The Big Book Of Microservices

This is because, with microservices, development teams do not have to rewrite and deploy the whole application when new features are added. In addition, it takes less time and is much easier to conduct continuous maintenance.

The Big Book Of Microservices

Microservices, a form of software architecture approach, allows companies to deliver services and products faster, and with scalability and flexibility. The guiding principle of microservices is to build an application by breaking down its business components into smaller services, which can be deployed and operated independently from each other. This sets it apart from the more traditional, monolithic architecture wherein all components are bundled together. Companies that successfully adopt the appropriate microservice patterns for their application can greatly increase the time it takes to convert their ideas into customer value, which sustains long-term customer relationships and generates revenue. This is because, with microservices, development teams do not have to rewrite and deploy the whole application when new features are added. In addition, it takes less time and is much easier to conduct continuous maintenance. In this Microservice Technologies book, you will discover a great detail on all of the Microservice Architecture patterns including: - Monolithic Architecture - Microservice Architecture - Service Discovery - Gateway / Proxy API - Orchestrated API - Service Registration - CQRS and Event Sourcing - Bulk Heads - Circuit Breaker - Message Broker Besides, you'll also learn about what technologies you need to use and understand for successful Microservices: - Virtualization - Containers (Docker and Rocket) - Databases - Security (JSON Web Tokens) - Logging - Exceptions - Caching - Timeouts - Scalability (CAP, Cube) - Platform as a Service (PaaS) - Cloud architecture - Technology agnostic Whether you are a software architect/developer or systems professional looking to move on from older approaches or a manager trying to maximize the business value of these technologies, this book is a must-read.

iRODS Primer 2

In summary, the first three components of a Rule consist of an action name, a testable condition, and a chained workflow consisting of actions and microservices. e order of the Rule in the Rule Base determines its priority.

iRODS Primer 2

Policy-based data management enables the creation of community-specific collections. Every collection is created for a purpose. The purpose defines the set of properties that will be associated with the collection. The properties are enforced by management policies that control the execution of procedures that are applied whenever data are ingested or accessed. The procedures generate state information that defines the outcome of enforcing the management policy. The state information can be queried to validate assessment criteria and verify that the required collection properties have been conserved. The integrated Rule-Oriented Data System implements the data management framework required to support policy-based data management. Policies are turned into computer actionable Rules. Procedures are composed from a microservice-oriented architecture. The result is a highly extensible and tunable system that can enforce management policies, automate administrative tasks, and periodically validate assessment criteria. iRODS 4.0+ represents a major effort to analyze, harden, and package iRODS for sustainability, modularization, security, and testability. This has led to a fairly significant refactorization of much of the underlying codebase. iRODS has been modularized whereby existing iRODS 3.x functionality has been replaced and provided by small, interoperable plugins. The core is designed to be as immutable as possible and serve as a bus for handling the internal logic of the business of iRODS. Seven major interfaces have been exposed by the core and allow extensibility and separation of functionality into plugins.
