Kubernetes- making it Highly Available

You can set a Highly Available Kubernetes cluster  by adding worker node pools and master replicas.

That’s true as of Kubernetes version 1.5.2. It is supported using the kube-up/kube-down scripts for GCE (as alpha): http://blog.kubernetes.io/2017/02/highly-available-kubernetes-clusters.html?m=1

For AWS you have support for HA Kubernetes cluster using KOPS scripts:

GCP Big Table – main facts

GCP Big Table – main facts:

Is the basis of many google products
Object storage system

Does not offer indexes except for a single range index you can use

Is the basis for Hadoop big data system

You pay for storage separately

You pay for min 3 nodes and can expand as you need

Nodes are needed just for read / write – not for storage

Support for massive amounts of reads / writes but not locking or transaction support

Is not completely and highly available since sometimes data is not available as it is moved around

Great for big queries, less for short quick rapid ones

Why managers are pushed away by Talents and Leaders

Here are the main points in this brilliant session by Ade McCormack on the new age of workplace, employment and skills

Managers were needed in the Industrial Age to keep an eye on employees that did not like the automatic tasks they had to do
Now automation took over those jobs

There is no room for laziness

The need is for talented people and leaders

Those are passionate people who are eager to do much more than any manager could demand

Talents look for innovation, mobility/flexibility/fun-ability , work/life balance, playing with other great people – all those so much worthy than money, yet so hard to create

When you create a great workplace, great people will join, driving great customers to you as they provide massive value

Nowadays risk is hooked to value

You have to bring risk into your work plans to make real progress

As you play in risky arenas you need some peripheral sensory – data about new risks

You need to spend time trying out the new risk related technologies even if there is no guarantee they will materialize into actual danger

Leaders must make sure their teams don’t have any interference to gain and maintain a state of “flow” – joyful focus on exercising their maximum abilities

Treat your career as a lean startup – choose what you are passionate about, have great skills at, and got market demand for

Ask yourself everyday- am I working in a place that allows me to gain my maximum market value

How hard do you practice and learn to become world class in your arena?
