Businesses all, or will all, resort to public cloud services in the short or medium term . The Cloud is the ideal model for troubleshooting internal technical support, IT agility, and cost.
Many cloud providers specialize in all business and financial functions, which could be a compelling argument for the cloud. In fact, this is the problem that many users encounter. Given the diversity of their own needs and the growing specialization of cloud providers, many companies can choose multiple service providers and use multiple clouds.
A multicloud strategy allows you to adapt each cloud offer to each need. But this configuration does not go without a new dose of complexity. In a multicloud model, it's easy to lose control. With a few precautions of rigor, a multicloud strategy ends up offering a large number of advantages.
What is Multicloud?
If you have the ability to run multiple clouds, you'll have a hard time understanding why businesses think a single cloud will help them better address their IT challenges.
After all, each of these three service models - IaaS , PaaS and SaaS - responds to a specific scenario. In IaaS mode, it is about hosting virtual machines, which avoids heavy investments and any geographical constraint , but leaves users responsible for managing software licenses, technical support costs and business agility. PaaS mode offers software licensing benefits and reduces platform software support costs, while SaaS mode converts an application into service, effectively eliminating virtually all traditional costs.
Because companies rely on personal productivity tools, such as office suites and collaborative software, hosting the core server components of these tools in PaaS mode can avoid all the problems associated with updating software. . It also reduces the need for support and gives users access to better applications.
But it's another cloud support needed for the company's core applications.
The ideal would be to have resilient applications, able to operate even in the event of local power failure and others that can expand or reduce their wings depending on the workload. To do this, you will need to be able to expand the capacity in a public cloud, and it is IaaS that ensures the most control, security and governance. It's sort of an "elastic" datacenter to infinity.
Some departments of the company have other needs.
Employees may require CRM, analytical tools or data modeling, or other features that are accessible from anywhere and maintained to meet regulatory requirements. In this context, SaaS has become the preferred solution of trades. This model is all the more interesting when the inertia of internal IT processes is such that it no longer allows the company to compete.
When to adopt a multicloud strategy?
What is the best cloud model for your business? No solution can be better than another. And resolving to use only one cloud model inevitably ends up creating trade-offs and minimizing profits. So why not deal with multiple clouds?
If you believe in the cloud and its future evolution, if your business is under competitive or regulatory pressure, or if it is likely to be involved in a merger or acquisition, the adoption of multiple clouds is appropriate.
Other factors could also come into play to make your business an ideal candidate for a multicloud strategy . For example, there is a strong reliance on multiple hosting platforms in the datacenter or on widely distributed servers.
Another factor comes into play. If business entities are poorly organized, which is often the case when one company buys another, it's a safe bet that each company will have its own IT strategies and drivers and will have already chosen its "ideal" cloud provider. ".
In the longer term, however, a company will have to unify IT applications and services. In other words, the choice of different clouds should also be homogenized.
