THANK YOU FOR SUBSCRIBING
Despite the momentum, pockets of hesitation prevail, multi-cloud architectures are quickly becoming the preferred strategy at most of the enterprises.
FREMONT, CA: According to the IBM Institute for Business Value (IBV), more than 85 percent of companies are already operating in muticloud environments, and it is predicted by 2021, 98 percent plan to use multiple hybrid clouds. After adopting cloud, application modernization trend follows, with a massive part of it being microservices architecture breaking down monoliths into single-job oriented, containerized services exchanging data over APIs. Multicloud offers agility and cost efficiency with its flexibility to differentiate workloads in numerous environments based on their specific requirements; therefore, most of the companies are utilizing more than one cloud for their application.
The aspects that the IT and security team has to be aware of when it comes to security aspects of containerized applications are:
Integrated Cloud Security and Management
It is essential to monitor the multicloud ecosystem or invest in multicloud management tools which can enable in setting up policy-based compliance profiles. Visibility can be brought to multicloud assets as well as apply cloud configuration policies to secure those consistent settings are used throughout the ecosystem with the help of modern multicloud management.
Vulnerabilities of the Applications
The modern applications are robust in general as they provide a solid baseline to construct on top of, although they need vetting applications against publicly known common vulnerabilities and exposures (CVEs) raised against those libraries. Some public clouds also provide integrated vulnerability scanning services which can identify issues in the container image and obstruct them from being deployed as well as detect containers configuration drift during their lifetime.
Applications largely depend on external authentication providers, and there are some disparities in identity and access management (IAM) solutions available in public clouds. Despite an ongoing effort to ensure that they are standardized, organizations should be sure of utilizing the commonly adopted authentication patterns to avoid cases where some parts of the app are secured in a better way compared to others which are running on different clouds.
To conclude the organizations that are moving to multiple hybrid clouds can augment their cloud security posture with the help of a centralized method for tracking all the critical aspects of multicloud ecosystems, coupled with various data feeds and cross-correlating them obstructing the known security issues to safeguard the business.
