Solutions Architect's Handbook

By: Saurabh Shrivastava, Neelanjali Srivastav

Overview of this book

Becoming a solutions architect gives you the flexibility to work with cutting-edge technologies and define product strategies. This handbook takes you through the essential concepts, design principles and patterns, architectural considerations, and all the latest technology that you need to know to become a successful solutions architect. This book starts with a quick introduction to the fundamentals of solution architecture design principles and attributes that will assist you in understanding how solution architecture benefits software projects across enterprises. You'll learn what a cloud migration and application modernization framework looks like, and will use microservices, event-driven, cache-based, and serverless patterns to design robust architectures. You'll then explore the main pillars of architecture design, including performance, scalability, cost optimization, security, operational excellence, and DevOps. Additionally, you'll also learn advanced concepts relating to big data, machine learning, and the Internet of Things (IoT). Finally, you'll get to grips with the documentation of architecture design and the soft skills that are necessary to become a better solutions architect. By the end of this book, you'll have learned techniques to create an efficient architecture design that meets your business requirements.

Kerberos is an authentication protocol that allows two systems to identify each other in a secure way and helps to implement SSO. It works in the client-server model and uses a ticket system for user identity. Kerberos has the Key Distribution Center (KDC), which facilitates authentication between two systems. The KDC consists of two logical parts—the Authentication Server (AS) and the Ticket-Granting Server (TGS).

Kerberos stores and maintains the secret keys of each client and server in the datastore. It establishes a secure session between two systems during their communication and identifies them with the stored secret key. The following diagram illustrates the architecture of Kerberos authentication:

Kerberos authentication

As shown in the preceding diagram, when you want to access a service, the following steps are involved:

  1. The client sends an access ticket request to the AS as a plaintext request. This request contains the client ID, TGS ID, IP address, and authentication...
