MongoDB Atlas — 3 of X. Setup your MongoDB Atlas — Build Your New Cluster.

Now, let’s focus on setting up your MongoDB Atlas to ensure you’re paying zero dollars! Right?

What’s up, I’m Tyler Garrett! Let’s get started on 3~!

Robots building your MongoDB, you just guide the robots. Click, click, click. Beep boop.

Free is legit, and I’m excited to learn this with you. If you’ve missed our previous writing about MongoDB being not being that complex, you can read about it here.

Also, if you need help signing up to MongoDB Atlas, then be sure to follow along in our previous tutorial.

MongoDB Atlas — Signup to MongoDB Atlas. 2 of X

Alright, once you’ve signed up to MongoDB Atlas, you’re going to dig into the process of generating your database. But being a revolutionary tech space, they don’t call it ‘building your database.’ Rather they call it ‘Build Your New Cluster!’ I can dig it.

Build Your New Cluster on MongoDB Atlas (it’s free I promise.)

Check it out, it’s free, so when you get to this page, it selects a paid plan, just ignore that!!!

After the signup: You’re going to notice it bumps you into a screen that shows you’re paying for something... The first thought in my head was..

What the H311…

Here’s a picture of me, the saddest panda ever.
Just kidding, it’s from the intro video.

Here’s my face, 2 tutorials in, a third one on the way, and this thing just defaulted to a ‘not so free’ solution…

I thought MongoDB was free..

How am I going to explain how to do this for free…

You’re probably thinking, ‘what the heck, I thought this was free..’

Oh MongoDB is free..

It’s free, it’s free, don’t get jaded by this wonky user experience, it’s free, it’s free. Cool, scroll down and change it to free. Look at the screenshot below, it will clear that up for you. Yes, it’s free, a tiny scroll down you will see Instance Size, click on the Free version!!! Okay, I’m glad I could help with that tiny work-around. It’s my speciality.

Okay, now that you’re back in the free mode, can we get started?…

You should see 0.00/4eva!

Setting up Clusters in MongoDB Atlas.

Cluster Name — Name your cluster wisely, you cannot change this later.

You can only name your Cluster once… Probably something technical to it. I’m not scared yet.

Naming your cluster, don’t hurt yourself. Keep it simple. Numbers help people keep track of large quantities of clusters. Also, if you hit ESCAPE on accident, like I did, you can click back, and I’m not entire sure what that does just yet. Will let you know… I’m going to name it… TestyMcTesterSon.

Do I win an award? Nope. Okay, moving on.

MongoDB Version — All clusters launch with the WiredTiger™ storage engine. FYI: MongoDB 3.4 with WiredTiger™ — All M0 instances launch with this version.

Well, here we go into the technical world. This absolutely is going to drive you to ask, ‘what is WiredTiger, and what is a storage engine. This is where most users might drop, just because they have no idea what this has to do with their reporting environment. NO fear, let’s skip it. (Actually, I read about it already, so I can skip it. haha)

Uh oh, maybe skipping around isn’t working out. Time to read about what WiredTiger is all about.

Regrettably this is where MongoDB team has let this content funnel get really technical really fast.

— — — — — — — — — Just skip this part if it doesn’t click, continue below.

WiredTiger Storage Engine

Starting in MongoDB 3.0, the WiredTiger storage engine is available in the 64-bit builds.

Changed in version 3.2: The WiredTiger storage engine is the default storage engine starting in MongoDB 3.2. For existing deployments, if you do not specify the --storageEngine or the storage.engine setting, MongoDB 3.2 can automatically determine the storage engine used to create the data files in the --dbpath or storage.dbPath. See Default Storage Engine Change.

Document Level Concurrency

WiredTiger uses document-level concurrency control for write operations. As a result, multiple clients can modify different documents of a collection at the same time.

For most read and write operations, WiredTiger uses optimistic concurrency control. WiredTiger uses only intent locks at the global, database and collection levels. When the storage engine detects conflicts between two operations, one will incur a write conflict causing MongoDB to transparently retry that operation.

Some global operations, typically short lived operations involving multiple databases, still require a global “instance-wide” lock. Some other operations, such as dropping a collection, still require an exclusive database lock.

Okay back to earth, wrapping up our clusters in MongoDB Atlas.

Back to earth, let’s get this done and worry about errors later :)

Can we just get through this form quickly?

Sorry, I just assumed you wanted to read about Tiger toodle-doodler.

Keep it set to 3.4.

And know, the product is currently on version 3.6.

Thanks, but we don’t have anything setup. Give us one sec.

Cloud Provider — Choose the cloud provider for this cluster… Only one option from what I’m reading. Keep it as is.

Amazon Web Services is your only option to run the MongoDB Atlas free version.

FYI, don’t change this, or you will have to pay. So, wing it. Go go go!

Just do it, click it, confirm… & deploy… Your clusterMCclusterSons.

HAHA.

Just kidding… Get this done. I trust you.

Also, you’re not going to be able to use an email address. It doesn’t explain that here, and it will explain it when you do it wrong!

Then tell the internets you’re not a robot, click that checkbox. Okay, now you have that done.

Next steps: For the love of Peter — don’t skip this step or you’re going to be SOL when it comes to syncing anyone up with your super-so-cool-data.
