In this short educational tutorial, we will start by discussing the Ansible Inventory that is used to hold the Ansible Managed Host. We will then discusses the different types of inventories, static and dynamic. Along with different ways, you can apply variables to host in the inventory.

In this tutorial, we are going to discuss Ansible Automation. In particular, Ansible Engine is run from the CLI. We will start by discussing the challenging landscape that is forcing us to move to automation. While introducing Ansible playbooks and the other Ansible main components.

In this video tutorial, we are going through the basics of how monitoring systems work, in particular the role of Prometheus and its pull approach, along with the different types of metrics that Prometheus can scrap.

We generally have two types of telemetry data. We have log data and time-series statistics. The time-series data is also known as metrics. In the context of a microservices environment. The metrics, for example, will allow you to get an aggregate understanding of what’s happening to all instances of a given service. Then we have logs, on the other hand, that provide extremely fine-grained detail on a given service. But have no built-in way to provide that detail in the context of a request.

Due to the nature of how distributed systems fail, you can't use metrics and logs to discover and address all of your problems. We need a third piece to the puzzle and this is distributed tracing.

In the past, the application stack had very few components, maybe just a cache, web server, and database. The most common network service simply allows a source to reach an application endpoint or load balance to a number of endpoints using a load balancing algorithm. The sole purpose of the network was to provide endpoint reachability.

Changes inside the data center are driving networks and network services towards becoming more integrated with the application. Nowadays, the network function exists no longer solely to satisfy endpoint reachability; it is fully integrated and in the case of Red Hat's Openshift the network is represented as a Software-Defined Networking (SDN) layer.

So the most important feature of any system is reliability, and it's not a feature that a vendor can sell you. So if someone tries to sell you an add-on solution called Reliability, don’t buy it, especially if they offer you 100% reliability. In this video, we will discuss the importance of distributed systems and the need to fully understand them with practices like Chaos Engineering and Site Reliability Engineering (SRE). We will also discuss the issues with monitoring and static thresholds.

We will start by discussing how our approach to monitoring needs to adapt to the current megatrends, such as the rise of microservices. Failures are unknown and unpredictable. Therefore a pre-defined monitoring dashboard will have a hard time keeping up with the rate of change and unknown failure modes. For this, we should look to have the practice of observability for software and monitoring for infrastructure.

Containers in non-OpenShift environments have some pretty big security concerns when left to their defaults. In this video, we will go through what some of the host security issues are and how OpenShift overcomes them with Security Context Constraints.

In this video, we will go through some basics of containers. The building blocks of containers are namespaces and control groups. However, they share the host kernel which is a security concern. We will also address container orchestrators with Kubernetes and discuss PODs, Services, NAT, and VXLAN.

This educational tutorial will start with guidance on how the application has changed from the monolithic style to the microservices-based approach along with how this has affected failures. I will introduce to you how this can be solved by knowing exactly how your application and infrastructure perform under stress and what are their breaking points.
