Über dieses Buch

This book is for enterprise and solution architects, systems integrators, and anyone managing enterprise-scale, multi-cloud or hybrid IT landscapes. The book examines usage of Azure Arc for governance and systems management with security as an overarching theme. It is not an implementation manual but provides high-level guidance on best practices and links to detailed guidance. It offers insight into the types of problems that Azure Arc can solve, and will help you determine whether it is the right choice for your organization.

Modern enterprise computing is an astonishing luxury land filled with never-before-seen hosting options on commercial clouds as well as advancements in the areas of private cloud and edge computing. The challenge with this plethora of choices is to manage and coordinate large IT estates which may bridge multiple public clouds and private datacenters. Visibility of operations to achieve security, cost control, and efficiency is often difficult to achieve. Data management is another area which is particularly fraught with complexity and risk.

Industry leaders have made serious investments in the design of control plane products to address these gaps with varying approaches and degrees of success. Azure Arc is designed to provide a consolidated view of assets such as databases and Kubernetes installations across major cloud providers, edge locations, and customer-owned datacenters. It facilitates deployment of new infrastructure, patching and upgrades, monitoring, policy, and security controls for assets living on-premises or in competitor clouds as if they were native to Azure. While competitive products exist, at this writing none have the flexibility and reach of Arc to effectively manage very large hybrid estates.

Readers will appreciate the author’s approach of walking through typical enterprise computing scenarios while listing industry- or scenario-specific challenges that are difficult to overcome, and then reinforcing understanding by restating the challenges while explaining how Azure Arc can be utilized to remediate them.

What You Will Learn

Discover what Azure Arc is, the types of problems it is intended to solve, and how to map your requirements to its capabilitiesStreamline and secure large Arc-enabled Kubernetes deployments via modern GitOps practicesUse Azure Arc to consolidate management across a broad range of hybrid and multi-cloud ecosystems through policy-driven governanceApply monitoring and automation to defend systems against security threats that are beyond the ability of manual administration to deflectUncover practical guidance that is written in a way that makes basic precepts approachable to non-technical stakeholders and then branches out into areas that will offer advanced readers new insights and consolidate a broad topic into a usable direction

Chapter 1. The Challenges of Enterprise-Scale Hybrid and Multi-cloud Architectures
Abstract
The innovation of technology solutions available to enterprise-scale organizations continues to grow exponentially and at an astonishing pace. While adopting new technology is a vital strategy for profitability and growth, it also creates significant hurdles with transitions between product stacks, integration with existing solutions, and the critical need to observe and control the entire information technology [IT] estate of an organization. This book aims to investigate what the author believes to be the most comprehensive control plane for IT systems governance available on the market today, Azure Arc. It will cover the product’s capabilities across management of database systems, Kubernetes, governance and policy, security, and its contributions to industry best practices such as DevOps. While focusing on Arc, some comparisons will be made to other products that have similar objectives. Finally, it will offer some historical context as to how the platforms impacted by Arc developed and what fostered the need for a product like Arc.

Chapter 2. What Is Azure Arc?
Abstract
The unification of IT infrastructure management under a “single pane of glass” has been an end of the rainbow objective since the beginning of enterprise computing. The Jenga tower of interdependent resources that is created as organizations grow can be read like tree rings to examine what led to the current health of IT systems – the thin year when we didn’t have sufficient staff and nothing was documented, the fat year when many new products were purchased but without sufficient time for integration testing, or the steady years when there was a consolidated stack working relatively well followed by the evidence of fire when a major security breach occurred.

Chapter 3. Overview of Benefits of Arc in the Enterprise
Abstract
What is “enterprise” computing? Gartner defines an enterprise as a business with more than a thousand employees or more than 50M in revenue. Such organizations require specialized tools to scale, govern, and monitor large IT landscapes. Today, businesses of all sizes can take advantage of an enterprise computing paradigm simply by consuming SaaS [Software as a Service] or PaaS [Platform as a Service] offerings from major cloud vendors. However, solutions that might be required for a large enterprise could be burdensome to a smaller business to purchase and maintain. If you don’t have acres of database servers, IT assets that may have a wide geographic distribution, edge computing installations, hybrid installations, or vast farms of VMs or containers, then your organization may realize enough benefit from using Azure’s many monitoring tools without the Arc umbrella.

Chapter 4. Securing the Enterprise with Arc
Abstract
The impact of enterprise security failures is increasing as tolerance for missteps decreases. Countless breaches of consumer data have often been met with token fines and pats on the head to injured users in the form of a year or two of credit monitoring, a tepid remedy that in no way resolves the situation for those whose identity was actually misused. As failures begin to impact national security and the internal workings of large corporations though, the reaction is becoming more proportionate. The now famous SolarWinds failure to protect corporate and government consumers of its security tools is resulting in lawsuits. A November 2021 suit filed against SolarWinds board by two pension funds accuses SolarWinds of failures that are patently ridiculous for a company purporting to provide IT security, such as using “solarwinds123” as a network password.

Chapter 5. Enterprise DBS Management and Arc
Abstract
Before discussing the scenario of a SQL Server migration, it will be helpful to understand the data services Arc provides, both in how they underpin activities like migration and other benefits that are gained with Arc as the control plane for SQL Server installations.

Chapter 6. Managing Kubernetes Workloads in Hybrid or Multi-cloud Data Centers
Abstract
Kubernetes is foundational to Arc’s capabilities. For instance, extending Azure PaaS services such as Key Vault, App Service, Arc-enabled data services, and more to edge or on-premise locations relies on the Kubernetes runtime. Once your clusters are Arc enabled and running stably, wherever they are located, all of these services can be pushed to the cluster where it is most advantageous to have them running – you are no longer constrained to run your infra on Microsoft’s cloud to take advantage of Azure PaaS.

Chapter 7. Policy and Governance of Hybrid and Multi-cloud Infrastructure
Abstract
One way to think about policy is as an enforced objective. To be useful, a technology estate must be shaped to suit its purpose. It is constantly subjected to disruptive forces and requires not only that the initial design targets be met but constant tuning to ensure it continually aligns to its desired state.

Chapter 8. Monitoring and Process Automation via the Arc Control Plane
Abstract
We touched on process automation in the Kubernetes chapter when discussing GitOps. As we take a closer look at what can be achieved, it will become apparent that the surface area to which it can be applied is much broader than operations and that Azure Arc has unique features that can assist in our journey to actively administer large IT estates that are governed, implemented, and managed by automation. Process automation is a big topic that deserves its own book, so this chapter will focus on how the reach of the Arc control plane allows you to extend automation across the IT estate and further is instrumental in creating the feedback loop that nourishes your automated processes.

Chapter 9. Automation in the Era of ML and AI
Abstract
No discussion of process automation can overlook the explosion of artificial intelligence [AI] into the public consciousness, now that what just a few years ago might have been referred to as machine learning [ML] input put to intelligent use for Robotic Process Automation [RPA] has come to be thought of as AI. To apply the term “artificial” to what is being produced is only truthful in the sense that the calculations and deductive reasoning are not being performed by a biological intelligence. The output itself is not artificial in the sense of being fake, any more than a calculator producing an answer to an equation would make the answer invalid. We are in the industrial age for brain laborers, and the opportunities that presents are exciting in terms of velocity for business growth and solutions for previously unresolved technical roadblocks for the same.

Chapter 10. Azure Arc – History and Horizons
Abstract
From bi-quinary wooden abacus to the vacuum tube electronics of the Colossus code-breaking machine used in WWII, from mainframe to personal computers to the advent of quantum computing, from programming that had to account for and reuse infinitesimally small pieces of the memory register to RAM that can carry massive loads of computational data, and from IBM’s 20-foot-long 236GB mass storage system half a century ago to the prospect of storing a quarter-million terabytes in one gram of DNA, changes in the capabilities and scale of the technologies invented within the last century have exceeded the ability of their creators to fully manage them well before AI was factored in, and that divergence is part of what makes AI/ML fully necessary. When the breathtaking reality of the reorganization by technological advancement of not only human lives but our very environment sets in, then tools like Arc begin to seem not utilitarian but heroic as we use them to meet the challenges we have laid out for ourselves.
