    Study Notes

    Efficient Management with NCI

    • NCI enables organizations to deploy and manage data and applications across data center, edge, and cloud environments efficiently.
    • Reduces complexity and cost associated with traditional IT infrastructure, allowing IT to allocate resources to user workload management.

    HCI Overview

    • Founded in 2009, Nutanix is a leader in hyperconverged infrastructure (HCI), simplifying IT and reducing costs.
    • Nutanix brought web-scale engineering, used by major tech companies, to the broader market, promoting distributed systems on commodity servers.

    Limitations of Legacy Infrastructure

    • Traditional infrastructure with separate storage and servers hinders enterprise applications' demands, adding complexity to management and deployment.
    • Siloed systems require long-term IT planning (3-5 years), often resulting in guesswork and potentially inaccurate forecasts.
    • Vendor lock-in and escalating licensing costs complicate budgeting for enterprise IT teams.

    Data Availability and Resiliency

    • Advanced distributed consistency algorithms protect data against failures, sustaining data availability.
    • AOS Storage offers features like granular automatic self-healing and tunable redundancy to maintain operational integrity.

    Data Protection Features

    • Metadata-based local snapshots provide instant data recovery, meeting various Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO).
    • AOS Storage includes local snapshots and self-service restores for minor incidents, along with Async, NearSync, and Sync replication for major outages.

    Performance Enhancements

    • AOS Storage supports fast, low-latency storage (e.g., SSDs, NVMe) for better performance and scalability.
    • Compute-only (CO) nodes enhance computing capacity without needing additional storage, ideal for workloads like Virtual Desktop Infrastructure (VDI).
    • Storage-only (SO) nodes allow independent scaling of storage capacity without requiring extra hypervisor licenses.

    Storage Management

    • Storage policies enable easy creation and management of attributes like replication factor, encryption, and QoS for virtual machines and volume groups.
    • AOS Storage incorporates technologies such as compression, deduplication, and erasure coding for optimal data efficiency.

    Prism Management Capabilities

    • Prism Infrastructure facilitates management of cluster components, including VMs, storage, and network elements across registered clusters.
    • Admin Center allows inventory management, software updates, and deployment of Nutanix applications for operational efficiency.

    Security and Compliance

    • Flow Network Security provides robust application security through microsegmentation and centralized policy management to enhance network visibility and compliance.
    • Microsegmentation limits inter-application communication to reduce potential malware spread and enhance security at the VM or application level.

    Multi-Cloud Security

    • Security Central extends Flow Network Security, focusing on microsegmentation and continuous security compliance monitoring across multiple cloud environments, assessing risk posture and planning.
