Dapris an open source, portable, event-driven runtime that makes it easy for developers to build resilient, microservice, stateless and stateful applications that run on the cloud and edge. Dapr enables developers to focus on writing business logic and not solving distributed system challenges, thereby significantly improving their productivity, and reducing development time. Dapr lowers the bar for entry to build modern cloud native applications based on a microservices architecture and with this v1.0 release, Dapr applications can be deployed to self-hosted infrastructure or Kubernetes clusters in production scenarios.
Foreword byMark RussinovichAzure CTO and Technical FellowMicrosoft
With the wave of cloud adoption well underway, there is a major shift happening towards “cloud native” development, often built with microservice-architectures. These microservices are both stateless and stateful, and run on the cloud and edge, embracing the diversity of languages and frameworks available today. This enterprise shift is driven by both the market forces of faster time to market, as well as the scale and efficiencies of building services for the cloud. Even before COVID-19, cloud adoption was accelerating for enterprises and developers were being asked to do even more to deliver on building these distributed system applications, and that has only accelerated since. Developers in enterprises seek to focus on business logic, while leaning on platforms to imbue their applications with scale, resiliency, maintainability, elasticity, and the other attributes of cloud-native architectures, which is why there is also shift towards serverless platforms that hide the underlying infrastructure. Developers should not be expected to become distributed systems experts. This is where Dapr steps in to help you, whether you are building on infrastructure such as Kubernetes, or on a serverless platform.
Dapr is designed as an enterprise, developer-focused, microservices programming model platform with the mantra “any language, any framework, run anywhere”. It makes building distributed applications easy and portable across any infrastructure, from public-cloud, through hierarchical edge, and even down to single node IoT devices. It emerged from both our experiences building services in Azure as well as time spent working with customers building applications on Azure Kubernetes Service and Azure Service Fabric. Over and over, we saw common problems that they had to address. It became clear that there was a need to provide a “library” of common microservice best practices that developers could use, not only in new greenfield applications, but also to aid in the modernization of existing applications. In the containerized, distributed, and networked cloud native world, the sidecar model has emerged as the preferred approach, in the same way DLLs are preferred in the client/server generation. Using Dapr’s sidecar and APIs give you, as a developer, all the power of distributed systems functionality, with the ease of a single HTTP or gRPC local call.
To address the wide range of scenarios that developers face, Dapr provides features such as state management, service to service invocation, pub/sub and integration to external systems with I/O bindings, which are based on the triggers and bindings of Azure Functions. These in turn take advantage of Dapr’s component model which allows you to “swap out”, say different underlying state stores, without having to change any code, making code more portable, more flexible and allowing for experimentation of what best suits your needs. Developers don’t need to learn and incorporate service SDKs into their code, worry about authentication, secret management, retries or conditional code that targets specific deployment environments.
This book shows how Dapr reduces your development time and overall code maintenance by incrementally “Daperizing” the canonical .NET reference application, eShop. For example, in the original eShop implementation, significant amounts of code were written to abstract between Azure Service Bus and RabbitMQ for publishing events between services. All this code can be discarded and simply replaced with Dapr’s pub/sub API and component model which had an even wider range of pub/sub brokers, rather than just two. Dapr’s actor model, when used in the reworked eShop application, shows the ease of building long running, stateful, event driven, workflow applications with all the difficulties of concurrency and multi-threading removed. By the end of this book, you will see the drastic simplification that Dapr brings to your application development, and I firmly believe all developers embarking on a cloud native app building journey should leverage Dapr.
We publicly announced Dapr with the v0.1 release in Oct 2019 and now, a year and half later, I am thrilled to say that Dapr is ready for production usage with the v1.0 release. Getting Dapr to v1.0 has truly been a community effort. It has been amazing to see the open-source community coalesce around Dapr and grow since it was first announced – from 114 contributors in October 2019 to over 700 in early 2021 – a six-fold increase in 16 months! Contributions to the project have gone to every Dapr repo and have ranged from opening issues, commenting on feature proposals, providing samples, and of course contributing code. The parts of the project community members have contributed to the most include the Dapr runtime, docs, CLI, SDKs and the creation of a rich ecosystem of components. Maintaining this openness is critical to Dapr’s future.
Dapr is really just getting started, though, and you should expect to see more Dapr capabilities and more support for Dapr in Azure services. I hope that you will take advantage of Dapr to enable you to focus on your core business logic and accelerate your microservices development. I am are excited to have you join us in the Dapr community on this journey athttps://github.com/dapr/and on Discord https://aka.ms/dapr-discord.
Modern distributed systems are complex. You start with small, loosely coupled, independently deployable services. These services cross process and server boundaries. They then consume different kinds of infrastructure backing services (databases, message brokers, key vaults). Finally, these disparate pieces compose together to form an application.

About Hands-On Linux Administration on Azure, Second Edition
Thanks to its flexibility in delivering scalable cloud solutions, Microsoft Azure is a
suitable platform for managing all your workloads. You can use it to implement Linux
virtual machines and containers, and to create applications in open source languages
with open APIs.
This Linux administration book first takes you through the fundamentals of Linux and
Azure to prepare you for the more advanced Linux features in later chapters. With the
help of real-world examples, you’ll learn how to deploy virtual machines (VMs) in Azure,
expand their capabilities, and manage them efficiently. You will manage containers
and use them to run applications reliably, and in the concluding chapter, you’ll explore
troubleshooting techniques using a variety of open source tools.
By the end of this book, you’ll be proficient in administering Linux on Azure and
leveraging the tools required for deployment.
Whether you are new to distributed systems or have been deploying cloud-native systems for years, containers and Kubernetes can help you achieve new levels of velocity, agility, reliability, and efficiency. This book describes the Kubernetes cluster orchestrator and how its tools and APIs can be used to improve the development, delivery, and maintenance of distributed applications. Though no previous experience with Kubernetes is assumed, to make maximal use of the book you should be comfortable building and deploying server-based applications. Familiarity with concepts like load balancers and network storage will be useful, though not required. Likewise, experience with Linux, Linux containers, and Docker, though not essential, will help you make the most of this book.
Learn Azure in a Month of Lunches breaks down the most important Azure concepts into bite-sized lessons with exercises and labs—along with project files available in GitHub—to reinforce your skills. Learn how to:
Use core Azure infrastructure and platform services—including how to choose which service for which task.
Plan appropriately for availability, scale, and security while considering cost and performance.
Integrate key technologies, including containers and Kubernetes, artificial intelligence and machine learning, and the Internet of Things.
The velocity of change for the Microsoft SQL Server DBA has increased this decade. The span
between the releases of SQL Server 2016 and 2017 was only 16 months, the fastest new release
ever. Gone are the days when DBAs had between three to five years to soak in and adjust to new
features in the engine and surrounding technologies.
This book is written and edited by SQL Server experts with two goals in mind: to deliver a solid
foundational skillset for all of the topics covered in SQL Server configuration and administration,
and also to deliver awareness and functional, practical knowledge for the dramatic number
of new features introduced in SQL Server 2016 and 2017. We haven’t avoided new content—
even content that stretched the boundaries of writing deadlines with late-breaking new releases.
You will be presented with not only the “how” of new features, but also the “why” and the
“when” for their use.

End-to-end Pipelines for Automating Microsoft Azure Deployments
Imagine a fully automated, end-to-end pipeline for your cloud deployments—one that encompasses and automates everything:
• Source code repos.
• The build and release iterations.
• Agile processes supported by continuous integration and continuous deployment (CI/CD)
• Security and governance.
• Business unit chargebacks.
• Support and maintenance.
Azure services and infrastructure-as-code (IaC) make control plane automation very achievable. Many enterprise IT groups dream of creating or unifying their disparate automation processes and supporting a common, enterprise-wide datacenter control plane in the cloud that is integrated with their existing or new DevOps workflows. Their development environments may use Jenkins, Azure DevOps Services (formerly Visual Studio Team Services), Visual Studio Team Foundation Server (TFS), Atlassian, or other services. The challenge is to automate beyond the CI/CD pipeline to the management and policy layers. From a planning and architecture standpoint, it can seem like an overwhelming program of interdependent systems and processes. This guide outlines a planning process that you can use for automated support of your cloud deployments and DevOps workflows beyond the CI/CD pipeline. The Azure platform provides services you can use, or you can choose to work with third-party or open source options. The process is based on real-world examples that we have deployed with enterprise customers on Azure.

Enterprises are increasingly realizing cost savings, solving deployment problems, and improving DevOps and production operations by using containers. Microsoft has been releasing container innovations for Windows and Linux by creating products like Azure Container Service and Azure Service Fabric, and by partnering with industry leaders like Docker, Mesosphere, and Kubernetes. These products deliver container solutions that help companies build and deploy applications at cloud speed and scale, whatever their choice of platform or tools.
Docker is becoming the de facto standard in the container industry, supported by the most significant vendors in the Windows and Linux ecosystems. (Microsoft is one of the main cloud vendors supporting Docker.) In the future, Docker will probably be ubiquitous in any datacenter in the cloud or on-premises.
In addition, the microservices architecture is emerging as an important approach for distributed mission-critical applications. In a microservice-based architecture, the application is built on a collection of services that can be developed, tested, deployed, and versioned independent
