Taschenbuch. Zustand: Neu. Neuware - The Blueprint for Scaling Enterprise Generative AI Without Breaking Your Compute, Your Storage, or Your Budget.Move your intelligent systems out of development sandboxes and into a resilient, production-grade physical reality.You have designed autonomous workflows. You have mapped out collaborative multi-agent teams. You have established strict corporate governance frameworks. But a critical question remains: Is your infrastructure actually built to handle them Too many enterprise AI initiatives fail not because of flawed software logic, but because they collapse under the heavy weight of physical production constraints. When cluster power density bottlenecks your compute, unoptimized inference engines drive latency through the roof, or runaway cloud bills bankrupt your budget, even the most brilliant AI application becomes completely useless.In Enterprise AI Infrastructure, the definitive final volume of The Enterprise AI Architect's Handbook series, you will discover exactly how to build the physical and technical backbone required to sustain high-performance, intelligent systems at scale. Skipping the basic introductory definitions, this book plunges directly into senior-level engineering realities, giving you the concrete architectural patterns and trade-off matrices needed to deploy modern LLMs with absolute confidence.Inside this comprehensive architecture guide, you will master: - The Compute Backbone: Navigating the hardware landscape (Nvidia Hopper/Blackwell, AMD Instinct, and custom ASICs), liquid cooling transitions, and high-throughput networking topologies like InfiniBand vs. RoCEv2.- Distributed Training Topologies: Optimizing fine-tuning footprints using Data, Model, Pipeline, and Tensor Parallelism alongside ZeRO stages 1-3 memory management.- The Data Substrate: Architecting real-time, terabyte-scale ingestion pipelines, object storage tiers, and high-density vector database indexing algorithms (HNSW vs. IVF-PQ).- Runtime Engineering: Maximizing inference throughput using continuous batching, PagedAttention, quantization frameworks, and advanced multi-hop enterprise RAG architectures.- Agentic Infrastructure Hosting: Building the physical state stores, semantic routers, and asynchronous message brokers (Kafka/Pulsar) required to support collaborative agent swarms.- Enterprise FinOps & Green AI: Running a rigorous Total Cost of Ownership (TCO) analysis to compare cloud vs. on-premises architectures while keeping token costs and carbon footprints strictly optimized.Whether you are an Enterprise AI Architect designing end-to-end hardware blueprints, an MLOps Engineer scaling runtime container clusters, a Data Principal managing high-dimensional data flows, or a tech executive managing a multi-million dollar AI budget, this book is your ultimate operations manual.…

Taschenbuch. Zustand: Neu. Neuware - The 'Chatbot' Era is Over. The Era of the Autonomous Enterprise Has Arrived.Stop building toys. Start architecting systems.The industry is saturated with guides on how to 'talk' to AI, but the modern enterprise doesn't need better prompts, it needs better orchestration. As companies scramble to move beyond simple chat interfaces, a massive technical gap has emerged: the ability to build reliable, self-correcting, and scalable AI pipelines that actually do the work.In Practical AI Workflow Orchestration, Leonard J. Horta pulls back the curtain on Flow Engineering, the art of designing AI systems that think, reason, and execute with the precision of high-performance software. This isn't a book about what AI might do; it's a manual for what AI must do to survive in a production environment.What You Will Master: - From Chains to Agents: Move beyond basic sequential logic to build complex, agentic swarms that handle high-stakes corporate tasks.- Reasoning Frameworks: Implement ReAct, Tree-of-Thought, and self-correction loops to eliminate hallucinations and ensure system reliability.- The Architecture of Autonomy: Design 'Human-in-the-Loop' (HITL) checkpoints that maintain safety without sacrificing speed.- Production Hardening: Secure your pipelines against injection attacks and optimize for latency, cost, and observability.- Vendor-Agnostic Blueprints: Build robust systems that aren't tied to a single provider, ensuring your architecture remains future-proof.Why This Book While others are stuck in the 'experimental' phase, you will be deploying. Whether you are a Systems Architect, a CTO, or a Senior Developer, this book provides the engineering rigor required to transform probabilistic AI into a deterministic business asset.Practical AI Workflow Orchestration is the first volume in the Enterprise AI Architect's Handbook series. It is your definitive guide to bridging the gap between cutting-edge LLM potential and the rigid demands of the modern enterprise.Don't just use AI. Orchestrate it.…

Taschenbuch. Zustand: Neu. Neuware - What if your automation could interpret messy requests, choose the right tools, recover from failures, and still behave like production software-bounded, auditable, and safe Practical AI Automation is a hands-on guide to building agentic business automation systems where probabilistic reasoning is contained inside deterministic engineering controls. Instead of treating a single model response like a function call, this book shows how to design governed execution loops: typed tool calls, runtime policy enforcement, persistent state, and termination rules you can test, monitor, and explain.Inside, you'll learn how to: - Build a production agent architecture using a typed state machine, budgets, and replay protection- Expose enterprise capabilities through a schema-validated tool protocol boundary with structured errors, timeouts, and rate limits- Engineer memory and retrieval as governed subsystems that refuse to act without evidence- Implement human-in-the-loop approvals with deterministic pre-execution diffs and resumable interrupts- Defend against prompt injection, data leakage, and unauthorized actions with sanitization, scopes, and audit trails- Evaluate agent systems using trace-based metrics and regression gates that catch prompt/topology drift before release- Deploy and scale with a microservice split (API, workers, tools, state/cache, queue) that enforces backpressure and predictable SLAsWritten for engineers, technical operators, and product teams, this book provides practical blueprints you can adapt to sales/support workflows, financial operations, and internal tooling, without relying on 'trust the model' as your safety plan. The result is agentic automation that can ship: constrained where it must be, flexible where it can be, and accountable everywhere.…

Taschenbuch. Zustand: Neu. Neuware - Are your UI tests 'mostly green' but still fail at random Do you have a handful of scripts, but no framework you can trust in CI/CD Are you stuck copy-pasting tests, fighting flaky waits, and rebuilding suites every time the UI changes Do you know you can do the work, yet interviews and job descriptions still filter you out The Self-Taught Test Automation Engineer is a practical engineering roadmap for turning testing effort into a reliable, scalable quality system. This isn't a tool tour or a collection of disconnected tips. It teaches the engineering decisions behind automation that survives real-world conditions: changing UI, asynchronous apps, parallel execution, environment drift, unstable test data, and the operational demands of pipeline gating.Inside, you'll learn how to design automation like a product: - Select the right work with ROI and risk-based strategy, so you automate what matters and avoid expensive low-signal coverage.- Write maintainable test code using clean OOP boundaries and patterns that prevent 'framework rot.'- Build Page Object and component architectures that keep UI change localized and tests readable.- Eliminate flakiness at the source with dynamic waits, state synchronization, and disciplined resilience (without masking real defects).- Scale coverage safely with data-driven design, scenario models, factories, and environment-aware configuration without leaking secrets.- Move fast with service-layer automation for contract and business-rule validation that's deterministic and deeply diagnostic.- Run suites in parallel and distributed infrastructure without data collisions or shared-state failures.- Integrate into CI/CD with quality gates and observability so failures come with evidence, not guesswork.- Keep suites healthy long-term using suite health metrics, quarantine/pruning policies, and planned dependency upgrades.- Translate skill into career outcomes with a portfolio structure, resume framing, interview readiness, and a first-90-days impact plan.Each chapter includes deliverables you can apply immediately, templates, checklists, scorecards, architecture blueprints, and audit protocols, so you can implement the approach in your own repo and environment.If you want automation that runs unattended, fails with clear evidence, scales with your product, and earns trust across a team, this book gives you the system to build it.…
