What is Neural Networks?

An artificial neural network learning algorithm, or neural network, or just neural net, is a computational learning system that uses a network of functions to understand and translate a data input of one form into the desired output, usually in another form. The concept of the artificial neural network was inspired by human biology and the way neurons of the human brain function together to understand inputs from human senses.

Neural networks are just one of many tools and approaches used in machine learning algorithms. …

Let’s say you are running a e-commerce. You want to send set of emails to your customer, seller, logistic partner and your employees for every order processing. Order service have to send message to the all the email services but if somehow email service goes down the entire business goes down due on one end customers are purchasing but the messages to the email service get lost every time. So overcome this issue there is a concept message queue let’ look at what is this

Message Queue

What this means is that managing, designing, deploying and testing infrastructure should be done in an analogous fashion to how we do these same things with software. The code that builds, deploys and tests our infrastructure should be committed to source-control in the same way as the code that builds, deploys and tests our software.

What is DevOps?

DevOps is a set of practices that works to automate and integrate the processes between software development and IT teams, so they can build, test and release software faster and more reliably. …

For creating this kind of topology first we have to see some concept of networking related to the routing table that one system can only packet for those systems whose network name is mentioned inside the there routing table. In this setup, this approach is used here

System A

Now first we are giving IP to system A that is 192.168.0.1 with prefix length 24. Using the command:

ifconfig enp0s3 192.168.0.1/24

What is Kubernetes?

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

Why you need Kubernetes and what it can do?

Kubernetes provides you with a framework to run distributed systems resiliently. It takes care of scaling and failover for your application, provides deployment patterns, and more.

Kubernetes provides you with:

• Service discovery and load balancing Kubernetes can expose a container using the DNS name or using their own IP address. …

By default, the restarted argument in the service module is not idempotent so whenever any change occurs or not occurs it always executes which is extra process consumes RAM and CPU.

So to make it idempotent there is a keyword called handlers and notify in Ansible which helps to make it idempotent.

What is Ansible?

Ansible is a software tool that provides simple but powerful automation for cross-platform computer support. It is primarily intended for IT professionals, who use it for application deployment, updates on workstations and servers, cloud provisioning, configuration management, intra-service orchestration, and nearly anything a systems administrator does on a weekly or daily basis. Ansible doesn’t depend on agent software and has no additional security infrastructure, so it’s easy to deploy.

Why use Ansible?

Ansible is generally used for configuration management. …
