Three advantages why you should adopt this model in your IT

The Hybrid Cloud IT model provides for IT resources to be built through different clouds between private clouds (and/or IT on premise) and one or more public clouds. This type of infrastructure is the most widely adopted in the IT world today and has, in fact, some undeniable advantages that IT managers have found over time and that companies particularly appreciate; let us therefore clarify.

What are the differences between public, private and multicloud?

A private cloud is a cloud computing model dedicated exclusively to a single organisation, with well-defined users. It may be hosted in an organisation’s data centre, in a third-party co-location facility or mediated by a private cloud provider that offers private cloud hosting services and may or may not also offer a traditional shared multi-tenant public cloud infrastructure.
The public cloud is an IT model in which infrastructure and on-demand computing services are managed by a third-party provider and shared with multiple organisations using the public Internet. Public cloud service providers can offer users cloud-based services such as Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) or Software-as-a-Service (SaaS)
The public cloud allows anyone to purchase computing resources. Typically, multiple users share the use of a public cloud. In contrast, the private cloud includes cloud-based services that are hosted within an organisation’s private servers.
Multi-cloud is a cloud computing model in which an organisation uses a combination of clouds, which may be two or more public clouds, two or more private clouds or a combination of public and private clouds.
Both ‘multi-cloud’ and ‘hybrid cloud’ refer to cloud implementations that integrate more than one cloud. They differ in the types of cloud infrastructure they include. A hybrid cloud infrastructure combines two or more different types of clouds, while a multi-cloud combines several clouds of the same type.

Hybrid Cloud: three main advantages why you should adopt this model in your IT

A multi-cloud is a superset of multiple public clouds, hybrid clouds, on-premises and edge environments. A multi-cloud deployment model is based on the use of more than one public cloud service provider for computing or storage resources, independent of the use of another private cloud or on-premise infrastructure. A multi-cloud deployment that includes a private cloud or on-premise infrastructure is considered a hybrid multi-cloud.
A multi-cloud strategy not only offers greater flexibility for the cloud services a company chooses to use, but also reduces dependency on a single cloud hosting provider.
There are several reasons to adopt a multi-cloud platform. Let’s look at some examples.

Provider-specific services: organisations can choose between different cloud providers to better align application and infrastructure requirements with their business needs.

Improved scalability: when demand increases, an organisation can quickly scale to multiple cloud providers.

Containers and microservices: Organisations using microservices when developing containerised applications with Kubernetes may find that some services are only offered by a specific cloud provider. As new services come to market, multi-cloud Kubernetes deployments are becoming increasingly popular, hosted by a variety of cloud providers.

Reduced latency: distributed organisations can reduce latency by choosing local public cloud vendors based on the location of each facility. This also simplifies multi-cloud networking, as all major cloud providers are connected to each other with fast, low-latency connectivity.

Regulatory and governance obligations: some organisations may need to utilise multiple cloud storage providers to comply with applicable regulations and data sovereignty laws that require certain types of data to reside in specific geographic locations.

Reduced Footprint and Cost: Most organisations using multi-cloud capabilities use the public cloud for infrastructure, avoiding the need to create and manage their own data centre and creating a virtual data centre in the cloud without the need for physical hardware components. In this way, the company saves money and physical space as it does not have to invest in hardware and does not have to physically own it. The company also saves time as the public cloud service provider manages the data centre and maintains and updates it.

Bargaining power: opting for multiple cloud services offers advantages that far outweigh the risk of any problems associated with using different vendors. By adopting a multi-cloud strategy, companies can choose the provider that offers the best price for a given service, thus helping to ensure that all providers continue to set competitive prices for their products.

As mentioned, the Hybrid Cloud is a way to utilise IT resources by taking advantage of services that can be hosted and offered by on-premise IT, ‘private cloud’ solutions and one or more ‘public clouds’. Here are the three main advantages of adopting the hybrid cloud model:

Sharing between infrastructures: the hybrid cloud is essentially a combination of on-premises and off-premises infrastructures. One of the advantages of the hybrid cloud model lies in its capacity for dynamic scaling. It is a particularly elastic model whereby IT can easily and quickly acquire resources when needed and then release them when no longer required, thereby optimising the resources themselves and the associated costs.

Cost-effectiveness: The aspect of sharing between infrastructures translates directly into a more cost-effective solution, as organisations do not need to acquire oversized infrastructures to meet any temporary needs, but can allocate the correct resources to each application, optimally balancing peak-related fluctuations and security requirements. Another typical use of a Hybrid Cloud model is whereby even smaller organisations can build Disaster Recovery infrastructures by taking advantage of public cloud and/or multi-cloud characteristics.

Flexibility: The hybrid cloud provides the flexibility to rapidly deploy apps and environments, bring new projects to life, create test and development areas by enabling the possibility of moving workloads between on-premise data centres and public cloud environments. The adoption of different public cloud service providers also enables cost optimisation for a similar service (usually at the price of increased management and control complexity).
