Open Software as a Service

Open Source Software Solutions will dictate how cloud-based on-demand services are going to be delivered avoiding Lock-In for Open Businesses in the cloud era.

Our Open SaaS Definition

Simply put, Open SaaS means Open Source Software provided as a Service in the private or public Cloud which combines the power of distributed open source model with the multitenant model of Application Service Providing (ASP), known as Software as a Service (SaaS). The term SaaS is a clone of ASP and SOA (Service Oriented Architecture) in the cloud era.

SaaS

Classic SaaS offerings like Google Apps, Salesforce, Microsoft Office 365 are closed source platforms with multi-tenancy support, users share the same code, databases and servers for better utilization of software and hardware. The drawbacks and disadvantages of SaaS is Vendor-Lock-In, the lack to customise the software for unique needs and has often long release cycles.

Open Source

Open Source Software is adaptable and has a rapid evolutionary process with No-Lock-In, short release cycles to leverage the innovation and agility of businesses. On the other hand Open Source Software is deployed for each client on separate server instances and does not leverage the scale efficiencies and multi-tenancy as by classic closed source SaaS offerings.

Open SaaS

Open SaaS combines the benefits of the both worlds and combines Open Source Software and SaaS with the scale efficiencies of the Cloud and is fully customizable for each customer on a unique instance and can provide higher security in the private and even public cloud. In most cases running unique instances on the cloud is more efficient than running multiple customers on a single instance on the cloud or in a co-location facility.

Open SaaS on Open PaaS and Open IaaS

Since Open SaaS supports the multitenancy model and the openness of open source software, it can run on Open PaaS which in turn can run on top of Open IaaS or even on non- virtualized environments!
