What is SaaS?
Think of SaaS as a buffet of software options. SaaS is ideal since one only pays for what is used, there is no need to buy the entire package. There is no longer a need to be concerned about license costs or installation procedures allowing you to use any number of applications and services as you choose.
One of the amazing technological advances developed is Software as a Service for instance, which allows you to access on-demand web-based applications. With SaaS, you can get a wide variety of software applications for your personal use, as well as service and license requirements.
In fact, from running a simple email to any project management and human resources (HR) and customer relationship management (CRM), SaaS does it all for you. Due to these features SaaS has become increasingly popular.
SaaS Architecture
If you’re not in the know, SaaS stands for Software as a Service, which makes all of their applications accessible via the internet. But, do you know what needs to happen to make that possible? Most likely not, and that is why this post is a necessity.
Imagine SaaS architecture as a copy for some amazing software to be able to be delivered. Just how a recipe works, it has its own ingredients – which, when combined in a certain way, creates a dish. These ingredients for SaaS are made from combinations of servers, and storage, alongside databases and networks. The provider is the one that takes care of all of the ingredients and makes sure they’re all incorporated and cooked correctly. All that is left to do is assume your role and login and use these software applications.
Technically speaking, SaaS architecture is built on a multi-tier model, which includes:
- Front-end tier: This tier is responsible for the user interface and the delivery of the commands from the user. HTML, CSS and JavaScript are mostly used in this tier
- Application tier: This tier caters for the business logic and does data manipulation. It is usually realized through the use of different programming languages and some associated frameworks.
- Database tier: This tier is designed to persist and retrieve information. It is usually done through the use of relational database management system (RDBMS), NoSQL databases or both.
The three tiers are seamlessly integrated and run on the SaaS provider’s servers, and they exchange information over the internet using standard protocols, like HTTP and HTTPS. As a result, users can run the software on various devices including mobile phones and touch screen devices via a simple web browser.
A SaaS architecture is said to be resilient and highly available with stringent security measures. Load balancing and caching methods are used by the provider in order to facilitate increased site traffic. Security protocols such as encryption and firewalls are implemented by the provider to safeguard the information kept in the database tier.

| IaaS | PaaS | SaaS |
| Functions as a primary means of computing resources such as a server, or a storage network. | Is classified as a platform used for developing, testing, and deploying various applications. | Delivered as applications that can be used over the Internet seamlessly. |
| Has unlimited ownership over the infrastructure and assets. | Has authority over the platform pre-installed and the applications deployed on that platform. | Has minimal control over the software as there is no responsibility for maintenance and upgrades. |
| Examples: Amazon Web Services, Microsoft Azure | Examples: Heroku, Google App Engine | Examples: Salesforce, Microsoft Office 365 |
| IaaS gives you the flexibility to grow your technology infrastructure at your own pace. | PaaS is the go-to solution for developers who are building software or applications. | SaaS gives you a subscription-based system that comes with a fixed, monthly fee. |
