  • 3 tips for moving your team to a microservices architecture

    Microservices are gaining in popularity and providing new ways for tech companies to improve their services for end users. But what impact does the shift to microservices have on team culture and morale? What issues should CTOs, developers, and project managers consider when the best technological choice is a move to microservices?

    Below you’ll find key advice and insight from CTOs and project leads as they reflect on their experiences with team culture and microservices.

  • Microsoft's Azure Kubernetes Service mucked my cluster!

    Microsoft's Azure Kubernetes Service (AKS) was launched to world+dog in June, however, a few disgruntled customers say the managed container confection isn't fully baked yet.

    In a blog post published on Monday, Prashant Deva, creator of an app and infrastructure monitoring service called DripStat, savaged AKS, calling it "an alpha service marked as GA [generally available] by Microsoft."

    Deva said he moved his company's production workload to AKS last month, and has been plagued by random DNS failures for domains outside of Azure and hostnames inside the Azure Virtual Network.

    He characterized the response from Microsoft support – advice not to use excessive memory and CPU resources – as ridiculous, and said Microsoft failed to respond when told the DNS issues occurred mainly during application startup when memory and CPU usage is minimal.

  • How to Lead a Disaster Recovery Exercise For Your On-Call Team

    On-call teams at startups have three big problems: they’re small, they cover a wide breadth of infrastructure, and the last two points usually imply that they lack the bandwidth to maintain and write documentation for a suite of DevOps tools. At SigOpt, our on-call team tackles these challenges with a biannual “disaster recovery exercise”, or simulated outage.

    In this blog post I will show you what a disaster recovery exercise is, how it can diagnose weak points in your infrastructure, and how it can be a learning experience for your on-call team. I hope that by the end you’ll consider running a disaster recovery exercise for your on-call team!

  • Istio Service Mesh Advances to Production

    Istio, the “service mesh” intended to connect application components and thereby boost the capabilities of the Kubernetes cluster orchestrator, has advanced over the past year as a way of managing increasingly popular micro-services.

    Partners Google Cloud, IBM (NYSE: IBM), ride sharer Lyft and Red Hat’s CoreOS unit along with other open source developers announced the 1.0 release of Istio on Tuesday (July 31). Among the goals is simplifying enterprise deployment of micro-services and allowing developers to add, change and route them within cloud-native applications. This, proponents said, can be done without having to update code or rebuild the underlying application containers.

  • Google advances Istio – this could be bigger than Kubernetes and serverless

    As modern digital computing infrastructure continues to evolve, new layers of automation enable increasingly rapid change and adaptation. Once containerization had made it possible to deploy new capabilities in seconds, then the advent of Kubernetes and similar tools added a layer of orchestration to co-ordinate container deployments at scale. A by-product was the easy abstraction of functions into a ‘serverless’ model, where the service was just there, on demand, in the infrastructure. Now a new layer known as the ‘service mesh’ is coming into being to add governance, management and communication across all of these capabilities. This week saw the release of version 1.0 of a new open source framework for service mesh known as Istio, backed, like Kubernetes before it, by Google, along with IBM.

PostgreSQL and patents

Filed under

OSS

Patents and open-source projects are always a messy combination it seems. A recent discussion on the pgsql-hackers mailing list highlights some of the problems that can result even when a patent holder wants to make their patents available to a project like PostgreSQL. Software patents are a minefield in many ways—often projects want to just avoid the problems entirely by staying completely away from code known to be covered by patents.

It started with a post from Takayuki Tsunakawa, who wondered how his employer, Fujitsu, could submit patches to PostgreSQL that implement various patented (and patent applied-for) techniques: "we'd like to offer our company's patents and patent applications license to the PostgreSQL community free of charge". He suggested three possibilities for how that might be accomplished: by way of a patent pool such as the one run by the Open Invention Network, doing an explicit patent grant (such as that in section 3 in the Apache v2 license), or by a patent promise like Red Hat's, but only for PostgreSQL.

  • Istio v1.0 Service Mesh Released with Features “Ready for Production Use”

    At the Google Cloud Next 2018 event, held in San Francisco last week, the release schedule of the Istio v1.0 service mesh was announced. This week has seen the formal v1.0 release of the open platform that aims to make it easy to "create a network of deployed services with load balancing, service-to-service authentication, monitoring, and more, without any changes in service code". Key new features include cross-cluster mesh support, fine-grained traffic flow control, and the ability to incrementally roll out mutual TLS across a mesh.

  • Google, IBM, RedHat and others launch Istio 1.0 service mesh for microservices

    Istio, an open-source platform that connects, manages and secures microservices announced its version 1.0. Istio provides service mesh for microservices from Google, IBM, Lyft, Red Hat, and other collaborators from the open-source community.

  • Red Hat Releases Istio 1.0 – Already in Use by HP and eBay

    Google Cloud already offering a managed Istio service

    It has been in development for two years and has already been seen in the wild, but this week Version 1.0 of Red Hat’s “Istio” was officially launched.

    Istio is an open source microservices management tool, designed to handle load balancing, flow control, routing and the essential security needs of businesses that use microservices. It can handle service identity and security, policy enforcement and telemetry across apps running on multiple Kubernetes hosts.

  • Google releases universal plumbing for containers

    Google today released version 1.0 of Istio, a “service mesh” designed to make it easier to adopt containers and microservices.

    Istio does so by offering a layer that does jobs like collecting logs, traces and telemetry, authentication and network policy. Any application needs those services and monolithic applications often include them.

    But microservices are designed to orchestrate lots of small single-purpose code chunks into useful applications. It would be wasteful and/or super-complex to build those services into each component of a microservice and doing so would not reduce complexity.

    Enter Istio, which offers itself as the layer to do all the plumbing, regardless of the function or code used in a microservice.

The Search for a GUI Docker

Filed under
Server

I love Docker. At first it seemed a bit silly to me for a small-scale implementation like my home setup, but after learning how to use it, I fell in love. The standard features are certainly beneficial. It's great not worrying that one application's dependencies will step on or conflict with another's. But most applications are good about playing well with others, and package management systems keep things in order. So why do I docker run instead of apt-get install? Individualized system settings.

With Docker, I can have three of the same apps running side by side. They even can use the same port (internally) and not conflict. My torrent client can live inside a forced-VPN network, and I don't need to worry that it will somehow "leak" my personal IP data. Heck, I can run apps that work only on CentOS inside my Ubuntu Docker server, and it just works! In short, Docker is amazing.

I just wish I could remember all the commands.

Don't get me wrong, I'm familiar with Docker. I use it for most of my server needs. It's my first go-to when testing a new app. Heck, I taught an entire course on Docker for CBT Nuggets (my day job). The problem is, Docker works so well, I rarely need to interact with it. So, my FIFO buffer fills up, and I forget the simple command-line options to make Docker work. Also, because I like charts and graphs, I decided to install a Docker GUI. It was a bit of an adventure, so I thought I'd share the ins and outs of my experience.

​Container adoption speeds up to the detriment of VMs

Filed under
Server

Ever since Docker arrived to make containers popular, companies have turned to containers. The inevitable result was virtual machines (VMs) began to decline.

According to Diamanti, a bare-metal container company in its 2018 Container Adoption Benchmark survey of 576 IT leaders, enterprises are using containers to save money by reducing their reliance on commercial virtualization technologies such as VMware's VM. The report examines the current state of container adoption, evaluates container "stack" technology choices, examines containers' impact on VM infrastructure, and finds high levels of enterprise dissatisfaction with VM licensing fees.

  • IBM & Google Launch 'Istio' Cloud Software, but Amazon & Microsoft Skip the Party

    Istio, an open source project backed by IBM, Google, Red Hat and others for connecting, managing and securing Kubernetes containers, hits version 1.0 Tuesday. But can Istio become ubiquitous without support from market leaders Amazon Web Services and Microsoft?

    Istio, also backed by Lyft Inc. and Pivotal , is a "service mesh," picking up where Kubernetes leaves off. Kubernetes provides orchestration to run multiple containers, manage their lifecycle, keep them available and scale them up and down as needed. Istio is software for managing how containers interact with each other.

  • The Istio service mesh hits version 1.0
  • What is Istio? The latest open source project out of Google
  • Istio sets sail as Red Hat renovates OpenShift container ship

    Red Hat is celebrating the 1.0 release of Istio, the open source microservices management project, and the arrival of version 3.10 of its OpenShift software container platform.

    Istio's 1.0 release received mention at Google Cloud Next last week, but the official bits are expected on Tuesday. 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.

  • IBM, Google, Red Hat push Istio to 1.0 release

    IBM launched Istio along with Google Cloud and Lyft a little more than a year ago. The goal of Istio is to give developers a vendor-neutral way to connect, secure and manage networks of various microservices.

    Managing microservices is a critical issue since enterprises are increasingly built on them. By breaking services and applications into smaller parts developers can be more agile. The issue is that managing various microservices requires a good bit of choreography.

The Dark Side of Containers: Protecting Container Data from Itself

Filed under

Containers are virtualized but not by hypervisors. They can be deployed to a VM but are not VMs.

Both containers and VMs use server/host OS as the bottom two layers of the stack. In VM environments, the next level is the hypervisor followed by VMs containing guest OS, libraries (div/lib in Linux), and applications. A single VM runs two full operating systems: the host and guest OS.

In contrast, containers do not have a hypervisor layer. A container shares the host OS, housing only the libraries and application code and data. Container benefits include greater portability, less operational overhead, lower OS licensing and maintenance/support costs, and less expensive application development.
