Cloud Comparisons (IaaS)

I was currently consulting again at how AWS vs Azure compares on an IaaS level and how this is related to Oracle. Did you know that @azure compares itself to @awscloud and simply put a doc on the @microsoft site? Wouldn’t that be a cool thing to do for lets say Google and the Oracle cloud?

A collection of resources for AWS vs Microsoft:

 

Here is why Microsoft thinks that they are superior. Interesting that they (also) drill on the number of data centers which is simply a head to head race (where Microsoft was indeed leading as of April 2017).

 

Show EC2 Instances across all Regions

A note to myself (might be useful to you as well):

for region in `aws ec2 describe-regions --output text | cut -f3`
do
     echo -e "\nListing Instances in region:'$region'..."
     aws ec2 describe-instances --region $region
done

Oracle CODE Mexico City 2017

A fortnight ago I was travelling to Mexico City / Santa Fe to speak at the Oracle CODE event. It was a huge event, relaxed atmosphere and everybody seemed to have a great time learning new tech. Gossip was spreading that over 2000 people signed up for it.

Myself, I did a live-hacking session, explaining the reasoning from building an ‘artesania’ Docker Swarm cluster to moving to Oracle Container Cloud Service (OCCS) and Wercker. This included a complete CI/CD workflow: based on a simple git commit for a Spring Boot application, building a new Docker image that will be stored on Docker hub, and then pushed to OCCS . Yes, live on stage 🙂 and live in the cloud.

Maybe the biggest impact on my session had the Mexico vs. Germany football match that just ended a few minutes before my presentation. After Mexico not winning 1:4 against GER there were still some 100 people in the mood to attend my live hacking session. Many of those showed up afterwards to say hello and ask advanced questions which was a pleasant surprise!

This is part of the group. Can you spot Mini, the cluster?  🙂

Even after walking out of my session and hanging around in the foyer, I got heaps of questions from people asking me about clustering Docker containers, the reasoning and difficulty of building a Raspberry Pi based Docker cluster, how OCCS differs to all of this and why and how Oracle is involved in Docker.

Have you been there? Something worth to repeat? Share your opinion about the event as a comment.

 

Cloud, Microservices and Container Workshop in South Africa!

Lot’s of people are talking about these topics nowadays. Heaps of slides and samples are available for download, lots of presentations can simply be streamed from youtube.

In Johannesburg we were working with these solutions hands-on: I delivered a 3 day Cloud, Microservices and Containers workshop on behalf of Oracle.

Find attached some impressions from the smart and fun group of devs and architects I was working with.

 

 

User Wercker to Start a Kubernetes Cluster: Click2Kube

When Oracle recently acquired Wercker some people wondered how it will fit into the Oracle cloud portfolio. Now there is a bit more of a clue; Oracle started beta-testing Click2Kube which allows you to to use Wercker to spin up a Kubernetes cluster.

In a quick smoke test I achieved the following in a few minutes:

  • I provisioned a Kubernetes cluster in about 4 minutes.
  • Details about the endpoint in the form https://k8s-master.1234567.obmc.wercker.com was mailed to me
  • The cluster can be accessed using standard kubectl from the command-line. Also an example of how to configure access to the cluster for the endpoint given is provided.

Once more I am packing suitcases, yet I am looking forward to explore it a bit more in depth. Looks like there is exciting stuff ahead! Check out http://www.wercker.com/ for more details.

By the way, I will also be speaking about Wercker and how it works together with OCCS at Oracle CODE in Mexico City on June 29th, 2017. Save the date now, pass by, and say Hola!
