DevOps (Dev + Ops) – The buzz that never ENDS!

There’s a massive culture shift occurring in enterprise IT operations and software development departments. But many businesses still operate in traditional methods, discouraging innovation and making it challenging to meet end-user expectations. To stay competitive, enterprises need to meet end users’ expectations, rapidly respond to consumer demands and organizations must ensure that their software, services, and applications integrate efficiently in the cloud.

To stay competitive, all organizations are adopting DevOps approach. DevOps is the union of people, process, and products to enable continuous delivery of value to our end users. The contraction of “Dev” and “Ops” refers to replacing siloed Development and Operations to create multidisciplinary teams that now work together with shared and efficient practices and tools. Essential DevOps practices include agile planning, continuous integration, continuous delivery, and monitoring of applications.

The original idea of DevOps is to smooth out the interaction between development and operations. The ‘DevOps’ movement is about having everyone understand how the entire system works, and everyone being able to express what their underlying business value is. Developers are all about innovation, developing something cool and new every day whereas Sysadmins are focused on never letting the site go down. Before DevOps, developers weren’t worried about the site uptime and vice versa. DevOps helps to overcome these limitations and ensures secure, frequent and timely product deliveries. It also ensures that there is communication between marketing, customer service, operations, quality and other teams.

Tips to Achieve DevOps:

  1. Shorten Your Cycle Time:
    When you adopt DevOps practices, you shorten your cycle time by working in smaller batches, using more automation, hardening your release pipeline, improving your telemetry, and deploying more frequently.
  1. Optimize Validated Learning:
    The more frequently you deploy, the more you can experiment, the more opportunity you have to pivot or persevere and to gain validated learning each cycle.
  1. Continuous Integration:
    Continuous Integration drives the ongoing merging and testing of code, which leads to finding defects early. Other benefits include less time wasted on fighting merge issues and rapid feedback for development teams.
  1. Continuous Delivery:
    Continuous Delivery of software solutions to production and testing environments helps organizations quickly fix bugs and respond to ever-changing business requirements.
  1. Version Control, Usually With Git:
    Git enables teams located anywhere in the world to communicate effectively during daily development activities as well as to integrate with software development tools for monitoring activities such as deployments.
  1. Agile planning and lean project management:
    These techniques are used to plan and isolate work into sprints, manage team capacity, and help teams quickly adapt to changing business needs. A DevOps Definition of Done is working software collecting telemetry against the intended business objectives.
  1. Monitoring and Logging:
    Continuous Monitoring and Logging of running applications including production environments for application health and customer usage, helps organizations form a hypothesis and quickly validate or disprove strategies. Rich data is captured and stored in various logging formats.
  1. Public and Hybrid Clouds:
    Public and Hybrid Clouds have made the impossible easy. The cloud has removed traditional bottlenecks and helped commoditize infrastructure. Whether you use Infrastructure as a Service (IaaS) to lift and shift your existing apps, or Platform as a Service (PaaS) to gain unprecedented productivity, the cloud gives you a datacenter without limits.
  2. Infrastructure as a Code (IaaC):
    IaaCis a practice which enables the automation and validation of creation and teardown of environments to help with delivering secure and stable application hosting platforms.
  1. Microservices:
    Microservices architecture is leveraged to isolate business use cases into small reusable services that communicate via interface contracts. This architecture enables scalability and efficiency.
  1. Azure Container Service (AKS):
    Containers are the next evolution in virtualization. They are lightweight compared to virtual machines allowing for faster hydration and can be easily configured from files.

But DevOps takes Time

There is no quick solution to create entire DevOps environment; it takes time to change policies, attitudes, and practices. Just like going to the gym, adopting new methods is likely to hurt at first. The more you exercise the new methods, the easier they will become. If followed through, DevOps adoption can dramatically save your organization significant amounts of time and money while boosting efficiency at all levels.
