The multi-cloud strategy translates into the use of multiple cloud services of the same type (private or public) within a company. The use of multiple cloud providers allows the company to diversify its functionality and services offered to customers. Here is everything you need to know about multi-cloud, its pros and cons.
What is multi-cloud?
A multi-cloud is a concept that uses multiple cloud services from a variety of providers. These cloud services are either private or public.
Multi-cloud is a major asset for businesses. It gives you the opportunity to benefit from multiple hosts for your multiple applications. So, if a feature is not available on the cloud you've subscribed to, you can sign up for another cloud offering in parallel.
Different types of cloud
There are several cloud deployment models, and the top three are:
- Private cloud: This infrastructure is intended to be used exclusively by a company with many customers. The cloud will be administered, managed and operated by the company, or its subcontractors;
- The public cloud: This model is intended for consumer use. The infrastructure using this model may be a company, a micro-enterprise, a public administration agency or even a university. They will be able to operate, administer and manage the cloud from the provider's site;
- Hybrid cloud: In this model, several cloud infrastructures (private and/or public) are linked by standardized technology that allows the organization using a hybrid cloud to manage its multiple cloud services on the same portal, allowing for simpler management of data transferred across all cloud usages.
Difference between multi-cloud and hybrid cloud
Even if the goal of multi-cloud and hybrid cloud remains the same: to be able to use multiple cloud systems for a company, the way they work is fundamentally distinct.
In the multi-cloud, several clouds of the same type (private OR public) are deployed but their management, administration and operation remain carried out separately.
On the other hand, with hybrid cloud, the cloud used can be private and public and their deployment is linked by integration or orchestration functions.
The use of these two cloud approaches remains exclusive and it is of course not possible to use a multi-cloud and a hybrid cloud within the same organization.
Nevertheless, more and more companies are opting for cloud hybrid, which combines both public and private cloud, improving the security of data transfer, which is much more simplified in management.
Pros and cons of multi-cloud
A multi-cloud strategy can be interesting in many ways. Generally less expensive to purchase than an hybrid cloud strategy, the multi-cloud approach allows businesses to gain opportunities. However, the multi-cloud offering also has significant drawbacks. Here are important things to know before choosing this strategy within your company.
The benefits of a multi-cloud
- Supplier Diversity: The multi-cloud principle allows businesses not to be blocked with a single type of cloud. This will allow you to choose different suppliers based on your specific needs and the prices offered for each option;
- High availability: Using a multi-cloud adds extra security compared to a single cloud. Whether it's data protection or the fight against it outages and threats, multi-cloud provides additional help. When a cloud breaks down or is not available, the use of other clouds continues, ensuring continuity of services provided to users;
- Flexibility: Using multi-cloud allows you to make a choice that suits you according to your business needs, budget, and other specific requirements. You will no longer be dependent on a single provider and will be able to diversify your hosts to ensure better profitability in the exploitation of data and applications;
- Proximity: Data processing times can be long for users located a very long distance from your business and the cloud management center. Using a multi-cloud allows you to use a cloud host closer to your customers. This solution will allow users to have all the necessary services with reduced response times. However, it is important to take into account, depending on the country of hosting your cloud systems, the laws that govern the use of data, so you will have to adapt and follow the rules of the countries in question.
The downsides of multi-cloud
- High costs: By encouraging the purchase of multiple cloud services within your cloud strategy, you will increase the budget needed to use your cloud accordingly. In addition, some cloud providers offer advantageous offers based on large quantities purchased. With a muti-cloud strategy, you won't be able to take advantage of these offers, because usually you buy smaller quantities from several different vendors. For example, the use of a multi-cloud strategy can have a significant impact on a company's purchasing power;
- Complex management: Generally, a cloud platform is very difficult to understand and you will need many human and financial resources to manage, administer and operate it properly. Not all cloud platforms work the same way. As a result, in a multi-cloud strategy, you'll need a lot more time, human and financial resources to manage the multiple platforms available;
- Security issues: Data security is becoming a key issue for businesses. Whether it's to protect confidential company data, or to protect customer information, data protection is the best way to protect the company and prevent sensitive information from landing in the hands of malicious people. The use of several different clouds could initially enhance the security of the data transmitted. However, the more complex the multi-cloud approach, the more apparent the potential security vulnerabilities will be. It will therefore be essential to strengthen security as much as possible. In addition, poor management of the multi-cloud environment or lack of frequent updates could weaken the security system;
- Public cloud OR private: This is one of the biggest drawbacks of multi-cloud strategy. You can't mix between private and public cloud. To date, more and more companies are opting for strategies using private and public cloud. Mixing different types of cloud allows a company to significantly enhance the security and protection of its data.
A multi-cloud strategy gives users greater flexibility regarding cloud providers, but also services which can be close to users, and high availability. However, management remains very complex as each cloud provider offers its own management and administration platform. So, it's important, before whoosing your strategy, to define your business needs and learn about the hybrid cloud that could be more beneficial in many ways.
