🗂 The future of Kubernetes is Virtual Machines
Multi-tenancy ain’t easy: > The Kubernetes cluster itself becomes the line of “Hard Tenanacy”. This leads to the emerging pattern of “many clusters” rather than “one big shared” cluster. Its not uncommon to see customers of Google’s GKE Service have dozens of Kubernetes clusters deployed for multiple teams. Often each developer gets their own cluster.…

VMware uses NSX for Istio
> The microservice architecture, which breaks complex applications into sets of single-purpose networked components, can be a challenge to manage, as each microservice must be instrumented, secured and locatable in a dynamically reconfiguring network. In addition, multiple copies of microservices may be run in parallel, to meet the demands of a growing demand. Their traffic…

Link: Cloud Foundry Cult
Owen covers CF Summit Basel: “The users we spoke with didn’t just see it as a PaaS – it was the underlying philosophy of application delivery and management upon which future developments would be based. The Foundation claims Cloud Foundry saves, on average, 10 weeks of development time and $100,000 per app development cycle. In…

Link: Pivotal Cloud Foundry 2.3
A laundry list of new feature and services in the software I market around. There’s a lot of .Net expansion, adding some standard platform services (like a task scheduler), and Morlock stuff like multi-install (would you say “zone”?) OpenStack, and Kubernetes and embedded OS update: Original source: Pivotal Cloud Foundry 2.3

Link: VMworld 2018: VMware Wants to Re-Architect Your Containers for NSX – The New Stack
“The developer shouldn’t have to know how to program NSX, or know what the security isolation boundaries are,” continued Fazzone. “But they should know that their organization has taken steps to unify the networking approach between the containerized applications and the traditional applications running in VMs, and take advantage of that ‘service’ offered by IT…

Link: Think in Products, Not Projects
“In a high level, projects are local optimization efforts. We get a group of people who create new (or improve existing) functionality for our customers and then we pass that onto a team that has no idea why the change was made and how this change was solutioned/implemented. Very often, the quality is low and…

Link: Istio Aims To Be The Mesh Plumbing For Containerized Microservices
“The latter piece can be the tricky one when using containers to develop microservices. How do you link up all the component parts when they may be spread across a cluster of server nodes, and instances of them are continually popping up and later being retired as they are replaced by updated versions? In a…

“Also, it is recommended to not deploy to all production environments in one go, exposing all the customers to the changes. A gradual rollout that exposes the changes to customers over a period, thereby implicitly validating the changes in production with a smaller set of customers at a time… As an example, for an application…

Link: Istio sets sail as Red Hat renovates OpenShift container ship
“The software serves as a management mechanism for distributed microservices, providing capabilities like traffic management, service identity and security, policy enforcement and telemetry among apps running across multiple Kubernetes clusters and hosts.” Original source: Istio sets sail as Red Hat renovates OpenShift container ship

Link: Goodbye Microservices: From 100s of problem children to 1 superstar
“Briefly, microservices is a service-oriented software architecture in which server-side applications are constructed by combining many single-purpose, low-footprint network services. The touted benefits are improved modularity, reduced testing burden, better functional composition, environmental isolation, and development team autonomy. The opposite is a Monolithic architecture, where a large amount of functionality lives in a single service…

Link: Will Containers Replace VMs?
“One of the most important benefits containers provide is that once you have a containerized application, it runs in exactly the same environment at every stage of the lifecycle, from initial development through testing and deployment, so you get mobility of a workload at every stage of its lifecycle,” said Iams. “In the past, you…

Link: Press 1 for automagic K8s cluster. Press 2 or 3 for complex Kubernetes
“many developers want to adopt Kubernetes, but have little interest in provisioning the infrastructure, little skill at doing so optimally and no appetite to hire people to do either chore.” Yeah. In other words: infrastructure software, a concise history. Original source: Press 1 for automagic K8s cluster. Press 2 or 3 for complex Kubernetes

Link: Serverless Impacts on Business, Process and Culture
‘Sharples said the main interest stems from an enterprise love of microservices, where incremental delivery, agility and faster delivery are being embraced. “But we see adopters struggle with the operational complexity of managing and monitoring distributed systems, and that is where serverless has gotten their attention. You get the microservices benefits, but from a developer…

In their PCF setup, T-Mobile has only 10 operators supporting 18,000 containers doing 10,000 transactions/second. This is spread over 1,700 developers. So: “T-Mobile reports a 170:1 developer to operator ratio.” Original source: CF Summit Boston — Day 2 Wrap-Up – Brian McClain – Medium
