Situation: Hybrid Cloud and IaaS Perspectives
Why there is a demand for multi-cloud infrastructure.

How are hybrid clouds doing?
According to the Rightscale poll, already 58% of global companies from different fields use a hybrid cloud. Last year, this figure was 51%. The introduction of such infrastructure is a priority for 45% of the organizations surveyed.
For example, a hybrid cloud uses 21% of retailers from different countries. At the same time, 93% of them consider the hybrid model optimal for fulfilling business tasks. Hybrid cloud is also being introduced by companies from the industrial sphere. Today, 19% of manufacturing enterprises around the world work with him. This figure should grow to 45% in the next two years.
Among companies using hybrid clouds, banks , IT companies, medical and even agricultural organizations are also worth noting.
Why they are chosen
Data security. Companies often see the provider's cloud as a "secondary" training ground, where they upload data backups and operating system images. This allows you to implement the "3-2-1" approach for backup. According to him, two backups are stored on different physical media, and one more - on a geographically remote site.
Also, the hybrid approach makes it possible to organize a Disaster Recovery System (DRS). Not only backups are taken out to the cloud, but also business critical services like ERP or mail server. In the event of a failure on the local infrastructure - say, due to a power outage or equipment breakdown - the reserved services continue to work on the equipment of the cloud provider.
For example, a large restaurant chain in Puerto Rico was able to save and restore data after a massive blackout caused by a severe hurricane. All information was uploaded to the remote site of the IaaS provider.
Infrastructure flexibility. Companies get the opportunity to bring to the cloud only those services that need to be regularly scaled. At the same time, on-premise infrastructure is used only to solve a narrow range of tasks.
An example organization for this case study would be SEGA . The company's testers work in different countries, and they need to regularly send out new builds. During periods of intensive development (for example, before releases), the resources of the local IT infrastructure were not enough to handle a sharp increase in the number of requests. Therefore, the company migrated services to distribute assemblies into a hybrid cloud. This approach accelerated the delivery of necessary files to testers and reduced testing time by 17%.

Compliance with legal requirements. The company uses on-premise capacities to work with data in situations where they cannot be transferred to third-party providers (for example, to comply with GDPR). Other business critical applications (such as mail servers) are deployed in the cloud.
This works the other way - many cloud providers help to comply with legal requirements. For example, we at IT-GRAD offer the Cloud FZ-152 service . The client receives a certified infrastructure that fully meets the requirements of the relevant data protection law. At the same time, the company can use its local IT infrastructure to solve other tasks that are not related to legislation, for example, as a test site.
Prospects
Analysts say the hybrid cloud market will hit $ 97 billion by 2023. At the same time, by 2025, 80% of global organizations will migrate to the cloud - and most of them will deploy a hybrid IT infrastructure.
Large IT companies and cloud providers will help them in this. They are developing new technologies and solutions for working with multi-cloud. Dell and VMware , as well as IBM, along with the newly acquired Red Hat, are moving in this direction. A new system has recently been introduced in Oracle - it is a framework for deploying applications in a public, local or hybrid cloud environment.
The two main drivers are expected to be backup services and DRS. It is also worth noting new approaches to creating IT systems. According to experts, we can expect the popularization of the principle of Infrastructure as Code . In this case, organizations can work with the infrastructure as with code and configure it using software. This approach simplifies the setup of complex and distributed multi-cloud systems.
