Leveraging DevOps Services: Development, Testing, and Delivery

Leveraging DevOps Services: Development, Testing, and Delivery

2020-08-31 DevOps 0

Enterprise IT organizations need to continuously roll out innovative new features into their platform-as-a-service offering with just the right features to achieve faster time to market with no defects and low cost. 

DevOps is an approach that helps you achieve speed and quality by enabling collaboration between lines of business, development team, testers, and IT operations team with shared and integrated toolsets throughout development, integration, and staging phases of application delivery. To add on, DevOps today are complementing the agile methodologies, lean practices in the context of a system-oriented approach.

DevOps service providers help many global IT enterprises to establish DevOps Processes by leveraging the right stack of tools and technologies.

How to Implement DevOps?

1. DevOps as a Culture

DevOps is not a technology rather a culture itself, an organization can gain its fruits when DevOps is started being absorbed as organizations culture, to implement DevOps culture it needs to gell and collaborate well with the team participating in Development and operations of their product. 

Similar to Agile, DevOps believes in continuous collaboration, deployments, testing, monitoring, and feedback that can be achieved by involving the OPS team in the early stage of development and with their active participation until the production releases.

2. Automate Everywhere

The basic fundamental of DevOps is to implement the automation in all the stages delivery, right from the code verification to deployment, which includes code integration, builds, testing, deploying, verifying the deployed builds. This automation accelerates all the stages of software delivery so that developers get feedback and impact of their changes fast which helps to speed up an overall time to market.

3. Continuous Code Integration

Continuous Integration (CI) addresses the developer group in the DevOps lifecycle. Here the key focus is to have seamless error-free builds with best techniques & standards of version controls that are adopted and then picked up for the deployment in the specified environments. The challenge is selecting the right toolset that works for your needs. Hudson, Jenkins, Bamboo, are some of the tools used for continuous integration.

Code Integration Tools: Git, SVN, Hudson, Jenkins, Bamboo

4. Continuous Code Testing

Testing is another important part of the development lifecycle that certifies the quality of the product that is delivered to the end customer. DevOps emphasis on automating all the types and phases of testing. The goal of continuous testing is to provide fast and continuous feedback about the level of business risk in the latest build which is used to determine if the software is ready to progress through the delivery pipeline at any given time. Tools like Maven, Selenium, Cucumber, and Robot Framework are widely used tools for testing.

Code Testing Tools: Python Framework, Selenium, Maven, Robot Framework

5. Continuous Orchestration

Applications are typically multi-tier in their architecture, which means that each application has dependencies that need to be managed properly. Hence, containers are created for fast and reliable deployment of application components on any underlying infrastructure. Orchestration will take care of the timing of container creation by order of dependency, as well as all of the necessary configurations to allow the containers to communicate and pass the required runtime properties to one another.

Orchestration Tools: Docker, Kubernetes

6. Dynamic Configuration and Deployment

Configuration management tool helps you to keep environments consistent throughout the software development process, from the developer’s laptop until production across all the stages of the delivery pipeline. The commonly used tools are Chef, Ansible, Vagrant, Puppet.

Continuous deployment is the core of DevOps. The continuous deployment follows continuous delivery and deploys automatically all changes that passed the automated tests to production. Some of the popular tools for deployment are Capistrano, Electric Flow, Octopus Deploy, Continuum.

Dynamic Deployment Tools: Ansible, Chef, Puppet, Vagrant

7. Continuous Monitoring

Continuous monitoring of the entire DevOps lifecycle will ensure development and operations teams collaborate to optimize the user experience every step of the way. Monitoring enables to collect and analyze data is testing environments. Tools like Librato, Nagios, Zabbix, Sensu, Logstash generate the data for the team which shows whether the performance is improved or became worse and helps to take corrective measures for improving the performance.

Monitoring Tools:  Nagios, Sensu, Icinga2, Librato
