-255.1 might work, and also reduce your network traffic significantly.
I want to host two website which one is using main domain and another one is using subdomain.
I would like to know how many instance should I purchase in order to host two of the website as mentioned above.
It always depends on the workload and host specifications.
If you have a static website then i will suggest you to use Google App Engine instead of Google Compute Engine. No doubt in compute engine you have more control over components but you have responsibility to keep things running. In contrast, Google App Engine manages the system for you. So if you have no idea about workload and managment of VM's then you should go with Google App Engine.
For some reason I see under "Operations" in my "Compute Engine" the following:
I would like to know/understand why this is happening. What is this gae-default-* VM (assuming these are actually VMs)? What are they doing actually?
If you know a lot of stuff about GAE and the Compute Engine please consider taking a look at this question "Deploying a GWT application to Google Compute Engine - What is happening here?" as well.
The CPU is getting utilized as well even though there can't be anything that runs:
If I manually delete those VMs they simply re-appear.
GAE stands for Google App Engine. Looks like you have some App Engine jobs configured. If you use the flexible version then it would manage GCE instances on your behalf. I would imagine you should be able to find the running jobs in the web console.
I assume the support for NAT is already available with the routing and networking available in compute engine? Looking for some easy to read documentation and commands to setup a situation where either one instance acts as a router and other instances can use that to access the public internet. Another scenario I'm looking for is how to make instances with no external IP address be able to access the internet. Is there a gcutil friendly way of scripting this up?
It sounds like you're looking for the Routes Collection. For your first case, the examples should show you how one instance can act as a gateway for other instances by setting a route for the internal nodes to use the gateway as a "next hop" for their traffic.
For your second scenario, there is a caveat listed that "Currently, any packets sent to the Internet must be sent by an instance that has an external IP address. If you create a route that sends packets to the Internet from a particular instance, that instance must also have an external IP. If you create a route that sends packets to the Internet gateway, but the source instance doesn't have an external IP address, the packet will be dropped."
how do I add a NIC to a compute engine instance? I need more then one NIC so I can build out an environment...I've looked all over and there is nothing on how to do it...
I know it's probably some API call through the SDK, but I have no idea, and I can't find anything on it.
EDIT:
It's the rhel6 image. figured I should clarify.
The question is probably old and a lot has changed since. Now it's definitely possible to add more nics to an instance but only at creation time (you can find a networking tab on the create instance page on the portal - corresponding rest api exists too). Each nic has to connect to a different virtual network, so you need to create more before creating the instance (if you don't have already).
Do you need an external address or an internal address? If external, you can use gcutil to add an IP address to an existing instance. If internal, you can configure a static network address on the instance, and add a route entry to send traffic for that address to that instance.
I was looking for similiar thing (to have a VM which runs Apache and nginx simultaneously on different IPs), but it seems like although you can have multiple networks (up to 5) in a project and each network can belong to multiple instances, you can not have more than one network per instance. From the documentation:
A project can contain multiple networks and each network can have multiple instances attached to it. [...] A network belongs to only one project and each instance can only belong to one network.
