In the Pursuit of Great Benefits: Single Tenant vs Multi Tenant SaaS Architecture

  • The first is a SaaS cloud application that can be hosted on one physical machine for a single customer and is called single-tenancy.
  • Another option is an app hosted in a more scalable, shared environment that supports multiple customers — multi-tenancy.

Single-Tenant Cloud Architecture

Benefits of Single-Tenant Cloud Applications

  • Exceptional reliability: SaaS built on a single tenancy is usually more robust because one instance of software serves one client. Thus, the whole system is not affected by cloud traffic and an influx of overloads and operations in real-time.
  • Superior data security: In single-tenant architectures, data centers are highly regulated, and security is considered a fundamental component of operating in these huge-scale data centers. With single tenancy, you’ll spend less time worrying about hosting security and more time working and creating.
  • Simplified migration: A single-tenant cloud architecture can be migrated and deployed in minutes, provides a single instance of an application, and in most cases, can be scaled up and resized with a few clicks. This also concerns updates: one app can also be easily updated and new features deployed overnight without impacting other applications.
  • Effortless customization: There’s a lot of maintenance and infrastructural support that goes along with running a single-tenant cloud application. The services are mostly carefully handled by the service provider you’ve chosen. Many single-tenant server providers offer their clients access to dedicated servers and gives the server registers access to clients. This would be impossible within a multi-tenant environment.
  • Effortless backup and recovery: Restoring or backing up your database is much more straightforward and more time-efficient on a single-tenant cloud app, as each of the processes happens on your own individual dedicated server. Your company can access data effortlessly and then revive the settings you had prior to backup.
  • Full control: When all your operations and data run on a dedicated part of a SaaS server, you have total control of all features, storage settings, security events, and updates to your app.

Drawbacks of Single-Tenant Cloud Applications

  • Enhanced costs: The issue with single-tenant SaaS is that hosting can be too expensive for most companies. Getting an accurate picture of the cost per customer is a critical starting point that can help companies sustain their goals. After all, it’s one of the easiest ways to identify spending.
  • Fewer deployments: With the release of updates and features for specific customers, single-tenant SaaS users may be deprived of some benefits. Feature updates and deployments are not typically released within single-tenancy because of their individual instances of the program and related components.

Multi-Tenant Cloud Architecture

Benefits of Multi-Tenant Cloud Applications

  • Lower cost: Multi-tenant cloud architecture can be used to help manage infrastructure costs. It might be especially important for startups. This type of cloud architecture gives companies a balance between financial stability and the rapid need to scale services.
  • Regular deployments: In a multi-tenant environment, all clients frequently receive important feature updates. IT leaders, in turn, have the flexibility to start a project and scale it up or down on the fly.
  • Seamless adaptation: Multi-tenant software is designed to instantly configure services, making each new client’s onboarding simple and intuitive. Clients have vast space for customizations, can easily add new users, and set up additional third-party installations themselves.
  • Optimal efficiency: To guarantee the same level of service for all clients, SaaS providers use resources that deliver optimal performance. Operating workload is hovered between customers to provide flexibility for each user.
  • Optimized supervision: Maintenance expenditures are generally included in a SaaS service purchase agreement price, eliminating the trouble of finding a specialist and paying them for their service. Frequent updates and deployments are also a part of provider-handled operations, which improves uptime and productivity.

Drawbacks of Multi-Tenant Cloud Applications

  • Increased security risk: One of the common drawbacks is that data stored in multi-tenant cloud apps can be entirely pushed outside of the user’s control. The risk of losing an important piece of data can be detrimental. In case one client’s data is leaked, this may harm other customers’ data.
  • Resource availability: Increased workload of one client can affect other clients who use the same resources in a multi-client installation. Also, as more tenants are added, the applications tend to fragment. This poses a problem because each tenant cloud application requires its own SQL database, which could cause a major resource drain for each tenant.
