Multi Cloud Management: Pros and Cons

Multi-cloud enables parallel use of multi-vendor cloud services and platforms. From the user’s perspective, it behaves as a single large cloud. The multiple cloud can integrate several cloud models such as the private or public cloud. In this article we will see the multi cloud management, pros and cons.

Multi Cloud

Connecting several cloud services to a common cloud: a multiple cloud describes the parallel use of different cloud providers. The Multi-Cloud can be considered as an evolutionary step in Cloud Computing and represents a kind of extension of the Hybrid Cloud model.

In a multi-cloud, cloud services and cloud platforms from different providers are combined into one large cloud from the user’s point of view. Like the Hybrid Cloud, the Multiple Cloud can integrate several cloud models such as the Private Cloud or the Public Cloud. Possible services in the Multiple Cloud are the usual cloud computing services such as IaaS (infrastructure as a service), PaaS (platform as a service) and SaaS (software as a service). The aim of multi-cloud is to use the services, applications and infrastructure of the cloud structures of several providers in parallel and therefore act independently of a single provider. Services can be purchased from the most appropriate provider based on requirements, desired performance and price.

Thanks to the Multi-Cloud, companies have a wide range of options for making the best choice. Various public cloud solutions can be used, such as those from Amazon, Microsoft and Google or other providers. The Multi Cloud is managed through a central management console, which groups the administration of all services. This allows the company itself to implement the optimal variant for its needs quickly and flexibly.

The Multiple Cloud in contrast to the Hybrid Cloud

Although the multiple cloud and the hybrid cloud are based on the same cloud models, the concepts can still be clearly distinguished. The Hybrid Cloud extends the resources provided exclusively in a private cloud with the Public Cloud. If required, the Hybrid Cloud can flexibly scale computing power, storage space or other services from the Private Cloud with services from the Public Cloud.

The advantages of a hybrid cloud compared to a purely private or public cloud

  • Fast and flexible reaction to changing needs
  • Comply with security, privacy and compliance requirements easier
  • Management and unification of the IT environment
  • Further use of existing technologies
  • Good scalability of services
  • Optimizing business processes and accelerating innovations

Compared to the Hybrid Cloud, the Multiple Cloud offers an even greater scope in terms of cloud models and their combination. You can use cloud services from different providers in parallel. For example, IaaS, PaaS or SaaS can be obtained from different service providers. Different deployment models are also possible, such as hybrid cloud with private and public clouds. Thanks to a uniform management interface, users still have a common platform. The Hybrid Cloud is a kind of transition from the Private Cloud and Public Cloud to the Multi-Cloud.

In the Multi Cloud, comparison with the automotive industry and its various providers is often used. In the Multi-Cloud, the different automotive industry providers represent the different providers in the Cloud. In some cases, the same services (vehicle components) can even be purchased in parallel from different providers. The Multiple Cloud combines the individual services of different providers into one large cloud, in the same way that the car manufacturer combines the various components of the individual providers into a single vehicle.

The advantages of the Multi-Cloud

Compared to other cloud models, such as the hybrid cloud, public or private, the multiple cloud has numerous advantages to offer. The multiple cloud is a solution to the problem that there is no single cloud service that optimally adapts to all deployment scenarios. Cloud services that ideally meet the requirements for a particular application or service may be completely unsuitable for other services.

In a multiple cloud, it is possible to flexibly select the cloud provider and cloud service that best suits the application or service in question. At the same time, the use of different cloud providers protects the enterprise from dependencies. Risks from these dependencies can be minimized by using different providers in parallel. If there are changes in the cost structures and performance of the providers, the multiple cloud enables the company to react flexibly and achieve optimum results.

Another advantage of using service providers in parallel is increased availability and reliability. By using different cloud platforms, the risk of a single provider failure affecting the entire company is reduced. Ideally, failed services can be obtained flexibly from an alternative provider to cover a failure. If a single cloud provider disappears from the market, this is not usually critical either, as the required cloud services can easily be obtained from a new provider or from a provider already in the multiple cloud.

Applications that have high demands on computing power, storage requirements or network performance can be run with a provider that meets these requirements. Other non-critical services can be hosted by a low-cost provider. The resulting service mix has a positive impact on both IT costs and application performance.

The Disadvantages of Multiple Cloud

The concept of the Multi-Cloud also has some disadvantages. These disadvantages can be summarized as follows:

  • The greater the number of providers and cloud models used, the more complex and difficult it can be to manage the entire solution
  • The number of possible interfaces and sources of error increases
  • A greater effort for the administration and invoicing of services due to the large number of different providers
  • There is no uniform concept of data protection and security due to the many different individual concepts of the providers and the resulting inconsistencies.
  • It is difficult to reconcile the company’s compliance guidelines with the various data protection concepts of suppliers.

Multi-cloud management

To efficiently deploy a multi-cloud solution in the enterprise, it is necessary to have a holistic view and control of cloud services and IT infrastructure. Cloud management platforms (CMP), which bring together the various cloud providers under a common management interface, are used to meet this requirement. All cloud models, such as private cloud, public cloud, hybrid cloud and multi-cloud, can be mapped onto these management platforms. Both the company’s own data centre resources and the virtualised services of the different cloud providers can be included. Ideally, the cloud management platform should capture and visualize the entire IT landscape and enable central management of all services and resources.

Multi Cloud FAQS

What is multi cloud in cloud computing?

Multi-cloud (also multicloud or multi cloud) is the use of multiple cloud computing and storage services in a single network architecture. This refers to the distribution of cloud assets, software, applications, and more across several cloud environments.

https://avinetworks.com/glossary/multi-cloud/

What is a multi cloud approach?

Multicloud is a cloud approach made up of more than 1 cloud service, from more than 1 cloud vendor—public or private. For example, your enterprise invests in expanding a cloud infrastructure… But eventually, customers start asking for features that are only available through a different vendor’s proprietary app.

Why use multi cloud strategy?

There are several commonly cited advantages to multi-cloud computing, such as the ability to avoid vendor lock-in, the ability to find the optimal cloud service for a particular business or technical need, increased redundancy, and the other beneficial uses mentioned above.
