In the IT world, two types of philosophy clash when choosing a software solution: SaaS or OnPremise?
SaaS: For Software as a Service, i.e. a software solution available online and marketed as a service, i.e. in the form of a subscription. It is also often referred to as "Software in the Cloud".
OnPremise : The software solution is usually sold in the form of a licence plus a possible annual maintenance at the publisher. The solution is then installed at the customer's premises.
OnPremise: An architecture in the company and at the company's expense
As part of an OnPremise software solution, the entire solution is installed at the customer's site.
The customer therefore has control over the entire tool: access to machines, database, application files, ...
The data is therefore located at his home and not at the software publisher or a host chosen by the publisher. This point can, in some contexts, make the difference.
Depending on the solutions and the editor, the customer also has the possibility to customize his software to fit his specific needs. This is particularly the case for ticketing or ITSM solutions.
By having control of his infrastructure, the customer must however maintain it himself in operational conditions: ensure backups, software and OS upgrades, ensure the supervision of his infrastructure, bear the cost of hardware and its renewal, ....
Deployment is often longer and more time-consuming because it requires the implementation of dedicated infrastructures.
SaaS: An outsourced architecture for a fixed cost
As part of a SaaS solution, the entire solution is hosted and maintained by the software publisher. The database can then be specific to each customer (we speak of a unique tenant per customer) or common for all customers.
Version upgrades and maintenance are then fixed by the solution provider, often within the least restrictive schedules, but not chosen by the customer.
The recurring cost of the solution is fixed, known and controlled often depending on the number of users, access, resources used ....
Set-up is often very quick and is limited to account creation and the deployment of a few necessary prerequisites.
What about supervision solutions?
The world of supervision, like other software, offers SaaS and onPremise solutions, and editors like Coservit even offer both solutions to meet customer demands.
In the case of ServiceNav, the maintenance of the OnPremise solution is a real question to ask before making your choice. The SaaS mode of the solution provides a turnkey solution that is easy to deploy, secure and with controlled costs. Regular version upgrades (between 10 and 12 per year) are supported by Coservit outside the 8am-8pm (weekday) time slot, allowing high availability of the application.
The time saved in maintaining the solution can then be spent on higher value-added tasks.
The guarantee of data storage in the datacenter of a French hosting provider, allows to answer to the problems of data confidentiality.
Whether SaaS or OnPremise, each solution has advantages and disadvantages.
However, the SaaS mode, thanks to its lighter constraints for the customer and a final cost close to or even lower than the OnPremise solution, is becoming the standard for more and more market players.
