Cloud servers are virtual servers that, just as traditional servers, deliver processing power and data storage. However, they are virtualized, delivered over a public or private network, using IPv4 or IPv6, and accessed remotely. How does a cloud server work? Cloud servers are virtualized using a hypervisor like VMware or Openstack. The hypervisor acts as
Internet Exchange Points or IXPs are a key element of the functioning of the Internet. The Internet has become an essential tool for many people. Thousands of millions of people use it every day for checking their email, visiting their favorite websites and purchasing in eCommerce sites. Many people know how to use the network
In this post we want to collect the most common terms in cloud computing; from basic concepts such as the main cloud service models and types of cloud to more specialized concepts related to cloud computing. Let’s start from the beginning… What is cloud computing? Cloud computing is a computing resources and services distribution model
Performance tests help measure diverse aspects of web applications, sites and environments, in order to guarantee they are fast, stable and scalable. There are diverse types of performance tests, such as load tests, stress tests or capacity tests. What is a performance test? Performance tests are used to measure stability, scalability, throughput and performance of
Network latency, or simply latency, is the time it takes to transfer a packet between a server and a user through a network. It is one of the factors that determine network performance. The shorter the delay to transfer data across a network, the lower the latency and vice versa. The lower, the better: why
A bare-metal server is a physical server with a single tenant. That is to say, a physical server of exclusive use of the client who rents it, which is not shared with other organizations or users. Together with virtual servers, networking and storage, bare-metal servers are an essential part of the IaaS cloud service model.
There are numerous submarine cables in the Iberian Peninsula that connect it with all regions around the world — Africa, Asia, North America, South America, Oceania and the rest of Europe. In fact, there are almost 40 submarine cables with landing points in Portugal and Spain. The need for new undersea cables increases as international
As private cloud solutions continue to gain in popularity, the question “on-premise vs hosted private cloud” arises. Companies are looking into the private cloud as an infrastructure solution that offers a balance between the functionalities and scalability of cloud services and the security, control and robustness of traditional IT infrastructures. Both deployment models have points
In IT, a Security Operations Center (SOC) or Information Security Operations Center (ISOC) is a centralized location where an organization’s security team monitors, analyzes, detects and solves any cybersecurity events that might arise. However, in addition to this definition, a SOC can also refer to an in-house team of cybersecurity professionals or an outsourced SOC
In computing, stress testing is a type of performance test used to determine the stability and reliability of systems and applications. Also known as “endurance testing” or “torture testing”, it is particularly recommended for mission critical systems and infrastructures. Stress tests Stress tests push hardware and software capabilities beyond normal operating conditions in order to
