Questions.
3
What Are Containers?

• Containers ensure that all software run
  appropriately when moved between various
  computing environments
• Development
• Testing
• Staging
• Production
• It could also mean software moving from premise
  to Cloud or even onto virtual machines

4
What Makes Up a Container?
5
What is Docker?

• Docker provides containers automating operating
  system virtualization for both Linux Windows
• It completely circumvents the need to create
  maintain virtual machines

6
What Entices the Programmers?
7
How is it Different from a Virtual Machine?

• Like virtual machine docker does not create an
  operating system
• Dockers use the running Linux Kernel and only
  require the application along with its
  dependencies to be package
• This significantly reduces the size of the
  package and improves the performance

8
Who is Using Docker in Their IT Practices?
9
What is Docker Used For?

• Simplifying Configuration
• Code Management
• Development Productivity
• Application Isolation
• Server Consolidation
• Debugging
• Rapid Development

10
Do Dockers Have Their Own Pros Cons too?

• It is obvious that there are going to be the
  flips flops for a technology as critical as
  this
• A reality check does not put down the programmers
  of custom java development

11
Advantages of Docker

• Container size is within tens of MB where as the
  VM can take up several gigabytes
• Containers are less resource consuming compared
  to VM
• Container provisioning hardly takes any time
• Containers enable easy allocation of resources to
  process
• Containers greatly reduce the time required for
  development, testing and deployment
• Testing is much easy as there is no difference in
  local and production environment
• Containers are quite cost-effective solution.
• Dockers are great option for microservices,
  DevOps and continuous deployment

12
Disadvantages of Docker

• The containers can have serious security issues
  as the containers have a common kernel and other
  different components of the host OS
• Docker can be functional for Windows, Mac OS and
  Linux, but it uses a virtual machine to run on
  non-Linux platform
• The monitoring solution offered by stats command
  of Docker is very limited
