One of the desirable properties which users expect in a modern cloud-hosted application is portability. Users want to migrate portable applications between private and public clouds or between different cloud regions. With container images as portable application implementations and emerging sophisticated container runtimes, this should be an easy task. But when a containerised application starts […]
How are cloud-native applications engineered? In contrast to the increasing popularity of the topic, there are surprisingly few reference applications available. In the previous blogpost we described a first version of a prototypical document management application consisting of composed containers which is called ARKIS Microservices. We elaborated on the challenges involved when designing and developing […]
In the context of the FINEXT project, we have been reviewing Rancher as a tool to support easy deployment of FIWARE components. (Our colleagues in the project have more experience with this tool – we’re still climbing the learning curve). Here are a few observations relating to Rancher. The primary problem that Rancher solves is […]
Document management is an established software-powered business domain. As with most software applications, an ongoing trend is to move the functionality of document management systems (DMS) and related functionality (Enterprise Content Management – ECM, Content Services – CS) into well-defined services, primarily in cloud environments, resulting in cloud-native document management systems/services (CNDMS). In the context […]
Following the series that we started with the Vamp Blog post, we proceed to take a look of one more of the container management tools which includes running a simple practical example while we pay attention to the main advantages and limitations. This series happens in the context of the work on cloud-native applications in […]
In the world of containerized architectures, there are different and new container deployment and orchestration tools which help turning monolithic applications into running composite microservices. Some of them are intended to be used in a development environment like Docker-Compose or in a production environment like Kubernetes, Docker-Swarm or Marathon. Also, we can observe some tools […]
For reliable, user-controlled and trustworthy file storage in the cloud, free software prototypes like NubiSave have become great tools to investigate and lift the barrier towards acceptable migration paths. For structured data storage and processing, several approaches to database-as-a-service (DBaaS) have been proposed by researchers and developers but a clear recommendation of how to best […]
In the context of the Cloud Native Applications (CNA) Seed Project we are working on migrating an open source CRM application into to the cloud. After enabling horizontal scalabilty of the original application and moving it onto our OpenStack cloud with the help of CoreOS (etcd, fleet) and docker we’ve now just finished adding the […]
