Cloud Options
MongoDB Atlas is a global cloud database service built on AWS, Azure, and Google cloud. We can deploy ,operate and scale a MongoDB database in just a few clicks. Here we will discuss on creating MongoDB in Cloud. Login to https://cloud.mongodb.com/ using google account. We can create a database using the below steps after logging to https://cloud.mongodb.com
Click on Build a Database.Choose the free option “Shared” for now
Select any of Cloud service provider, here I chose Azure.
Click on “Create Cluster”
Once the cluster is created ,in network access, add the IP entry to get access from your local desktop.
We also create database user for cluster to access cluster.
We then use MongoDB Compass to connect to the cluster.
Installing MongoDB Compass:
Download software using URL ,for windows File (mongodb-windows-x86_64-5.0.3-signed.msi) {https://www.mongodb.com/try/download/community}
Once Installed open Mongodb Compass
In the connection string paste the URL saved above.
Here we can see all the databases in the cluster
I have created a “Training” Database in below screenshot with single click as create database.
Conclusion
This process describes how we can create a cluster in ATLAS and MongoDB database in the cluster.
