Istio – Service Mesh for Kubernetes and Cloud-native Systems

Microservices, especially cloud-native, container-based microservices have radically changed how applications are built and deployed. This shift has been driven by a number of positives that container-based microservices provide (eg. speed, portability, …). However, traditional monitoring tools don’t’ work with these new systems. The service mesh concept (and in particular the …

The new way to Build Cloud-native Applications

What are microservices? Do they have to be small? What do APIs have to do with all this? Microservice application architecture is the current favorite, new model for application development in general and Cloud-native applications in particular. But what are they, how do they work and why are they better …

Unikernels - are they just a new kind of Linux Container?

Are they really just Containers v2.0?

Unikernels – will they be the next hype thing after Containers or are they “just” Containers v2.0? How do they compare to Containers, Bare Metal or Serverless compute models? Kumulus Tech CTO, Robert Starmer, breaks down how they are like, yet differ from, Linux Containers and where their value proposition …

AKA “Function-as-a-Service”

Serverless Computing- a powerful Cloud function, but also the latest confusing buzzword in the world of Cloud computing and application development. Perhaps better described a “Function-as-a-Service,” this tool allows developers to focus on application development rather than the infrastructure needed to support an application. In this episode, Robert Starmer, Kumulus …

Public Cloud is _not_ the answer.

The pundits are wrong. The Public vs Private vs Hybrid argument is sort of like arguing whether a truck, sedan or SUV is the car to own. Kumulus Technologies CTO, Robert Starmer, explains why like the car analogy, each deployment or service model has distinctive pros and cons that make …

Saas on OpenStack (Software-as-a-Service)

Using OpenStack to Support a SaaS Cloud

OpenStack is, first and foremost, built to provide an Infrastructure-as-a-Service, however, its versatility has lent it to breaking out of that box and being used to build and support both PaaS and SaaS clouds. In this episode Robert Starmer, the CTO of Kumulus Technologies discusses how SaaS works and how …

How OpenStack Supports PaaS Clouds

Platform-as-a-Service (PaaS) is “the Developer’s Cloud” – a cloud computing service model that provides software developers with the tools they need to build and deploy applications, without the need to worry about managing infrastructure. OpenStack, though designed as an Infrastructure-as-a-Service platform has several PaaS systems that integrate with it. In …

OpenStack Kubernetes IaaS is this a Cloud Computing management system whose time has come?

SF Bay OpenStack Meetup – OpenStack on Kubernetes?

This two-part session at the SFBay OpenStack Meetup looks at the idea of an Openstack Kubernetes IaaS. OpenStack was designed as a virtual server-focused IaaS platform. Kubernetes is the Google-invented, open source Container management platform. The meetup starts with a brief discussion by John Starmer, Kumulus Tech’s Director of Education, …
