Hybrid Cloud is an infrastructure that combines the public and private clouds to deliver the best of both worlds. Find out everything you need to know about it.
The public cloud has many benefits for businesses. However, it also brings its share of constraints and challenges. In fact, many organizations prefer to stick to the private cloud or an on-site infrastructure.
However, a study published by Nutanix in 2018 reveals that 91% of IT managers of companies consider that the ideal model is that of the hybrid cloud , which combines the benefits of the public cloud with those of the private cloud .
Similarly, by 2019, 451 Research analysts estimate that 69% of businesses will rely on hybrid cloud environments and 60% of workloads will run on some form of cloud service. So, transitory strategy or optimal compromise? Find out what you need to know about the hybrid cloud.
Hybrid cloud: definition
Before defining the hybrid cloud, it is important to understand the distinction between public and private clouds . In the case of a private cloud, the servers are dedicated to a single company. These servers can be on-site, or off-site.
In the case of a public cloud , the servers are shared between the different customers of a provider. The servers are still off-site, since they are located in the provider’s Data Centers.
According to Forrester Research, the hybrid cloud is about connecting one or more public clouds to a private cloud or traditional on-premise data center infrastructure. To put it simply, it is a mix of on-site and off-site IT resources.
More elaborately, the hybrid cloud is a cloud environment consisting of on-premise private cloud resources combined with third-party public cloud resources connected to each other by an orchestration system .
According to the “official” definition of the National Institute of Standards and Technology , the hybrid cloud is “a cloud infrastructure consisting of two or more separate cloud infrastructures that may be private or public and which remain unique entities but are connected by a single technology. standard or proprietary allowing the portability of data and applications “.
Hybrid Cloud: What are the benefits?
One of the key benefits of the Hybrid Cloud is that it can move workloads and data between the public and private clouds in a flexible way based on needs, demand, and costs. As a result, organizations benefit from increased flexibility and additional options for data deployment and usage.
The flexibility is indeed a major advantage of the hybrid cloud . For good reason, in the case of an on-site infrastructure, resource management requires time and money. Adding capacity therefore requires upstream planning. On the contrary, the public cloud is already ready and resources can be added instantly to meet the needs of the business.
Thus, by leveraging the hybrid cloud, a company can leverage public cloud resources when its needs exceed the resources available on private clouds, for example during seasonal peaks. The hybrid cloud therefore provides the elasticity needed to cope with demand variations that can be linked to multiple factors.
In parallel, as in the case of on-premise private cloud storage, the hybrid cloud provides quick access to the most critical data . It is therefore possible to keep frequently used data on site, and to transfer “cold” data to the cloud.
In addition, the hybrid cloud helps reduce business costs with the low cost of IT resources available on the public cloud. Indeed, most public cloud providers offer their customers to pay only for the resources they consume. Unnecessary expenses are avoided.
The hybrid cloud is also ideal for processing Big Data . For example, it is possible for a company to use hybrid cloud storage to store its data and to perform analytic queries on the public cloud where Hadoop (or other) clusters can be scaled to fit the computing tasks. more demanding.
Hybrid cloud: what are the disadvantages?
Despite its many advantages, the hybrid cloud is not suitable for all situations. For example, for small businesses with limited IT budgets , the costs of installing and maintaining private servers may be too high. So it’s best to stick to the public cloud.
In addition, an application that requires minimal latency is not always suitable for the hybrid cloud . It may be better to opt for an on-site infrastructure. However, it all depends on the chosen cloud provider. It is therefore important to consider both the application and the resources offered by different cloud providers to decide whether to opt for the public, private or hybrid cloud.
Hybrid cloud: who are the main suppliers?
Many companies today offer hybrid cloud infrastructures. Among the market leaders, there is of course Amazon Web Services also known as AWS . The US company offers storage, networking, security, application deployment and hybrid cloud management tools.
For its part, Google Cloud has partnered with Cisco to offer an open hybrid cloud architecture . This architecture is based on the Istio open source containerization service, which allows the user to connect and manage connections between on-premises and cloud services.
Another supplier is HPE, which offers a customizable solution based on the needs of the company. Similarly, Dell EMC Hybrid Cloud is a solution that enables organizations working with large workloads to perform their digital transformation for greater efficiency.
Recently bought by IBM for $ 34 billion , Red Hat offers a variety of hybrid cloud products like RedHt Openshift and the Red Hat Cloud suite. Other vendors include Oracle, VMWare, SAP with its HANA platform, and Citrix .
