Serverless as a Game Changer: Addison-Wesley Signature Serie
Autor Joseph Emisonen Limba Engleză Paperback – 30 oct 2023
Structura progresivă: de la concept la implementare, ne ghidează prin ceea ce autorul numește „mentalitatea serverless”, un model strategic de a privi tehnologia nu doar ca infrastructură, ci ca un motor de valoare pentru business. Observăm că Serverless as a Game Changer nu se limitează la aspectele tehnice ale platformelor de calcul, precum AWS Lambda, ci propune o reevaluare a întregii stive tehnologice. Joseph Emison, din postura de director tehnologic experimentat, argumentează convingător de ce codul este adesea o pasivitate, în timp ce experiența oferită utilizatorului reprezintă adevăratul activ al unei companii.
Suntem de părere că rigoarea analizei costurilor — de la cele directe la cele de oportunitate — oferă cititorului instrumentele necesare pentru a lua decizii informate de tip „build-or-buy”. Complementar lui Serverless Beyond the Buzzword, care se concentrează pe definirea termenilor și a beneficiilor generale, volumul de față acoperă zona aplicată a selecției furnizorilor de servicii gestionate (COTS) și optimizarea proceselor de livrare software pentru întreprinderi mari. Găsim în această carte un director detaliat de servicii care pot simplifica radical arhitecturile moderne, multe dintre acestea fiind adesea ignorate de arhitecții software tradiționali.
Organizarea cărții reflectă o progresie logică: prima parte stabilește bazele economice și strategice, capitolul dedicat costurilor reale fiind esențial pentru orice lider tehnic, în timp ce secțiunile ulterioare detaliază criteriile tehnice și implementarea prin studii de caz. Spre deosebire de Distributed Serverless Architectures on AWS, care este focalizat strict pe ecosistemul Amazon, lucrarea lui Emison oferă o perspectivă mai largă, strategică, asupra modului în care serviciile gestionate pot prelua sarcinile care nu aduc valoare adăugată directă, permițând echipelor să inoveze mai rapid.

Descriere scurtă
In this definitive guide, Joseph Emison shows how to leverage serverless for maximum customer value. He reveals why mindset is crucial to modern IT strategy and explains why and how to move toward a truly serverless mindset.
Many organizations are falling short when it comes to leveraging the cloud. Drawing on his experience as a pioneering CTO across multiple industries, Emison shows why and how you can gain immense business value from the cloud. While many serverless adopters focus on converting and building apps on serverless compute platforms like AWS Lambda, Emison offers better ways to think about your tech stack, optimize build-or-buy decisions, choose the right vendor for each commercial off-the-shelf (COTS) or open-source solution, and draw on the industry's best managed services.
To help you develop a serverless mindset, Emison includes a case study demonstrating a real-world enterprise transition to serverless. The author also provides an exclusive directory of current managed services with focused descriptions and concise explanations of each service and its role in modern application architecture. Many of these services are unfamiliar to enterprise architects, but they are enterprise tested and can radically simplify any serverless transition.
- Evolve your tech stack and mindset to gain the full benefits of the cloud
- Deliver software faster, better, and at lower cost with serverless
- Use serverless architectures and managed services to offload tasks that dont add value
- Follow a real-world case study taking you from where you are to where you want to be
- Explore an exclusive managed services directory to find resources to streamline your serverless transition
