In recent years, the cloud revolution has revolutionized IT management models in companies across all sectors. Most of them now use multiple cloud hosting applications and services integrated into the same information architecture.
This so-called “multi-cloud” model has proven itself due to its many operational benefits, but it raises many questions that need to be foreseen in order to reap all the benefits in complete security.
Heterogeneous situations, but common problems
The use of multicloud is carried out in various ways, depending on the data management policy specific to each company. While it is especially common to use separate vendors to meet infrastructure, platform, and application needs, many organizations now run multiple Iaas, PaaS, and SaaS services simultaneously.
A choice that corresponds to the desire to prevent overdependence on the supplier, but which is primarily due to the technical adaptability that it allows. By choosing tailored services for every need and from providers specialized in every task, network administrators can create IT architectures that perfectly match business needs and are always the right size. Financially, it is also a way to take advantage of the fierce competition between cloud service providers to take advantage of the best prices available for each service.
However, these undeniable operational advantages pose many challenges, in particular the significant complexity of cybersecurity efforts. With a significant increase in cyberattacks, linked in particular to geopolitical tensions and the new opportunities provided by the digitalization of companies, the accumulation of cloud services is also synonymous with the multiplication of potential security breaches. Thus, the relationship between cloud services, typical for multi-cloud architectures, can lead to uncontrolled circulation of confidential data and personal data, the processing of which is currently strictly regulated.
Comprehensive overview of security policies
Therefore, for companies aware of these issues, the gradual adoption of a multi-cloud model should be regularly accompanied by a comprehensive review of security and data policies. Due to the constant development of cloud solutions, it is necessary to re-evaluate the compliance of all services with technical, legal and regulatory requirements at regular intervals, taking into account the use and critical nature of the data exchanged.
Particular attention should be paid to protecting the API due to significant differences in the degree of maturity of vendors in this matter. Despite the high complexity that characterizes the data flow pattern in a multi-cloud environment, the goal should be to achieve a unified view of the application ecosystem in order to develop an appropriate security plan. A task in which close cooperation between the company’s partners and its cloud providers is indispensable.
This procedure of constant reassessment of the infrastructure and its security should not be taken as a simple precautionary measure. In addition to cybersecurity, the duplication of sometimes redundant tools and the complexity of IT architectures can sometimes hinder the productivity of IT departments and business teams.
Since this provides a better understanding of a company’s application environment, careful management of multi-cloud tasks can also be a starting point for optimizing security processes as well as business processes.
