Memcached is a system for caching objects located in RAM. Installing and configuring Memcached is necessary in order to reduce the load on the file system and database, thereby speeding up the work of the entire website. Caching allows you to reduce the number of database requests and, as a result, increase the stability and fault tolerance of your entire network infrastructure. Memcached can store objects of various types, but this technology is most useful in relation to frequently requested data. The same files that are requested once every 2-3 days or less are better stored in the file cache, but here everything depends on the architecture of your project.
OSI is an abbreviation, stands for Open Systems Interconnection model. We are talking about a 7-level open network model, where each level performs certain tasks. This model itself is designed to generalize and standardize the provision of means of network interaction in telecommunications and computer systems. In fact, the concept was developed to solve the problem of compatibility of different devices that differ from each other. Unify their work and bring them to some common standards, even if the communication protocols are different.
During the initial configuration of the server, one of the most important steps is the installation of PHP extensions – they are needed for most CMS, including the popular WordPress, Magento, and Laravel. In this article, we will tell you which PHP scripts must be installed and how to do it through the console. We will install it on Ubuntu 20.04, but the syntax of the commands described below can be adapted to any other Linux system.
Sites manually written in HTML are characterized by increased performance and stability. Of course, provided that an experienced and attentive IT specialist writes the code. Such a site is ideal for placing static and materials in small volumes when it is not supposed to make regular changes to the content. HTML sites do not have a control panel, and web pages are edited manually – this creates certain inconveniences for "dynamic" projects, such as online stores, online service storefronts, news sites, etc.
The era of the free Internet is coming to an end – governments of different countries are gradually establishing control over providers in order to restrict citizens' access to certain sites. When it comes to criminal and immoral content that can really harm society, such restrictions are justified. But in recent years, cases of blocking sites for ridiculous reasons have become more frequent – for example, because the domain belongs to an unfriendly state.
When it comes to Linux, most people immediately recall the famous meme from the cult movie "The Hangover", in which Zach Galifianakis appears surrounded by complex mathematical formulas. As if only the chosen ones were able to master the art of Linux management, and for ordinary mortals, this is something incomprehensible. By "the chosen ones" we mean bearded programmers who are able to sort an array with random numbers using the "bubble" method with one eye, and who are able to count linear algorithms in their minds.
CDN (Content Delivery Network) is a geographically distributed network infrastructure created to optimize the delivery and distribution of data to the end user – you and me.
Hi! HostZealot team would like to introduce you to our new partner Keitaro.io:
You can develop websites in different ways, from manually writing code to collecting ready-made templates using designers. Now almost no one creates handwritten websites, because it is expensive and difficult. At the same time, with the help of designers, you can quickly build a good and stable website that will fully perform its functions. In this article, we will talk about the top five CMS that greatly simplify the creation, editing and management of website content.
Network Address Translation, abbreviated as NAT, is a network address translation mechanism necessary for the full functioning of the Internet formed by unified computer networks under the control of the TCP/IP protocol. The key problem that NAT solves is the shortage of IP addresses, which was predicted back in the 2000s. The IPv4 Internet protocol allows you to create approximately 4.3 billion addresses, and if in the 80s of the last century this was enough, today the figure looks quite ridiculous.
