What Are Digital Services?

With digital services provided on a subscription basis, Software as a Service has become a new sales model. Many such services have several common features:

Omnichannel support (web, mobile, etc.)

Possibility to manage the service via a special panel (interface)

Integration with third-party services to build a certain functionality

Availability of special common technical services such as the notification manager, authentication & authorization server, etc.


Alex Arabey


“Digital services can belong to entirely different industries — booking systems, online cinemas, taxis, etc. However, from the engineering angle, these SaaS solutions are rather typical, and we know them pretty well — starting from the requirements elaboration phase of your Agile project, proceeding to architecture design, and ending with successful implementation and further custom support.”

Implementation Framework
for Software-as-a-Service

To make the SaaS development process seamless and scalable, we have implemented a range of software modules and components as well as some typical architecture solutions. So when it comes to the technical part of the ongoing project, they ensure that all the requirements for scalability, maintainability, performance, and security are met. Apart from that, our SaaS developers can offer white labeling of business logic for a number of components which accelerates the SaaS project rollout and considerably reduces risks.

Technical Perspective

From the technical perspective, the Service may be defined as a set of microservices. However, the microservice architecture is not a must-have point here.

  • User & Role Management
  • Authentication & Authorization
  • Product Catalog Management
  • Tariff Management
  • Billing & Financial Reporting
  • User Registration/KYC
  • Integrated Chats
  • User Segmentation & Targeting
  • General Analytics & Reporting
  • External API/OpenAPI
  • Payment/Accounting Integration
  • Back-End Integration
  • Business Operation/User Workflow Management
  • Notification Management
  • Content Management
  • And some others...

Hosting for Digital Banking Solutions

To keep it simple, there are two main options:

On-Premises Installation

Cloud-Based Deployment

We can go over both variants for you depending on the requirements of your SaaS product. When selecting the deployment option, our developers recommend considering the following factors:

Preferable service-level
agreement (SLA)


Service scaling prognosis (increase
in the number of users or operations)

Available hardware

Planned staging configuration
and CI/CD aspects

Inhouse resources and expertise
in deployment and system support

Solution Architect

“The main advantage of this approach is using the same instance of software by different groups of clients with isolated data space. Coupled with the cloud-based distribution, this model allows achieving efficient resource distribution, fast scaling, and almost free cost of maintenance for whatever isolation level we want.”

How to Start the Implementation of a SaaS Solution

The development of a SaaS application is characterized by a range of peculiarities that any experienced SaaS developer like Qulix takes into account.

  1. General business analysis — definition of actors, main features per actor (requirements matrix)

  2. Architectural analysis — hosting options, definition of third-party components to be used in the system (it is a common practice to use some available software components instead of developing from scratch), definition of the logical architecture (microservices or other options)

  3. CX/UX design — elaboration of user interfaces, development of user journeys and wireframes

  4. MVP implementation — definition of the minimal scope to go into production and its implementation. Quite often, you may urgently need to go live, if only with the limited functionality, to collect first reviews, get feedback, and make improvements to your SaaS app.

  5. Continuous development and support

We Know How to Address Potential Challenges

What does SaaS multi-tenant architecture mean?

The concept of multi-tenancy allows using one and the same instance of the SaaS solution and its infrastructure by multiple clients. The latter share a single database and the software as such. However, other tenants cannot see your data as it is kept invisible to them and protected from unauthorized access.

Multi-tenant solutions allow developers to offer services to clients of any scale — from startups with no dedicated infrastructure to large engineering enterprises with the need to use limitless computing capabilities of the cloud.

How are users separated in the multi-tenancy arrangement?

On the client side, there are three different multi-tenancy approaches of separating users: manual selection of a tenant before authentication, automatic/manual selection of a tenant after authentication, and automatic selection of a tenant by subdomain (white labeling).

On the server side, it can be a standalone app with its own database per tenant, a shared application (or a set of microservices) with a separate database per tenant, or an application with a shared multi-tenant database. The final architecture is usually based on safety rules and the type of tenant isolation.

Security, privacy, and confidentiality requirements insist on strong boundaries and data isolation between tenants, and here we can see the efficiency of SaaS multi-tenant data architecture.

How does a SaaS application help ensure service scalability and performance?

One of the best practices for developers is to host services in the cloud. Among other things, the SaaS approach enables us to perform simple and dynamic horizontal scaling — with the increase in the load on the server, the SaaS application utilizes more capacities of the SaaS platform, and vice versa.

If your company chooses to do so using on-premises servers, your team will have to perform hardware sizing calculations and on a constant basis monitor ongoing server load, while being ready to add up capacities, i. e. buy additional hardware, if need be.

How can one ensure the service availability of a SaaS app?

Like most cloud-based services, Software-as-a-Service is hosted online, and you don't have to install any components locally. Like with any service provided in this manner, user access to the software depends on certain factors which are often outside your company's control if you compare a SaaS app to any service deployed in your own datacenter. That is why think about certain measures you can take to make the SaaS constantly available.

Your team can require information on uptime and resilience from your SaaS provider, which is of special significance for critical business services. What is more, ask your business continuity planning team to map out the consequences of downtime for your company and study alternatives. In addition, make sure that you have a valid SLA that contains an uptime guarantee covering critical SaaS services.

What about data storage location?

Study carefully where service data will be kept and do not hesitate to resort to consulting. Where is your data being stored on the SaaS platform? Does your SaaS provider present this information? Does it meet the regulatory standards required by your enterprise, e.g., SOC2 compliance, or HIPAA, or GDPR? It is vital to learn this information before you start using the service.

Like most cloud services, SaaS apps are based on cloud computing, which entails that your SaaS application will be easily scalable thanks to vast storage capabilities. In most instances, SaaS apps are handled via a comprehensive hybrid multicloud SaaS platform combining your SaaS provider's servers with those of a major provider (AWS, Microsoft Azure, etc.). Make sure you know how your SaaS partner protects its clients' data against integrity and confidentiality issues, data loss and leakage, malware, and other common issues that pertain to SaaS development.

What can be done to maintain the security of my SaaS application?

Thanks to its top hardware and software expertise, our SaaS development team understands the industry and is well aware that SaaS apps eliminate some physical security restrictions that shield on-premises data. There is a number of issues that can be encountered when we deal with cloud storage: account or service hijacking, availability, integrity, confidentiality, etc. That is why the security of your SaaS solution should be at the forefront of your enterprise's decision-making process.

Major capacities you'd better take into consideration cover the capability to perform integration with Single Sign On (SSO) providers (e.g., Okta or OneLogin). What is more, do not forget that around 90% of your company's former employees may retain access to some of their cloud accounts after changing the place of work. So take care that your SaaS solution provides automated onboarding and offboarding of accounts. Eventually, the SaaS software should at least include multi-factor authentication to guard against common cyber-attack techniques and means such as password-spraying.

What's so special about Single Sign On (SSO) for SaaS?

To put it simply, SSO takes your initial login into a system (e.g., your laptop), encrypts it to ensure security (this procedure also goes under the name tokenization), and uses this token to gain access to all other systems in an automatic mode. In this case, you don't have to submit your username and password again.

By introducing this method into your SaaS solution, you get yourself a wide range of benefits. For example, tokens automatically expire, and you can revoke them centrally. When it comes to passwords, SSO technology does not share them with third-party service providers. What is more, password standards can be complex, since users need to type in the password only once a day. Also, users cannot apply one and the same password to access several services, which diminishes the risk of a single site hack.

Do not forget about central management of authentication, which means that your JML process will be streamlined. And last but not least — cost reduction and improved productivity since you will certainly see fewer requests for forgotten passwords.

As you can see, SSO integration is one of the best practices to monitor your SaaS applications and obtain detailed and actionable insight into their usage.

Some More Tips on Software-as-a-Service Development

Just like with any other type of the development process, to build a SaaS product, you need to be aware of all its traps and pitfalls. Rest assured that our team always applies the best practices to avoid or mitigate them and delivers top SaaS applications to our clients.

Omnichannel Support

You should build your SaaS software with the omnichannel approach in mind, although this functionality may seem unnecessary to you at the initial stage. This will save you time and money in the future.

Reuse of Cloud Modules

Such platforms as Amazon Web Services or Microsoft Azure come with a range of ready-to-use technical modules that can be used in SaaS development. This is a good option to consider to speed up the project.

Quick Time-to-Market

As an experienced SaaS development company, we know that it is of essential importance to introduce changes into the production environment asap. That is why choose the project architecture and processes that allow it.

Administration Interface

No matter what, you will need an interface for the service provider, administrators, content managers, and so on. Our team advises considering these options as a must in the project backlog and include them at the MVP stage.
