What is Cloud-Native DevOps

Nishant Sharma | 27 Feb 2020 | Newsletter, Cloud Native Application

Technology evolution is a continuum wherein separate developments come together at different points in time to create unprecedented impact. Sometimes a technology maybe around for a long time and become popular only with the arrival of an enabling technology. Cloud-native DevOps falls under the second category—some of its key technology such as Containers, Dockers, Kubernetes have been around for a relatively long time but have seen huge adoption with the maturity of Cloud.

Setting the Context: The Arrival of DevOps
Implementing Cloud-Native DevOps

CULTURAL CHANGE: The process must start with employee reorientation from working in silos to working together and teams must acquire horizonal understanding of the environment including roles, tools, and goals. For example, a software developer gains knowledge how operations work and know the full stack from coding to hosting while a system administrator learns coding, scripting, integration and testing.
FEEDBACK LOOP: All stakeholders including end users/customers must be onboard and provide continuous feedback for improvement. User feedback is captured in automated tools and developers make changes to optimize user experience.

Characteristics of Cloud-Native DevOps

Cloud-native DevOps enable high-velocity software release at scale using following technologies:
Microservices: Services are built using loosely-coupled architectures making each service independent, autonomous and easily scalable. Elastic infrastructure and microservices architecture help applications easily scale and remain highly performant.
Containers: Containers enable developers to ship code without worrying about the underlying infrastructure making it easier to deploy and update applications; and isolate in case of failure. Unlike virtual machines, containers can be provisioned faster and scale out rapidly.
Infrastructure-as-code: Configuration management tools such as Cloud Formation and Ansible enable IT to provision servers and configuring software, middleware and infrastructure. Automating configuration management provides consistent environment and makes it easy for developers to deploy software.
Container orchestration with Kubernetes: Kubernetes solves many of the pain points of deploying and managing containers and microservices. Managed container orchestration services such as AWS ECS and EKS are frequently used by Cloud native DevOps practitioners.
CICD: CICD enables DevOps teams to frequently validate and deliver applications through automation and continuous movement of code throughout the development lifecycle to make multiple releases per day. CICD equips rollback capabilities. Common CI/CD tools include Jenkins and Bamboo.
Continuous Monitoring: Sophisticated monitoring tools are used to track and monitor the environment, ensure compliance and high application performance. In case of non-compliance alerts are sent and auto remedial measures taken. Logs are stored for quick resolution.
Serverless: Function-as-a-service such as AWS Lambda enable DevOps engineers to execute operational functions easily by coding logic in stateless containers which are triggered by events without having to maintain server updates, fault-tolerance, scalability and monitoring.
Cloud native DevOps is a dynamic practice as tools emerge enabling engineers to develop and ship quality code faster. It is a unique journey for each organization as processes are constantly optimized to align with business goals helping to truly exploit the transformational capabilities of Cloud.
