What is devops ? 15 smart and powerful tools

Let’s understand what is devops ?

 

 

DevOps is a culture which promotes collaboration between Development and Operations Team to deploy code to production faster in an automatic & repeatable way. The word ‘DevOps’ could also be a mixture of two words ‘development’ and ‘operations.’

DevOps helps to increases an organization’s speed to deliver applications and services. It allows organizations to serve their customers better and compete more strongly within the market.

 

What-is-Devops-exactly

 

In simple words, DevOps are often defined as an alignment of development and IT operations with better communication and collaboration.

Why DevOps is Needed ?

Before DevOps, the event and operation team worked in complete isolation.
Testing and Deployment were isolated activities done after design-build. Hence they consumed longer than actual build cycles.
Without using DevOps, team members are spending an outsized amount of their time in testing, deploying, and designing instead of building the project.
Manual code deployment leads to human errors in production
Coding & operation teams have their separate timelines and are not in synch causing further delays.
There is a requirement to increase the speed of software delivery by business stakeholders. As per Forrester Consulting Study, Only 17% of teams can use delivery software fast enough. This proves the pain point.

So, I think you have now understood what is devops, right?

Now, lets check out main reasons for why DevOps is needed?

DevOps allows Agile Development Teams to implement Continuous Integration and Continuous Delivery. This helps them to launch products faster into the market.

Other Important Reasons Are:

1. Predictability: DevOps offers significantly lower failure rate of latest releases.

2. Reproducibility: Version everything so as that earlier version are often restored anytime.

3. Maintainability: Effortless process of recovery within the event of a replacement release crashing or disabling  this system.

4. Time to plug : DevOps reduces the time to plug up to 50% through streamlined software delivery. this is often often particularly the case for digital and mobile applications.

5. Greater Quality: DevOps helps the team to provide improved quality of application development because it incorporates infrastructure issues.

6. Reduced Risk: DevOps incorporates security aspects within the software delivery life cycle. It helps in reduction of defects across the life cycle.

7. Resiliency: The Operational state of the software is more stable, secure, and changes are auditable.

8. Cost Efficiency: DevOps offers cost efficiency within the software development process which is typically an aspiration of IT companies’ management.

9. Breaks larger code base into small pieces: DevOps is based on the agile programming method. Therefore, it allows breaking larger code bases into smaller and manageable chunks.

When to adopt DevOps?

DevOps should be used for large distributed applications like eCommerce sites or applications hosted on a cloud platform.

When not to adopt DevOps?

It should not be utilized during a mission-critical application like bank, power and other sensitive data sites. Such applications need strict access controls on the assembly environment, an thorough change management policy, access control policy to the data centers.

You understood what is devops, Now lets understand lifecycle of devops

 

 

DevOps is deep integration between development and operations. Understanding DevOps isn’t possible without knowing DevOps lifecycle.

Here could also be a quick information about the continual DevOps life-cycle:

  • Development

In this DevOps stage the event of software takes place constantly. during this phase, the entire development process is separated into small development cycles. This benefits DevOps team to hurry up software development and delivery process.

  • Testing

QA team use tools like Selenium to identify and fix bugs within the new piece of code.

  • Integration

In this stage, new functionality is integrated with the prevailing code, and testing takes place. Continuous development is simply possible because of continuous integration and testing.

  • Deployment

In this phase, the deployment process takes place continuously. it’s performed in such a fashion that any changes made any time within the code, shouldn’t affect the functioning of high traffic website.

  • Monitoring

In this phase, operation team will lookout of the inappropriate system behavior or bugs which are found in production.

DevOps Work Flow

 

 

Workflows provide a clear overview of the sequence during which input is provided. It also tells about actions are performed, and output is generated for an operations process.
Workflow allows the facility to separate and arrange jobs which are top-requested by the users. It also gives the facility to mirror their ideal process within the configuration jobs.

  • Plan: this is often often the a neighborhood of the project where you’re organizing the tasks, schedules and located out your project management tools. the thought is to plan tasks using the user story process from the agile methodology. Write tickets within the type of a user story will allow developers and Ops to understand what development must be done and why. a perfect user story as a what (who, where, trigger), a why and acceptance criteria. (Example: As a user, in my customer account, once I click on “option” I open a popup which i can change my name and first name).
  • Code: Here the developers do code development and code review. When the code is ready , they merge it. In DevOps practice, it is vital to share a code tool between Ops and developers teams like Github or Gitlab.
  • Build: This step is that the primary one toward automation. The goal here is to make the ASCII document into one desired format, compiling, testing and deploying during a specific place of the infrastructure. Once this step sets up the continual integration (CI) and delivery (CD) tools can check and verify the ASCII document from ASCII document Management and build it.
  • Test: the continual testing process reduces risks. Automatic tests confirm that no bugs are getting to be implemented in production. you’ve to implement testing tools in your workflow to form sure the only development quality for your software.
  • Release: The code has passed the testing (continuous integration) process and is ready to be deployed.
  • Deploy: The operational team is deploying the new feature in production. But as automation is one of the DevOps principles, it’s possible to line up continuous deployment.
  • Operate/ configure infrastructure: The Ops build or maintain a scalable infrastructure, infrastructure as code and check security issues and log management.
  • Monitor: The monitoring may be a crucial step because it allows to repair incidents faster and to form much better experience for your end-user.

As DevOps aims to significantly increase the satisfaction of your customers, naturally your teams start again the steps with a replacement feature for your software or application. that’s why we always draw the DevOps as an endless loop.

15 smart and powerful devops tools

 

What is devops and all available devops tools

Here you can see some of the favored tools for DevOps:

1. Git:  It is a version control system, and it lets teams collaborate on a project at the same time. Developers can track changes in their files, as well as improve the product regularly. Git is widely popular among tech companies. Many companies consider it is a must-have for their tech professionals.

You can save different versions of your code on Git. You can use GitHub for holding repositories as well. GitHub allows you to connect Slack with your on-going projects so your team can easily communicate regarding the project.You can save different versions of your code on Git. You can use GitHub for holding repositories as well. GitHub allows you to connect Slack with your on-going projects so your team can easily communicate regarding the project.

2. Jenkins:  DevOps are divided into different stages. For integrating them, you’d need to perform Continuous Integration (CI). Jenkins is the tool that can help you in that regard. Jenkins enables companies to boost their software development processes. Developers use Jenkins to test their software projects and add changes seamlessly.
This tool uses Java with plugins, which help in enhancing Continuous Integration. Jenkins is widely popular with more 1 million users. So also get access to a thriving and helpful community of developers.

3. Docker:  Docker is a containerization platform that packages your application and all its dependencies together in the form of a docker container to ensure that your application works seamlessly in any environment.

4. Container:  Container is a standardized unit which can be created on the fly to deploy a particular application or environment. It could be an Ubuntu container, CentOs container, etc. to full-fill the requirement from an operating system point of view. Also, it could be an application oriented container like CakePHP container or a Tomcat-Ubuntu container etc.

5. Kubernetes:  Kubernetes deserves a place on this DevOps tools list for obvious reasons. First, it is a fantastic container orchestration platform. Second, it has taken the industry by storm.
When you have many containers to take care of, scaling the tasks becomes immensely challenging. Kubernetes helps you in solving that problem by automating the management of your containers.
It is an open-source platform. Kubernetes can let you scale your containers without increasing your team. As it is an open-source platform, you don’t have to worry about access problems. You can use public cloud infrastructure or hybrid infrastructure to your advantage. The tool can also self-heal containers. This means it can restart failed containers, kills not-responding containers, and replaces containers.

6. Ansible:  Ansible is an open source IT configuration management (CM) and automation platform, provided by Red Hat. It uses human-readable YAML templates so as that users can program repetitive tasks to occur automatically, without learning a sophisticated language.

7. Chef:  Chef could also be a configuration management tool for handling machine setup on physical servers, virtual machines and within the cloud. Many companies use Chef software to manage their infrastructure including Facebook, Etsy, Cheezburger, and Indiegogo

8. Puppet:  Puppet is an open source DevOps systems management tool for centralizing and automating the configuration management process. it’s wont to configure, manage, deploy, and orchestrate various applications and services across the entire infrastructure of a corporation.

9. Nagios:  Nagios is an open source monitoring system for computer systems. It had been designed to run on the Linux OS and should monitor devices running Linux, Windows and Unix operating systems. Nagios software runs periodic checks on critical parameters of application, network and server resources.

10. SaltStack:  SaltStack is an orchestration and configuration management tool which allows the system administrators to perform automation of server management. SaltStack provides high-speed data connectivity and faster communication between the various systems present within the IT organization.

11. Bamboo:  Bamboo is analogous to Jenkins because it helps you in automating your delivery pipeline. The difference is of their prices. Jenkins is free, but Bamboo isn’t . Is bamboo worth paying for? Well, Bamboo has many functionalities which are found out beforehand. With Jenkins, you would’ve had to create those functionalities yourself. which takes tons of effort and time. Bamboo doesn’t require you to use many plugins too because it can do those tasks itself. it’s an excellent UI and it integrates with BitBucket and lots of other Atlassian products.

12. Vagrant:  It help to build and manage virtual machine environments. It lets you do all that in a single workflow. You can use it on Mac, Windows, as well as, Linux.
It provides you with an ideal development environment for better productivity and efficiency. It can easily integrate with multiple kinds of IDEs and configuration management tools such as Salt, Chef, and Ansible. Because it works on local systems, your team members won’t have to give up their existing technologies or operating systems. Vagrant’s enhanced development environments certainly make DevOps easier for your team. That’s why we have kept it in our DevOps tools list.

13. Prometheus:  Prometheus is a free software application used for event monitoring and alerting. It records real-time metrics in a time series database built using a HTTP pull model, with flexible queries and real-time alerting

14. Monit ELK (Elasticsearch, Logstash, Kibana):  Monit is a utility for managing and monitoring processes, programs, files, directories and file systems on a Unix system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations.

15. Splunk: Splunk is a software technology which is used for monitoring, searching, analyzing and visualizing the machine generated data in real time. It can monitor and read different type of log files and stores data as events in indexers. This tool allows you to visualize data in various forms of dashboards.
