In the previous article, let us know how to As the challenges of an organization become increasingly complex, a single cloud computing solution is not enough to answer to the needs of the organization. But What if the needs are so great that a single provider does not have enough infrastructure to provide a comprehensive response. It is for those cases that the term multicloud was developed to define un cloud approach comprised of more than one cloud service, provided by at least two providers public or private.
Before continuing to describe the multicloud approach, I will link you to the other articles in the series.

Combining types of clouds. When to use the multicloud approach
Although multi-cloud solutions is the most recent addition to the offering available, it has seen rapid acceptance. According a survey commissioned by IBM 85% of the companies consulted use them.
The advantages of opting for this type of approach are:
- It can be obtained a cost more low opting for those services in which each provider has a lower price.
- Possible achieve better service combining those features in which each provider is better.
- Makes possible avoid dependency from a single provider.
- Lets offer better response to contingencies hiring the same service from two different providers.
Those organizations that opt for multi-cloud solutions can determine which workload is best suited for each cloud based on your specific needs. In this way, different mission-critical workloads within a single company will meet their own requirements for performance, data location, scalability, and compliance, and certain vendors' clouds will meet these requirements better than others. For example, a multinational in the oil industry will need different computer resources to manage the following:
- An inventory app for sourcing and assigning materials for drilling and extraction
- A geographic information system to keep up-to-date information on the different farms throughout the world.
- Accounting management programs capable of working with different currencies
- A CAD solution for creating more efficient management tools.
Difference between hybrid cloud and multi-cloud solution
As I said in the article in which I discussed the different types of cloud. The border between them is quite blurred and a debatable question.
Multiple clouds and hybrid clouds they are different but often complementary models. Hybrid cloud uses a mix of public and private clouds to meet the needs of IT solutions. The goal of the hybrid cloud is to make everything work together, with varying degrees of communication and data exchange to better manage the daily operations of a company.
In the multicloud approach, it is chosen the contracting of two or more suppliers of cloud service solutions.
In summary, the main advantage of the multi-cloud approach is that the flexibility to quickly adopt the best technologies for any task. The main drawback is the complexity involved in managing many different technologies from many different vendors.
Another point to take into account is the advantages in terms of security.
The multicloud cloud approach toIt helps mitigate risk in two ways: limiting exposure to a single vendor and preventing vendor performance issues. In a multicloud environment, if a particular provider's cloud experiences downtime, the outage will affect only the service it provides to its customers. For example, if your web email product is down for a few hours, services contracted with other companies, such as website hosting or software development platform, will continue to be operational.
