The main three cloud service models are: IaaS, PaaS and SaaS. Each cloud service model covers different user and company needs, and provides a different level of control, security and scalability. IaaS is the cloud service model that offers a higher level of control compared with an on-premises solution. PaaS makes the process of developing
Cloud computing adoption is an essential step in digital transformation processes, as it enables the modernization of IT infrastructures to leverage further agility, scalability and productivity, among other advantages. The growth potential of the digital economy encourages more and more businesses to shift to new, disruptive technologies and methodologies, and the Cloud is always at
The Internet Protocol version 6 or IPv6 is a version of the Internet Protocol (IP). The Internet Protocol allows the transfer of data through a network to IP addresses (IPv4 or IPv6), which identify the different devices that are connected to the Internet, allowing communications among them. IPv6 should end up replacing IPv4. The transition
How has the Internet changed over the years? The Opte Project, by Barrett Lyon, captures the evolution of the Internet from 1997 to 2021. As the Internet is a network of networks, Barrett Lyon has leveraged the connections among all those networks to create a map of the Internet. This visual representation of the Internet
NoSQL databases are non-relational databases (DBs), intended for applications that need low latency and flexible models to manage large data volumes. They include a wide variety of database technologies designed to meet the development needs of modern applications — which are constantly generating huge amounts of new data. The migration from relational to non-relational databases
Edge computing is a distributed computing architecture, key for those applications that need a really low latency, such as: self-driving cars, real-time image recognition or Augmented Reality (AR). This new paradigm originates in Content Distribution Networks (CDNs), created in the late 1990s to place content closer to end users as the Internet continued to grow
SHA-1 cryptographic algorithm has reached its end of useful life, after 27 years since its publication. The National Institute of Standards and Technology (NIST) recommends replacing it for newer, more secure algorithms like SHA-2 and SHA-3. It aims for the SHA-1 hash function to be completely phased out by the end of 2030. SHA-1 cryptographic
