Cloud Computing
The term “cloud computing” refers to the delivery of hosted services over the entire Internet. Infrastructure as a service, platform as a service, and software as a service are the three main types of cloud computing (SaaS) services. The cloud can be either private or public, depending on your preference. Anyone with internet access can purchase the service from the public cloud. This is a private network or data center that provides hosted services to a limited number of people with specific access and privilege settings. Cloud computing aims to make computing resources and IT services easily accessible and scalable, whether private or public. The hardware and software components needed to implement the cloud computing model make up the cloud infrastructure. For example, cloud computing is sometimes referred to as utility computing or on-demand computing.
There are many advantages to cloud computing, including
· Autonomous Integration of Software
· Almost Infinite Capacity.
· Creating a Copy of Everything Just in Case
· Affordability
· Ease of Obtaining Data
· deployment in a matter of minutes
· Cons of cloud computing:
· Connectivity to the Internet
Disadvantages of Cloud Computing
· Downtime
· Vendor Lock-In
· Limited Control
· Cost
· Security
Cloud Categories
Public Cloud
A public cloud is created when a provider provides computing resources such as computing power, memory, and data storage to the public over the Internet.
This type of cloud offers the highest economies of scale, is cheaper to set up because the cost of hardware, applications, and bandwidth is covered by the provider, and users typically use resources for storage capacity. And pay only the subscription fee. User or, for example, monthly.
Public clouds are usually run on open source software to facilitate the movement of such large amounts of data (3). The biggest weakness of the public cloud is security. When data is sent to the cloud, it can circulate in dozens, hundreds, or even thousands of systems. This is really scary for anyone running an application that contains secure data such as: B. Financial information or intellectual property in the life sciences industry. This model can also limit the specificity of configuration, security, and SLAs, and is not ideal for services that use sensitive data that is subject to all sorts of regulatory and privacy issues.
Private Cloud
A “private cloud” is a enterprise-owned computing infrastructure that has similar functionality to the cloud, but is completely internal and therefore more secure. However, this reduces most of the benefits of cloud computing. In general, a private cloud isn’t a cloud, it’s just a farm of internal resources that can only be used by your organization.
Private clouds can be expensive and are usually not an option for the average small- to medium sized business. They are typically put to use by large enterprises.
Hybrid Cloud
If your organization has different computing resource requirements and you have both sensitive and non-sensitive applications, hybrid cloud offers the best of both worlds. Database servers containing sensitive information are kept in a private cloud, and everything else is in a public cloud.
For pharmaceutical companies, the R & D database containing proprietary information is stored in a private cloud, and the marketing aspects of the company’s medicines, illnesses, and general information are stored in a public cloud. Private clouds can also help you share information with external partnerships, such as: B. Collaboration with other companies, CROs, CMOs-Still, companies can set the amount and amount of information parameters to share with whom.
This solves public cloud security issues and enables organizations to get the most out of what public clouds offer when it comes to common computing resources. For example, you can move individual applications or parts of them to the public cloud during peak hours.
