What is cloud computing and how it works?


Cloud computing, in its most basic form, is a collection of services offered via the internet, or "the cloud." It entails storing and accessing data on remote servers rather than local hard drives and private datacenters.

Before cloud computing, businesses had to buy and operate their own servers to satisfy their needs. This necessitated the purchase of sufficient server space to limit the risk of downtime and disruptions while also accommodating peak traffic demand. As a result, vast quantities of server space sat idle for the majority of the time. Cloud service providers today enable businesses to eliminate the need for onsite servers, maintenance workers, and other costly IT resources.

There are three types of cloud computing deployment models:
Private cloud is a private cloud environment for a single business organization, with physical components housed on-premises or at a vendor's datacenter. Because the private cloud is exclusively available to one company, this solution provides a high level of control. Customized architecture, sophisticated security mechanisms, and the capacity to extend computer resources in a virtualized environment as needed are all advantages.

Public cloud uses the internet to store and manage access to data and applications. It’s completely virtualized, providing an environment where shared resources are leveraged as needed.

Hybrid cloud blends private and public cloud models, allowing organizations to reap the benefits of shared resources while maintaining crucial security needs on existing IT infrastructure. Companies can use the hybrid cloud architecture to store sensitive data locally and access it through applications operating in the public cloud.

Furthermore, enterprises might choose for a multi-cloud strategy, in which they use more than one public cloud provider. This method allows organizations to optimize their environments for performance, flexibility, and cost savings by distributing workloads over several cloud platforms.

When was biometrics first used?

Image
In recent years, biometric authentication has entered the mainstream; facial recognition on smartphones, technologies to speed up the airport experience, finger print access to online banking apps, or even biometric payment cards are just a few examples. While it may appear to be a novel notion, biometrics has been around for decades. Biometrics can be traced back to ancient times when fingerprints and handprints were used to sign and seal documents. The application of biometrics as a tool for identification and security purposes began in the late nineteenth century with the work of Alphonse Bertillon.  In 1879, a French police officer established an anthropometry method that involves measuring numerous physical traits such as height, weight, and the size of the head, arms, and feet to identify criminals. This approach was widely utilized by police agencies around the world and was regarded the gold standard for identification until the early twentieth century. In the early 20th centu

How does Cloud Storage work?

Image
Cloud Storage stores data on remote servers, such as files, corporate data, videos, or photographs. Users upload data to servers via an internet connection, where it is saved on a virtual machine on a physical server. To ensure availability and redundancy, cloud companies frequently distribute data to many virtual computers in data centers  situated across the world. If storage requirements increase, the cloud provider will spin up extra virtual computers to handle the strain. Users can access data in Cloud Storage via an internet connection and software such as a web portal, browser, or mobile app via an application programming interface (API). Cloud Storage is available in four different models: Public: Public Cloud Storage is a paradigm in which an organization stores data in the data centers of a service provider that are also used by other businesses. Data in public Cloud Storage is distributed across various areas and is frequently available via subscription or pay-as-you-go. P

Will AI replace hackers?

Image
As artificial intelligence (AI) and machine learning (ML) gain traction in the cybersecurity business, fears about the future of cybersecurity jobs mount. Many people are concerned that AI will eventually replace human cybersecurity specialists; however this is not totally accurate and is based on many fallacies. One of the most common misconceptions about AI is that it can think and learn like a human, but in reality, AI is still constrained by the data on which it is educated. While AI is capable of analyzing enormous volumes of data and identifying patterns, it lacks human intuition, creativity, and decision-making abilities. Because threats and attacks can be complicated and subtle, cybersecurity requires a human touch. Cybersecurity specialists, unlike AI, can think outside the box, employ critical thinking abilities, and devise novel solutions. Furthermore, AI systems may be incapable of detecting novel and emerging risks. Furthermore, AI may be unable to recognize the context o
