Increasingly, organizations are finding that they have

and innovation from their existing cloud strategies.
That’s because they have mainly focused For many organizations, unlocking the next level

ADOPTING THE

Organizations can take advantage of the distinctive, inherent
characteristics of the cloud platform such as bi-directional
innovation, faster speed to value, more rapid new-product ideation,
and greater elasticity, scale and resiliency with cloud native.

In today’s technology era, cloud is the execution platform; to the left are DevOps
processes, which are driven by Agile development—all of which are a result of today’s
microservices architectures, which are driven and invoked by business events.

11THE ELEMENTS OF CLOUD-NATIVE COMPUTING
Cloud
Cloud is an extremely flexible delivery platform. It can support many
different architectural and deployment styles, from big, monolithic
systems, to large, virtual-machine deployments, to nimble clusters
of containers, to large farms of serverless functions.
Cloud is flexible enough to carry most
of the IT architectures from the last 20 years.
Again, however, to get the maximum business
benefits and value from the cloud, one should
understand that the platform itself is only one
part of the overall cloud-native picture.

APPROACH TO MODULAR AND
FLEXIBLE OPEN PLATFORMS
Cloud native delivers scale, resiliency and agility—both for the business
and developers—that are almost impossible to achieve with pre-cloud architectures.
