Khalid will share on emerging container technologies and their role in supporting an agile cloud-native application development model. He will discuss the basics of containers compared to traditional virtualization, review use cases, and explore the open-source container management ecosystem.

3. A standard way to package an application and
all its dependencies so that it can be moved
between environments and run without
changes.
Containers work by isolating the differences
between applications inside the container so
that everything outside the container can be
standardized.

Containers and VMs Solve Different Problems
Containers are lighter and perform better:
• Portability: VM (Gigabytes) vs. Container
(Megabytes), VMs are constraint to Hypervisor and
hardware-emulation
• Performance: Containers can boot and restart in
seconds, compared to minutes for virtual machines.
And no extra overhead of a hypervisor and guest
OS makes containers consume less CPU and
memory.
• Management cost: Each VM requires a full
functional operating system, and then extra
management for them.
Great advantage to use containers in:
• DevOps
• Batch computing
• Lightweight PaaS
• Microservices

Cloud Native Applications are being built with Microservices
Using Containers

Cloud Native applications are
characterized by the following:
• DevOps and continuous integration /
continuous delivery methods
• User experience centric principles
• Use of microservice architecture, and
API-centric approach to applications
• Multisource data collection mechanisms
from sources such as social media
streams or IOT sensors.
• Built-in analytics capabilities intended to
help inform/develop process
• Low-risk technology investments that
avoid lock-in Source: Gartner

Container Management Platforms are Emerging
• Container Management Platforms (CMPs) are also known as container managers,
container orchestration engines, container orchestration platforms and containers-
as-a-service (CaaS) platforms.
• They help enterprises address the challenges of deploying containers. These
platforms let administrators monitor, manage, secure, and scale containers similar
to how they treat existing servers and virtual machines.

What is Kubernetes?
• Container orchestrator
• Runs and manages containers
• Supports multiple cloud and bare-metal
environments
• Inspired and informed by Google's experiences
and internal systems
• 100% Open source, written in Go
• Manage applications, not machines
• Rich ecosystem of plug-ins for scheduling,
storage, networking

Kubernetes Concepts
A group of co-located containers
| 10
A service defines a set of pods and
a means by which to access them,
such as single stable IP address and
corresponding DNS name.
A volume is a directory, possibly
with some data in it, which is
accessible to a Container as part of
its filesystem.
A label is a key/value pair that is
attached to a resource, such as a
pod, to convey a user-defined
identifying attribute.
A replication controller ensures that
a specified number of pod replicas
are running at any one time.
