Hybrid cloud: the future of flexible and cost-conscious IT?

For years, migrating to the cloud was the mantra for companies with growth ambitions. The reasons were clear:

• In the cloud, you can quickly scale IT resources up and down based on demand.
• Unlike on-premises infrastructure, the public cloud doesn't require large initial hardware investments.
• Public cloud providers often offer automatic backups and replication of data to different regions, which contributes to better disaster recovery and reduced downtime.
• A cloud provider takes care of the management and maintenance of the infrastructure. This frees up the IT team to focus on strategic tasks instead of day-to-day operations.
• A cloud platform is always up-to-date: you always have access to the latest features without having to upgrade yourself.

The Disadvantages of the Public Cloud

While the advantages of the public cloud may be common knowledge, its potential disadvantages are much less well-known. We've listed a few below.

Hidden or Unexpected Costs

While scaling is easy in the cloud, costs often rise unexpectedly, for example, when demand for resources increases rapidly. Long-term data storage costs also often accumulate, especially in sectors like healthcare or telecom, where data retention is legally mandated.

Additional services, such as backups, machine learning, or managed services, can also be expensive. Finally, some cloud providers charge severance fees when you want to migrate data out of the cloud.

Security and Compliance
 

For sectors that require strict data security, such as healthcare, managing data in the cloud can entail risks. Public cloud providers guarantee a secure infrastructure, but many aspects of security and compliance remain the responsibility of the customer.

With a public cloud provider, you often have less control over the localization of your data, which can lead to compliance risks (e.g., GDPR).

Vendor lock-in
 

With a public cloud provider, your organization can become highly dependent on a single provider, making switching providers more difficult and increasing costs. This is because each provider offers unique technologies and services that are difficult to migrate to other platforms, limiting your organization's freedom of choice and flexibility.

Public cloud alternatives 

The public cloud still has its place, of course. But now that we're more aware of its drawbacks, it makes sense to consider alternatives.

On-premises data center

In several sectors where security and data control are paramount, such as healthcare or finance, an on-premises data center is a viable option. On-premises solutions can also be more cost-effective in the long run for companies with fixed, predictable workloads.

On-premises data centers are less attractive for organizations that want to scale quickly, leverage the latest technology, or lack the resources or IT team to manage their own infrastructure.

Hybrid cloud  

As the name suggests, a hybrid cloud isn't just one type of environment, but rather a mix of them. A hybrid cloud combines private and public cloud services with on-premises solutions. Organizations using a hybrid cloud strategy typically store their critical data and applications on-premises or in a private cloud. At the same time, they benefit from the extensive resources and scalability of a public cloud for processing less sensitive data and applications.

A hybrid cloud environment looks different for every organization. The key is to tailor your approach to your organization's specific needs: leverage the flexibility of the public cloud when needed, and leverage the cost advantages of the private cloud for critical services.
