The digital transformation is accelerating the demand for more efficient, flexible and resilient IT infrastructures. To meet these challenges, many companies are adopting hybrid solutions that strategically combine cloud computing, edge computing and the physical data center. 

And the figures reinforce this trend: according to the Flexera 2024 State of the Cloud Report, 89 per cent of companies already use some kind of hybrid cloud model, with 76 per cent planning to increase investments in the public cloud and 66 per cent in the private cloud. 

In addition, Gartner predicts that soon half of the data generated by companies will be processed outside the central data centre or cloud, driving the growth of edge computing.

Faced with this dynamic scenario, combining these three technologies appears to be the ideal solution for balancing performance, cost and control. But when exactly does this integration make sense? Let’s understand how each component contributes to a complete hybrid infrastructure below:

Cloud and Data Center: balancing cost, performance and control

The cloud is renowned for its virtually unlimited scalability and pay-as-you-go model, which adapts to business variations. This flexibility is perfect for variable workloads, temporary projects or unexpected peaks, ensuring that the infrastructure keeps up with demand without wasting resources.

On the other hand, not all applications are suitable for running exclusively in the cloud. Stable and predictable loads, which require continuous processing and constant use, are generally more cost-effective when kept in a physical data center. 

Despite the initial investment, the fixed cost of operation tends to be lower in the long term, as well as offering greater control over legacy systems, critical databases and applications that require specific security, compliance and licensing.

By integrating cloud and data center in a hybrid infrastructure, your company can combine the best of both worlds: optimise investment, maintain strict control over sensitive applications and take advantage of the cloud’s agility for dynamic demands and innovation. 

This union guarantees consistent performance, enhanced security and the flexibility to adapt quickly to market changes.

Edge Computing: fast response close to the data source

As applications that require low latency grow, edge computing is gaining importance. It processes data locally, close to the source, either on devices or servers close to the user, reducing latency and network traffic, and avoiding total dependence on the cloud or remote data centre.

This architecture allows immediate decisions to be made locally, such as controlling machines on a production line, monitoring vital signs in real time or adjusting operations at points of sale. 

Meanwhile, the cloud and centralised data centre are responsible for secure storage, in-depth data analysis and information integration for strategic vision.

Edge computing thus complements hybrid infrastructure by delivering speed, efficiency and scalability, even in locations with limited connectivity or large volumes of data.

Security and compliance: the impact of data localisation

In regulated sectors such as health, finance and government, the rules on data storage and processing are strict. Ensuring compliance with legislation such as LGPD and GDPR requires absolute control over where sensitive data is stored.

In these cases, the physical data centre stands out for offering physical and logical security, facilitating audits and guaranteeing data sovereignty. Keeping critical information “on-premise” may be a legal or compliance requirement.

At the same time, the cloud offers secure, scalable and certified environments for less sensitive data, testing, development and backup. A hybrid architecture makes it possible to combine these environments, guaranteeing security, governance and flexibility, as well as minimising the risk of penalties.

Business continuity: greater resilience with integrated environments

Hybrid infrastructure is also a fundamental pillar for disaster recovery strategies. By replicating data and applications between physical and virtual environments, your company increases resilience against failures, cyber attacks or natural events.

In this model, the cloud acts as an alternative environment that can be activated quickly when needed, without the need to maintain idle resources internally, reducing costs and operational risks.

Gradual modernisation: connecting legacy and innovation

Many organisations face the challenge of modernising legacy systems without interrupting operations. Hybrid architecture makes it possible to migrate applications to the cloud in stages, while maintaining critical services in the data centre.

Meanwhile, new solutions in artificial intelligence, big data or machine learning can be developed directly in the cloud, accelerating innovation in a safe and sustainable way.
