On-premises or public cloud: how do you choose?

Almost every organisation in the world is aware of the benefits that the public cloud has to offer, but most of them still prefer an on-premises environment for their workload. They weigh the advantages of a public cloud solution against the risks and decide that security and control are too important to give up. However, the question should not be what to choose, but how to ensure that you can enjoy the best of both worlds.

The public cloud has convinced enterprise leaders in all industries. According to a survey by 451 Research, commissioned by Hewlett Packard Enterprise, a staggering 97% of more than one thousand questioned IT decision-makers think the public cloud is a positive experience. Despite this clear belief in public cloud solutions, many enterprises keep their workload located on an on-premises infrastructure.

Even when they decide to shift to a public cloud, they often return their data to a private environment after encountering the many pitfalls of this new world. Not every organisation is the same, so choosing the right cloud environment can be different for every company. That’s why we must look at the main benefits and disadvantages of private and public clouds. Which path is the right one for your organisation?


Public cloud

We start with the public cloud. Why are so many enterprises convinced that shifting to the public cloud would offer them amazing benefits that could transform their business?

  • Organisations need to keep their IT budget under control. Especially after the COVID-19 crisis, cost-efficiency will be an important factor in all business decisions. But IT is also more than ever the backbone of any organisation. A public cloud solution enables companies to simplify their IT and pay for what they use. In a private environment, businesses often invest in more capacity than what they need, just to be on the safe side.
  • To keep up with changes, organisations should be able to respond quickly to trends and developments. In an on-premises infrastructure, IT often slows down the business. It can take months to deploy a new solution and this is an eternity for a modern company. In a public cloud, resources are hosted on the premises of the service provider. Enterprises can access new resources whenever they want.

Public cloud environments are saving organisations time and money, both essential ingredients to flourish in this rapidly changing world. On the downside, you can only enjoy the full potential of the public cloud if your company is willing to give up control over security and compliance. It is no surprise that those are the most important characteristics of an on-premises infrastructure.

Private cloud

The lack of control in a public cloud environment already makes it clear why companies continue to work with a purely private infrastructure, although this is by far the most expensive option.

Some organisations have no choice but to run their applications locally:

  • In a private environment, organisations are in control of all data. They decide where this information is kept, who has access and how it is used. Privacy concerns and strict regulations are important reasons why companies hesitate to shift data to a public cloud. Especially if your enterprise is operating in a highly regulated industry, you need an extreme level of control over your assets.
  • Sensitive information should always be handled with care. This is no guarantee when data is stored in a public cloud environment. Your organisation would depend on the cloud provider to ensure the security of the data. In some sectors, such as the banking industry, the sensitivity of data is simply too important to risk security issues. Ultimately, the loss of data can be much more expensive than missing out on the financial benefits of a public cloud solution.

Security, compliance and privacy are the main reasons why companies want to retain control of their data. It is of course frustrating that they have to miss out on the profit and flexibility that a public cloud computing model would offer them. So what if we tell you that there is a way to enjoy these benefits without giving up control?

Hybrid cloud

Many organisations already use a multi-cloud approach. This means that they are running more than one private and/or public cloud solution. An even better strategy is migrating to a hybrid world. This would allow you to shift applications to a third-party public cloud environment and keep specific data or tools within a secure on-premises infrastructure.

A hybrid cloud solution provides companies with the control they need to ensure security, privacy and compliance, and it still gives them access to the financial benefits and the flexibility of the public cloud. Especially if your company is using a lot of sensitive data, a hybrid cloud can open a new world of opportunities. It ensures faster, simpler and more cost-efficient IT while your IT department is still pulling all the strings. A consumption-based model that focuses on your needs allows you to pay only for what you use.

To discover how your company can benefit from a hybrid cloud solution, you can rely on the expertise of a trusted IT partner. Computacenter introduces its customers to HPE GreenLake as an effective consumption-based model. Do you want to know how you can also benefit from this solution?
