Application performance management (APM) is an essential solution alleviating some of that complexity. Today, businesses are using APM to connect app performance and the customer experience to business outcomes. APM tracks the behavior of components, such as physical hardware, virtual machines where applications reside, JVM executing the application environment, web containers, associated databases, caches, external web services, and the code running the application itself. APM also provides detailed insight into the end-user experience, helping you understand the quality of service you're providing to your customers. By using the best practices laid out here, you'll become an expert at making the optimal use of AppDynamics APM. You'll prevent damage to your organization's reputation and delight customers with outstanding performance. This guide will help you understand why APM is critical to the success of your business and establish the best practices in APM strategy to reach, maintain, and suggest new service levels.
Across a variety of large, global companies, DevOps teams are adopting containers and microservices, two of many new tools and practices that are offering solid business benefits. Developers use containers and microservices in many tasks, from app delivery to migration of legacy systems to cloud servers. The increased popularity in containers and microservices can be attributed to their impact on agile cloud environments, with benefits that include increased efficiency, greater speed of delivery, and the ability to do more with existing resources. And while the benefits of containers and microservices are causing an increase in usage, there are also some complexities to be aware of. For example, while usage is exploding, many developers are still learning how to use these relatively new tools and practices. This means organizations must maintain data security, system reliability, and other service levels during the learning curve. Read this guide to get an introduction on how to effectively implement and monitor containers and microservices.
Solr (pronounced "solar") is an open source enterprise search platform, written in Java, from the Apache Lucene project. Its major features include full-text search, hit highlighting, faceted search, real-time indexing, dynamic clustering, database integration, NoSQL features and rich document (e.g., Word, PDF) handling. Providing distributed search and index replication, Solr is designed for scalability and fault tolerance. Solr is the second-most popular enterprise search engine after Elasticsearch. Solr is highly reliable, scalable and fault tolerant, providing distributed indexing, replication and load-balanced querying, automated failover and recovery, centralized configuration and more. Solr powers the search and navigation features of many of the world's largest internet sites. In this ebook, we provide a compilation of Apache Solr tutorials that will help you kick-start your own programming projects. We cover a wide range of topics, from basic usage and installation, to query syntax and synonyms search.
Maven is a build automation tool used primarily for Java projects. Maven addresses two aspects of building software: first, it describes how software is built, and second, it describes its dependencies. Contrary to preceding tools like Apache Ant, it uses conventions for the build procedure, and only exceptions need to be written down. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging. Maven dynamically downloads Java libraries and Maven plug-ins from one or more repositories such as the Maven 2 Central Repository, and stores them in a local cache. This local cache of downloaded artifacts can also be updated with artifacts created by local projects. Public repositories can also be updated. In this ebook, we provide several Maven examples that will help you kick-start your own projects.
