COMPARING CONTAINERS AND VIRTUAL MACHINES




Containers and virtual machines have similar resource isolation and allocation benefits -- but a different architectural approach allows containers to be more portable and efficient.


VIRTUAL MACHINES:

Virtual machines include the application, the necessary binaries and libraries, and an entire guest operating system -- all of which can amount to tens of GBs.



CONTAINERS:

Containers include the application and all of its dependencies --but share the kernel with other containers, running as isolated processes in user space on the host operating system. Docker containers are not tied to any specific infrastructure: they run on any computer, on any infrastructure, and in any cloud.

Use of Static Imports in Java with Example

The main reason behind the static import feature in java5 is to reduce the unnecessary reference of class name to call static methods/fields. package   import.static.test ; import   static   java.lang.Integer.MAX_VALUE ; import   static   java.lang.Integer.MIN_VALUE ; import   static   java.lang.System.out ; public   class  StaticImportExample  {      public   static   void  main ( String  args [])   {                //without Static import          System . out . println ( "Maximum value of int variable in Java without "  + "static import : "   +  Integer . MAX_VALUE ) ;          System . out . println ( "Minimum value of int variable in Java without "  + static import : "  +  Integer . MIN_VALUE ) ;             ...

Shell Scripting - Best Practices

Best Practices   Shell Scripting  : Most programming languages have a set of "best practices" that should be followed when writing code in that language. However, I have not been able to find a comprehensive one for shell scripting so have decided to write my own based on my experience writing shell scripts over the years. A note on portability : Since I mainly write shell scripts to run on systems which have Bash 4.2 installed, I don't need to worry about portability much, but you might need to! The list below is written with Bash 4.2 (and other modern shells) in mind. If you are writing a portable script, some points will not apply. Needless to say, you should perform sufficient testing after making any changes based on this list :-) Here is my list of best practices for shell scripting (in no particular order): Use functions Document your functions Use  shift  to read function arguments Declare your variables Quote all parameter expansions...
