WHAT IS MULTI-CLOUD SECURITY

Multi-Cloud Security: Architecture and Ultimate Guide
Adopting multi-cloud is no longer an option - it is an essential element in the fast-paced modern business environment, where agility affects business success. Without strategically addressing the complexity of multi-cloud (AWS, Azure, GCP, OCI), you will not be able to reap the full benefits of this model.
The organization needs a multi-cloud security policy. This article reviews the multi cloud security architecture, requirements, challenges, and best practices.
Cloudy everywhere. Safety is not.
In recent years, the adoption of clouds has accelerated. In the 2021 survey conducted by Flexera, 92% of organizations of all sizes have multi-cloud strategies, and public cloud spending accounts for a larger proportion of the IT budget than in previous years.
Undoubtedly, the organization has accepted all the functions that must be provided in a multi-cloud environment. Although most enterprises have invested heavily in multiple cloud platforms to support Digital transformation and other plans, many enterprises plan to make additional investments to further realize their digital business.
However, for many organizations, the success of being cloudy is still out of reach. For example, according to a survey conducted by HashiCorp in 2021, only 50% of medium-sized companies stated that multi-cloud has helped achieve business goals.
Research has pointed out that cost management, governance, and visibility are common barriers to adoption and deployment. But one factor has always been the most important, which is security - even for advanced users, as their adoption matures, it remains a challenge. In a recent survey by Valtix, 51% of IT leaders agreed or strongly agreed that their company does not want to expand to additional clouds due to multi cloud security architecture complexity.
One driving factor behind these challenges is the expectation that you can easily extend data center or local security frameworks to the cloud. However, to address the security complexity associated with multi-cloud environments, your strategy needs to adopt a cloud-first approach to adapt to dynamic environments.
This article recommends a security model that can help you advance your multi-cloud journey at the speed of the cloud and business.
Proactively addressing cloud security issues
In a perfect world, organizations will systematically and strategically migrate to multi-cloud models. This will enable them to proactively consider safety issues instead of reacting to new risks.
Many companies initially adopted a bottom-up, decentralized - and possibly chaotic - approach. Driven by speed and Functional requirements, they deployed anything meaningful at that time - usually on an isolated island, without consulting other teams or making centralized decisions.
Although these organizations must now work harder to carry out proactive safety work, they have no choice. And the risks are rapidly increasing, which means it is time to take action.
The good news is that many IT professionals already understand that they cannot achieve security in the cloud as they can locally. In Valtix's survey, 89% of respondents stated that they have different views on cloud security in these two environments.
Extending local security to the cloud is not the best approach because:
The legacy security architecture is not flexible enough to adapt to dynamic, service-based, and software-defined public cloud environments.
Security in the cloud requires inherent adaptation to the dynamic characteristics of workloads and applications, and automatic scaling to provide protection.
The different characteristics between various application architectures, cloud network structures, and built-in security tools create inconsistent security states across your multiple clouds, leaving vulnerabilities in your defense.
