The idea is to design the API in a way that it serves its purpose best and the consumers are enabled to work efficiently.</p>\n<p>There are several advantages to this approach. For example, it can help to avoid reflecting the internal structure of the application or any internal constraints. Furthermore, as one of the most important design aspects is consistency, one can define features such as the behavior of security, URL schemes, and API keys upfront. It also helps speed up parallel implementation. A team that consumes the API can start working directly after the API design because it can easily be mocked.</p>\n<p>There are several tools for modelling an API, but here at AOE we mainly use <a href=\"/techradar/tools/raml.html\">RAML</a> as it provides a rich set of tools for generating documentation, mocking and more. For mocking we use <a href=\"/techradar/tools/wiremock.html\">Wiremock</a>, for example.</p>\n<p>Related to the &quot;API-First&quot; approach is the &quot;Headless&quot; approach where an existing application (with or without existing API) is used as a backend for a separate frontend. We used this with sucess for Magento-based E-Commerce platforms. This allows encapsulating the core features of that application, while integrating it into a larger landscape of components using its API as a unified way to interact between components. Decoupling the core logic from its presentation layer allows picking the best technology stack for the various parts independently.</p>\n<p>For further reading see:</p>\n<ul>\n<li><a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://www.programmableweb.com/api-university/understanding-api-first-design\">Understanding API First Design</a></li>\n<li><a target=\"_blank\" rel=\"noopener noreferrer\" href=\"http://www.techradar.com/news/software/applications/when-crafting-your-api-strategy-put-design-first-1262043?src=rss&amp;attr=all\">When crafting your API strategy, put design first</a></li>\n</ul>\n"

A team that consumes the API can start working directly after the API design because it can easily be mocked.</p>\n<p>There are several tools for modelling an API, but here at AOE we mainly use <a href=\"/techradar/tools/raml.html\">RAML</a> as it provides a rich set of tools for generating documentation, mocking and more. For mocking we use <a href=\"/techradar/tools/wiremock.html\">Wiremock</a>, for example.</p>\n<p>Related to the &quot;API-First&quot; approach is the &quot;Headless&quot; approach where an existing application (with or without existing API) is used as a backend for a separate frontend. We used this with sucess for Magento-based E-Commerce platforms. This allows encapsulating the core features of that application, while integrating it into a larger landscape of components using its API as a unified way to interact between components. Decoupling the core logic from its presentation layer allows picking the best technology stack for the various parts independently.</p>\n<p>For further reading see:</p>\n<ul>\n<li><a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://www.programmableweb.com/api-university/understanding-api-first-design\">Understanding API First Design</a></li>\n<li><a target=\"_blank\" rel=\"noopener noreferrer\" href=\"http://www.techradar.com/news/software/applications/when-crafting-your-api-strategy-put-design-first-1262043?src=rss&amp;attr=all\">When crafting your API strategy, put design first</a></li>\n</ul>\n",

A fine grained security system enables easy management of which artifacts are available to whom.\nThe artifacts are exposed via an HTTP(S)-Url Artifactory, which can generate package-manager compatible manifests for the repositories. AOE utilizes Artifactory to serve Maven, Apt, Npm, Composer and Docker Repositories.</p>\n<p>In addition to storing own assets, Artifactory is able to proxy remote Repository for and cache resolved artifacts locally.\nThis results in an increased build performance and decouples builds from external service dependencies and ensures builds still work even if they utilize outdated dependencies that might not be publicly available anymore.</p>\n<p>Artifactory provides a powerful REST-API for managing Artifacts including a powerful search AQL. It is utilized to provide complex release processes based on QA-Attributes on an artifact level.</p>\n<p>Artifactory at AOE currently comes with some problems, too:</p>\n<ul>\n<li>Cleanup in Artifactory has to be done manually. Therefore, if every build is pushed to Artifactory it currently pollutes disk space since old or unused versions are never removed.</li>\n<li>The Composer Integration mirroring github proves to be slower than directly connecting to github.</li>\n</ul>\n<p>AOE is using the Professional version for a central instance that can be used by different teams. We encourage teams to use Artifactory instead of Jenkins to store and manage build artifacts - and to take care of cleaning up old artifacts automatically.</p>\n"

The result of splitting our software and infrastructure in smaller parts, is the need to communicate with each other. This can be done by direct communication or by message-based asynchronouous communication. While synchronuous communication allows for more plannable &quot;real-time&quot; response times of the overall systems, asynchronouos communication increases the resilience and stability of the system significantly and allows one to use other integration and scaling patterns.

"body": "<p>In <a href=\"/techradar/methods-and-patterns/microservices.html\">Microservices</a> we have already covered the trend that modern architectures are moving away more and more from big monolithic applications to distributed software suites. The result of splitting our software and infrastructure in smaller parts, is the need to communicate with each other. This can be done by direct communication or by message-based asynchronouous communication. While synchronuous communication allows for more plannable &quot;real-time&quot; response times of the overall systems, asynchronouos communication increases the resilience and stability of the system significantly and allows one to use other integration and scaling patterns. However, it often comes with additional complexity.</p>\n<p>Most of the IaaS Cloud providers offer messaging services such as AWS SQS which provide the possibility to decouple our infrastructure via Messaging. Also, we use <a href=\"/techradar/tools/rabbitmq.html\">RabbitMQ</a> as a Messaging and Broker solution within our applications. The decision of using messaging and messaging patterns as an integration strategy can be made as part of <a href=\"/techradar/methods-and-patterns/strategic-domain-driven-design.html\">strategic design</a> considerations.</p>\n",

Also, also it can be used to extract useful KPIs or to visualize information on dashboards.</p>\n<p>The abbreviation &quot;<a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://www.elastic.co/products\">ELK</a> Stack&quot; stands for the Tools <u>E</u>lasticsearch, <u>L</u>ogstash and <u>K</u>ibana: Together, they provide a solution for collecting data the ability to search, visualize and analyze data in real time.</p>\n<p>Logstash is used to process and forward different data (or logfile) formats. <u>E</u>lasticsearch is used as a search index and together with the Kibana plugin you can configure highly individual dashboards. Recently, there are also the Beats Tools joining this toolstack to ship data to Elasticsearch.</p>\n<p>We have been using the ELK Stack for several years now in several projects and different infrastructure setups - we use it to visualize traffic, certain KPIs or just to analyze and search in application logs. We encourage all teams to use such a solution and take care to write useful logs in your applications.</p>\n",

"body": "<p><a target=\"_blank\" rel=\"noopener noreferrer\" href=\"http://gatling.io/\">Gatling</a> is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance.</p>\n<p>Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"http://gatling.io/docs/current/\">JMS support</a>.</p>\n<p>Gatling is built with <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://extranet.aoe.com/confluence/display/knowledge/Scala+Lang\">Scala Lang</a> and <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://extranet.aoe.com/confluence/display/knowledge/Akka\">Akka</a>. By making good use of Scala&#39;s native language features (such as as the extensive type system), it makes writing tests feel natural and expressive, instead of writing load tests based on a DSL encoded in some special syntax.</p>\n<p>This allows us to use all native Scala features to work with, with the focus on the ability to structure your tests as pure code, and actually unit test your load tests.</p>\n<p>Besides the very good performance, we definitely like the pure code-based approach. Gatling creates HTML-based reports with nice graphs and metrics about how and what was tested.</p>\n<p>We use Gatling as an alternative to Jmeter with success in some of our projects. We encourage teams to try Gatling for future load testing. There is an integrated test recorder similiar to what other test frameworks have to get you started with a basic test case.</p>\n"

Also, more and more applications, such as Gitlab, incorporate Go-based services to &quot;off load&quot; heavy work.</p>\n<p>Go, as a programming language, has some very interesting features such as native support for concurrency (go routines), static compiled binaries with a very small memory footprint, cross compiling and much more. A big advantage of Go is the very flat learning curve, which allows developers from more dynamic languages such as PHP to be proficient in a very short time.</p>\n<p>If you want to get a feeling for Go, you should start with the <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://tour.golang.org/welcome/1\">online tour</a>, within a day you&#39;ll have a good understanding of the core concepts, syntax, etc. - that is also because the language often tries to provide only one simple way of doing things; an example for this is that code formatting and styling is defined (yet not enforced as in Python). Part of this is also that Go itself is very opinionated: So, for example, for object oriented programming in Go, composition is the prefered way of defining data structures, and some might miss advanced concepts such as inheritance.</p>\n<p>We currently use Go for projects and microservices where we need flexibility and performance.</p>\n"

Currently there is support for languages such as C++, Java, Python, Go and many more.\nThe shared language-neutral protobuf definition allows you to create all code for all languages automatically and helps with the interoperability of different systems.</p>\n<p>From a technical point of view, gRPC uses HTTP/2 as a transport, directly benefitting from the default TLS encryption.\nBesides gRPC, other frameworks also use protobuf RPC definitions. These frameworks include twirp from twitch, which makes it easy to change the transport/control layer with only very small changes to the application code.</p>\n<p>We at AOE plan to assess gRPC for microservice architectures which are more RPC style and less REST style.</p>\n"

A consumer must only be familiar with the basics of hypermedia.</p>\n<p>Let&#39;s assume we have a bank account and an action to deposit money on that account.

Terraform comes with a lot of concepts that make managing environments easier out of the box and nicely embeds into other related tools. Also, Terraform allows you to manage a variety of different infrastructure providers.</p>\n<p>Infrastructure as code should cover everything from orchestration of your infrastructure resources, networking and provisioning as well as monitoring setup.

"body": "<p>Ports and Adapters is an architecture or layering approach for software design. As with other layering approaches, it seperates different concerns in different layers, where dependencies are only allowed from the outside to the inside.</p>\n<p>We use &quot;ports and adapters&quot; with success for (larger) applications, which contain certain business logic and/or provide several ways to access the services.\nWe often use the approach hand-in-hand with Domain Driven Design. In comparison with other layering patterns (e.g. layered architecture) it allows you to have a true technology-free core (domain) model. Why? Because, with the concept of &quot;secondary ports&quot; (=interfaces), it inverts the control and allows outer layers to provide adapters (=implementations of the defined interface).\nIt also defines clear boundaries regarding where to put what logic of your application.</p>\n<p>You can find out more about the details and its origins in well-known blog posts such as <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://8thlight.com/blog/uncle-bob/2012/08/13/the-clean-architecture.html\">The Clean Architecture</a> or <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"http://alistair.cockburn.us/Hexagonal+architecture\">Hexagonal architecture</a></p>\n<p>In short, here is how we often layer such applications:</p>\n<ul>\n<li>Domain:<ul>\n<li>Is the inner layer and contains the technology-free domain model</li>\n<li>Often uses building blocks from Domain Driven Design</li>\n<li>It defines primary and secondary ports. (E.g. a secondary port is in &quot;interface&quot; that needs to be implemented in the infrastructure layer.)</li>\n</ul>\n</li>\n<li>Application:<ul>\n<li>Contains the Application&#39;s API and Services, that are developed around the use cases in the application requirements.</li>\n<li>These use cases orchestrate the flow of data to and from the domain</li>\n</ul>\n</li>\n<li>Interfaces:<ul>\n<li>Contain everything required to convert data from the format most-convenient for the use cases (e.g. in the application layer) to the format required for external agency/access</li>\n<li>e.g. (Web) Controllers / DTOs for handling forms, etc.</li>\n</ul>\n</li>\n<li>Infrastructure:<ul>\n<li>This layer is where all the (technical) details live. (The database and persistence is a detail, the communication format and mappings with external services is a detail, etc.)</li>\n<li>In this layer you typically have adapters for the secondary ports that have been defined in the layers below. (e.g. an Implementation of a Repository interface from the Domain layer)</li>\n</ul>\n</li>\n</ul>\n<p>These layers belong to every bounded context (modules) inside the application.</p>\n<p>Are you searching for a potential timeless architecture for your critical application? Try implementing a potent technology-free domain model in the core layer and use ports and adapters to layer your application.</p>\n"

"body": "<p>RabbitMQ is an Open Source message broker - implementing the Advanced Message Queuing Protocol (AMQP) protocol. It provides a reliable and scalable way to transport data between loosely coupled applications, using different EAI patterns such as the Publish &amp; Subscriber pattern. AMQP supports direct and fan-out exchanges (broadcasts) as well as topics. Queuing mechanisms allow for robust architectures, mitigating the risks of application downtimes. Typically, a RabbitMQ server can easily buffer millions of messages. RabbitMQ supports JMS in addition to AMQP. It is not intended to use JMS for new systems, but it makes RabbitMQ useful for integrating legacy systems.</p>\n<p>There are several alternative solutions to RabbitMQ, e. g. the free Apache ActiveMQ, which is integrated in <a href=\"/techradar/tools/anypoint-platform.html\">Anypoint platform</a>. ActiveMQ implements a somewhat simpler routing concept than RabbitMQ, but offers more protocols. Commercial products in this area are offered by IBM (Websphere MQ), Fiorano and almost every vendor of ESB products.</p>\n<p>We use RabbitMQ internally for transferring messages safely in our logging ecosystem between <a href=\"/techradar/platforms-and-aoe-services/elk-stack.html\">Logstash</a> proxies and servers using direct and fan-out exchanges for delivering messages to appropriate destinations. RabbitMQ is also used to asynchronously trigger Jenkins jobs from our SCMs to mitigate heavy load on the SCMs, usually caused by Jenkins polls for SCM changes. Additionally, some critical events for monitoring are using RabbitMQ for guaranteed notification. </p>\n<p>RabbitMQ is rated &quot;Trial&quot;. It fits into our approach to build robust, <a href=\"/techradar/methods-and-patterns/resilience-thinking.html\">resilient systems</a> and use <a href=\"/techradar/methods-and-patterns/decoupling-infrastructure-via-messaging.html\">asyncronous messages</a> for loosely coupled communications between components. In practice, RabbitMQ proved to be stable and dealt well with service interruptions from failures and maintenance slots. A common pain point is RabbitMQ as a single point of failure disrupting the data flow in a system. This issue is currently approached by setting up a HA cluster for RabbitMQ. The outcome of this approach will clarify the extent of future usage of RabbitMQ in our systems.</p>\n"

You can achieve this pattern without special tools - but this concept of settings injection also works with tools such as <a href=\"/techradar/tools/consul.html\">Consul</a>, <a href=\"/techradar/platforms-and-aoe-services/kubernetes.html\">kubernetes</a> (with configMaps and secrets) or <a target=\"_blank\" rel=\"noopener noreferrer\" href=\"https://github.com/AOEpeople/YAD\">YAD</a>.</p>\n<p>In this manner, the build package can be independent from the environment it&#39;s being deployed to - making it easier to follow the &quot;Build once, deploy often&quot; CI/CD principle.</p>\n",

It also has an assortment of other useful features including record/playback of interactions with other APIs, injection of faults and delays, simulation of stateful behavior.</p>\n<p>It can be used as a library by any JVM application, or run as a standalone process either on the same host as the system under test or a remote server. All of WireMock&#39;s features are accessible via its REST (JSON) interface and its Java API. Additionally, the mock server can be configured via JSON files.</p>\n<p>At AOE, we use WireMock as a standalone server to mock APIs that are outside our system context to get a stable environment for testing and rapid feedback. Besides the decoupled test and development advantages, the mocked APIs can also be used in contract-based tests. We also use embedded WireMock in functional tests to stub external services. The explicit test of faults are especially helpful in building and testing the <a href=\"/techradar/methods-and-patterns/resilience-thinking.html\">resilience of your application</a>.</p>\n<p>Because of the features such as flexible deployment, powerful request matching and record/payback interactions, as well as the fact that the server runs stable in our project environments, we classify WireMock as <em>trial</em>.</p>\n"
