Creating a Compute Engine instance

Google Compute Engine instance is just a fancy word for VPS.

Go to https://cloud.google.com/ and click "Go to Console"

Register if you didn't already - you will need gmail and a valid credit card information (look below in #Important section for more info on when you will get charged.)

You will be redirected to https://console.cloud.google.com/

Click navigation menu -> Compute Engine

Google Cloud Dashboard

Compute Engine

Click CREATE INSTANCE

Compute Engine

You will be moved to this screen:

Compute Engine

Here you can select all the options for your compute instance.

Currently (November 2019) when you register you will get 300$ of credit that last for 1 year + always free tier.

You will always have free tier available! It is a separate offer! Not to be confused with 300$ offer!

Important (ye this is very important, people are confused about this all the time):

When you register, your account is on a trial period (1 year) and cannot be charged. You need to update to PAID account in order for your credit card to be charged. Currently only thing that's going to be charged are your free credits. If your credits reach 0$ your service is stopped because Google can't charge you until you upgrade to paid account.

Credits last more that 1 year, it's just that after 1 year you can't use them anymore until you upgrade to PAID account, remaining credits don't disappear and you can still use what's remained of them after you upgrade to PAID account.

1 year 300$ offer and Always free tier are 2 separate offers. You can use always free tier , as it sais, always! Even after 1 year! You can use always free tier alongside free trial offer without deducting your trial credits (as long as your always free tier products don't exceed their limits as described in https://cloud.google.com/free/docs/gcp-free-tier). If they do exceed them then the charge is deducted from your credits.

Setting up always free tier

In this tutorial we'll cover how to set up a free VPS like service using Google Compute Engine.

So far we've gotten to the part where we're creating a compute instance, these are the options for always free tier:

Compute Engine

Currently, if you look at this google link under "Always Free usage limits" subsection "Compute Engine" it's stated that only these regions are available for your always free tier:

Oregon: us-west1
Iowa: us-central1
South Carolina: us-east1

That's why I selected us-central1 even tho I'm from Europe.

Under machine type I've selected f1-micro which is the only one available for the always free tier.

It has 1 vCPU core (you get 20% of available computing power of that core with few seconds of "bursts" meaning it can go over 20% for a few seconds) and it has 614MB of RAM.

You can select any OS, I've selected newest Debian.

HDD cannot exceed 30gb as stated in always free usage limits - I've selected 10GB as it's enough for me.

If you've selected everything in accordance with always free usage limits you will get a message on the right, under your credit balance, saying Your first 722 hours of f1-micro instance usage are free this month.

As you see in my image above it sais that its estimated cost is 4.28$ monthly or 0.006$ hourly, but we're getting it for free for first 722h of the month (that covers entire month). If we exceed 722h usage per month we will be deducted 0.006$ hourly (we can exceed 722h only if we're using 2 or more f1-micro instances at the same time).

You can leave all the other options to their default values - you can always change them later if you need them. Click "Create" button at the bottom:

Compute Engine

We have created our own, completely free, compute instance:

Compute Engine

Note the "External IP" - it is used for connecting to your VPS (SSH, SFTP etc..).

Connecting to Google compute instance using SSH

We're gonna use program Bitvise as it's much powerful than rudimental Putty.

In order to connect to our instance we're gonna need to create a SSH key.

Start up Bitvise and click "New profile":

Compute Engine

Under "Server" section "Host" we put our "External IP" which we can find in our instances window and "Port" is 22 aka the default port for SSH connections:

Compute Engine

Compute Engine

Now we can create SSH key right from Bitvise, click "Client key manager":

Compute Engine

Click "Generate new"

Compute Engine

You don't have to put comment nor do you have to put password (only if you wish), click "Generate":

Compute Engine

You can see it's been generated under "Profile 1":

Compute Engine

We need to export it so click "Export"

Compute Engine

Select "Export public key" and "OpenSHH format" then click "Export" and save it somewhere where you can easily find it:

Compute Engine

Open the saved file using notepad:

Compute Engine

Copy the entire text:

Compute Engine

Now go to your compute instances window and click "Metadata":

Compute Engine

Click "SSH keys" and then "Edit" that's right under it:

Compute Engine

Click "Add item"

Compute Engine

Paste the key we copied from notepad into opened field:

Compute Engine

It will warn you that the format is not correct. All you need to do is add either your username or email at the end (username is the part before @ in email):

Compute Engine

Click "Save", now go to Bitvise and under "Authentication" change:

The username you just entered in your SSH key (or email)

Initial method: Public key

Client key: Profile 1 (the one we created previously and copy pasted to Google SHH keys)

Compute Engine

After you click "Log in" it's done, now you can use terminal console, SFTP etc
