A content delivery network (CDN) is a way to deliver content from your website or mobile application to people more quickly and efficiently, based on their geographic location. A CDN is made up of a network of servers (“points of presence,” or POPs) in locations all over the world. The CDN server closest to a user is known as the “edge server” — when people request content from a website served through a CDN, they’re connected to the closest edge server, ensuring the best online experience possible. Imagine that you’re in San Francisco and you’ve requested an image on a server in London, 5300 miles away. It would typically take around 300 milliseconds to send the request and receive the response. If you were to request the same image from a server in San Jose, which is about 50 miles from San Francisco, it would take about 10 milliseconds to send the request and get the response. That’s 30 times better than the first case but because we’re speaking in terms of milliseconds the difference might be imperceptible.

A database is usually controlled by a database management system (DBMS). Together, the data and the DBMS, along with the applications that are associated with them, are referred to as a database system, often shortened to just database. Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. Most databases use structured query language (SQL) for writing and querying data.

A cloud server is a pooled, centralized server resource that is hosted and delivered over a network—typically the Internet—and accessed on demand by multiple users. Cloud servers can perform all the same functions of a traditional physical server, delivering processing power, storage and applications. Cloud servers can be located anywhere in the world and deliver services remotely through a cloud computing environment. In contrast, traditional dedicated server hardware is typically set up on premises for exclusive use by one organization.

Microsoft Azure, formerly known as Windows Azure, is Microsoft's public cloud computing platform. It provides a range of cloud services, including compute, analytics, storage and networking. Users can pick and choose from these services to develop and scale new applications, or run existing applications in the public cloud.

Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each location being a data center.

A blockchain is “a distributed database that maintains a continuously growing list of ordered records, called blocks.” These blocks “are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. A blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.”

In futurism and science fiction, the metaverse is a hypothetical iteration of the Internet as a single, universal and immersive virtual world that is facilitated by the use of virtual reality (VR) and augmented reality (AR) headsets.

It easily integrates with the different platforms such as Android, IOS and Linux, MAC, Windows and Google Fuchsia applications.

AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of Amazon Web Services. Therefore you don’t need to worry about which AWS resources to launch, or how will you manage them. Instead, you need to put the code on Lambda, and it runs. In AWS Lambda the code is executed based on the response of events in AWS services such as add/delete files in S3 bucket, HTTP request from Amazon API gateway, etc. However, Amazon Lambda can only be used to execute background tasks. AWS Lambda function helps you to focus on your core product and business logic instead of managing operating system (OS) access control, OS patching, right-sizing, provisioning, scaling, etc.

Amazon CloudFront is a content delivery network (CDN) operated by Amazon Web Services. Content delivery networks provide a globally-distributed network of proxy servers that cache content, such as web videos or other bulky media, more locally to consumers, thus improving access speed for downloading the content. CloudFront has servers located in Europe (United Kingdom, Ireland, The Netherlands, Germany, Spain), Asia (Hong Kong, Singapore, Japan, Taiwan and India), Australia, South America, Africa, and several major cities in the United States.

Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key–value and document data structures and is offered by Amazon.com as part of the Amazon Web Services portfolio. DynamoDB exposes a similar data model to and derives its name from Dynamo, but has a different underlying implementation. Dynamo had a multi-leader design requiring the client to resolve version conflicts and DynamoDB uses synchronous replication across multiple data centers for high durability and availability.

ECS is an acronym for “EC2 container service”. In simple terms, it provides a way to deploy your Docker containers over the Amazon platform on an EC2 instance or serverless(FARGATE)! ECS helps you orchestrate your containers and helps your provision your own containers. So if you have any containers running on your local machine but you want to make it live on a public platform to get publically accessible, AWS ECS is the solution for that along with “ECR” and “Task definitions” and “services”.

CPA Stands for "Cost Per Action," and is used in online advertising. CPA defines how much revenue a publisher receives when a user clicks an advertisement on his website and then completes a certain action. For example, a publisher may place a banner or text link from an advertiser on his website. When a user clicks the link, she is directed to the advertiser's website. She might then be asked to fill out a form or take a survey. If she completes the form or survey, the action has been completed, and the advertiser pays the publisher a certain amount based on the CPA.

Cost per mille (CPM), also called cost per thousand (in Latin, French, and Italian, mille means one thousand), is a commonly-used measurement in advertising. It is the cost an advertiser pays for one thousand views or impressions of an advertisement. Radio, television, newspaper, magazine, out-of-home advertising, and online advertising can be purchased on the basis of exposing the ad to one thousand viewers or listeners. It is used in marketing as a benchmarking metric to calculate the relative cost of an advertising campaign or an ad message in a given medium. The "cost per thousand advertising impressions" metric (CPM) is calculated by dividing the cost of an advertising placement by the number of impressions (expressed in thousands) that it generates. CPM is useful for comparing the relative efficiency of various advertising opportunities or media and in evaluating the overall costs of advertising campaigns

An impression is a metric used to quantify the number of digital views or engagements of a piece of content, usually an advertisement, digital post, or a web page. Impressions are also referred to as an "ad view." They are used in online advertising, which often pays on a per-impression basis. Counting impressions is essential to how web advertising is accounted and paid for in search engine marketing, as well as measuring the performance of social media campaigns. Impressions are not a measure of whether an advertisement has been clicked on, but how many times it was displayed or had potential "eyeballs" on it, which leads to some debate as to how accurate the metric is.

Copywriting is one of the most important elements of advertising and marketing. It's the process of writing persuasive words (known as copy) that inspire or motivate people to take a specific action. When you open a magazine and there's a full-page advertisement selling perfume, the words on that page are the result of copywriting. When you go to a website that prompts you to buy something, the words on that page are the result of copywriting. You can find copies in print, online, and even being read on television or over the radio. Copywriting is almost everywhere you look and listen.

An API, or application programming interface, is a set of rules that define how applications or devices can connect to and communicate with each other. A REST API is an API that conforms to the design principles of the REST, or representational state transfer architectural style. For this reason, REST APIs are sometimes referred to RESTful APIs.

ActiveCampaign is a cloud software platform for small-to-mid-sized businesses and is based in Chicago, Illinois. The company offers software for customer experience automation (CXA), which combines the transactional email, email marketing, marketing automation, sales automation, and CRM categories.

The dictionary defines automation as “the technique of making an apparatus, a process, or a system operate automatically.” We define automation as "the creation and application of technology to monitor and control the production and delivery of products and services.” Using our definition, the automation profession includes “everyone involved in the creation and application of technology to monitor and control the production and delivery of products and services”; and the automation professional is “any individual involved in the creation and application of technology to monitor and control the production and delivery of products and services.”

Short for a video blog or video log, a vlog is a blog in video form. Think of it as your own little TV show or channel, only it’s on the web, produced by you, and presumably starring you (or maybe your super cute pet). There are a number of platforms where you can create a vlogging channel and publish video content. The most-viewed and successful vlogs are YouTube channels, but there are other platforms where you can publish like Instagram and Twitch. While the vlog format is video and the publishing medium is the web, the rest is limited only by your imagination. Your vlog can be instructional or performance art, documentary or comedy in style. It can include nothing but video or video plus text, images, and other fun features that help you get your point across and entertain. It can be shot in one take or expertly edited.

A blog post is an individual web page on your website that dives into a particular sub-topic of your blog. Blog posts allow you to rank on search engines for a variety of keywords. In the above example, your blog post could enable your business to rank on Google for "fall shoes". When someone searches for fall shoes and comes across your blog post, they have access to the rest of your company's website. They might click "Products" after they read your post, and take a look at the clothing items your company sells.

E-commerce (electronic commerce) is the buying and selling of goods and services, or the transmitting of funds or data, over an electronic network, primarily the internet. These business transactions occur either as business-to-business (B2B), business-to-consumer (B2C), consumer-to-consumer or consumer-to-business. The terms e-commerce and e-business are often used interchangeably. The term e-tail is also sometimes used in reference to the transactional processes that make up online retail shopping.

Dropshipping is an order fulfillment method where a business doesn’t keep the products it sells in stock. Instead, the seller purchases inventory as needed from a third party—usually a wholesaler or manufacturer—to fulfill orders. The biggest difference between dropshipping and the standard retail model is that the selling merchant doesn’t stock or own inventory—they act as the middleman.

WooCommerce is the most popular and arguably best ecommerce plugin for WordPress, and its integration provides great SEO for ecommerce websites. Because it is open source, it offers limitless customizations. Using WordPress with WooCommerce means you'll have the support of the robust open source community.

Currently, there are 292,051 live websites using OpenCart.

Microsoft Teams is a workspace in Microsoft 365 - formerly known as Office 365. It's integrated with all the Microsoft applications, including traditional Microsoft Office apps like Outlook. Hundreds of thousands of businesses, organisations, schools, colleges and universities are already using it. Teams is intended for people who use Office 365 on a regular basis - if your company or organisation is a Google G Suite (Google Apps) user, then it's really not going to be as appealing and you're probably better off plumping for Google Meet instead.

GitHub or GitHub.com is a cloud source code management service platform designed to enable scalable, efficient, and secure version controlled collaboration by linking local Git version controlled software development by users. GitHub’s main business footprint is hosting a collection of millions of version controlled code repositories.

Mailchimp is a comprehensive email marketing platform that fulfills all your requirements of email correspondence with customers, affiliates, and other stakeholders. Unlike many other all-in-one marketing and automation platforms, Mailchimp is a web-based application. This means you can use it just like a website on any web browser without needing to download and install a heavy software program on your devices.

Search engine optimization is the science of improving a website to increase its visibility when people search for products or services. The more visibility a website has on search engines, the more likely it is that brand captures business. Website visibility is commonly measured by the placement -- or ranking -- of the site on search engine results pages (SERPs). And companies always vie for the first page, where they are most likely to garner the most attention. SEO is Google’s way of determining which sites deserve to rank highly for each query entered into its search engine. Without modern SEO, it would be extremely simple to manipulate the search results so that the site with the most links or the most pages—all easily generated by software—consistently ranked #1.

Multiexperience refers to a user’s whole experience with one application across a variety of digital touchpoints—websites, mobile apps, chatbots, augmented reality/virtual reality, wearables—using a combination of interaction modalities, like touch, voice, vision, and motion. The purpose is to support a seamless and consistent user journey. It is no longer a question for companies of whether to just deploy a web platform or mobile, or both. It’s about working with the growing market of devices and the respective experience of each. Applications must run flawlessly across platforms while building a consistent and engaging connection throughout.

A cloud-native platform refers to the idea and application of building and operating systems that take advantage of the distributed computing offered by the cloud delivery model. Cloud-native applications are designed to be resilient and utilize the elasticity, order, and flexibility of the cloud.

Voice user interface (VUI) is speech recognition technology that allows people to interact with a computer, smartphone or other device through voice commands. Apple's Siri, Amazon's Alexa, Google's Assistant and Microsoft's Cortana are prime examples of VUIs. What makes a VUI unique is that it uses voice as the primary mode of interaction, in contrast with the traditional keyboard-mouse-monitor combination or touch screen. This voice-first approach can allow users to initiate automated services and execute their day-to-day tasks in a faster, more intuitive manner.

Cybersecurity mesh architecture (CSMA) is an architectural approach rather than a specific technology or market segment. It is a similar concept to zero trust. However, while zero trust presupposes that every device in an ecosystem is already compromised and potentially hostile, CSMA sees environments as disparate, logically separated and heterogeneous. That's a simplification, of course, but it's intrinsic and baked in.

Extended reality (XR) is a term referring to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables.[circular reference] E.g. It includes representative forms such as augmented reality (AR), mixed reality (MR) and virtual reality (VR) and the areas interpolated among them. The levels of virtuality range from partially sensory inputs to immersive virtuality, also called VR.

It’s the extension of legacy business process automation beyond the confines of individual processes. By marrying AI tools with RPA, hyperautomation enables automation for virtually any repetitive task executed by business users. It even takes it to the next level and automates the automation - dynamically discovering business processes and creating bots to automate them. Hyperautomation was identified by Gartner as one of the year’s top 10 strategic technology trends.

XaaS is a collective term that refers to the delivery of anything as a service. It encompasses the many products, tools and technologies that vendors deliver to users as a service over a network -- typically, the internet -- as an alternative to providing them locally or on-site to an enterprise. This umbrella term refers to service offerings that are accessed as needed and financed using a pay-as-you-go cloud computing pricing model. XaaS offerings can scale up or down as needed with IT services delivered on demand by a managed service provider.

PaaS is a type of cloud computing that "allows customers to provision, instantiate, run, and manage a modular bundle comprising a computing platform and one or more applications, without the complexity of building and maintaining the infrastructure typically associated with developing and launching the application(s); and to allow developers to create, develop, and package such software bundles." Basically, infrastructure is provided over the internet that allows you to build and maintain applications for yourself or whatever company you are designing the application for

A quantum computer is a machine that harnesses some of the unique properties of quantum physics to solve problems that are too complex for regular computers and even supercomputers. The field of quantum computing focuses on developing technology that takes advantage of the ways in which energy and matter behave at the subatomic level. We use the word ‘quantum’ to describe the laws of physics that apply at the level of individual atoms, electrons and elementary particles. At this microscopic level, the laws of physics are different from those we experience in our daily lives.

Software as a service (SaaS) is a software distribution model in which a cloud provider hosts applications and makes them available to end users over the internet. In this model, an independent software vendor (ISV) may contract a third-party cloud provider to host the application. Or, with larger companies, such as Microsoft, the cloud provider might also be the software vendor. SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS). A range of IT professionals, business users and personal users use SaaS applications. Products range from personal entertainment, such as Netflix, to advanced IT tools. Unlike IaaS and PaaS, SaaS products are frequently marketed to both B2B and B2C users.

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. A thing in the internet of things can be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low or any other natural or man-made object that can be assigned an Internet Protocol (IP) address and is able to transfer data over a network.

Robotics is an interdisciplinary branch of computer science and engineering.[1] Robotics involves design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics, electronics, bioengineering, computer engineering, control engineering, software engineering, mathematics, etc.

Augmented reality (AR) is the integration of digital information with the user's environment in real time. Unlike virtual reality (VR), which creates a totally artificial environment, AR users experience a real-world environment with generated perceptual information overlaid on top of it. Augmented reality is used to either visually change natural environments in some way or to provide additional information to users. The primary benefit of AR is that it manages to blend digital and three-dimensional (3D) components with an individual's perception of the real world. AR has a variety of uses, from helping in decision-making to entertainment.

A chatbot is an Artificial Intelligence program that chats with you. It can chat with you, provide information and support, book things for you and much more, how awesome is that. They are used to reproduce powerful interactions with users, to aid business processes, to gain information from large groups, as a personal assistant among others. Chatbots are also used by search engines to lag the web and archive new pages for future search.

Voice or speaker recognition is the ability of a machine or program to receive and interpret dictation or to understand and carry out spoken commands. Voice recognition has gained prominence and use with the rise of AI and intelligent assistants, such as Amazon's Alexa, Apple's Siri and Microsoft's Cortana. Voice recognition systems enable consumers to interact with technology simply by speaking to it, enabling hands-free requests, reminders and other simple tasks.

Personalization, also called one-to-one marketing or personalized marketing, is a marketing strategy where a brand customizes the content it delivers to the intended recipients to meet the customer interests, needs, and preferences. By using analytics data, such as customer demographics, browsing habits, and purchase history, brands can create ads that contain individualized messages to enhance buyer experience and increase customer engagement and loyalty. With personalized marketing, brands not only create buzz about their products and services but also develop a more personal and sincere connection with their audience. Customers receiving individualized content feel that the brand is communicating directly to them, which in turn motivates them to make a purchase.

Machine learning (ML) is the area of computational science that focuses on analyzing and interpreting patterns and structures in data to enable learning, reasoning, and decision making outside of human interaction. Simply put, machine learning allows the user to feed a computer algorithm an immense amount of data and have the computer analyze and make data-driven recommendations and decisions based on only the input data. If any corrections are identified, the algorithm can incorporate that information to improve its future decision making.

Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. The term may also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving. The ideal characteristic of artificial intelligence is its ability to rationalize and take actions that have the best chance of achieving a specific goal. A subset of artificial intelligence is machine learning (ML), which refers to the concept that computer programs can automatically learn from and adapt to new data without being assisted by humans. Deep learning techniques enable this automatic learning through the absorption of huge amounts of unstructured data such as text, images, or video.

Actionable insights are defined as insights which can help in making decisions and taking action. The insights which can trigger action can be called as actionable insights. These insights can be used to take informed decisions and help companies grow. Actionable insights can be derived from all form of analytics including descriptive, predictive and prescriptive analytics. Dashboards play a key role in bringing actionable insights to the stakeholders and decision makers as they provide a consolidated view of the data and insights. With actionable analytics, companies can drive better decision making and gain competitive advantage by doing so.

Web scraping is an automatic method to obtain large amounts of data from websites. Most of this data is unstructured data in an HTML format which is then converted into structured data in a spreadsheet or a database so that it can be used in various applications. There are many different ways to perform web scraping to obtain data from websites. These include using online services, particular API’s or even creating your code for web scraping from scratch. Many large websites, like Google, Twitter, Facebook, StackOverflow, etc. have API’s that allow you to access their data in a structured format. This is the best option, but there are other sites that don’t allow users to access large amounts of data in a structured form or they are simply not that technologically advanced. In that situation, it’s best to use Web Scraping to scrape the website for data.

Data mining is most commonly defined as the process of using computers and automation to search large sets of data for patterns and trends, turning those findings into business insights and predictions. Data mining goes beyond the search process, as it uses data to evaluate future probabilities and develop actionable analyses.

Big data is a combination of structured, semistructured and unstructured data collected by organizations that can be mined for information and used in machine learning projects, predictive modeling and other advanced analytics applications. Systems that process and store big data have become a common component of data management architectures in organizations, combined with tools that support big data analytics uses.

Net neutrality is the concept of an open, equal internet for everyone, regardless of device, application or platform used and content consumed. Proponents of the idea believe all corporations, including internet service providers (ISPs), should treat internet data and users equally. They should not restrict access, slow down access speeds or block content for some users to serve their own interests.

Bootstrap is a free, open source front-end development framework for the creation of websites and web apps. Designed to enable responsive development of mobile-first websites, Bootstrap provides a collection of syntax for template designs. As a framework, Bootstrap includes the basics for responsive web development, so developers only need to insert the code into a pre-defined grid system. The Bootstrap framework is built on Hypertext Markup Language (HTML), cascading style sheets (CSS) and JavaScript. Web developers using Bootstrap can build websites much faster without spending time worrying about basic commands and functions.

FileZilla is a free, open source file transfer protocol (FTP) software tool that allows users to set up FTP servers or connect to other FTP servers in order to exchange files. FileZilla traditionally supported File Transfer Protocol over Transport Layer Security (FTPS). The client software for FileZilla is available for all platforms and is free. Unlike the commonly chosen alternative form of security in FTP, secure file transport protocol (SFTP), FTPS is less firewall-friendly and requires the opening of a number of ports for its operation. For those who have security requirements for SFTP, previously a secondary client was required but the security has been updated to include both options.

Data visualization is one of the steps of the data science process, which states that after data has been collected, processed and modeled, it must be visualized for conclusions to be made. Data visualization is also an element of the broader data presentation architecture discipline, which aims to identify, locate, manipulate, format and deliver data in the most efficient way possible.
