This presentation is devoted to current trends that affect DevOps activities. It also deals with Cloud Flex Framework, a Kubernetes-based framework, which provides a set of flexible and comprehensive operation principles to cover all stages of a modern application life cycle. This presentation was held by Denys Vasyliev (Lead Software Engineer, Consultant, GlobalLogic) at GlobalLogic Kyiv DevOps Career Day on June 9, 2018.

3. Cloud Native Infrastructure - is infrastructure that is hidden behind
useful abstractions, controlled by APIs, managed by software, and has
the purpose of running applications. Running infrastructure with these
traits gives rise to a new pattern for managing that infrastructure in a
scalable, efficient way.
Cloud Agnostic - A repeatable deployment that will work no matter
where you deploy it: on-premises, in OpenStack, in AWS, Google and
Alibaba Cloud or perhaps even in Azure.
Microservices Application - also known as the microservice
architecture pattern - is an architectural style that structures an
application as a collection of loosely coupled services, which implement
business capabilities. The microservice architecture enables the
continuous delivery/deployment of large, complex applications.
Best Practices - is a practices have been authored by the cloud native
community. Features a comprehensive list of technical approaches,
covering topics such as architecture, methods, tools, security and
monitoring.

Service Mesh
● Traffic Management. Control the flow of traffic and
API calls between services
● Service Identity and Security. Provide the
ability to protect service traffic as it flows
● Policy Enforcement. Apply organizational policy to
the interaction between services
● Telemetry. Gain understanding of the dependencies
between services and the nature and flow of traffic
between them
