Mastering VMware NSX for vSphere 2020

VMware NSX، با ارائه یک مدل عملیاتی کاملا جدید برای شبکه‌بندی، این چالش‌های دیتاسنترها را حل می‌نماید. این مدل، از موانع شبکه‌های فیزیکیِ فعلی عبور نموده و این امکان را برای اپراتورهای دیتا‌سنتر فراهم می‌کند تا به قابلیت چابکی و مقرون به صرفه بودن بیشتری دست یابند. VMware NSX، یک مجموعه کامل از سرویس‌ها و فاکتورهای منطقی و ساده‌شده‌ی شبکه‌بندی را ارائه می‌نماید که شامل روترها، فایروال‌ها، LoadBalancerها، VPN، QoS، مانیتورینگ، امنیت و سوئیچ‌های منطقی می‌شود. این سرویس‌ها در شبکه‌های مجازی و از طریق هر یک از پلتفرم‌های مدیریت Cloud که از NSX APIها استفاده می‌کنند، آماده‌سازی شده و در هر نوع توپولوژی به صورت مجزا و Multi-Tenancy ارائه می‌گردند. همچنین شبکه‌ های مجازی را می‌توان بدون قطعی در هر یک از شبکه‌های موجود و Hypervisor ها به کار گرفت.

A clear, comprehensive guide to VMwares latest virtualization solution

Mastering VMware NSX for vSphere is the ultimate guide to VMware’s network security virtualization platform. Written by a rock star in the VMware community, this book offers invaluable guidance and crucial reference for every facet of NSX, with clear explanations that go far beyond the public documentation. Coverage includes NSX architecture, controllers, and edges; preparation and deployment; logical switches; VLANS and VXLANS; logical routers; virtualization; edge network services; firewall security; and much more to help you take full advantage of the platform’s many features.

More and more organizations are recognizing both the need for stronger network security and the powerful solution that is NSX; usage has doubled in the past year alone, and that trend is projected to grow—and these organizations need qualified professionals who know how to work effectively with the NSX platform. This book covers everything you need to know to exploit the platform’s full functionality so you can:

  • Step up security at the application level
  • Automate security and networking services
  • Streamline infrastructure for better continuity
  • Improve compliance by isolating systems that handle sensitive data

VMware’s NSX provides advanced security tools at a lower cost than traditional networking. As server virtualization has already become a de facto standard in many circles, network virtualization will follow quickly—and NSX positions VMware in the lead the way vSphere won the servers. NSX allows you to boost security at a granular level, streamline compliance, and build a more robust defense against the sort of problems that make headlines. Mastering VMware NSX for vSphere helps you get up to speed quickly and put this powerful platform to work for your organization.
