What is DevOps ?
Continuous Integration
- Continuous integration is a software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run.
- The key goals of continuous integration are to find and address bugs quicker, improve software quality, and reduce the time it takes to validate and release new software updates.
- Because you’re integrating so frequently, there is significantly less back-tracking to discover where things went wrong, so you can spend more time building features.
- Continuous Integration is cheap. Not integrating continuously is expensive. If you don’t follow a continuous approach, you’ll have longer periods between integrations. This makes it exponentially more difficult to find and fix problems. Such integration problems can easily knock a project off-schedule, or cause it to fail altogether.
Continuous Delivery
- Continuous delivery is a software development practice where code changes are automatically built, tested, and prepared for a release to production.
- Continuous Integration is the process of automating the build and testing of code every time a team member commits changes to version control.
- Higher quality. When developers have automated tools that discover regressions within minutes, teams are freed to focus their effort on user research and higher-level testing activities such as exploratory testing, usability testing, and performance and security testing. By building a deployment pipeline, these activities can be performed continuously throughout the delivery process, ensuring quality is built in to products and services from the beginning.
- Lower costs. Any successful software product or service will evolve significantly over the course of its lifetime. By investing in build, test, deployment and environment automation, we substantially reduce the cost of making and delivering incremental changes to software by eliminating many of the fixed costs associated with the release process.
Microservices
- The microservices architecture is a design approach to build a single application as a set of small services.
- Each service runs in its own process and communicates with other services through a well-defined interface using a lightweight mechanism, typically an HTTP-based application programming interface (API).
- Code for different services can be written in different languages (though many practitioners discourage it), which makes it Easy to understand and modify for developers, thus can help a new team member become productive quickly.
- Adopting microservices allows organizations to achieve greater agility and realize lower costs, thanks to the inherent granularity and reusability of what constitutes a microservice.
Infrastructure as code
- Infrastructure as code is a practice in which infrastructure is provisioned and managed using code and software development techniques, such as version control and continuous integration.
- With this, the knowledge of server provisioning, configuration management and deployment is no longer only with the systems admins. Even developers can easily engage in the activities, because they can easily write infrastructure code in the languages that they are familiar with.
- Most tools are even idempotent, which ensures that you can run the same configuration multiple times while achieving the same result.
- With the help of these tools and more, development and testing becomes simpler, as one can easily spin up a server and fully configure it even on their development box for use while developing. This eliminates breaking of the common server that is usually shared during development.
DevOps Process
-
Initial encounter
- Receive customer request
- Analyze and understand the current infrastructure and it’s strong/weak points
- ... More
- Build the infrastructure brief and estimate the costs
- Create and agree upon change plan
-
Create and automate the infrastructure
- Based on the presented offer, the best tools to create, automate and maintain the infrastructure are selected
- ... More
- The implementation will be done based on a thorough analysis of the client’s incoming/outgoing traffic and his budget.
- The level of security implemented will meet industry standards and will be done using the latest technologies.
-
Test the new infrastructure
- All planned changes are first applied in a test environment and integration testing will be done with all other resources.
- ... More
- This ensures that the transition will be as smooth as possible for all customer applications.
-
Apply Changes
- After client sign-off, the new infrastructure will be installed and configured along with all its basic needs, such as monitoring and alerting.
- ... More
- Documentation is vital; therefore, a complete handbook will be provided and an actual Change Management process will be put in place in order to make sure that all the users of the new infrastructure are able to use it at optimum levels.
-
Maintenance
- Based on the client needs, a maintenance plan will be put in place which will make sure that all incidents will be tackled with before the business notices it.
