Cloud Computing

 

What is cloud computing?

Cloud computing is the delivery of services including servers, storage, databases, networking, software, analytics, and intelligence over the Internet to offer faster innovation, flexible resources.

Cloud computing technology gives access to storage, files, software, and servers through their internet-connected devices likes computers, smartphones, tablets, and wearables. Cloud computing providers store and process data in a location that’s separate from end users.

Benefits of cloud computing

  • Agility
  • Elasticity
  • Cost savings
  • Deploy globally in minutes


How does cloud computing work?

One benefit of using cloud-computing services is that firms can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure, and instead simply pay for what they use, when they use it.


Cloud computing components

  • Data centers
  • Networking capabilities
  • Virtualization


Types of cloud Services

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)

Your cloud infrastructure can be organized in several ways

  • Public Cloud
  • Private Cloud
  • Community Cloud
  • Hybrid Clouds

What are the advantages and disadvantages of cloud computing?

Cloud computing is not necessarily cheaper than other forms of computing, just as renting is not always cheaper than buying in the long term. If an application has a regular and predictable requirement for computing services it may be more economical to provide that service in-house.

SaaS application may also mean you are using the same applications as a rival, which might make it hard to create any competitive advantage if that application is core to your business.

5G Technology

5G Technology What is 5G? 5G is the fifth generation of cellular technology. It is designed to increase speed, reduce latency, and improve flexibility of wireless services. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices. The 5G network will also simplify mobility, with seamless open roaming capabilities between cellular and Wi-Fi access. Mobile users can stay connected as they move between outdoor wireless connections and wireless networks inside buildings without user intervention or the need for users to reauthenticate. 5G technology will introduce advances throughout network architecture. 5G New Radio, the global standard for a more capable 5G wireless air interface, will cover spectrums not used in 4G. New antennas will incorporate technology known as massive MIMO (multiple input, multiple output), which enables mu

What is Cybersecurity?

  Improve network and cyber security with active measures and unique out-of-the-box features exclusive to Intel Hardware Shield, which includes advanced threat protection, application and data protection, and below-the-OS security. Help ensure your OS boots securely and launch your PCs in a trusted state with Intel Hardware Shield, which prevents malware from compromising the OS and offers hardware-based security capabilities that support a secure startup. An ideal cybersecurity approach should have multiple layers of protection across any potential access point or attack surface. This includes a protective layer for data, software, hardware and connected networks. In addition, all employees within an organization who have access to any of these endpoints should be trained on the proper compliance and security processes. Organizations also use tools such as unified threat management systems as another layer of protection against threats. These tools can detect, isolate and remediate po

Client-Side Technologies

  Client-Side Technologies Client Side Technologies are the tools and languages that run in the user's web browser, rather than on a web server. In the world of web development, client-side technologies handle: Web page layout Form input validation User interaction Dynamic changes in web page content HTML HTML is the standard markup language used to create web pages and web applications. Its elements form the building blocks of pages, representing formatted text, images, form inputs, and other structures. When a browser makes a request to a URL, whether fetching a page or an application, the first thing that is returned is an HTML document. This HTML document may reference or include additional information about its look and layout in the form of CSS, or behavior in the form of JavaScript. CSS CSS (Cascading Style Sheets) is used to control the look and layout of HTML elements. CSS styles can be applied directly to an HTML element, defined separately on the same page, or defined in
