    How does a non-tech person describe DevOps?

    How does a non-tech person explain DevOps? Why do we necessarily need DevOps, how does it boost our business’ productivity and incomes and which are the main DevOps tools in use?1. I’m not a tech expert, explain DevOps to me? A tool? An approach? A role? Few questions in the world have such a diverse of answers, and “What is DevOps?” is one of them. Let’s finally answer this question and find out why adopting DevOps will lead to faster product delivery and higher quality. Why look for the DevOps approach and what are the benefits of integrating it into the software development process? Does any Business need a DevOps approach? How do we manage to achieve the flexibility and operational efficiency of the business infrastructure, being minimal costs served by a solid dose of professionalism, responsiveness and active collaboration? Let's dive into some explanations and divide DevOps into three levels of abstraction: DevOps as a philosophy, as a set of practices, and using the right tools.

  • High availability (Multi-master) Kubernetes cluster hosted on AWS

    High availability (Multi-master) Kubernetes cluster hosted on AWS

        This is a first post of a mini-series dedicated to running Kubernetes hosted on AWS. First post will be about the considerations we have made when proposing production ready and Enterprise grade Kubernetes environment to our clients. I will go more technical, with the tools and AWS services we are using, in the next blog post, here I will try to cover what problems we are solving.     High availability is a characteristic we want our system to have. We aim to ensure an agreed level of operational performance (uptime) for a higher than normal period. These are the principles we follow when doing the system design:  - Elimination of single points of failure. This means adding redundancy to the system so that failure of a component does not mean failure of the entire system.  - Reliable crossover. In redundant systems, the crossover point itself tends to become a single point of failure. Reliable systems must provide for reliable crossover.  - Detection of failures as they occur. If the two principles above are observed, then a user may never see a failure. But the maintenance activity must.        Below graph shows the Kubernetes Master components used for setting up a cluster. Will go thorough them one by one :
