+
+1. **dev and ops separation of concerns** create application container images at build/release time rather than deployment time, thereby decoupling applications from infrastructure
+
+{{< image src="/images/learning-path/intro-kubernetes/containers/c1_l3_1.png" width="100%" align="center" alt="DevOps" >}}
+
+2. **continuous development, integration, and deployment** provides for reliable and frequent container image build and deployment with quick and efficient rollbacks – due to image immutability
+
+{{< image src="/images/learning-path/intro-kubernetes/containers/c1_l3_2.png" width="100%" align="center" alt="Mutable vs Immutable" >}}
+
+3. **environmental consistency across dev, test, and prod** runs the same on a laptop as it does on an on-premises server, virtualized server, and in the cloud
+
+4. **OS distribution and cloud portability** runs on Ubuntu, RHEL, CoreOS, on major public clouds, on-premises, and anywhere else
+
+5. **resource utilization and isolation benefits** higher efficiency and density due to better utilization and predictable application performance due to isolation
+
+6. **loosely coupled, distributed, elastic microservices** applications are broken into smaller, independent pieces and can be deployed and managed dynamically – not a monolithic stack running on one big single-purpose machine
+
+7. **agile application creation and deployment** increased ease and efficiency of container image creation compared to VM image use
+
+8. <strong>application-centric management</strong> raises abstraction level:
+   <ul>
+     <li>from running applications on an OS using virtual hardware</li>
+     <li>to running applications on an OS using logical resources</li>
+   </ul>

+
+Many people have a complex job building, testing, and running systems based on old concepts and technology in today's IT — the results you can see below (Experiences we want to change!). Modern ways to build, test, and run IT systems are not adopted as broadly as possible. Hence, a lot of pain is still out there that we could ease by changing IT processes and utilizing the new ways.

+
+<h2 class="chapter-sub-heading">Traditional Deployment</h2>
+
+Early on, organizations ran applications on physical servers. There was no way to define resource boundaries for applications in a physical server, and this caused resource allocation issues. For example, if multiple applications run on a physical server, there can be instances where one application would take up most of the resources, and as a result, the other applications would underperform. A solution for this would be to run each application on a different physical server. But this did not scale as resources were underutilized, and it was expensive for organizations to maintain many physical servers.
+
+<h2 class="chapter-sub-heading">Virtualized Deployment</h2>
+
+As a solution, virtualization was introduced. It allows you to run multiple Virtual Machines (VMs) on a single physical server's CPU. Virtualization allows applications to be isolated between VMs and provides a level of security as the information of one application cannot be freely accessed by another application. Virtualization allows better utilization of resources in a physical server and allows better scalability because an application can be added or updated easily, reduces hardware costs, and much more. With virtualization, you can present a set of physical resources as a cluster of disposable virtual machines. Each VM is a full machine running all the components, including its own operating system, on top of the virtualized hardware.
+
+<h2 class="chapter-sub-heading">Container Deployment</h2>
+
+Containers are similar to VMs, but they have relaxed isolation properties to share the Operating System (OS) among the applications. Therefore, containers are considered lightweight. Similar to a VM, a container has its own file system, share of CPU, memory, process space, and more. As they are decoupled from the underlying infrastructure, they are portable across clouds and OS distributions.

+
+As often in IT, great "new" ideas and concepts are recycled or borrowed from others. So it happened that the shipping industry was a big inspiration for optimizing IT infrastructure operations more than two decades ago.
+
+The concept of a container to standardize the packing of goods, make them universal to handle and transport on different means of transportation to improve efficiency and reduce the transportation costs was a real success story for the transportation industry.
+
+Replication of success is always desirable and sparked a new way of operating IT infrastructures indifferent of application on development, testing, or production.
+
+Container Technology in the shipping industry Instead of thinking up a separate way of shipping for each product, placing the goods in steel containers designed for pickup by the crane on the dock and fit into the ship is a more efficient way to do transport at scale.
+
+{{< image src="/images/learning-path/intro-kubernetes/containers/c1_l2_1.png" width="100%" align="center" alt="A Container Ship" >}}
+
+In streamlining the processes and the loading of the goods in standardized containers, the goods can be moved as one unit in a space-saving and cost-effective manner.
+
+Container Technology in the IT industry Computer container technology in the IT industry addresses similar challenges to steel containers in the shipping industry:
+
+<ul>
+  <li>increase compatibility</li>
+  <li>reduce dependencies</li>
+  <li>develop, deploy and operate easier</li>
+</ul>
+
+{{< image src="/images/learning-path/intro-kubernetes/containers/c1_l2_2.png" width="50%" align="center" alt="Docker" >}}
+
+In streamlining the processes and the apps' packaging in containers, deploying and running apps as one unit become a more performant and resource-effective process.
