What is the complexity of managing hybrid cloud| 08.10.2020
The combination of public and private cloud, also known as the hybrid cloud, today looks to be the most natural way of development of it infrastructure for medium and large organizations. In theory
this model allows to combine the advantages of both approaches – flexibility and scalability of public services, and reliability and manageability their own data centers. Thus, each
the application can be placed in the most appropriate environment for her. Not surprisingly, according to research ECI 2019 85% of companies believe the hybrid cloud is the perfect model of it.
But how about the reverse side of the coin? To better understand the key issues that arise in the operation of hybrid clouds, the company Vanson Bourne to-order Nutanix interviewed 650
the decision makers in it, from different companies worldwide.
The study revealed that 96% of companies (i.e. almost all) have encountered difficulties in managing applications and data by placing them in private and public clouds. 69% said
the transition to this model takes more time than they expected.
Part of the problem adds a public component to the hybrid cloud. It turned out that in the matter of transfer of loads on public cloud platform is much easier said than done. 71%
respondents noted the difficulty of migration, and 75% indicated the need for adaptation or re-engineering applications as the main obstacles of transition to the public cloud. And for some
application for such a transfer was impossible.
The main problem of managing multiple environments – private and public – concerns for data security, as said 54% of respondents. Next on the priority issue of personnel, it
only 1% yielded the palm to safety. Staff shortages are understandable when we remember that to work with on-premises infrastructure and cloud services need different tools and knowledge.
Thus, 88% said lack of qualified it staff to manage the hybrid cloud. It is noteworthy that half of the companies realized the problem only when already started
migration.
Because companies have to rely on separate teams for the operation of public and private cloud, this along with the complexity of migrating applications and data increases the isolation
used cloud environments from each other. Such fragmentation increases costs: 49% of respondents noted an increase in required resources, 45% of the increase in costs and 43% said ineffective
the use of resources. And 34% said reported slower decision-making. In the current environment, when many are focused on resource optimization and speed changes, the data can
to exacerbate concerns about investment in this model.
Another set of problems associated with the licensing policy products, which in its current form is not very suitable for hybrid cloud. 58% of organizations faced with the complexities of licensing, and
as many have noted the problem of dependence on the supplier.
However, the respondents, despite all the difficulties of the current implementation, demonstrate remarkable solidarity in the prospects for the development of hybrid clouds. 95% believe their organizations will
profitable solution that provides consistent operation in public and private clouds. This requires the right management tools – so say 96%, and 88% believe that they
will help standardize and simplify operations in the cloud.
Speaking about Russia, we can mark a lower level of penetration of cloud services – as their public data centers and private – compared with countries that participated in the survey.
This rapid development of the domestic cloud providers and their services confirms that we are in a position to quickly catch-up. Nevertheless, it is important to anticipate difficulties and take into account the experience of companies
those that passed this way.
The results show that a unified hybrid cloud environment, ensuring a uniform experience, tools and methods of work in several private and public
the clouds will help to remove the problem of isolation and to improve operational efficiency and to some extent will help to overcome difficulties.
