Docker image checks: Quality, security, up-to-dateness, layers and inheritance

Docker images have become the valuta franca in the cloud and container platform world. Although on the path to vendor-neutral standardisation (e.g. with OCI also being in Docker Hub for a year now), developers for now have settled on plain Docker as de-facto standard due to the vast ecosystem of base images and dependency images which speed up the rapid prototyping of complex scalable applications. From a production-grade DevOps perspective, a key concern is then to be assured that the containers used are of high quality, not infected by security vulnerabilities, and still containing the latest features available. In this blog post, a novel approach to visualise the situation around a particular container image is presented.

Reflections on Teaching Serverless and Cloud-native Application Development

With the proliferation of hybrid cloud, cross-cloud and post-cloud environments, finding the right concepts and tools to produce mixed-technology applications and services remains challenging. At Zurich University of Applied Sciences, a course on Serverless and Cloud-native Application Development (SCAD) prepares bachelor students in computer science for facing these challenges. We argue that this is the first such lecture in Switzerland and probably even in the world. Three years after reflecting on Internet Service Prototyping teaching, this mid-semester blog post sums up the evolution of the field, explains the course design of SCAD and briefly reports on the lab results.

Presenting the MAO Orchestrator

The MAO-MAO research collaboration aims to provide metrics, analytics and quality control for microservice artefacts of all kinds, including but not limited to, Docker containers, Helm charts and AWS Lambda functions. As such, an integral part of prior research has been the various periodic data collection experiments, gathering metadata and conducting automatic code analysis.

However, the ambition of the project to collect data consistently, combined with the need for the collaborators to be able to use each other’s tools and access each other’s data, have created a need for a collaboration framework and distributed execution platform.

In response to this need, we present the first release of the MAO Orchestrator, a tool designed to run these experiments in a smart way and on a schedule, within a federated cluster across research sites. As a plus, there is nothing implementation-wise tying it to the existing assessment tools, so it is reusable for any use-case that requires collaboratively running periodic experiments.

Three upcoming workshops/tutorials on cloud-native and serverless application technologies

The Service Prototyping Lab will offer three in-depth presentations and hands-on sessions on several of its research topics and recent results in September and October. We hope to demonstrate valuable work and get feedback for our future research.

FI, September 2-4, 2019: «Summer School on Software Evolution: From Monolithic to Cloud-Native» @ Inforte Tampere – More information

CH, September 10, 2019: «Datengestützte Qualitätsanalyse von Microservice-Artefakten in der Softwareentwicklung» @ CH Open Workshop Days Rapperswil (in German with co-instructor support in English) – More information

DE, October 25, 2015: «CI/CD-integrated quality assessment of microservice implementation artefacts» @ Software QS-Tag Frankfurt – More information

Quality analysis of dapps: Just like cloud apps?

Looking into a possible post-cloud world, we see mentions of different computing paradigms, many of them based on decentralised structures to overcome scalability and user control limitations. Among them is blockchain-as-a-service (BCaaS or BaaS), mimicking the platform-as-a-service (PaaS) user experience for both application providers and consumers. In PaaS, providers first sign up and subscribe to the platform, then design and build their applications and deploy them to the platform where it is executing either permanently or upon incoming network requests or other event triggers. Additionally, developers may advertise their apps at technology-specific hubs such as AWS SAR or Helm Hub. Consumers then adhere to the application terms, which might require a sign-up at the provider site, before being able to invoke and make use of the application.

First International Workshop on Cloud-Native Applications Design and Experience — CNAX 2018

Our SPLab organised a full day workshop on cloud-native applications (see the web page and call for papers of the CNAX 2018) within the IEEE/ACM UCC/BDCAT 2018 umbrella.

The workshop was organised in collaboration with Ivo Krka from Google and also supported by Jorge Cardoso from Huawei. The blending of industry and academic research has always been a key point in cloud-native work which relies heavily on fast-paced innovation.
