Software as a Service (SaaS) and on-premise solutions are technologies that have been implemented by many companies today. Both offer different benefits, but which one is better suited for your company’s needs?
SaaS offers easy access and lower upfront costs, while on-premise provides full control over systems and data.
In this article, we will discuss the key differences between SaaS vs on premise, so you can make the right decision based on your business scale and priorities.
What is on premise computing?
On-premise computing refers to the traditional method of deploying and operating business applications using a company’s internal infrastructure and resources. This means that the software is installed and run on the company’s physical office location rather than remotely through servers.
Since the data center is located on-site, the company’s IT team has complete control over managing the security and performance of the on-premise system. With full control, businesses are free to customize the system to fit their specific needs.
Advantages of on premise infrastructure
1. Full control
With on-premise computing, companies have complete control over all aspects of their infrastructure. You can select hardware and software that match your needs, configure servers, storage, and networking, and handle security systems internally.
This level of control is crucial for businesses bound by certain regulations, as they can ensure that their infrastructure is managed according to those standards.
2. Customization
Businesses also have the flexibility to tailor the system to their operational needs. For instance, they can integrate the system with other hardware or software, modify it to support specific processes, and implement unique security measures.
This customization provides a competitive advantage by allowing companies to adapt their IT infrastructure to suit their unique business model and operational requirements.
Disadvantages of on premise infrastructure
1. High initial costs
The upfront investment for on-premise IT infrastructure can be significant. These costs cover the purchase and installation of necessary hardware (servers, storage, networking equipment), software licenses, and staffing to manage the system.
For small businesses and startups with limited budgets, these expenses can be a barrier.
2. Limited scalability
While infrastructure can be designed to support business growth, scaling it can be complex, time-consuming, and costly. Often, businesses must purchase additional hardware and software.
There may also be instances where the company needs to schedule downtime while implementing these changes.
What is SaaS?
SaaS is a cloud computing model where software is delivered over the internet as a service. Instead of installing software on individual computers or servers, users access it through a web browser.
Advantages of SaaS
1. Scalability
SaaS solutions can easily scale up or down to accommodate changing business needs. This means you can add or remove users and resources as required without significant IT infrastructure changes.
2. Flexibility
Users can access SaaS applications from anywhere with an internet connection, making it convenient for remote teams or mobile workers. Also, SaaS providers handle software updates and maintenance, ensuring that users always have access to the latest features and security patches.
This flexibility causes SaaS to typically have lower upfront costs compared to on-premise software. There are often subscription-based pricing models, making it easier to manage IT budgets.
Disadvantages of SaaS
1. Data security concerns
Although SaaS providers typically have robust security measures, there are still risks associated with storing data in the cloud. Businesses need to carefully evaluate the security practices of their SaaS providers.
2. Dependency on the provider
This means that the success and functionality of your business can be significantly impacted by the decisions, actions, and performance of the SaaS provider.
The provider has access to your sensitive data, which increases the risk of data breaches or unauthorized access. If the provider’s security measures are inadequate, your data could be compromised.
Comparison of integration: SaaS vs on premise
The process of integrating infrastructure into existing business applications is quite distinct, and each approach offers its own advantages.
1. Estimated time needed
Integrating on-premise solutions typically requires more time due to the manual setup and configuration involved. The process can be lengthy and labor-intensive, potentially taking several months to fully implement.
In contrast, SaaS solutions are generally quicker to integrate. They often come with pre-built APIs and standard interfaces that facilitate seamless connections with other systems. Although some customization may be required, the overall integration process tends to be faster.
2. Customization
On-premise solutions offer greater flexibility in terms of customization. Because the software resides locally, organizations can tailor the solution precisely to their needs through modifications and extensions. This level of customization is particularly beneficial for businesses with specialized or unique operational requirements.
SaaS solutions, while offering some degree of customization, tend to follow industry-standard configurations and best practices. Any customizations available are typically provided by the vendor and may incur additional costs.
While there is room for adjustment, the extent of customization is generally limited compared to on-premise solutions.
3. Maintenance
Maintaining on-premise solutions falls squarely on the shoulders of the organization itself. This includes managing software updates, performing routine checks, handling troubleshooting tasks, and ensuring compliance with regulatory requirements. All these responsibilities demand significant IT resource allocation and expertise.
By contrast, SaaS providers handle maintenance and updates automatically. Users receive continuous upgrades and bug fixes without needing to intervene. This reduces the burden on internal IT teams, saving time and resources that can be redirected towards strategic activities rather than day-to-day maintenance chores.
Comparison of security: SaaS vs on premise
A comparison of security aspects between the two infrastructures, along with appropriate security strategies for implementation, is provided below.
To ensure security, there are strategies that can be adopted in both infrastructures, as follows:
1. Shared responsibility model
For SaaS, this means understanding the security responsibilities of the provider and verifying that they meet industry standards such as SOC 2, HIPAA, or GDPR, depending on the organizational requirements.
Organizational teams must also take steps to ensure proper configuration and regular reviews of the SaaS vendor’s security policies and measures through a vendor risk management program.
Similarly, for on-premise infrastructure, this involves clear delineation of roles and responsibilities within the organization regarding data protection, access control, and incident response planning.
2. Network security measures
For SaaS, this entails leveraging the inherent strengths of cloud-based solutions, such as automated security updates performed by the provider. Continuous monitoring and alerting systems should be integrated to track potential issues promptly.
Multifactor authentication (MFA) is highly recommended to ensure that only authorized personnel can access the network. Furthermore, network segmentation techniques can isolate sensitive areas from the broader network, thereby reducing lateral movement opportunities for attackers.
On-premise infrastructure, meanwhile, relies heavily on manual oversight and custom-tailored security protocols. Implementing firewalls, intrusion detection systems, and regular software updates are essential. Moreover, isolating sensitive systems via strict network segmentation further minimizes the risk of breaches.
3. Identity and Access Management (IAM)
For SaaS, IAM involves managing user access and privileges within the application itself. This includes setting up granular permission structures to limit what users can see and modify.
Regular audits of access permissions are necessary to prevent accidental exposures. Using IAM tools can provide visibility into SaaS application usage and configurations, helping to enforce compliance with regulatory standards.
On-premise infrastructure takes a similar approach but with direct control over server configurations and hardware. Customizing IAM solutions to fit specific organizational needs enhances data protection.
Strict identity verification processes, akin to those employed in zero-trust models, ensure that every attempt to access systems undergoes rigorous scrutiny, regardless of origin.
