   <p>Another advantage of this is when a vulnerability is discovered within a particular node, the hierarchical tree allows the user to verify all other nodes that are impacted by this vulnerability. In order to create images, it is important to look at an example. Docker is a container engine. Docker uses a Docker file to create images. Containers are used to isolate processes within the OS. </p>

   <p>Application containers can be thought of as a form of virtualization similar to Virtual Machines (VM). However instead of virtualizing the entire stack, containers virtualize at an operating system level.<ref>What are Containers and their benefits  |  Google Cloud. (n.d.). Retrieved from <i>[https://cloud.google.com/containers/.]</i></ref> Because of this they are extremely lightweight, enabling them to use only a fraction of the memory and processing as only a single OS Kernel is needed to host multiple containers.</p>

   <p class="expand mw-collapsible-content">Application containers facilitate a service oriented architecture (SOA). In an SOA the application is decomposed in into several services. With containers, individual services can be launched as different containers. With clustering this enables the ability to scale up a solution. The proper orchestration tools are required to properly enable scaling. Container orchestration tools manage the lifecycle of containers, a software development team will use them to provision and deploy containers, check redundancy and availability, and to move a container from one host to another. </p>

   <p class="expand mw-collapsible-content">Monolithic applications can also be deployed as containers. As a monolithic container is essentially a single–tiered application a single instance will be deployed as a single container. This differs from the microservice and SOA approach as a container will represent a single service of that application. With containers, in order to scale up a monolithic application multiple instances of the application and thus several containers need to be deployed. When using Docker, updates to the application can be deployed as docker images which is faster and network efficient. Also since containers can be spun up faster, creating new application instances a quicker process.</p>

   <p>Two major vendors of application container technology are Docker and CoreOS. Docker was introduced first, and as a result is used more widely in the industry.  Application containers are of most benefit to large companies. It has been four years since Docker’s initial foray into the market, and a  survey conducted by Datadog in 2016 revealed that adoption of Docker had increased 30%+ over the previous year. What is important to note about this statistic is that these companies are using the software in production rather than development, which suggests that companies are using containers as a long-term approach and not simply on a trial basis</p>
