What is DevOps?

Culture that bridges the gap between development and operation teams
Combination of cultural philosophies, practices and tools that increases organisations ability to deliver applications and services at high velocity
Evolving and improving products at a faster pace than organisations using traditional software development and infrastructure management process
combines software development (Dev) and IT operations(Ops) participating together in entire service life cycle
Set of practices that automate the process

Shorter Development Cycles & faster innovation = created through joint development and operations efforts
Reduce Implementation failure, reflections and recovery time= DevOps promotes frequent code versions.Therefore, teams can use their time to reduce the number of implementation failures using agile programming principles that require collaboration and standard programming
Better communication & cooperation = culture focuses on performance rather than individual goals

Overcoming Dev vs Ops mentality = they need to ensure to align the goals and priorities of teams
Moving from legacy infrastructure to microservices = step towards continuous improvement that enables development lifecycle to adapt to changing markets and customer needs. However this requires foundations of automation to be able to cope with the workload that microservices bring
Resistance to change from team members, stakeholders etc. This means members must see the benefits in order to the change to be smooth and gradual

Ability to build, test and release software faster
Speed = innovating for customers faster & changing to markets better. E.g. microservices and continuous delivery let teams take ownership of services and then release updated to them quicker
Rapid Delivery = innovating and improving product faster e.g. releasing new features, fixing bugs

DevOps creates microservices architecture where their code can be tested on their own
It used to take too long to release a product.
They were all dependant on each other
Limited collaboration between teams
DevOps took away this dependability & faster release cycles which saves money - benefits profitability
