SaaS & Cloud Solutions For Business

Middleware: SOA, SaaS, Web Services & APIs

For nearly 2 decades, SPG have been developing for our clients a plethora of applications with the service-oriented architecture (SOA). This includes API-based services, middleware components, web services and Software-as-a-Service (SaaS) systems. Software Planet Group’s experience covers all aspects of SaaS development (design, build, configuration, deployment, monitoring and support). Where reasonable, we also make use of the microservices architecture (MSA), as it enables the creation of cutting-edge software applications — with a collection of loosely coupled services — which may then be deployed with different logical and physical servers.

What Is SaaS Today?

The SaaS model today is particularly attractive to startups. While companies may utilise a number of business models including B2B, B2C or even B2B2C, a strategic SaaS can benefit them all. Not only do they enable services on a subscription basis, but they provide bundles for a variety of users to help startup founders cover a wider portion of the market.

Pair that with the surging popularity of machine learning, the wide availability of AI features and the ever-decreasing costs of infrastructure and the SaaS concept is a solid bet in an age of uncertainty, as it unlocks a whole host of exciting new business opportunities in Insurance and Finance, Entertainment and Gaming, Productivity, Healthcare and Wellbeing.

Many SaaSes grow with their clients’ businesses. While smaller companies tend to begin with more affordable subscription plans, as they gradually increase their business operations, they are likely to extend their SaaS usage. This in turn leads to a greater amount of data being handled by the SaaS, in addition to an increase in load and utilisation of server resources. In this way, SaaSes will invariably operate in a dynamic environment, so they have to quickly adapt to the evolving needs of their clients and assiduously keep pace with technology.
