What is Cloud Computing Security:
The study and practise of securing cloud computing environments, applications, data, and information is known as cloud security, or cloud computing security. Defending cloud environments against unauthorised use/access, distributed denial of service (DDOS) attacks, hackers, malware, and other threats is what cloud security is all about. While cloud security refers to security for cloud settings, cloud-based security refers to security services delivered via software as a service (SaaS) rather than on-premise hardware or software.
Cloud computing has several different types:
Not even all clouds are created equal, and not all cloud computing models are appropriate for all scenarios. A variety of models, varieties, and services have emerged to assist you choose the best option for your needs.
To begin, you must decide on the sort of cloud deployment, or cloud computing design, that will be used to create your cloud services.
Public cloud:
Public clouds, which provide computing storage over the internet and storage through the Internet, are owned and operated by third-party cloud service providers. The cloud provider owns and manages the hardware, software, as well as other infrastructure required in a public cloud. To utilise these services and manage your account, you’ll need a web browser.
Private cloud:
A private cloud is a collection of cloud computing resources utilised solely by one company or organisation. A private cloud might be physically located at a business’s datacenter. Some companies also pay for third-party service suppliers to host their private clouds. The essential services of a private cloud are operated on a private network.
Hybrid cloud:
Public and private clouds are combined in hybrid clouds, which are linked by technology that enables data and applications to be exchanged between them. A hybrid cloud allows your organisation more flexibility, more deployment options, and helps optimise your current facilities, security, and compliance by allowing data and apps to flow between private and public clouds.
The most important advantages of cloud computing security:
Cloud computing represents a significant departure from how organisations have traditionally viewed IT resources. Some of the most common reasons why organisations are turning to cloud computing services are as follows:
Cost:
Cloud computing reduces the upfront costs of purchasing hardware and software, as well as the costs of building up and maintaining on-site datacenters—server racks, round-the-clock electricity for power and temperature control, and IT specialists to manage the infrastructure. It quickly adds up.
Speed:
Most cloud computing services are self-service and on-demand, which means that even massive quantities of computing resources may be deployed in minutes, usually with only a few mouse clicks, offering Businesses have a lot more flexibility, and capacity planning is less stressful.
Global scale:
One of the benefits of cloud computing services is their ability to scale flexibly. That implies delivering the proper amount of IT resources—for instance, more or less computing capacity, storage, and bandwidth—at the right time and from the right geographic place, in cloud language.
Productivity:
On-site datacenters often need a great deal of “racking and stacking”—hardware configuration, software patching, and other time-consuming IT administration tasks. Because to cloud computing, many of these responsibilities are no longer essential, allowing IT workers to focus on more important business goals.
Performance:
The most popular cloud computing services are hosted on a global network of secure datacenters that are updated on a regular basis with the current generation of fast and reliable computing hardware. This has various advantages over a single corporate datacenter, including lower application network latency and higher economy of scale.
Reliability:
Because data may be duplicated at numerous redundant sites on the cloud provider infrastructure, cloud computing enables data backup, disaster recovery, and continuity planning easier and less expensive.
Security:
Many cloud services provide a comprehensive set of policies, technologies, and controls to help you improve your entire security posture and safeguard your info, applications, and infrastructure from attacks.
Different types of cloud services (IaaS, PaaS, serverless, and SaaS):
Cloud computing services are divided into four categories: infrastructure as a service (IaaS), platform as a service (PaaS), serverless computing, and software as a service (SaaS). Because they grow on top of one another, they’re frequently referred to as the cloud computing “stack.” It’s simpler to achieve your company objectives if you know what they are and how they differ.
Infrastructure as a service (IaaS):
During their most simplest form, cloud computing services IaaS allows you to rent IT infrastructure from a cloud service on a pay-as-you-go basis, including servers and virtual machines (VMs), data storage, networks, and system software.
Platform as a service (PaaS):
Platform as a service refers to cloud computing services that provide an on-demand infrastructure for building, testing, delivering, and supporting software applications. PaaS was created to make it simpler for developers to construct web or mobile apps rapidly without having to worry about setting up or maintaining the underlying infrastructure of servers, storage, network, and databases.
Serverless computing:
Serverless computing, which overlaps with PaaS, focuses on developing app functionality without having to constantly manage the servers and infrastructure necessary to do it. Setup, capacity management, and server administration are all handled by the cloud provider. Serverless architectures are flexible and event-driven, meaning they only use resources when a specified function or trigger happens.
Software as a service (SaaS):
Software as a service (SaaS) is a technique of distributing software programmes via the Internet on demand and usually by subscription. SaaS allows cloud providers to host and manage software applications and underlying infrastructure, as well as handle maintenance such as software upgrades and security patches. Users use a search engine on their smartphone, tablet, or computer to access the software over the Internet.
