Use of Docker in Various Applications


The time from when Docker arose as great technology, software developers are continuously humming their praises for this marvelous technology. Docker has made it easy to design multi-component application which spreads across cloud environment. The container technology is a standard kind of ‘virtualization’ technique that is capable of isolating services and applications from one another within the virtual machines. Dockers enable the applications to run on same operating system like Linux OS, using its resources.

Majority of government organizations as well as software developing companies look not just into advantages of container technology like Docker but the operational performance and speed with reduced cost are the major factors that decide their interest for the Docker technology. The Docker containers are really light-weight when compared to Virtual Machines, which is another major reason for this technology adoption by major companies.

In this chapter, we will discuss various use cases for Docker from leading software companies, business application areas of Docker and the final conclusion why an enterprise must choose Docker.

Docker Use Cases in Various Leading Companies

The Docker technology is being rapidly adopted by major leading companies of the world due to its optimistic developer experiences, image portability and convenient and easy deployment. The containers in Docker is simple to build and easy for local deployment on both conventional systems as well as Cloud services. Dockers are easy to move locally.

Majority of companies look at Docker as the best solution for developing cloud based services or micro-applications. Cloud Provider needs faster environment for iterating their applications. In cases where Docker represents micro-services or a broad deployment application, Docker must be tied along with workflow managers. This is mainly true for conditions where some components get developed on Cloud and then undergo on-premise deployment and even vice versa.


The local and fast delivery service of eBay is eBay now. The Senior Architect of Google, Ted Dziuba believes that Docker is very helpful for continuous process integration. The leading online commercial company, eBay makes use of Docker for implementing an effective, automated connectivity from developer’s machine to testing and quality assurance. There are various building clusters at eBay Corporation. These clusters are partitioned depending on various factors like need to run various OS flavors (mainly Ubuntu and RHEL), conflicting of software versions, linked application dependency and the hardware specialties.

If eBay uses Mesos, a single cluster is made to run in heterogeneous workload, without special clusters. Docker, the container technology offers best solution for isolating various dependencies in container without depending upon host machine setup on where slave of Mesos runs. This thus provides help for operating on a single cluster. Slave
attributes can easily handle exceptional hardware requirement. To conclude, Docker helps in maintaining standard images of host in cluster, avoiding introduction of various Mesos flavors in wide range of combinations. At the same time, Docker is capable of handling different building dependencies within the container.


Spotify is the music streaming service company of Sweden which has improved rapidly in recent days, later its launching in 2006. Container technology of Docker is best way for Spotify, the streaming-music service provider. This music streaming company is using container technology largely. Docker has modified the way of deploying services and for running data centres. By using Docker containers for deployment and testing, we can accelerate the continuing delivery processes. The internal team of Spotify which switched towards Helios, a Docker-driven platform is enjoying high-productivity experience within few weeks of adoption.

One of the services of Spotify namely ‘view-aggregation service’ is a best fit for the container technology of Docker. This service is responsible to spoll data from data centres of Spotify which stores information about playlists of individual which includes track lists, artist names, and album images. Grouping of these services within containers
enables Spotify as instead of depending on clients who are needed for sending separate request for each service to get needed information from data centres, Spotify can do deployment of container clusters which contain a group of services and so there is need for sending multiple requests. And finally, the application is not bulky and heavy, says
Simon Cohen, the team leader of Spotify.


The European based bank, ING makes use of Docker for updating more than 1400 various applications daily. The speed is really important for us and we achieve this by continuous delivery system. In ING information technology service, all of us are developers and want something better, which means better coding and better customer
satisfaction and the container technology, Docker is major component of our policy for implementing all our services, mainly faster, said Henk Holk, the chief architect of this banking sector.


Inside the IBM ‘development and operations’ portfolio, UCD or UrbanCode Deploy arranges for deploying various applications. UCD enables an application focussed perspective of world, which allows deployment of application for co-ordinating various component deployments using inventory tracking. UrbanCode deployment platform of IBM has extended its support to Docker registries, containers and also IBM container services for Bluemix through community plug-ins.

Conditions During Which IBM’s Urbancode Accompaniments Docker

  • When a deployment technician wants in co-ordinating deployment of multiple Docker containers over Cloud Service Providers or Docker hosts.
  • When the deployment technician wants to co-ordinate deployment of docker container sets as a portion of huge conventional deployment of application processes. This is mainly helpful while converting a huge application into microservice sets.
  • When an operational engineer requires validation sets, test processing sets or certification sets along deployable images within the environment.
  • When the operation engineer wants automation of images between cloud registry and Docker registry.

Bleacher Report

The Amazon Web Service Elastic Beanstalk is very convenient way of using services needed for scaling and deploying web applications that are built in Ruby, combined with other major languages. By combining Docker with Elastic Beanstalk, the application developers create the ability of building and testing applications on their local machines and then deployment of code that is tested to AWS cloud seamlessly. The promising service that Docker containers achieves on Elastic Beanstalk will enable the developers in experimenting with Docker’s rapidly emerging technological pairing. At scaling, Bleacher Report is very fast which helps in maintaining it as one of the leading
sports websites around the world. Docker entitles the developers with speed, ownership and consistency for building better applications for websites, says Senior Director of Bleacher, Tung Nguyen.


Gilt is an online web store which has created 7 large applications in the website into four hundred smaller bits which makes it easy to update. Docker aids in putting production platform into operation, creating it faster and convenient for making changes that in turn helps the engineers to give high focus on product building. The CTO and founder of GILT hailed Docker and confirmed its adoption for his company in his online report.


Google adopted Docker for its cloud usage. A streamlined distribution of Canonical Linux Ubuntu has made way for running Docker containers. Google is the passionate and whole-hearted supporter of virtualization based on container technology. In the month of this June, Google has released Kubernetes, an open source for container management. Ubuntu Core, designed for providing just the important components to run workload of Linux on cloud. Recently, a previous preview edition of Ubuntu Core was released with name ‘Snappy’. This recent edition has discarded majority of the programs and libraries which were present in standard Linux dispersions and which were not needed for cloud usages.


The technical team of Yelp has finally made decision that future technology would definitely spin around container technology called ‘Docker’ and not the virtual machine. The Docker can give solution for certain service deployment problems of Yelp as it provides ability for developers in managing their own set of containers and also to deal
dependency problems and packaging without spending time for image building. Docker is being an essential part of next generation service management and testing of Yelp. The Docker features like dependency isolation and fast spinning of containers has paved way for Yelp developers to minimize their development cycles and enhance speed of testing by 4 times more than original.

New Relic

The New Relic has extended its server support for Docker which has given a complete view of whole environment. Docker helps New Relic to explore and fetch the actual performances of server and also the image views. Docker has made an impression for new service deployment and building of new services for New Relic. Docker provided
more independence and great focus on creating a software masterpiece for developer team of New Relic when they released the New Relic Insights. Docker has also helped this company in delivering its services at much faster rate, meeting rigorous schedules as believed by Director, Nic Benders.

BBC News

The use of Docker based container technology has helped BBC to face all challenges in CI or continuous integration platform and also with unexpected workloads such as “side-load” which were essential for the overall working. Docker has simplified the environment of testing and building software within containers. Docker is also believed
to save much time of developers. Docker is the perfect fit for BBC news. The company needed rapidly changing testing fields which could be easily developed using Dockers.

How Docker Aids in Business Development

Docker has passed across major IT enterprises over the past one year as the leading and fast-growing container technology ever. This open source technology has created impact on all leading companies in developer applications. Docker has the capability to allow developers in assembling applications from reused pieces. For example: Lego-like
blocks that are capable of running on Linux servers and other machines. The advocates of Docker believe that it is capable of supplying agile workflow and high speed in the present scenario where numerous web applications and mobile applications get updated daily.

The leading company like Google were starters for using this container technology. Container technology has been prevailing for years but the credit of simplifying and commercialising it goes to Docker Inc in 2013. Along with DevOps and Agile, the container technology like Docker has made its way into enterprises. Nowadays, the companies are seeking technology to duplicate software development life cycles in Silicon Valley-like methods. Though Docker was not of much importance until the beginning of the year 2014, it has occupied a great place in software  development by theending of 2014.

Docker enables the application developers in chunking out a code or pieces of code and perform testing quickly with launching of incremental attributes, the application development of enterprises will modify, Ben Golub, the CEO of Docker reported to CIO. Suppose a huge monolithic application working by thousand people can possibly be split into hundred tiny services, each with workgroup of 3 persons which can iterate and modify independently, it is possible with Docker providing faster speed, creativity and cost effective- as told by Golub.

At a rough rate, 3-4 millions of developers around the world now use Docker. The major companies like ING group, Groupon Inc, Gilt Inc, etc have already adopted this technology. Docker Inc was offering free software in the beginning but now it has hosted both on-premise and paid services for its software. Docker Inc is very busy with network, monitoring and security built-up with great money infusion which is going to happen in near future.

The CEO of Docker provided answers to few queries that would arise in our minds. Listed below are some of his explanations.

How Docker technology would change software development method in companies?

In a conventional method, nearly a thousand member team will be working on building a monolithic application that are tightly coupled and server-specific. If there exists a very long and retarded cycle releases in months or even weeks, the developers would find it difficult in fast software update as any small change would break the application. Using Docker, it is possible for application assembling as like you build from Legos, using which micro-services can easily be integrated and interchanged yet remain compatible to one another and work perfectly across many servers. The building compartment could be any service that is separated from the reporting segment using a single sign-up
segment. These modules can easily be reused across various applications. Docker enables developers in placing any application into digital counterpart of container shipping, which denotes that it is easily portable across any servers on cloud or onpremise and also across any operating platform, and still the application runs consistently.

How Docker plays a leading role in emerging integration and deployment models that are rapid, like DevOps and Agile?

If any of your application has portability across various platforms without causing breakage, then all your operations are highly agile. Docker aids in creating multiplecontainer applications on local machine for testing. It manages code pipeline and development. Docker also enables continuous integration of pipeline and streamlines it in a “DevOps” environment.

Lets Conclude Discussion

Docker, an open-source container technology has taken over server virtualization field, providing what is seen as quicker alternative for running complete VM (Virtual Machines) over the hypervisors. With recent Docker release, the building team behind Docker is focusing on creating Docker capable for enterprise usage. The result is that container technology could be faster, utilizing less system resources than that of virtual machines, if the developer is willing on sticking to a single environment that that provide shared operating system.

The creation of a complete virtual machine or VM may consume several minutes for creating and launching but Docker’s container technology can be started in just few seconds. Docker also offers high performance rates for contained applications. This is pretty much faster while comparing to applications that run on a virtual machine which faces operation overhead of using hypervisors. The application that runs on Docker is two times faster than the applications that are running inside a VM or virtual machine.

Many containers can be bundled in a single server as there is no operating system duplication for individual applications. One of the main advantages of Docker is portability across different environments. Containers of Docker can either run on simple metal server or above virtual machines. They can either run on cloud or on-premises. These features have led to its influence on software developments and the familiar use cases for containers are software application development and deployment. The programmers can compile applications and keep them inside the Docker container after which the application gets moved over different environments. These applications resemble capsules placed inside containers.

Unlike the VMs, Docker never creates a tank of applications. Docker is light-weighted and thus offers higher flexibility reducing bulk resources. The same Docker container is capable of running on both AWS and the cloud, which is not possible by virtual machines. Docker creates a neat configuration and deployment environment for its users.

Google, the online leader made announcement in 2013 that the cloud environment of it was providing support for Docker, the open source technology. But this announcement mostly went unnoticed among the huge stack of software developers around the world.

Ten months after Google’s Docker adoption, Amazon Web Services (AWS), VMWare, Microsoft and IBM succeeded Google’s decision. At the end of 2014, Docker technology had moved from complete abstrusely to hottest initiator of many software businesses across the globe.

Docker is nothing but a magic spark in software-ruling world. It was an unavoidable bothersome before invention of Docker in moving a particular application from your desktop’s development stage to other machine for testing, in enhancing productivity and availability.

If you wished to build an application for AWS (Amazon Web Services) which can be ported either to Microsoft or Google’s cloud, a well defined and bulk team should be needed to face all technical troubles. Though the container technology is available for years, Docker has given a new meaning for it by making it quite simpler. There was a
recent study by RightScale on Docker which concluded that out of 930 software professional organizations, thirteen percentages of them were using Docker already right from its first year of release. The remaining thirty percentages of the organizations were under planning to use Docker in near future.
