Hybrid cloud

 

Definition of hybrid cloud

 Hybrid cloud solutions include applications or their components (such as compute, networking, and storage) when deployed across public and private clouds. On-premises servers are often referred to as “private clouds.”

Hybrid Cloud Examples

L'exemple de cloud hybride le plus courant consiste à utiliser un cloud public avec des services de cloud privé et une infrastructure sur site. Cependant, il n'existe pas de configuration cloud hybride unique ni d'architecture unique.

Un cloud hybride peut combiner un cloud public et un cloud privé s'exécutant sur site ou en périphérie. Elle peut également combiner un cloud public avec un autre cloud public (également appelé multicloud).

Les modèles hybrides sont conçus pour permettre à une entreprise de combiner différents environnements et de choisir ce qui fonctionne le mieux pour des applications et des données spécifiques. Par exemple, les solutions hybrides sont populaires auprès des entreprises évoluant dans des secteurs hautement réglementés, qui appliquent des exigences strictes en termes de confidentialité des données concernant la façon dont elles stockent, traitent et interagissent avec leurs données.

Un autre exemple courant consiste à adopter une approche cloud hybride lors de la transition vers un cloud public pour faire évoluer la capacité de manière dynamique lorsque les besoins de calcul ou de traitement dépassent les capacités d'un centre de données. De nombreux projets de migration vers le cloud mènent inévitablement à des déploiements dans le cloud hybride, car la migration des charges de travail et des applications vers le cloud s'effectue lentement et de manière stratégique.

Le cloud hybride est-il identique au multicloud ?

Although these terms are often used interchangeably, they are not actually the same. Hybrid cloud includes different interconnected public and private clouds that work together, sharing data and processes to perform the same task. On the other hand, multicloud approaches use services from multiple public clouds to perform various tasks, regardless of where they are hosted. Organizations that do not want to be dependent on a single cloud service provider can choose to use resources from multiple providers to get the most out of each service.

A hybrid cloud approach can also be considered multicloud if it includes resources from a private cloud and those from at least two public cloud service providers. In other words, multicloud configurations include hybrid cloud configurations, but a hybrid cloud is not automatically considered multicloud.

How does a hybrid cloud work?

Hybrid clouds combine the resources and services of two or more separate computing environments. Hybrid cloud architectures require integration, orchestration, and coordination so you can share, move, and synchronize information quickly.

Good hybrid cloud networking is essential for a hybrid cloud deployment to function properly. Interconnectivity between environments is typically established using a local area network (LAN), wide area network (WAN), virtual private network (VPN), and application programming interfaces (APIs).

Like other cloud computing architectures, hybrid cloud platforms leverage virtualization, containerization, and software-defined networking and storage technologies to abstract and aggregate resources. Dedicated management software allows organizations to allocate resources and enable on-demand provisioning across different environments.

What is the purpose of a hybrid cloud approach?

The hybrid cloud approach is right for you if you want the scalability and security of a public cloud, such as Google Cloud, while keeping your data on-premises to ensure compliance with data residency laws or to keep computing needs closer to your customers. For some of you, hybrid computing is a great option if you work with critical systems running in both public and private clouds.

• Modernize at your own pace. With hybrid cloud, you can migrate applications to the cloud at the pace that works best for your business and transform your technical infrastructure over time.
• Ensure regulatory compliance. In many industries, there are rules governing where your application can be located. Hybrid solutions can help you use both private and public clouds while meeting regulatory requirements.
• Run applications on-premises. Your regulated applications may need to remain on-premises or on mainframe systems that are difficult to migrate to the cloud.
• Run applications at remote edge locations. If you work in industries that require low-latency hybrid edge computing, such as kiosks in retail or networks in telecommunications, a hybrid approach allows you to run a selection of applications at the edge.

Hybrid Cloud Solutions

Today, IT teams are looking to design hybrid cloud environments that use the same technology stacks to keep up with the adoption of cloud native technologies, microservices and container-based architecture, and infrastructure as code.

Over time, hybrid cloud solutions have focused less on interconnectivity between locations and more on workload portability and automated deployment to the environment that best fits the business use case.

Therefore, we recommend thinking about hybrid cloud platforms based on their business, rather than just location and ownership.

A hybrid cloud solution must:

1. consolidate IT resources, services and functionality;
2. automate horizontal scaling and provisioning;
3. freely move workloads between environments;
