Monoliths Aren’t Inherently Bad

Leider ist der Eintrag nur auf English verfügbar.Self-professed minimalist developer Kelsey Hightower a few months ago wrote about monoliths being the future. The microservice design pattern has been trending in software development for quite some now. Unfortunately, more often than not it's been indiscriminately treated as a panacea to every software architecture and design problem out there. Microservices can help with one aspect specifically: Reducing deployment risk. If you have a large monolith and frequently need to make changes to a specific part or ...

Running A Local Angular Development Environment Behind A Spring Cloud Gateway Service

Leider ist der Eintrag nur auf English verfügbar.Having multiple microservices running behind a reverse proxy / API gateway in lieu of a single monolithic back-end application is a common pattern these days. With such an architecture it often comes in handy to have an Angular application that serves as a front-end for such a modularised back-end be served from behind a reverse proxy running locally as well in order to treat it is if it were running on the same host and ...

Cloud Design Pattern Library by Microsoft

Leider ist der Eintrag nur auf English verfügbar.Microsoft maintains an extensive library of cloud design patterns. Whether you create applications that run on AWS, Microsoft Azure or Google Cloud Platform, use platforms such as Heroku or you develop enterprise applications which run on on-premise cloud networks within a corporate intranet, cloud computing becomes ever more crucial to providing business value through software. Hence, it's not only expedient to know about the classic relatively low-level GoF design patterns or Martin Fowler's Patterns of Enterprise ...

A Quick Reminder About the Relevance of Latency in Computer Systems

Leider ist der Eintrag nur auf English verfügbar.This Gist by Jonas Bonér gives a quick overview of the different latency values for accessing different kinds of data storage and memory systems and the order of magnitude by which they differ: Latency Numbers Every Programmer Should Know Putting this in perspective is particularly important in the context of service-based architectures like RESTful web services, Microservices and similar approaches. All-out service-based architectures might be the right the solution to some scalability and deployment problems in complex ...

Microservices and Decoupling Front-end Components

Leider ist der Eintrag nur auf English verfügbar.Microservices have become a common design pattern for splitting up and modularising monolithic applications. The indiscriminate application of this particular design pattern is quite a bit worrying, though. A few months ago I gave this answer to the question what the biggest struggle with Microservices is: Convincing people that microservices are not a cure-all but just another design pattern. You have to start out with a monolith and only if you realise along the way that ...

Using Netflix Zuul As a Reverse Proxy / API Gateway

Leider ist der Eintrag nur auf English verfügbar.Zuul, which like the service discovery tool Eureka and the fault tolerance library Hystrix is part of Netflix' cloud orchestration stack, is a reverse proxy / API gateway. A reverse proxy conceptually works like this: A reverse proxy allows you to route requests to a single domain to multiple backing services behind that proxy. This can be conducive in situations where you want to break up your application into several loosely-coupled components that externally, that is ...

Deploying Spring Boot applications as old-fashioned WAR files

Leider ist der Eintrag nur auf English verfügbar.Spring Boot is an opinionated convention-over-configuration framework for creating stand-alone Spring-based Java applications. Its objective is to provide you with a preselected best practice choice of libraries (both from the Spring platform and by third parties) for a given task, e.g. building a web application that connects to a database and provides REST resources creating a scheduled batch task that exports and aggregates data from various data sources providing an API that connects to SOAP Web Services It both ...

Matt Ranney @ GOTO 2016: What I Wish I Had Known Before Scaling Uber to 1000 Services

Leider ist der Eintrag nur auf English verfügbar.At the GOTO Chicago 2016 enterprise software conference Matt Ranney, chief systems architect at Uber and co-founder of Voxer gave a presentation on what they learned from adopting microservices on a massive scale at Uber: "To Keep up with Uber's growth, we've embraced microservices in a big way. This has led to an explosion of new services, crossing over 1,000 production services in early March 2016. Along the way we've learned a lot [ ... ...
