A.2. Let us understand the impact of DevOps through some examples:
Netflix and Facebook are investing in DevOps to automate and accelerate application deployment and this has helped them grow their business tremendously. Facebook’s continuous deployment and code ownership models have helped them scale up and ensure high quality experience at the same time. Hundreds of lines of code are implemented without affecting the quality, stability, and security of the product.
Netflix is a streaming and on-demand video company which also follows similar practices and has fully automated processes and systems.
Facebook today, has 2 billion users while Netflix streams online content to more than 100 millions users worldwide. This is how DevOps has helped organizations ensure higher success rates for releases, reduce the lead time between bug fixes, streamline and continuously deliver through automation, and reduce their manpower costs.
