(an English portmanteau blending development and operations, the latter as in put into
production or deployment) is a software development methodology that aims at
communication, collaboration and integrationbetween developers and operations.
Devops means synergy between corporate culture, practices and tools. It aims to provide a mindset and an arsenal of tools to develop applications and services with maximum agility. This approach allows for the evolution and improvement of products at greater speed than traditional software development and infrastructure management processes.
Facebook, Spotify and Netflix are just some of the web giants that have understood the benefits of this methodology.
The approach aims to merge in a single unit the development (Dev) and operations (Ops) team, which remains active throughout the life cycle of the application: development, testing and delivery, with the advantage that each team member acquires global, rather than domain- specific knowledge.
The team always aims to achieve greater efficiency and operational independence, which is why all automation processes are at the base of the Devops approach.
The ability to minimize manual tasks has the benefit of reducing errors and waste. This is we use techniques and tools that include: Container, Continuous Integration, Continuous Delivery, Infrastructure as code, Microservices and Build pipeline.
Adapt to change
The Agile manifesto promotes the ability to adapt to change over following a plan. To be agile and respond to market and context changes, it is necessary to use processes that are able to adapt quickly and frequently, and which allow the application of metrics capable of measuring the effectiveness of actions. Continuous delivery techniques and microservice architectures adapt perfectly to these scenarios.
Increase the frequency of releases and achieve results in less time
Innovation goes through continuous evolution and data analysis. Improving speed of release allows fixing bugs faster, as well as promptly integrating new features and gathering feedback from users. In a competitive market, speed and time to market are crucial parameters. This is why continuous integration and continuous delivery practices to automate software rapid build and release procedures are so important.
Better communication and greater organizational effectiveness
The approach focuses on communication, knowledge-sharing and interactions between two worlds that until now have almost always been separate: development and operations. Sharing responsibilities and integrating workflows helps streamline communications, reduce inefficiencies and design Cloud-native applications that take into account the infrastructure on which they will run.
Programmatic scalability and cost optimization
Infrastructure scalability is essential to guarantee the expected business results; whether upwards to handle traffic peaks, or downwards to reduce costs. This is why it is important for the software to manage infrastructures easily and with maximum automation. By managing infrastructures as code (IaC), it is possible to optimize the whole stack: from development to testing and production environments.
Develop secure and reliable software
The approach guarantees speed, but also security and compliance. Development and test environments accurately reflect production environments and the code is automatically tested for each build by unitary and functional testing. In a continuous integration regime, application advances are frequent and small, making testing faster and more effective. In addition, it is easier to identify which implementation has produced the problem at hand.
All the DevOps procedures help companies to innovate with greater speed, automating as much
as possible all the manual processes that can be delegated to machines, and optimizing the
infrastructure. This is why automation is one of the cornerstones of the DevOps approach, and
we have put a lot of effort into creating a suite of tools to guarantee these results.
Below, we offer an overview of the DevOps practices we adopt in our projects.
Continuous integration is a practice we consolidated in all our development processes. The method consists in frequent alignment, even many times a day, of portions of code from development environments to the repository (GIT in our case). The build and test generation is completely automated. This method allows to immediately bringing out bugs, improving the quality of the artifact and being able to release new features faster during production.
Continuous delivery is the natural extension of continuous integration techniques and ensures that the software is always in deployable state, exploiting the Continuous integration pipelines and generating artifacts, namely, the compiled and production-ready version of the application and of any service related to it.
Microservice architectures are an application design pattern that allows the
separation of each software component into a separate, self-contained service,
such as a Docker container, which communicates with other components based
on a shared API. The goal is to divide large and complex systems into simple
and independent projects.
This approach allows for a more streamlined orchestration, freedom in programming languages (because each service is potentially independent) and effective scalability.
Infrastructures as code
This is an approach for building and maintaining automated and dynamic software infrastructures. The software is able to programmatically provision the infrastructure through APIs provided by vendors, such as Google Cloud or Amazon AWS. The other advantage is being able to ensure that each development and test environment is a copy of the production, therefore standardized, thus eliminating the classic problems of deployment on production environments.
