I've been a big fan of Google Cloud Platform from the beginning, and they aren't even paying me to say that. Many critics place GCP far enough behind AWS and Azure that most people haven't considered the "third option," but this leaves much of the story untold.
We engineers love to compare hard numbers, and the number we compare the most in the cloud space tends to be the number of services. AWS has 10 million services to date, and will always win in this category. AWS also considers SNS, SQS, and Kineses to be three separate services, as opposed to, I don't know, designing a single service that can handle those needs? Picking quality over quantity, in my personal opinion, is Google Cloud's differentiator. Google Cloud will never offer hundreds of services because it focuses on doing the things it does well, whether that be in terms of performance, ease of use, or flexibility. It's clear Google hired quality Product people where other cloud providers did not.
Spinning up a VPS is kind of like a "hello world" for gauging cloud providers. We can learn a lot about the dumb decisions (or lack thereof) embedded in a vendor's philosophy by how they chose to design the most simple task imaginable. Let's see what we've got here.
Performance Comparison
In the blue corner, weighing in at 1 CPU and 3.75 RAM, we have our challenger: Google Compute Engine. In the opposing corner, weighing in at 4GB RAM and 2 CPUs, we have the defending champion: Digital Ocean. If we were going by numbers alone, it would seem like Digital Ocean has a clear advantage of winning this matchup.
We will deploy the same site on both machines and compare their performance rankings. How will we do this? With Google's Lighthouse, of course! Now, using a Google tool to benchmark a Google product is hardly fair, but let's be honest: the load time of a site shouldn't theoretically change to any degree noticeable by humans just by changing clouds, right? Website load times are far more dependent on execution than VPS host...
Digital Ocean
Let's start with Digital Ocean, where we're hosting hackersandslackers.com. Not great, but not terrible:
Compute Engine
Here's the same site being hosted on Google Cloud, on a machine with theoretically lower specs:
Jesus! 10 points is a lot for no changes whatsoever. All other metrics stayed the same across the board, which reinforces the fact that no other aspects are at play. Ten points also seem like a suspiciously clean bump. I'm not saying the results are rigged, but it's worth asking whether or not Google silently favors its customers. If Google does in fact favor sites running on their infrastructure, what are the SEO implications of boosted ratings? Most people would pay a premium to be 10% better in the eyes of Google's algorithm, so these results are significant regardless.
Pricing
Let's do our best to see how Compute Engine pricing stacks up:
Provider | Name | # of CPUs | RAM | HD | Price / Month |
DO | Droplet | 2 | 8 | 80GB SSD | $20.00 |
AWS | t2.medium | 2 | 4 | EBS | $38.00 |
GCP | n1-standard-1 | 1 | 3.75 | 80GB SSD | $38.00 |
Azure | DS1 v2 | 1 | 3.75 | 32GB SSD | $51.10 |
Making these comparisons is challenging to do accurately. We've already seen how the quality of RAM or CPU can vary between cloud providers, so these numbers are not 1-to-1. To make matters worse, AWS considers VPS storage an utterly separate product (wow).
From what we know, this price chart actually looks pretty strong for Compute Engine. GCP machines are substantially cheaper than their equivalent Azure machines. The EC2 instances would cost more than we see listed after adding disk space, so we're essentially paying for an extra CPU.
Does in Fact Compute
Google Cloud gives us a lot of options for customizing our Compute Engine. There are two ways of selecting a machine size: by selecting from the list of preconfigured VMs, or by tweaking the specs of our machine by using the custom option.
Here are the preconfigured choices we have:
Picking from a cookie-cutter machine has a notable advantage: when we do so, we can select which CPU we want. This allows us to specify that we'd like a Skylake processor:
When customizing a machine, we have the very cool ability to select precisely the number of cores and RAM we want via some nifty sliders. The disadvantage to doing this is we lose the ability to reserve a CPU type. Thus, we almost certainly get a lower-quality CPU than we would otherwise:
OS and Boot Disk
There is no shortage of Linux distros to pick from on GCP:
The size and type of our instance's boot disk are always up to you, which is a great feature. I highly suggest taking this chance to create an instance with more than 10GB... I learned the hard way that maxing out a server's boot disk bricks your machine.
Firewall Stuff
In case you're following along, make sure you check Allow HTTP traffic and Allow HTTPS traffic before continuing (assuming you want public traffic). You could change this later, but save yourself the headache of troubleshooting this later.
Once your instance is created, you can SSH into your server via GCP's browser client to give it a spin.
Point DNS to Your Instance
Let's see what's involved in pointing a domain to Compute Engine. Edit the server you just created and go to the network interface section to add a static IP:
A massive advantage that GCP has over AWS is the ease with which we can configure important network stuff. We're able to do things like assigning IP addresses without jumping between multiple screens, configuring security groups, navigating subnets, creating CIDR blocks, or whatever. Even though all of that is possible, Google surfaces the things we want in the places we might expect them to be, like directly on our VPS edit screen.
Cloud DNS
Google handles DNS via its "product" Cloud DNS, which handles everything you'd expect to do with domain name records. To set up a domain, we need to create a DNS zone for the domain we'll be pointing to Google Cloud's nameservers:
With a DNS zone created, you can see Google's nameservers to point your domain to (look for the Registrar setup link up in the upper right-hand corner). The nameservers should look like this:
Name | Type | TTL | Data |
---|---|---|---|
memegenerator.io. | NS | 21600 | ns-cloud-b1.googledomains.com. |
ns-cloud-b2.googledomains.com. | |||
ns-cloud-b3.googledomains.com. | |||
ns-cloud-b4.googledomains.com. |
Adding DNS Records
Now we can add some DNS records! Create an A record and point it to the static external IP of your Compute Engine:
VPC & Firewall Settings
Selected Create a Firewall Rule and check out the process for setting this up:
- Targets: Each "target" refers to a GCP service to which we want to route traffic. In conjunction with "Protocols," we see the familiar
:80
and:443
ports that signify a server's HTTP and HTTPS ports, respectively. - Target service account: Referring to the above, this is where we select the computer instance we want to hit.
- Target service account scope: Select "in this project."
- Source Filter - Once again, select the specified service account.
- Source service account scope: Select "in this project."
- Source service account: This is where we say where the traffic is coming from. It's coming from the App engine, as this is where we specified our DNS.
- For IPs and ports, well, do what you want. It's your server.
Setting up a firewall rule is so straightforward that you probably missed an important fact: we did all this painlessly on a single screen. Streamlining this process can be considered an achievement when we look at the horrendously low bar set by other cloud providers regarding networking configuration. As much as I'd love to rip into AWS on this, insulting Amazon's horrendous UX almost seems distasteful at this point.
Bigger Picture
Having made these comparisons, hosting with GCP has more advantages than I expected. Compute Engine offers arguably the most competitive and transparent pricing of the three major cloud providers. We also have way more power to customize our machine as we see fit. Lastly (and perhaps most important), the GCP ecosystem offers powerful simplicity for users. We shouldn't underestimate the impact that comes with user experiences - we'd likely have fewer devastating hacks on enterprises if cloud providers were less convoluted.
GCP isn't wholly free of redundancies. As much as I love to hate AWS, it seems almost inevitable at this point that any enterprise cloud service will maintain a certain level of complex processes. This flexibility is great for enterprises scaling quickly, but let's be honest: if these platforms were easy to use, who would pay for the certifications?
Cheekiness aside, I've become a strong fan of GCP. Google seems to have hit a middle ground between being user-friendly and powerful, which fills a niché we'll realize was desperately needed. For a fair review of the platform itself, I find myself agreeing mostly with this stranger from the internet: https://www.deps.co/blog/google-cloud-platform-good-bad-ugly/
