Originally designed by Google, the project is now maintained by the Cloud Native Computing Foundation (CNCF) since 2016.Kubernetes manages containerized workloads and services, that facilitate both declarative configuration and automation.Kubernetes automates operational tasks of container management and includes built-in commands for deploying applications, rolling out changes to your applications, scaling your applications up and down to fit changing needs, monitoring your applications, and more—making it easier to manage applications.Kubernetes networking work?Kubernetes networking works by creating pods and services. A pod is a group of one or more containers that are deployed together and share a network namespace and IP address. Containers within a pod can communicate with each other using a localhost. Services are used to expose one or more pods to the outside world. Key Features of Kubernetes (in Bullet Points):Container Orchestration: Kubernetes manages containers (e.g., Docker) and ensures they are running in desired states.Cluster Management: It organizes containers into clusters of nodes, abstracting the underlying infrastructure.Automated Scaling: Kubernetes can automatically scale applications up or down based on resource usage or defined policies.Service Discovery: It provides DNS-based service discovery and load balancing for containers within the cluster.Rolling Updates: Supports zero-downtime updates by gradually replacing old containers with new ones.Self-Healing: Monitors application health and automatically replaces or reschedules containers in case of failures.Declarative Configuration: Describes desired application state in YAML or JSON, allowing easy versioning and reproducibility.Resource Management: Allocates CPU, memory, and other resources to containers, preventing resource contention.Storage Orchestration: Manages storage volumes and attaches them to containers as needed.Networking: Kubernetes provides networking solutions to connect containers within and outside the cluster.Secrets and ConfigMaps: Securely manage sensitive data and configuration settings for applications.Multi-Cloud and Hybrid: Can run on various cloud providers and on-premises infrastructure, promoting portability.Extensibility: Kubernetes has a rich ecosystem of plugins (e.g., custom resource definitions) and extensions.Role-Based Access Control (RBAC): Granular control over who can access and modify resources within the cluster.Observability: Supports monitoring and logging tools for gaining insights into application performance.Community and Ecosystem: Kubernetes has a large and active community, contributing to its continuous improvement.Compatibility: Supports various container runtimes, including Docker, containerd, and CRI-O.Horizontal and Vertical Scaling: Can scale both the number of instances (horizontal) and the resources allocated to a container (vertical).Self-Service Portals: Allows developers to define and manage their applications without direct interaction with operations teams.Customization: Highly configurable through its extensive API and configuration options.Hyperledger Fabric Overview:Hyperledger Fabric is an open-source enterprise blockchain platform developed under the Linux Foundation's Hyperledger project. It's designed to provide a framework for building permissioned blockchain networks for businesses and consortiums.Key Features of Hyperledger Fabric Permissioned Blockchain: Hyperledger Fabric allows organizations to control access to the network, making it suitable for business consortia and enterprise use.Modular Architecture: Its modular design enables plug-and-play components, including consensus algorithms, identity management, and storage solutions.Smart Contracts (Chaincode): Fabric supports smart contracts, known as chaincode, which are written in familiar languages like Go, JavaScript, and Java.Private Data: Allows for confidential transactions and data sharing between authorized parties while maintaining privacy.Pluggable Consensus: Supports various consensus algorithms, including Practical Byzantine Fault Tolerance (PBFT), Kafka, and Raft.Channel Support: Fabric enables the creation of private channels within the network, where transactions are visible only to specific participants.Permissioned Membership: Network participants are authenticated and authorized, ensuring trust and security.Identity Management: Integrates with various identity solutions, including certificate authorities (CAs) and LDAP, for user and peer authentication.Endorsement Policies: Defines criteria for approving and endorsing transactions, offering fine-grained control over consensus.Scalability: Fabric is designed for scalability, with support for multiple organizations, nodes, and channels.Pluggable Database Support: Supports multiple databases, including LevelDB and CouchDB, for storing ledger data.Rich Querying: Allows for complex queries of blockchain data using Chaincode.Interoperability: Hyperledger Fabric can be integrated with other Hyperledger projects and blockchain platforms.Rich SDKs: Provides SDKs for popular programming languages to facilitate application development.Governance Model: Offers tools for network administrators to manage and govern the blockchain network.Permissioned and Confidential Transactions: Ensures that only authorized parties can access and transact with specific data.Versioning and Upgrades: Supports the ability to upgrade the network and chaincode while maintaining data integrity.Integration with Existing Systems: Can integrate with existing enterprise systems and legacy databases.Auditing and Compliance: Provides tools for auditing and compliance with regulatory requirements.Active Community: Hyperledger Fabric has a thriving community of developers and contributors.Falcon projectAs per NPCI officials, Falcon is an open-source project that combines Hyperledger fabric deployment with Kubernetes.
