Fundamentals of Cloud Native Architecture
📄️ 2.3 Autoscaling Techniques
Autoscaling is a critical feature in cloud-native environments that allows applications to automatically adjust their resources based on demand. By dynamically scaling applications, autoscaling ensures optimal performance and cost efficiency, without requiring manual intervention. This is particularly important in cloud-native architectures where workloads can fluctuate, and resources must be managed efficiently.
📄️ 2.4 Serverless Computing
Serverless computing is a cloud-native model that abstracts infrastructure management, allowing developers to focus solely on writing code without worrying about provisioning or managing servers. In a serverless environment, the cloud provider dynamically allocates resources as needed, scaling them automatically based on demand. Serverless computing is event-driven, meaning functions are executed in response to specific triggers, and users are only charged for the compute time consumed during execution.
📄️ 2.5 Community, Governance, and Standards
Cloud-native technologies have grown significantly, driven by strong community collaboration, open governance, and adherence to widely accepted standards. This approach ensures interoperability, transparency, and innovation, enabling organizations to build, run, and manage scalable and resilient applications in modern cloud environments.
📄️ 2.6 Roles and Personas
Cloud-native ecosystems require various roles and personas that contribute to the successful development, deployment, and management of applications and infrastructure. These roles span across development, operations, security, and leadership, ensuring that the cloud-native environment operates efficiently and meets organizational goals.
📄️ 3.7 Open Standards
Open standards play a vital role in cloud-native architecture, enabling interoperability, portability, and flexibility in diverse cloud environments. By adhering to open standards, organizations can avoid vendor lock-in, leverage a broad ecosystem of tools, and ensure seamless integration of cloud-native components across different platforms. In cloud-native environments, open standards cover key areas like containers, networking, storage, and security, making it easier to build and manage scalable, resilient, and portable applications.
