DevOps & DevOps Lifecycle

 DevOps:

DevOps is a term that refers to the combination of software developers (dev) and operations personnel (ops). It is defined as a software engineering technique that strives to combine the activities of software development and software operations teams by promoting a collaborative and shared responsibility culture.

  • When compared to traditional methods, DevOps combines development and operations to boost software development and delivery efficiency, speed, and security.
  • DevOps is the combination of two words, one is Development and the other is Operations.
  • DevOps helps an organization's ability to offer apps and services more quickly. It also enables firms to better service their clients and compete more effectively in the market.

DevOps Lifecycle:

DevOps refers to the agile interaction that exists between operations and development. It is a method that is followed by the development team and operational engineers from the beginning to the end of the product's life cycle.

There are seven faces phases in DevOps Lifecycle:

  • Continuous Development
  • Continuous Integration
  • Continuous Testing
  • Continuous Monitoring
  • Continuous Feedback
  • Continuous Deployment
  • Continuous Operations

CONTINUOUS DEVELOPMENT:

Several DevOps practices, including continuous integration, continuous testing, continuous delivery, and continuous deployment, are included in the continuous development method for software development.

  • This phase mainly involves the planning and coding of the software.
  • There are no DevOps tools that are required for planning.

CONTINUOUS INTEGRATION (CI):

The process of automating the integration of code changes from several contributors into a single software project is known as continuous integration (CI).

Continuous Integration is the main stage of the entire DevOps lifecycle. Building code includes not just compilation but also unit testing, integration testing, code review, and packaging.

  • Continuous integration ensures continuous feedback.
  • CI helps to reduce the project backlog.
  • CI helps to decrease code review time and makes the project code more homogenous.
  • CI helps to prevent merge conflicts, challenging issues, duplicate code, and inconsistent coding techniques.

What are the Best Continuous Integration Tools?

The best Continuous Integration Tools are given below:

  • Jenkins
  • TeamCity
  • Bamboo
  • Buddy
  • GitLab CI
  • Circle Cl

CONTINUOUS TESTING (CI):

Continuous testing in DevOps refers to software testing that occurs at all stages of the development life cycle. The purpose of continuous testing is to evaluate software quality as part of a continuous delivery process by testing early and frequently.

Many stakeholders are involved in continuous testing, including the development team, DevOps team, Quality assurance (QA) team, and operational employees.

  • It saves a lot of time and effort for executing the tests instead of doing them manually.
  • Removes the disconnect between development, testing, and operations.

What are the best Continuous Testing Tools?

The best Continuous Testing Tools list is given below:

  • Katalon Studio
  • Selenium
  • Appium
  • Eggplant
  • Watir
  • Tosca
  • Testsigma
  • RFT (Rational Functional Tester)
  • Unified Functional Tester
  • TestComplete

CONTINUOUS MONITORING (CM):

Also known as Continuous Control Monitoring (CCM).

The technique of detecting risks to the security and compliance standards of a software development cycle and architecture is known as continuous monitoring. Typically, continuous monitoring begins before the software is released to production.

  • System downtime is significantly reduced
  • Performance errors are detected earlier
  • It maintains the security and availability of the service

The CM notifies the relevant teams of the mistakes made during the manufacturing phase. When these issues are found, they are then investigated by the appropriate parties.

Types of Continuous Monitoring

The types of Continuous Monitoring are:

Infrastructure Monitoring: Tools and processes for monitoring the networks, hardware, software, and data centers that are required to offer goods and services.

Infrastructure Monitoring Tools:

  • Nagios
  • Prometheus

Application Monitoring: Tools and procedures for monitoring the functionality and performance of applications that have been released in a production setting.

Application Monitoring Tools:

  • Datadog
  • Splunk

Network Monitoring: Tools and procedures for monitoring network activity and its many servers, firewalls, routers, and switches, as well as for spotting security concerns on the network

  • Wireshark
  • Nmap-Network Mapper

CONTINUOUS FEEDBACK:

Continuous feedback is critical to enhancing DevOps operations. While tools can allow feedback loops, DevOps teams must still remove needless noise and assess progress regularly.

The application development process is constantly enhanced by assessing the results of software activities. This is accomplished by establishing a key period of continual feedback between operations and the creation of the future edition of the present software application.

What are the best Continuous Feedback Tools?

The best Continuous Feedback Tools list is given below:

  • Jira Service Management
  • Parlor

CONTINUOUS DEPLOYMENT (CD):

Continuous Deployment (CD) is the pipeline's last stage, referring to the automated release of any developer changes from the repository to production. Continuous Deployment ensures that each update that goes through the production stages gets delivered to end users.

What are the best Continuous Feedback Tools?

The best Continuous Feedback Tools list is given below:

  • Ansible
  • Urban {Code}
  • Jenkins
  • Puppet
  • AWS DodeDeploy
  • DeployBot
  • GitLab
  • Bamboo Deploy

CONTINUOUS OPERATIONS (CP):

All DevOps operations are predicated on continuity with complete automation of the release process, allowing the business to continuously accelerate the total time to market.

  • Continuous operations are continuing and maintained activities inside a firm or organization in the case of a business disruption.
  • The advantages of continuous operations include increased productivity, cheaper manufacturing costs, and better quality control.
  • Continuous operations include limitations such as expensive capital costs and limited output flexibility.
  • Continuous operations also describe companies that operate 24/7.

DESCRIPTION:

If you want to build better software faster, DevOps is the answer. When compared to traditional methods, DevOps combines development and operations to boost software development and delivery efficiency, speed, and security.

Oracle Database Server Architecture: Overview

Image
  Memory Structures There are three major structures in Oracle Database server architecture: memory structures, process structures, and storage structures. A basic Oracle database system consists of an Oracle database and a database instance. The database consists of both physical structures and logical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting access to logical storage structures. The instance consists of memory structures and background processes associated with that instance. Every time an instance is started, a shared memory area called the System Global Area (SGA) is allocated and the background processes are started. Processes are jobs that work in the memory of computers. A process is defined as a “thread of control” or a mechanism in an operating system that can run a series of steps. After starting a database instance, the Oracle software associates the instance with ...
