Understanding
Linux
containers
Applications
are
getting
more
complex.
Demand
to
develop
faster
is
ever-­‐increasing.
This
puts
stress
on
your
infrastructure,
IT
teams,
and
processes.
Linux®
containers
help
you
alleviate
issues
and
iterate
faster—across
multiple
environments.

What
can
you
do
with
containers?
§ When
your
business
needs
the
ultimate
portability
across
multiple
environments
containers
might
be
the
easiest
decision,
ever.
§ You
can
deploy
containers
for
a
number
of
workloads
and
use
cases
big
to
small.

What
is
DOCKER?
With
DOCKER,
you
can
treat
containers
like
extremely
lightweight,
modular
virtual
machines.
And
you
get
flexibility
with
those
containers—you
can
create,
deploy,
copy,
and
move them
from
environment
to
environment.
§ The
software
"Docker”
is
containerization
technology
that
enables
the
creation
and
use
of Linux®
containers.
§ The open
source
Docker communityworks
to
improve
these
technologies
to
benefit
all
users—freely.
§ The
company,Docker Inc.,
builds
on
the
work
of
the
Docker community,
makes
it
more
secure,
and
shares
those
advancements
back
to
the
greater
community.
It
then
supports
the
improved
and
hardened
technologies
for
enterprise
customers.

How
does
Docker work?
The
Docker technology
uses
the
Linux
kernel
and
features
of
the
kernel,
like Cgroups and namespaces,
to
segregate
processes
so
they
can
run
independently.
This
independence
is
the
intention
of
containers-­‐the
ability
to
run
multiple
processes
and
apps
separately
from
one
another
to
make
better
use
of
your
infrastructure
while
retaining
the
security
you
would
have
with
separate
systems.
Docker,
provide
an
image-­‐based
deployment
model.

What
is
Kubernetes?
Kubernetes is
an
open-­‐source
system
for
automating
deployment,
scaling,
and
management
of
containerized
applications.
These
clusters
can
span
hosts
across public, private,
or hybrid
clouds.
