What is Cloud Computing?
Cloud computing is the delivery of hosted software, storage and computing services over the Internet in a way that makes them accessible and manageable by remote clients. It provides scalability, portability, on-demand availability, low cost, and all these benefits through a software as a service (SaaS) model.
Cloud computing is a set of industry-specific technologies that deploy and manage applications. Cloud computing models are based on the ability to share resources among entities, such as companies and consumers.
Cloud computing encompasses dedicated hardware components, software, and services accessible through the Internet. There are different types of clouds:
A private cloud is a cloud infrastructure owned and operated solely by the organization it serves. It contains resources, such as computing, storage or network capacity, dedicated to said organization.
A public cloud is a type of cloud infrastructure over which the user has no control of access to the infrastructure or underlying hardware. Users can access from various locations but cannot control their network security and data privacy requirements.
A hybrid cloud is a mixture of the two architectures. It offers a blend of public and private cloud computing resources to create an environment that delivers elasticity and scalability.

Network function virtualization (NFV) is one of the top cloud technologies that has gained much popularity as it delivers an automated network infrastructure with modular building blocks. NFV is designed to improve business agility and service quality of new network functions.
Software Defined Networking (SDN)
SDN is a software architecture that allows businesses to create a flexible, manageable and scalable networking system. SDN can be used as a stand-alone technology or in conjunction with cloud computing to optimize the use of resources. SDNs are independent of hardware and employ software for their operation.
Internet of Things (IoT)
IoT is a concept that provides an environment where users can connect and use various wireless devices through the Internet to monitor, collect and process data such as temperature, humidity, light intensity and other environmental parameters to ensure the optimal functioning of the device. The IoT ecosystem allows businesses to integrate cloud technology on any access layer.
Machine learning is a set of algorithms that are responsible for the process of improving a solution based on past decisions that have been taken. A business can use machine learning to help deliver services with predictive capabilities.
Cloud Security and Privacy
The main drivers for cloud security and privacy revolve around the level of control, accountability and liability placed on cloud providers. Examples include scaling infrastructure capacity, moving resources among locations, deploying software patches and updates promptly, and minimizing costs.
Cloud as a Service (CaaS)
A CaaS environment provides all the functions related to cloud infrastructure, software and platforms. Users can access all these resources via one interface, accessible from various locations and instances.
Edge computing provides a distributed system of multiple cloud resources that can deliver trusted analytics using real-time data processing and advanced analytics techniques. Edge computing divides workloads into two categories: cloud-based and on-premises processing. Edge computing reduces latency and increases the overall performance of business applications by performing parallel processing from hard-to-reach locations.
