Running a few containers? No problem. Running hundreds or thousands? Enter the container orchestrator. Let’s take a look at the characteristics of the three most popular container orchestrators and what makes them alike, yet unique.

Security has and continues to be an impediment to container adoption. Whether containers are less or more secure than their virtual machine counterparts is a topic of continued debate.

Like any debate, there are merits to arguments on both sides with a bit of FUD interlaced. Many efforts have been undertaken within the container ecosystem to educate adopters and improve their comprehension of available tooling and security postures within platforms and offerings—be that in the form of static analysis (image scanning), runtime vulnerability detection, provenance (image signing), fine-grained authorization, cryptographic verification, etc.

Following on our previous discussion surveying the projects supporting applications within OpenStack, let’s continue our review with an in-depth look at the OpenStack-native Application Catalog: Murano, currently an incubation status project, having seen its functionality and core services integration advanced over the past few OpenStack releases.

OpenStack Centric Applications - Murano

What is it?

An application catalog developed by Mirantis, HP and others (now including Cisco), that allows application developers and cloud administrators to publish applications in a categorized catalog to be perused and deployed by application consumers. The selection of applications available within the catalog is intended to be that of released versions (ready-state) of applications (cloud-native or enterprise-architected), not application versions that are mid-development. Ideally, these are applications ready to be consumed and run by application users. Continue reading »

Cloud infrastructure is useless without applications running atop, providing business serviOpenStack Applicationsces and solving customer needs. So, as applications ascend to the throne as the rightful king of cloud, focus sharpens on their support within OpenStack-based clouds. With this focus, let’s walk through a survey of components and projects supporting applications in OpenStack, understanding what a day in the life of an application in OpenStack is like. We’ll start with an overview of the application ecosystem comprised of a number of supporting projects. In the ecosystem overview below, relevant OpenStack projects are presented in context of existing, similar technologies with which you may be familiar. These similar technologies both under and overlap functionality of the respective OpenStack project, but are shown to hasten your general understanding of which bucket these projects fall into by way of tech you may already know (so, add a pinch of salt when considering relevancy of suggested affiliated technologies).
