Which is Better: Owning a Home or Renting?

Opinions vary but those who are familiar with the subject know: it really depends on your individual situation – there is no single or simple answer to this question.

For who, other than you, can tell whether ownership and full control or flexibility and low risk suits your individual situation the best? There is only one solution: gather good information on which you can base your decision!

Why are we telling you this? Because similar questions arise when choosing between an SaaS or an on-premises solution: Is it better to rent your software against a monthly fee – or to buy it and integrate it in your own IT landscape and host it yourself? The short answer is: each option comes with its own advantages and disadvantages. There is no better or worse. It really all depends on your company’s specific situation.

In this article we have summarized in a clearly understandable form what you need to know about this subject. It will help you to make an informed decision and to communicate it confidently to the management.

SaaS and On-Premises Solutions – What Does That Really Mean?

First of all: what does SaaS or on-premises mean?

On-Premises

In former times the only existing solution – on-premises or on-prem means that software is bought once, then it is implemented in the local IT structure of the company and can be used for an unlimited period of time. The company remains responsible for the administration, maintenance, and hostingof the software.

SaaS

Digitalization makes it possible: software can now also be used in the cloud! When we speak of an SaaS solution we speak of a kind of software rental or subscription – without implementation on local servers. Instead of purchasing a unique license you pay a monthly or annual fee. Hosting, support, and security is taken care of by the provider.

What are the major differences between SaaS and on-premises?

There are advantages and disadvantages in both SaaS and on-premises – which option is best for you depends entirely on your own priorities.

Below you will find some relevant categories in which the advantages of each system are described.

Costs

Without a doubt, the initial purchase costs are a strong argument for SaaS – they are a lot lower than those of an on-premises solution. What is more, you do not need your own IT department or personnel which carries out installation, back-ups, and maintenance – your provider takes care of that!

So, is SaaS the better variant? Not necessarily – especially not for larger companies which already have an IT landscape, it may make more sense to go for the on premisesvariant.

Flexibility

On-premises solutions offer more control and allow you to make major adjustments to the software, so that it can be integrated smoothly with your company processes – including interfaces to other programs.

But SaaS provides a different kind of flexibility: For when your company growsor your requirements change, you can usually extend factors like storage capacityand user licenses – or reduce them if necessary. An additional advantage: employees can more easily access the system from outside thecompany premises.

Installation Effort

When it comes to installation effort, SaaS is certainly the clearwinner. Companies which decide for a subscription can immediately use the software via internet, regardless of their location.

On-premises solutions require some effort for planning and implementationand incur greater costs for the acquisition of the software.

Control

One of the primary arguments for an on-premises solution: Buying a software, integrating it in anexisting IT environment, and adjusting it to meet your individual requirements increases control – this is also due to the fact that all data remain in the hands of the company. For industries with particular data security requirements – e.g. banks and insurance companies – this is of particular importance.

Especially for large companies which already have their own IT environment andwell-trained technical staff, an on-premises solution may be an interesting option.

Data Security

At first glance it seems to be obvious: when it comes to security, on-premises is the go-for variant, right? For any sensitive data remains safe behind your company’s firewall and in SaaS data is saved on external servers!

This is not entirely wrong – which is why companies in strongly regulated sectors with high data security requirements still opt for the on-premises solution. But in SaaS, data security can also comply with very high standards. ISO 27001 certified companies must, e.g., comply with an international standard which governs the treatment of data within a company. You can be sure that all required updates are carried out by professionals on a regular basis.

Another factor: When using on-premises, companies must take care of double data backup and recovery in the case of a server breakdown . In SaaS solutions, the responsibility remains with the provider. In a worst case scenario data recovery is thus a lot easier and does not shatter the nerves of your IT staff!

Data protection and security are arguments in favor of the on-premises variant. However, this is only true if the company has the required infrastructure and know-how.

Adjustments, Support, and Maintenance

If a company already has an IT structure and a competent IT team, on-premises solutions can be a good option.

But with SaaS, companies do not only rent a software but also the corresponding service: maintenance, updates, and support are included. Especially for smaller companies with low personnel resources this is an important factor.

Myth and Reality – Misconceptions About SaaS and On-Premises

Misconception: Storing data in the cloud can never really be safe.

Reality:
This is not true – data protection standards are very high. Especially European providers which store data in line with EU-GDPR, guarantee a high level of security. For companies which process highly sensitive data, an on-premises solution usually presents a good option – also because they can assure their customers that their data remains with the company. But without high internal security standards, constant updates, and a competent IT team, safety is rather imaginary than real!

Misconception: SaaS applications are always accessible via the public Internet.

Reality:
Not necessarily. Companies can provide the services via VPN connection. Via VPN, companies reinforce the security of your SaaS system.

Misconception: SaaS and Cloud are one and the same thing.

Reality:
Even though in everyday language it is often used synonymously, this is not quite accurate: a cloud is a server’s ecosystem in which data can be stored. SaaS, on the other hand, is the software which is made available via cloud.

At One Glance: Advantages of SaaS and On-Premises

SaaS vs On-Premises – Which is Better?

Conclusion: it depends!
So which is better – cloud solution or on-prem? Each company must find its own answer to this question. Now you know the essential differences. By taking into account the specific requirements of your industry, the nature of your internal processes, and the resources of your company, you will be able to decide which option is best for you.
