Unlock the Cloud: What is SaaS & Why You Need It

Imagine a time when using a software program meant physically going to a store, purchasing a box with CDs or DVDs containing the software, and then installing it on your computer. Not too long ago, this was standard practice. Thankfully, today we have a more convenient way to access software: Software as a Service (SaaS). Think of it as software that lives on the internet, accessible from any device with a web browser, just like your favourite social media platform or online bank. This is the core idea behind SaaS – software delivered as an online service, eliminating the need for physical installations or downloads.

How Does SaaS Work?

SaaS applications are like high-rise apartment buildings for software. Imagine a massive data center operated by a company like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform, These data centers act as the foundation, housing the powerful servers, storage, and security systems that keep the software running smoothly. SaaS applications reside within these data centers, each occupying its own secure virtual space. This virtual space is analogous to an apartment unit within the building.

Users access SaaS applications through a web browser or a mobile app, similar to how you might enter your apartment through the building’s main entrance. This provides a familiar and user-friendly way to interact with the software, regardless of the operating system or device being used. SaaS applications also leverage a concept called multi-tenancy, which means that a single instance of the software can serve multiple users or organizations, just like a single apartment building can house many residents. Each user’s data is securely isolated within their virtual space, ensuring privacy and data integrity, similar to how each apartment unit in a building has its own locks and security features.

Benefits of SaaS

Ease of Use and Accessibility: SaaS applications are designed to be user-friendly, with intuitive interfaces and minimal setup required. No more struggling with complex installations or compatibility issues. As long as you have a device with an internet connection and a web browser, you can be up and running in minutes. This makes SaaS a perfect solution for individuals and businesses of all technical skill levels.

Automatic Updates: Unlike traditional software that requires manual updates, SaaS applications are automatically updated by the provider.By doing this, users are guaranteed constant access to the newest security patches, bug fixes and features. You never have to worry about missing out on important improvements or falling victim to known vulnerabilities.

Scalability: SaaS offers unmatched scalability. As your business grows or your individual needs change, you can easily adjust your service level to meet those demands. Many SaaS providers offer tiered subscription plans that allow you to add more users, storage space, or features with a simple click. This gets rid of the need to pay a lot of money up front for hardware upgrades and software licensing.

Cost-Effectiveness: SaaS can be a much more cost-effective solution compared to traditional software licenses and maintenance. With SaaS, you typically pay a monthly or annual subscription fee that covers everything, including software access, updates, security, and often even customer support. There are no upfront licensing costs, and you don’t need to invest in additional hardware or IT staff to manage the software. For companies of all sizes, this can result in considerable savings.

Examples of SaaS

Productivity (Gmail, Dropbox, Google Docs): This trio from Google allows you to create and edit documents, spreadsheets, and presentations collaboratively online. Store your files securely in the cloud with Dropbox and access them from any device. Communicate and manage your email efficiently with Gmail.

Communication & Collaboration (Slack, Zoom): Streamline communication within your team or with clients using Slack’s chat channels and video conferencing. Host online meetings, webinars, and video conferences for remote teams or a geographically dispersed audience with Zoom.

Customer Relationship Management (Salesforce, Zendesk): These CRM platforms help businesses manage customer interactions and data. Salesforce is a powerful tool for sales teams to track leads, manage opportunities, and close deals. Zendesk provides a comprehensive solution for customer support, allowing businesses to respond to inquiries efficiently through multiple channels.

E-commerce (Shopify): This user-friendly platform empowers anyone to set up their own online store and start selling products online. Shopify provides all the tools you need to manage your inventory, process payments, and ship your products to customers.

Subscription Model

SaaS is typically accessed through a subscription model, similar to how you might pay for a streaming service or gym membership. Instead of a one-time upfront cost, you pay a recurring fee, usually monthly or annually, to access the software. This fee gives you access to a specific set of features and functionalities within the application.

Many SaaS providers offer different subscription tiers with varying price points. These tiers cater to different needs and budgets. For example, a basic plan might be ideal for individual users or small teams, offering limited storage space or user accounts. On the other hand, a higher-tier plan might be designed for larger organizations, providing access to all features and functionalities, allowing for a larger number of users, and offering additional benefits like priority customer support. This flexibility allows you to choose the plan that best suits your requirements without having to pay for features you don’t need.

In essence, the subscription model allows SaaS vendors to continually develop and improve their software without requiring users to pay for each update. By doing this, users are guaranteed constant access to the newest features and bug patches. Additionally, subscription fees provide a recurring revenue stream for SaaS companies, allowing them to invest in ongoing development and maintenance of the software.

The Future of SaaS

SaaS is experiencing explosive growth, fundamentally changing how businesses of all sizes acquire and use software. Analysts predict that SaaS will continue to dominate software delivery, with estimates suggesting a market size exceeding $1 trillion by 2025. Numerous factors are driving this growth, including:

The increasing adoption of cloud computing: Cloud computing provides the foundation for SaaS applications, offering on-demand access to computing resources and storage. As cloud infrastructure becomes more affordable and reliable, it further paves the way for SaaS adoption.

The growing need for mobility: Today’s workforce is increasingly mobile, demanding access to applications from anywhere, anytime. SaaS applications, accessible from any device with an internet connection, perfectly meet this need.

The rise of artificial intelligence (AI) and machine learning (ML): SaaS providers are increasingly integrating AI and ML into their offerings, making them more intelligent and user-friendly. This allows for features like automated tasks, personalized recommendations, and data-driven insights, further enhancing the value proposition of SaaS solutions.


SaaS offers a user-friendly and cost-effective way to access software, eliminating the need for complex installations and ongoing maintenance. Subscription plans allow you to choose the features you need and scale up or down as your business grows. Additionally, SaaS applications are constantly updated with the latest features and security patches, ensuring you’re always working with the best possible software.

While SaaS offers many advantages, it’s important to consider a few potential drawbacks. Because SaaS applications reside on remote servers, a reliable internet connection is essential for uninterrupted use. Also, some SaaS solutions may have limitations on data storage or customization compared to traditional software that you install on your own computer. However, for most users, the convenience and scalability of SaaS far outweigh these limitations.
