DevOps vs Agile

April 11th, 2019 Operating System

DevOps is a philosophy which endorses cooperation between Development plus Operations Team. Agile software expansion is a method for software expansion under which necessities and solutions grow. To understand the difference between these two let’s first understand what they are!

What is DevOps

DevOps represents a customary practice that systematizes the progressions within software development and IT teams, so that they can develop and test the software along with its release faster and extra reliably.. The assured benefits comprise increased faith, quicker software releases, and ability to solve serious issues rapidly, and better accomplish unforeseen work.
Companies that integrate DevOps practices catch more work done very simply. With a single group containing cross-functional participants all working in cooperation, DevOps organizations can provide maximum speed, innovation and functionality. It overcomes many challenges of waterfall model.

Following are some of the features of DevOps:

  • Enhanced deployment frequency
  • Quicker time to market
  • Lower catastrophe rate of novel releases;
  • Reduced lead period between fixes;
  • Earlier mean time to reclamation of loss (at the time of a different release crashing or disabling the existing system).
  • Cloud Provision: Various cloud service model are used such as SAAS etc.
  • Configuration: To make the runtime environment work in a proper manner configuration management tool is used.

DevOps Lifecycle consists of different stages viz. development, integration, testing, monitoring and virtualization.

What is Agile

Agile is used for software development where requirements as well as solutions grow through the collaborations of various team members from different functional teams and their end users. Adaptive planning along with evolutionary development and early delivery are main focus of agile development. Continual improvement policy inspires speedy and flexible reaction to alterations.
Most agile improvement methods work by breaking the product into minor increments that diminish the quantity of up-front development and scheme. Iterations are short interval frames also called time boxes that normally last till four weeks. Each iteration includes a cross function group working in different areas viz.: plan, analysis, designing, coding, testing, and finally acceptance testing. When iteration ends a working product is confirmed to stakeholders. This reduces overall risk and permits the product to acclimate to changes speedily. An iteration or restatement might not enhance enough functionality to warranty a release in the market, but the objective is to have an obtainable release also with minimal errors at the end of every iteration. Numerous iterations might be mandatory to issue a product or new features. Functioning software is the chief measure of development.

Following are key features of Agile Methodology

Scrum
Scrum is the most widespread way of presenting Agile due to its effortlessness and suppleness. Scrum highlights empirical response group self-management and determined to build correctly tested increments within small iterations. The advantage includes amplified visibility of project areas and how to accomplish them. This distinguishing features of Agile projects, pay toward the significance goal of bringing software on time.
Quality
Testing is combined throughout the development, enabling steady inspection of the operational product as it advances. This permits the product holder to make necessary changes.
Visibility
Development principles of Agile encourage user to give active involvement through the product’s development course. This provides outstanding visibility for important stakeholders, both the development’s progress plus the product itself, it also helps to ensure the prospects are effectively achieved.
Identification and tenacity of issues
Minor incremental statements made visible to the owner and product team over its development benefit to identify any matters early and make it stress-free to respond to alteration. The clear discernibility in agile development supports to guarantee that any necessary conclusions can be taken at the initial possible chance, while there is still interval for a material change to the outcome.
Agility
In Agile development, modification is accepted. Timescale is immovable and requirements arise and grow as the product is settled For this, it’s important to have a vigorously involved patron who understands this idea and makes the essential trade-off choices. They both pretty much sound the same.

How are Agile and DevOps different?

Feature DevOps Agile
Core concept More about management of end-to-end processes of engineering. More about management of complex projects.
Main focus End solution. Processes like sprints.
Main functionality Configuration management. Linking DevOps with Design thinking.
Alignments Aligns stability with Ops. Aligns business priorities with developments.
Bridge Bridge between various cross functional groups. Gap between groups is bridged with scrum calls.
Delivery Fast delivery using automation Streamlined delivery
Tools used Docker, configuration management, splunk etc. Kanban board, XP, scrum etc.
