Redis (REmote DIctionary Server) is the data storage in random access memory that may be also used as a database, caching system, or message broker. Redis is different from relational database in the absence of clear table structures. Values are stored in the ‘key-value’ mode.
The Redis’ main rival is Memcached. In order to start working, it is essential to set the system locally, or to resort to a hosting provider.
Redis supports various data types, particularly strings, hashes, lists, sets, and sorted sets. Mainly, this technology is frequently used for development of mobile applications, games, advertising platforms, financial services, which is entailed by its speed and simplicity. Moreover, applications that operate in real time mode using Redis can fulfil millions of requests a second. Besides, a simplified code writing is among the key advantages since it enables writing less strings for data usage or storage. Apart from that, there are such pluses as transactions (several commands may be performed within one step) and package command processing.
Any system, when used skillfully, will bring much benefit. Redis is not an exception being a convenient, quick and easy-to-study tool that may become a perfect variant for applications oriented towards a fast change of data set.
Anyone who had an experience in the web-development sphere undoubtedly encountered the term REST (Representational State Transfer). This is the architecture style, or the approach to network protocols architecture aimed at providing access to information resources. REST is easier to use, that is why it has completely replaced WSDL (information exchange protocol) and SOAP (data access protocol).
In this way, the key abstraction of ‘representational state transfer’ is the resource which has to be unique. REST has some limitations, or in other words, principles, which are as follows:
- the state absence, that is information about operation state is not stored. Various received requests from one client should not have an influence onto the other one;
- the client-server model, which means division of system according to clients and servers;
- cache, that is there should be information about each element in relation to the possibility of their caching with an aim of productivity increase;
- a homogenous interface that enables an easy component changing if necessary;
- a multi-level system that refers to a limited behavior of components, each of which may observe only the adjacent component;
- the code upon request, i.e. a client can extend functionality when downloading the code (a script or applet form), if necessary.
REST characteristics incorporate such advantages as a better productivity, scaling, easiness in integration with the other websites, convenience of usage, simplicity of making changes, and reliability. Nowadays it is one of the most popular web services due to its flexible architecture. Therefore, this provides development of easy web and mobile applications.
A comfortable and effective option for Drupal/Wordpress developers and purchasers is Pantheon hosting, which is free of charge to use by both during the development stage.
For programmers, the testing server may become the background for a preliminary check of a personal code before transferring the changes to the main one. In return, a purchaser will get a quality and tested product.
Generally speaking, Pantheon divides the project into three parts – a code, a database, and files. The code incorporates CMS files, for example, kernel, themes, Wordpress plug-ins. Files mean the website images. It is essential to mention the importance of Terminus Pantheon utility programme that enables controlling a personal hosting in Pantheon, working with its repositories, etc.
Hosting is quite easy to study with intuitively understandable interface, which is significant, especially for novices. Platform design is remarkable for its ergonomics. From the very beginning, its graphic framework was created for Elementary OS (Linux distribution kit, based on Ubuntu), oriented on macOS, however, with certain differences. Framework may also be installed in the other distribution kits such as Fedora, Manjaroetc. Nonetheless, only in Elementary its highest stability will be provided.
The platform has a range of peculiarities which provide an efficient work of developers, namely cloud integration tools, coaching opportunities, and smooth scanning.
An easy-to-use and convenient platform will provide a quick operation, and an opportunity to expand the working environment just in a few clicks, in particular.
CDN (Content Delivery Network) usage entails the downloading speed increase in terms of various content types (video, audio, images, etc.). This is a so-called network of servers located in different parts of the world that enable the users to get the web site content.
CDN functioning is as follows:
- content uploading into the CDN network;
- content transferring among local servers;
- content obtaining by a user from the nearest server.
Network infrastructure is supported by numerous popular CMS (Drupal, Magento, Joomla, Wordpress, OpenCart etc.). Content Delivery Network usage contributes not only to page loading increase, but it is also advantageous in terms of:
- reduction of the main website servers load due to content caching and, therefore, reduction of the number of server accesses;
- an additional protection from DDos-attacks;
- a positive effect on website ranking in the search systems;
- the website becomes resistant to hyper-activity.
First of all, it is recommended to enable CDN if the target audience are located far from the company servers (in other countries or on the different continents), and for those who have a large volume of files. However, when choosing the content delivery network, it is essential to take into account certain factors, as for the region of server location, pricing and caching policies, and the number of points of presence.
Regardless of the type of resource you own, be it the news portal or the online store, CDN enabling would be worth taking into consideration since it is extremely advantageous for any project.
Solr is the search server realized on Java and founded on Apache Lucene. In other words, this is the technology of search and indexing. Among its key advantages, there are the opportunity of Solr expanding as a separate component, replication, and the opportunity of scaling in accordance with content volume called sharding.
Solr may be effectively used for corporate applications due to certain functions and opportunities, namely:
- administration and configuration support;
- the opportunity of connections between clients and languages.
There are some other, not less important opportunities, as for:
- configuration and adaptation simplicity according to your needs;
- easiness of content indexing as for Microsoft Word, PDF etc. due to embedded Apache Tika;
- understandability of HTML-interfaces;
- server statistics for JMX monitoring;
- result highlighting.
Solr-based applications are much more efficient since this system is created for searching for considerable volume of text-oriented data. Solr provides simplifying in realization of certain tasks. Moreover, it is an effective and competitive search server supplemented with new functions which will undoubtedly be utilzed in further corporate decisions.
Flexibility of data aggregation has entailed the popularity growth of GraphQL usage in recent years. This technology has been applied by numerous famous companies like Facebook, Twitter, Github etc.
GraphQL is referred to as data query language responsible for data processing and databases. In most cases, it is used by a client with an aim of data downloading from a server.
The key features of GraphQL are as follows:
- the possibility to indicate specific data necessary for a client;
- a simplified data aggregation from several sources;
- a type system is used to make data description;
- the possibility of data modification with the help of mutations;
- a much easier query adjustment in comparison with the other query types.
Syntax helps a user place only one call instead of several REST queries to get information.
GraphQL is one of the approaches to API projecting that provides adding new fields and types to the GraphQL API. Besides, older or unnecessary queries and fields may be hidden from API clients.
Among the critical GraphQL patterns there is its hierarchy. This means that data query language is built on object interconnectedness, which simplifies query formation significantly.
In GraphQL, each query level corresponds to a certain type whereas each type describes the available field set.
GraphQL is a powerful instrument, which simplifies developers’ work greatly. They may get certain functions, such as user interface upgrading and caching, with the help of client libraries.
