DevOps Automation
DevOps is an approach to culture, automation, and platform design intended to deliver increased business value and responsiveness through rapid, high-quality service delivery. DevOps practices bring development and operations team members together into a single DevOps team. This moves ideas and projects from development to production faster and more efficiently. DevOps involves more frequent changes to code and more dynamic infrastructure use when compared to traditional, manual management strategies.
Automation
Automation is the use of technology to perform tasks with reduced human assistance. Automation helps you accelerate processes and scale environments, as well as build continuous integration, continuous delivery, and continuous deployment (CI/CD) workflows. There are many kinds of automation, including IT automation, business automation, robotic process automation, industrial automation, artificial intelligence, machine learning, and deep learning.
Provisioning
DevOps environments encompass a variety of technologies. Provisioning and deploying changes to these complex environments can be time-consuming and requires expert knowledge for each component. Applying Infrastructure as Code (IaC) approaches with automation allows IT teams to provide self-service capabilities and deliver preapproved resources and configurations with limited manual intervention.
Java & .Net Applications Development
Software developers require IT resources to create, continually test, and deploy new applications and services. Manual IT operations can delay resources and complicate the service delivery pipeline. It can impede proof-of-concept performance, ultimately resulting in slower development. By combining application programming interface (API)-centric design with automation, IT teams can deliver resources faster while supporting rapid proofs of concept, development, testing (using test automation open source projects like Jenkins), and deployment.

Improves security for Internet of Things (IoT) edge devices
Java Card enables secure elements, such as smart cards and other tamper-resistant security chips, to host applications based on Java technology. Store and update multiple applications on a single, resource-constrained device.
.Net
NET is a free, cross-platform, open source developer platform for building many different types of applications. With . NET, you can use multiple languages, editors, and libraries to build for web, mobile, desktop, games, and IoT.
Net is a programming language developed by Microsoft. It was designed to build applications which could run on the Windows platform. The . Net programming language can be used to develop Forms based applications, Web based applications, and Web services.
. Net comprises both frontend and backend languages. As for example, ASP.NET is used as backend and C# & VB.NET are used for frontend development.
NET Framework (pronounced dot net) is a product of Microsoft. It is a programming framework used by Software applications in order to run. It has two major parts: the Common Language Runtime (CLR) and the . It also greatly simplifies Windows programming.
Cloud Computing
Cloud Computing is the delivery of computing services including servers storage databases, networking, software, analytics, and intelligence over the Internet (the cloud) to offer faster innovation, flexible resources, and economies of scale.
Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Agility
The cloud gives you easy access to a broad range of technologies so that you can innovate faster and build nearly anything that you can imagine. You can quickly spin up resources as you need them from infrastructure services, such as compute, storage, and databases, to Internet of Things, machine learning, data lakes and analytics, and much more.
You can deploy technology services in a matter of minutes, and get from idea to implementation several orders of magnitude faster than before. This gives you the freedom to experiment, test new ideas to differentiate customer experiences, and transform your business.
Elasticity
With cloud computing, you dont have to over-provision resources up front to handle peak levels of business activity in the future. Instead, you provision the amount of resources that you actually need. You can scale these resources up or down to instantly grow and shrink capacity as your business needs change.
Cost savings
The cloud allows you to trade capital expenses (such as data centers and physical servers) for variable expenses, and only pay for IT as you consume it. Plus, the variable expenses are much lower than what you would pay to do it yourself because of the economies of scale.
Deploy globally in minutes
With the cloud, you can expand to new geographic regions and deploy globally in minutes. For example, AWS has infrastructure all over the world, so you can deploy your application in multiple physical locations with just a few clicks. Putting applications in closer proximity to end users reduces latency and improves their experience.
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
Linux Operation Systems
Just like Windows, iOS, and Mac OS, Linux is an operating system. In fact, one of the most popular platforms on the planet, Android, is powered by the Linux operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply, the operating system manages the communication between your software and your hardware. Without the operating system (OS), the software.
Why use Linux?
This is the one question that most people ask. Why bother learning a completely different computing environment, when the operating system that ships with most desktops, laptops, and servers works just fine?
To answer that question, I would pose another question. Does that operating system you?re currently using really work ?just fine?? Or, do you find yourself battling obstacles like viruses, malware, slow downs, crashes, costly repairs, and licensing fees?
If you struggle with the above, Linux might be the perfect platform for you. Linux has evolved into one of the most reliable computer ecosystems on the planet. Combine that reliability with zero cost of entry and you have the perfect solution for a desktop platform.
Thats right, zero cost of entry as in free. You can install Linux on as many computers as you like without paying a cent for software or server licensing.
And dont think the server has been left behind. For this arena, you can turn to:
Red Hat Enterprise Linux
Ubuntu Server
Centos
SUSE Enterprise Linux
