Network Architect's Handbook

By: Alim H. Ali

Overview of this book

Becoming a network architect is challenging—it demands hands-on engineering skills, encompassing hardware installation, configuration, and fabric layout design. Equally crucial, it involves collaboration with internal teams and C-Suite stakeholders, and adeptly managing external entities like vendors and service providers. The Network Architect's Handbook comprehensively covers these vital aspects, guiding you to evolve into an effective network architect within an organization, fostering seamless communication with leadership teams and other stakeholders. Starting with a clear definition of a network architect’s role, this book lays out a roadmap and delves into the attributes and mindset for success. You’ll then explore network architect design, physical infrastructure routing and switching, and network services such as DNS, MLAG, and service insertion. As you progress, you’ll gain insights into the necessary skills and typical daily challenges faced by network architects. And to thoroughly prepare you to advance in your career, this handbook covers certifications and associated training for maintaining relevance in an organization, along with common interview questions for a network architect's position. Armed with essential concepts, techniques, and your newfound skills, you’ll be well-prepared to pursue a career as a network architect.

The need for cloud computing

Cloud computing solves several critical problems in the realm of IT and technology. Let’s consider the following scenario regarding data analytics:

Data-intensive projects, such as a scientific research initiative, where massive amounts of data need to be ingested, analyzed, and stored.

From the perspective of a network architect, what would be required to build a data-centric architecture to support this initiative on-premises? We’ll need the building blocks: network (fabric), compute, storage (DBs, SAN, NAS, etc.), software (OS, virtualization, middleware, patches, etc.), and data applications (processing, analytics, correlations, home-grown). Let’s keep it at this for now and break down each:

  • Networking: To support this from a (physical) network layer perspective, the architecture will need high-speed, non-blocking, low-latency switches and routers with possibly large queuing buffers and hardware-based encryption for...
