According to the "RightScale State of the Cloud" report, virtually every company (84%) that uses infrastructure-as-a-service (IaaS) or platform-as-a-service (PaaS) clouds uses more than one provider. Most employ three or more public clouds from leading providers such as Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP).
There are a number of trends driving this multicloud proliferation, including the need for greater agility, flexibility and scalability, better network performance, improved risk management, avoiding vendor lock-in, and getting more-competitive pricing.
Each of these cloud platforms uses a different, built-in identity system that creates separate silos. Meanwhile, identity-as-a-service (IdaaS) solutions that manage access to SaaS apps introduce yet another separate identity store. Despite this accelerating cloud adoption, many organizations still run the majority of their critical business applications on-premises using a hybrid model, creating even more identity silos.
As a result, the coexistence of multicloud and hybrid clouds introduce an inherently distributed architecture that spans multiple platforms and identity systems. This "new normal" is transformational, not incrementally different from what came before.
Adopting a Distributed Security ModelThe challenges associated with implementing security that can span multicloud and hybrid-cloud architectures is being complicated by the fact that identity has become the new security perimeter because many users are accessing apps and data from outside of the firewall.
Initially, many organizations try to set up multicloud infrastructures manually but quickly discover that identity management efforts don't scale due to a lack of staff and expertise, which results in misconfiguration errors, slow process times, and increased costs. In addition, most organizations have significant investments in l ..
