What is DevOps?
DevOps is a set of practices that combine software development and IT operations. The objective is to decrease the systems development life cycle without compromising software quality.
The word DevOps is created by combining the words “development” and “operations.” DevOps is considered a cultural shift by combining development and IT operations instead of functioning in siloed teams. DevOps teams can produce high quality code more quickly as they continuously move through the phases of the DevOps lifecycle. Additional benefits include improved collaboration, better security, and the infrastructure and development processes can be managed at scale.
DevOps practices use correct tooling to aid in quicker innovation. Examples of these tools include frequent and incremental updates, microservices architecture, infrastructure automation, and good monitoring and logging.
There are many different ways to automate and improve DevOps metrics. These include:
- Workflow (for example: using support tickets)
- Knowledge (when there is an incident, the service management tool should automatically generate knowledge and documentation)
- Escalation (a problem is referred to the person who can fix it and not necessarily follow a linear escalation path)
Cloud computing has become more important recently as industry is making a shift to cloud-native, microserve-based applications. Now teams can quickly create cloud environments without the hassle of purchasing, configuring, and maintaining physical hardware.
Benefits of DevOps
Continuous integration and continuous delivery allow for more frequent releases
Ability to maintain systems more stable and reliable
Improved collaboration developes through ownership and accountabilty
Innovating more quickly and adapting to change drives increased effeciency
Infrustrucure as code helps operate and manage processes at scale
Policy as code will help maintain security
