Microsoft Azure: Regions and Availability Zones

Before running a VM or any other service inside Microsoft Azure, just a look where the servers can be placed:
This looks fairly the same as the regions at AWS.
Here a better view to europe:

 Each region has several availibility zones (same wording like AWS):
The definition give at Microsoft Azure:

Regions

A region is a set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.

Microsoft Azure: First steps (create an account and logging in)

Oracle OpenWorld Europe : London 2019

Some eleven thousand people descended on Oracle OpenWorld Europe in London last week for two days of business and technical sessions delivered by a mixture of members of Oracle’s product team and end users giving real-world case studies of adoption of Oracle’s Cloud offerings and product roadmaps.

Screen-Shot-2019-01-22-at-13.16.24

Something that may not surprise anyone is that at OpenWorld, to speak of anything other than Cloud or Autonomous would be somewhat blasphemous.

It’s a shrewd move this (more...)

On-Premise Machine Learning with XGBoost (Katana 19.1)

Happy to announce Katana 19.1 release with complete on-premise support for Machine Learning.



You can run Machine Learning (ML) models on Cloud (Amazon SageMaker, Google Cloud Machine Learning, etc.). I believe it is important to understand how to run Machine Learning in your own environment too. Without this knowledge ML skills set would not be complete. There are multiple reasons for this. Not everyone is using Cloud and you must provide on-premise solution. (more...)

A Cloud Endorsement

As I write this, it's super early on Monday morning in my part of the world.  And this morning, I've already spoken to three different customers suffering major service disruptions in their IT applications - one can't process incoming orders, one can't ship product, and another one can't do either (among other things).  The only things still running - their cloud applications.

This raises a pretty good point for those of you out there plugging (more...)

AWS: Accessing S3 buckets from the internet and from ec2 instances

After reading about endpoints for AWS S3 i was wondering how i can use this feature.

First step was to create a bucket and just tried to access this bucket over the internet:

AWS: IAM & security – Best practices: Using a non-root user

After my successful solutions architect practice i knew that i had to take care of my shortcomings in security.
So i decided to visit the IAM (Identity and Access Managemen) of AWS:

  • Delete your root access keys
    I created them for using aws cli (installation or creating a static webpage)
  • Activate MFA on your root account
    No - i will not use multi factor authentication for my playground.
  • Create individual IAM users

AWS: What services are free of charge? How to control your costs…(part 3)

After looking into my bill (see post 1 and post 2) i was keen, how fine granular the cost statistics are inside the aws web console. So i moved to the billing dashboard and to the cost explorer:
This provides you with the following dashboard:
You can play around with the settings to get for example something like this:




AWS Billing: Set an alarm to a cost threshold

Knowing about some details about the costs inside aws and some of the services (especially, that Docker, VPNs and Kubernetes are not included in the free trials)

i set an alarm on my account, to get informed about new costs:

So move to "Cloudwatch" and there you have to choose "Alarms":

 Then "Create Alarm":

Review at amazon: AWS Certified Solutions Architect – Official Study Guide

This weekend i read this book:

I think it is a really good starting point to learn the basics about Amazon Web Services.
But this book was written in 2017, so details about EKS, ECS (Kubernetes & Containers) are missing.

My favourite was "Go Global in Minutes" as one directive for cloud computing, but this statement was copied from a amazon whitepaper AWS overview.



If you are interested, take a look at my review (more...)

There is a nice tutorial how to create a static webpage with using Amazon S3:
https://docs.aws.amazon.com/AmazonS3/latest/dev/HostingWebsiteOnS3Setup.html

I will try to create such a website via aws cli - so that this can be automated:
