Install Seesaw Ubuntu
“In the era of concurrent execution, there have been running many processes simultaneously to make more throughput and high working efficiency. In such circumstances, the servers are required to handle loads of workload for high performance, and it gets difficult for the servers to manage such huge traffic. To rescue this devastating situation, load balancers come to rescue the servers. These load balancers distribute the workload between the several networks and the hosts (that are being clustered) to increase the availability, performance, and reliability of the networks. Load balancers take the incoming network requests and assign them a VIP (Virtual IP address) and then send these requests to that server which load balancer finds an appropriate one keeping the minimum possible packet modification. The selected server by the load balancer then replies to the load balancer with the data being required; the load balancer then passes this required data to the client.”

ImageMagick Sharpen Image
“Editing photographs, changing their formats, renaming images, and doing numerous operations on multiple files at once are frequent tasks. Both vector and raster images can be shown, converted, and edited using the free and open-source software “ImageMagick”. John Cristy created it in 1987 while he was employed by DuPont. He utilized it to create several of his creations and compress 24-bit photos to 8-bit graphics. Once he transferred the ownership to ImageMagick Studio LLC in 1990, it was publicly disclosed. It provides rudimentary API-like capabilities for UNIX-like computers but lacks a full GUI like Adobe Photoshop, Lightroom, and GIMP. Numerous image file types are supported, including GIF, JPEG, PNG, Postscript, and TFF.”

SSL Nginx Web Server
“Nginx, also abbreviated as “Engine-x,” is an open source Linux software that serves as a web server for HTTP caching, reverses proxy, and balancing of load. It proves to be a high-performance web server for its high-performance stability, HTTP capabilities, improved application-based deliveries, and security of the websites with the reduction of the long waiting times for the busiest web pages by acting as a load manager/balancer for the websites. Being a competitive lightweight server, Nginx offers a tremendous variety of features, and one of these features includes “Secure Service Layer (SSL)”. SSL is the technology that enables HTTP websites to secure the connection between the web server and web browser from any malicious attacks from unknown sources.”

Ansible Tutorial for Beginners
“Ansible is an open-source IT engine that optimizes the deployment of IT technologies, including intra-service orchestration, cloud provisioning, as well as application deployment. Because Ansible pushes modules toward clients rather than using any client-side agents or customized security architecture, it is simple to implement. The output of such modules was sent back to that same Ansible server once they had been run locally on that client side.
It can quickly establish SSH-Key connections with clients, streamlining the entire procedure. The files, which are sometimes called inventory folders, include the client data. Ansible may utilize an inventory file that you’ve produced but also filled up.
Ansible employs the playbook that utilizes plain language, i.e., YAML, to specify automation jobs. Although YAML is frequently used only for configuration files, it may be utilized in a wide variety of applications whereby data is already saved. The fact that any of the IT infrastructure support staff can understand and read the playbook but also troubleshoot if necessary is a huge advantage.
