Openness, flexibility, and
speed to distributed deployments have been top drivers of the steady growth of container-based
solutions. Now, IT operators are looking to increase automation, built-in
intelligence, and robust management as they seek container-enabled hybrid cloud
and multicloud approaches for data and workloads.
Stay with us now as we examine
the rapidly evolving containers innovation landscape and learn about the next
chapter of automated and extensible IT infrastructure solutions with Mark Linesch, Vice President
of Technology Strategy in the CTO Office and Hewlett
Packard Labs at Hewlett
Packard Enterprise (HPE).
Welcome to BriefingsDirect, Mark.
Mark Linesch: Thanks,
Dana. It’s great to be here.
Gardner: Let’s
look at the state of the industry around containers. What
are the top drivers for containers adoption now that the technology has matured?
Containers catch on
Linesch: The
history of computing, as far back as I can remember, has been about abstraction;
abstraction of the infrastructure and then a separation of concern between the
infrastructure and the applications.

| Linesch |
It used to be it was all bare
metal, and then about a decade ago, we went on the journey to virtualization. And
virtualization is great, it’s an abstraction that allows for certain amount of
agility. But it’s fairly expensive because you are virtualizing the entire
infrastructure, if you will, and dragging along a unique operating system (OS)
each time you do that.
So the industry for the last
few years has been saying, “Well, what’s next, what’s after virtualization?” And
clearly things like containerization are starting to catch hold.
Why now? Well, because we are
living in a hybrid cloud world, and we are moving pretty aggressively toward a
more distributed edge-to-cloud world. We are going to be computing, analyzing,
and driving intelligence in all of our edges -- and all of our clouds.
Things such as performance-
and developer-aware capabilities, DevOps,
the ability to run an application in a private cloud and then move it to a
public cloud, and being able to drive applications to edge environments on a harsh
factory floor -- these are all aspects of this new distributed computing
environment that we are entering into. It’s a hybrid estate, if you will.
Containers have advantages for
a lot of different constituents in this hybrid estate world. First and foremost
are the developers. If you think about development and developers in general,
they have moved from the older, monolithic and waterfall-oriented approaches to
much more agile
and continuous
integration and continuous
delivery models.
And containers give developers
a predictable environment wherein they can couple not only the application but
the application dependencies, the libraries, and all that they need to run an application
throughout the DevOps lifecycle. That means from development through test,
production, and delivery.
Containers carry and encapsulate
all of the app’s requirements to develop, run, test, and scale. With bare metal
or virtualization, as the app moved through the DevOps cycle, I had to worry
about the OS dependencies and the type of platforms I was running that pipeline
on.
Developers’ package deal
A key
thing for developers is they can package the application and all the
dependencies together into a distinct manifest. It can be version-controlled
and easily replicated. And so the developer can debug and diagnose across different
environments and save an enormous amount of time. So developers are the first
beneficiaries, if you will, of this maturing containerized environment.
And increasingly in this more
hybrid distributed edge-to-cloud world, I can run those containers virtually
anywhere. I can run them at the edge,
in a public cloud, in a private cloud, and I can move those applications
quickly without all of these prior dependencies that virtualization or bare
metal required. It contains an entire runtime environment and application, plus
all the dependencies, all the libraries, and the like.
The third area that’s interesting
for containers is around isolation. Containers virtualize the CPU, the memory,
storage network resources – and they do that at the OS level. So they use
resources much more efficiently for that reason.
Unlike virtualization, which includes your entire OS as well as the application, containers run on a single OS. Each container shares the OS kernel with other containers so it's lightweight, uses less resources, and spins up instantly.
Unlike virtualization, which includes your entire OS as well as the application, containers run on a single OS. Each container shares the OS kernel with other containers, so it’s lightweight, uses much fewer resources, and spins up almost instantly -- in seconds versus virtual machines (VMs) that spin up in minutes.
When you think about this fast-paced,
DevOps world we live in -- this increasingly distributed hybrid estate from the
many edges and many clouds we compute and analyze data in -- that’s why
containers are showing quite a bit of popularity. It’s because of the business
benefits, the technical benefits, the development benefits, and the operations
benefits.
Gardner: It’s been
fascinating for me to see the portability and fit-for-purpose containerization benefits,
and being able to pass those along a DevOps continuum. But one of the things
that we saw with virtualization was that too much of a good thing spun out of
control. There was sprawl,
lack of insight and management, and eventually waste.
How do we head that off with
containers? How do containers become manageable across that entire hybrid
estate?
Setting the standard
Linesch: One way
is standardizing the container formats, and that’s been coming along fairly
nicely. There is an initiative called The
Open Container Initiative, part of the Linux Foundation, that develops to the
industry standard so that these containers, formats, and runtime software
associated with them are standardized across the different platforms. That
helps a lot.
Number two is using a standard
deployment option. And the one that seems to be gripping the industry is Kubernetes. Kubernetes is an open
source capability that provides mechanisms for deploying, maintaining, and scaling
containerized applications. Now, the combination of the standard formats from a
runtime perspective with the ability to manage that with capabilities like Mesosphere or Kubernetes
has provided the tooling and the capabilities to move this forward.
Gardner: And
the timing couldn’t be better, because as people are now focused on as-a-service
for so much -- whether it’s an application, infrastructure, and increasingly,
entire data centers -- we can focus on the business benefits and not the
underlying technology. No one really cares whether it’s running in a virtualized
environment, on bare metal, or in a container -- as long as you are getting the
business benefits.
Linesch: You
mentioned that nobody really cares what they are running on, and I would
postulate that they shouldn’t care. In other words, developers should develop,
operators should operate. The first business benefit is the enormous agility
that developers get and that IT operators get in utilizing standard
containerized environments.
This is very important when
you think about IT
composability in general because the combination of containerized
environments with things like composable
infrastructure provides the flexibility and agility to meet the needs of
customers in a very time sensitive and very agile way.
Gardner: How
are IT operators making a tag team of composability and containerization? Are
they forming a whole greater than the sum of the parts? How do you see these
two spurring innovation?
Linesch: I have
managed some of our R and D centers. These are usually 50,000-square-foot data
centers where all of our developers and hardware and software writers are off doing
great work.
And we did some
interesting things a few years ago. We were fully virtualized, a kind of private
cloud environment, so we could deliver infrastructure-as-a-service (IaaS)
resources to these developers. But as hybrid cloud hit and became more of a mature
and known pattern, our developers were saying, “Look, I need to spin this stuff
up more quickly. I need to be able to run through my development-test pipeline
more effectively.”
And containers-as-a-service
was just a super hit for these guys. They are under pressure every day to
develop, build, and run these applications with the right security,
portability, performance, and stability. The containerized systems -- and being
able to quickly spin up a container, to do work, package that all, and then move
it through their pipelines -- became very, very important.
From an infrastructure operations
perspective, it provides a perfect marriage between the developers and the
operators. The operators can use composition and things like our HPE Synergy
platform and our HPE OneView
tooling to quickly build container image templates. These then allow those
developers to populate that containers-as-a-service infrastructure with the
work that they do -- and do that very quickly.
Gardner: Another
hot topic these days is understanding how a continuum will evolve between the
edge deployments and a core cloud, or hybrid cloud environment. How do
containers help in that regard? How is there a core-to-cloud and/or core-to-cloud-to-edge
benefit when containers are used?
Gaining an edge
Linesch: I
mentioned that we are moving to a much more distributed computing environment,
where we are going to be injecting intelligence and processing through all of
our places, people, and things. And so when you think about that type of an
environment, you are saying, “Well, I’m going to develop an application. That
application may require more microservices or more modular architecture. It may
require that I have some machine learning (ML)
or some deep learning analytics as part of that application. And it may then
need to be provisioned to 40 -- or 400 -- different sites from a geographic
perspective.”
When you think about edge-to-cloud,
you might have a set of factories in different parts of the United States. For
example, you may have 10 factories all seeking to develop inferencing and analyzed
actions on some type of an industrial process. It might be video cameras
attached to an assembly line looking for defects and ingesting data and analyzing
that data right there, and then taking some type of a remediation action.
Then, how do I package up all
of those application bits, analytics bits, and ML bits? How do I provision that
to those 10 factories? How do I do that in a very fast and fluid way?
That’s where containers really shine. They will give you bare-metal performance. They are packaged and portable – and that really lends itself to the fast-paced delivery and delivery cycles required for these kinds of intelligent edge and Internet of Things (IoT) operations.
Gardner: We
have heard a lot about AIOps and
injecting more intelligence into more aspects of IT infrastructure,
particularly at the June HPE
Discover conference. But we seem to be focusing on the gathering of the
data and the analysis of the data, and not so much on the what do you do with
that analysis – the execution based on the inferences.
It seems to me that containers
provide a strong means when it comes to being able to exploit recommendations
from an AI engine and then doing something -- whether to deploy, to migrate, to
port.
Am I off on some rough tangent?
Or is there something about containers -- and being able to deftly execute on
what the intelligence provides -- that might also be of benefit?
Linesch: At
the edge, you are talking about many applications where a large amount of data
needs to be ingested. It needs to be analyzed, and then take a real-time action
from a predictive maintenance, classification, or remediation perspective.
We are seeing the benefits of containers really shine in these more distributed edge-to-cloud environments. At the edge, many apps need a large amount of data ingested. The whole cycle time of ingesting data, analyzing it, and taking some action back is highly performant with containers.
And so containers spin up very quickly. They use very few resources. The whole cycle-time of ingesting data, analyzing that data through a container framework, taking some action back to the thing that you are analyzing is made a whole lot easier and a whole lot performant with less resources when you use containers.
Now, virtualization still has a
very solid set of constituents, both at the hybrid cloud and at the intelligent
edge. But we are seeing the benefits of containers really shine in these more
distributed edge-to-cloud environments.
Gardner: Mark,
we have chunked this out among the developer to operations and deployment, or
DevOps implications. And we have talked about the edge and cloud.
But what about at the larger
abstraction of impacting the IT organization? Is there a benefit for
containerization where IT is resource-constrained when it comes to labor and
skills? Is there a people, skills, and talent side of this that we haven’t yet
tapped into?
Customer microservices support
Linesch: There
definitely is. One of the things that we do at HPE is try to help customers
move into these new models like containers, DevOps, and continuous integration
and delivery. We offer a set of services that help customers,
whether they are medium-sized customers or large customers, to think
differently about development of applications. As a result, they are able to
become more agile and microservices-oriented.
Microservice-oriented
development really lends itself to this idea of containers, and the ability
of containers to interact with each other as a full-set application. What you
see happening is that you have to have a reason not to use containers
now.
Our customers are moving to a
more continuous integration-continuous development approach. And we can show
them how to manage and operate these types of environments with high automation
and low operational cost.
Gardner: A lot
of the innovation we see along the lines of digital transformation at a
business level requires taking services and microservices from different
deployment models -- oftentimes multi-cloud, hybrid cloud, software-as-a-service
(SaaS) services, on-premises, bare metal, databases, and so forth.
Are you seeing innovation
percolating in that way? If you have any examples, I would love to hear them.
Linesch: I am
seeing that. You see that every day when you look at the Internet. It’s a
collaboration of different services based on APIs. You collect a set of
services for a variety of different things from around these Internet endpoints,
and that’s really as-a-service. That’s what it’s all about -- the
ability to orchestrate all of your applications and collections of service
endpoints.
Furthermore, beyond
containers, there are new as-a-function-based, or serverless, types of
computing. These innovators basically say, “Hey, I want to consume a service
from someplace, from an HTTP endpoint, and I want to do that very quickly.”
They very effectively are using service-oriented methodologies and the model of
containers.
One of the principles that we are focused on is moving the compute to the data -- as opposed to moving the data to the compute. And the reason for that is when you move the compute to the data, it’s a lot easier, simpler, and faster -- with less resources.
I recommend that companies not
stand on the sidelines but to get
busy, get to a proof of concept with containers-as-a-service. We have a lot
of expertise here at HPE. We have a lot of great partners, such as Docker, and
so we are happy to help and engage.
Gardner: And a big thank you as well to our audience for joining this BriefingsDirect Voice of the Innovator interview. I’m Dana Gardner, Principal Analyst at Interarbor Solutions, your host for this ongoing series of Hewlett Packard Enterprise-sponsored discussions.
We are seeing a lot of
innovation in these function-as-a-service
(FaaS) capabilities that some of the public clouds are now providing. And we
are seeing a
lot of innovation in the overall operations at scale of these hybrid cloud
environments, given the portability of containers.
At HPE, we believe the cloud
isn’t a place -- it’s an experience. The utilization of containers provides a
great experience for both the development community and the IT operations
community. It truly helps better support the business objectives of the
company.
Investing in intelligent innovation
Gardner: Mark,
for you personally, as you are looking for technology strategy, how do you
approach innovation? Is this something that comes organically, that bubbles up?
Or is there a solid process or workflow that gets you to innovation? How do you
foster innovation in your own particular way that works?
Linesch: At HPE,
we have three big levers that we pull on when we think about innovation.
The first is we can do a lot
of organic development -- and that’s very important. It involves
understanding where we think the industry is going, and trying to get ahead of
that. We can then prove that out with proof of concepts and incubation kinds of
opportunities with lead customers.
We also, of course, have a
lever around inorganic innovation. For example, you saw recently an acquisition
by HPE of Cray to turbocharge the next generation of high-performance
computing (HPC) and to drive the next generation of exascale computing.
The third area is our partnerships
and investments. We have deep
collaboration with companies like Docker, for example. They have been a
great partner for a number of years, and we have, quite frankly, helped to
mature some of that container management technology.
We are an active member of the
standards organizations around the containers. Being able to mature the
technology with partners like
Docker, to get at the business value of some of these big advancements is
important. So those are just three ways we innovate.
Longer term, with other HPE core
innovations, such as composability and memory-driven computing, we believe that
containers are going to be even more important. You will be able to hold the
containers in memory-driven
computing systems, in either Dynamic
random-access memory (DRAM) or storage-class
memory (SCM).
You will be able to spin them up
instantly or spin them down instantly. The composition capabilities that we
have will increasingly automate a very significant part of bringing up such systems,
of bringing up applications, and really scaling and moving those applications to
where they need to be.
One of the principles that we are focused on is moving the compute to the data -- as opposed to moving the data to the compute. And the reason for that is when you move the compute to the data, it's a lot easier, simpler, and faster with less resources.

This next generation of
distributed computing, memory-driven computing, and composability is really ripe
for what we call containers in microseconds. And we will be able to do
that all with the composability tooling we already have.
Gardner: When
you get to that point, you’re not just talking about serverless. You’re talking
about cloudless. It doesn’t matter where the FaaS is being generated as long as
it’s at the right performance level that you require, when you require it. It’s
very exciting.
Before we break, I wonder what
guidance you have for organizations to become better prepared to exploit containers,
particularly in the context of composability and leveraging a hybrid continuum
of deployments? What should companies be doing now in order to be getting
better prepared to take advantage of containers?
Be prepared, get busy
Linesch: If
you are developing applications, then think deeply about agile development
principles, and developing applications with a microservice-bent is very, very
important.
If you are in IT operations,
it’s all about being able to offer bare metal, virtualization, and containers-as-a-service
options -- depending on the workload and the requirements of the business.
We have quite a bit of on-boarding
and helpful services along the journey. And so jump in and crawl, walk, and run
through it. There are always some sharp corners on advanced technology, but
containers are maturing very quickly. We are here to help our
customers on that journey.
Gardner: I’m
afraid we’ll have to leave it there. We have been exploring how openness, flexibility,
and speed to distributed deployments have been top drivers for the steady
growth of container-based solutions. And we have learned how IT operators now are
looking to increase automation, built-in intelligence, and robust management as
they seek to take advantage of container-enabled hybrid cloud models.
