WHAT IS DEVOPS AND WHY IT IS USED AND EXPLAIN ADVANTAGES AND DEVOPS TOOLS

 DEVOPS:

1.DEVOPS IS A COMBINATION OF SOFTWARE DEVELOPMENT AND IT OPERATION.

2.MELDING(MERGING) OF THESE TWO DISCIPLINES IN ORDER TO EMPHASTIC COMMUNICATION,COLABERATION,COHESSION BETWEEN THE TRADITIONALLY.SEPERATE DEVELOPER AND IT OPERATION TEAMS.

AGILE MODEL:

1.IN CASE OF AGILE MODEL APROJECT WILL DIVIDE INTO MULTIPLE MODULES,EACH MODULE WILL DEVELOP IN A CYCLIC ORDER.

ADVANTAGES:

1.SHORT A DEVELOPMENT CYCLE.

2.WIDER MARKET WINDOWS.

3.EARLY CUSTOMER FEEDBACK.

4.CONTINUOUS DEVELOPMENT.

EXTENDING THE AGILE MOVEMENT:

1.AGILE S/W DEVELOPMENT PAVED THE WAY,STEERING AWAY FROM THE WATERFALL METHOD OF SOFTWARE DEVELOPMENT TOWORDS A CONTINUOUS DEVELOPMENT CYCLE.

2.BUT THIS DIDNOT INCLUDE THE OPERATION SIDE,SO WHILE DEVELOPMENT COULD BE CONTINUOUS ,DEVELOPMENT WAS STILL WATERFALL ORIENTED.

DEV+OPS:

1.GOAL OF DEVOPS:

1.IMPROVE DEPLOYMENT FREQUENCY.

2.ACHIVE FASTER TIME TO MARKET.

3.LOWER FAILURE RATE OF NEW RELEASES.

4.SHORTEN LEAD TIME B/W FIXERS.

5.IMPROVE MEAN TIME TO RECOVERY.

DEVOPS TOOLS:

CICD-CONTINUOUS  INTEGRATION CONTINUOUS DEVELOPMENT.

VCS-VERSION CONTROL SYSTEM.

RCS-REVISION CONTROL SYSTEM.

1.VEGRANT:IT IS USED TO CREATE SERVERS BUT NOT MORE THAN 100.IT CREATES MACHINE IN 1 MINUTE .IT IS A LOCAL MACHINE.

2.CLOUD:IT IS USED TO CREATE SERVER OR MACHINE MORE THAN 100.I.E AWS,AZER,GOOGLE.

3.HOST:DIRECTLY INSTALLING OS FOR THIS WE NEED TO PURCHASE SERVER SO INFASTRUCTURE AND MAN POWER WILL BE NEEDED.

4.VM-WAVE:FOR ONE MACHINE WE NEED TO SPEND 30 MINUTES .IT IS A TIME TAKING PROCESS.
