What is Docker?<\/h4>\n
Virtualization using virtual machines (VMs) was a game changer when first introduced. It allowed businesses to take full advantage of their network resources by giving them the ability to efficiently run multiple OSs and apps on the same host. When deploying new hardware, VMs significantly cut down the time it took to set up devices, allowing teams to configure resources in minutes instead of days.<\/span><\/p>\n But VMs have limitations. Aside from having to boot up an OS, each new addition requires virtual resources to be allocated (such as RAM), which can quickly strain your system when running multiple VMs. When porting, VMs typically cause compatibility issues, too, and they can\u2019t share data volumes.<\/span><\/p>\n Docker is equally as revolutionary as VMs, and has<\/span> been rapidly adopted by organizations<\/span><\/a> since its initial release in 2013.<\/span><\/p>\n Docker takes virtualization in a different route, using something called containerization. Docker containers are lightweight and automate deployment of applications so they can work in different environments (i.e. on different machines). Each container is essentially its own software package that contains the dependencies to run an application, such as code, configuration files, processes, networking info, and sometimes even pieces of an OS.<\/span><\/p>\n So instead of running separate desktop environments, as with resource-hungry VMs, Docker containers run on a single system kernel and allow you to maintain isolated applications that work properly \u2014 regardless of what machine they\u2019re running on.<\/span><\/p>\n Modern OOB networks employ an array of sophisticated tools, like those that support monitoring, management, and automation. Using Docker containers means that you can deploy applications and know that they\u2019ll work on any resource, because Docker works on the client side. Docker can also act as a service and be deployed onto any server. And because all application dependencies are contained directly on the image, management is easier as well.<\/span><\/p>\n On a high level, using Docker containers brings these advantages to OOB:<\/strong><\/p>\n On top of all these advantages, Docker improves network management by giving you three major benefits.<\/span><\/p>\n VMs allow you to run any platform \u2014 along with its unique configuration \u2014 on your infrastructure. However, VMs come with drawbacks because they require significant resources in order to work properly. Essentially, running a VM means running a separate, virtual desktop environment on your hardware. And with each VM you run, your device must allocate RAM and other resources, which can be expensive and lead to unstable performance.<\/span><\/p>\n Docker containers are much more lightweight, and you can run multiple containers using only a single OS kernel. Containers use less memory than VMs, they boot faster (because they don\u2019t have to spool up an OS), and they can share and reuse data volumes. In a nutshell, containers make virtualization simple, highly efficient, and easy to configure, which significantly reduces the overhead associated with virtualization when compared to using VMs.<\/span><\/p>\n Before VMs, setting up new hardware took days because of the tedious, manual configuration that was required. With VMs, devices could be configured in minutes (and remotely), but IT teams still lost time due to the need to boot up an OS for each VM.<\/span><\/p>\n Using Docker containers, fresh resources can be configured in seconds because there\u2019s no need to boot up an OS. Multiple containers running on the same hardware can run isolated applications, such as those containing configuration data and automation scripts, to help you rapidly deploy resources to your network. Simply create a container for the appropriate job.<\/span><\/p>\n When it comes to business continuity, traditional approaches call for assigning a single purpose site to disaster recovery efforts. This means that resources sit idle at this site, because most of the time your organization is not focused on recovering from disaster. In essence, a traditional approach leaves disaster recovery as an afterthought, which means that managing and maintaining its infrastructure is costly and complex.<\/span><\/p>\n However, by using Docker containers, you can transform disaster recovery to be just another stage in the integration and development pipeline. This means that your recovery infrastructure is expanded from a single site to an entire region (or your entire organization), because containers allow you to utilize more resources more frequently.
