A RELIABLE CLOUD-BASED
SAAS ARCHITECTURE
Everything in the cloud
When building a (global) SaaS application chances are high that you’re building it in the cloud. The cloud
has a lot of advantages – think of scalability – in contrast to local server environments. Here’s
how to secure a cloud-based SaaS architecture.
How to get started?
WHICH LANGUAGE?
WHICH DATABASE?
WHICH SOFTWARE?
Which programming language?
Building a product for the cloud, means building a product with a modern programming languages.
There are various (modern) programming languages out there making it a hard time to choose the right one.
Take a look at the most prominent ones, play around with those and try to experiment as much as possible.
The perfect database
Documentdatabasesgettheirtypeinformationfromthedataitself.Thereforeeveryinstanceofdatacanbedifferentfromanyother.Thismakesitmoreflexibleindealingwithchangeandoptionalvalues,mapsmoreeasilyintoprogramobjects,andoftenreducesdatabase
size.
WHY?
We recommend making use of a
document-oriented database.
MongoDB – the database for your web app?
We – at Usersnap – ended using MongoDB as our prior database. Why we choose MongoDB? Because MongoDB is a document oriented
database that provides high performance, high availability, and easy scalability.
WhyMongoDB? ScalingyourtechwithMongoDBisprettyeasy(ok,atleasteasiercomparedtootherdatabases).Withautomaticshardingyoucandistributedataacrossvariousmachines.

Again, I’d like to give you some insights on the queuing system we use, RabbitMQ. We run our web app in on the AWS EC2 where RabbitMQ can be run installed and run
super smoothly.
