Applications claimed to have been built using Domain-Driven Design (DDD) in reality often consists of entities or DTOs separating data and logic together with services containing a mix of business and infrastructure logic, Gabriel Schenker states, noting that this also often applies early on to projects building new applications. Lack of knowledge is one major reason for this, Schenker believes.
At Craft Conference 2015, Adrian Trenaman discussed the evolution of the Gilt.com architecture from a monolithic Ruby on Rails application to a cloud-based microservice ‘lots of small applications’ platform utilising Scala, Docker and AWS. Trenaman shared both technical and organisational lessons learnt from the past eight years, as Gilt has grown from a startup to a $1B company.
At Craft Conference 2015 in Budapest, Mary Poppendieck discussed the ‘new software development game’ and offered advice on how best to utilise containers, microservices and consumer-based contract tests to lower friction and limit risk within software systems.
Big data vendors Hortonworks, IBM, and Pivotal recently announced that their Hadoop based platform products will use the common Open Data Platform (ODP). They made the announcement at the recent HadoopSummit Europe Conference of the open platform which includes Apache Hadoop 2.6 (HDFS, YARN, and MapReduce) and Apache Ambari software.
Programming frameworks, containers, and application platforms are some of the components that make up the modern application architecture. Chip Childers of Cloud Foundry Foundation spoke at ApacheCon Conference last week about modern application architecture and the cloud native application platform.
At Craft Conference in Budapest, Dan North and Jessica Kerr presented a keynote session which cautioned developers that complexity is often found outside of the code. The key messages included: identify and manage areas of complexity; treat learning as a first-class citizen; focus on working to sustainably minimise lead time to business impact; and nurture a supportive team and community.
We published in 2014 the results of TechEmpower’s benchmark of various web frameworks, a term including web platforms and micro-frameworks. A year later, they have published a new set of results outlining important changes in the performance of top 10 web frameworks.
Google has published the paper "Large-scale cluster management at Google with Borg", unveiling details on a technology that was very little spoken about in the past.
Standardizing on common models for business objects that are exchanged within an enterprise, e.g. Customer, Order and Product together with the attributes and associations they have, might seem compelling but for Stefan Tilkov this creation of Canonical Data Models (CDMs) is a horrible idea which he strongly advices against.
Recently Adrian Cockcroft gave an interview to ActiveState's John Wetherill about microservices. In it he talks about how polyglot fits into microservices and the impact on him when he head that companies such as Target and Macy's, as well as Homeland Security had adopted that architectural approach.
AnyPresence, one of the leading MBaaS players has launched JustAPIs, a platform for building and deploying RESTful APIs.
After three developer previews, six release candidates and over 1500 closed tickets the Apache foundation has announced version 1.0 of Apache HBase, a NoSQL database in the Hadoop ecosystem. After more than 7 years of active development, the team behind HBase felt that the project had matured and stabilized enough to warrant a 1.0 version.
At the inaugural O’Reilly Software Architecture conference, Raffi Krikorian discussed strategies and tactics for technical leads and architects who are undertaking a system rewrite. Drawing on his experience as VP of Twitter Engineering, Krikorian discussed a twelve point plan for managing a re-architecting, including defining “done”, instrumenting existing systems, and enforcing code quality.
Google has recently published a paper providing architectural guidelines for creating a scalable and resilient solution running on their cloud platform. This article digests the respective paper extracting the main ideas and advice. These guidelines can be used with minor changes for deploying web applications on other clouds.
A service is a logical construct owning a business capability and made up of internal autonomous components or microservices that together fulfil the responsibilities of the service, Jeppe Cramon suggests continuing a previous series of blog posts clarifying his view on building services around business capabilities and bounded contexts.
