Overview of this book

Microsoft Azure has numerous effective solutions that shape the future of any business. However, the major challenge that architects and administrators face are implementing these solutions appropriately. Our book focuses on various implementation scenarios that will help overcome the challenge of implementing Azure’s solutions in a very efficient manner and will also help you to prepare for Microsoft Architect exam. You will not only learn how to secure a newly deployed Azure Active Directory but also get to know how Azure Active Directory Synchronization could be implemented. To maintain an isolated and secure environment so that you can run your virtual machines and applications, you will implement Azure networking services. Also to manage, access, and secure your confidential data, you will implement storage solutions. Toward the end, you will explore tips and tricks to secure your environment. By the end, you will be able to implement Azure solutions such as networking, storage, and cloud effectively.

Preface

Service models


Cloud computing the new trend model for enabling workloads, that use resources from a a normally extreme huge resource pool, that is operated by a cloud service provider. These resources include servers, storage, network resources, applications, services or even functions. These can be rapidly deployed, operated and automated with a low effort and the prices are calculated on a minute base. This cloud model is composed of five essential characteristics, three service models, and four deployment models.

Cloud offers are mainly categorized into the following service models:

  • The most popular IaaS resources in Azure contain virtual machines, virtual networks (internal and external), container services and storage.
  • Infrastructure as a Service (IaaS): Infrastructure as a Service describes a model in which the cloud provider gives the consumer the possibility to create and configure resources from the computing layer upwards. This includes virtual machines, networks, appliances, and many other infrastructure-related resources:
  • Platform as a Service (PaaS): Platform as a Service gives the consumer an environment from the operating system upwards. So, the consumer is not responsible for the underlying IaaS infrastructure. Examples are operating systems, databases, or development frameworks:
    • Microsoft Azure contains many PaaS resources such as SQL databases, Azure app services, or cloud services.
  • Software as a Service (SaaS): Software as a Service is the model with the lowest levels of control and required management. A SaaS application is reachable from multiple clients and consumers, and the owning consumer doesn't have any control over the backend, except for some application related management tasks.
  • Examples of SaaS applications are Office 365, Visual Studio Online, Outlook website, OneDrive, and even the Amazon website itself is a SaaS app with Amazon as its own consumer.

A comparison of service model responsibilities is as follows:
