Docker – an open platform for distributed applications for sysadmins and developers

How to define Docker?

Docker is an open platform for developers and sysadmins to build, ship, and run any application anywhere. It include a portable, lightweight runtime and packaging tool called Docker Engine and a cloud service for sharing applications and automating workflows called Docker Hub. 

Docker lets you to assemble quickly apps from components and eliminate the friction between development, QA, and production environments. 

What benefits do developers receive when using Docker?

Docker lets developers build any app in any language using any toolchain. The app is completely portable and can run anywhere. By starting with one of the 13,000+ apps available on Docker Hub, developers can get going quickly. Docker Hub also allows developers to automate their build pipeline and share artifacts with collaborators through public or private repositories.

With Docker, developers can build and ship higher-quality applications faster.

What benefits do sysadmins receive when using Docker?

With Docker, sysadmins can provide standardized environments for their development, QA, and production teams and eliminate differences in OS distributions and underlying infrastructure. Due to standardizing on the Docker Engine, sysadmins are given flexibility in where workloads run. Importantly, with Docker sysadmins can deploy and run any app on anywhere, reliably and quickly.

What are advantages and disadvantages of a Proprietary System and an Open Platform?

Choosing the right type of software is necessary for running a business as efficiently as possible in the global marketplace. Generally, you have one of two choices choosing a software platform for business purposes or even creating a website. One choice is proprietary software trademarked and likely requiring you to obtain or purchase a license while one choice is open-source software which is free software that you can download and pay no licensing fees to use. Using them has advantages and disadvantages. 

Advantages

With a proprietary-software system, you will be able to utilize the software company's customer service department for troubleshooting and setup purposes. Proprietary software may have more features that appeal to the business owner and is generally adjusted to meet a market need. 

Often, open-source software is cheaper or free. Additionally, it is widely distributed. Therefore, if you have any question, you can ask and gain help from a large number of users on the Internet via forums or other information sources. Often fast bug and security fixes are available for open-source software when problems arise

Expense

One of the big drawbacks of a proprietary-software package is expense. Proprietary-software users will generally charge a licensing fee to the software company that needs to take advantage of its product because the software company needs to sell its product to survive. This licensing fee can be fairly expensive, especially compared to open-source software. If open-source software requires any fees, they are usually required for the software itself not necessarily for ongoing licensing maintenance.

Developer

Compared to open-source software, proprietary software makes business owners too heavily dependent on the developer. It is another drawback of proprietary software. Only own programmers and developers understand the code that makes the software work. Generally, the licensee will not be able to turn to other business owners and users for help with the product.

Adaptability

Generally, proprietary software products make it difficult to adapt to changes in the marketplace. However, open-source software tends to be much quicker to adapt to these types of changes and often provides the business owner with more flexibility. Sometimes proprietary developers slowly offer fixes for any bugs that their software may have.
