On my way back I had two paperbacks that was purchased while I was in Austin attending the KubeCon 2017. Kubernetes Up & Running by Kelsey Hightower, Brendon Burns and Joe Beda - this is a special book as I managed to get their Autograph (got two copies one was sent to Colombo office with few other books). Started reading the book after I got on to the plane from LA and managed to finished reading with about 2hrs to land in Australia (in between I watched two movies too ;-) ) Yes I still need to try out many of the examples and possibly building a Pi Cluster in the summer. What did I like about the book? It was an easy read, I was surprised as to how Kelsey, Brendon and Joe managed to keep this book highly technical yet very easy to read and understand. The book covers the most of the key areas related to Kubernetes with detailed examples where possible. They didn't start the book jumping straight into Kubernetes, they had two chapters where they covered on...

Recently started listening to GCP Podcasts by  Mark  and  Francesc . Doing a great job keeping us informed with GCP services plus great interviews with some of the Google and non Google engineers, developers etc. Great Podcasts and happy to recommend.

It is nearly two years since I started writing about Docker, CoreOS (product CoreOS is now known as Container Linux) and Kubernetes. Wow, what I can say things have gone crazy mad. Both Docker and CoreOS having securing funding last year have made major inroads in to communities and enterprises around the world.  That said Kubernetes is one that is not a company has had the most attention in the last twelve months.  For obvious reasons Google was the first to put their public cloud support for Kubernetes, followed by Microsoft Azure and now I am hearing AWS is planning to do similar level of support (although nothing official from AWS yet). Hopefully something might come out of them as well. While both Docker and CoreOS are growing their business and keep contributing to the community some of the key achievements in the last 12 months were the announcements of donating runC, containerD, rkt etc to the Cloud Native Computing Foundation ( https:...

Google Cloud makes Container Builder in General Availability. With Google Cloud Container Builder: You willl get 120 free build mins each day (extra minutes at US$0.0034 at the time of writing) Build with any language and packed in to Docker containers Automate with CI/CD via API Deploy your container to App Engine, Container OR Compute Engines Pull base images from DockerHub, other public repos or your own Google Cloud Registry Build from Google Source repo or GitHub, BitBucket via RepoSync Tag and automate trigger to make a build via Google Source repo, GitHub or BitBucket This gives you the opportunity to stop worrying about having to maintain build servers, manage and monitor them. 

Since I blogged last time the three hot cloud projects have gotten hotter. Docker (docker.com) They have gone from beta container project to creating full orchestration stack with plenty of money in the bank. Unfortunately creating the full orchestration stack had upset CoreOS folks. Docker Machine, Swarm and Compose comprises of the full orchestration stack. While they are still in pre-beta things are very hot and everyone is talking about Docker and nothing else.  Unfortunately I am going to miss the DockerCon in June this year, however looking forward for the next one. CoreOS (coreos.com) They too had a fantastic run so far, with  US $35m funding from none other than Google Ventures for Tectonic  for making Kubernetes for Enterprises. Since last time they too have created multiple stacks supporting containers. Kubernetes (kubernetes.io) One of the leading container cluster management platform with lots and lots of support from open source community as well as big...

You can read the full article written by Joe Fernandes at - OpenShift blog  on why RedHat chose not to join CloudFoundry Foundation. My Comments (given the original blog post is closed for comments, I decided to write my own comments). I have no issues with RedHat not joining CloudFoundry. It is their freedom of choice as to which foundations they join. However I was slightly disappointed in some of the comments/notes by the writer. Of course one could argue, that it is the freedom to write what you like :-).  " Cloud Foundry commercial vendors like Pivotal and IBM should recognize that the path to enterprise success is on Red Hat Enterprise Linux rather than Ubuntu and thus certify Cloud Foundry on Red Hat Enterprise Linux and eventually Red Hat Enterprise Linux Atomic Host." If RedHat was keen to help, shouldn't you join the foundation and get CF certified on RedHat Enterprise Linux, rather than waiting for the vendors such as IBM, Pivotal to come forwa...

There is no doubt that Open Source is leading innovation in Cloud Technologies. However one cannot go without noticing the attention generated for the following three Open Source projects. Interestingly these projects are getting the support from previously not so Open Source friendly companies such as Microsoft. However it is also interesting to hear that Amazon is not jumping on them in a big way yet ???  What are these projects? Docker Going by the definition from Docker website, "Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data cen...
