In this post, I would like to sharing resources preparation for become Google Certified Associate Cloud Engineer and how getting the certification is going to help your career.
Motivation
You might be wondering: “Why even bother getting Google Cloud certified when everyone knows that AWS is the indisputable leader in the cloud race?” That is true, however, I can give you a couple of reasons. As you can see, with AWS leading and Azure catching up pretty fast, GCP is now going through a maturing phase with the biggest percent of experiments conducted and plans for future usage.
There are several reasons for this interest.
First, Google offers the most customer-friendly prices for services compared to other cloud providers, meaning that you’re paying less for the same features and benefits. And while this might not be a selling point for some businesses, if your cloud bills are expected to be huge, even a 15–20% saving is a lot of money that can be allocated elsewhere. Google also offers a handy Pricing Calculator that allows you to get a pretty accurate estimate of your future cloud expenses. It might be challenging to use for some products since you have to do a lot of estimating yourself, but for the most part, it’s a useful tool.
On top of that, GCP is designed to be more friendly toward developers. When you’re working with AWS, you might feel that you need more experience in systems administration, networking and infrastructure operations. Google is offering an easier way to bootstrap your environment and focus on your application, i.e., your business.
Lastly, big companies are looking into GCP as a potential candidate for their next project or even as a migration target. This creates a vast market GCP engineers will have to fill soon.
First Step
Now, let’s get down to business. To prove your knowledge and experience with a piece of technology, you obviously need some hands-on experience with it. And getting certified in the subject is an excellent way to get recognized for your knowledge and skills. The entry point to the Google Cloud certifications is the Associate Cloud Engineer certification. Unlike AWS, this is Google’s only associate-level certification, which means that the other ones are much harder to get as they require more in-depth knowledge and more extensive experience.
The exam I took tests your practical knowledge with GCP’s main services and is focused on day-to-day operations. Its goal is to prove that each certified engineer is actually able to roll out a solution to the cloud and support it during its lifetime according to the recommended best practices.
Exam Preparation
The main question is: how can you get the required knowledge for the exam? Having taken it just recently, I can give you a few tips.
Step 1: Check out the exam scope
Take a good look at what Google is expecting from you to pass the certification. Their official Exam Guide describes the scope in much detail. Do note, though, that not all topics are examined equally: some appear more often in the questions than others. However, the guide serves as a great reference point or a checklist for your preparation.
Step 2: Take a relevant course
My tip is to log in to Cloud Console, open up the services list, go through each of them and try to understand and remember what problems they try to solve. After that, you can cross-reference the entire list with the scope from Step 1 and see which services have to be covered more thoroughly. When you see that something isn’t clear for you, take a look into the official documentation for the service. Don’t let it scare you: Google’s docs are very well-written and are guaranteed to be up-to-date and correct.
I took the CloudGuru course on the subject, and it helped me gain some initial understanding of what’s what and where to look. The course is good, but honestly, a lot of information is missing, so you will need to read up on other services and get your hands dirty with them if you want to be 100% confident at the exam. For example, the test requires a profound knowledge of App Engine and at least understanding the use-cases for multiple storage options like Bigtable, BigQuery, Cloud Datastore, Cloud SQL, Spanner and Cloud Storage. Not all of these come up in a lot of details in the exam, but you do need to be familiar with them.
Step 3: Get practice
Google Cloud has an awesome Free Tier, especially compared to other cloud providers. They have the biggest Always Free offers and they give you free $300-worth credits you can use to try out virtually any service for 12 months. There are certain limits, but you’re not likely to encounter them even when trying out the craziest stuff. More than that, if you go over the limit, Google will not charge you unless you explicitly turn on billing for your account.
What I do recommend focusing on is App Engine since it comes up a lot. Also, take a good look at GCE since it is the most basic compute option in GCP and VPC, which you can only really grasp while trying out a couple of networking scenarios in it.
Step 4: Take the practice exam
Google provides a practice exam for the certification, and it’s very representative. The questions there are very similar to the actual ones you’re going to be asked. Take the Google Associate Cloud Engineer Exam Dumps. I recommend this site for free and paid practice version.
https://www.gcp-examquestions.com
Actual exam questions in the paid version really helpful and I’m sure you can pass with it. I feeling more confident when take the real exam. 20$ is totally worth.
Clear the exam
As to the actual exam, it was much easier than I had expected. You have 2 hours to answer 50 questions. I finished it in about 45 minutes, which left me enough time to review the answers. I was preparing for some time before that, though, about an hour a day for 2–3 weeks. I have a good preparation with exam dumps and I passed the exam in short of time.
Google tends to focus their questions on their flagship products. There are a lot of questions about App Engine and I do recommend trying it out in practice because there will be a lot of details. Questions related to Kubernetes, Cloud Storage and VPC are quite frequent too. It is a Cloud Engineer exam, so they require a lot of practical knowledge like working with gcloud SDK (you don’t really need to remember all the commands, but you have to try it out a couple of times and understand the API to be able to tell the obviously wrong answers from the more realistic ones). GCP’s Stackdriver also comes up quite a lot since it is a complex and handy tool that helps with monitoring, debugging and profiling your applications in production. As I said, GCP is made with engineers in mind, so Google wants to highlight the benefits for them in the exam.
