This diverse model can often offer the best
of all worlds by accommodating different
business stakeholders from agile developers
to the keepers of highly tuned legacy
applications that don’t play nicely in a
public cloud.
Other elements such as security are also
evolving to serve this hybrid IT position.
One of the most critical changes is the
emergence of a zero trust security model.
In simple terms, zero trust does away with
the assumption that all access from within
the corporate network is trusted and instead
verifies everything.
This shift makes multi-cloud access
management critical and modern
enterprises are deploying secure access
technologies such as single sign on (SSO)
and software defined perimeter (SDP) to
simplify the process.
SDP aids this by separating the control
plane of user authentication and access
with the data plane connecting users and
applications. Although not a new concept,
it has only been within the last few years
that it has started to rise in popularity with
analyst firms predicting strong 35% CACG
over the next five years – in part fuelled by
the needs of hybrid IT.
Integrating security controls that span on-
premise and cloud is also a major trend.
This has led to deeper support for open
standards for exchanging authentication
and authorisation data between parties.
Standards such as Security Assertion Mark-
up Language (SAML) and OAuth (Open
Authorisation) have gained more traction
over the last few years and will become
increasingly critical for delivering a zero
trust future.
Data centres and cloud providers need to be
aware of this shift and be able to support
this switch towards zero trust to remain a
valuable part of a hybrid IT ecosystem that
looks to be with us for the foreseeable future.
