What is SaaS Development [Types, Benefits & Challenges]

The market for SaaS (software-as-a-service) is experiencing rapid growth. Predictions say that by the year 2030, it will grow to $908 billion. Every year, the rate at which it grows will increase from 18% to 18.7%. An increasing number of businesses are choosing the SaaS model because of its advantages in cost reduction, scalability enhancements, and improved security. But, what is SaaS development and why do your business need it?

Growing your business involves developing SaaS applications. But converting your current solution into SaaS or building one from scratch requires a good understanding of SaaS specifics, saas meaning, software as a service examples, best practices in development, and common mistakes to avoid. 

This article aims to give you a better understanding of what is SaaS development and outsourcing so that you can make the most of the technical advantages of SaaS for growing your business.

Let's tackle this simple yet important question first: What is SaaS development? 

What is SaaS Development?

SaaS, also known as  Software as a Service, is a model where software applications are hosted on the internet instead of on an organization’s internal servers. Users pay a regular subscription fee to access SaaS software through a web browser or application.

The main benefit is that users can access the application from any internet-connected device without the need for installation.

From a business perspective, SaaS development offers significant cost savings by eliminating the need to establish IT infrastructure. It streamlines software updates, allowing developers to make improvements without disrupting users. This ensures uninterrupted software usage and avoids revenue loss during updates.

Now that you learned ‘’what is saas’’, let’s learn how it works.

How Does Software-as-a-Service Work?

SaaS operates on a simple principle: instead of installing software on your own computer or company servers, you access it over the internet. 

SaaS (Software-as-a-Service) applications offer customized features accessible via web browsers and various devices over the internet, enabling businesses to address their customers' requirements efficiently. Here's how it typically works:

The subscription-based model of SaaS eliminates the need for businesses to install applications locally on their devices or invest in costly hardware upgrades. 

Let’s find out more about SaaS after learning what is SaaS application development and how it works.

Differences Between SaaS vs. IaaS vs. PaaS

SaaS, IaaS, and PaaS are three primary cloud service models where providers offer hosted data center resources to users via the internet. While all models involve cloud-based delivery, they vary in the comprehensiveness of the product.

SaaS provides complete, fully managed applications, eliminating the need for users to download software or manage IT infrastructures. Providers handle all aspects of software management, including maintenance, upgrades, support, and security.

IaaS involves outsourcing data center and computer resources to a cloud provider. Providers host infrastructure components like servers, storage, and networking hardware, but users retain control over their data use, applications, and operating systems.

PaaS offers a development platform and tools hosted by the provider, enabling organizations' in-house developers to create customized applications. While the vendor manages data center resources supporting the tools, users are responsible for managing their applications and data use.

Types of SaaS Applications

To gain insights into crafting a SaaS product that resonates with your target audience, explore the primary types of software-as-a-service available in the market.

Project Management Software: Trello and Jira are examples of platforms facilitating businesses in managing workflows and collaborating with team members through task assignments, resource allocation, and project tracking.

Customer Relationship Management (CRM) Software: It is a type of application designed to help businesses manage interactions with current and potential customers. It can store customer data, track sales activities, manage marketing campaigns, and facilitate customer support.

Salesforce, Hubspot and Zoho stand out as a notable example in this category.

You might also like:

Enterprise Resource Planning (ERP) Software: These solutions help large enterprises with managing various business processes, encompassing manufacturing, commerce, reporting, sales, supply chain, human resources, and more. 

Oracle Netsuite, Microsoft Dynamics 365, and SAP Business One are among the well-known examples.

Content Management System (CMS) SaaS: These platforms offer content management and publishing functionalities. Webflow is a great CMS SaaS.

E-Commerce Software Solutions: Online retailers rely on these products to handle product management, inventory, shipping, and taxation. BigCommerce and Shopify are great examples.

SaaS Marketing Tools: These applications help businesses with executing marketing strategies and campaigns, as well as tracking business success. They comprise analytics tools like Google Analytics, social media management platforms such as HootSuite, and SEO toolkits like SEMrush.

Vertical SaaS Tools: These solutions cater to specific industries or optimize particular business processes. Examples include Veeva for pharmaceutical management, BioIQ for MedTech, and Guidewire for insurance.

Remote Collaboration SaaS Tools : This type of SaaS applications have various solutions such as cloud storage and file-sharing applications (e.g., Google Drive), time-tracking tools (e.g., Toggl), online chats (e.g., Slack), and video conferencing tools (e.g., Google Hangouts).

SaaS Architecture

SaaS architecture is the structure of software applications delivered over the internet as services. 

SaaS services and applications typically employ a multi-tenant approach, where one instance of the application operates on the host servers, serving multiple subscribing cloud tenants or customers. This shared instance runs on a single configuration for all users.

This multi-tenant approach ensures that while all customers share the same infrastructure, each tenant's data remains secure and isolated. There are two primary implementations of this approach in SaaS development:

- Single App Instance & Database

All users access a shared database within the cloud environment. This method is straightforward but may encounter scalability issues, affecting overall performance.

- Single App & Multiple Databases

Users are directed to different databases based on capacity, allowing for better resource allocation and responsiveness. However, this approach is more resource-intensive and costly.

While multi-tenancy is the prevalent architecture in SaaS software development, other approaches like single-tenancy, horizontal SaaS, and vertical SaaS cater to specific organizational needs.

SaaS Security and Privacy

The cybersecurity risks of Software as a Service (SaaS) differ from those of traditional software, where vendors address code vulnerabilities, while users ensure secure infrastructure. 

Despite cloud-based SaaS popularity, concerns persist about security and privacy, including encryption, identity management, monitoring, incident response, integration challenges, data residency compliance, privacy, costs for third-party tools, and limited communication with experts during sales.

What are the Advantages of SaaS?

SaaS has many advantages. SaaS streamlines software deployment and management, enhances accessibility, and reduces IT burden for organizations. But how? Let’s check the benefits of SaaS: 

SaaS offers numerous benefits like accessibility, scalability, cost-effectiveness, security, seamless updates.

- Reliable Revenue Stream: Monthly subscription fees are considerably more cost-effective when compared to the expenses associated with purchasing software outright, along with acquiring additional tools. SaaS products provide a consistent income flow through their subscription-based model, enabling businesses to forecast and invest in expansion confidently.

- Reduced Initial Expenses: SaaS development eliminates the necessity for substantial investments in hardware and software infrastructure upfront. This simplifies product adoption for customers and lowers entry barriers.

- Scalability as Needed: SaaS platforms can effortlessly scale to accommodate a growing user base without significant infrastructure investments. This flexibility is particularly advantageous for startups and expanding enterprises.

- Automated Updates: SaaS providers regularly deploy updates and enhancements to all users. This ensures that your product remains up-to-date with the latest features, security enhancements, and bug fixes, eliminating the need for manual updates.

- Enhanced Security: SaaS products benefit from centrally managed hosting and frequent security updates, mitigating the risks of piracy and cyber attacks. Moreover, subscription-based access discourages unauthorized duplication as it does not grant access to the underlying product.

Issues to Consider Before Developing a SaaS Applications

The first challenge before developing a SaaS is to research the market to assess demand for your SaaS product and understand the competitive landscape. 

Clearly define the unique value proposition of your SaaS application. Identify the problem your application solves and articulate the benefits it offers to users compared to existing solutions in the market.

After that, determine how you will generate revenue from your SaaS application. Explore different monetization models such as subscription-based pricing, freemium models, or usage-based pricing, and choose the approach that aligns with your business goals and target market.

Technical feasibility and scalability is another issue to consider before developing a SaaS application. Assess the technical feasibility of your SaaS application, including the technology stack, infrastructure requirements, and scalability considerations. Ensure your application architecture is designed to handle growth and can scale efficiently to accommodate increasing user demand.

SaaS security is an important issue to consider. Prioritize security and compliance considerations to protect user data and ensure regulatory compliance. 

You should plan for ongoing support and maintenance of your SaaS application post-launch. 

For data management and privacy, you can develop a data management strategy to handle user data responsibly and comply with data privacy regulations such as GDPR or CCPA.
