IT INFRASTRUCTURE
IT Infrastructure is the foundation or framework that supports a system or organization. In computing, information technology infrastructure is composed of physical and virtual resources that support the flow, storage, processing and analysis of data. Infrastructure may be centralized within a data center, or it may be decentralized and spread across several data centers that are either controlled by the organization or by a third party, such as a colocation facility or cloud provider.
Infrastructure components: Data center infrastructure often includes the power, cooling and building elements necessary to support data center hardware. The data center hardware infrastructure usually involves servers; storage subsystems; networking devices, like switches, routers and physical cabling; and dedicated network appliances, such as network firewalls. A data center infrastructure also requires careful consideration of IT infrastructure security.


DIGITAL MARKETING
Digital marketing targets a specific segment of the customer base and is interactive. Digital marketing is on the rise and includes search result ads, email ads, and promoted tweets – anything that incorporates marketing with customer feedback or a two-way interaction between the company and customer.
Internet marketing differs from digital marketing. Internet marketing is advertising that is solely on the Internet, whereas digital marketing can take place through mobile devices, on a subway platform, in a video game, or via a smartphone app.
In the parlance of digital marketing, advertisers are commonly referred to as sources, while members of the targeted ads are commonly called receivers. Sources frequently target highly specific, well-defined receivers. For example, after extending the late-night hours of many of its locations, McDonald’s needed to get the word out. It targeted shift workers and travelers with digital ads because the company knew that these people made up a large segment of its late-night business.
SECURITY
Security as a service is an outsourced service wherein an outside company handles and manages your security. At its most basic, the simplest example of security as a service is using an anti-virus software over the Internet.
With security as a service, security solutions are no longer delivered locally, where your IT department installs virus protection software, spam filtering software, and other security tools on each machine or on the network or server in your workplace, keeping the software up-to-date or telling them to use it. The old way of doing things is also expensive; you have upfront costs for hardware as well as continuing costs for licenses to allow you to use the software. Instead, security as a service allows you to use the same tools using only a web browser, making it direct and affordable.You work with the latest and most updated security tools available for anti-virus tools to be effective and useful, they need to work with the latest virus definitions, allowing them to stomp out threats, even the newest ones. With security as a service, you’re always using tools that are updated with the latest threats and options.
